What Are Cutting Pliers?
Pliers are hand tools used to clamp and fix workpieces, or to twist, bend, and cut wire. The shape of the pliers is V-shaped, and usually includes three parts: the handle, the cheek and the mouth.
- There are many types of pliers, and it has a wide range of uses. It is an indispensable hand tool for clamping and cutting workpieces in assembly, repair and installation in various industries. But it has a common basic structure, that is, any hand pliers county consists of pliers head, pin and pliers handle. The basic principle of pliers is to use two levers at one point in the middle to cross-connect them with pins so that the two ends can move relative to each other. As long as the tail end is operated by hand, the other end can pinch the object. In order to reduce the force used by the user during operation, according to the principle of mechanical leverage, the pliers handle is usually longer than the pliers head. This way, a smaller clamping force can be used to obtain a stronger clamping force and meet the requirements for use. [1]
- Pliers can be divided into: twisted type; shear type; clamped type. According to the type, it can be divided into: hydraulic pliers; crimping pliers; hydraulic wire pliers; wire stripping pliers; rechargeable hydraulic cable pliers. According to the shape, it can be divided into: pointed mouth; flat mouth; round mouth; curved mouth; oblique mouth; needle mouth; top cut; wire pliers; flower gill pliers and so on. It can be divided into: DIY, industrial pliers, special pliers, etc. Divided by structure: two gills. Common specifications are: 4.5 "(mini pliers), 5", 6 ", 7", 8 ", 9.5" and so on.
- The main classifications are as follows:
- Pliers generally include wire pliers, needle-nose pliers, and diagonal pliers. It is used to clamp or bend sheet-shaped, cylindrical metal parts and cut wires. Its side edge can also be used to cut fine wires.
- Material: The pliers are made of high quality chrome vanadium steel.
- Forging: Hot forging technology using die forging.
- Heat treatment: Computer controlled heat treatment technology is used to ensure the stability of hardness.
- Surface treatment: surface polishing.
- Features: The cutting edge is subjected to a special heat treatment process to maintain the stability of long-term cutting work.
- Hardness: HRC40-48.
- Shear knife: Meets DIN standards.
- Use pliers with your right hand. With the jaws facing inward, it is easy to control the cutting position. Use your little finger to extend between the two pliers handles to resist the pliers handles.
- The edge of the pliers can be used to cut the rubber or plastic insulation of the flexible wire.
- The edge of the pliers can also be used to cut wires and wires. When cutting No. 8 galvanized iron wire, use a blade to cut back and forth around the surface a few times, and then just pull it slightly, and the wire will break.
- The mouth can also be used to cut hard metal wires such as electric wires and steel wires.
- The insulated plastic tube of the pliers can withstand more than 500V. With it, it can cut the wire with electricity. Avoid littering during use to avoid damaging the insulated plastic tube.
- Never use pliers as a hammer.
- Do not use pliers to cut the double-stranded live wire, it will short circuit.
- When using a pair of pliers to fix the pull wire around the hoop, the pliers teeth clamp the wire and wind it clockwise.
- It is mainly used to cut single and multi-strand wires with thinner wire diameters, bends to single-strand wire joints, and peel plastic insulation.
