Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
The forging method of of the invention a kind of metal parts processing mold and metal parts as shown in Figures 1 to 5, including with
Lower step:
Step (1): raw material cutting, by Metal Cutting at the blank of required length.
Step (2): the blank of step (1) is put into prefabricated Bending Mould and carries out bending, produced by blank bending
The blank 2 of product.Bending process is cold bending, and cold bending is suitable for the good blank of ductility.Also it can according to need bending process
It is hot bending, it is stronger that hot bending folds the blank come.
