Clamps Clamps differ in purpose, device, material of manufacture, dimensions. They are used to fix various elements and details for their processing. Standard yews are suitable as an analogue, but they are difficult to carry and not all configurations of blanks are convenient to fix. The simplest mobile structure is a frame with a locking mechanism. It can be used by welders and carpenters in various situations.
Design and principle of operation
Regular clamp Clamp functionally resembles a yew, and its method of fastening is similar to the clamp of a manual meat grinder. The simplest manual version is a curved U-shaped monolithic frame, on one side movable fixing parts are attached to it. The last elements are most often a screw, one side of which is equipped with a handle for ease of operation of the device, and on the other side a flat wide plate. When the screw is rotated, it acts on the opposite side of the frame. If a pair of bars or similar parts are placed between the two parts, and then the working part is tightened, they will be securely fixed.
Case modifications
They are also called beam clamps. The fixture force can be used to fasten workpieces at parallel and oblique levels. The name of the instrument comes from the fact that the main action is performed by parts of the body (beams). Device - a pair of rectangular bars, which are interconnected with a reinforced bar at one end. This is a very useful tool.
The working element is statically attached to the bar, the second one is equipped with a tightening screw and moves freely. The reverse part of the bars is a clamping sponge. To hold the part, bring the metal beams all the way into the part, then tighten the screw element using the handle provided. This variety is the most popular.
Screw options
Screw (beam) clamps Clamps belong to the popular category of auxiliary tools. They are performed in several variations, while the main working element is a screw with a handle and a nose.
Modifications:
- A variant in the form of a body retainer, while the clamping part passes through the bar, and a nickel serves as a fixing lip.
- The frame is in the form of the letters "P" or G, a clamp with a plate passes through one leg.
- Screw versions made from tool steel made by forging. The metal after hardening has increased strength, which increases the reliability of the product.
Ratchet and magnet version
Clamp The ratchet clamp looks like a standard oversized clothespin. Fixing is done by hand. At the same time, the built-in ratchet mechanism locks the clamping lips. To loosen the mount, a special button or lever is used.
Magnetic clamp is the most popular among welders. This is due to the fact that it is used for preliminary fastening of metal blanks. The configuration of this instrument resembles an isosceles triangle, a five- or six-sided figure. Magnetic inserts are mounted on the walls of the device, which are responsible for fixing pipes or other metal products between themselves at an angle.
Modifications with hydraulics, trigger and vacuum
Hydraulic clamp The clamp is available on the G-shaped bed, as well as the screw counterpart. Also, a mechanism like a jack is used for the device, while there is no persistent nickel.
Trigger versions are equipped with one fixed jaw on a metal bar. The second part is equipped with a handle, which is made in the form of a pistol with a special lever. If the control flag is in the unlocked position, the movable part moves easily along the bar. When it is closed, the part is blocked, the clamp is made by pressing the lever. The movement of the sponge in the opposite direction is blocked by a lock. In general, the system resembles the design of guns for silicone.
Special suction cups withinjection handles. Their scope is holding two flat elements (MDF sheets, thin metal, glass) in the same plane.
Types of hand tools
Varieties of manual clamps Clamp and features of their design make it possible to effectively use the tool for various purposes related to the fastening of certain elements, regardless of their material, shape and configuration.
Some types are suitable for welding, others are useful in carpentry, others are used to connect parts of workpieces. Among the auxiliary devices of this type, a closing modification (mounting beam clamp Clamp) occupies a separate place. It can be classified as a full-fledged mounting element. It is designed to fix the profile to I-beams without the need to drill holes.
G-shaped model
An excellent helper when working with metal, made by forging. Key Benefits:
- high strength indicator, which makes it possible to securely fix several metal blanks together;
- fine-pitch thread provides good clamping effect, which is especially important when welding;
- no significant effort is required to securely fix the part;
- among the varieties there is a C-shaped variant;
- when working with wood, it is necessary to put safety pads under the nickel and sponge.
End and T-Locks
At the endlocking device cast or forged frame is made in the shape of the letter C, equipped with three screw clamps. They are placed by nickels relative to each other in parallel. This design is excellent for wood, guarantees excellent grip and fixation of workpieces. Most often, the product is used in the furniture industry for gluing overlays. The disadvantages include the need to hold the case and bezel while tightening the screws, which is not very convenient.
T-clamp differs in that a guide profile in the form of the corresponding letter is used as a clamp. Its length can exceed 100 centimeters, it serves to fasten movable sponges. A screw with a handle is used to fix the sectional elements. The device is often used in the installation of window frames and in furniture production.
Band and spring vise clamps (Clamp)
Tape versions are used by carpenters and coopers. This limitation is due to the special design (tensioning mechanism and rigid tape). The tool provides a load across the entire surface, which is good when creating barrels and other round products.
The main advantage of the spring latch is the ability to operate with one hand. It is shaped like a large clothespin. Among the minuses: lack of pressure adjustment, small grip, weakening of parameters during operation.
Tube Clamps
The basis of such a clamp includes a tube with a fixed jaw. Secondthe analogue moves freely along the base, is fixed with a separate stopper, the pressing process is carried out using a screw with a handle. The model is suitable for pasting preparations of the big area. As a rule, in such cases, a pair of clamps is taken to ensure uniform pressing on opposite sides of the shields.
