[0002] Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling steel strip after processing. Generally, the steel strip is unpacked, flattened, curled, and welded to form a round tube, which is then rolled into a square tube and then cut into the required length. Some square tubes have a large number of holes on the surface, so a punching die is needed to punch the square tube.
[0003] The punching die uses a punch to punch holes on the surface of the square tube. By manually flipping the square tube, holes can be punched on different sides of the square tube. The diameters of the square tubes are different, and the punching die cannot clamp and fix square tubes of different diameters in time. The bottom of the punching seat can only be supported by the support. The bottom of the punching die is not strong enough, which leads to errors in punching the square tube. Therefore, it is particularly important to design a punching die for square tube processing. Utility Model Content

Embodiment 2:
[0023] Based on the first embodiment, Figure 1 and Figure 4As shown, multiple torsion rods 6 are respectively rotatably connected to the outer wall of the first punching seat 1, the tops of the multiple suction cups 13 are each provided with a limit strip 12, the top of the covering plate 11 is fixedly connected to the bottom ends of the multiple vertical plates 10, a plurality of square tubes 15 are placed on the top of the first punching seat 1, and a plurality of clamping blocks 14 are fixedly installed on the top of the first punching seat 1. The utility model provides a punching die for square tube processing, which is provided with a through groove 9, a vertical plate 10, a torsion rod 6 and a clamping block 14. When the screw rod 5 rotates, the outer surface of the limit block 7 is tightly fitted with the inner wall of the first punching seat 1, thereby driving the limit block 7 threadedly sleeved therewith to move left and right inside the through groove 9.
[0024] Working principle: Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made of strip steel after process processing and rolling. Some square tube fittings 15 have a large number of holes on the surface, so it is necessary to use a punching die to punch the square tube fittings 15. The punching die itself is equipped with a punch 4. The punch 4 and the surface of the square tube fitting 15 are die-casted with each other to achieve the punching effect. The square tube fitting 15 is artificially placed in the middle position between the clamping block 14 and the limit block 7. The material of the clamping block 14 and the sponge pad 8 clamped by the square tube fitting 15 is sponge, which has a certain flexibility, reducing the squeezing force on the square tube fitting 15, and the square tube fitting 15 is still firmly limited at the top of the first punching seat 1, and the torsion rod is turned clockwise in sequence 6, driving the screw rod 5 to rotate, so that the limit block 7 gradually moves to the position close to the clamping block 14, so that the square pipe fittings 15 of different diameters can be clamped by the movement of the limit block 7, and the square pipe fittings 15 can be punched on different surfaces by flipping the square pipe fittings 15, thereby increasing the use range of the punching device. When the screw rod 5 rotates, the outer surface of the limit block 7 is tightly fitted with the inner wall of the first punching seat 1, thereby driving the limit block 7 threadedly mounted therewith to move left and right inside the through groove 9. The suction cup 13 and the covering plate 11 are fixed by the limit strip 12. The suction cup 13 can adsorb ceramic and steel materials. The bottom surface of the suction cup 13 can be adsorbed with the mounting surface, thereby enhancing the firmness of the bottom of the first punching seat 1 and improving the quality of punching.
