[0029] The cutting assembly 4 is fixedly mounted on the bottom of the fixing assembly 6, and the cutting assembly 4 is rotatably connected to the transmission member 8;

[0030] The conveying assembly 5 is fixedly mounted on the top of the base 1, and the conveying assembly 5 passes through the gantry 2 and is vertically arranged;

[0031] Among them, the cutting assembly 4 includes a rotating shaft 41, which is rotatably connected to the fixing assembly 6, and the rotating shaft 41 is rotatably connected to the transmission member 8. A cutter disc 42 is rotatably connected to the middle of the outer side of the rotating shaft 41, and a circular plate 43 is fixedly connected to the outer side of the rotating shaft 41.

The long strip chips and granular chips generated when cutting metal will be guided and discharged by the through grooves 412 and the guide grooves 413 at different positions respectively. The large holes can allow larger chips to pass smoothly, and the small holes can handle smaller chips. This ensures that the chips can be continuously and smoothly discharged from the cutter disc 4. 2.

By setting the through groove 412 and the material guide groove 413, stress can be guided to be transmitted along different paths to avoid excessive stress concentration, and the stress distribution at the edge of the cutter disc can be made more uniform. There are multiple slide grooves 411, and the multiple slide grooves 411 are evenly distributed around the rotating shaft 41. A through groove 412 is provided on the outside of the cutter disc 42. The through groove 412 and the material guide groove 413 are of different sizes.

The hydraulic cylinder 3 is connected to an external power supply to work, and the hydraulic cylinder 3 drives the slider 61 to move downward, and the slider 61 drives the extension plate 63 to move downward, so that the bent plate 65 contacts the top of the connecting plate 59. As the hydraulic cylinder 3 continues to move downward, the pressure roller 58 contacts the top of the metal sheet, thereby fixing the two sides of the cutting position of the metal sheet to prevent the metal sheet from moving, causing the cutting line to deviate from the predetermined position, thereby affecting the cutting accuracy. Due to the interaction between the cutter disc 42 and the metal sheet during the cutting process, the metal sheet may vibrate, which will not only interfere with the cutting operation, but also make the cutting surface rough. When the two sides of the cutting position are fixed, the vibration amplitude of the metal sheet can be reduced. There are two spring plates 56, and the two spring plates 56 are square plates 51.

During the movement, the metal sheet is located in the middle of the conveying assembly 5 under the elastic force of the spring plates 56 on both sides. The hydraulic cylinder 3 is connected to an external power supply and the hydraulic cylinder 3 drives the slider 61 to move downward. The slider 61 drives the extension plate 63 to move downward, so that the bent plate 65 contacts the top of the connecting plate 59. As the hydraulic cylinder 3 continues to move downward, the pressure roller 58 contacts the top of the metal sheet, thereby fixing the two sides of the cutting point of the metal sheet.

[0036] The motor 7 is connected to an external power supply to work, and the motor 7 drives the rotating shaft 41 to rotate through the transmission member 8, and the rotating shaft 41 drives the circular plate 43 to rotate. Under the action of centrifugal force, the ring block 48 slides inside the slide groove 411 in the direction away from the rotating shaft 41, so that the cylinder 47 on the ring block 48 is located inside the through hole 45. Through the clamping connection between the through hole 45 and the cylinder 47, the rotating shaft 41 drives the cutter disc 42 to rotate through the circular plate 43. When the cutter disc 42 is stuck during cutting, extrusion is generated between the cylinder 47 and the through hole 45, and the cylinder 47 drives the ring block 48 to move inside the slide groove 411, so that the cylinder 47 is away from the through hole 45, so that the circular plate 43 rotates inside the annular groove 44 through the fixing ring 46. At the same time, the end of the ring block 48 away from the cylinder 47 contacts the rotating shaft 41, and the rotating shaft 41 stops rotating under the action of the friction between the ring block 48 and the rotating shaft 41.
