Description

Stamping mechanism of automatic metal profile stamping machine

technical field

The utility model relates to a metal profile processing machine, in particular to a stamping mechanism of a metal profile automatic stamping machine.

Background technique

Frame-shaped metals are widely used. Taking the framed filter screen of range hood as an example, it includes: a metal frame body and a filter screen set inside the frame body. The metal frame body is bent from metal. Therefore, in Notches need to be punched at the corresponding bends to facilitate the bending. At the same time, in addition to the notches, locks and corners are also stamped according to the field of use of the metal frame. At present, the processing technology of the above-mentioned metal frame is manual stamping, and the metal profile (aluminum bar or steel bar) needs to be divided into multiple processes at different positions and completed on the stamping machine by hand, and it needs to be completed with multiple molds, resulting in Low work efficiency, inaccurate stamping position, high product scrap rate, and many hidden dangers to work safety.

In general, the stamping process of the above metal frame includes 90-degree notch, lock row, clip angle, front chamfered port, and rear chamfered port. The 90-degree notch needs to be stamped 5 times, the clipped corner 2 times, and the other times. , Each stamping needs to be at different positions of the same metal profile, so multiple stamping machines and molds are required to complete a frame. This process brings the following disadvantages: (1) A punching machine can only punch one process, which requires frequent replacement of the process, resulting in low efficiency; The position is inaccurate; (3) Every time a process is replaced, the metal profile needs to be moved to a place. This handling is easy to cause damage to the material, and the scrap rate of solid products is high; (4) People need to grasp the metal profile to operate, which is different from the punching machine. The distance is very close, so it is easy to cause stamping accidents.
