[0022] A shearing machine for hardware products that can limit the position of workpieces includes a body 1, fixed blocks 2 are fixedly arranged on both sides of the body 1, a support block 3 is fixedly arranged on the top of the fixed block 2, a hydraulic cylinder 4 is installed on the bottom of the support block 3 through a mounting seat, a cutting assembly 5 is fixedly arranged on the bottom of the hydraulic cylinder 4, limiting blocks 6 are fixedly arranged on both sides of the top of the body 1, a plurality of placement grooves 7 are opened on the two limiting blocks 6 close to one side of the body 1, a roller 8 is movably arranged between the two limiting blocks 6, and a fixing mechanism is arranged between the roller 8 and the placement groove 7.

[0023] Through the above scheme, the workpiece is moved along the top of the body 1 to below the cutting assembly 5, and the workpiece is cut by the cutting assembly 5;

[0024] In this embodiment, preferably, the fixing mechanism includes a spring 9 and a cross bar 10, a spring 9 is fixedly arranged at the bottom end of the plurality of placement slots 7, a cross bar 10 is fixedly arranged at the top end of the spring 9, and the cross bar 10 is externally movably connected to the roller 8 through a rotating shaft;

[0025] Through the above solution, the cross bar 10 drives the roller 8 to press downward through the spring 9, so that the workpiece is pressed by the roller 8 when moving, ensuring that the workpiece will not deviate during cutting, and at the same time, the fixing structure is simple and reduces the cost of the device;

[0026] In this embodiment, preferably, slide grooves 11 are provided on both sides of the top of one side of the body 1 close to the fixed block 2, and a moving block 12 is movably provided inside the slide groove 11, and a limiting rod 13 is fixedly provided at one end of the two slide grooves 11, and a groove 14 is provided at one end of the moving block 12 inside the slide groove 11, and one end of the limiting rod 13 is located inside the groove 14, and a positioning block 15 is fixedly provided at the top of the moving block 12 away from the limiting rod 13. An observation groove 16 is provided on the body 1 above one end of the slide groove 11 close to the limiting rod 13, and a scale 17 is fixedly provided on one side of the observation groove 16 at the top of the body 1;

[0027] Through the above scheme, the positioning block 15 enables the moving block 12 to move when the workpiece moves. At the same time, the moving distance of the moving block 12 can be observed through the observation slot 16, and then the moving distance of the workpiece can be judged by comparing it with the scale 17, and the workpiece is sheared. At the same time, the limit rod 13 allows the moving block 12 to remain stable when moving. At the same time, the moving block 12 is in a U-shaped shape, so that the cut workpiece can fall from the middle of the moving block 12, thereby realizing the recovery of the workpiece.

[0028] In this embodiment, preferably, a pointer 18 is fixedly provided inside the observation slot 16 on one side of the top of the moving block 12;

[0029] Through the above solution, the pointer 18 allows the staff to more accurately judge the moving distance of the workpiece, and when the moving block 12 needs to be reset, the moving block 12 can be reset by turning the pointer 18;

[0030] In this embodiment, preferably, a cutting groove 19 is provided at the top of the body 1 below the cutting assembly 5;

[0031] Through the above solution, the cutting groove 19 enables the cutting assembly 5 to completely cut the workpiece during cutting, thereby ensuring the cutting efficiency;

[0032] In this embodiment, preferably, a movable groove 20 is opened at the top of the body 1, and a conveyor belt 21 is movably arranged inside the movable groove 20 via a rotating shaft;

[0033] Through the above solution, the use of the conveyor belt 21 makes it possible to push the workpiece toward the cutting assembly 5 without manual labor, thereby ensuring the safety of the workers during the shearing process and improving the overall safety of the device;

[0034] When the shearing machine for hardware products of the present embodiment that can limit the position of workpieces is in use, the material is placed on the top of the machine body 1 and the material is driven to move toward the roller 8 through the conveyor belt 21. When the material reaches the bottom of the roller 8, the material will squeeze the roller 8 upward through the spring 9. At the same time, the roller 8 will flatten the material on the top of the machine body 1 due to the spring 9, so that the material will not be lost due to deviation during the cutting process due to lack of fixation during subsequent cutting. At the same time, the fixing method is simple and convenient, which makes the device structure simpler. At the same time, moving the material through the conveyor belt 21 eliminates the need for the staff to manually push the material under the cutting component 5, so that the staff can avoid danger during work, which improves the safety of the device. After passing through the cutting groove 19, it will rest against one end of the positioning block 15, and the material will continue to be moved so that the positioning block 15 can drive the moving block 12 to move. At the same time, the pointer 18 fixed on the top of the moving block 12 will move inside the observation groove 16. By observing the position of the pointer 18 inside the observation groove 16 and comparing it with the scale 17, the distance moved by the material can be judged, so as to accurately locate the position of the material and cut it, which improves the accuracy of cutting and facilitates the operation of the staff. At the same time, after the material is cut, since the middle of the moving block 12 is hollowed out, the cut material will fall directly and slide to one end of the body 1 through the inclined surface, thereby realizing the recovery of the material. At the same time, the pointer 18 inside the observation groove 16 is moved to realize the return of the moving block 12.
