Abstract：

The impact of the punch damper stiffness to the equipment base and vibration was analyzed. The development and application of a disc spring damper that has the kind of hard-soft-hard variable stiffness characteristics were described. The shock absorber has four damping columns with C-type disc springs. The spring fixes a multiple set together and laminated plate number is gradually increased. Compared with similar shock absorber, this shock absorber has the advantages of high energy absorption and vibration dampening effect. And the punch equipment foundation vibration was effectively reduled and the increasing of the vibration amplitude of the punching machine was limited. The shock absorber is of low cost and convenient to be used.
