[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] The wedge mechanism of a stamping die is a mechanical mechanism that converts vertical motion into horizontal or tilting motion through the combined use of a wedge and a slider.

[0004] However, when the compound wedge mechanism of the stamping die is in use, its elasticity of the return spring will weaken and the return length will decrease due to prolonged use, and it cannot be adjusted. Therefore, the service life of the compound wedge mechanism of the stamping die is relatively low.

[0005] This utility model addresses the above-mentioned problems by providing a composite wedge mechanism for stamping dies with a long service life. Utility Model Content

[0006] The purpose of this utility model is to provide a stamping die composite wedge mechanism with a long service life, in order to solve the problem mentioned in the background art that the stamping die composite wedge mechanism is prone to weakening of elasticity and reduction of reset length due to prolonged use, and is not adjustable, thus resulting in a relatively short service life.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a long-service-life stamping die composite wedge mechanism, comprising a stamping connecting block provided at the bottom of the upper stamping die and a connecting mounting base provided at the bottom of the connecting upper stamping die;

[0008] A guide rail is provided at the bottom of the mounting base;

During the rotation of the connecting threaded rod, the limit moving block will be moved to the left or right through the thread action.

[0012] Preferably, a movable slide rod is provided on the side of the connecting mounting base, and the movable slide rod is installed and connected to the connecting mounting base by a snap-fit ​​method.

[0013] Preferably, a wedge-shaped pressure plate is provided at the outer side of the movable slide bar, and a limiting protrusion is provided at the left end of the wedge-shaped pressure plate.

[0014] Preferably, a connecting stamping die is provided at the bottom of the guide connecting slide rail, and a stamping groove is provided in the connecting stamping die at the side position of the wedge-shaped pressure plate.

[0015] Preferably, a side mounting connecting block is provided at the side position of both the connecting lower die and the connecting upper die, and the side mounting connecting block is provided with a mounting connecting groove.

[0016] Preferably, a bottom contact plate is provided at the side position of the connecting stamping die, the bottom contact plate and the connecting stamping die are an integral structure, and the bottom contact plate is provided with supporting ribs.

[0017] Preferably, an insertion connection groove is provided on the upper side of the connecting stamping die near the corner, and the insertion connection groove is formed by punching a hole in the connecting stamping die.
