Technical Field

The invention relates to the field of stamping production, in particular to a stamping automatic line connecting operation process layout and a method.

Background

Aiming at the production layout of a stretched part, the stretching process of the part is usually separated from the stamping and forming process at present; the main reason is that the part stretching process generally needs to be oiled, and the working speed of an oil press is slightly slower than that of a punch press; therefore, the drawing step may not be synchronized with the pressing and forming steps.

Currently, many large and medium-sized stamping plants introduce stamping manipulators to solve the problem of process synchronization in order to control the labor manufacturing cost. However, the robot is difficult to perform the connection operation of the drawing process and the stamping and forming processes in the material transfer process, and often two hydraulic machines and two sets of drawing dies are arranged in the drawing process to supply the post-process stamping and forming production, so that the waste of equipment resources is caused, and the manufacturing cost is high.
