[0036] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below in combination with embodiments, but the scope of the utility model claimed is not limited to the following specific embodiments.

[0037] Reference Figure 1 , Figure 2 and Figure 3 A kind of automobile outer door sill angle plate stamping die, including bottom plate 11, top plate 12, lower die plate 15 and upper die plate 14. Bottom plate 11 is fixedly installed with guide column 13, top plate 12 is slidably connected with guide column 13, upper die plate 14 is fixedly connected with top plate 12, and upper die plate 14 and lower die plate 15 are located between top plate 12 and bottom plate 11. Bottom plate 11 is installed on workbench, top plate 12 is connected with press, workpiece is placed between lower die plate 15 and upper die plate 14, top plate 12 and upper die plate 14 are driven to move downwards by press and workpiece is clamped by upper die plate 14 and lower die plate 15, workpiece is extruded into die groove 17 by lower punch 16, and stamping forming processing is realized.

[0038] Bottom plate 11 is fixedly connected with punching punch 21, lower die plate 15 is provided with through hole 22 for punching punch 21 to pass through, upper die plate 14 is fixedly installed with punching die 23, punching die 23 is provided with die hole 24 matched with punching punch 21, lower die plate 15 is fixedly installed with lower punch 16, and upper die plate 14 is provided with die groove 17 matched with lower punch 16.

[0039] The elastic supporting block 31 is arranged between the bottom plate 11 and the lower die plate 15, and the sum of the thickness of the elastic supporting block 31 and the thickness of the lower die plate 15 is equal to the length of the punching convex die 21. The lower surface of the upper die plate 14 is flush with the lower surface of the punching concave die 23. The punching convex die 21 is sleeved with an elastic supporting sleeve 34, and the length of the elastic supporting sleeve 34 is equal to the thickness of the elastic supporting block 31. The elastic supporting sleeve 34 supports the lower die plate 15 at the punching convex die 21, further preventing the lower die plate 15 from moving downward accidentally when the workpiece is pressed into the concave die groove 17, and improving the reliability. The elastic supporting sleeve 34 and the elastic supporting block 31 support the lower die plate 15 at different positions respectively, improving the stability of the lower die plate 15. The elastic supporting block 31 and the elastic supporting sleeve 34 are made of polyurethane. The supporting force provided by the elastic supporting block 31 on the lower die plate 15 is greater than the maximum pressure required for pressing the workpiece into the concave die groove 17, and is less than the maximum pressure applied by the press on the top plate 12. When the press drives the top plate 12 and the upper die plate 14 to stamp the workpiece, the workpiece is first pressed into the concave die, and after the workpiece is attached to the concave die groove 17, the elastic supporting block 31 and the elastic supporting sleeve 34 are deformed and the lower die plate 15 moves downward.

[0040] The bottom plate 11 is fixedly connected with a positioning block 32, and the lower surface of the elastic supporting block 31 cooperates with the positioning block 32. The positioning block 32 and the elastic supporting block 31 are clamped together to prevent the elastic supporting block 31 from sliding on the bottom plate 11, and to position the lower end of the elastic supporting block 31. The lower die plate 15 is fixedly connected with a positioning plate 33, and the upper surface of the elastic supporting block 31 cooperates with the positioning plate 33. The positioning plate 33 and the elastic supporting block 31 are clamped together to prevent the elastic supporting block 31 from sliding relative to the lower die plate 15, and to position the upper end of the elastic supporting block 31.

[0041] The bottom plate 11 is fixedly connected with a limiting plate 41, and the limiting plate 41 and the lower die plate 15 are provided with a movable gap 42. The limiting plate 41 and the lower die plate 15 are clamped together to limit the lower die plate 15, so that the upper die plate 14 and the lower die plate 15 can clamp the workpiece, and ensure that the workpiece can accurately attach to the concave die groove 17. The limiting plate 41 and the elastic supporting block 31 are provided with a first interval 43, and the limiting plate 41 and the elastic supporting sleeve 34 are provided with a second interval 44. When the lower die plate 15 presses the elastic supporting block 31 and the elastic supporting sleeve 34 downward, the elastic supporting block 31 and the elastic supporting sleeve 34 can have enough space to elastically deform, preventing the elastic supporting block 31 and the elastic supporting sleeve 34 from being clamped by the limiting plate 41.

[0042] The upper die plate 14 is provided with a discharge groove 51 communicating with the die hole 24. The waste produced after the punching die 21 completes the punching process can enter the discharge groove 51 through the die hole 24, preventing the realization of the function of discharging waste and preventing the waste from falling onto the lower die plate 15 to affect the next processing. The punching die 23 is provided with an inclined groove 52 communicating with the discharge groove 51, and the end of the inclined groove 52 away from the die hole 24 is inclined downward. The end of the discharge groove 51 close to the die hole 24 is provided with a guide surface 53, and the upper end of the guide surface 53 is inclined to the inclined groove 52. When the waste in the die hole 24 enters the discharge groove 51, it contacts the guide surface 53 and slides along the inclined direction of the guide surface 53 to the inclined groove 52, so that the waste can enter the inclined groove 52 through the discharge groove 51, and slide out of the upper die plate 14 and the punching die 23 under the action of gravity.

[0043] The punching die 23 is slidably connected with a spring buckle 54 extending into the die hole 24. The end of the spring buckle 54 close to the die hole 24 is provided with an inclined surface 55 abutting against the punching die 21, and the distance between the upper end of the inclined surface 55 and the lower surface of the punching die 23 is less than the maximum height of the active clearance 42. During the process of the punching die 21 entering the die hole 24, the spring buckle 54 can be pushed along the inclined surface 55 to move away from the punching die 21, so that the spring buckle 54 will not block the insertion of the punching die 21 into the die hole 24. When the waste in the discharge groove 51 accidentally falls into the die hole 24, the spring buckle 54 blocks the waste, so that the waste stays in the die hole 24, preventing the waste from falling onto the lower die plate 15, and the waste staying in the die hole 24 can be pushed back into the discharge groove 51 when the punching die 21 is inserted into the die hole 24 next time. The punching die 23 is threadedly connected with a plug 56, and a spring 57 is arranged between the plug 56 and the spring buckle 54. The two ends of the spring 57 are respectively clamped with the end of the spring buckle 54 away from the die hole 24 and the plug 56. After the punching die 21 slides out of the die hole 24, the spring 57 pushes the spring buckle 54 to move towards the die hole 24, so that the spring buckle 54 can extend into the die hole 24 and block the waste in the die hole 24.

[0044] The embodiment has the following advantages:

[0045] Reference Figure 4 During the downward movement of the top plate 12, the workpiece is first clamped and extruded by the lower punch 16 and the upper die plate 14, and at this time the lower die plate 15 is supported by the elastic support block 31, so that the height of the lower die plate 15 remains unchanged, and the workpiece is extruded into the die groove 17 and plastically deformed, so that the profile of the die groove 17 is processed on the workpiece. Reference Figure 5Then the top plate 12 and the upper die plate 14 continue to drive the lower die plate 15 to move downward by the workpiece, and the lower die plate 15 moves downward by the support force of the elastic support block 31, so that the workpiece and the lower die plate 15 are synchronized to move downward, at this time the workpiece is punched by the punching punch 21 fixed with the bottom plate 11 and the workpiece is punched, so that the material contacted with the punching punch 21 is extruded into the die hole 24 and separated from the workpiece, and the workpiece is punched. The press drives the top plate 12 to move upward, so that the upper die plate 14 and the lower die plate 15 are separated, so that the workpiece can be taken out, and the lower die plate 15 returns to the original position under the action of the elastic force of the elastic support block 31, and is reset.

[0046] The workpiece is extruded into the die groove 17, the workpiece is clamped in the die groove 17, which can effectively prevent the workpiece from deviating, so that the workpiece at the punching punch 21 remains stable, and the workpiece is prevented from sliding on the punching punch 21. Since the lower surface of the upper die plate 14 is flush with the lower surface of the punching die 23, the punching die 23 and the lower die plate 15 can clamp the workpiece at the punching punch 21 during the process of pushing the workpiece and the lower die plate 15 downward, which further prevents the workpiece from sliding on the punching punch 21, so that the relative position of the punching position on the workpiece and the material clamped in the die groove 17 can be effectively ensured, the punching precision is effectively improved, and the advantage of high punching precision is achieved.

[0047] According to the disclosure and teaching of the above description, those skilled in the art of the present application can also change and modify the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should fall within the protection scope of the claims of the present application.
