Abstract

PURPOSE: To change drawing length in a short time and lower the die cost by providing a mechanism of determining the position of the work according to the length of drawing by providing a plurality of locating pins in a manner as to project successively from the top surface of a drawing die.
CONSTITUTION: Locating pins 2a, 2b, 2c are freely slidably loose-inserted into the through-holes 7 of a drawing die 1, and the bottom ends thereof are abutted on the cams 4a, 4b, 4c secured to a revolving shaft 3. Lifting projections 5 are provided respectively with deviation by each fixed angle to the cams 4a, 4b, 4c, by the former of which the pins 2a, 2b, 2c are projected from the surface of the die 1 according to need. The revolving shaft 3 is rotated by a position control motor 10 to project the locating pins 2a, 2b, 2c according to the length l of drawing from the surface of the die 1, the work 13 is introduced, its position is determined, a punch 11 is lowered and both sides of the end part of the work 13 are drawn to a required length l. Thereby, the length l of the drawing is suitably changed.
