What are the technical requirements for gear forging?

Gear forgings, as the name implies, is a kind of gear produced by forging technology. The performance of gear forgings will be more stable, and the damage rate will be reduced a lot during operation. Therefore, the demand for gear forgings is great. Gear forgings are also a kind of forging products. When forging, it needs to be carried out in accordance with the rules, and some hard technical requirements need to be met. Then now xiaobian will introduce the technical requirements of gear forgings.

1. The spare size of gear forgings should meet national standards.



2. Gear forgings should ensure proper forging ratio in forging, and should not be forged with round steel of similar size.



3. Steel billet shall not be forged.



4, the material of gear forgings should be consistent with the material of parts, and the chemical composition should meet the national standards. And issue material list.



5, to ensure the normal forging temperature, not low temperature forging or overburning.



6, forgings should be neat and uniform in shape, and forging defects such as lamination and fracture are not allowed.



7, forgings coarse car to do ultrasonic inspection, gear class shall not exceed φ3 equivalent, other shall not exceed φ4 equivalent. The inspection report shall prevail.



8. Normalize after forging.



9. Write the part number on the forging with paint.



These knowledge is the technical requirements that we need to achieve when we carry out gear forging. From the introduction of this article, we should have a general understanding. You have other places that you do not understand, and you are welcome to consult customer service at any time. Gear forgings will be used in where, its application scope is very wide, can not explain one by one, generally used in all kinds of machinery will be used, learn to correctly use gear forgings can prolong the actual service life.
