Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] To make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] In the following description, references to "an embodiment", "embodiment", "an example", "example", etc. indicate that the embodiment or example so described may include a specific feature, structure, characteristic, property, element or limit, but not every embodiment or example necessarily includes a specific feature, structure, characteristic, property, element or limit. Additionally, repeated use of the phrase "according to an embodiment of the present application" although possibly referring to the same embodiment does not necessarily refer to the same embodiment.

[0023] In this embodiment: As Figure 1 shown, it includes a positioning plate 93, a lower mold 14, and an upper mold 502. A second slide rail 2 is provided on the lower mold 14, and a second nut 21 is slidably arranged in the second slide rail 2. One side of the positioning plate 93 is movably connected to the lower mold 14 through a positioning screw 8. A second through hole 92 is provided on the other side of the positioning plate 93, and the position of the second through hole 92 is matched with the second slide rail 2. The two sides of the positioning plate 93 are respectively movably connected to the lower mold 14 and the second slide rail 2 to ensure the stability and adjustability of the positioning plate 93. Through the cooperation of the positioning screw 8 and the second slide rail 2, the precise alignment of the positioning plate 93 and the mold is achieved, ensuring the processing accuracy;

[0024] In the middle of the upper end face of the positioning plate 93, a first slide rail 603 is horizontally arranged. A first nut 604 is slidably arranged in the first slide rail 603. A limiting rod 94 is longitudinally arranged on the positioning plate 93. A first through hole 9 is arranged on the right side of the limiting rod 94. The first through hole 9 cooperates with the first slide rail 603. The lower die 14 is correspondingly provided with an upper die 502. The cooperation of the lower die 14 and the upper die 502 completes the shearing operation; through the shear opening 95 of the lower die 14 and the pressing plate 501 of the upper die 502, precise shearing of the material is achieved.

[0025] A shear opening 95 is arranged in the middle of the lower die 14. First positioning holes 4 are respectively arranged at the four corners of the shear opening 95. A first spring 42 is arranged in the first positioning hole 4. The lower end of the first spring 42 is fixedly connected to the first positioning hole 4. First support rods 43 are arranged at the upper ends of the first springs 42 on both sides of the shear opening 95. A connecting plate 3 is arranged at the top of the first support rod 43. Through the cooperation of the first spring 42 and the first support rod 43, the pin 71 of the external load 7 is tightly pressed during the shearing process, and the fixing of the pin 71 is completed to ensure smooth shearing.

A pressing plate 501 is arranged at the upper end of the second support rod 52. The lower die 502 is arranged at the lower end of the pressing plate 501. The width of the upper die 502 matches the interval between the two connecting plates 3, providing additional support and buffering to ensure the stability and shearing accuracy of the upper die 502. The staff drives the upper die 502 to move downward through the pressing plate 501, thereby completing the shearing of the pin 71 of the external load 7.

[0027] A bottom plate 1 is arranged below the lower die 14. Support columns 41 are arranged at the four corners of the lower end of the bottom plate 1, providing support and stability for the entire device to ensure safety during the operation. A discharge port 13 is arranged below the shear opening 95. A collection box 131 is arranged below the discharge port 13, facilitating the automatic dropping and collection of the sheared material and keeping the working environment clean. A handle 1301 is arranged on one side of the collection box 131.

[0028] The longitudinal section of the first slide rail 603 is in the shape of a Chinese character 'zhong'. A first chute 606 is correspondingly arranged in the middle of the first slide rail 603 for the first nut 604. The first chute 606 has a clearance fit with the first nut 604. The longitudinal section of the second slide rail 2 is in the shape of a Chinese character 'zhong'. A second chute 23 is correspondingly arranged in the middle of the second slide rail 2 for the second nut 21. The second chute 23 has a clearance fit with the second nut 21, ensuring smooth sliding of the first nut 604 and the second nut 21 in the slide rail and providing precise positioning and adjustment.

[0029] The front and rear ends of the discharge port 13 are set as V-shaped slopes to guide the sheared materials to slide smoothly into the collection box 131 and prevent material accumulation.

[0030] Workflow: First, according to specific cutting requirements, adjust the position of the positioning plate 93 to meet the specified cutting angle of the pin 71. Loosen the positioning screw 8 on one side of the positioning plate 93 first, then loosen the second screw 22, and adjust the position of the positioning plate 93 along the second slide rail 2 to reach the specified angle. After adjustment, tighten the positioning screw 8 and the second screw 22.

[0031] Then adjust the position of the limit rod 94 to meet the cutting length of the pin 71. Loosen the first screw 605, adjust the limit rod 94 to the specified position, and after adjustment, tighten the second screw 22.

[0032] Place the external load 7 on the positioning plate 93 and press it against the limit rod 94. Then use the pressing plate 501 to push the upper die 502 downward to cooperate with the lower die 14 to complete the shearing. Release the pressing plate 501, take out the external load 7, and repeat the operation.
