There are many types of pliers with a wide range of uses. They are essential hand tools for gripping and shearing workpieces in various industrial assemblies, machine repairs, and installation. A smaller force can be used to generate a larger clamping force to assist in the completion of the operation. Here are some commonly used pliers tools.


1、 Pipe wrench

Pipe tongs refer to tools used to clamp and rotate steel pipes, which complete the connection between pipes by twisting them. Pay attention to the selection of specifications when using; The jaw opening is equal to the diameter of the workpiece; Use force after the tong head bites the workpiece tightly to avoid slipping; Apply force within the allowable strength of the pipe wrench to keep the tong teeth and adjusting ring clean. Before use, check whether the fixing pins are firm, and whether there are cracks in the tong head and handle. If there are cracks, they cannot be used. After use, clean it in time, apply anti rust oil, and place it in a suitable place.

2、 Pressure clamp

The pressure clamp mainly consists of a base, a column, a rotating arm, and bolts. It is widely used in boiler pipeline installation engineering to thread and press pipelines. Pressure tongs are commonly used to clamp metal pipes for threading and sawing. Through a rotary pen and screw, it is possible to repair bolts, press pads, turn over pipes, repair inner and outer tires, and perform some helpful maintenance work. When clamping large pipes with pressure tongs, a pipe wrench should be added at the back to prevent slipping and damaging the pipes and jaws; "When clamping pipes, it is not necessary to exert excessive force, and gradually tighten them to prevent them from being flattened or being eaten too deeply by the clamping teeth. When clamping long pipes, a tripod should be used to support the end of the pipe."; Apply lubricating oil to the screw rod after use.

3、 Wire breaking pliers

A wire cutter is a tool used to cut electric wires or thicker metal wires. Pay attention to the safety distance between the metal part of the clamp head and the charged body during live working; Before using, it is necessary to check whether the insulation of the insulating handle is in good condition. It is not allowed to use a knife edge to simultaneously cut the live wire and the zero wire to avoid short circuit faults. Also, when using pliers, do not overload them, and act according to your ability. Remember not to twist the pliers constantly, which can easily cause tooth breakage and damage. As long as the pliers can leave bite marks, then clamp the steel wire with the teeth of the front jaw of the pliers and gently lift or press it up and down to disconnect.

4、 Keel clamp

Keel clamps are used for the installation of partitions in decoration projects. During the partition construction process, the use of keel clamps to fix the heaven and earth keels and vertical keels can be completed in one step instead of the traditional process. It has the advantages of saving electricity and materials, simple operation, and smooth working surface. When using, it should also be noted that the clamp body and the fixed surface should be kept vertical, and the position of the punching cut should be set at a 45 ° angle between the vertical keel and the bottom surface of the horizontal keel. Then, press the handle of the keel clamp firmly to make the punch penetrate the two layers of keel, until the horizontal keel and the vertical keel fully and firmly engage.

5、 Flat jaw pliers

Flat jaw pliers, also known as machine vises, are a general-purpose fixture suitable for installing small workpieces. They are accessory parts for milling and drilling machines, and are fixed on the workbench of the machine tool to clamp workpieces for cutting. When clamping the workpiece, the tightness should be appropriate, and the handle can only be tightened by hand, without using other tools to apply force; During strong operation, the force should be directed towards the fixed clamp body as much as possible; Knocking operations on the movable clamp body and smooth surfaces are not allowed; Active surfaces such as screw rods and nuts should be regularly cleaned and lubricated to prevent rust.
