Description

A shock absorbing device for stamping die

Technical Field

The utility model relates to the technical field of stamping dies, in particular to a shock absorbing device for a stamping die.

Background Art

Die processing refers to the processing of forming and blanking tools, and also includes shearing and die-cutting dies. Usually, the die consists of two parts: the upper die and the lower die. The steel plate is placed between the upper and lower dies, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the die is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds.

After searching, the utility model patent with Chinese patent publication (announcement) number CN210702037U discloses a shock absorbing device for automobile stamping die processing, which is roughly described as including a base, side panels are symmetrically arranged on both sides of the top of the base, and the top of the side panels is fixedly supported by a frame. When in use, under the thrust of the hydraulic cylinder, the upper die body and the lower die body continue to move downward, so that the entire stamping action is completed in the accommodating groove. Through the design of the spring, it has a good shock absorbing and buffering effect. Through the design of the sound-absorbing structure layer, it can absorb the noise generated by the stamping action. However, the above device still has certain shortcomings. For example, the above device only uses buffer columns and springs for shock absorbing and buffering. The structure of the shock absorbing device is single and traditional. Moreover, because only springs are used, it is possible that the spring reciprocating motion rebounds, the stability is poor, and the shock absorbing effect is not good. For this reason, we propose a shock absorbing device for stamping dies.

The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.

In summary, the working principle and working process of the shock absorbing device for the stamping die are as follows: when in use, the shock absorbing device for the stamping die is first placed at the desired location, and then when the upper die 20 falls on the lower die 3, the lifting plate 2 drives the slider 22 to move in the bottom groove 1, the lifting plate 2 descends, and the damper 7 and the shock absorbing spring 8 buffer and damp the impact force generated by the descent of the lifting plate 2. At the same time, the adjusting rod 14 is also rotated and adjusted between the fixed plate 12 and the slider 15, so that the two sliders 15 can squeeze the shock absorbing spring 2. 17, so as to facilitate the purpose of shock absorption and buffering. Then, if the damper 7, the adjusting rod 14, etc. are damaged, people can open the maintenance door 24, remove the second bolt, and remove the baffle 6, so that the mounting seat 5 and the damper 7, etc. can be taken out. The same is true when removing the mounting plate 10. The block 11 can be directly removed. The present device avoids the use of a connection structure with many bolts and a directly fixed structure, and adopts a detachable connection structure, which is convenient for people to repair and improve the maintenance efficiency of people during maintenance.
