Description

Technical Field

[0001] This utility model relates to the field of stamping dies, specifically a metal spring stamping die. Background Technology

[0002] Metal spring stamping dies are specialized cold stamping dies used to produce metal springs (such as spring sheets, contact sheets, etc.). Their core function is to apply pressure to metal sheets through stamping processes to achieve material cutting, forming, or plastic deformation, ultimately obtaining spring parts that meet dimensional and functional requirements. Existing metal spring stamping dies are inconvenient to remove material after punching the metal springs, which affects the efficiency of stamping operations and limits their use. Furthermore, during stamping, the direct rigid contact between the concave die and the convex die holder can easily damage the concave die, reducing the die's service life.

[0003] To address the aforementioned issues, a metal spring stamping die is disclosed in Chinese Patent Publication No. CN212884433U. This metal spring stamping die, through the arrangement of a first magnetic block, a second magnetic block, a first mounting groove, a second mounting groove, and a push rod, facilitates automatic unloading by utilizing the weight difference of the metal spring before and after stamping, combined with the repulsive force formed by the first and second magnetic blocks. Unloading is relatively convenient and can replace springs, as springs tend to lose elasticity after prolonged use. This improves the efficiency of stamping processes and has fewer limitations in application. Furthermore, the auxiliary unloading mechanism allows for quick manual unloading when automatic unloading is not possible.

[0004] While the comparative patent solves the problem that the direct rigid contact between the concave and convex mold fixing seats during stamping can easily damage the concave mold and reduce the service life of the mold, the device can only detach the metal spring from the groove cavity. It cannot automatically load the metal spring after it has been removed from the groove into the collection box. The metal spring still needs to be manually loaded into the collection box, which causes great trouble for the staff.

[0005] Regarding the aforementioned related technologies, the device has the drawback that it can only detach the metal spring from the groove cavity, but cannot automatically load the detached metal spring into the collection box. The metal spring still needs to be manually loaded into the collection box, which causes considerable trouble for the staff. Utility Model Content

[0017] Beneficial effects:

[0018] 1. After the metal spring is stamped by the stamping rod, the cylinder drives the lifting plate to reset, which in turn drives the second connecting rod to reset through the first connecting rod and the rotating ball. The second connecting rod then drives the push plate to move again. The push plate moves on the stamping base, and the stamped metal spring is discharged through the discharge component set inside the stamping base. The metal spring is located at the top of the stamping base, and can then be pushed into the collection box.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a metal spring stamping die, including a machine tool 1 and a collection box 18. A frame 2 is fixedly connected to the top of the machine tool 1. A cylinder 4 is fixedly connected to the inner top wall of the frame 2. A lifting plate 5 is fixedly connected to the bottom of the cylinder 4. A stamping rod 6 is fixedly connected to the bottom of the lifting plate 5. A stamping base 3 is fixedly connected to the top of the machine tool 1. A support block 7 is fixedly connected to one side of the frame 2. A rotating groove is machined on one side of the support block 7. A rotating ball 8 is rotatably connected to the inner wall of the rotating groove. A first connecting rod 9 is fixedly connected to the outer wall of the rotating ball 8. A second connecting rod 11 is fixedly connected to the outer wall of the rotating ball 8. A moving block 12 is slidably sleeved at one end of the second connecting rod 11. A second hinge 13 is fixedly connected to the outer wall of the moving block 12. A pushing component is provided at one end of the second hinge 13.

[0028] One end of the first connecting rod 9 is fixedly connected to the first hinge 10. One side of the first hinge 10 is fixedly connected to one end of the lifting plate 5. When the cylinder 4 is activated, the piston rod of the cylinder 4 moves downward, which in turn drives the lifting plate 5 and the stamping rod 6 to move downward. The stamping rod 6 can then stamp the metal spring sheet inside the stamping base 3.

[0029] The pushing component includes a push plate 14 fixedly connected to one end of the second hinge 13. A slide 15 is provided at the bottom of the push plate 14. A limit rod 16 is fixedly connected to the inner wall of the slide 15. When the second connecting rod 11 rotates, it will drive the push plate 14 to move through the moving block 12 and the second hinge 13, thereby causing the push plate 14 to move.

[0030] A slider 17 is fixedly connected to the top of the stamping base 3. A groove 21 is provided on one side of the slider 17, and the push plate 14 can move on the top of the stamping base 3.

[0031] The limiting rod 16 is slidably sleeved with the slide groove 21, and the outer wall of the slider 17 is slidably connected with the inner wall of the slide 15. The limiting rod 16 can play a limiting role, thereby preventing the push plate 14 from separating from the stamping base 3.

[0032] During use, firstly, cylinder 4 is started, and the piston rod of cylinder 4 moves downward, which in turn drives the lifting plate 5 and the stamping rod 6 to move downward. The lifting plate 5 drives the rotating ball 8 to rotate through the first hinge 10 and the first connecting rod 9, which in turn drives the second connecting rod 11 to rotate. The second connecting rod 11 drives the push plate 14 to move through the moving block 12 and the second hinge 13, which in turn causes the push plate 14 to move and no longer cover the top of the stamping base 3.

[0033] Secondly, the metal spring is placed inside the stamping base 3, and the stamping rod 6 can then stamp the metal spring inside the stamping base 3.

[0034] Finally, after the stamping rod 6 has finished stamping the metal spring, the cylinder 4 drives the lifting plate 5 to reset, which in turn drives the second connecting rod 11 to reset through the first connecting rod 9 and the rotating ball 8. Then, the second connecting rod 11 will drive the push plate 14 to move again. The push plate 14 will move on the stamping base 3. At this time, the stamped metal spring will be discharged through the discharge component set inside the stamping base 3. The metal spring is located at the top of the stamping base 3, and then the stamped metal spring can be pushed into the collection box 18.

[0035] Example 2

[0036] Reference Figure 1-4 In the second embodiment of this utility model, the stamping base 3 is fixedly connected to a second magnetic block 20, and the bottom of the collection box 18 is fixedly connected to a first magnetic block 19. The first magnetic block 19 and the second magnetic block 20 attract each other.

[0037] During use, the collection box 18 can be positioned on top of the machine tool 1 by the mutual attraction between the first magnetic block 19 and the second magnetic block 20, so that the metal fragments can be collected.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
