It includes a main body, a worktable at the upper end of the main body, rollers on the inner wall of the worktable, limiting mechanisms on both sides of the worktable, a pressing mechanism at the upper end of the worktable, and a mounting frame on one side of the worktable. This utility model, through the combined action of a servo motor, rotating rod, sliding plate, fixed rod, fixed groove plate, and limiting rod, enables the punching and shearing mechanism of this steel mesh punching and shearing machine to limit the movement of the steel mesh. Through the combined action of a connecting frame, threaded rod, handwheel, moving plate, and pressure roller, it enables the punching and shearing mechanism to press the steel mesh. Through the combined action of a fixed seat, mounting groove, guide rod, spring, insert block, extrusion cone, fixing bolt, and cutter, it enables the punching and shearing mechanism to disassemble the cutter.

[0004] However, in actual use, when the steel mesh is punched and sheared, the wires break and the cut is impacted, which easily produces metal fragments. The metal fragments are small and easily splash, making them difficult to clean. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a punching and shearing mechanism for a steel mesh punching and shearing machine, which provides protection during the punching and shearing process, improves the safety of the processing environment, and facilitates the collection of debris.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punching and shearing mechanism for a steel plate mesh punching and shearing machine, including a punching and shearing frame, a pressure plate slidably connected to the inner wall of the punching and shearing frame, a negative pressure pipe fixedly connected to the top of the pressure plate, a suction pipe fixedly connected inside the pressure plate, a collection box fixedly connected to one side of the punching and shearing frame, a suction pipe fixedly connected to one end of the collection box, a corrugated telescopic bend fixedly connected to one end of the suction pipe, a filter screen inserted into the inner wall of the collection box, and a collection mesh box fixedly connected to one side of the filter screen.

[0007] By adopting the above technical solution, when the steel mesh is punched and sheared, the pressure plate can be pressed down and fixed close to the cut. At the same time, the suction pipe draws suction from the side above the cut, and negative pressure is generated inside the negative pressure pipe, which diverts the flow to the suction pipe. Under the action of suction, the debris is prevented from splashing. The debris is sucked into the suction pipe and then enters the negative pressure pipe. The corrugated telescopic bend can extend and retract with the rise and fall of the pressure plate, and has strong flexibility and can present various shapes. The debris enters the collection box and is filtered by the filter screen. The debris falls into the collection mesh box for collection. The filter screen can be disassembled and cleaned.

[0015] By adopting the above technical solution, the pressure plate descends, causing the anti-slip strip to come into contact with the steel mesh, thereby fixing the steel mesh.

[0016] A further feature of this invention is that the inner wall of the punching and shearing frame is provided with a sliding groove, and both ends of the pressure plate are fixedly connected with sliders.

[0017] By adopting the above technical solution, the slider moves along the inner wall of the groove when the pressure plate is raised and lowered.

[0018] A further feature of this invention is that a punch shear is provided on the top of the pressure plate, and a hydraulic telescopic rod is provided on the top of the punch shear.

[0019] By adopting the above technical solution, the punch shears are raised and lowered by a hydraulic telescopic rod.

[0020] A further feature of this invention is that the number of straws is several, and the several straws are distributed at equal intervals.

[0021] By adopting the above technical solution, the straws are evenly distributed, resulting in a larger suction distribution range.

[0022] A further feature of this invention is that the straw extends into the interior of the negative pressure tube, and the inner wall of the negative pressure tube is coated with a wear-resistant coating.

[0036] A punching and shearing mechanism for a steel mesh punching and shearing machine includes the following embodiments:

[0037] Example 1:

[0038] Reference Figure 1-4 A pressure plate 2 is slidably connected to the inner wall of the punching and shearing frame 1. A negative pressure pipe 3 is fixedly connected to the top of the pressure plate 2. A suction pipe 4 is fixedly connected to the inside of the pressure plate 2. A collection box 5 is fixedly connected to one side of the punching and shearing frame 1. A suction pipe 6 is fixedly connected to one end of the collection box 5. A corrugated telescopic bend pipe 7 is fixedly connected to one end of the suction pipe 6. A filter screen 8 is inserted into the inner wall of the collection box 5. A collection net box 9 is fixedly connected to one side of the filter screen 8.

[0039] Specifically, when the steel mesh is punched and sheared, the pressure plate 2 can be pressed down and fixed near the cut. At the same time, the suction pipe 4 sucks on the side above the cut, and negative pressure is generated inside the negative pressure pipe 3, which is diverted to the suction pipe 4. Under the action of suction, the debris is prevented from splashing. The debris is sucked into the suction pipe 4 and then enters the negative pressure pipe 3. The corrugated telescopic bend 7 can extend and retract with the rise and fall of the pressure plate 2, and has strong flexibility and can present various shapes. The debris enters the collection box 5 and is filtered by the filter screen 8. The debris falls into the collection box 9 for collection. The filter screen 8 can be disassembled and cleaned. It is protected during the punching and shearing process, improves the safety of the processing environment, and facilitates the collection of debris.

[0040] Example 2:

[0041] Reference Figure 1-4 A fan 10 is fixedly connected to the inner wall of the collection box 5. A disassembly cover 11 is snapped onto one side of the collection box 5. A punching and shearing table 12 is fixedly connected to the bottom of the punching and shearing frame 1. A frame plate 13 is fixedly connected to the inner wall of the punching and shearing frame 1. A cylinder 14 is fixedly connected to the top of the frame plate 13. A telescopic rod 15 is fixedly connected to the output end of the cylinder 14. The bottom of the telescopic rod 15 is fixedly connected to the pressure plate 2. An anti-slip strip 16 is fixedly connected to the bottom of the pressure plate 2. A sliding groove 17 is opened on the inner wall of the punching and shearing frame 1. A slider 18 is fixedly connected to both ends of the pressure plate 2. A punching and shearing 19 is set on the top of the pressure plate 2. A hydraulic telescopic rod 20 is set on the top of the punching and shearing 19. There are several suction tubes 4. The suction tubes 4 are distributed in an equidistant manner. The suction tubes 4 extend into the interior of the negative pressure pipe 3. The inner wall of the negative pressure pipe 3 is coated with a wear-resistant coating. A receiving platform 21 is fixedly connected to one end of the punching and shearing table 12. The height of the punching and shearing table 12 is greater than that of the receiving platform 21.

[0042] Specifically, after the blower 10 starts, it performs suction. The cover 11 can be removed. The punching and shearing table 12 is fixed to the punching and shearing frame 1. There are two frame plates 13. When fixing the steel mesh, the cylinder 14 starts, driving the telescopic rod 15 to extend. The pressure plate 2 descends, causing the anti-slip strip 16 to contact the steel mesh and fix it. When the pressure plate 2 rises and falls, it causes the slider 18 to slide on the inner wall of the slide groove 17. The punching and shearing 19 is controlled to rise and fall by the hydraulic telescopic rod 20. The suction pipe 4 is evenly distributed, so the suction force distribution range is large. The inside of the negative pressure pipe 3 is protected by wear-resistant material to prevent it from being worn by debris.

Simultaneously, the suction pipe 4 draws suction from the side above the cut, creating negative pressure inside the negative pressure pipe 3, which diverts the flow to the suction pipe 4. Under the suction force, debris is prevented from splashing. The debris is sucked into the suction pipe 4 and then into the negative pressure pipe 3. The corrugated telescopic bend 7 can extend and retract with the rise and fall of the pressure plate 2, exhibiting high flexibility and capable of various shapes. The debris enters the collection box 5 and is filtered by the filter screen 8. The debris falls into the collection mesh box 9 for collection. The filter screen 8 can... The material is disassembled and cleaned, and protected during the punching and shearing process to improve the safety of the processing environment and facilitate the collection of debris. After the blower 10 is started, it performs suction. The cover 11 can be removed. When fixing the steel mesh, the cylinder 14 is started, which drives the telescopic rod 15 to extend. The pressure plate 2 descends and drives the anti-slip strip 16 to contact the steel mesh to fix it. The suction pipe 4 is evenly distributed, so the suction force distribution range is large. The inside of the negative pressure pipe 3 is protected by wear-resistant material to prevent it from being worn by debris. The receiving platform 21 and the punching and shearing platform 12 have a height difference, which facilitates the descent of the punching and shearing blade 19 for cutting.
