Title: Manufacture of multistage bent and punched tube and punch used therefor
Inventor: TAKEMOTO SHIGERU
IPC: B21D28/28
Filed: 1989-04-17
Abstract: PURPOSE:To easily punch a hole of a large inner diameter on a thick-wall tube by pressing a 1st punch from the upper surface of a bent tube to punch a hole of an oval section and notching both sides of the hole of an oval section with a 2nd punch in the shape of a circular arc to punch a circular hole. CONSTITUTION:When a 1st punching stage is carried out to hold the lower half of the tube 2, to press a 1st punch from the upper surface of the tube and to punch a hole of an oval section, slugs change into long and slender chips and fall in the tube. Further, when a 2nd punching stage is performed, arched slugs fall in the tube. Since the slugs punched in each stage are small, they are surely separated from the circumference of the hole and do not remain on the circumference of the hole. Since the respective slugs are long and slender, they are not stopped up or caught in the tube when they are flushed. In this way, a hole of a large inner diameter can be punched on the comparatively thick-wall tube and the slugs are not stopped up.
