Technical Field
[0001] This utility model belongs to the field of chain production technology, and in particular relates to an adaptive multi-specification chain interface cutting device. Background Technology
[0002] Chain manufacturing involves multiple steps, including material preparation, rust removal, chain weaving, and welding. Taking the manufacturing of mining grade D chains as an example, welding is required during chain weaving. After welding, there will be welded joints on the chain links, which need to be cut off by a shearing device.
[0003] Traditional shearing devices are often designed to handle chains of a specific size or type. This means that different equipment is needed for chains of different specifications. For production lines that need to frequently handle multiple types of chains, tools need to be changed every time the chain specification is changed, which is not only time-consuming but also increases production costs.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0021] Example
[0022] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a plan view (top view) of the shearing device in the embodiment. Figure 2 What is shown is Figure 1 AA section view diagram;
[0023] This device includes:
[0024] The base 10 and the shearing member 40 are disposed on the base 10 and located on one side of the shearing member 40;
[0025] The base 10 has a support 20 on top, and an extension plate 30 is provided on the top of the support 20. A driving component 31 is provided on the extension plate 30. The output end of the driving component 31 faces downward and is connected to a pressure block 32. The driving component 31 drives the pressure block 32 to move longitudinally.
[0026] The bracket 20 is slidably mounted on the base 10. The bracket 20 is close to or away from the shearing member 40. The channel between the bracket 20 and the shearing member 40 is for placing the chain. The pressure block 32 moves downward to press and fix the chain. The shearing member 40 cuts the chain interface.
[0027] The driving component 31 is a hydraulic cylinder or a pneumatic cylinder, which can drive the pressure block 32 to move up and down to achieve the action of pressing the chain; the bracket 20 slidably set on the base 10 makes the channel distance between the bracket 20 and the shearing component 40 adjustable, so as to accommodate chains of different sizes; specifically, the entire chain is placed in the channel between the bracket 20 and the shearing component 40, and then the interfaces of each link of the chain are cut in sequence, with the interface position of the link corresponding to the lower part of the shearing component 40.
[0028] like Figure 1 , Figure 3 As shown, Figure 1 The diagram shown is a plan view (top view) of the shearing device in the embodiment. Figure 3 The diagram shown is a schematic representation of the shearing component in the embodiment (front view).
[0029] The shearing component 40 includes a mounting frame 41 and a shearing frame 42 hinged to the mounting frame 41 at one end, and a cutting blade 43 is rotatably mounted on the shearing frame 42.
[0030] A protective cover 44 is provided on the outside of the cutting blade 43.
[0031] Mounting bracket 41 is used to mount shearing bracket 42. One end of shearing bracket 42 is hinged to mounting bracket 41. The hinged design allows shearing bracket 42 to rotate around the hinge axis, thereby driving cutting blade 43 to approach the interface of the chain to achieve cutting action. Shearing bracket 42 is also equipped with a motor to drive cutting blade 43 to rotate.
[0032] The protective cover 44 is located on the outside of the cutting blade 43, mainly for protection. On the one hand, it can prevent injury caused by flying debris during operation; on the other hand, it can protect the cutting blade 43 from external factors and extend its service life.
[0033] like Figure 1 , Figure 2 , Figure 4 As shown, Figure 1 The diagram shown is a plan view (top view) of the shearing device in the embodiment. Figure 2 What is shown is Figure 1 AA section view diagram; Figure 4 What is shown is Figure 1 Enlarged schematic diagram of the structure at point B;
[0034] The top of the base 10 is symmetrically provided with sliding grooves 21, and the bottom of the bracket 20 is provided with a slider corresponding to the position of the sliding grooves 21. The slider is located in the sliding grooves 21 and slides in cooperation with the sliding grooves 21.
[0035] A fixed rod 22 is provided in the slide groove 21, and the slider is slidably sleeved on the outside of the fixed rod 22 on its side.
[0036] The arrangement of the slide groove 21 and the slider provides a stable sliding adjustment base track for the bracket 20, ensuring that the bracket 20 can move smoothly back and forth along the slide groove 21 to adjust according to different widths of the chain;
[0037] The fixed rod 22 is set in the slide groove 21, and the slider is slidably sleeved on the outside of the fixed rod 22. This not only provides a guiding function, but also increases the stability of the entire structure and prevents the slider from deviating or shaking during the sliding process.
[0038] The top of the base 10 is also symmetrically provided with several insertion holes 23. The insertion holes 23 are arranged at intervals along the length of the slide groove 21 on the side. On both sides of the bracket 20, and corresponding to and close to the insertion holes 23, there are auxiliary blocks 24. The auxiliary blocks 24 are provided with insertion holes 25. After the insertion holes 25 are aligned with any one of the insertion holes 23, the pin 26 is inserted.
[0039] The first socket 23 is arranged at intervals along the length of the slide groove 21 on the base 10. The second socket 25 on the auxiliary block 24 is aligned with any one of the first sockets 23 as needed, and then fixed by the pin 26, thereby firmly locking the bracket 20 in the required position; ensuring that the bracket 20 will not be displaced during use.
[0040] The diameter of the second socket 25 is not less than that of the first socket 23, so that the pin 26 can be inserted into the second socket 25 and the first socket 23 at any corresponding position in sequence.
[0041] Working Principle: In use, firstly, according to the width of the chain to be processed, loosen the pin 26 and slide the bracket 20 to an appropriate position, allowing the chain to be placed in the channel between the bracket 20 and the shearing member 40. After ensuring the chain is properly positioned, reinsert the pin 26, securing the bracket 20 firmly through the insertion holes 23 and 25. Then, activate the drive unit 31, causing the pressure block 32 to move downwards, tightly pressing the chain in the channel between the bracket 20 and the shearing member 40, ensuring the chain does not shift during shearing. Next, rotate the shearing frame 42, causing the cutting blade 43 to cut the interface. After shearing the chain interface, the drive unit 31 drives the pressure block 32 upwards, releasing the chain. The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
