排出するのである。Embodiments of the present invention will be described in detail below with reference to the drawings. The board material a is like an asbestos-cement board material, and is formed into a semi-cured state, and is formed into a roof tile made of an asbestos-cement board. The blade 2 is attached to a lifting die 4 for press-molding the outer shell shape of the flat roof tile A,
The edge portion 1 is formed by edging a punched shape, and the blade 2 itself is formed in a hollow cylindrical shape. The inner surface of the blade 2 has a tapered hole 3 that widens upward. Then, the plate material a placed and transferred on the carrier plate 5 via the felt 6, the urethane rubber 7 and the like is lowered by the elevating die 4 so that the edge portion 1 of the blade 2 is inserted into the plate material a. Punch out. In such a case, the punched object b has entered the blade 2, and when the lifting table 4 is raised, the punched object b is attached to the inner surface of the edge portion 1 and does not come out. Next, after the carrier plate 5 is advanced by a certain pitch, the lifting table 4 is moved.
To lower and punch out.
The object b to be punched out in the blade 2 in the previous step is pushed up along the upwardly wide tapered hole 3 formed on the inner peripheral surface of the blade 2 by the object b'to be punched in the blade 2 in the subsequent step. Of. The pushed up punched object b'is extruded by high-pressure air, water, etc., discharged by a suction means such as a vacuum pump, and discharged by mechanical force.

It pushes up along the upwardly wide tapered hole 3 formed in the surface, and the pushed up punched object b'is discharged to the outside, and the plate material a fed up and down by moving the blade 2 up and down. A hollow cylindrical blade 2
The punched objects b, b '... Entering inside can be discharged to the outside from the upper one, and the structure is simplified for the hole processing on the green sheet. Since such punching is performed simultaneously with the punching of the outer shell shape of the roof tile, it is possible to perform the punching at a precise position without using a positioning mechanism.

正確に行うことができるという利点がある。[Effects of the Invention] In summary, according to the present invention, the punched object punched into the blade in the previous step by the hollow tubular tool is formed on the inner peripheral surface of the blade by the punched object punched in the post step. Since it is a method of pushing up along the upwardly wide tapered hole and discharging the pushed up punched object to the outside,
The plate material fed up and down and punched into a predetermined shape can be punched out into a predetermined shape, and the punched material that enters the hollow cylindrical blade can be discharged from the upper one to the outside. The method has an advantage that its structure can be simplified and that a hole having a complicated shape can be easily and accurately performed.
