Description

Technical Field

[0001] The utility model relates to the technical field of powder alloy forging, in particular to a powder alloy forging heat treatment mechanism. Background Art

[0002] Powder forging usually refers to a forming process in which a preformed blank sintered with powder is heated and then forged into a part in a closed die. It is a new process that combines traditional powder metallurgy with precision forging, and has the advantages of both. Powder forgings with a density close to the theoretical density of the material can be produced, overcoming the disadvantage of low density of ordinary powder metallurgy parts. Some physical and mechanical properties of powder forgings reach or even exceed the level of ordinary forgings, while maintaining the advantages of ordinary powder metallurgy with less or no chips. Through the reasonable design of preforms and the implementation of less or no flash forging, it has the characteristics of precise forming, high material utilization, and low forging energy consumption.

[0003] After the powder alloy is forged into forgings, the forgings need to be heat treated, that is, quenched. However, in the prior art, only one furnace of forgings can be quenched and transferred at the same time, resulting in low work efficiency. Therefore, we have introduced a heat treatment mechanism for powder alloy forgings. Utility Model Content
