Abstract

PURPOSE: To improve forming accuracy of precision parts by providing a wear prevented guide post to a header for plastic working of machine parts.
CONSTITUTION: A dies block 6 is fixed to the body of a header, and a punch block 7 repeats sliding vertically and longitudinally in the direction shown by the arrow. In this while, a work 8 is worked by a punch 3 or 4 and a die 5. During preliminary forming by the punch 3 and die 5, guide pins 1-a, 1-b are guided by guide bushes 2-b, 2-c. During finish forming by the punch 4 and die 5 pins 1-a, 1-b are guided by 2-a, 2-b respectively. These pins and bushes are surface hardened by nitriding treatment etc., and the bush is provided with an oil groove 9.
