[0003] For example, the Chinese patent with announcement number CN103203408B (an automatic side punching mold for a multi-station forming machine): includes a punch rod, a die and a positioning slider, a reserved part installation groove is provided on the upper end face of the positioning slider, the inner cavity of the die includes a cylindrical hole and a truncated cone-shaped expansion hole located at the upper end of the cylindrical hole and a cylindrical expansion hole located at the lower end of the cylindrical hole, the positioning slider is located in the inner cavity of the above-mentioned die, and the bottom outer edge protrusion of the positioning slider is connected with the transition step surface between the cylindrical hole and the cylindrical expansion hole, a punching slider is also provided above the positioning slider, and the punching sliders are distributed on the outer periphery of the reserved part installation groove, and the back of the punching slider is close to the inner surface of the truncated cone-shaped expansion hole, and a clamping block is also sleeved on the punch rod, which can push the punching slider to move downward along the inner surface of the truncated cone-shaped expansion hole when the punch rod presses down the positioning slider. The automatic side punching die of the multi-station forming machine obtained by the invention can cooperate with the multi-station forming machine to realize side punching of a stretched part on the multi-station forming machine.

[0004] However, the existing stretched parts formed by the multi-station forming machine are taken to the automatic punching machine for punching. The back and forth picking up and taking is low in production efficiency, time-consuming and labor-intensive, and is also prone to causing the punching position to shift and have low accuracy. Therefore, it does not meet the existing needs. In this regard, we propose an automatic side punching mold for a multi-station forming machine. Utility Model Content

[0009] Preferably, both ends of the force-bearing plate are provided with a rotation shaft, and the force-bearing plate is rotatably connected to the connecting frame via the rotation shaft.

[0010] Preferably, a mounting base plate is provided at the lower end of the double-headed cylinder, and the mounting base plate is threadedly fixed to the double-headed cylinder by fixing bolts provided on both sides.

[0011] Preferably, a lower base is welded to the lower end of the mounting base plate, and the lower base is made of stainless steel.

[0012] Preferably, the punching head is in a conical shape, and several of the punching heads and the punching plate are detachable.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] After the punching is completed, the connecting frames at both ends are driven to move toward the middle by the double-headed cylinder, thereby pulling the punching assembly to rotate, and then the object is taken out, thereby realizing automatic punching operation. Compared with the existing method of taking out the object and then punching the hole through the punching machine, there is no need to align the punching position twice, and there is no need to take the object time and effort, which saves time and effort and improves efficiency. The conventional stretched part formed by the multi-station forming machine is taken to the automatic punching machine for punching, and the back and forth taking is low in production efficiency, time-consuming and labor-intensive, and is also prone to cause the punching position deviation and low accuracy.
