Wear-resistant high-hardness insulating ceramic positioning pin

Wear-resistant high-hardness insulating ceramic positioning pin

Positioning pins are most widely used in molds. Including stamping molds, injection molds and so on. Their precision is particularly high, and if it is only fixed by bolts, it will definitely not work, so only positioning pins are used to achieve positioning

The ceramic positioning pin has extremely strong corrosion resistance, and can also be used in strong acid, strong alkali and sea water. At 1100 ℃, the strength and hardness are almost unchanged. Can also be used in non-magnetic and magnetic fields. Electrical insulation. The density is 3.25---3.28g/cm3, light weight, about 60% lighter than the steel ball, which greatly reduces the centrifugal force on the channel when the bearing rotates at high speed and reduces wear. High rigidity, high strength, its hardness is twice as high as bearing steel, and the elastic modulus is about 1/3 higher. The coefficient of linear expansion is 3.2×10-6/K, which is almost 1/4 of the bearing steel, and can withstand the rapid changes in temperature.

There are 5 types of positioning pins:

1. Fixed positioning pins
2. Interchangeable positioning pins
3. Cone positioning pin
4. Cutting edge positioning pin
5. Standard diamond positioning pin

Performance characteristics:
1. The ceramic positioning pin is similar to the ordinary welding positioning pin, but it is made of super-hard silicon nitride ceramic material. The special physical and chemical properties of ceramic materials determine certain special properties of silicon nitride positioning pins. For example, high wear resistance, high hardness, non-conductive, non-magnetic, non-stick welding slag and other excellent properties.
2. Below I will briefly introduce the performance of ceramic materials:
High hardness: the hardness of zirconia is second only to diamond
High wear resistance: High hardness and good red hardness determine that the zirconia positioning pin has excellent wear resistance
High cost performance: the service life of zirconia positioning pins is several times that of ordinary positioning pins

The role of ceramic positioning pins is to limit the free movement of items. Degrees of freedom: When an object is in space, it must have six degrees of freedom, linear movement in the three axes of X Y Z, and rotational movement around X Y Z. Positioning pins are parts that participate in limiting these degrees of freedom. In a mold composed of two or more parts, a pin designed to accurately position the adjacent two parts of the mold. In the spindle positioning, 1) mechanical cam mechanism (2) rough positioning by photoelectric disk method, then a hydraulic or pneumatic positioning pin is inserted into the pin hole or pin groove on the spindle to achieve precise positioning, and the positioning pin exits after the tool change is completed , The spindle starts to rotate.

• Shipbuilding, bridges, large-scale structural facilities
• Lighting industry
• Electronics and electric heating industry

With the development of science and technology and the improvement of manufacturing technology, new varieties continue to appear, and they will be used more and more in the fields of modern industry and modern science.

Ceramic positioning pins can be applied to accessories for special purpose parts of high temperature resistance, corrosion resistance, wear resistance, and high voltage resistance used in industries such as electronics, machinery, chemical industry, metallurgy, textiles, and power.
