[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-5 As shown, the variable diameter wedge mechanism of the automobile roof crossbeam stamping die of this utility model includes a lower stamping die 1. The top of the lower stamping die 1 is provided with an installation groove 3. Two fixing strips 5 are symmetrically arranged inside the installation groove 3. The top of each of the two fixing strips 5 is fixed with an arc-shaped edge 6. An automobile roof beam mold core 4 is detachably fixed between the two fixing strips 5. Multiple stop components 7 that are fixedly connected to the installation groove 3 are equidistantly arranged on the outer sides of the two fixing strips 5. Both ends of the two fixing strips 5 are provided with wedge components that are detachably connected to the installation groove 3.

[0022] Specifically, by setting up the wedge assembly, during the process of the lower stamping die 1 and the upper stamping die closing, the wedge assembly can convert the vertical pressure into the inclined pressure, thereby realizing the flanging treatment of the automobile roof crossbeam stamping and effectively improving the stamping efficiency of the automobile roof crossbeam.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the variable diameter wedge mechanism of the automobile roof crossbeam stamping die of this utility model includes a stop assembly 7 comprising a fixed base 701, an L-shaped frame 702, a triangular stop block 703, and an L-shaped limiting block 704. The fixed base 701 is fixedly connected to the bottom of the mounting groove 3 by screws. The L-shaped frame 702 is fixedly installed on the top of the fixed base 701. The triangular stop block 703 is fixedly installed on the side wall of the L-shaped frame 702. The L-shaped limiting block 704 is fixedly installed on the side of the L-shaped frame 702. The top of the L-shaped limiting block 704 is provided with an inclined surface.

[0024] Specifically, the L-shaped limiting block 704 is symmetrically arranged with the L-shaped frame 702, and through the cooperation of the triangular stop block 703, a limiting groove is formed between the triangular stop block 703 and the L-shaped limiting block 704, which can achieve the limiting and mold-locking effect during the stamping process.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the variable diameter wedge mechanism of the automobile roof crossbeam stamping die of this utility model includes a wedge block 11 and an assembly block 14. The bottom end of the assembly block 14 is fixedly connected to the mounting groove 3 by bolts. The assembly block 14 and the wedge block 11 are slidably connected. The top end of the assembly block 14 is provided with a concave guide groove 16. The bottom end of the wedge block 11 is fixedly provided with a convex slider 15. The convex slider 15 is slidably connected with the corresponding concave guide groove 16. The two sides of the bottom end of the assembly block 14 are provided with symmetrically arranged semi-circular buckle grooves 17. The two sides of the bottom of the mounting groove 3 are fixedly provided with semi-circular buckle blocks. The two semi-circular buckle blocks are engaged and fixed with the corresponding semi-circular buckle grooves 17. The top side of the top of the assembly block 14 is fixedly provided with an integrally connected limit stop block 18. The side of the wedge block 11 is provided with a V-shaped groove 13. The top of the wedge block 11 is fixedly installed with a wedge guide post assembly seat 12. The top of the wedge guide post assembly seat 12 is fixedly connected with a wedge guide post.

[0026] Specifically, by sliding relative to the wedge block 11 and the assembly block 14, when the upper stamping die is closed with the lower stamping die 1, the V-shaped block of the upper die is inserted into the V-groove 13, giving the V-groove 13 an inclined thrust, which pushes the wedge block 11 to slide laterally, thereby converting the vertical pressure into an inclined thrust.

[0027] Both sides of the top of the stamping die 1 are fixed with fixing blocks 9, and the top of each fixing block 9 has two assembly holes 10 for assembling the limiting guide post.

[0028] Specifically, the assembly hole 10 facilitates the assembly of the limiting guide post between the lower stamping die 1 and the upper stamping die.

[0029] Positioning posts 8 can be detachably and fixedly installed at the four corners of the top of the stamping die 1. Multiple U-shaped assembly slots 2 are equidistantly opened on both sides of the bottom of the stamping die 1. The multiple U-shaped assembly slots 2 are fixedly connected to the stamping machine body by gaskets and screws.

[0030] Specifically, the opening of multiple U-shaped assembly slots 2 facilitates the installation between the stamping die 1 and the stamping equipment.

[0031] In specific implementation, when stamping the car roof beam using this stamping die, the lower stamping die 1 and the upper stamping die are first assembled into the stamping machine. During the closing process of the lower stamping die 1 and the upper stamping die, the inclined block of the upper stamping die is pressed into the V-shaped groove 13 opened at the top of the inclined wedge block 11. The inclination of the inclined wedge block 11 pushes the convex slider 15 at the bottom of the inclined wedge block 11 to slide in the concave guide groove 16. When the convex slider 15 slides to the end, it is stopped by the limit stop block 18. At the same time, during the movement of the inclined wedge block 11, it drives the inclined guide post assembly seat 12 to move synchronously. The inclined guide post assembly seat 12 drives the inclined guide post to move horizontally, thereby realizing the inclination force in the stamping direction of the car roof beam and realizing the simultaneous stamping of the flanging of the car roof beam.
