[0011] 3. Beneficial effects

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] The utility model drives the upper mold fixing plate to move downward through an external transmission structure to drive the mold plate to achieve mold closing. The round tube receives pressure to become a flat tube of a certain size, and is subjected to the pressure of the punching machine. The tube mouth is cut by the arc cutting block, and the punching column punches a hole of a certain size in the flat tube. Therefore, the punching machine can complete the three actions of flattening, arc cutting and punching in one movement, which greatly improves work efficiency, reduces the inaccuracy caused by using multiple molds, and saves production costs.

The upper mold plate 3 is connected by a rubber spring 13; the bottom of the upper mold fixing plate 3 is fixedly connected with a guide sleeve 301 near the corner, and the upper end of the lower mold concave plate 4 is fixedly connected with a guide column 401 plugged into the guide sleeve 301 near the corner; the upper end of the outer positioning plate 6 is fixedly connected with an outer positioning U-shaped seat 601 for placing the circular tube 14, and the outer side of the outer positioning U-shaped seat 601 is plugged with an outer positioning pin 602 for fixing the circular tube 14; the upper end surface of the lower mold plate 2 is fitted with a rubber pad 7, and the upper end of the pad 7 is penetrated by a pad positioning hole 701, and the pad positioning hole 701 on the outer side of the pad 7 is plugged with a bolt to fix the pad 7 to the upper end of the lower mold plate 2; the rubber spring 13 is in an elastic state by default.

[0023] Based on the above structure, when the device is used, the staff connects the mold handle 5 to the power end of the driving structure, so that the upper mold plate 1 can be pushed down to close the mold during the upper and lower mold closing process. The round tube 14 is placed in the outer positioning U-shaped seat 601 at the upper end of the outer positioning plate 6 in advance, and fixed with the matching outer positioning pin 602. During the mold closing process, the guide sleeve 301 on the outside of the upper mold fixing plate 3 slides along the guide column 401 on the upper end of the lower mold concave plate 4, so that the upper and lower mold plates are accurately molded and docked. As the upper mold fixing plate 3 moves downward, the rubber spring 13 is compressed by pressure. At this time, the upper mold plate 1 pre-extrudes the circular tube 14 and docks it at both ends of the mold groove 8 to squeeze it flat, and the arc cutting block 11 and the punching column 12 at the bottom of the upper mold fixing plate 3 will also penetrate the arc cutting block hole 9 and the punching column hole 10 at the bottom of the upper mold plate 1, and then dock with the circular tube 14. The pipe mouth of the circular tube 14 is therefore cut by the arc cutting block 11, and the punching column 12 punches a hole of a certain size from the flat end of the circular tube 14, thereby completing the three actions of flattening, arc cutting and punching at one time, which is very convenient to use.
