Making method of stamping die for ball neck arm forgings

【 Technical field 】

[0001] The utility model relates to a stamping die, which is characterized by a stamping die for a ball neck arm forgings.

【 Background Technology 】

[0002] In the prior art, it is necessary to punch the middle hole on the ball neck forgings with the punching die on the 160 ton closed press, and then remove the ball neck forgings from the 160 ton press, and then transfer them to the 630 ton press to correct the ball neck forgings with the thermal correction die. This process due to first punching and then correction, the middle hole wall is thin, no skin support after correction is out of round, into an oval, can not meet the requirements; If the first correction and then punching, due to the process is too long, the temperature of the middle hole wall and the skin is reduced, after punching the middle hole wall deformation is large, need to be corrected again; And cost two equipment, two operators, single production time is long, low production efficiency and high cost.
