[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts. Current stamping dies are mainly composed of a series of components such as upper dies and lower dies. However, most stamping dies do not have protective structures, making it difficult to block flying debris during the stamping process, increasing the risk of injury to operators and leading to a deterioration of the environmental hygiene of the production site. Utility Model Content

[0003] The purpose of this invention is to provide a stamping die with protective function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stamping die with protective function, comprising a lower die body, a fixed column fixedly connected to the upper part of the lower die body, a movable plate fixedly connected to the outside of the fixed column, an upper die body slidably connected inside the movable plate, a worktable provided above the lower die body, upright plates connected to both sides above the lower die body, a connecting block provided inside the lower die body, a protective structure provided inside the connecting block, a sliding groove provided on the side of the connecting block, the protective structure slidably connected in the sliding groove, a snap-fit ​​structure connected to the front of the lower die body, the snap-fit ​​structure snapping into the connecting block, the protective structure comprising a guide rod one, a guide rod two, a Z-shaped toothed plate and a telescopic device, a protective plate fixedly connected to the outside of the guide rod one, a gear one fixedly connected to one end of the guide rod one, a gear two fixedly connected to one end of the guide rod two, and a slider connected to the back of the Z-shaped toothed plate.

[0005] As a further preferred embodiment of this technical solution, a buffer spring is provided under the movable plate, and the upper mold body is connected to the movable plate through the buffer spring.

[0006] As a further preferred embodiment of this technical solution, the protective plate overlaps with the upright plate, the first guide rod is rotatably connected inside the connecting block, the second guide rod is rotatably connected inside the connecting block, and the telescopic device is fixedly connected outside the connecting block.

[0007] As a further preferred embodiment of this technical solution, one end of the telescopic device is connected to the Z-shaped toothed plate, the slider is slidably connected in the groove, the Z-shaped toothed plate meshes with gear one, and the Z-shaped toothed plate meshes with gear two.

[0008] As a further preferred embodiment of this technical solution, the connecting block is connected to T-slots on both sides, the lower mold body is provided with a T-block, the snap-fit ​​structure includes an auxiliary plate, the auxiliary plate is fixedly connected to the front of the lower mold body, and a threaded rod is rotatably connected inside the auxiliary plate.

[0009] As a further preferred embodiment of this technical solution, one end of the threaded rod is fixedly connected to a turntable, and the threaded rod is externally threaded to a mounting plate.

[0010] As a further preferred embodiment of this technical solution, the mounting plate is engaged with the connecting block, and the mounting plate overlaps with the side of the lower mold body.

[0011] This utility model provides a stamping die with protective function, which has the following beneficial effects:

[0012] (1) This utility model sets up a lower mold body, a movable plate, an upper mold body and a vertical plate, a protective structure and a connecting block. The telescopic device applies tension to the Z-shaped tooth plate, and the slider on the back of the Z-shaped tooth plate slides in the groove. Since the Z-shaped tooth plate meshes with gear one and gear two respectively, gear one and gear two will rotate with the movement of the Z-shaped tooth plate. After the protective plate flips with the guide rod one, it will contact the side of the vertical plate. The stamping die enables the two protective plates to achieve the function of rotating synchronously in opposite directions through the cooperation between gear one, gear two and the Z-shaped tooth plate. After the two protective plates contact the vertical plate, they will protect the stamping area, block the flying debris during stamping, reduce the risk of injury to the operator, and ensure the environmental hygiene of the production site.

[0013] (2) By setting a snap-fit ​​structure, the connecting block is snapped with the T-block through the T-slots on both sides. When the connecting block overlaps the upper part of the lower mold body, the threaded rod is rotated by the turntable, and the mounting plate moves on the surface of the threaded rod. When the mounting plate moves, it snaps with the side of the lower mold body and the connecting block, so that the protective structure and the lower mold body can be quickly assembled. This makes it easy to replace or repair the protective structure as a whole, thus ensuring the adaptability of the stamping die. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a stamping die with protective function includes a lower die body 1. A fixed column 2 is fixedly connected to the upper part of the lower die body 1. A movable plate 3 is fixedly connected to the outside of the fixed column 2. An upper die body 4 is slidably connected inside the movable plate 3. A worktable 5 is provided above the lower die body 1. Vertical plates 6 are connected to both sides of the upper part of the lower die body 1. A connecting block 9 is provided inside the lower die body 1. A protective structure 7 is provided inside the connecting block 9. A sliding groove 11 is opened on the side of the connecting block 9. The protective structure 7 slides... Connected within the slide groove 11, the front of the lower mold body 1 is connected to a snap-fit ​​structure 8, which snaps into the connecting block 9. The protective structure 7 includes a guide rod 701, a guide rod 702, a Z-shaped toothed plate 706, and a telescopic device 707. A protective plate 703 is fixedly connected to the outside of the guide rod 701. A gear 704 is fixedly connected to one end of the guide rod 701. A gear 705 is fixedly connected to one end of the guide rod 702. A slider 708 is connected to the back of the Z-shaped toothed plate 706.

[0021] like Figure 1 and Figure 3 As shown, a buffer spring 10 is provided under the movable plate 3. The upper mold body 4 is connected to the movable plate 3 through the buffer spring 10. The protective plate 703 overlaps with the upright plate 6. The first guide rod 701 is rotatably connected in the connecting block 9. The second guide rod 702 is rotatably connected in the connecting block 9. The telescopic device 707 is fixedly connected to the outside of the connecting block 9. One end of the telescopic device 707 is connected to the Z-shaped toothed plate 706. The slider 708 is slidably connected in the slide groove 11. The Z-shaped toothed plate 706 meshes with the first gear 704. The Z-shaped toothed plate 706 meshes with the second gear 705.

[0022] By setting the slide groove 11, when the telescopic device 707 applies a pushing or pulling force to the Z-shaped toothed plate 706, the slider 708 on the back of the Z-shaped toothed plate 706 will slide in the slide groove 11, so that the slide groove 11 plays a certain guiding role in the movement of the Z-shaped toothed plate 706, and avoids the Z-shaped toothed plate 706 from falling off the connecting block 9 when it moves.

[0023] like Figure 2 and Figure 4 As shown, T-slots 13 are connected to both sides of the connecting block 9, and a T-block 12 is provided inside the lower mold body 1. The snap-fit ​​structure 8 includes an auxiliary plate 801, which is fixedly connected to the front of the lower mold body 1. A threaded rod 802 is rotatably connected inside the auxiliary plate 801. A turntable 804 is fixedly connected to one end of the threaded rod 802. An mounting plate 803 is externally threaded onto the threaded rod 802. The mounting plate 803 snaps into the connecting block 9 and overlaps with the side of the lower mold body 1.

[0024] By setting T-block 12 and T-slot 13, when the connecting block 9 is connected to the lower mold body 1, the connecting block 9 will be engaged with the T-block 12 through the T-slot 13 on both sides, so that the T-block 12 and T-slot 13 play a certain positioning role in fixing the connecting block 9, avoiding the phenomenon of the connecting block 9 shifting position during connection, and improving the stability of the connecting block 9 after it is fixed.

[0025] This utility model provides a stamping die with protective function, and its specific working principle is as follows:

[0026] When the stamping die is in use, the connecting block 9 can be engaged with the T-block 12 through the T-slots 13 on both sides. When the connecting block 9 overlaps above the lower die body 1, the turntable 804 drives the threaded rod 802 to rotate. The mounting plate 803 will move on the surface of the threaded rod 802. When the mounting plate 803 moves, it will engage with the sides of the lower die body 1 and the connecting block 9. Then the material is placed in the worktable 5.

[0027] When the stamping die is stamping the material, the telescopic device 707 can apply a pulling force to the Z-shaped toothed plate 706, and the slider 708 on the back of the Z-shaped toothed plate 706 will slide in the slide groove 11. Since the Z-shaped toothed plate 706 has toothed grooves on the lower left side and the upper right side, and the Z-shaped toothed plate 706 meshes with gear 1 704 and gear 2 705 respectively, gear 1 704 and gear 2 705 will rotate as the Z-shaped toothed plate 706 moves. After the protective plate 703 flips with the guide rod 1 701, it will contact the side of the upright plate 6. After the upper die body 4 is pushed, the upper die body 4 will drive the buffer spring 10 to deform when it slides in the moving plate 3. When the upper die body 4 contacts the lower die body 1, it will stamp the material.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
