[0001] The utility model relates to the technical field of mechanical processing, in particular to a punching mechanism for rectangular tube processing. Background Art

[0002] A rectangular tube is a hollow long strip of steel, also known as a flat tube, a flat square tube or a square flat tube. In the construction industry, it is often necessary to punch holes in rectangular tubes for assembly.

[0003] The inventor discovered during the process of implementing the utility model:

[0004] The existing rectangular tube punching method mostly uses a punching punch to punch holes. The punching punch often causes deformation to the periphery of the rectangular tube when punching holes, making the diameter of the rectangular tube openings non-uniform, resulting in poor assembly effect of the rectangular tube. In addition, when adjusting the punching position of the rectangular tube, it is necessary to manually adjust the position of the rectangular tube continuously, which is time-consuming and labor-intensive, and is prone to errors, affecting the punching effect.

[0009] Preferably, two telescopic rods are fixed to the inner wall of the mobile frame, and a clamp is fixed to the extended end of each telescopic rod. A spring is sleeved on the outer surface of each telescopic rod. After the rectangular tube is placed between the two clamps, the two clamps can automatically clamp the rectangular tube through the elastic force of the spring, thereby ensuring the stability of the rectangular tube when moving and avoiding the phenomenon that the moving position of the rectangular tube is offset due to inertia when the rectangular tube is pushed to move.

By sliding the rectangular tube body 5 on the inner supporting block 203, the inner supporting block 203 can support the inside of the rectangular tube body 5. By pushing the supporting bottom plate 205 up by the hydraulic push rod 204, the bottom of the rectangular tube body 5 can be supported.

[0030] like Figure 1 and Figure 2 As shown, the upper surface of the lifting plate 403 is fixed to the extended ends of the two hydraulic push rods 402, and a punching perforator 404 is installed on the lower surface of the lifting plate 403. The punching perforator 404 is located directly above the inner support block 203, and the bottom end of the punching perforator 404 can be inserted into the through hole 206 of the inner support block 203 when descending.

[0031] The working principle of this utility model:

[0032] When in use, an appropriate inner support block 203 is installed on the support rod 202 according to the size of the rectangular tube body 5 and the punching requirements, and then the rectangular tube body 5 is sleeved on the inner support block 203, and the inner support block 203 is located directly below the punching punch 404, and a through hole 206 adapted to the punching punch 404 is opened on the inner support block 203, and then the support bottom plate 205 is pushed up by the hydraulic push rod 1 204, so that the support bottom plate 205 can support the bottom surface of the rectangular tube body 5, ensuring the stability of the rectangular tube body 5 and the inner support block 203, so that when the hydraulic push rod 2 402 drives the punching punch 404 to descend to punch the rectangular tube body 5, the inner support block 203 can support the inside of the rectangular tube body 5, avoiding the problem of local depression of the rectangular tube body 5 during punching;

[0033] When it is necessary to adjust the perforation position of the rectangular tube body 5, the servo motor 301 drives the threaded rod 302 to rotate to move the movable frame 303, so that the outer surface of the push plate 304 is attached to one end of the rectangular tube body 5, and the two clamping plates 306 clamp the two side surfaces of the rectangular tube body 5 under the action of the spring 307, so that the push plate 304 can push the rectangular tube body 5 to move, and then according to the distance the rectangular tube body 5 needs to move, the servo motor 301 is turned on to make the movable frame 303 move, so that the push plate 304 can smoothly push the rectangular tube body 5 to slide along the outer surface of the inner support block 203 for a corresponding distance, thereby achieving the effect that the device can automatically move the rectangular tube position, and each time the push plate 304 adjusts the position of the rectangular tube body 5, the hydraulic push rod 204 will drive the support bottom plate 205 to drop slightly to avoid friction between the rectangular tube body 5 and the support bottom plate 205. After the position adjustment is completed, the hydraulic push rod 204 will push the support bottom plate 205 back to its original position.
