Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically a shearing machine for preventing scratches on sheet metal. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It utilizes a moving upper blade and a fixed lower blade, with a suitable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. Shearing machines belong to the forging and pressing machinery category and are primarily used in the metal processing industry. These machines are widely used in aerospace, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical appliances, decoration, and other industries, providing specialized machinery and complete sets of equipment. After shearing, the shearing machine should ensure the straightness and parallelism of the sheared surface of the sheet metal and minimize sheet metal distortion to obtain high-quality workpieces.

[0003] Most existing sheet metal shearing machines place the sheet metal on the workbench surface for shearing. The sheet metal inevitably rubs against the workbench surface. If there are particles and debris on the workbench surface, the surface of the sheet metal can be easily scratched, requiring repair of the sheet metal surface after shearing, which increases the workload and causes inconvenience to the user. Utility Model Content

[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a shearing machine for preventing scratches on sheet metal during sheet processing. When shearing sheet metal, the moving sheet metal body, together with the transfer assembly, ensures the moving accuracy of the sheet metal through the cooperation of the sliding plate and the mounting box, as well as the cooperation of the sliding sleeve and the crossbar, thus preventing the sheet metal from shifting. Once the sheet metal is under the shearing blade, the hydraulic cylinder is activated, and the output end of the hydraulic cylinder drives the shearing blade downward to shear the sheet metal. During the shearing process, the sheet metal will not rub against other objects, thereby avoiding scratches on the sheet metal surface.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A shearing machine for processing sheet metal to prevent scratches includes a mounting frame with support legs fixedly connected to its bottom. Multiple transfer components are mounted on the mounting frame, and a machine frame is fixedly mounted on the mounting frame. A hydraulic cylinder is mounted on the machine frame, and a shearing blade is fixedly connected to the output end of the hydraulic cylinder. Each transfer component includes a mounting box, and a sliding plate is fixedly connected to the inner side of the mounting frame. The sliding plate passes through the mounting box, and the mounting box and the sliding plate are rotatably connected. Rotating shafts are symmetrically installed inside the mounting box, and pressure rods are fixedly connected to the rotating shafts. When shearing the sheet metal, the sheet metal body, along with the transfer components, is moved. Through the cooperation of the sliding plate and the mounting box, as well as the cooperation of the sliding sleeve and the crossbar, the movement accuracy of the sheet metal is ensured, preventing deviation. Once the sheet metal is under the shearing blade, the hydraulic cylinder is activated. The output end of the hydraulic cylinder drives the shearing blade downwards to shear the sheet metal. During the shearing process, the sheet metal does not rub against other objects, thus preventing scratches on the sheet metal surface.

[0007] More preferably, the transfer assembly further includes a pressure plate, a connecting post is fixedly connected to the pressure rod, a limit slider is fixedly connected to one side of the connecting post, a limit frame is fixedly connected to the pressure rod, and the inner wall of the limit frame is in contact with the outer side of the limit slider.

[0008] More preferably, a gear is fixedly connected to the rotating shaft, and two gears within the same mounting box mesh with each other. This meshing of the two gears within the same mounting box ensures the synchronous movement of the pressure rod.

[0009] More preferably, an electric push rod is movably mounted on the mounting box, and the output end of the electric push rod is rotatably connected to the pressure rod above it. The up and down movement of the pressure rod is controlled by the extension and retraction of the electric push rod.

[0010] More preferably, limiting rings are symmetrically fixedly connected to the limiting slider, and the limiting frame is located between the two limiting rings. The two limiting rings are used to limit the lateral distance between the pressure rod and the pressure plate, ensuring the stability and movement accuracy of the pressure rod.

[0011] More preferably, a crossbar is fixedly connected to the bottom of the mounting bracket, a sliding sleeve is fitted onto the crossbar, and a vertical rod is fixedly connected to the sliding sleeve. The top end of the vertical rod passes through two pressure plates in sequence. This sequential passing of the top end of the vertical rod through the two pressure plates ensures the stability and movement accuracy of the pressure plates.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, through the design of the transfer component, allows the moving plate body, together with the transfer component, to ensure the moving accuracy of the plate and prevent plate deviation when shearing the plate. This is achieved through the cooperation of the sliding plate and the mounting box, as well as the cooperation of the sliding sleeve and the crossbar. Once the plate is under the shearing blade, the hydraulic cylinder is activated, and the output end of the hydraulic cylinder drives the shearing blade downward to shear the plate. During the shearing process, the plate will not rub against other objects, reducing the direct contact between the plate and the workbench surface, avoiding scratches on the plate surface caused by friction, and improving the surface quality of the plate.

[0014] 2. The gears, limiting frames, and limiting sliders in the transfer assembly of this utility model ensure the synchronous movement of the pressure rod, thereby improving the shearing accuracy and stability. Attached Figure Description

[0024] like Figure 1-4 As shown, a shearing machine for scratch-resistant sheet metal processing includes a mounting frame 1. A support leg 2 is fixedly connected to the bottom of the mounting frame 1. Multiple transfer components are mounted on the mounting frame 1. A frame 19 is fixedly mounted on the mounting frame 1. A hydraulic cylinder 3 is mounted on the frame 19. A shearing blade 4 is fixedly connected to the output end of the hydraulic cylinder 3. The transfer components include a mounting box 5. A sliding plate 6 is fixedly connected to the inner side of the mounting frame 1. The sliding plate 6 passes through the mounting box 5, and the mounting box 5 and the sliding plate 6 are rotatably connected. Rotating shafts 7 are symmetrically mounted inside the mounting box 5, and pressure rods 8 are fixedly connected to the rotating shafts 7. When shearing the sheet metal, the moving sheet metal body, together with the transfer assembly, is moved with the cooperation of the sliding plate 6 and the mounting box 5, as well as the cooperation of the sliding sleeve 17 and the crossbar 16. This ensures the moving accuracy of the sheet metal and prevents it from shifting. Once the sheet metal is under the shearing blade 4, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 drives the shearing blade 4 to move downwards to shear the sheet metal. During the shearing process, the sheet metal will not rub against other objects, thus avoiding scratches on the sheet metal surface.

[0025] In another embodiment, the transfer assembly further includes a pressure plate 9, a connecting post 10 is fixedly connected to the pressure rod 8, a limiting slider 11 is fixedly connected to one side of the connecting post 10, a limiting frame 12 is fixedly connected to the pressure rod 8, and the inner wall of the limiting frame 12 is in contact with the outer side of the limiting slider 11.

[0026] In another embodiment, a gear 13 is fixedly connected to the rotating shaft 7, and two gears 13 within the same mounting box 5 mesh with each other. This meshing of the two gears 13 within the same mounting box 5 ensures the synchronous movement of the pressure rod 8.

[0027] In another embodiment, an electric push rod 14 is movably mounted on the mounting box 5. The output end of the electric push rod 14 is rotatably connected to the pressure rod 8 above, and the up and down movement of the pressure rod 8 is controlled by the extension and retraction of the electric push rod 14.

[0028] In another embodiment, limiting rings 15 are symmetrically fixedly connected to the limiting slider 11, and the limiting frame 12 is located between the two limiting rings 15. The two limiting rings 15 are used to limit the lateral distance between the pressure rod 8 and the pressure plate 9, ensuring the stability and movement accuracy of the pressure rod 8.

[0029] In another embodiment, a crossbar 16 is fixedly connected to the bottom of the mounting bracket 1, a sliding sleeve 17 is fitted onto the crossbar 16, and a vertical rod 18 is fixedly connected to the sliding sleeve 17. The top end of the vertical rod 18 passes through two pressure plates 9 in sequence. The top end of the vertical rod 18 passes through the two pressure plates 9 in sequence to ensure the stability and movement accuracy of the pressure plates 9.

[0030] Working principle:

[0031] Using this device, the sheet material to be cut is placed between the two pressure plates 9 in the transfer assembly. Then, the electric push rod 14 is activated to extend and drive the upper pressure rod 8 to rotate around the rotating shaft 7. Since the two gears 13 in the same mounting box 5 mesh with each other, the two pressure rods 8 move towards each other, thereby pressing the sheet material firmly and fixing it in the mounting frame 1 with the pressure plate 9 on the pressure rod 8. Multiple transfer assemblies clamp the sheet material at the same time, so that the sheet material is in a horizontal state.

[0032] When shearing the sheet metal, the moving sheet metal body, together with the transfer assembly, can ensure the moving accuracy of the sheet metal through the cooperation of the sliding plate 6 and the mounting box 5, as well as the cooperation of the sliding sleeve 17 and the crossbar 16, and avoid the sheet metal from shifting. When the sheet metal is under the shearing blade 4, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 drives the shearing blade 4 to move downward to shear the sheet metal. During the shearing process, the sheet metal will not rub against other objects, thus avoiding scratches on the surface of the sheet metal.
