Pliers have many functions and are used in many industries. The pliers used in different industries are also different. Generally, the more commonly used pliers are:
1. Wire stripper
Wire strippers are commonly used tools for internal electricians, motor repairs, and instrumentation electricians. They are composed of knife edges, crimping ports and clamp handles. They are mainly used for stripping plastic and rubber insulated wires and cable core wires.
2. Wire cutters
Also called a vise, it is a kind of clamp and cutting tool. It is composed of jaws, tooth edges, knife edges, guillotines and pliers handles. It is mostly used to pick up nails or break nails and iron wires.
3. Nozzle pliers
It can be divided into electrical and electronic categories. It is mainly used for cutting injection molding machine products, plastic products, and injection nozzles. It is also suitable for cutting metal products and electronic component pins.
4. Needle-nose pliers
Also known as trimmers, pointed pliers, and pointed pliers. They are composed of pointed tips, knife edges and pliers handles. They are generally made of 45# steel. They are used to cut single and multi-strand wires with thinner diameters and to give orders. Stranded wire joint bending, stripping of plastic insulation layer, etc., can be operated in a relatively small working space.
5. Curved nose pliers
Also called elbow pliers, its function is similar to that of needle-nose pliers without cutting edge, and it is suitable for use in narrow or recessed working spaces.
6. Flat nose pliers
It is a commonly used tool for assembly of metal parts and telecommunications engineering. It is generally used to bend metal sheets and metal filaments to make them into the required shape. In repair work, they are used to install and pull out pins, springs, etc.
7. Diagonal pliers
Mainly used to cut metal wires, flat-nose diagonal pliers are suitable for use in recessed working spaces.
8. Top cutting pliers
End-cutting pliers are similar to diagonal pliers. They are mainly used for cutting steel wires with the cutting edge at the top.
9. Water Pump pliers
The function is similar to a pipe wrench, but it is lighter, smaller and easier to use than a pipe wrench. However, the clamping force is not as good as a pipe wrench. Generally, it is only suitable for household non-professional emergency or simple installation of water pipes.
10. Slip joint pliers
The shape resembles a carp. The opening width of the jaws has two adjustment positions, which can be enlarged or reduced. It is mainly used to clamp round parts. It can also replace small nuts and small bolts with a wrench. It is often used in the auto repair industry.
11. Circlip pliers
Commonly known as circlip pliers, it is a special tool used to install inner and outer circlips, and can also be used to remove circlips. .
12. Vigorous pliers
It is mainly used for clamping parts for riveting, welding, grinding, etc. It can also be used as a wrench. Its characteristic is that the jaws can be locked and generate a large clamping force to prevent the clamped parts from loosening.
Study on Electroplated Diamond Bit Drilling Carbon Brazing Composites
Abstract Carbon brazing composites are prone to delamination, burr, tear and other defects during drilling, which is a typical difficult material. According to the characteristics of carbon brazing composite materials, the electroplated diamond drill bit is taken as the research object. From the drill bit to the research object, the drilling diamond drill bit drilling characteristics are analyzed from the aspects of drilling axial force and drilling outlet quality, and it is compared with the hard alloy twist drill. By comparison, it is concluded that the electroplated diamond bit drills the carbon brazing composite material with less axial force and better drilling quality, which is more suitable for the processing of carbon brazing composite materials; The borehole defect is generated, the axial force of drilling decreases with the increase of the bit rotation speed, and increases with the increase of the diameter of the drill bit. Finally, the empirical formula of the drilling force of the electroplated diamond bit is obtained by the multivariate linear regression method.
