One side of the reinforcing arc plate 6 close to the processing table 3 is fixedly installed with an inclined rod 7. The inclined rod 7 is connected to the reinforcing arc plate 6 through an assembly plate 8. One end of the inclined rod 7 away from the reinforcing arc plate 6 is fixedly connected with a cross rod 9. The end of the cross rod 9 away from the inclined rod 7 extends into the horizontal plate 5 and is fixedly connected with the horizontal plate 5. The surface of the processing table 3 is provided with an arc surface adapted to the processing of tubular sheet metal parts. The vertical plate 4 and the horizontal plate 5 are perpendicular to each other and do not contact each other. The reinforcing arc plate 6 is adapted to the processing arc surface in the processing table 3. The inclined rod 7 and the cross rod 9 cooperate with the reinforcing arc plate 6 to form a triangular structure to provide support for the reinforcing arc plate 6.

[0030] One side of the reinforcing arc plate 6 close to the inclined rod 7 is fixedly installed with an assembly plate 8. One side of the assembly plate 8 close to the horizontal plate 5 is fixedly installed with a limiting plate 10. One end of the inclined rod 7 passing through the limiting plate 10 is fixedly connected with the reinforcing arc plate 6. Reinforcing rods 11 are fixedly installed at both ends of the limiting plate 10. The limiting plate 10 is fixedly installed on one side of the horizontal plate 5 close to the assembly plate 8 through the reinforcing rods 11. The assembly plate 8 is adapted to the reinforcing arc plate 6, and can cooperate with the triangular structure formed by the inclined rod 7 and the cross rod 9 to provide support for the reinforcing arc plate 6, improving the compressive capacity of the reinforcing arc plate 6. The limiting plate 10 is connected to the horizontal plate 5 through the reinforcing rods 11, thereby cooperating with the assembly plate 8 to improve the compressive capacity of the horizontal plate 5.

[0031] One side of the vertical plate 4 away from the processing table 3 is fixedly installed with a reinforcing block 12. The vertical plate 4 is fixedly installed with a positioning plate 13 through the reinforcing block 12. The bottom of the positioning plate 13 is fixedly connected to the top of the fixture frame 2.

[0035] During use, the motor in the processing table 3 drives the rotating shaft 15 to rotate, so that the metal buckle 17 connected to the rotating shaft 15 through the eccentric shaft 16 deflects, and extrudes the tubular sheet metal part in the through hole 14 of the positioning plate 13 fixed to the fixture frame 2 through the reinforcing block 12 and the vertical plate 4, making one end of the sheet metal part always fit with the reinforcing arc plate 6, thus ensuring the stability during the sheet metal processing. At the same time, the electric push rod in the lifting groove 18 takes the tubular sheet metal parts waiting for processing, and uniformly places the waste tubular sheet metal parts in the waste groove 19, so as to distinguish them from the normal sheet metal parts and reduce the interference with the sheet metal processing. During this process, the main body structure of the device is composed of the processing table 3 with a processing arc surface in cooperation with the vertical plate 4 and the cross plate 5. The reinforcing arc plate 6 adapted to the processing table 3 and its structure strengthen the overall anti-bending function of the processing table 3. The inclined rods 7 and the cross rods 9 cooperate with the reinforcing arc plate 6 to form a triangular structure to provide support for the reinforcing arc plate 6. At the same time, through the assembly plate 8 adapted to the reinforcing arc plate 6, the triangular structure formed by the inclined rods 7 and the cross rods 9 provides support for the reinforcing arc plate 6, improving the compressive resistance of the reinforcing arc plate 6 and the limiting plate 10 connected to the cross plate 5 through the reinforcing rod 11, so as to cooperate with the assembly plate 8 to improve the compressive resistance of the cross plate 5, so that the device is not easily deformed under pressure when facing tubular sheet metal parts with greater strength, ensuring the stable progress of the bending work of the tubular sheet metal parts.
