[0015] In the embodiment, before clamping, the elastic element 5 is arranged between the first mounting plate 6 and the upper surface of the lower die 2, so that the top end of the lower punch 3 does not extend into the side of the first mounting plate 6 facing the upper die 1. In use, the worker places the automobile seat angle adjuster on the first mounting plate 6, then fixes the seat angle adjuster by the lock, and then inserts the inner support rod 9 into the tubular part of the seat angle adjuster 28 through the telescopic link 8, and then clamps the upper die 1 and the lower die 2, and the upper punch 4 and the lower punch 3 jointly extrude the circumferential surface of the tubular part of the seat angle adjuster 28, so as to extrude the recess 29 on the circumferential surface of the tubular part of the seat angle adjuster 28. Since the two ends of the first gully 10 and the second gully 11 extend outside the inner support rod 9, the inner support rod 9 can still be pulled out of the tubular part of the seat angle adjuster 28 after the recess 29 is extruded. The inner support rod 9 is arranged to prevent the tubular part of the seat angle adjuster 28 from deforming during stamping.

[0016] As a preferred mode, the upper surface of the first mounting plate 6 is provided with a product placing block 12 in the area where the lower die 2 cooperates with the upper die 1, the product placing block 12 is provided with a second through hole 13 cooperating with the lower punch 3, the side of the product placing block 12 facing the upper die 1 is provided with a semicircular notch 14, the two ends of the notch 14 extend out of the product placing block 12, the second through hole 13 communicates with the notch 14, the lock is located on one side of the product placing block 12, the inner support rod 9 is located on the other side of the product placing block 12, one end of the inner support rod 9 is fixedly connected with the execution end of the telescopic rod 8, the telescopic rod 8 is located on the side of the inner support rod 9 away from the product placing block 12, the connecting line segment between the product placing block 12 and the lock is parallel to the length line of the notch 14, the axis of the inner support rod 9 passes through the center of the virtual circle where the cross section of the notch 14 is located, and the telescopic rod 8 is parallel to the inner support rod 9. After such arrangement, the notch 14 is used to assist in preventing the tubular part of the seat angle adjuster 28 from being deformed and to position the tubular part. When stamping, the upper die 1 cooperates with the lower die 2, and the lower punch 3 extends into the notch 14 to extrude the circumferential surface of the tubular part of the seat angle adjuster 28.

[0017] As a preferred mode, the lock comprises a first air cylinder 15, a first U-shaped block 16, a second U-shaped block 17, and a third U-shaped block 18. A gap is preset between the first U-shaped block 16 and the second U-shaped block 17. The third U-shaped block 18 is located on the side of the second U-shaped block 17 away from the first U-shaped block 16. The third U-shaped block 18 is located on the side of the second U-shaped block 17 facing the area where the upper die 1 cooperates with the lower die 2. The projections of the U shapes of the first U-shaped block 16, the second U-shaped block 17, and the third U-shaped block 18 on the plane perpendicular to the axis of the telescopic rod 8 coincide. The piston rod of the first air cylinder 15 is parallel to the telescopic rod 8. A preset distance is provided between the piston rod of the first air cylinder 15 and the first U-shaped block 16.

[0018] Since the tubular part of the seat angle adjuster 28 is further provided with other components radially, and when the tubular part is manufactured, the connecting line segment of the other components to the axis of the tubular part is line segment A, and the connecting line segment of the recess 29 to the axis of the tubular part is line segment B, the included angle between line segment A and line segment B is 90 degrees. Therefore, the lock is used on the lower die 2 to limit the tubular part by locking the other components on the tubular part. The first U-shaped block 16, the second U-shaped block 17, and the third U-shaped block 18 are used to place one end of the tubular part, so that the tubular part rolls on the first mounting plate 6. The piston rod of the first air cylinder 15 is inserted into the positioning hole of the other components on the tubular part to limit the tubular part and the other components on the tubular part.

[0019] As a preferred embodiment, the first mounting plate 6 is spring-loaded onto the upper surface of the lower mold 2. The elastic element 5 is a spring.

[0020] As a preferred embodiment, the lower surface of the upper mold 1 is provided with a second mounting plate 19 via an elastic element. The second mounting plate 19 is provided with a third through hole 20 that mates with the upper punch 4. The lower surface of the second mounting plate 19 is provided with a cover block 21 that mates with the product placement block 12. The cover block 21 is provided with a fourth through hole 22 that mates with the upper punch 4. The lower surface of the cover block 21 is provided with a mating groove 23 with a semi-circular cross-section. When the upper mold 1 and the lower mold 2 are closed, the mating groove 23 covers the slot opening 14, so that the cross-section of the entire structure formed by the mating groove 23 and the slot opening 14 is a circle. With this setup, when not stamping, the upper punch 4 does not extend into the mating groove 23, and the lower punch 3 does not extend into the slot 14. This allows the tubular part to be gripped by the mating groove 23 and the slot 14, enabling the tubular part to be positioned and limited before mold closing. Only then does the upper punch 4 extend into the mating groove 23 to press the circumferential surface of the tubular part, while the lower punch 3 extends into the slot 14 to press the circumferential surface of the tubular part.

[0021] As a preferred embodiment, the distance from any point on the outer circumference of the inner support rod 9, located outside the first groove 10 and the second groove 11, to the central axis of the inner support rod 9 is equal. This arrangement ensures that the portions of the inner support rod 9 located outside the first groove 10 and the second groove 11 can support the inner circumference of the tubular part.

[0022] As a preferred embodiment, the radial sliding connector includes a fixing block 24, a slider 25, and a groove 26. The fixing block 24 is fixedly disposed at the free end of the piston rod of the telescopic rod 8. The side of the fixing block 24 facing away from the piston rod has a vertical groove 26. The slider 25 has a protrusion 27 that mates with the groove 26. One end of the inner support rod 9 is fixedly connected to the side of the slider 25 facing away from the telescopic rod 8. This arrangement allows the inner support rod 9 to slide vertically (radially) relative to the telescopic rod 8. With this design, the inner support rod 9 always moves synchronously with the first mounting plate 6, while the telescopic rod 8 is fixedly mounted on the lower mold 2.

[0023] like Figure 6 As shown, a fixing member is provided on the first mounting plate 6 outside the area where the upper mold 1 and the lower mold 2 are joined. The fixing member has a channel, and the two ends of the inner support rod 9 are slidably connected to the channel.
