Description

TECHNICAL FIELD

[0001] The utility model relates to H shaped steel processing technical field especially relates to a H shaped steel processing correction device. BACKGROUND

[0002] H-shaped steel processing is a complex and delicate process involving multiple links and steps. Hot-rolled H-shaped steel: The heated raw material enters the rolling mill for multi-pass rolling, gradually rolling the raw material into the shape of H-shaped steel. Welded H-shaped steel: The edge and waist are welded together on a continuous welding unit. The steel plate is cut and spliced according to the preset H-shaped steel section size, and then welded together to form H-shaped steel. The processing flow of welded H-shaped steel is more complex. Material selection and pretreatment: Select steel billets or steel plates that meet the requirements as raw materials and conduct strict inspection to ensure that their chemical composition, mechanical properties, etc. meet the production requirements. The raw material needs to be straightened before entering the production line to eliminate internal stress and bending. Cutting and flattening: Use a precision numerical control flame steel plate cutting machine to cut the steel plate. Pretreatment is required before cutting to remove the oxide layer on the surface of the steel plate and improve the density of the steel plate surface. After cutting, the steel plate or profile needs to be corrected. Steel plate butt joint: The steel plate butt joint uses semi-automatic precision cutting, and the butt welding uses semi-automatic submerged arc welding. The groove and its edge should be thoroughly inspected before welding, and ultrasonic inspection should be conducted to check for defects such as interlayer, cracks, and dirt. T-shaped part manufacturing: Assembled and formed on the full-automatic assembly machine on the H-shaped steel production line to ensure that the verticality of the T-shaped assembly web and flange plate meets the design requirements, and the assembly is temporarily fixed after assembly. H-shaped steel assembly: Assembled on the imported H-shaped steel production line, four hydraulic positioning systems clamp the upper and lower flange plates and the web of the H-shaped steel component for positioning, adjust the parallelism of the flange plates and the perpendicularity of the flange plates and the web, and then fixed and welded. H-shaped steel welding: Full-automatic submerged arc welding on the H-shaped steel automatic production line, welding with symmetrical welding sequence. The quality of the weld needs to be ensured during welding to avoid defects such as cracks and slag inclusion. H-shaped steel correction: Due to the heat generated during welding, it is difficult to release the welding stress deformation immediately, so the welded H-shaped steel needs to be corrected to ensure the parallelism of the flange plates. The correction is carried out on the correction machine on the H-shaped steel automatic production line. H-shaped steel measurement: After forming, the H-shaped steel needs to be measured to check whether the parallelism of the flange plates and the perpendicularity of the flange plates and the web meet the design requirements. H-shaped steel drilling, end face processing: After forming, drilling is carried out to ensure that the hole spacing meets the design requirements. End face processing is an important quality factor to ensure the butt joint of steel structures, and the parallelism of the two end faces needs to be ensured. Component shot blasting: After the component is completed and qualified, it enters the shot blasting process, mainly using imported eight-head full-automatic shot blasting machine for shot blasting. Component marking and storage: Mark the component number and position according to the process requirements. Pay attention to the protection of the rod when storing, and pay attention to the deformation of the components when stacking multiple components.

[0003] H-shaped steel processing correction is a key step to eliminate the deformation such as bending and twisting caused during processing, so as to ensure the dimensional accuracy and shape quality of H-shaped steel. Straightening machine correction: use a special straightening machine to correct the H-shaped steel. There are various types of straightening machines, such as parallel roller straightening machine, inclined roller straightening machine, etc. By adjusting the distance and angle of the straightening rollers, appropriate pressure is applied to the H-shaped steel to restore it to a straight state. Cold bending machine correction: for small amplitude bending, cold bending mechanical equipment can be used for correction. The bent part is fixed on the cold bending machine, and the original state is gradually restored by mechanical force. Hydraulic correction: for larger degree of bending, hydraulic equipment can be used for correction. Place the H-shaped steel on the hydraulic machine, and gradually restore it to its original state by hydraulic pressure. This method requires professional operators and equipment, and safety should be paid attention to during operation.

[0004] During H-shaped steel processing correction, it is necessary to ensure the correction effect and simultaneously correct the inner and outer sides of the H-shaped steel. However, the traditional correction method cannot simultaneously correct the inner and outer sides of the H-shaped steel, but only extrudes the outer side of the H-shaped steel.
