Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-misalignment stamping technology, and in particular to an anti-misalignment stamping forming equipment for hardware connectors. Background Technology
[0002] Hardware connectors are indispensable basic components in fields such as machinery, automobile manufacturing, and electronics. Their processing accuracy directly affects the assembly performance and service life of products. Stamping, as one of the main production processes for hardware connectors, has advantages such as high efficiency, low cost, and suitability for mass production. However, in practical applications, material misalignment during the stamping process has always been a key factor restricting the accuracy and yield of finished products.
[0003] In existing technologies, traditional stamping equipment often employs a relatively simple structure. It typically consists of basic upper and lower die sets, with the upper die set connected to a stamping power source, such as a pressure cylinder or hydraulic device. During operation, the power source drives the upper die set to move rapidly downwards, causing the die mounted on the upper die set to stamp the metal material placed on the lower die set. Positioning relies mainly on simple slots or locating pins to hold the metal material in a specific location. This structural principle is relatively basic, aiming to shape the material through the shape of the die and the stamping power.
[0004] However, existing stamping equipment has a prominent problem: the lack of effective limiting measures for the stamped material. During actual stamping, due to the enormous impact force generated instantaneously, relying solely on slots or locating pins is insufficient to completely secure the metal material. This leads to the material being highly prone to positional displacement during stamping. Once the material's position changes, the dimensional accuracy of the stamped metal connectors will be severely affected, deviating from design requirements. Therefore, a stamping forming device for preventing misalignment of metal connectors is proposed to solve this problem. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a stamping forming equipment for preventing misalignment of hardware connectors, which aims to improve the problem in the prior art that the stamping material cannot be limited, resulting in positional deviations during the stamping process and thus causing deviations in material accuracy.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A stamping forming device for preventing misalignment of hardware connectors includes a support frame, a first hydraulic cylinder fixedly connected to the top of the support frame, an upper mold frame fixedly connected to the output end of the first hydraulic cylinder, a limit component provided inside the upper mold frame, a lower mold frame fixedly connected to the inner wall of the support frame, a mold fixedly connected to the top of the lower mold frame, a clamping plate fixedly connected to the bottom of the upper mold frame, a punch fixedly connected to the bottom of the clamping plate, a force-relieving component provided at the bottom of the clamping plate, and a limit component provided at the top of the lower mold frame.
[0008] The limiting component includes a limiting plate, the bottom of which is disposed on the top of the lower mold frame. A nut is slidably connected inside the limiting plate. A hollow column is disposed at the bottom of the nut. A threaded rod is fixedly connected to the bottom of the nut.

A retaining ball is disposed on the outer wall of the connecting ball. The outer wall of the retaining ball is slidably connected to the inside of the hollow column.
[0009] As a further description of the above technical solution:

A connecting post is provided on the inner wall of the spring, and the outer wall of the connecting post is slidably connected to the inside of the upper mold frame.
[0011] As a further description of the above technical solution:
[0012] The limiting component includes a limiting post, the outer wall of which is slidably connected to the inside of the upper mold frame, one end of which is fixedly connected to the inner wall of the bracket, and the other end of which is fixedly connected to the top of the lower mold frame.
[0013] As a further description of the above technical solution:
[0014] A second hydraulic cylinder is fixedly connected inside the bracket. The outer wall of the second hydraulic cylinder is fixedly connected inside the lower mold frame. A connecting block is fixedly connected to the output end of the second hydraulic cylinder. A first rotating plate is rotatably connected to the side wall of the connecting block.

[0021] As a further description of the above technical solution:
[0022] The third rotating plate sidewall is rotatably connected to the connecting block sidewall, and the bottom of the pressure plate is located at the top of the mold.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, rotating the nut drives the threaded rod to move inside the hollow column, and then the connecting ball drives the locking ball to abut against it, so that the limiting plate side is attached to the side wall of the mold, achieving the effect of limiting the stamping material. This solves the problem that the stamping material cannot be limited, which leads to positional deviations during the stamping process, thus causing deviations in material accuracy. This improves the practicality of the anti-misalignment stamping forming equipment.
[0025] 2. In this utility model, the connecting block is moved by the second hydraulic cylinder. The movement of the connecting block causes the first rotating plate of the side wall to rotate. The rotation of the first rotating plate causes the pressure plate of the side wall to rotate. Then, the rotation of the pressure plate causes the second rotating plate of the side wall to rotate. Next, the second rotating plate is limited by the third rotating plate, pressing the bottom of the pressure plate onto the top of the mold. This achieves the effect of quick mold replacement, solving the problem of long disassembly time and reduced stamping efficiency in the prior art when disassembling the mold, and improving the convenience of the anti-misalignment stamping forming equipment.

[0034] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a hardware connector anti-misalignment stamping forming equipment, including a support 1. The support 1 is usually made of high-strength alloy steel, which has high strength and good toughness and can stably support the various parts of the equipment. A first hydraulic cylinder 2 is fixedly connected to the top of the support 1. An upper mold frame 3 is fixedly connected to the output end of the first hydraulic cylinder 2.

A limit component is provided at the top of the lower mold frame 5.
[0035] The limiting assembly includes a limiting plate 17, which is generally made of aluminum alloy, characterized by low density and high strength. This reduces the overall weight of the equipment while maintaining the limiting function. The bottom of the limiting plate 17 is positioned at the top of the lower mold frame 5. A nut 18 is slidably connected inside the limiting plate 17. The nut 18 is made of brass, which has good wear resistance and self-lubricating properties, allowing it to slide smoothly within the limiting plate 17 and preventing rust. A hollow column 19 is located at the bottom of the nut 18, and a threaded rod 20 is fixedly connected to the bottom of the nut 18. The threaded rod 20 is made of alloy steel, possessing high comprehensive mechanical properties and capable of withstanding large torques, ensuring stability and reliability during adjustment. The outer wall of the threaded rod 20 is threaded into the hollow column 19. One end of the threaded rod 20 is fixedly connected to a connecting ball 21. A retaining ball 22 is provided on the outer wall of the connecting ball 21. The retaining ball 22 and the connecting ball 21 are made of bearing steel and cooperate with the connecting ball 21 to slide inside the hollow column 19, playing a precise limiting role. The outer wall of the retaining ball 22 is slidably connected inside the hollow column 19. The stress-relieving component includes a spring 9. The spring 9 is made of spring steel and has a high elastic limit and fatigue strength. It can play a buffering role when the clamping plate 8 contacts the hollow slot plate 7. The top of the spring 9 is set inside the clamping plate 8. One end of the spring 9 is fixedly connected inside the clamping plate 8. The other end of the spring 9 is fixedly connected to the hollow slot plate 7. A connecting post 23 is provided on the inner wall of the spring 9. The outer wall of the connecting post 23 is slidably connected inside the upper mold frame 3.
[0036] Reference Figure 1 , Figure 3 and Figure 5 The limiting assembly includes a limiting post 4, which is made of alloy steel and has high strength and good guiding performance, ensuring the stability and accuracy of the upper mold frame 3 during sliding. The outer wall of the limiting post 4 is slidably connected to the inside of the upper mold frame 3. One end of the limiting post 4 is fixedly connected to the inner wall of the bracket 1, and the other end is fixedly connected to the top of the lower mold frame 5. A second hydraulic cylinder 11 is fixedly connected inside the bracket 1. The outer wall of the second hydraulic cylinder 11 is fixedly connected to the inside of the lower mold frame 5, and a connecting block 24 is fixedly connected to the output end of the second hydraulic cylinder 11. A first rotating plate 13 is rotatably connected to the side wall of the connecting block 24. A pressure plate 12 is rotatably connected to the side wall of the first rotating plate 13. A connecting frame 16 is fixedly connected to the top of the second hydraulic cylinder 11. The side wall of the connecting frame 16 is set on the side wall of the mold 6. A second rotating plate 14 is rotatably connected to the side wall of the connecting frame 16. A third rotating plate 15 is rotatably connected to the side wall of the second rotating plate 14. The side wall of the second rotating plate 14 is rotatably connected to the side wall of the pressure plate 12. The side wall of the third rotating plate 15 is rotatably connected to the side wall of the connecting block 24. The bottom of the pressure plate 12 is set on the top of the mold 6.
[0037] Working Principle: When using the anti-misalignment stamping forming equipment for hardware connectors, the output end of the first hydraulic cylinder 2 first drives the upper mold frame 3 to slide. The sliding of the upper mold frame 3 drives the bottom clamping plate 8 to slide. Next, the clamping plate 8 moves the bottom towards the top of the mold 6. When the clamping plate 8 moves, it first puts the empty slot plate 7 against the top of the mold 6, and then drives the clamping plate 8 to slide again. Next, the movement of the clamping plate 8 retracts the bottom spring 9. At the same time as the spring 9 retracts, it slides the punch 10 into the inside of the empty slot plate 7 and presses the punch 10 into the inside of the mold 6, achieving the stamping forming effect. Then, by rotating the nut... 18. The nut 18 is driven by force to rotate the threaded rod 20 at the bottom, and the threaded rod 20 rotates inside the hollow column 19. Next, the hollow column 19 drives the connecting ball 21 at the bottom to move linearly inside the hollow column 19. Then, the movement of the connecting ball 21 drives the locking ball 22 on the outer wall to slide, pushing the locking ball 22 out of the hollow column 19 and into the lower mold frame 5. After installation, the side wall of the limiting plate 17 is pressed against the side wall of the mold 6, limiting the stamping material and restricting the stamping material to the top of the mold 6. This restricts the position of the material during the stamping process, achieving the effect of limiting the stamping material.
[0038] Subsequently, the connecting block 24 is moved by the output end of the second hydraulic cylinder 11, and the connecting block 24 moves linearly at the top of the second hydraulic cylinder 11. Next, the movement of the connecting block 24 rotates the first rotating plate 13 on the side wall, and the side wall of the first rotating plate 13 moves circumferentially along the side wall of the connecting block 24. The rotation of the first rotating plate 13 then rotates the pressure plate 12 on the side wall. Simultaneously, a connecting frame 16 is provided at the top of the second hydraulic cylinder 11, and the rotation of the pressure plate 12 rotates the second rotating plate 14 on the side wall. The second rotating plate 14 rotates on the side wall of the connecting frame 16, and the third rotating plate 15 on the side wall rotates as the second rotating plate 14 rotates. The third rotating plate 15 rotates on the side wall of the connecting block 24, and then moves through the connecting block 24. The movement of the connecting block 24 causes the first rotating plate 13 on the side wall to rotate. Due to the design of the connecting frame 16, the movement of the second rotating plate 14 is limited, and then the pressure plate 12 is pressed on the top of the mold 6, achieving the effect of quickly changing the mold 6.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is 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 described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
