Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a stamping self-resetting inclined wedge. Background Art

[0002] The existing bevel wedges are generally used as standard parts in the mechanism to install stamping parts, and are used to produce products such as stamping and flanging by cooperating with stamping punches, blades, and inserts. The bevel wedge converts the vertical force of the press into horizontal or various angles of force through the mutual transmission of force between its components to achieve the side punching and pressing of sheet products by the mold components. The return method of the slider after stamping in the current bevel wedge mechanism is mainly based on the elastic element being compressed and then rebounding. The elastic element will weaken the compressive strength of the bevel wedge mechanism, and the elastic element will produce elastic fatigue after a certain service life. If the elastic element is fatigued and the slider does not return after stamping, it will damage the mold, posing a safety hazard.

[0003] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content
