[0001] The utility model relates to the technical field of bend angle detection, in particular to a bend angle detection device for square and rectangular steel pipes. Background Technique
[0002] During the production and use of square and rectangular steel pipes, bend angle detection is usually carried out. During the production process of steel pipes, bend angle detection can ensure that the geometric shape of the steel pipes meets the design requirements and avoid production quality problems caused by bend angle deviation. If square and rectangular steel pipes are used in construction, structures or other engineering projects, bend angle detection can ensure that the steel pipes can be correctly installed and connected to meet the design requirements and strength standards. Some industries or specific applications may have strict requirements for the bending angle, curvature radius or bending position of steel pipes, and bend angle detection is required to verify whether these parameters meet the requirements.
[0003] Under the existing technology, at present, square and rectangular steel pipe production enterprises generally adopt a bending degree detection method: Please refer to Figure 1 As shown in the figure, first place the straight ruler 2 flat on the bending part of the steel pipe 1. One person holds the straight ruler at a position 1.5 meters away from the bending with his hand, and another person inserts feeler gauges with different thicknesses (not shown in the figure) into the gap between the end of the steel pipe 1 and the straight ruler 2. The third person measures the gap height L; the bending degree at the 1.5-meter bending part of the steel pipe 1 can be obtained.
