An Assembled Rotary Blanking Die

Abstract

Disclosed is an assembled rotary blanking die. The problem that the a reciprocate blanking die is low in work efficiency because of limited motion efficiency is solved. The assembled rotary blanking die comprises a punch component, a matrix component and a gear transmission mechanism. The gear transmission mechanism is a pair of external meshed gears which are equal in number of teeth and number of modes. The punch component and the matrix component are fixedly assembled with central shafts of the two external meshed gears respectively, and the punch component and the matrix component match with each other. Rotation of the punch component and rotation the matrix component can simultaneously achieve blanking and feeding of workpieces. Compared with the conventional reciprocate blanking die, the assembled rotary blanking die has greatly improved production efficiency.

Description

technical field

[0001] The invention relates to a punching die, in particular to an assembled rotary punching die suitable for continuous punching of plates, and belongs to the technical field of metal stamping. Background technique

[0002] The continuous punching of the plate is generally realized by the reciprocating punching die and the stepping feeding mechanism. The punching die performs continuous reciprocating action under the drive of the punching machine. Every time the die reciprocates punching, the stepping feeding mechanism completes a feeding process accordingly. This punching processing method requires that when the punch of the punching die is close to the plate and is ready to punch, the plate must be in a static state relative to the mold, so the feeding mechanism can only start to run after the punch is punched and leaves the plate, and it must The feeding process is completed before the plate is ready to be punched again, and the feeding action is a stepp...
