Description

Shock absorber valve block stamping device Technical Field The invention relates to the technical field of valve plate stamping, in particular to a valve plate stamping device of a shock absorber. Background The stamping device is an indispensable core technological equipment in the field of mechanical manufacturing, and utilizes a press machine and a die to apply external force to blanks such as plates, strips and the like so as to separate the blanks, thereby obtaining workpieces with required shapes and sizes. As an important basic equipment in modern industrial production systems, stamping devices are widely used in various fields such as automobile manufacturing. In the prior art, when the stamping device performs stamping processing on a special-shaped valve plate (such as a hexagonal valve plate), the stamping head vertically reciprocates downwards to continuously stamp a stamping belt material, so that the forming of the special-shaped valve plate is completed. However, in the punching process, the punching head can only realize up-down linear motion, and cannot be rotationally adjusted along the vertical axis. This limitation of movement results in a larger spacing between adjacent punching locations on the punched strip, such that there is a larger unused area on the strip (as shown in fig. 21). Therefore, the stamping strip material cannot be fully used for processing the special-shaped valve plate, and the waste of materials and the reduction of the utilization rate are caused. A damper valve sheet punching apparatus has been proposed so as to solve the problems set forth in the foregoing.
