Technical Field

[0001] The utility model relates to the technical field of cold heading equipment, in particular to a limiting mechanism for cold heading and pressing equipment. Background Art

[0002] Cold heading equipment is a special equipment for cold heading processing. Its main function is to plastically deform metal materials at room temperature and press the materials into the required shapes and sizes. A limiting mechanism is required when the cold heading equipment is operating. Among them, the "limiting mechanism for cold heading and pressing equipment" disclosed in the publication number: "CN216858092U" has solved the technical drawbacks that the limiting mechanism is prone to looseness and the products are unstable during the processing. However, there are still many defects in the limiting mechanism of similar structures during actual use. For example, the overall mechanism is relatively simple and does not have the function of adjusting according to the specifications of raw materials during operation. As a result, the limiting mechanism can only clamp and limit raw materials of a single specification during use. When cold heading different specifications of raw materials, the limiting mechanism can only be replaced with a matching model, resulting in a high limitation of the limiting mechanism during use. Therefore, we designed a limiting mechanism for cold heading and pressing equipment to solve the above problems. Summary of the Utility Model

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-7 The present utility model provides a technical solution: a limit mechanism for cold heading and pressing equipment, including a locking mechanism 1 and a driving mechanism 2 assembled on the top of the locking mechanism 1. The locking mechanism 1 includes a base 101 and a pressing plate 4. Bottom splints 102 are provided on both sides of the top of the base 101. Bottom sliders 103 are fixedly installed at the bottoms of the two groups of bottom splints 102. Bottom chutes 104 that cooperate with the bottom sliders 103 are provided on both sides of the top of the base 101. Bottom adjusting plates 105 are fixedly installed at the central positions of the bottoms of the two groups of bottom splints 102. Bottom threaded rods 106 that are threadedly connected to the bottom adjusting plates 105 are rotatably installed on both sides of the base 101. Top splints 402 are provided on both sides of the bottom of the pressing plate 4. Top sliders 403 are fixedly installed at the tops of the two groups of top splints 402. Top chutes 404 that cooperate with the top sliders 403 are provided on both sides of the bottom of the pressing plate 4. Top adjusting plates 405 are fixedly installed at the central positions of the tops of the two groups of top splints 402. Top threaded rods 406 that are threadedly connected to the top adjusting plates 405 are rotatably installed on both sides of the pressing plate 4. The driving mechanism 2 includes a mounting frame 201. Two groups of conjugate cams 203 are rotatably installed inside the mounting frame 201. A driving motor 204 with an output end connected to the conjugate cam 203 is fixedly installed on one side of the mounting frame 201.

[0023] Based on the above structure settings, the limiting mechanism for the cold heading press equipment is composed of a locking mechanism 1 and a driving mechanism 2. Among them, the locking mechanism 1 is the raw material clamping and limiting mechanism during the operation of the cold heading machine. With the help of the locking mechanism 1, the raw materials of the cold heading machine can be limited and locked. The driving mechanism 2 is the power mechanism of the mechanism. With the help of the driving mechanism 2, the mechanism can be driven during operation. Specifically, during the working process, the two bottom clamping plates 102 on the top of the base 101 can support and limit the bottom of the raw materials of the cold heading machine. The pressing plate 4 descends, so that the two top clamping plates 402 can press and limit the top of the raw materials of the cold heading machine. Thus, the raw materials during the operation of the cold heading machine can be limited by the bottom clamping plate 102 and the top clamping plate 402, ensuring the stability of the raw materials during the operation of the cold heading machine. The bottom threaded rod 106 can be rotated to cooperate with the bottom adjusting plate 105 to adjust the distance between the two bottom clamping plates 102 during operation. The top threaded rod 406 can be rotated to cooperate with the top adjusting plate 405 to adjust the distance between the two top clamping plates 402 during operation. By adjusting the distance between the two bottom clamping plates 102 and the two top clamping plates 402, the raw materials with different sizes and thicknesses can be clamped, limited and locked, so that it is convenient for the staff to adjust and control the limiting mechanism according to the actual operation situation of the cold heading machine, making the mechanism match the operation mode of the cold heading machine. The bottom slider 103 and the bottom chute 104 can limit the path of the two bottom clamping plates 102 during movement and adjustment, ensuring the stability of the bottom clamping plate 102 during adjustment operation. The top slider 403 and the top chute 404 can limit the path of the top clamping plate 402 during movement and adjustment, ensuring the stability of the top clamping plate 402 during adjustment operation. The mounting frame 201 can rotatably mount the two conjugate cams 203. The driving motor 204 can drive the two conjugate cams 203 to rotate. When the two conjugate cams 203 rotate, they will drive the pressing plate 4 to descend, so that it is convenient for the top clamping plate 402 mounted at the bottom of the pressing plate 4 to press and limit the raw materials of the cold heading machine.

[0024] Furthermore, sleeves 3 are fixedly installed around the top of the base 101. Telescopic rods 301 inserted into the interior of the sleeves 3 are fixedly installed around the bottom of the pressing plate 4. A return spring 302 that elastically supports the telescopic rod 301 is fixedly installed inside the telescopic rod 301. Among them, the sleeves 3 and the telescopic rods 301 can limit the path of the pressing plate 4 during descent, thereby improving the stability of the pressing plate 4 during the descent of the top clamping plate 402. The return spring 302 can elastically support the telescopic rod 301, thereby facilitating the elastic upward reset of the pressing plate 4 and the top clamping plate 402.

[0025] Furthermore, a drive plate 401 which is used in cooperation with the conjugate cam 203 is fixedly installed on the top of the pressing plate 4. Among them, the drive plate 401 can be in contact with the bottom of the conjugate cam 203 during the operation of the conjugate cam 203. By avoiding lubricating oil application on the drive plate 401, the wear of the conjugate cam 203 during operation is reduced, and the smoothness of the conjugate cam 203 when pressing down the pressing plate 4 is improved.

[0026] Furthermore, operating rods 6 are fixedly installed at the outer ends of the two groups of bottom threaded rods 106 and the two groups of top threaded rods 406, and multiple groups of anti-slip convex rods 5 are fixedly installed on the inner walls of the two groups of bottom clamping plates 102 and the two groups of top clamping plates 402. Among them, the operating rods 6 facilitate the rotation operation of the staff when adjusting the bottom threaded rod 106 and the top threaded rod 406 through a suitable tool. The anti-slip convex rods 5 improve the friction force on the inner walls of the bottom clamping plate 102 and the top clamping plate 402, and improve the stability of the bottom clamping plate 102 and the top clamping plate 402 when clamping and limiting the raw materials of the cold heading machine.

[0027] Furthermore, assembly seats 202 are fixedly installed at the tops of both sides of the mounting frame 201. Among them, the assembly seats 202 can install and fix the mounting frame 201 to the cold heading machine, ensuring the convenience of the staff during the installation and later disassembly of the mounting frame 201.

[0028] Furthermore, two groups of fixing plates 107 are fixedly installed on the front and back of the base 101, and fixing holes 108 are formed in the four groups of fixing plates 107. Among them, the fixing plates 107 and the fixing holes 108 can fix and install the base 101 on the cold heading machine through bolts, ensuring the convenience of the installation and later disassembly of the base 101.
