Piers, a handmade tool for clamping, fixed processing workpieces or twisting, bending, cutting metal wire.The shape of the pliers is V -shaped, usually includes three parts: handle, clamping cheeks and tongs.The pliers are generally made of carbon structure steel. First forged and rolled into the shape of the embryo, and then the metal cutting and processing of milling, polishing, and finally performed heat treatment.
What types of pliers are
Piers can be divided into: twist type; shear type; twisted shear type.It can be divided into: hydraulic pliers; pierced clamps; hydraulic wire pliers; tickers; charging hydraulic cable pliers.According to the shape, it can be divided into: sharp mouth; flat mouth; round mouth; curvy mouth; diagonal mouth; needle mouth; top cutting; steel wire pliers; flower gill pliers, etc.It can be divided into: DIY, industrial -grade pliers, special pliers, etc.Divide in the form of structural form: through gills and gills.The normal specifications are: 4.5 "(mini clamp), 5", 6 ", 7", 8 ", 9.5" and so on.
The main classification is as follows:
Steel wire
The wire clamp is a clamping and cutting tool, and its shape is as shown in Figure 1.
The wire tongs are composed of the tip head and the tip handle. The tip head includes the mouth, the tooth mouth, the knife mouth, and the mouth.The role of each part of the pliers is: ① the tooth mouth can be used to tighten or loose nuts; ② the knife mouth can be used to cut the rubber or plastic insulating layer of the soft wire, or it can also be used to cut the wires and wire;Cut off the hard metal wires such as wires, steel wires; ④ The insulation plastic tube of the pliers is more than 500V, and it can carry a charged cutting wire with it.In use, do not throw it around.So as not to damage the insulated plastic tube.The wire tip commonly used by electricians is a variety of specifications such as 150mm, 175mm, 200mm, and 250mm.
Pointed claw
Tip tongs are also called littering, which are mainly used to cut single -stock and multi -share lines with thinning wires, as well as the bending ring of single -stock wire joints, plastic peeling insulation layers, etc. It is also an electrician (especially insider electrician)One of the commonly used tools.It is composed of a pointed, knife mouth, and tong handle.Electricians pliers with pointed clamps have an insulating sleeve with a rated voltage of 500V.Due to the sharp head, the operation method of using a pointed clamp bending wire connection with a narrow space is: first fold the head head to the left, and then tighten the screw to the right.
Piping
One of the tools commonly used by inside electricals, electric motor repair, and instrumentation electricals, are as shown in Figure 2.It is composed of the knife port, pressure line and tong handle.The clamping handle of the threading clamp has an insulating sleeve with a rated working voltage of 500V.
Slip -peeling is suitable for peeling of plastic, rubber insulating wires, and cable core wires.
Pipe Wrenches
Used to tighten or disassemble various pipes, pipe attachments or circular parts.Commonly used tools for pipeline installation and repair.Its embedded can be forged and manufactured.In addition, it is manufactured by aluminum alloy, which is characterized by light weight, light use, and not easy to rust.
Tong
Sometimes the partial tongs are also called oblique pliers.When the cutting point, especially when the welding point is cut off the Internet, the excess wire header and the printed circuit board are too long after the printed circuit board is placed.Plots are also often used to replace general scissors to cut insulating sleeves, nylon tie -tie cards, etc.The polarizer with a length of 160mm and a plastic insulating handle is the most commonly used.
Precautions for Dingzi
① Use pliers to operate with your right hand.Put the clamp into the inside, which is convenient to control the cutting part of the pliers. Use the little finger to the middle of the two pliers to resist the tong handle, and open the piping head.
② The knife mouth of the pliers can be used to cut the rubber or plastic insulating layer of the soft wire.
③ The knife mouth of the pliers can also be used to cut the wire and wire.When cutting the No. 8 galvanized wire, use the blade to cut back and forth a few times, and then just pull it gently, and the iron wire is broken.
④ 用 可以 can also be used to cut off the hard metal wires such as wires and wires.
⑤ The insulation plastic tube of the pliers is more than 500V. With it, it can carry a charged cutting wire.Do not throw it in the use to avoid damage to the insulated plastic tube.
⑥ Do not use the pliers as a hammer.
⑦ Do not use pliers to cut dual -shares with electric wires, which will be short -circuited.
⑧ When fixing the hug with a pliers to fix the pull line, clamp the iron wire with the mouth of the pliers to wrap it in clockwise.
线 Single -stock and multi -stock lines with thinning lines and more wire -shaped wire connectors, bending circles of single -stock wires, and plastic insulation layers.
