Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Refer to Figures 1 - 5 , a positioning and forming stamping die, including a die body 1. A cavity 14 is provided at the top of the die body 1. The die body 1 is fixed on a bottom plate 23, and a stamping mechanism is connected to the top of the bottom plate 23 through a hydraulic rod 21. The stamping mechanism includes a top plate 18 disposed above the die body 1. Both sides of the bottom of the top plate 18 are connected to the hydraulic rod 21. A punching head 20 is installed on the bottom of the top plate 18 through a mounting seat 19. The punching head 20 matches the cavity 14, and the punching head 20 is located above the cavity 14. During actual use, the workpiece to be processed is placed at a preset position on the top of the die body 1, and then the hydraulic rod 21 can be used to control the punching head 20 to move downwards to cooperate with the cavity 14 to perform stamping processing on the workpiece.

[0028] As Figure 1 and Figure 3As shown in the figure, a support plate 15 is installed at the bottom of one side of the mold body 1. A fixing rod 8 is vertically installed on the top of the support plate 15. A strip-shaped connecting plate 10 is slidably sleeved on the side of the fixing rod 8. At least one supporting plate 13 is installed on one side of the bottom of the strip-shaped connecting plate 10. The supporting plate 13 is arranged in an "L" shape. At least one receiving groove 11 is formed on one side of the mold body 1. One end of the receiving groove 11 communicates with the cavity 14, and one end of the supporting plate 13 extends into the receiving groove 11. During actual use, when the workpiece placed on the top of the mold body 1 is squeezed by the punching head 20, it will move into the cavity 14, and the supporting plate 13 will be driven to move downward during the movement, so that the supporting plate 13 moves into the receiving groove 11.

[0029] As Figure 1 and Figure 3 shown in the figure, a spring 16 is sleeved on the side of the fixing rod 8. The bottom of the spring 16 is fixed on the top of the support plate 15, and the top of the spring 16 is fixed on the bottom of the strip-shaped connecting plate 10. After the stamping is completed and the punching head 20 moves upward, the spring 16 will stretch and push the supporting plate 13 upward to push the formed workpiece out of the cavity 14, facilitating material taking.

[0030] It should be noted that, as Figure 1 shown in the figure, the top of the end of the supporting plate 13 located in the cavity 14 is flush with the bottom of the cavity 14. In this way, during use, the supporting plate 13 will not interfere with the stamping of the workpiece.

[0031] It should be noted that when the supporting plate 13 moves into the receiving groove 11, there is a distance between the bottom of the strip-shaped connecting plate 10 and the connecting block 17. In this way, the supporting plate 13 will not collide with the connecting block 17 during the up and down movement.

[0032] As Figure 1 shown in the figure, two first guide rods 7 are symmetrically installed at both ends of the top of the support plate 15. The tops of the first guide rods 7 slidably penetrate through the strip-shaped connecting plate 10. The strip-shaped connecting plate 10 can be limited by the first guide rods 7 to keep the strip-shaped connecting plate 10 stable;

[0033] As Figure 1 and Figure 4As shown in the figure, a strip-shaped mounting plate 5 is provided on one side of two strip-shaped connecting plates 10. The strip-shaped mounting plate 5 is arranged in an "L" shape, and one side of the strip-shaped mounting plate 5 is fixed on the first guide rod 7 through a connecting block 17. Fixed blocks 3 are installed at both ends of the bottom of the strip-shaped mounting plate 5. A bidirectional lead screw 24 is rotatably connected between the two fixed blocks 3. One end of the bidirectional lead screw 24 is provided with a rotating handle 2. First positioning plates 4 are sleeved on both ends of the bidirectional lead screw 24. One end of the first positioning plate 4 extends to the top of the mold body 1. During actual use, by rotating the bidirectional lead screw 24, the distance between the two first positioning plates 4 can be adjusted so that the distance between the two first positioning plates 4 matches the size of the workpiece to be processed, thus completing the positioning of the workpiece.

[0034] As Figure 1 and Figure 3 shown in the figure, a second positioning plate 12 is installed on the top of each pallet 13. The side surface of the second positioning plate 12 is flush with the side surface of the cavity 14, and the top of the second positioning plate 12 extends above the mold body 1. Through the second positioning plate 12, the workpiece placed on the top of the mold body 1 can be secondarily positioned so that the workpiece can be aligned with the cavity 14.

[0035] Specifically, when the utility model is in use, the staff rotates the rotating handle 2, and the rotating handle 2 drives the bidirectional lead screw 24 to rotate, so that the two first positioning plates 4 move relatively. When the distance between the two first positioning plates 4 matches the size of the workpiece, the staff stops rotating the bidirectional lead screw 24. Then the staff places the workpiece above the mold body 1. The two ends of the workpiece are in contact with the adjacent surfaces of the first positioning plates 4, and one side of the workpiece is in contact with the side surface of the second positioning plate 12, then the positioning is completed. Then the staff controls the punching head 20 to move downward through the hydraulic rod 21, and the punching head 20 presses the workpiece into the cavity 14 for punching processing. During the punching process, the pallet 13 moves downward into the receiving groove 11 under the extrusion of the punching head 20. The pallet 13 drives the strip-shaped connecting plate 10 to move downward, and the spring 16 is compressed. When the punching is completed, the staff controls the punching head 20 to move upward through the hydraulic rod 21. During the upward movement, the spring 16 elongates, pushing the strip-shaped connecting plate 10 upward. The strip-shaped connecting plate 10 drives the pallet 13 upward, pushing the punched workpiece out of the cavity 14, which is convenient for taking the material.

[0036] Furthermore, as Figure 4 and Figure 5 shown in the figure, a connecting plate 25 is installed at the top of one end of each first positioning plate 4 close to the strip-shaped mounting plate 5. A slider 26 is installed on the top of the connecting plate 25. A guide groove 6 is opened at the bottom of the strip-shaped mounting plate 5. The tops of the sliders 26 all extend into the inside of the guide groove 6. With the cooperation of the sliders 26 and the guide groove 6, the first positioning plates 4 can be limited, so that the first positioning plates 4 remain stable.

[0037] Furthermore, asFigure 1 As shown, a anti - detachment ring 9 is installed at the top of the fixed rod 8. When the strip - shaped connecting plate 10 moves to the uppermost position, the top of the strip - shaped connecting plate 10 contacts the bottom of the anti - detachment ring 9. Under the action of the anti - detachment ring 9, the strip - shaped connecting plate 10 can be limited, so that the strip - shaped connecting plate 10 will not be detached from the fixed rod 8 under the elastic force of the spring 16.

[0038] Furthermore, as Figure 2 shown, when the stamping head 20 moves to the lowermost end, there is a gap between the bottom of the mounting seat 19 and the top of the second positioning plate 12. There is a gap between the bottom of the mounting seat 19 and the top of the second positioning plate 12. In this way, when stamping the workpiece, the mounting seat 19 will not collide with the second positioning plate 12.

[0039] Furthermore, as Figure 2 shown, a number of second guide rods 22 are installed at the top edge of the bottom plate 23. The tops of the second guide rods 22 all slide through the top plate 18. The top plate 18 can be positioned through the second guide rods 22, which can keep the top plate 18 stable and avoid the position deviation of the top plate 18 at the same time.

[0040] The above - mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
