Automatic grinding device for die punch arc

Abstract

The invention discloses an automatic grinding device for a die punch arc. The automatic grinding device comprises a screw lifting pair, a radius adjusting disc, a swing rod, a drive motor, a drive rod a, a drive rod b, a grinding head motor installing plate, an installing plate freedom degree limiting mechanism, a grinding head motor and a bowl-shaped grinding wheel. The drive motor drives the swing rod to drive the radius adjusting disc to swing, and therefore the installing plate and the grinding head motor on the installing plate are driven to do same-radius arc track swinging. The device is low in cost, reasonable in structure, convenient to use, practical and suitable for grinding the punch die blanking force reduction arc.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to an automatic arc grinding device for die punches. Background technique [0002] Grinding the center position of the composite die punch with the punch in a circular or linear arrangement into one or several arcs to disperse the punching force is a widely used method to reduce the punching force and punching noise of the die. Methods. [0003] The punch of the mold must be ground after each use. Usually, the blade is ground on an ordinary grinding machine. The wear size is large and the frequency is high. Since the mold is made of high-strength materials, the material is expensive , The processing technology is complicated, and frequent grinding will cause a huge waste of materials. Now some people grind the middle part of the die punch into a concave arc shape, but manual grinding is used, and the arc is purely manually processed, and the grinding amount, shape, size, co...
