接触が行なわれる欠点を有していた。Prior Art Conventionally, in order to punch out the above-mentioned soft material, cardboard,
A punched board made of semi-rigid synthetic material such as vinyl chloride or acrylic is placed on a non-buffering board made of a strong hard material such as iron or concrete, and the board is placed on this board. A method of punching into an arbitrary shape by placing a soft material on the top surface of a punching board and pressing down the soft material so that the lowest point of the punching die digs into the wall thickness of the punching board by about 0.2 mm+. According to this conventional method, the blade of the punching die is recessed in the punching plate, and the position where the blade is formed must be constantly moved to avoid contact with the soft material during the next punching. However, it is labor-intensive and the punching plate must be replaced every certain number of punches, which is expensive and uneconomical, and the cutting edge of the punching die is severely worn out. In order to eliminate such defects, there is also Japanese Patent Application Laid-Open No. 58-180321 proposed by the present applicant, but although this method significantly improves the above-mentioned defects, the cutting edge of the punching die still comes into contact with the punching plate. Although it is extremely rare, it has the disadvantage that in addition to contact with soft materials, contact occurs that causes wear and tear on the cutting edge.

This invention prevents cutting and wear of the cutting edge, and eliminates the various drawbacks mentioned above that have occurred in the past.Means for solving the problemsThe present invention solves the problems mentioned above by using a vertically movable tool. A soft material for punching and forming is placed on the upper surface of the receiving member, and a cutting blade is placed on the lower surface of this soft material, and the lowermost position of the member, which is located on the upper surface of the cutting blade, is
A method for punching a soft material, in which a space of note is formed between the cutting blade and the cutting blade, and the cutting blade cuts into the soft material without penetrating it, and reaches a position where an uncut part is formed in the soft material. The equipment used to embody this method includes a vertically movable receiving member whose upper surface is provided with a mounting surface for a soft material to be punched and formed, and a receiving member that can be placed on the mounting surface of this receiving member. A cutting blade is positioned facing the part to be cut into the soft material, and the cutting blade is located on the upper surface of the cutting blade through the soft material, and forms a gap between the cutting blade and the cutting blade when it is lowered to its lowest point. and a member in which the cutting blade cuts into the soft material without penetrating it to form an uncut portion in the soft material.

ことができるものである。Function As described above, in this invention, a soft material for punching and forming is placed on the upper surface of a vertically movable receiving member, and a cutting blade is placed on the lower surface of this soft material, and the cutting blade is cut through the soft material. The lowest position of this member located on the upper surface forms a certain distance between the cutting blade and the cutting blade cuts into the soft material without penetrating it, forming a non-cutting part in the soft material. Since the cutting blade and this member do not come into contact with each other, the cutting force will not be worn out or damaged, and there will be no need to move or replace the member. In addition, the soft part that is punched out with the uncut part left must be thin or can be easily peeled off by a station hand or blown away with air.
