It has the characteristics of high efficiency, precision, and stability, can greatly improve production efficiency and product quality, and reduce labor costs. It is an important tool in modern manufacturing.

[0003] When using a numerically controlled cutting machine, the sheet material is first fixed on its workbench. The bracket fixed with the processing mechanism is driven by a motor to move, and at the same time, the processing mechanism can also move on the bracket, so that the processing mechanism can freely move on the surface of the sheet material according to the operation requirements, thereby realizing various processing of the sheet material.

[0004] When the numerically controlled cutting machine performs processing such as cutting, punching, and grooving on the sheet material, waste chips will be generated on the surface of the sheet material. If the generated waste chips are not cleaned, they will float in the air or inside the machine. The waste chips floating in the air will affect the physical health of workers, and the waste chips falling into the machine will affect the normal operation of the machine and are difficult to clean.

The number of the racks 12 is two, and the two racks 12 are symmetrically distributed. The two racks 12 enable the two gears 11 on the surface of the support shaft 10 to rotate simultaneously, so that both ends of the support shaft 10 are stressed, avoiding the deformation of the support shaft 10 caused by one end driving the other end to rotate. The rack 12 and the gear 11 are meshed. A dust collection frame 14 is fixedly arranged at the bottom of the operating table 1. A dust exhaust component is arranged at the bottom of the dust collection frame 14. A driven rod 17 is rotatably arranged inside the support 8. Blades 21 are fixedly arranged on the surface of the driven rod 17. For this numerically controlled sheet metal cutting machine for easy cleaning, when the screw rod 3 rotates, the threaded block 7 moves on its surface, thereby enabling the support 8 to move. The movement of the support 8 enables the moving block 9 to move. The movement of the moving block 9 drives the support shaft 10, the gear 11 and the cleaning rods 13 to move. When the gear 11 moves, the gear 11 rotates through the rack 12. The rotation of the gear 11 drives the support shaft 10 to rotate. The rotation of the support shaft 10 drives the cleaning rods 13 to rotate. The cleaning rods 13 rotate and move at the same time to sweep the waste chips staying on the operating table 1 into the dust collection frame 14 through the through grooves 25, and then the waste chips are extracted and centrally processed through the dust exhaust component. This device can clean the waste chips generated during the processing of the sheet material, avoiding the dispersion of the waste chips from affecting the physical health of the workers and the operation of the machine, and improving the convenience of cleaning the waste chips.

Start the dust conveying fan 15 to extract the waste chips inside the dust collection rack 14 and discharge them through the dust conveying pipe 16. When the cutting mechanism operates on the sheet, the screw rod 3 makes the driving rod 19 rotate through the third belt pulley 23, the fourth belt pulley 22 and the second synchronous belt 24 at the same time. The rotation of the driving rod 19 drives the worm 20 to rotate. The rotation of the worm 20 drives the worm gear 18 to rotate. The rotation of the worm gear 18 drives the driven rod 17 and the blade 21 to rotate.
