The steel plate 18 is placed on the lower die 17 and fixed by a fixing component. When stamping, the fixing component is slowly loosened.

[0034] Referring to Figure 2 and Figure 3 , the output end of the hydraulic cylinder 3 is fixedly connected to a push plate 4. Support plates 5 are fixedly connected to the four corner positions at the bottom of the push plate 4. A groove box 6 is fixedly connected to the bottom of the support plate 5. A sliding column 8 is slidably connected to the bottom of the groove box 6. A damping spring 9 is sleeved outside the sliding column 8, and one end of the damping spring 9 is fixedly connected to the bottom of the groove box 6. A fixing plate 10 is fixedly connected to the bottom of the sliding column 8, and the top of the fixing plate 10 is fixedly connected to the other end of the damping spring 9. A sliding plate 27 is fixedly connected to the top of the sliding column 8, and the sliding plate 27 is slidably connected to the inner wall of the groove box 6. The sliding plate 27 slides on the inner wall of the groove box 6. The sliding plate 27 is limited and controlled by the groove box 6 to protect the die. An installation plate 11 is fixedly connected to the bottom of the fixing plate 10. An upper die 12 is fixedly connected to the bottom of the installation plate 11. The steel plate 18 and the lower die 17 are extruded by the upper die 12 to form an axle housing. The hydraulic cylinder 3 pushes the push plate 4 downward to drive the upper die 12 downward. When the upper die 12 contacts the lower die 17, the steel plate 18 is extruded, the sliding column 8 is moved upward, moves upward on the inner wall of the groove box 6, and the outer damping spring 9 is extruded for buffer protection, so that the sliding plate 27 at the top of the sliding column 8 slides on the inner wall of the groove box 6 for buffer protection, protecting the steel plate 18 and the die at the same time, and avoiding damage to the die due to excessive force.

[0035] Referring to Figure 4 and Figure 5, a fixing component is arranged inside the processing box 1.

By the movement of the racks 23, the sliders 24 slide on the inner walls of the slide grooves 25. The movement of the racks 23 drives the connecting blocks 22 at the front end to move, causing the moving blocks 21 to slide on the inner walls of the guide blocks 20. By the sliding of the connecting blocks 22, the clamping plates 26 at the upper end are driven to move, clamping the steel plate 18, facilitating stamping and preventing the stamping from shifting.

[0036] Working principle: Place the steel plate 18 on the top of the bearing box 16. Drive the gear 19 to rotate through the motor 13. The gear 19 meshes with the racks 23 on the left and right sides, causing the racks 23 to move. By the movement of the racks 23, the sliders 24 slide on the inner walls of the slide grooves 25. The movement of the racks 23 drives the connecting blocks 22 at the front end to move, causing the moving blocks 21 to slide on the inner walls of the guide blocks 20. By the sliding of the connecting blocks 22, the clamping plates 26 at the upper end are driven to move, clamping the steel plate 18, facilitating stamping. The hydraulic cylinder 3 pushes the push plate 4 downward to drive the upper die 12 downward. When the upper die 12 contacts the lower die 17, the steel plate 18 is extruded, causing the sliding column 8 to move upward and move upward inside the groove box 6, extruding the outer damping spring 9 for buffer protection, causing the sliding plate 27 at the top of the sliding column 8 to slide inside the groove box 6 for buffer protection. By extruding the steel plate 18 and the lower die 17 with the upper die 12, a bridge shell is formed.
