Carpentry clamps: description and characteristics

Joiner's clamps belong to the category auxiliary tool, the main purpose of which is to fix parts in one position when performing work. To ensure a strong fixation of the movable mustache, there are special notches on the rod that engage the movable sponge. The tool is equipped with a special rotary handle, which is directly responsible for fixing the clamps in a certain position. Carpentry clamp guides are made of profiled steel, which is durable and resistant to deformation. In our online store you can buy clamps for joinery and carpentry work with blanks different size.

Types of carpentry clamps

In our store you can wholesale and retail joinery clamps of the following types:

• . The design of such devices allows you to work with workpieces of different thicknesses. F-shaped clamps are often purchased in bulk in carpentry shops, where large amounts of work are initially implied.
• . In such instruments there are no backlashes of the lips. G-clamps are suitable for those who do not plan to work with a wide range of workpiece thicknesses.
• . The peculiarity of such devices is that they are suitable for use as spacers.
• . The design of such models allows you to place workpieces at different angles, and when you press the trigger, the “vise” instantly opens.
• . Pistol-type devices are convenient to use for carpentry, plumbing and even welding work. The main advantage is the ability to work with workpieces of different thicknesses.
• . These tools are usually used to work with products such as window frames, door frames etc.

Clamp - quite simple in appearance carpentry tool, but it is widely used in many types of construction or renovation. Its main function is to clamp one or more parts and fix them for a long time.

Purpose and scope

As a classic example of the application of the product, one can imagine exactly how the gluing of two wooden surfaces. After applying the adhesive, it is necessary to closely press the parts for long time up to a day. They are fixed with a clamp and are in this position for the entire necessary period.

Also, the clamp is a structural element of many plumbing or household appliances. With it, the vise is attached to the workbench, and the meat grinder to the countertop. Some species table lamps also have this simple detail in their design.

Varieties

The device of a joiner's or locksmith's clamp is quite simple. It consists of a frame in which there may be a movable part. With it, the frame can be "pulled apart" by required distance. Thus, you can adjust the distance between the jaws, achieving optimal value. At all simple mechanisms have one fixed frame, depending on its size, the one that fits the criteria is selected. By the way, you can buy a clamp at this link - airtools.pro.

The second element is a clamping mechanism, with the help of which the sponges are directly clamped, between them there will be material for fixation. By turning the screw, you can adjust the required compression ratio.

By outward signs, which affects the scope, the clamps can be divided into three types: G and F shaped, in outline they will resemble these letters; as well as automatic.

• G. Perhaps the most classical form products and the simplest. Very handy when working with wooden objects, metal products. The two bars are simply clamped by the moving part with a screw or lever. When buying, you need to check the clamping mechanism and inspect the frame for chips, as it is often cast iron and can be fragile.
• F. Caliper-like shape. One part of the frame is fixed, the other moves according to the "sliding" principle. Having squeezed the material between the jaws, you need to squeeze it and fix it with a clamping mechanism. The advantage of this type is the large stride and jaw gap.
• Automatic. They are quite identical and similar to each other. Via automatic drive you can fix parts with one hand.

Before the purchase

Due to the fact that the clamp is quite simple in its design, choosing it will not cause any difficulties. First you need to decide on the necessary working stroke of the clamping part so that it meets the requirements. Check the quality of the device, the absence of cracks. Roll up to the stop rotary mechanism and look at the tightness of the sponges, also make sure that they are even in structure.

You should always remember that sponges, when compressed, can leave dents on a soft surface. Therefore, check the presence of gaskets, if any are included. If not, it doesn’t matter, they can always be made at home from improvised material. It must be remembered that the gaskets must be from more soft material than the clamped part.

In the process of woodworking, in most cases, a joiner's clamp is indispensable. Is it necessary to glue wooden blanks, fix the sheet, board, slab during cutting - a clamp will definitely be needed. There are similar products on sale, but, according to reviews experienced craftsmen, they are characterized by two significant drawbacks - a limitation in size and low strength, since soft metals (alloys) are mainly used for their production in order to reduce costs.

Those who have to work with wood quite often prefer homemade carpentry clamps. How to make such a device with your own hands, what to pay attention to and take into account - this is described in the article.

There are many modifications of carpentry clamps - angular, G-shaped, edge, universal. Some are used for permanent work with various blanks (by area, thickness), others are made for a specific technological operation (for one-time use).

The author considers it appropriate to dwell only on those that are most often used by "home craftsmen". If the principle of their functioning becomes clear, then with your own hands you will be able to make any kind of carpentry clamp, according to your own requests. Unless, of course, "turn on" the fantasy and think carefully.

The author deliberately does not indicate the linear dimensions of the clamps. One of the advantages of their self-manufacturing consists in the possibility of an arbitrary choice of the shape and dimensions of carpentry clamps. There is no standard for such devices. And it is hardly advisable for a person who is accustomed (and knows how) to do everything with his own hands to “chew” elementary things. The main thing is to give an idea, to “suggest an idea”, and everything else is at your own discretion.

Option number 1

The simplest modification of the clamp. It is done quite quickly, but the use of such a joiner's clamp is somewhat limited. Although in most cases, when working with small-sized samples, it is quite enough.

The frame of a hacksaw for metal is taken as the basis of the device. The fastening elements of the canvas are replaced by long threaded rods, at one end of which there is an iron “patch” (as an option - a nut), at the other - either a removable handle, or a cap for an open-end wrench.

Since the frame can be adjusted in length, such a clamp will allow you to fix the workpieces different thickness. It is mainly used when gluing parts (), since the body of the fixture itself cannot be fixed on any surface. The only thing to consider is that if the frame is collapsible (the old modification of the “hacksaw”), then you will have to put a “tire” at the bend (for example, wrap it with adhesive tape). In operation, such a clamp is not entirely convenient, but in the absence of something more suitable, it is a good solution to the problem.

Option number 2

Also pretty simple model clamps. It is done by hand relatively quickly. The device of the device is clear from the figure. All you need is a metal corner and a couple of long screws or threaded rods.

If you make several of these clamps, then with their help it will be possible to perform various carpentry work. For example, glue long workpieces. To do this, it is enough to set the clamps at a certain interval, and lay between the stops and the processed sample metal strips or slats of hardwood. Alternatively, fix the assembly on a workbench. The same applies to cutting blanks.

Before sawing, they are fixed on the tabletop, and their immobility will be guaranteed. This design can be modified by welding metal plates to the corners. This significantly increases the clamping area.

Essentially, for domestic use this modification of the joiner's clamp is one of the best. Experienced craftsmen always have a ready-made set of several devices with different dimensions at hand. Depending on the specifics of the work, you may need a clamping device from a corner either 25 or 45.

The versatility of such a modification is that it is made of metal, therefore, it is characterized by sufficient strength. Unlike wooden clamps, here you can adjust the clamping force in a wide range, and work not only with wood, but also with other materials - glass, plastics, and iron. What in everyday life and often have to do.

This design can be somewhat modified. For example, when processing logs at a mini-sawmill (cutting into boards, sawing), they must also be fixed. In this case, an improved modification of such a carpentry clamp is suitable. It is enough to take strip iron as its basis, at the ends of which to weld the same corners.

Varieties and modifications

Here are a few more types of carpentry clamps. All these clamps are easy to assemble with your own hands.

The question is different - how expedient is it to use wood as a starting material? There are arguments both for and against. But if a tree is chosen for the base of a joiner's clamp, then it must meet certain criteria.

• The breed is only hard (pear, oak, walnut and the like). Otherwise, there is no need to talk about any clamping force. And the durability of the clamp of their “soft” wood raises certain doubts.
• Humidity is minimal. Only after high-quality drying of the material can it be used for the manufacture of clamping parts.

Good luck, reader, in making your own clamp. Do not be afraid to fantasize, and everything will work out for you!

A clamp is a tool that allows you to fix a part during processing. Masters often use different kinds clamps at work. Whether it is a carpenter, or a metalworker, there is always a need to use it.

This device is available in different options from universal to specialized. Relatively recently, a new modification has appeared: a quick-clamp clamp. Develops compression force up to 450 kg.

The task for all types is common - to fix the workpieces for processing or connecting to each other.

Like any other tool - clamps can be purchased at the store or made independently. The second option is often chosen by professionals. It’s easier to come up with your own design than to look for an option for individual tasks.

Homemade clamps - varieties and manufacturing technologies

Angle clamp

Such devices are used to fix two objects (not necessarily of the same size) at a right angle, to connect them together in any way. These can be wooden blanks when gluing, or assembling with the help of corners and confirmation.

However, most often, an angle clamp is used as a jig for welding. metal parts at a right angle.

For manufacturing you will need:

• steel corner 40 mm, 3-4 mm thick;
• steel plates 40-50 mm wide;
• threaded studs, preferably hardened;
• bars for collars;
• nuts for the worm mechanism;
• welding machine;
• drill, taps.

We weld the corners to steel plates strictly at an angle of 90 °.

We attach a worm structure to each side by welding. This is the same corner with a welded stop nut or thickening, in which the thread is cut in accordance with the hairpin. The width of the working gap is selected for potential workpieces.

IMPORTANT! If the range of workpiece sizes is too wide, it is better to make several clamps. Too much stroke of the knob does not contribute to a strong fixation.

A stud-knob is screwed into the working nut, after which an emphasis is assembled at its end. As a rule, this is a design of two metal washers different size. The stop should scroll freely on the hairpin.

Clamp (German Schraubzwinge, from Schraube - screw and Zwinge - vice) - a tool used to fix any parts or materials at the time of processing: sawing, gluing, joining, drilling, welding. Clamps are made of various materials: metal, plastic, wood and are different in design: screw, lever (quick-clamp). Clamps are used for carpentry and locksmith work. Clamps for plumbing and welding are usually made entirely of metal. Clamps for carpentry work can be made of metal, wood and plastic.

Clamp types:

F - shaped clamps usually consist of a metal bar on which a fixed jaw and a movable jaw are mounted. Sometimes the fixed sponge is an extension of the tire. A clamping screw with a wooden, plastic or metal handle is installed on the movable sponge.

H and the movable jaw can be equipped with a quick-clamping mechanism that allows you to quickly fix the material. F - Piher shaped clamps with a special clamping mechanism allow fastening materials with a high force up to 10,000 N. The double clamping screw is protected from dirt.double clamp threaded screw- the rotational movement is converted into translational, which prevents the workpieces from moving when they are clamped.

To fasten "delicate" materials that do not require strong clamping force, clamps with wooden sponges are used, on which cork linings are glued. Have the big range of thickness of the fastened materials.

G - shaped clamps– the tire, upper and lower lip are a single one-piece cast structure, a clamping screw is installed on the lower lip. The main advantage is the absence of backlash sponges. The disadvantage of these clamps is the small range of thickness of the fastened materials.

Angle clamps- allow you to clamp parts at a right angle. Angle clamp consists of a body and one or two screw clamps, on which clamping heels are installed.

End clamps (clamps for edges)- allow you to press the material to the end face of the part. Similar in design to G - shaped clamps, but have two additional clamping screws.

Quick release clamps - have various designs, the most common quick-clamp clamps consist of a metal bar on which plastic jaws are mounted. The movable jaw is pressed by a lever mechanism, it is also possible to rearrange the fixed jaw to the opposite end of the tire and use the clamp as a spacer.

Band clamps - the design of the clamp has a tape of metal or of synthetic materials and a clamping screw that tightens the tape. Tape clamps are used to assemble and glue oval, round and polygonal structures
