Punching die capable of reversing punching direction

Abstract

The invention discloses a punching die capable of reversing the punching direction. The punching die comprises a die holder and a driving block, wherein the die holder is provided with a mounting cavity, and the driving block is located outside the side face of the die holder. A punching female die, a punching male die and two rotating blocks are arranged in the mounting cavity; the punching female die is located between the punching male die and the driving blocks. A concave cavity of the punching concave die faces the punching convex die; the punching male die is sleeved with a pressing plate capable of moving relative to the punching male die. The punching male die and the pressing plate are installed in the fixing base in a sliding mode. Each rotating block is provided with a sliding block, the sliding blocks slide in the sliding grooves of the die base, one end of each sliding block makes press contact with the driving block, the other end of each sliding block makes press contactwith the inner side of one end of the corresponding rotating block, and the inner side of the other end of each rotating block makes press contact with the end face, away from the punching female die, in the fixing base. The punching die is simple and compact in structure and stable in punching.

Description

technical field [0001] The invention relates to a punching die in the field of auto parts production and research, in particular to a punching die that reverses the punching direction. Background technique [0002] With the advancement of science and technology and the increase of labor costs, in order to improve production efficiency and obtain more high-quality products, after automatic punching of automobile body stamping parts, the welding of parts is gradually turned to robots. In order to match welding fixtures and robots, there is such a type of product that is limited by positioning and operating space. The placement of stamping parts cannot allow the cutter to punch from the front. It is necessary to reverse the stamping direction through a certain mechanism to achieve punching. Because, when the stamping is tangentially cut, the lower die cutting knife will be very weak and has no edge strength [0003] In the prior art, a standard or self-made reverse wedge is ge...
