Manufacturing and machining process of cold-rolled channel steel

Abstract

The invention relates to a manufacturing and machining process of cold-rolled channel steel. The manufacturing and machining process comprises a bottom plate, side plates, two sliding grinding devices, lifting grinding devices and two collecting frames, the side plates are evenly welded to the upper end of the bottom plate, the sliding grinding devices are arranged between the side plates, the sliding grinding devices are installed on the bottom plate, the lifting grinding devices are installed on the sliding grinding devices, and the collecting frames are installed on the bottom plate. According to the manufacturing and machining process of the cold-rolled channel steel, the problems that the space inside the channel steel is small during manual grinding, thus it is difficult to grind thespace inside the channel steel manually, the manual decontamination process is tedious, when an existing cold-rolling channel steel manufacturing device machines, the channel steel is usually fixed first after cold-rolling, then the inner and outer surfaces of the channel steel are grinded, the middle of the channel steel is prone to being bended by a grinding device, thus materials removed by grinding the middle and the two ends of the channel steel are inconsistent, so that the channel steel needs to machined again can be solved.

Description

Technical field [0001] The invention relates to the technical field of steel manufacturing and processing, in particular to a cold-rolled channel steel manufacturing and processing technology. Background technique [0002] Channel steel is a long strip of steel with a groove-shaped section. Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures. Channel steel is often used in conjunction with I-beam. Channel steel is cold-rolled and formed. Burrs are prone to appear at the edges and corners of the steel. After the channel steel is cold-rolled and formed, the channel steel is usually cut by a channel steel cutter or a saw blade, so that the channel steel is convenient for transportation. After the sheet is damaged, it is very easy to have the phenomenon of tearing of the sheared part of the channel steel and more burrs, so it is necessary to de-grind the surface of the channel steel after cold rolling. [0003] The existing cold-r...

Problems solved by technology

[0004] (1) When grinding the cold-rolled channel steel by manual grinding, because the inner space of the channel steel is small, it is difficult to manually grind the space inside the channel steel, so that the surface treatment of the channel steel is not thorough, and the channel steel Stains on the outside of the steel need to be manually removed, and the stain removal process is cumbersome, resulting in low production efficiency of channel steel;

[0005] (2) When the existing cold-rolled channel steel manufacturing equipment is manufacturing and processing the cold-rolled channel steel, because the existing grinding equipment usually fixes the cold-rolled channel steel first, and then grinds the inner and outer surfaces sequentially , The processing time is long. During the processing, the grinding equipment is easy to bend the middle part of the longer channel steel, so that the materials removed by grinding the middle part of the channel steel and the two ends are inconsistent, resulting in the need for secondary processing of the channel steel.
