Conveying chainThe processing technology:
1. Quenching: Each part is heated to a certain temperature. In the heat treatment configuration, the heating and storage time is confirmed, and then cooled in different media according to requirements, and the hardness of the parts can be improved.
2. Carburizing, heat treatment is set in the heat treatment, part is heated to a certain temperature, kept for a certain time, and then enters the carbon-containing medium, and the carbon enters the appearance of the part to improve the hardness and wear resistance.
3. Tempering: The part after quenching and quenching is heated, the temperature after heating treatment can be determined, and the temperature is cold after heat preservation. The end of the part can be low quenching hardness, quenching stress and toughness.
4. Abstract: The principle of polymer organic polymerization is accepted. Heat and heat make the film black during heat treatment. It has the characteristics of light resistance, corrosion resistance, rust resistance, low labor intensity, and improved production environment.
5. Shot peening: A punishment for the appearance, the steel ball with a certain diameter must be surface treated to form a small and symmetrical pit to improve the appearance of the chain.
6. Blue: After heating to a certain temperature, the chemical solution is cooled and saponified to make each part appear blue. Finally, the blue method is used to deal with the penalty chain on the surface of the chain, and other anti-rust effects. It is not enough that these chemical solutions will cause a lot of pollution to the environment.
7. Phosphate ester: phosphating at a certain temperature, at a certain temperature, at a certain temperature, so that it forms a phosphating layer in appearance, appearance, color, etc., so that some of it forms black or gray, At the same time, improve the chain to achieve the purpose of corrosion. These phosphate liquids can be recycled and are less polluting to the environment.
8. Electroplating: the main part of receiving electroplating or chemical galvanizing, so that the zinc coating appears on the surface. The zinc coating is both beautiful and rust-proof. Galvanized chains are also practical in the open air.
9. Nickel plating: For the main reason for accepting nickel plating or nickel plating, the nickel plating layer is formed on the surface of the part, and the nickel plating layer is both beautiful and anti-corrosion. Nickel-plated chains are often used in the open air.
10. Oiling: After the conveying chain is oiled, the chain can be guarded for rust and is more radiant.
The accuracy of the chain length shall be measured according to the following requirements:
1. The chain in front has been cleaned
2. Measure the EK chain on the two kinds of sprockets, and support the upper and lower sides of the measuring chain
3. Before applying the 1/3 of the minimum tensile load, the pre-measured chain should be kept at 1 minute
4. When measuring, the measured load is applied to the chain so that both ends of the chain are in tension. The chain should ensure the normal tooth gap of the chain.
5. Measure the center distance of the two sprockets
Measuring chain extension:
1. In order to eliminate the gap of the entire chain, apply a certain tension on the chain
2. In order to reduce the error in the measurement, the measurement is carried out in section 6-10.
3. Measure the inner L1 and outer L2 dimensions of the measurement section to determine the dimension L =(L1 L2)/ 2
4. Find the elongation length of the chain, which is opposite to the use threshold of chain elongation in the previous paragraph
