Abstract
PURPOSE: To work cylindrical members with good accuracy without buckling even in the use of a long punch by guiding the punch by means of a stripper and collet at all times.
CONSTITUTION: During descending of a slide 2, a stopper 6 stops near the top surface of a die 1 and during working, it prevents buckling of a punch 4. Since the bore of a collet 16 is worked with minus tolerance with respect to the diameter of punch land, the collet 16 advances together with the punch 4 up to the tapered part without stopping on the way in a die hole 12. In the tapered part, the collet 16 stops, but the punch 4 still advances and starts working. During working, the collet 16 guides the punch 4 while being pushed up by the work 18. The collet 16 guides the part near the leading end of the punch 4 as far as possible.
