Clamps Clamps differ in purpose, device, material of manufacture, dimensions. They are used to fix various elements and parts for their processing. Standard yews are suitable as an analogue, but they are difficult to transfer and not all workpiece configurations are convenient to fix. The simplest mobile design is a frame with a locking mechanism. It can be used by welders and joiners in various situations.
Design and principle of operation
An ordinary clamp Clamp functionally resembles a yew, and its mounting method is similar to a manual meat grinder. The simplest manual option is a curved U-shaped monolithic frame, on the one hand movable fixing parts are attached to it. The last element is most often a screw, one side of which is equipped with a handle for easy operation of the device, on the other hand - a flat wide plate. When the screw rotates, 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 firmly fixed.
Case modifications
They are also called beam clamps. The force of the device can be used to fasten the machined elements 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). Fixture - a pair of rectangular bars, which are interconnected using a reinforced bar at one end. This is a very useful tool.
The working element is statically attached to the bar, the second is equipped with a pulling screw and moves freely. The back of the bars is clamping jaws. To hold the part, it is necessary to bring the metal beams all the way into the part, and then tighten the screw element using the provided handle. This variety is the most popular.
Screw options
Screw (beam) clamps Clamp 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 patch.
Modifications:
- An option is in the form of a body retainer, with the clamping part passing through the block, and the nickname serves as the fixing lip.
- A skeleton in the form of the letters "P" or G, a clamp with a plate passes through one leg.
- Forged screw versions of tool steel. The metal after hardening has increased strength, which increases the reliability of the product.
Ratchet and magnet version
Clamp Clamp with a ratchet looks similar to a standard oversized clothespin. Fixing is done by hand. At the same time, the mounted ratchet mechanism locks the clamping lips. To loosen the mount, use a special button or lever.
Magnetic clamp is most popular among welders. This is due to the fact that it is used for preliminary fastening of metal blanks. The configuration of this tool resembles an isosceles triangle, a pentagonal or hexagonal figure. Magnetic inserts are mounted on the walls of the device, responsible for fixing the pipes or other metal products to each other at an angle.
Modifications with hydraulics, trigger and vacuum
The hydraulic clamp Clamp is available on the G-shaped bed, as well as a screw counterpart. Also, a mechanism similar to a jack is used for the device, while there is no persistent nickel.
Trigger versions are equipped with one fixed sponge 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 displayed in the unlocked position, the movable part moves easily along the bar. When it is locked, the part is locked, pressing is done by pressing the lever. The movement of the sponge in the opposite direction is stopped with a lock. In general, the system resembles the design of guns for silicone.
Special suction cups with discharge handles are installed on the vacuum device. Their scope is to hold in the same plane two flat elements (MDF sheets, thin metal, glass).
Types of Hand Tools
Varieties of hand clamps Clamp and the 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 the workpieces. Among the auxiliary devices of this type, a closing place is occupied by the closing modification (mounting beam clamp Clamp). It can be considered a full-fledged mounting element. It is designed to fix the profile to the I-beams without the need for drilling holes.
G-shaped model
An excellent assistant when working with metal, made by forging. Main advantages:
- high rate of strength, which makes it possible to reliably fix several metal blanks with each other;
- fine pitch thread provides a good clamping effect, which is especially important when welding;
- significant effort is not 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 nickle and sponge.
End and T-shaped clamps
At the end fixing device, the cast or forged skeleton is made in the shape of the letter C, equipped with three screw clamps. They are placed in nickels relative to each other in parallel. This design is perfect for wood, it 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 body and the pad, while tightening the screws, which is not very convenient.
A T-shaped clamp is characterized in that a guide profile in the form of a corresponding letter is used as a clamp. Its length can exceed 100 centimeters; it is used for fastening movable jaws. 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.
Tape and spring vise clamps (Clamp)
Tape versions are used by joiners and coopers. This limitation is due to the special design (tensioning mechanism and rigid tape). The tool provides a load over the entire surface, which is good when creating barrels and other round products.
The main advantages of the spring clip include one-handed operation. In shape, it looks like a large clothespin. Among the minuses: the lack of adjustment of the clamping force, a small grip, weakening of parameters during operation.
Pipe clamps
The base of such a clamp includes a tube with a fixed sponge. The second analog moves freely along the base, fastens with a separate stopper, the clamping process is carried out using a screw with a handle. The model is suitable for bonding large area workpieces. As a rule, in such cases, a pair of clamps is taken to ensure uniform pressure on opposite sides of the shields.
