A kind of manufacturing process of cold-rolled channel steel

Abstract

The invention relates to a cold-rolled channel steel manufacturing process, which includes a bottom plate, side plates, two sliding grinding devices, a lifting grinding device and two collection frames. The top of the bottom plate is uniformly welded with side plates, and a There is a sliding grinding device, the sliding grinding device is installed on the base plate, the lifting grinding device is installed on the sliding grinding device, and the collecting frame is installed on the base plate. The cold-rolled channel steel manufacturing process provided by the present invention can solve the problem of manually grinding the internal space of the channel steel due to the small space inside the channel steel, the manual decontamination process is cumbersome, and the existing When processing cold-rolled channel steel manufacturing equipment, the cold-rolled channel steel is usually fixed first, and then its inner and outer surfaces are polished, and the grinding equipment is easy to bend the middle part of the channel steel, so that the middle part of the channel steel and the two The material removed by end grinding is inconsistent, which makes the channel steel need to be processed twice.

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 cross section, and channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures. Channel steel is often used in conjunction with I-beams. The edges and corners on both sides of the steel are prone to burrs, and after the channel steel is cold-rolled, it is usually necessary to cut the channel steel with channel steel shears or saw blades, so that the channel steel is easy to transport, and after the shear blade is aged or sawed After the sheet is damaged, it is very easy to tear the sheared part of the channel steel and have more burrs, so it is necessary to degrind the surface of the cold-rolled channel steel. [0003] The existing cold-rolled channe...

Problems solved by technology

[0004] (1) When the cold-rolled channel steel is ground by manual grinding, due to the small space inside the channel steel, it is difficult to manually grind the internal space of 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 manufactures and processes the cold-rolled channel steel, 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.
