The upper mold body 10 has an upper closing stage 11, and the lower mold body 20 has a lower closing stage 21. An upper molding groove 1101 is formed on the upper closing stage 11 of the upper mold body 10. A lower molded projection 2101 is formed on the lower closure station 21 to receive stamped vehicle beam-like components. When the upper mold body 10 moves towards the lower mold body 20 along with the press slide, the vehicle beam-like component located at the lower molding protrusion 2101 is stamped into a corresponding shape.

The upper mold body 10 forms at least one plastic deformation receiving groove 1102 on the upper closing stage 11 at the edge of the upper molding groove 1101. The lower closure station 21 forms a plastic stretch protrusion 2102 at a corresponding position. When the upper mold body 10 moves towards the lower mold body 20, the stamped vehicle beam-like component is plastically deformed after being stamped, and a protrusion 901 is formed at a position corresponding to the plastic deformation receiving groove 1102.

The plastic deformation receiving groove 1102 is formed in the boss surface 1103. The plastic stretch protrusions 2102 are provided on the sinking deck 2103. When the vehicle beam-like component is received in the upper molding groove 1101, the edge portion of the vehicle beam-like component is held on the plastic stretching protrusion 2102 and the sinking deck 2103. When the upper die body 10 is used for stamping the vehicle beam part, the edge part of the vehicle beam part can be drawn once at the transition part between the top surface of the lower closing table 21 and the sinking table surface 2103 and drawn twice at the plastic stretching bulge 2102, so that the edge of the vehicle beam part can be subjected to sufficient plastic deformation, and the subsequent edge rebound of the vehicle beam part is prevented.

In a modified embodiment of the present invention, the upper molding groove 1101, the plastic deformation receiving groove 1102, and the boss surface 1103 are formed on the lower closing stage 21. The upper closing table 11 correspondingly forms the lower molding protrusion 2101, the plastic stretching protrusion 2102 and the sinking platform 2103.

It is worth mentioning that the boss face 1103 is implemented with a section length and width of 20mm and a height of 6 mm. The top and the bottom of the boss face 1103 are provided with rounded corners, and the radius of the rounded corners is 5 mm. The boss face 1103 is 25mm away from the edge of the upper molding groove 1101

More preferably, the manufacturing equipment 100 for the anti-rebound vehicle beam-like component further comprises at least one blank holder 30, wherein the blank holder 30 is arranged on the lower mold body 10 or the upper mold body 10, and when the upper mold body 10 covers the lower mold body 20, the blank holder 30 enables the lower mold body 20 and the upper mold body 10 to be in sealed butt joint based on deformation of the blank holder 30.
