Description

Technical Field

[0001] This utility model relates to the field of stamping die stripping, specifically to a stamping die waste stripping device. Background Technology

[0002] In automobile production, stamping dies are essential key process equipment. Their application spans multiple stages of automobile parts manufacturing, playing a decisive role in automobile quality, cost, and production efficiency. For example, exterior body panels (such as doors, hoods, roofs, fenders, and trunk lids) and interior structural components (such as frames, crossbeams, and longitudinal beams) all rely on stamping dies for forming.

[0003] In the process of blanking, bending, and stretching sheet metal, stamping dies remove excess material from the sheet to obtain the desired part shape and size. This removed material is called scrap. Scrap needs to be removed promptly to prevent it from accumulating inside the die and affecting the stamping operation. To reduce the labor intensity of manual scrap removal, existing technologies include automated scrap removal devices, such as the stamping die scrap removal mechanism (publication number CN212652570U).

[0004] Currently, although existing technologies can automatically remove and clean up waste materials, stamped parts still need to be manually removed and unloaded. When personnel handle the materials, their hands are positioned between the upper and lower dies, posing a safety hazard and resulting in low safety. Utility Model Content

[0005] Therefore, this utility model provides a waste material unloading device for stamping dies, which realizes automatic waste material unloading and automatic stamping part unloading simultaneously, which not only improves processing efficiency, but also improves safety while reducing the labor intensity of personnel.

[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1-5 This utility model provides a waste material removal device for stamping dies, including an upper die base 1 and a lower die base 2 distributed vertically. The bottom end of the upper die base 1 is provided with an upper die 3 that can be raised and lowered. The top end of the lower die base 2 is fixed with a lower die 4 that is adapted to the upper die 3. The four corners of the bottom end of the upper die base 1 are respectively connected to the four corners of the top end of the lower die base 2 with guide structures 11. The guide structure 11 is a commonly used structure in existing dies and will not be described in detail here.

[0029] The bottom end of the lower mold 4 is provided with a waste material unloading component 5 for waste material unloading, specifically, as follows: Figures 3-5As shown, the waste material unloading assembly 5 includes a material holding box 51 fixed to the bottom end of the lower mold base 2. The lower mold base 2 has a material dropping hole 12 that passes through the lower mold base 2. The material dropping hole 12 is connected to the mold cavity of the lower mold 4 and the interior of the material holding box 51. A push plate 52 is slidably provided inside the material holding box 51. An electric push rod 53 for driving the push plate 52 to move is fixed on one side of the material holding box 51.

[0030] The material container 51 has an opening on the side away from the electric push rod 53. A base 8 is fixed to the bottom of the material container 51. The top of the base 8 near the opening of the material container 51 is machined into an inclined surface. Baffles 9 are fixed on both the front and rear sides of the top of the base 8 in front of the inclined surface. The baffles 9 are used to block the waste material that comes off the inclined surface of the base 8 and prevent the waste material from falling from the front and rear sides of the inclined surface.

[0031] The stamped part is placed on the lower die 4. The upper die base 1 is driven to descend by hydraulic cylinders and other driving equipment, which in turn drives the upper die 3 to descend and stamp the stamped part. The stamped waste material falls into the material collection box 51 through the material drop hole 12. Then, the electric push rod 53 drives the push plate 52 to move, which can push the waste material in the material collection box 51 to the inclined surface of the base 8 and discharge it from the inclined surface of the base 8. In actual use, a conveyor can be placed on the side of the material collection box 51 near the inclined surface of the base 8. The waste material is guided to the conveyor from the inclined surface and then transported out by the conveyor, realizing automatic waste material removal, avoiding the accumulation of waste material in the mold, affecting the mold stamping operation, and with high material removal efficiency.

[0032] Next, as Figures 1-4 As shown, a stamping part stripping assembly 6 for stripping stamped parts is provided on one side of the top of the lower die 4. The stamping part stripping assembly 6 includes a pusher plate 61 located on one side of the top of the lower die 4. A push rod 62 is fixed to the front end of the pusher plate 61, and a guide rod 63 is fixed to the rear end of the pusher plate 61. The end of the guide rod 63 away from the pusher plate 61 is slidably connected to the rear end of the lower die base 2 through a slide rail, so as to facilitate the pusher plate 61 to slide on the top surface of the lower die 4.

[0033] A fixing block 13 is fixed on one side of the rear end of the lower mold base 2, and a spring 14 is connected between the guide rod 63 and the fixing block 13 to facilitate the reset of the push plate 61 after it moves.

[0034] A drive component 7 is provided between the waste material unloading assembly 5 and the stamping part unloading assembly 6. The drive component 7 includes a rotating rod 71 located on the front side of the material holding box 51 and the lower die base 2. The rotating rod 71 is rotatably connected to the front end of the material holding box 51 via a rotating shaft.

[0035] The front end of the push plate 52 is fixed with a slide rod 54, the front end of the material container 51 is provided with a slide groove 55, the slide rod 54 extends through the slide groove 55 and out of the front end of the material container 51, one end of the rotating rod 71 is located at the bottom of the slide rod 54, and the other end of the rotating rod 71 is located at the bottom of the push rod 62.

[0036] The lower die 4 is fixed with a guide groove 10 at the end away from the pusher plate 61. The pusher plate 61 pushes the stamped part on the lower die 4 onto the guide groove 10, and then it is discharged from the guide groove 10.

[0037] While the electric push rod 53 drives the push plate 52 to move to the right to remove waste material, the slide rod 54 on the push plate 52 moves to the right along the slide groove 55. The slide rod 54 drives the rotating rod 71 to rotate counterclockwise, causing the other end of the rotating rod 71 to push the push rod 62 to the left, thereby driving the push plate 61 to move to the left along the top surface of the lower die 4. At the same time, it drives the guide rod 63 to move to the left and stretch the spring 14. The push plate 61 pushes the stamped part after being stamped at the top of the lower die 4 onto the guide groove 10. In actual use, a conveyor can be placed on the side of the material box 51 away from the inclined surface of the base 8. The conveyor is located at the bottom of the guide groove 10, and the stamped part is guided to the conveyor by the guide groove 10 and then conveyed out by the conveyor. After the push plate 52 finishes pushing the material, the electric push rod 53 drives the push plate 52 to reset, and the push plate 61 resets under the elastic force of the spring 14, thereby pushing the rotating rod 71 to rotate back to reset.

[0038] This invention enables automatic unloading of stamped parts after stamping, improving processing efficiency. Furthermore, since there is no need for manual handling of the stamped parts, it reduces labor intensity and improves safety.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
