Grinding machine for punching die

Abstract

The grinding machine comprises a machine box, a grinding mechanism for obliquely grinding the punching die is arranged in the machine box, the grinding mechanism comprises a transverse plate connected to the inner wall of the machine box in a sliding mode, and two vertical plates are fixedly connected to the lower end of the transverse plate; the side walls of the two vertical plates are jointly and rotationally connected with an annular frame through first rotating shafts, the inner walls of the two sides, away from the first rotating shafts, of the annular frame are rotationally connected with servo motors through second rotating shafts, the movable ends of the servo motors are fixedly connected with grinding discs, and the side walls, away from the movable ends, of the servo motors are fixedly connected with fixing columns. By arranging the grinding mechanism, the grinding disc can rotate in the inclined state, then the grinding disc can comprehensively grind the notch of the punching groove in the die, grinding is uniform, the subsequent punching quality is improved, and the situation that when the die is comprehensively ground, the die can only be rotated and then ground again, and the efficiency is low is avoided.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a grinding machine used for punching molds. Background technique [0002] After the punching die is used for a period of time, the punching edge of the die is gradually rounded and needs to be polished with a sander. [0003] In the patent "a bracket punching die lower die grinding machine" with the application number "201811317297.9", the solution drives the mounting seat to swing through the sector gear, so that the grinding disc can be tilted by rotating the motor, which can reduce the grinding of the grinding disc and the lower die. At the same time, manually rotating the chuck drives the lower mold to rotate, which is convenient for the grinding disc to tilt the lower mold for comprehensive grinding. However, this solution still has the following defects: [0004] 1. After the motor is tilted, only the contact surface of the mold and the grinding disc can be groun...

AI Technical Summary

Problems solved by technology

[0004] 1. After the motor is tilted, only the contact surface between the mold and the grinding disc can be polished. When the mold is completely polished, the mold can only be rotated and then polished again. quality;

[0005] 2. When the grinding disc grinds
