How to make splitter with their hands? Kinds of devices for splitting firewood: drawings, instructions
For the owner of a country or a private home is an indispensable device Cleaver. He is a mechanical or manual. You can purchase such a device in the store, but mechanical devices are expensive, so not everyone can afford, though, and can significantly ease the process of firewood.
Before making such an expensive purchase is necessary to think about the fact that such structures are not complicated, so they can make their own. But first, will determine the mechanical splitter, or it is better to supplement the engine. In the latter case it is necessary somewhere to look for spare parts, as well as to use the services of a turner. Well, if you have those skills themselves.
Varieties of devices for splitting firewood ax with displaced center
On sale today you can find an ax-ax off-center. For model Vipukirves Leveraxe have to pay 16,000 rubles. With the tool in a short time it will be possible to chop a large amount of wood. Provided such an opportunity due to the curved foot, located at the top of the blade. She clings to the remaining elements of the timber and forms a lever. As a result, the tool does not slip after the impact, and the legs remain safe. The design thus requires free grip ax.
Ax performed from Finnish birch, which is able to absorb shock pulse. Winter obmerznet handle not, it will not slip into the hands of even in the rainy weather. Due to the fact that the construction of such a unique ax, the blade gets stuck in the wood, because the center of gravity shifted instantly takes an ax to the side, so with a single blow breaks off a log plot. blade thickness equal to 8 cm, and weight - 3 kg. As the material of steel is used, and the folded tool dimensions are 91 x 23 x 9 cm.
What to consider before manufacturing
Before performing the cleaver is important to think about what they will not wave a little, but a lot of times. We conclude that the weight of the tool must be properly human physical form. For example, the market can find cleavers, the weight of which varies from 2 to 5 kg. However, using an easy tool, you can split a small block of wood, so you need to take into consideration the size of the wood.
tool handle, which is called ax handle, must be made of a timber type, or maple elm, in extreme cases it may be birch. After all, inaccurate and bounces tool will become worthless. It is important to take into consideration the length of the ax - it should not be too short. If you decide to perform a cleaver with his hands, it is more convenient to have two tools. One of them must be a powerful ax with a long handle, while the other - a classic wedge-shaped splitter. Last suitable for the fresh chopped wood has a high moisture content, while the other will deal with dry logs. Different species of wood will behave differently. And if you have on hand two cleaver, you can find an approach to them.
Before you perform a cleaver with his hands, should be to find a suitable design. Homemade tools are hydraulic or screw, the latter also called cone. The most common are homemade or screw factory options. As the base part protrudes cone with a large thread, which is driven by an electric motor. Master only need to move the deck only to the cone, the latter starts to be screwed into it.
Conical cleaver has a corresponding shape, from which the wood is split into 2 parts. If we are talking about the hydraulic choppers, they will have a higher performance than the above, but to make them more difficult. The principle of operation remains the same as that of the hydraulic press. Wood is forced through a special form, which splits the element to the desired size logs. The mechanisms of the machine is a hydraulic actuator which acts on a gasoline or electric motor. Cone cleaver is more convenient for firewood compared to a conventional ax. To make such tools is simple, but the market can find ready-made kits for the assembly of such devices.
If you are thinking about how to make the splitter screw, you should first prepare the following materials and components:
- a drive belt;
- sheet metal:
- the plate for fixing the motor;
- shaft bearings;
- working cone;
- shaped pipes;
- metal corners.
When selecting the electric motor is necessary to pay attention to the one that has a capacity of 2 kW. The sheet metal should have a thickness of 3 mm.
Homemade ax for firewood can be manufactured much easier if we can find a powerful low-speed electric motor, which is capable of producing 500 rpm. At the same belt drive is not required, and the cone can be put on its shaft.
The engine speed is, in principle, can be anyone, but to calculate the belt drive pulleys must be such that the speed was 500 revolutions per minute. In the market you can buy ready-shaft bearings for electric cleaver, but the pulleys and threaded cone can be manufactured by contacting a turner.
If you decide to make a cleaver with his hands, then as material for the cone will make carbon steel, it is better to use a brand of ST45. In the preparation of the thread must be considered that it should consist of two approaches. Step is 7 mm, whereas the height of the turns - 2 mm.
Of ordinary steel St3 can carve pulleys and the groove dimensions will depend on the chosen belt. Experts used instead of the belt drive chain. It is more reliable, but more difficult in the manufacturing process. It is important to choose the sprocket size that is not very convenient. To collect the ax with your hands, you need to cook a frame, setting the plate for fixing the motor under the table. It must be positioned with the shaft bearings. A pulley fixed to it and a cone. Next, the wizard will have to put on and pull a belt. Motor connection to the network is in the next step can then move on to testing.
Manufacturing hydraulic cleaver
The hydraulic splitter has a structure different from the previous one. As features and acts actuator operating part used for breaking the material. The frame has a different shape, though of welded parts, pipes and sheet metal. Press splitter operates by the hydraulic cylinder, the pressure in it is provided an oil pump. Set the active element must be on the same shaft with an electric motor, the assembly may be located separately from the frame, but it is to be connected to the cylinder, using hoses.
If you decide to make a hydraulic splitter, you should first find all the details and take care of the production of forms. It is made of metal, and as a base boss cruciform shape. Its size can be selected individually, because there are no clear limits. The main condition for this is that the power cylinder was sufficient for splitting firewood, when their size is too large.
The form must be secured to the frame and its transverse axis must coincide with the shaft of the hydraulic cylinder. It is installed along the frame and connected to the pump, thus it is necessary to use pipes. Such mechanical splitter can be movable, for it to be strengthened wheel frame.
How to make a cleaver
Firewood requires considerable effort: they need to saw, chop, add to Accessories for drying. Most power goes out to chop firewood. Facilitate and accelerate the process may cleaver. They are represented in sufficient numbers, but are respectable money. At the same time, to make the simplest cleaver own hands can be of metal - pipes, corners, etc. All require literally thousands - if not metal, it will have to buy.
If the volume of firewood are small, they are easy to handle mechanical cleaver. They are characterized by simplicity of design, the minimum number of complex assemblies, as well as the fact that the costs are minimal, even if the economy is not suitable piece of iron.
The easiest and safest option. The only pity poor performance. but safe
Simple cleaver own hands: mechanic
The simplest mechanical resembles a cleaver sump crane. The design of one to one, but instead of buckets fixed cutter and a handle. The connection supports (pillars) and the beam can be made most simple - hinge. Only need good lubrication.
The principle of operation is probably all clear. Block of wood put on the stand, sharply pull down the lever, due to the inertia force tool is gaining significant power and splits the block of wood. The process is repeated as long as will not produce the desired thickness of the logs.
The easiest cleaver collect their own hands can be of several pipes
Such a mechanical cleaver with his hands just to collect, and, literally, from the fact that there is - pipes, angles of any size, even an ax can be used as a torch. In addition, such a design can be made collapsible - to be able to tolerate it.
Many minuses. FIREWOODPROCESSORS requires considerable effort. And the more effort is exerted to stop the move cleaver after a log fell apart. Another minus - like cleaver occupies a substantial area, because the longer the lever, the less effort it is necessary to apply. Nevertheless, even such a primitive mechanical device is much reduces the complexity of the process.
One option - Cleaving is welded to the square pipe grouted
In this configuration splitter should be heavy. Because the blade itself is welded to the all-metal ingot. More affordable option - be welded to the tube (round or square) and fill it with concrete. Agree to make such a cleaver with his hands on forces anyone who knows how to handle the welding machine.
There is a modified design of the manual mechanical cutters, and which, in a smaller, chopping wood better, requires less effort. In this model, the main operating unit - a spring which is fixed on the frame, and the upper part rests on the fixed crossbeam, on which there is fixed splitter.
The design of the spring woodsplitter
In this construction, the main effort - hold Cleaver after log split - assumes the spring. Accordingly, the main thing - to choose the spring and focus so that minimal force were applied, but they were enough to crack even complex, knotted block of wood. The emphasis under the spring can be made movable. Then you can adjust the settings to suit the specific conditions. In reality, the "resetting" is required for a particular person. If you work with an instrument will be one person, we can do everything stationary, picking height empirically.
It is equally important to make movable articulation of the frame and lever, which is mounted splitter. The best option - bearings. They must be of good quality, it is desirable - self-leveling.
Ready homemade spring cleaver
The minimum height of homemade woodsplitter - about 800 mm. But then you have to work or stooping, or install the machine on a table / base frame. A more comfortable alternative requiring minimal effort - made for its growth. Determine at what height you are comfortable to stand on a log, add to this figure the height of the block of wood, get the height of the frame. In this case, too, will have to bend, but only when installing the chock on the stand, and not every time the ax falls.
To add mobility design, cook a frame, on the one hand a fixed wheel, the second welded stops. Make a cleaver with his hands a bit more complicated, but if there is a spring and bearings - and it is such a difficult task.
Splitter inertial vertical
Another simple option for independent production. To make such a cleaver with his hands need two tubes of larger and smaller diameter. Another need heavy plate - a base, and, in fact, stitching part - cutter / splitter.
Construction - one of the most simple, requires little effort. On a massive platform secured a thick-walled pipe, but better - the pin. Height - about one meter. It is the leading pipe. As it moves freely splitter, which is welded to the pipe rings of slightly larger diameter than the lead pipe. He chops wood as follows: pick up the ax and let him go. You can give a little downward acceleration. By gravity log splitting.
But this mechanical cleaver splits once not all the block of wood. To increase its effectiveness, on the splitter can be done weighting. It is possible to "add" if necessary. The second option - hit a couple of times over the column with a hammer. This method is good if the tool is stuck in the wood. The alternative - to lift up and block of wood with sharply lower. But hammer wave easier.
Handheld cleaver, of course, makes it easier to get firewood, but still requires a solid physical effort. Not as much as they spend waving the usual cleaver, but still ... Make an effort even lower helps motor. On its basis, wood splitters make different designs. But to make such a cleaver with his hands more difficult. And then the device is more complicated and requires at least minimal knowledge of electrical -zhelatelno connect the motor through a starter, and with the "Start" button and "start".
One of the most popular models - tapered screw or cleaver. The difference between them is only in the absence / presence of the thread on the pricking element, which in this model is in the form of a cone.
Conical cleaver accelerates firewood
Block of wood split by the fact that the rotating motor cone cuts into the wood, slowly tearing apart. In a large block of wood chips first edge and then tear the middle.
First machined cutting part in the form of a smooth cone. If you use a smooth cone at the falls is quite lean on the block of wood to the cylinder 'bite' into the wood. It is much easier to process if threaded on its surface. In this case, block of wood, as it were screwed onto the screw, and then split.
Dimensional drawing cone threaded for screw woodsplitter
The main thing - the right to make a cone with thread. If you have a lathe and experience you can try to make yourself. If not - will have to be ordered. Thread to do different, but optimal recognized the following parameters: Step 7 mm, depth 3 mm (minimum - 2 mm). Another important point - the depth of the seat of the motor reducer - not less than 70 mm.
If a cone threaded, make the cleaver with his hands in the cellar.
Needed sufficiently powerful electric motor (2 kW or higher, or 5.9 l / s), but with a slight speed: 250-600 revolutions / min. At 250 rpm and below the tunic very slowly, and if speed is more than 500 - work is dangerous, that it may pull out a piece of wood out of hand.
Splitter with screw, wear directly on the crankshaft
If unable to find the engine with such parameters can be made peak (screw) to impose directly on the crankshaft (pictured above). If the speed is greater need to set a reduction gear or to make a chain or belt drive to reduce speed.
The ratio is calculated as a function of engine speed. For example, there is the engine for 900 revolutions. Having reducer 1: 2 obtain 450 revolutions / min. Just the best option.
Reduction gear for screw woodsplitter
Transmissions can be belt or chain. Continued work at times louder require constant strokes, and carve asterisk stands with the necessary parameters are usually more expensive. Double belt drive is desirable (as pictured above). In this case, the smaller will be the slippage.
If the design provides for the transmission, the motor is better to put at the bottom, and the screw is fixed on the work surface. Select the height of the work surface under its growth, it was not necessary to work in the slope.
Safer model. Make a cleaver with his hands - significantly simplify your life
There is still such a parameter as the height of the rotor above the work surface. The gap from the table to the cylinder must be in the region of 8-20 cm above the positioning is not necessary -. Can turn the block of wood of small diameter. Optimal distance -. 8-12 cm Even small-size block of wood does not turn.
Hydraulic cleaver - the most powerful but also the most complex and expensive to manufacture. In addition to the frame, the engine and the cutting knives need a hydraulic cylinder of sufficient capacity. Are they are not cheap. In addition, we need more oil tank and pump.
Apparatus hydraulic cleaver
Hydraulic firewood splitter develops solid efforts during its manufacture because metal is used a considerable thickness - 6.10 mm, depending on drive power. Force that is enough to at once destroy the chock 6-8 logs. Because the blades are made in the form of a "star".
Log splitter with hydraulically fitted with sophisticated cutter block of wood that falls apart into several logs at once
In the manufacture of knives spaced from each other by a few centimeters. So that the work was only one. For example, the first - horizontal, then - vertical, then - right at the end - left. Thus, each of the blades amplifies, privarivaya rear reinforcing plate. Steel is desirable to use a rigid, pre-confining it in the same way as in the splitter.
Gasoline cleaver works quite quickly, though hemp birch. I had to chop using colon elm - this is where the real confusion, ax stuck in the wood. Judging from the video, gasoline cleaver has to cope with an elm.
Types of firewood splitter and their manufacture
Screw electromechanical cleaver Cleaver
Modern wood processing technologies have gone far in the development, therefore there were various "helpers" Woodman:
- Cleaving Machine is used in industrial applications, where a large wood processing speed is required. The mechanism is actuated special machine and additional weighting (from 100 kg to 1 tonne, depending on the model). Often, a mechanical device found in the household. And some of them local artisans make their own hands. The mechanism is actuated by a spring, which is attached to the operating handle. After terminating movement creates the spring resistance, due to which counterweight returns to its original position. Device for chopping wood is driven by mechanical arms efforts.
- Cleaving Machine drive. In this type of commoners a cleaver known as electric. By the principle of action is the same as above. The only thing that indicates their differences - a motor that actuates all the equipment. Mechanical tools for splitting firewood often make their own hands in the countryside or in the cottages.
- Hydraulic cleaver. This type of mechanism uses the energy of the compressed fluid. The basis of the mechanism of action based on the principle of the hydraulic press. Most models equipped with additional blades, which occurs at the expense of splitting the workpiece to several parts.
- Splitter on the screw gear. This type of device operates on a screw transmission, that is, his work is based on the conversion of the rotational motion cleaver Outside screw into linear motion of the nut. This splitter firewood copes well with its task. This model is characterized by high productivity and accuracy. Their own hands to make such equipment is nearly impossible and even dangerous.

Cleaver firewood with their hands
Not everyone has the opportunity to buy an expensive model, so most of the summer residents and rural residents prefer home made of wood splitter. Practice has shown that with his own hands, you can do a lot of things. Let's get started.
For manufacturing you will need: drawing device, a thick sheet of steel (approximately 10 mm), welding, hammer and pliers. Thick sheet steel is sharpened on both sides at an acute angle on the grinding machine. At the end should get a double-sided blade sharpening. It should be noted that the work with the grinding machine takes too much time, so for speed you can use the grinder - cut the unnecessary pieces of steel angle. Scrap is ground on the grinding machine to the required parameters.
The side plates which are also welded to the steel plate are manufactured from a sheet of stainless steel 5 mm thick. Both edges are sharpened at an angle of 45 degrees. This is done so that in the moment of impact, nor there is a strong resistance on the part of an improvised device. For welding metal plates, you will need an assistant who will hold the workpiece with your hands while you are working with welding.
Homemade ax for firewood
To provide additional structural rigidity of the plate can be fixed pin M8. The plates are made with their own hands, superimposed on the fabric at an angle of 45 degrees, this is the main requirement. The inserted pin must wear a rigid spring, which will perform the role of the shock absorber during impact. The spring is fastened nuts is the same size as the pin.
Cleaver firewood is almost ready, it remains to be welded eyelet into which is inserted an ax. As the eyelet blanks can be used with water pipe diameter of 40 mm and a length of 80-100 mm. To cut a thick pipe you need help partner - the way he holds his hands the pipe, while you cut.
Round pipe must flatten using a hammer. Hit the metal tube is necessary as long as it begins to acquire an oval shape. Pomuchat bit and for receiving hole ax oval welds it to the workpiece.
As for the arms, do something it can also be their own hands. Specific requirements for the ax handle not, the main thing that you were comfortable with it to work. Long handle reduces accuracy and increases the force of impact.
The principle of operation of such a cleaver rather simple: when struck by the end part of the wooden web edge sharpening penetrates inwardly. One has only to web delve more than 20 mm into the wood dig further sharpened side plates. The deeper splitter enters into the timber, the stronger side plates move apart, breaking the timber into two pieces. This model is good because it does not require from its owner long to adapt to the device. Already after a few strokes you will learn how to dissect a piece of wood at a max.
Thus, manufacturing cleaver no different complexity of the process and does not require special skills or human skills in the use of tools. All that is needed - this is clearly adhere to the drawing and re-read the instructions carefully before you do something.
