Description

Technical Field

[0001] The present application belongs to the technical field of stamping dies, and specifically relates to a stamping die protection device. Background Art

[0002] A stamping machine die is a tool used to deform, cut or form the workpiece during the stamping process. A stamping machine die usually consists of an upper die and a lower die. The upper die and the lower die are installed with an appropriate gap and guide. The upper die is moved downward by impact force to place the workpiece on the lower die, and a certain deformation force is applied to it to complete the stamping process. A buffer protection device is generally provided in the stamping die. The buffer protection device can reduce the impact force and reduce the force on the die by absorbing and releasing energy, so as to protect the die and extend the service life of the die to a certain extent.

[0003] For example, a utility model patent with announcement number CN218903231U discloses a stamping die for mechanical processing, including a stamping machine table, the upper surface of the stamping machine table is fixedly connected with four support columns, the top ends of the four support columns are commonly fixedly connected with a top plate, a cylinder is fixedly installed on the upper surface of the top plate, a stamping rod is fixedly installed on the output end of the cylinder, the bottom end of the stamping rod is fixedly connected with a sliding seat, an upper die is fixedly installed on the bottom surface of the sliding seat, a lower die is arranged below the upper die, four buffer springs are arranged below the lower die, the bottom end of each buffer spring is fixedly connected to the upper surface of the stamping machine table, the device is provided with a buffer spring at the bottom of the lower die, the lower die is connected to the top end of the sliding column, and the connecting plate and the shock absorber cooperate with the sliding column to play a role in buffering the lower die, and at the same time, a shock absorber cylinder is arranged at the bottom of the stamping machine table, and the shock absorber cylinder and the damper cooperate to buffer, thereby reducing the noise during the stamping process of the stamping die.

[0004] However, since there is no guide rod connection between the upper die and the lower die in this device, when the buffer spring is bent and fatigued during long-term use, the position of the lower die will be slightly tilted or offset. This not only affects the accuracy of the upper and lower dies in punching the plate, but also causes wear between the upper and lower dies, reducing the service life of the dies. For this reason, a stamping machine die protection device is provided. Utility Model Content
