Like this, the third cylinder can drive the clamp plate that punches a hole and realize going up and down, can provide certain pressure simultaneously, prevents that the sheet metal from producing in cut-out press and rocking, and the precision that the guarantee punched a hole, the guide bar can prevent that the clamp plate that punches a hole from taking place the skew.

As an optimization, the station switching mechanism comprises a fourth cylinder arranged on the support, the fourth cylinder is horizontally arranged, a free end of the fourth cylinder is fixedly connected with the first cylinder, and the first cylinder is fixedly connected with the second cylinder through a connecting rod.

Like this, the flexible subassembly that punches a hole and the subassembly that punches a hole in advance that can drive of the action of fourth cylinder realize horizontal migration, under the effect of connecting rod, the subassembly that punches a hole and the subassembly synchronous motion that punches a hole in advance realize the switching of the subassembly that punches a hole and two stations of the subassembly that punch a hole in advance according to the position difference that the fourth cylinder stopped, and is efficient.

As optimization, the upper surface of cut-out press is provided with the constant head tank, the unloading hole runs through the setting and is in the constant head tank, still be provided with the recess in the constant head tank, set up the roof in the recess, the roof upper surface with the upper surface of constant head tank flushes, just right in the recess the roof is provided with the fifth cylinder.

Like this, after punching a hole the completion, the clamp plate that punches a hole lifts the back, and the production of fifth cylinder drives the sheet metal with the roof and rises, breaks away from the constant head tank, realizes quick unloading, raises the efficiency.
