Description

Steel sheet fillet cutting device

Technical Field

The invention relates to the technical field of steel plate processing, in particular to a steel plate fillet cutting device.

Background

Steel plates are the main raw material of motorcycle accessories, and in order to increase the service life of the steel plates, anticorrosive paint is generally coated on the steel plates. Because there is stress concentration's physical characteristic at steel sheet edge edges and corners, and the anticorrosive paint adhesion force of edge edges and corners is poor, easily makes the steel sheet take place the corrosion phenomenon to all around from the edge to influence the life of steel sheet. Therefore, in the process of processing the steel sheet, it is necessary to perform a round treatment for the edge corner.

Among the many methods of treating the rounded corners, the most common method is grinding with a grinding wheel. At present, the grinding wheel grinding method is manually operated, and has the following defects: 1. the steel plate needs to be manually fixed by hands during polishing, the fixation is unstable, the steel plate is easy to move in the polishing process, the polishing precision is influenced, the technical requirements of round corners are difficult to meet, and new small-edge corners are often generated after sharp corners are polished; 2. the steel plate needs to be manually measured before being polished to determine the circle center of the fillet, so that the consistency of the fillet angle is ensured, the operation process is complex, the labor efficiency is low, the processing precision is low, and the labor loss is large; 3. the working environment of workers is severe due to high decibel noise and dust splashing generated during the operation of the grinding wheel, and if the dust removal function is added, the cost is too high and is not practical; 4. the grinding wheel is used for grinding the cutting allowance into metal powder, so that recycling is not facilitated, and resource waste is large.
