Description

technical field

[0001] The invention relates to a mold for automobile parts, in particular to a stamping device for a buffer bracket of a rear shock absorber of an automobile. Background technique

[0002] The arc structure of the rear shock absorber buffer bracket for automobiles is complex. Usually, the casting process is used to make the blank, and then the required parts can be obtained by deep processing with a lathe and a drilling machine. It is relatively high, and in the process of lathe machining arc, because the workpiece needs to be clamped multiple times to complete the machining of the entire workpiece, the final product accuracy is not enough. At the same time, this processing technology has low efficiency and high energy consumption. High standard. SUMMARY OF THE INVENTION

[0003] In view of the above deficiencies, the punching device of the automobile rear shock absorber buffer bracket of the present invention can well solve the complex production process...
