[0002] The main function of a chain is to transmit power. Whether it is a bicycle chain or other types of chains, its core function is to transfer power from one component to another so that mechanical equipment can operate normally. During the production process, a cutting device is used to change the length of the chain as needed.

[0003] Existing chain cutting devices for production involve placing the bicycle chain to be cut on a cutting table, pressing a wrench to push out the locking pin at the chain connection, thus cutting the chain. However, this type of device can only cut specific chain models and cannot cut multiple different chain models, reducing its practicality. Therefore, to address the above problem, we propose a chain cutting device for production. Utility Model Content

[0013] This utility model discloses a chain cutting device for chain production. It includes an installation groove, a compression spring, a handle, a guide post, a sleeve, a locking block, and an electric telescopic rod. When cutting chains of different models, a suitable ejector pin assembly is selected based on the locking post model at the chain connection. After selecting the ejector pin assembly, the handle is pushed outwards, causing the two handles to move back to back. The handle compresses the compression spring, which in turn moves the locking block into the installation groove. Then, the right end of the suitable ejector pin assembly is inserted into the inner left side of the push plate, and the handle is released. At this point, the compression spring provides a reverse force, causing the locking block to move out of the installation groove and into the locking slot of the ejector pin assembly, thus fixing the ejector pin assembly in place.

There are two locking blocks 9, which are located in the locking slots provided at the upper and lower ends of the right side of the ejector assembly 10, respectively. The ejector assembly 10 consists of an ejector pin and a connecting block. The lower outer side of the cutting platform 12 is slidably connected to the upper inner side of the workbench 1. A first hydraulic cylinder 2 is fixedly connected to the upper inner side of the right end of the workbench 1. A push plate 3 is fixedly connected to the left end of the first hydraulic cylinder 2. The upper and lower inner sides of the left end of the push plate 3 are provided with mounting grooves 4 to facilitate the installation of mounting grooves 4, compression springs 5, handles 6, guide posts 7, sleeves 8, locking blocks 9, and electric telescopic rods 11. When it is necessary to cut chains of different models, a suitable ejector pin assembly 10 is selected according to the model of the locking post at the chain connection. After selecting the ejector pin assembly 10, the handle 6 is pushed outward, causing the two handles 6 to move back to back. The handles 6 compress the compression spring 5, and the handles 6 drive the locking block 9 to move, so that the locking block 9 moves into the mounting groove 4. Then, insert the right end of the suitable ejector pin assembly 10 into the inner side of the left end of the push plate 3 and release the handle 6. At this time, the compression spring 5 provides a reverse force, causing the locking block 9 to move out of the mounting slot 4 and into the slot opened in the ejector pin assembly 10, thereby fixing the ejector pin assembly 10 in place. Then, start the first hydraulic cylinder 2, which drives the ejector pin assembly 10 to move to the left, causing the ejector pin assembly 10 to push out the locking pin at the chain connection, thereby cutting the chain. This device can replace different models of ejector pin assemblies 10 as needed, thus cutting chains of different models, improving practicality. At the same time, replacing different models of ejector pin assemblies 10 is simple and can be used immediately; mounting slot 4 An internal compression spring 5 is fixedly connected, and a handle 6 is fixedly connected to the other end of the compression spring 5. A guide post 7 is fixedly connected to the end of the handle 6 near the compression spring 5. A sleeve 8 is fixedly connected inside the mounting groove 4. A locking block 9 is fixedly connected to the end of the handle 6 away from the guide post 7. A pin assembly 10 is provided on the inner side of the left end of the push plate 3. An electric telescopic rod 11 is fixedly connected to the inner side of the upper left part of the worktable 1. A cutting table 12 is fixedly connected to the upper end of the electric telescopic rod 11. A support frame 13 is fixedly connected to the upper end of the cutting table 12. An elastic rubber pad 14 is fixedly connected to the inner side of the left end of the support frame 13. A second hydraulic cylinder 15 is fixedly connected to the inner side of the upper end of the support frame 13. A pressure plate 16 is fixedly connected to the lower end of the second hydraulic cylinder 15.

[0028] In use: The device is powered by an external power source. The chain to be cut is placed on the cutting table 12, with the left end of the chain pressed against the elastic rubber pad 14. The second hydraulic cylinder 15 is activated via an external controller, causing the pressure plate 16 to move downwards, applying pressure to fix the chain. Then, a suitable ejector assembly 10 is selected based on the type of locking pin at the chain connection. After selecting the ejector assembly 10, the handle 6 is pushed outwards, causing the two handles 6 to move back-to-back. The handle 6 drives the guide post 7 to slide into the sleeve 8, simultaneously squeezing the compression spring 5. The handle 6 moves the locking block 9 into the mounting groove 4. Then, the right end of the suitable ejector assembly 10 is inserted into the inner left side of the push plate 3, and the handle 6 is released. At this time, the compression spring 5 provides a reverse force, causing the locking block 9 to move out of the mounting groove 4 and into the locking groove of the ejector assembly 10, thus fixing the ejector assembly 10 in place. The first hydraulic cylinder 2 is activated, which moves the ejector pin assembly 10 to the left, bringing it closer to the chain. Then, the electric telescopic rod 11 is activated, which moves the cutting table 12 and the chain together, so that one end of the locking pin at the chain connection is directly opposite the ejector pin assembly 10. The first hydraulic cylinder 2 then moves the ejector pin assembly 10 to the left, causing it to push out the locking pin at the chain connection, thus cutting the chain. This device can be modified to use different models of ejector pin assemblies 10 to cut different models of chains. Changing the ejector pin assembly 10 is simple and quick. The guide post 7 and the sleeve 8 work together to limit the compression spring 5, reducing wobbling when the handle 6 squeezes the compression spring 5, making the handle 6 move more smoothly. The elastic rubber pad 14 cushions the chain during cutting, reducing pressure damage during chain cutting.
