2) after sliding for a certain distance, the first sliding plane 212 of the driving block 210 and the second sliding plane 224 of the sliding block 220 start to contact and continue to slide, and when the sliding end point is reached, the two planes have larger contact areas to bear the acting force of the insert 600 on the sliding block 220 during stamping, and at this time, the sliding block 220 and the insert 600 thereon are at the highest point (see fig. 7) to participate in the stamping process;

3) conversely, the piston rod (320) of the cylinder is contracted, the driving block 210 is pulled back, the first sliding plane 212 is separated from the second sliding plane 224, and the slide block 220 slides downwards along the first sliding inclined plane 211 of the driving block 210 due to the force of the return spring 400 until the lower plane thereof contacts the base plate 120, at which time the slide block 220 and the insert 600 thereon are lowered to the lowest position (see fig. 8), and do not participate in the punching process.

Taking the fender mold mentioned in the background art as an example, in order to switch whether the insert 600 (specifically, an insert) participates in the flanging, the conventional method is to disassemble the mold and then install the mold, which takes about 2 hours, during which the stamping line also needs to be stopped.

If the switching device provided by the embodiment is used, after a certain type of stamping task is finished, only the air path switch is controlled, and the type changing can be finished. The production line of present is intelligent for a long time, and the gas circuit switch can be taken into account in the intelligent control of the production line, so that the influence on the rhythm of the production line is little, and the time spent in the process is negligible.
