[0026] Specifically, the surface of movable rod 25 is provided with torsional spring 26, one end of torsional spring 26 is connected with recessed plate 22, the other end of torsional spring 26 is connected with connecting plate 24, and torsional spring 26 can reset the moving position of recessed plate 22, to facilitate the use of operator.

[0027] As Figures 1 to 4 The surface of punch mechanism 12 is installed with hydraulic rod 27, and the telescopic end of hydraulic rod 27 abuts on the surface of recessed plate 22, so that it is convenient for operator to use.

[0028] Further, the hydraulic rod 27 is provided with a buffer pad 28 at the telescopic end abutting the surface of the groove plate 22, for buffering the force of the hydraulic rod 27.

[0029] It is worth noting that the buffer pad 28 is made of "rubber material".

[0030] As shown in Figures 1 to 4 The stamping stabilizing assembly 3 comprises a stabilizing plate 31, which is symmetrically and slidably connected to the inside of the lower die 13. A abutting rod 32 is slidably connected to the through hole on the surface of the lower die 13. One end of the abutting rod 32 penetrates the lower die 13 and is connected to the stabilizing plate 31. The other end of the abutting rod 32 is provided with an abutting disc 33, which abuts in the groove on the surface of the groove plate 22. The abutting rod 32 drives the stabilizing plate 31 to clamp and stabilize the automobile leaf spring material to be stamped, so as to avoid the position deviation of the automobile leaf spring in the lower die 13 during stamping, thereby affecting the stamping effect of the automobile leaf spring and further improving the stability of the device in use.

[0031] It is worth noting that the surface of the abutting rod 32 is provided with a reset spring 34, one end of which is connected to the stabilizing plate 31, and the other end of which is installed in the inside of the lower die 13. The reset spring 34 can reset the position of the abutting rod 32, so as to realize the release and position stabilization of the stamped automobile leaf spring after the groove plate 22 drives the stamping plate 21 to release the discharge end of the lower die 13.

[0032] Working principle and process: when stamping the automobile leaf spring, first place the automobile leaf spring in the lower die 13 on the stamping table 1. At this time, start the stamping mechanism 12, so that the stamping mechanism 12 drives the upper die to stamp the automobile leaf spring in the lower die 13;

[0033] Before placing the automobile leaf spring in the lower die 13, first start the hydraulic rod 27, so that the telescopic end of the hydraulic rod 27 pushes the groove plate 22. In the process of pushing the groove plate 22, the buffer pad 28 can protect the groove plate 22, thereby buffering the force of the hydraulic rod 27. At this time, the groove plate 22 slides in the inside of the accommodation slot 23 through the movable rod 25 on the connecting plate 24.
