[0002] Sheet metal shearing is the process of shearing sheets according to design requirements to obtain sheets that meet size requirements. Currently, most sheets are sheared by workers using metal shears. However, when workers use metal shears to shear sheets, the sheared sections are easily uneven due to hand shaking, resulting in low shearing accuracy. Workers are also required to trim the sheared sections, which increases the labor intensity of workers. Utility Model Content

[0005] Preferably, a fixed frame is provided on the workbench, and the fixed frame is vertically located on one side of the cutting frame, and a driving cylinder is provided on the fixed frame, and the driving cylinder is obliquely located on the top of the side of the fixed frame, and the driving cylinder is connected to the other side of the cutter, and the cutter is swung up and down on the side of the cutting frame through the driving cylinder.

[0006] Preferably, the driving cylinder pipeline is connected to an air pump, and the air pump is located on one side outside the workbench, and the air pump is connected to the cutter drive through the driving cylinder.

[0007] Preferably, an air guide tube is provided between the air pump and the driving cylinder, and both ends of the air guide tube are respectively connected to the air pump and the driving cylinder, and the driving cylinder is connected to the air pump pipeline through the air guide tube, and a mechanical control valve is connected to the pipeline on the air guide tube, and the mechanical control valve is laterally located on the side of the workbench, and the mechanical control valve is respectively connected to the air pump and the driving cylinder through a conduit.

[0009] In summary, this application has the following beneficial effects:

[0010] When the plate is placed horizontally on the top of the loading platform, the other side of the cutter is driven to swing downward on the side of the cutter frame, so that the other side of the cutter approaches the loading platform and forms a lever principle. Under the action of the lever principle, the bottom of the cutter contacts and squeezes the top of the plate extending out of the loading platform. At this time, the cutter will continue to move toward the loading platform and continue to squeeze the plate. In the process of continuous movement of the cutter, since the cutter and the loading platform are closely fitted, the plate extending out of the loading platform will be gradually cut off by the cutter. The cutter frame, cutter and loading platform cooperate with each other to thereby The method of shearing with a piece of metal shear replaces the method of shearing the sheet metal by workers, which not only reduces the labor intensity of workers, but also the cross-section of the sheet metal sheared by the above method is neat, and there is no need to further trim the cross-section. It effectively solves the technical problem that most of the sheets currently rely on workers to shear the sheets by operating the metal shears, but when workers operate the metal shears to shear the sheets, the cut cross-section is easily uneven due to hand shaking, resulting in low shearing accuracy, and the workers are required to trim the cross-section of the sheared sheet metal, which increases the labor intensity of workers.

[0018] A shearing mechanism for a shearing machine, see Figures 1 to 2The top of the workbench 2 is provided with a knife frame 3, and the knife frame 3 is bent outwards, and a knife 4 is arranged horizontally between the knife frame 3 and the workbench 2. One side of the knife frame 3 is hinged to the side of the knife frame 3, and the knife 4 is tightly fitted with the workbench 2, and the other side of the knife frame 3 is driven to swing at the side of the knife frame 3, so that the bottom of the knife 4 contacts and squeezes the top of the plate 13 placed horizontally on the top of the workbench 2, and then shears the plate 13 placed horizontally on the top of the workbench 2. In this embodiment, when the plate 13 is placed horizontally on the top of the workbench 2, the other side of the knife 4 is driven to swing downward on the side of the knife frame 3, so that the other side of the knife 4 approaches the direction of the workbench 2 and forms a lever principle. Under the action of the lever principle, the bottom of the knife 4 contacts the top of the plate 13 extending out of the workbench 2 The cutter 4 will continue to move toward the loading platform 2 and squeeze the plate 13. During the continuous movement of the cutter 4, the plate 13 extending out of the loading platform 2 will be gradually cut off by the cutter 4 due to the close fit between the cutter 4 and the loading platform 2. The method of shearing the plate 13 by the cooperation of the cutting frame 3, the cutter 4 and the loading platform 2 replaces the workers' operation of shearing the plate with the tin shears, which not only reduces the labor intensity of the workers, but also the cross-section of the plate cut by the above method is neat, and there is no need to further trim the cross-section. It effectively solves the problem that most of the current plates rely on workers to operate the tin shears to cut the plates, but when workers operate the tin shears to cut the plates, it is easy for the cut cross-section to be uneven due to hand shaking, resulting in low cutting accuracy, and the workers are also required to trim the cross-section of the cut plate, which increases the labor intensity of the workers.

[0019] The cutting frame 3 is detachably connected to a limiting pressure block 5, and the limiting pressure block 5 is vertically located at the side of the cutting frame 3. The limiting pressure block 5 is located parallel to the top of the loading platform 2, and the bottom of the limiting pressure block 5 contacts and limits the top of the plate 13 placed horizontally on the top of the loading platform 2. In this embodiment, by providing the limiting pressure block 5, the position of the plate 13 placed horizontally on the top of the loading platform 2 can be limited to prevent the plate 13 from shifting in position during the cutting process, thereby affecting the cutting accuracy of the plate 13. The limiting pressure block 5 and the cutting frame 3 are arranged to be detachable to facilitate replacement when the limiting pressure block 5 is damaged.

[0021] The driving cylinder 7 pipeline is connected to the air pump 8, and the air pump 8 is located on the side outside the workbench 1, and the air pump 8 is connected to the cutter 4 through the driving cylinder 7. In this embodiment, the external air is compressed by the air pump 8 to form compressed gas, and then the compressed gas is transported to the driving cylinder 7 and drives the driving cylinder 7 to drive the cutter 4 to swing on the side of the cutter frame 3.
