[0028] Embodiment 1

[0029] Please refer to Figures 1-9, A die - forming slicing anti - interference mechanism, including an upper die base 1 and a lower die base 2. A trimming punch 3 is fixedly installed on the lower surface of the upper die base 1, and a lower die block 4 misaligned with the trimming punch 3 is fixedly installed on the upper surface of the lower die base 2. An upper die pressure plate 5 is arranged below the upper die base 1. A nitrogen spring 20 with an elastic member is arranged between the upper die pressure plate 5 and the upper die base 1. An anti - interference cushion block 6 is fixedly installed on the upper surface of the lower die base 2 on the side of the lower die block 4. A guide block 7 in the shape of a right - angled triangle is fixedly connected to the side of the upper surface of the anti - interference cushion block 6 close to the lower die block 4. A workpiece 8 is placed on the upper surface of the lower die block 4. A support base 9 for supporting the workpiece 8 is arranged on the upper surface of the lower die base 2. An adjustment unit 10 for adjusting the position of the support base 9 is arranged on the upper surface of the lower die base 2. An L - shaped hanging plate 18 is fixedly installed on the lower surface of the upper die base 1, and the hanging plate 18 is used to drive the upper die pressure plate 5 to move upward. An upper die inner guide post 19 is arranged on the upper die pressure plate 5, and the upper end of the upper die inner guide post 19 is slidably connected in the upper die base 1.

[0030] The specific implementation in this embodiment: The inclined surface angle of the above - mentioned guide block 7 is 20°. The cross - section of the guide block 7 is in the shape of a right - angled triangle, and its lower side length is 3 mm. When trimming the workpiece 8, the workpiece 8 is placed on the upper surface of the lower die block 4. The external driving device drives the upper die base 1 to move downward. When the upper die base 1 moves downward, it drives the upper die pressure plate 5 to move downward, and the upper die pressure plate 5 compresses the workpiece 8. The upper die base 1 continues to move downward. At this time, the nitrogen spring 20 is compressed, and the trimming punch 3 trims the workpiece 8. The trimmed workpiece 8 falls and moves to the upper surface of the anti - interference cushion block 6 through the guidance of the guide block 7, realizing a new structure for preventing interference of the cut - off sheet, enabling the manipulator to vertically clamp the product without interfering with the sheet, canceling the trimming process, increasing the material utilization rate, being simple and practical, improving production efficiency, and achieving the goal of cost reduction. When trimming a wider workpiece 8, the workpiece 8 can be supported by the support base 9, and at the same time, the position of the support base 9 can be adjusted through the adjustment unit 10 to improve the applicable range of the overall device. When the upper die pressure plate 5 compresses the workpiece 8 and the upper die base 1 continues to move downward, the upper end of the upper die inner guide post 19 slides in the upper die base 1, and the upper die inner guide post 19 limits the position of the upper die pressure plate 5. When the upper die base 1 moves upward, it drives the upper die pressure plate 5 to move upward through the hanging plate 18.

[0031] Embodiment Two

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 9, This embodiment includes the above - mentioned embodiments, and further includes: The adjusting unit 10 includes a sliding block 11 fixedly connected to the lower side surface of the support base 9. A sliding groove 12 adapted to the sliding block 11 is formed on the upper surface of the lower die base 2. A lead screw 13 with one end extending to the outside is rotatably connected in the sliding groove 12. The lead screw 13 passes through the sliding block 11 and is threadedly connected to the sliding block 11. A limiting ring 14 is threadedly connected to the side surface of the end of the lead screw 13 located outside. A rotating ring 24 is fixedly connected to the end of the lead screw 13 located outside. A rotating rod 25 is rotatably connected to the side surface of the rotating ring 24 away from the lead screw 13.

[0033] The specific implementation in this embodiment: When it is necessary to adjust the position of the support base 9, rotate the rotating ring 24 through the rotating rod 25. The rotating ring 24 drives the lead screw 13 to rotate. The rotation of the lead screw 13 drives the sliding block 11 to slide in the sliding groove 12, thereby adjusting the position of the sliding block 11. After the position of the support base 9 is adjusted, tighten the limiting ring 14 to limit and fix the position of the lead screw 13.

[0034] Embodiment Three

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 8 , This embodiment includes all of the above - mentioned embodiments, and further includes: A moving groove 15 communicating with the outside is formed at the upper end of the support base 9. A positioning block 16 for positioning the workpiece 8 is slidably connected in the moving groove 15. A spiral spring 17 is fixedly connected between the lower side surface of the positioning block 16 and the inner bottom of the moving groove 15. A guiding column 21 is fixedly connected to the inner bottom of the moving groove 15. The spiral spring 17 is sleeved on the side surface of the guiding column 21. A guiding groove 22 adapted to the guiding column 21 is formed on the lower side surface of the positioning block 16. Limiting bars 23 located in the moving groove 15 are fixedly connected to the opposite side surfaces of the positioning block 16.

[0036] The specific implementation in this embodiment: The position of the workpiece 8 can be positioned through the positioning block 16. One side of the workpiece 8 abuts tightly against the side surface of the positioning block 16. When the upper die base 1 is started to move downward, when the upper die pressing plate 5 moves downward, it pushes the positioning block 16 downward. At this time, the spiral spring 17 is compressed. The upper end of the guiding column 21 moves in the guiding groove 22. After the trimming is completed, the upper die pressing plate 5 moves upward. At this time, the tension of the spiral spring 17 pushes the positioning block 16 upward. At the same time, the limiting bars 23 limit the positioning block 16, and the next workpiece 8 can be positioned continuously, which is convenient for positioning and trimming the workpiece 8. The spiral spring 17 is sleeved on the side surface of the guiding column 21 to prevent the spiral spring 17 from deforming radially.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
