Problems solved by technology
[0006] In order to solve the above problems, the present invention provides a punching die of C-shaped steel for steel structure, which can solve the problem that when punching elliptical connection holes of existing C-shaped steel, different types of C-shaped steel need to punch out elliptical holes with different widths. Different molds need to be replaced for punching, which is troublesome to replace. During replacement, due to the high surface temperature of the mold after work, personnel need to use tools to hold and remove it. It may fall off during clamping and hit personnel, causing personnel injuries and other difficult problems

The invention relates to a punching mould for C-shaped steel for a steel structure. The punching mould comprises a mounting frame, a width regulating mould and an insertion device, wherein the lower end of the mounting frame is equipped with the width regulating mould; and the insertion device is mounted at the upper side of the right end of the width regulating mould. The punching mould can solvethe problems such as personnel injury as C-shaped steel of different models needs to punch out oval holes of different width, personnel needs to replace different moulds to punch, replacement is troublesome, the personnel needs to clamp and hold by virtue of a tool if the surface temperature of the worked mould is relatively high during replacement, and the mould possibly drops and smashes the personnel during clamping when oval connecting holes are punched in existing C-shaped steel, can realize an automatic regulating function on the mould, does not require the personnel to replace the mould, can be automatically regulated to be a corresponding stamping mould according to the working needs, improves working efficiency, and prevents the personnel from being injured as a result of improper operation during mould replacement.
Description
technical field [0001] The invention relates to the field of C-shaped steel punching, in particular to a punching die for C-shaped steel used in steel structures. Background technique [0002] C-shaped steel is automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the forming process of the C-shaped steel according to the given size of the C-shaped steel. The C-shaped steel is processed by hot coil and cold-bending. Compared with the same strength, the material can be saved by %, and punching treatment is required in the processing of C-shaped steel, and the elliptical connection hole targeted by the present invention. [0003] However, the existing C-shaped steel has the following defects when punching elliptical connection holes: 1. Because different types of C-shaped steel need to punch out elliptical holes with different widths, personnel need to change different molds to punch holes, which ...
