Guide and mis-feeding protection dual-purpose mechanism for strip

Abstract

The invention discloses a guide and mis-feeding protection dual-purpose mechanism for a strip. The bottom surface of an upper die seat is connected with an upper liner plate; the bottom surface of theupper liner plate is connected with a male die fixing plate; the bottom surface of an unloading plate seat is connected with an unloading plate; the unloading plate clings to the strip; a flanged screw plug, a rectangular spring, a regulating rod and a mis-feeding pin regulating rod are arranged in sequence in a vertical through hole running through the upper die seat and the upper liner plate; the lower end of the mis-feeding pin regulating rod is connected with a mis-feeding pin; the mis-feeding pin runs through the male die fixing plate, the unloading plate seat and the unloading plate; the circular-arc-shaped head of a detecting rod is arranged in a circular-arc-shaped groove in the surface of the mis-feeding pin regulating rod; the detecting rod is connected with a mis-feeding microswitch; the head of the mis-feeding pin is prominent relative to the bottom surface of the unloading plate; the size of a gap between the mis-feeding pin and a guide hole of the strip is set to be equal to the size of a gap between a guide pin and the guide hole of the strip; the inner wall of a through hole, through which the mis-feeding pin passes, of the unloading plate seat and the unloading plate is connected with a locating sleeve; the inner wall of the locating sleeve is provided with an O-shaped sealing ring; and the locating sleeve is used for clamping the mis-feeding pin by the O-shaped sealing ring.

Description

technical field [0001] The invention relates to a strip guide and misfeed protection mechanism for a multi-station progressive die. Background technique [0002] The multi-station progressive die mold is composed of multiple stations, and the position accuracy between the multiple stations needs to be guaranteed by the guide pin positioning strip. During the high-speed punching process of the mold (≥300 times / min), how to avoid the damage of the mold edge due to the misfeeding of the strips due to the inappropriate delivery of the strips by the feeder, it is necessary to quickly and sensitively trigger the misfeeding micro switch to use the misfeeding pin. The machine tool stops to guarantee. The design position of the guide pin is generally on both sides of the strip. The gap between the guide pin and the guide hole in the strip is generally controlled within 0.02mm. The position of the detection hole for the misfeed pin is generally selected from one of the non-important ...
