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.
How to choose a mechanical chopper for wood
More recently procedure firewood manually accompanied by unpleasant effects such as general fatigue and blisters covered hand. Fortunately, progress is not standing still. Today, to help owners comes motorized ax for firewood. Machine tool saves time and effort, and quickly prepare such volumes of wood, which previously could only dream of. Let us see what are these units.
Cleaver firewood mechanical - effective assistant in the household. Apply it is possible not only in the procurement of wood for heating homes, cottages or bath, but also for commercial use (the provision of public services, the organization of the mill). Much depends on the performance of the unit. However, even the most low-power splitters for firewood able to replace the efforts of several experienced loggers.
Structurally, the device of this type consists of the chute for stacking logs, timber feed mechanism, the stop and the cutting part. The necessary force can be generated hydraulically or helical manner.
Use of a mechanical chopper for wood is quite simple. The task of harvesting huge volume of wood is able to handle by one person. enough time to load logs onto the platform, to make them hold and press the lever. To select the most suitable solution for the existing needs, it is necessary to understand the basic types of wood splitters and their differences.
The simplest type of destination devices. Structurally conventional screw cleaver consists of a metal body, the cone mechanism and the cutting edge. The advantage of these machines is the ease of use, small size and affordable price. Well suited for screw splitters meet the needs of the wood country house or a small boiler.
Among the disadvantages of such a solution it is worth noting the relatively poor performance, as well as manual feed logs. Therefore if necessary the workpiece substantial amounts of wood block of wood a wood splitter for inefficient.
For processing large batches of logs it is recommended to use a hydraulic press. The main power cylinder element appears here. At a force that is generated by fluid pressure, it is set in motion the cutting stock. The design also provides a motor and pump. You may want to collect such choppers for firewood by hand.
If you decide to give preference to the factory model, it is necessary to pay attention to the following points:
- Force the split - depends on the size of the cylinder, the engine performance and power.
- Dimensions of devices for supplying logs.
- blank layout method - horizontal or vertical.
Hydraulic firewood splitter can become good helper during harvesting because aggregates of this category have a high productivity. Successfully used these machines in a residential and commercial sawmills.
Models in this category include a gear, which is responsible for the movement of the cutting edge. The standard design includes engine splitter, belt gear.
The logs are placed between the cutting blade and the protective stop. When activated, the clutch gear mechanism occurs, whereupon splitter begins to move toward the block of wood, splitting it in half. mechanism elements are returned to the original position after the removal of the logs and pressing the corresponding knob.
To find an effective rack unit for firewood, should focus on a few defining moments:
- The strength of the splitting.
- Maximum length of workpieces.
- Form cleaver (some models include cutting edges that can separate the block of wood into several pieces in one parish).
To date, available to the domestic consumer plurality of individual modifications slatted wood splitter, which vary according to technical and functional capabilities. Therefore, to decide a worthy goal, it is necessary to focus on the amount and complexity of work that must be performed.
Currently, the most reliable solution for harvesting wood block of wood can become a factory mechanical wood splitters professional brands. Unlike products autographic or handicraft production, they have a more impressive performance margin. However, the price of these units is quite high. Therefore, the purchase of a professional machine to perform household tasks may prove to be a waste of resources.
If necessary, use cleaver for firewood in the household is recommended to give preference to products of lesser-known producers. At the same time should pay attention to build quality and availability guarantees.
