[0002] Steel is a strip steel with a certain cross-sectional shape and size, and is one of the four major types of steel. Steel mainly includes C-shaped steel, I-shaped steel, channel steel, angle steel, H-shaped steel, rail steel, U-shaped steel, steel sheet piles, etc. According to the cross-sectional shape, steel is divided into simple cross-sectional steel and complex cross-sectional steel. Steel is widely used in various fields, such as industrial construction, metal structures, bridges, ships, agricultural machinery and vehicle manufacturing, transmission towers, transportation machinery, etc.

[0003] Among them, C-shaped steel is a profile formed by cold bending or hot rolling strip steel through a cold bending forming machine. It is named because its cross-sectional shape resembles the English letter "C". C-shaped steel has the characteristics of thin wall, light weight, and good cross-sectional performance. Compared with traditional channel steel, it can save about 30% of materials at the same strength. It is widely used in purlins and wall beams of steel structure buildings, and can also be used in columns, beams and arms in mechanical light industry manufacturing. C-shaped steel has various specifications to meet different engineering needs.

[0004] Most of the punching devices used in traditional C-shaped steel production can only fix and clamp C-shaped steel of one specification, and cannot be adjusted according to the different thicknesses, widths and lengths of the C-shaped steel, so the flexibility of use is low; and most of the devices can only punch holes on one side of the C-shaped steel after fixing the C-shaped steel. After punching the holes, the steel must be turned over and fixed, and then punched again. It is impossible to punch holes on three sides of the C-shaped steel at the same time, resulting in low punching efficiency. Utility Model Content
