A top pad facing the product panel and having an insertion hole formed at one side thereof, the top pad includes a bush disposed in the insertion groove to determine a scrap shape when the cam pierce works, and automatically scraps the scrap out during the cam pierce work. Take-out means arranged on the lower die for take-out;

       In addition, the take-out means includes a magnetic pierce punch fixedly arranged on one side of the cam slider.

       The magnetic piercing punch may further include: a magnetic pin disposed to protrude forward from the inside of the magnetic pierce punch; a spring provided inside the pierce punch to press the magnetic pin; and a rear of the spring to support the spring. It is composed of a spring support.

       In addition, the take-out means includes a gap detecting sensor spaced apart from each other on one side of the lower die and the cam slide.

       In addition, the take-out means is disposed on one side of the lower die, the gap detecting sensor provided on one side of the lower die and the electrical member connected to the magnetic pierce punch.

       In addition, the take-out means includes a return spring disposed at the upper end of the lower die and the end of the cam slide.

       In addition, the bushing is a case disposed on one side of the upper pad, a bushing groove in which one side of the case provided to enable the change of the scrap shape concave, and a support for supporting the product panel during cam piercing operation It consists of.

       In addition, the lower die is provided with a scrap receiving outside to load the scrap taken out by the take-out means.

The present invention is provided with a dispensing means in the lower die in order to automatically withdraw the scrap to the outside of the cam piercing device for the press die in the cam piercing operation, to facilitate the scrap processing by taking out the scrap to the outside rather than inside the product, There is an advantage that can smoothly solve the problem of lack of space when working with the top piercing punch.

In addition, minimizing the size of the bush has the effect of expanding the utilization of the mold space, there is an advantage that can change the scrap shape and size due to the minimization of the bush size.

       Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

        2 is a view showing a cam piercing scrap extraction apparatus according to the present invention, Figure 3 is a view showing a cam piercing apparatus according to another embodiment of the present invention, Figure 4 is a cam according to another embodiment of the present invention It is a figure which shows the state which scrape is taken out outside after a piercing operation.

       As shown in FIG. 2, an upper pierce punch 110 disposed on one side of the lower die 130 and a lower portion of the upper pierce punch 110 to pressurize the product panel 10. A lower die 120 disposed to face the cam, a cam driver 60 disposed on the other lower side of the upper die 130, and a cam driver 60 disposed to face the cam driver 60 to drive the cam driver 60. In a piercing device for a press die composed of a cam slide (70) interlocked to the upper die, disposed on the side of the upper die 130, the upper die pad facing the product panel 10, the insertion hole 22 is formed on one side 20 and the upper pad 20 are bushes 40 provided in the insertion hole 22 to determine the scrap shape during the cam piercing operation, and to automatically take out the scrap to the outside during the cam piercing operation. It includes a take-out means 50 provided on the lower die 120 The.

       The ejection means 50 includes a magnetic pierce punch 58 fixedly disposed at one side of the cam slider 70, and the magnetic pierce punch 58 is forward in the magnetic pierce punch 58. A magnetic pin 56 protruding from the spring, a spring 52 provided inside the magnetic pierce punch 58 to press the magnetic pin 56, and a spring 52 disposed behind the spring to It is composed of a spring support 54 for supporting. In addition, the take-out means 50 includes a gap detecting sensor 90 which is spaced apart from one side of the lower die 120 and the cam slide 60, respectively.

       The take-out means 50 is disposed on one side of the lower die die 120, the electrical member 100 connected to the gap detection sensor 90 and the magnetic pierce punch 58 provided on one side of the lower die die 120. ).

       The take-out means 50 includes a return spring 80 disposed at an upper end of the lower die 120 and an end of the cam slide 60.

       The bush 40 includes a case 42 disposed on one side of the upper pad, a bush groove 46 in which one side of the case 42 provided to enable the change of the scrap shape is concave, and a cam. It consists of a support 44 which supports the product panel 10 in the piercing operation.

       The lower die die 120 is provided with a scrap receiving device 30 to the outside to load the scrap is taken out to the outside by the take-out means (50).

Looking at the operation of the present invention configured as described above are as follows.

As shown in Figures 2 and 3, when the cam drive 60 is lowered according to the press lowering, and the cam slide 70 is interlocked with the cam drive 60 is advanced, one side of the lower die die 120 and the cam The gap detecting sensor 90 spaced apart from one side of the slide 70 is installed to operate the gap detecting sensor 90 when the gap is widened, and the gap detecting sensor 90 and the cam slider ( The magnetic pin 56 is magnetic by sending electricity into the magnetic pierce punch 58 by the electrical member 100 connected to the magnetic pierce punch 58 disposed at one side of the 70.

The spring is disposed inside the magnetic pierce punch 58 when the magnetic pin 56 is attached to the product panel 10 and pressed by the product panel 10 by the advancing cam slide 70. 52 is pressurized and the spring is supported by a spring support provided inside the magnetic pierce punch 58. At this time, the magnetic piercing punch 58 performs a piercing, the shape of the scrap is changed according to the shape of the bush 40 provided to determine the scrap shape when the magnetic pierce punch 58 and the cam pierce work.

As shown in FIG. 4, as the press rises, the cam drive 60 rises, and the cam slide 70 interlocks and moves backward. At this time, the spring 52 disposed inside the magnetic pierce punch 58 is expanded, and the magnetic magnetic pin 56 is attached to the scrap produced by the cam piercing operation to take out the product panel 10. . The gap detecting sensor 90 stops working according to the return of the magnetic pierce punch, and the magnetic pin 56 also loses magnetism.
