Description

Hidden punch wedge mechanism Technical Field The utility model relates to the technical field of dies, in particular to a hidden punch wedge mechanism. Background In recent years, with the increasingly vigorous competition of the automobile market, various automobile manufacturers aim at covering parts and related stamping parts of automobiles in the direction of developing and researching novel automobile types, and the requirements on the covering parts and the related stamping parts, namely the stamping parts, are higher and higher, and the stamping parts tend to be complicated, high in strength, various and complex in types and unique in shape. In the prior art, the punching of the workpiece in the die cannot be realized under the condition that the angle of the standard wedge is 0-75 degrees, and the standard wedge has great influence on the die space, so that the die cost is increased, and the die cost is increased. The existing workpiece punching can not realize punching if the standard wedge is used but the angle of the standard wedge is 0-75 degrees, even if a part of the workpiece can be laterally punched, the workpiece can have deviation and shake gaps during punching, and accurate punching can not be realized.
