When stamping the vehicle body longitudinal beam, first place the workpiece on the first die core 104 and start the hydraulic cylinder to drive the top plate 120 and the upper die base 130 and the second die core 140 at its lower end to descend, so that the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109 and the fifth pressing die 110 can be driven to descend. Cooperating with the first die core 104, the workpiece can be stamped and formed in the die groove formed by the combination of the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109 and the fifth pressing die 110. In addition, the presence of the lower die base 102 and the die base rib 103 can increase the stamping depth of the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109 and the fifth pressing die 110 on the workpiece, thereby improving the stamping forming speed and the stamping efficiency of the stamping die.

[0023] Please refer to Figures 2-4 , a plurality of T-shaped grooves 111 are symmetrically arranged at equal intervals on the opposite surfaces of the bottom plate 101 and the top plate 120. A plurality of air vent holes 112 are opened at the upper end of the bottom plate 101. Guide blocks 113 are fixedly connected to both ends of the lower die base 102 and the upper die base 130, and the guide blocks 113 are slidably connected inside the T-shaped grooves 111.

[0024] In a specific embodiment, by controlling the movement of the guide block 113 along the T-shaped groove 111, the position of the workpiece between the bottom plate 101 and the top plate 120 can be adjusted to improve the stamping accuracy.

[0025] Please refer to Figures 2-4 , one end of the die shell 105 is connected with a stabilizing block 121.

[0026] In a specific embodiment, the stabilizing block 121 can initially improve the self-stability of the top plate 120 when descending for stamping.

[0027] Please refer to Figures 2-4 , two stabilizing seats 131 are fixedly connected to both sides of the lower end of the upper die base 130, and stabilizing ribs 132 are fixedly connected to the surfaces of the two stabilizing seats 131.

[0028] In a specific embodiment, the stabilizing seats 131 cooperating with the stabilizing ribs 132 can further improve the stamping stability of the stamping die and improve the stamping quality of the vehicle body longitudinal beam.

[0029] Please refer to Figures 2-4 , the guide block 113 is slidably connected inside the T-shaped groove 111.

[0030] In a specific embodiment, the movement of the guide block 113 along the T-shaped groove 111 can facilitate the precise clamping of the workpiece between the first mold core 104 and the second mold core 140, further improving the stamping quality.

[0032] In a specific embodiment, the fact that the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109, and the fifth pressing die 110 altogether fit with the first mold core 104 can not only improve the stamping forming speed, but also, when one of the structures is damaged, it can be replaced in time, reducing the cost loss.

[0033] Please refer to Figures 2-4 , the bottom plate 101 and the top plate 120 are both made of stainless steel.

[0034] In a specific embodiment, the stainless-steel-made bottom plate 101 and top plate 120 can lower the center of gravity, further improving the overall stability of the stamping die.

[0035] Working principle: When performing a stamping operation on the vehicle body longitudinal beam, first place the workpiece on the first mold core 104, and then start the hydraulic cylinder to drive the top plate 120 and the upper mold base 130 and the second mold core 140 at its lower end to descend, which can drive the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109, and the fifth pressing die 110 to descend. At the same time, in cooperation with the first mold core 104, the workpiece can be stamped and formed in the mold cavity formed by the combination of the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109, and the fifth pressing die 110. The existence of the lower mold base 102 and the mold base rib 103 can increase the stamping depth of the first pressing die 106, the second pressing die 107, the third pressing die 108, the fourth pressing die 109, and the fifth pressing die 110 on the workpiece. Therefore, the stamping forming speed can be increased, so as to improve the stamping efficiency of the stamping die.
