Active chip removal mechanism for opposing dies

Abstract

The invention belongs to the field of punching dies for metal and non-metal pipes and plates, and in particular relates to an active chip removal mechanism for a counter punching die, which includes a die base ( 5 ) and mold upper platen ( 6 ); mold upper platen ( 6 ) with the die base ( 5 ) with an elastic recovery mechanism ( 12 ); in the mold base ( 5 ) is fixed with a delay switch base ( 8 ); at the base of the delay switch ( 8 ) is fixed with a delay switch ( 3 ); press the plate on the mold ( 6 ) is fixed with a delay switch touch device ( 2 ); Delay switch touch device ( 2 ) Touch the working end and the delay switch ( 3 ) corresponding to the touch working end; at the base of the delay switch ( 8 ) is fixed with a rigid vent pipe ( 7 ); rigid snorkel ( 7 ) of the exhaust port with the mold base ( 5 ) corresponding to the punching face. The invention has reasonable structure, good versatility and high processing efficiency, and can effectively clean up die base section material waste.

Description

technical field [0001] The invention belongs to the field of punching dies for metal and non-metal pipes and plates, and in particular relates to an active chip removal mechanism for a counter punching die. Background technique [0002] With the advancement of social science and technology, various inventions emerge one after another, and people pay more attention to the inventions that improve production efficiency and liberate productivity. The emergence of pneumatic punching machines has greatly improved production efficiency. It replaces the traditional manual operation, reduces the cumbersome operation procedures and the use of a large number of traditional tools, saves working time, improves the operation accuracy, and also reduces the space occupied by the operation. The operation is safe, convenient and simple, and the failure rate is low. Greatly reduce harsh noise pollution. Pneumatic punch presses use air compressors to convert natural resources into mechanical ...

AI Technical Summary

Problems solved by technology

The generated profile waste will fall and accumulate on the die base, especially for small cylinder punches, the lower part of the die base is the punch cylinder, and chip removal holes cannot be set on the die base, so the waste generated needs to be cleaned irregularly, so that Make the operation interrupted, frequent cleaning will reduce work efficiency

[0005] Secondly, for the structure of the offset mold, the main body of the mold moves downward during punching, and the limit block of the lower punch pin coincides with the base of the mold. When the workload is heavy, the workers will inevitably reduce the amount of time on the base of the offset mold because of rushing to work. For the cleaning of profile waste, when the profile waste accumulates on the mold base, it will occupy the movement space of the lower punch limit block, so that the lower punch limit block cannot coincide with the mold base, and the lower punch cannot be lifted in place, and secondary In the case of punching, the quality of punching cannot be guaranteed, and it will also affect the appearance of the profile, and even cause damage to the mold
