[0002] Traditional cutting methods often face the problem of insufficient precision. For some metal structural parts with strict requirements for dimensional accuracy, this will lead to an increase in the defective rate. Moreover, early cutting devices were inefficient, with slow cutting speeds, which seriously affected production capacity during large-scale production.

[0003] The patent with the application number 202320872416.7 relates to a metal sheet cutting device, which includes a support base. A C-shaped bracket is fixed on the outside of the support base, and a driving motor is fixedly connected to the top of the C-shaped bracket. The output shaft of the driving motor penetrates the C-shaped bracket and is fixedly connected to a spline shaft a. This patent is different from the prior art. By starting the electric push rod a, the telescopic inner column is pushed to move upward, and then the lower clamping plate moves upward. With the cooperation of the upper clamping plate, metal steel plates to be processed with different thicknesses can be clamped and fixed, with a wide range of applications. Secondly, using a downward synchronous cutting component, by starting the driving motor and the electric push rod b, and with the cooperation, the cutting knife rotates and can move vertically downward while driving the clamped metal steel plate to be processed to rotate, and then high-efficiency cutting into circular steel plates is achieved. There is no need for manual holding of cutting equipment for cutting, greatly improving the cutting efficiency. However, when cutting metal parts, this device is prone to cutting deviation, difficult to ensure cutting accuracy, and prone to accidentally injuring workers. Therefore, a cutting device for metal structure manufacturing is proposed to solve the above-mentioned problems. Summary of the Invention

The movement of the lifting rod 6 drives the cutter device 3 to move for position adjustment, enabling the device to adapt to metal parts of different sizes. Before cutting, the cylinder 13 can be started by the main console to work. The cylinder 13 drives the clamping plate 14 to move through the output end to clamp the metal parts, avoiding cutting deviation, thus ensuring the cutting dimension accuracy, reducing the time for the operator to adjust the position of the metal parts, improving the work efficiency. While clamping the metal parts, the movement of the clamping plate 14 drives the connecting rod 16 to move. The movement of the connecting rod 16 drives the first pulley 20 to move.

The downward movement of the first pulley 20 drives the sliding rod 15 to move downward. The movement of the sliding rod 15 drives the fixed plate 17 to move. The movement of the fixed plate 17 drives the elastic telescopic rod 18 to move. The elastic telescopic rod 18 drives the pressing plate 19 to move through the telescopic end, thereby realizing the elastic pressing of the metal parts, preventing the metal parts from displacing or shaking during the cutting process, ensuring the smooth progress of the cutting process, making the cut shape more complete, improving the cutting accuracy, and making the quality of the metal parts better.

[0019] While clamping the metal parts, the movement of the clamping plate 14 drives the pull rod 81 to move through the hinge point. The movement of the pull rod 81 drives the protective shell 82 to move through the hinge point, thereby driving the left and right protective shells 82 to approach each other. The protective shell 82 can absorb part of the impact force, reduce the damage to the cutting equipment, thus extending the service life of the equipment, reducing the equipment maintenance cost, and improving the cutting efficiency. After cutting, the movement of the mobile platform 12 to the reset position drives the positioning block 83 to move.

While cleaning the workbench 1, the reciprocating movement of the scraping plate 86 drives the positioning plate 91 to move. The movement of the positioning plate 91 drives the first convex block 92 to move. The movement of the first convex block 92 drives the knocking rod 94 to move by contacting the second convex block 95 through the circumferential surface to knock the workbench 1.

[0021] Working principle: While cleaning the workbench 1, the scraping plate 86 reciprocates to drive the positioning plate 91 to move. The movement of the positioning plate 91 drives the first bump 92 to move. The movement of the first bump 92 drives the knocking rod 94 to move through the contact of the circumferential surface with the second bump 95 to knock on the workbench 1. When the first bump 92 leaves, the knocking rod 94 is reset by the spring, thereby realizing the reciprocating knocking on the workbench 1, avoiding the influence of subsequent cleaning work and cutting operation due to debris accumulation near the recovery hole, saving the cleaning time of the staff, making the working life of the equipment longer, reducing the occurrence of deep cleaning or maintenance due to serious blockage, improving the working efficiency. While cleaning the workbench 1, the moving table 12 moves to drive the convex plate 96 to move. The movement of the convex plate 96 drives the arc plate 99 to move through the contact surface. The movement of the arc plate 99 drives the conduction plate 98 to move to dredge the workbench 1. When the dredging is completed, it is reset by the spring, thereby realizing the reciprocating dredging, which helps the stable operation of the equipment, reduces the performance degradation caused by problems such as equipment overheating, and then improves the cutting efficiency and quality, reduces the production cost, and improves the service life of the equipment.
