Before the die is closed to punch the part with hole, the driving guide slide mechanism on the upper die base drives the wedge driving seat to move to the upper end of the oblique slide block. When the die starts to be closed, the material pressing stroke of the material pressing device in the upper die base enables the material pressing device to press the molded surface of the lower die in advance. The upper die base continues to move downwards, an inclined sliding block which is arranged in the material pressing device and has a certain angle moves downwards in an inclined mode under the driving of the pushing force of the inclined wedge driving seat of the upper die base, and meanwhile the inclined material pressing plate can be driven to move along the punching direction of the special-shaped punching male die to press the lower die molded surface. And then, the upper die base continues to move downwards, the distance between the oblique sliding block and the oblique material pressing plate is compressed and reduced, and the oblique sliding block obliquely downwards presses the special-shaped punching male die to punch into the profile (cutting edge) of the lower die so as to complete punching. When the stamping of the die is finished and the upper die base begins to move upwards, the wedge driving base moves upwards along with the upper die base, the oblique sliding block and the punch die comprising the special-shaped punching hole move upwards, the compression distance between the oblique sliding block and the oblique pressure plate is released, and the oblique sliding block is separated from the contact with the profile (cutting edge) of the lower die after being separated from the profile (cutting edge) of the lower die. And the special-shaped punching male die and the inclined material pressing plate enter the material pressing device, the upper die base moves upwards to drive the material pressing device releasing the material pressing stroke to move upwards, and the one-round punching process is finished.

Before the die is closed to punch a non-porous part, the driving guide sliding mechanism on the upper die base drives the wedge driving base to leave the upper end face of the oblique sliding block and the contact range of the oblique sliding block. When the die starts to close the die and punch the non-porous part, the material pressing stroke of the material pressing device in the upper die base starts, so that the material pressing device can press the molded surface of the lower die in advance. The upper die base continues to move downwards, the inclined sliding block which is arranged in the material pressing device and is in a certain angle does not move due to the fact that the inclined sliding block is not driven by the inclined wedge driving seat, and therefore the special-shaped punching male die cannot expose the material pressing device in the die punching process, and cannot affect an un-punched stamping part.

In the mechanism, the driving slide guide mechanism fixed in the upper die holder drives the inclined wedge driving seat to be in inclined contact with or separated from the inclined slide block without contact, so that the pneumatic quick change effect is achieved, and the die can be quickly switched between hole flanging mode and hole flanging mode according to the requirement of actual conditions. The mechanism transformation mould is arranged on the existing automobile mould, so that the existing mould has hole flanging and hole non-flanging modes. Therefore, new secondary processing equipment does not need to be installed, and the increase of production cost, factory floor space, energy consumption and the like is further avoided.

2. Through set up the slant sliding block that can reciprocating motion in the eccentric swage. When the hole is not turned, the oblique sliding block can push the oblique sliding block to integrally drive the special-shaped punching male die and the oblique pressing plate to be far away from the material pressing device by utilizing the release of the stroke of the reset nitrogen cylinder arranged on the material pressing device. When hole flanging is performed, the inclined wedge driving seat arranged on the upper die seat can be utilized to drive the inclined sliding block in an inclined mode, the nitrogen cylinder is moved downwards to compress and reset, the lower die profile is pressed by the inclined pressure plate, meanwhile, the special-shaped punching male die is enabled to protrude into the lower die profile, and the purpose of inclined punching is achieved.

Therefore, the mechanism transformation mould is arranged on the existing automobile mould, so that the existing mould has two modes of hole flanging and hole non-flanging. Therefore, new secondary processing equipment does not need to be installed, and the increase of production cost, factory floor space, energy consumption and the like is further avoided.

3. Through the guide pillar, the guide sleeve, the material pressing nitrogen cylinder and the anti-disengaging screw which are arranged between the oblique sliding block and the oblique material pressing plate, the oblique material pressing plate can move along the punching direction of the special-shaped punching male die to press the lower die surface, and the stability of the material pressing effect is guaranteed.
