Description
Technical Field
The utility model belongs to the field of steel plate measurement, and particularly relates to a flange inclination detection clamping plate of H-shaped steel.
Background
The H-shaped steel is an economic section high-efficiency section with more optimized section area distribution and more reasonable strength-to-weight ratio, and the section is named as the English letter H and consists of a web plate positioned in the middle and flanges positioned at two sides. Because each part of the H-shaped steel is arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving, light structure weight and the like in all directions, and the H-shaped steel is widely applied in all fields at present.
After the H-shaped steel is produced, in order not to influence the subsequent use, parameters such as performance, size and the like of the H-shaped steel are generally required to be detected, and unqualified products are removed. The width, length, thickness, inclination and the like of flanges on two sides of the H-shaped steel belong to one of detected parameters.
The clamping plate is a measuring device for measuring the inclination errors of flanges at two sides of the H-shaped steel in the prior art, however, the prior clamping plate, such as some clamping plates recommended in YB/T4423-2014 clamping plates for the inclination of the flanges of the H-shaped steel, is difficult to conveniently measure for H-shaped steel with thick specification and large specification. For example, in the steel industry, for H-section steel products specified by the requirements of GB/T11263-2017 Hot rolled H-section steel and part T-section steel, the width of the flange is generally 100mm to 500mm, and the measurement of the inclination of the flange with large width is quite inconvenient. Moreover, the rolling connection part of the web plate and the flange of the H-shaped steel is excessively formed by the circular arc fillets, and when the clamping plate measures the inclination of the flange, the clamping plate is required to be pressed and positioned so as to prevent the clamping plate from moving to cause measurement errors, so that the circular arc fillets at the rolling connection part of the web plate and the flange can influence the pressing and positioning of the clamping plate, the flange inclination of the H-shaped steel with all specifications cannot be accurately measured in the conventional clamping plate mode, various measuring tools with different specifications are required to measure, and the measuring tools are heavy and the measuring process is complicated.
The Chinese patent application number is: CN201420545389.3, publication date: patent literature on the 22 days of 2015 7 months discloses an H-shaped steel flange inclination measuring tool, and belongs to the technical field of section steel hot rolling devices. The device is formed by cutting a common steel plate by a wire, and consists of a web datum line, an inner datum line, an outer datum line and a handle. When the flange inclination of the H-shaped steel is detected in a large batch, the measuring tool is only required to be clamped on the leg part of the H-shaped steel, and then the feeler gauge is used for measuring the widest record of the leg datum line and the leg part of the H-shaped steel, namely the flange inclination value. The measuring tool is simple, quick and accurate to operate when carrying out mass measurement work, reduces the operation time and labor intensity, and better improves the labor productivity.
The Chinese patent application number is: CN202021738011.7, publication date: 2021, 2 month and 19 days' patent literature discloses a work piece bending radius detection device, relates to work piece bending radius detection technical field, including measuring work piece and benchmark ruler, the middle part of measuring the work piece and the one end butt of benchmark ruler, there is the dipperstick at the middle part of benchmark ruler through cardboard activity joint, the dipperstick is the cross setting with benchmark ruler, the measuring work piece is one of angle steel, channel-section steel, I-steel, H shaped steel and steel pipe, the width of dipperstick is greater than the width of benchmark ruler.
The measuring device of the two schemes can be used for measuring the inclination of the flange of the H-shaped steel, however, when the measuring device of the two schemes is used for measuring the H-shaped steel with thick specification and large specification, the problem of inconvenient measurement exists, and the circular arc fillet at the rolling connection part of the web plate and the flange also has an influence on the compaction positioning of the measuring device.
