Stamping die for axle rear cover

Abstract

The invention discloses a stamping die for an axle rear cover and belongs to the technical field of axles. The stamping die for the axle rear cover comprises a working table. Two fixing plates and a lower die are arranged above the working table. The lower die is located between the two fixing plates. A connecting plate is fixedly connected between the two fixing plates. A hydraulic cylinder penetrates the connecting plate. A hydraulic rod is arranged below the hydraulic cylinder. A lifting plate is arranged below the hydraulic rod. An upper die is fixedly connected below the lifting plate through bolts. Fixing blocks are arranged on two sides of the upper die correspondingly. Springs are arranged below the two fixing blocks correspondingly. A power switch is arranged on the front surfaceof the working table. According to the stamping die for the axle rear cover, the fixing blocks and springs are arranged; the fixing blocks play a part of installing the springs; the impact force generated when the lower die is pressed by the upper die can be mitigated by the springs; and it is prevented that the lower die is impacted by the upper die for a long time and the service life of the dieis liable to be influenced.

Description

technical field [0001] The invention belongs to the technical field of vehicle axles, and in particular relates to a stamping die for a vehicle rear cover. Background technique [0002] According to different suspension structures, the axle is divided into two types: integral type and disconnected type. When the non-independent suspension is used, the middle part of the axle is a solid or hollow center beam, and this kind of axle is an integral axle; the disconnected axle is a movable joint structure, which is used with an independent suspension. The bridge can be integral, like a huge barbell, and the two ends support the body through the suspension system, so the integral axle usually cooperates with the non-independent suspension; the axle can also be disconnected, like two umbrellas Inserted on both sides of the vehicle body, and then support the vehicle body through the suspension system, so the disconnected axle is used with the independent suspension. [0003] The e...

Problems solved by technology

[0003] The existing axle rear cover stamping die has poor cushioning effect during use. When the upper die is pressed down on the lower die, the service life of the die is easily affected due to the large impact force, and the vibration damping effect of the stamping die is not good. Strong Vibration is easy to affect the calibration of the mold
