Movable profile steel correction device and correction method of profile steel

Abstract

The invention relates to a movable profile steel correction device. The movable profile steel correction device comprises a base for placing profile steel and at least one correction mechanism arranged on the base; the correction mechanism comprises a supporting frame and a stamping device fixed to the supporting frame; the supporting frame is slidably arranged on the base; the stamping device comprises a horizontal fixed rod, at least one hydraulic machine fixed to the fixed rod and a correction plate; the fixed rod is detachably fixed to the supporting frame; the hydraulic machines are longitudinally fixed to the lower end of the fixed rod; and the correction plate is arranged below telescopic rods of the hydraulic machines and is positioned above the profile steel, and the correction plate is driven to press the profile steel downwards to carry out correction through the extension of the telescopic rods of the hydraulic machines. According to the movable profile steel correction device, the wraped and deformed profile steel can be smoothly placed on the base, and suspended downward-pressing correction is carried out on a plurality of bending parts of the profile steel step by step through the movable correction mechanism, the correction is convenient, and the correction effect is good.

Description

technical field [0001] The invention relates to the field of calibration equipment, in particular to a movable profiled steel calibration device and a profiled steel calibration method. Background technique [0002] Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size, including H-shaped steel, I-beam and channel steel. Sectional steel is widely used in engineering construction because of its reasonable distribution of aspect ratio of cross-sectional size according to different purposes. It has excellent mechanical properties and superior performance. In the actual construction process, when the uneven external force such as vibration or impact on the section steel is too large, it often causes the section steel to warp and deform. After the project construction is completed, the section steel obtained after dismantling cannot be directly applied to the next project construction due to deviations in shape and size.

Problems solved by technology

However, in the actual correction process of the shaped steel, due to the large curvature of the deformed shaped steel, when one end of the shaped steel is stamped and corrected, the other end of the shaped steel is suspended outside the base, and the unstable center of gravity often makes it difficult to place the shaped steel on the base. Stamping calibration, inconvenient calibration, poor calibration effect
