RAPIER TAPE PUNCHING MACHINING DIE FACILITATING HIGH-SPEED PRODUCTION

摘要

A rapier tape punching machining die facilitating high-speed production, comprising an upper die assembly and a lower die assembly. The upper die assembly comprises an upper die plate (2), a punch retaining plate (3), punches (4), and a stripper plate (5); a die shank (1) is connected onto the upper die plate (2); the punch retaining plate (3) is mounted on the lower surface of the upper die plate (2); the upper surface of the stripper plate (5) is connected to the lower end of a stripper spring (11); the upper end of the stripper spring (11) is fixed into the punch retaining plate (3); the punches (4) pass through the stripper plate (5) and the punch retaining plate (3) and the top of the punches is connected to the lower surface of the upper die plate (2); the lower die assembly comprises a female die (7) and a lower die plate (9); the female die (7) is mounted on the upper surface of the lower die plate (9); the female die (7) and the lower die plate (9) are fixed by means of a locating pin (8); channels allowing heads of the punches (4) to pass through are arranged on the female die (7); a guide pin (6) passes through the stripper plate (5) and the punch retaining plate (3); the top of the guide pin (6) is connected to the lower surface of the upper die plate (2); the lower end of the guide pin (6) is inserted into the female die (7). The rapier tape punching machining die can avoid the occurrence of phenomena of fiber punching shear failure and fiber tear during a rapier tape punching process, and facilitates high-speed production.
