Abstract
PURPOSE: To decrease cut portions and to reduce the cost by machining the needle section of a punch and a head separately, then integrating them. CONSTITUTION: The lower face of a stripper 26 is brought into contact with a sheet and its downward motion is stopped, then only a cylinder holder 4 is lowered against a spring, and an extended head 9a is brought into contact with a punch 27 located below. The punch 27 is depressed against the spring 29 by the downward motion of the cylinder holder 4, and a sheet material is pushed by the depressed punch 27. The punch 27 stored in the shipper 26 is constituted of a head 27a and a needle section 27b. The head 27a and the needle section 27b are separately formed, and the head 27a and the needle section 27b are integrated by pressing in, bonding, or screwing. When the punch 27 is molded, cut portions are decreased, and its cost can be reduced.
