Embodiment Construction
[0009] Below in conjunction with Fig. 1, describe in detail the specific working situation that the present invention proposes, in figure 1 Among them, a steel wire spring 3 is installed on the guide post 5 on the female mold 1, a silicone spring 2 is installed on the steel wire spring 3, the guide post 5 is connected in the guide hole 6, and the male die 4 is connected with the punch connector 7.
[0010] Connecting the punch connector 7 with the male die 4, the steel wire spring 3 acts as a primary buffer. When the male die 4 touches the silicone spring 2, the silicone spring 2 and the steel wire spring 3 act as a secondary buffer simultaneously.

The invention relates to a double elastic buffering stamping die. A guide column of a cavity die is provided with a steel wire spring on which a silicone spring is arranged, primary buffering is achieved through the steel wire spring, and when a core die is in contact with the silicone spring, the silicone spring and the steel wire spring simultaneously play the role of secondary buffering. Therefore, impacts generated by the stamping die can be fully absorbed in production and burrs and deformation of stamped parts due to impact shock can be effectively eliminated.
Description
technical field [0001] The invention relates to a double elastic cushioning die, which belongs to the technical field of machinery. Background technique [0002] The current punching dies are all primary buffers, which are prone to impact due to insufficient primary buffers during production, resulting in burrs and deformation of punched parts. Contents of the invention [0003] The purpose of the present invention is to provide a double elastic cushioning die, the steel wire spring acts as a primary buffer, and when the male die touches the silicone spring, the silicone spring and the steel wire spring simultaneously play a secondary buffering role. [0004] Its purpose is achieved in this way, a double elastic buffer die is composed of a female mold, a silicone spring, a steel wire spring, a male mold, a guide post, a guide hole, and a punch connector; the guide post on the female die is equipped with a steel wire spring, Silicone springs are installed on the steel wire...
