Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an H-shaped steel shaping and straightening machine. Background Art

[0002] H-shaped steel is a profile with a cross-section shape similar to the letter H. H-shaped steel includes a web and a flange plate. The inner and outer sides of the flange plates are parallel or nearly parallel, and the ends of the flange plates are at right angles. Determined by the shape, the section modulus, moment of inertia and corresponding strength of H-shaped steel all have good performance, so H-shaped steel is widely used in metal structures with different requirements.

[0003] During the heating, rolling, cooling and transportation process, H-shaped steel usually deforms due to external forces or temperature changes. The verticality of the two sets of flange plates and the web plate in the H-shaped steel and the flatness of the flange plates directly affect the product qualification rate of the H-shaped steel. Therefore, a straightening machine is required to detect and straighten the H-shaped steel. The existing straightening machine generally includes a machine body and straightening rollers. There are multiple sets of straightening rollers. The straightening rollers are evenly distributed and abut against the web and flange plates of the H-shaped steel. Under the action of the machine body, the straightening rollers rotate, thereby squeezing and straightening the H-shaped steel.

[0004] In view of the above phenomenon, the inventor believes that after the H-beam passes through the straightening machine, the staff needs to use the detection tool to re-inspect the H-beam to detect the unqualified parts of the H-beam. Since the H-beam is long, the staff spends time and effort in the detection process, and it is easy to make mistakes. For this reason, the inventor invented a shaping and straightening machine that can perform online detection of H-beam. Utility Model Content

The oil seeps out from the through hole of the groove and adheres to the surface of the elastic rubber ball. The elastic rubber ball rolls and rubs on the moving H-shaped steel. At this time, the oil on the surface of the elastic rubber ball will adhere to the groove surface of the H-shaped steel. The groove surface of the qualified H-shaped steel will have uniform oil traces, while the groove surface of the unqualified H-shaped steel will have uneven oil traces. The unstraightened parts of the H-shaped steel will be squeezed or out of contact with the elastic rubber ball. When the H-shaped steel is squeezed with the elastic rubber ball, the contact area between the elastic rubber ball and the groove surface of the H-shaped steel increases, so the width of the oil trace increases. When the H-shaped steel is not in contact with the elastic rubber ball, no oil traces will appear on the surface of the H-shaped steel, so that the unqualified parts of the H-shaped steel can be quickly determined.

When the H-steel is squeezed with the elastic rubber ball 215, the contact area between the elastic rubber ball 215 and the groove surface of the H-steel increases, so the width of the oil trace increases. When the H-steel is not in contact with the elastic rubber ball 215, no oil trace will appear on the surface of the H-steel. The straightening machine in this embodiment can quickly detect the H-steel undergoing straightening operation, thereby saving the labor of the staff.
