Description

Technical Field

[0001] The utility model relates to the technical field of steel processing, in particular to a full-automatic H-shaped steel horizontal straightening machine. Background Art

[0002] H-shaped steel is a common structural steel material. It is widely used in construction, bridges, machinery manufacturing and other fields because of its advantages such as strong bending resistance in all directions, simple construction, cost saving and light structure. In the production process of H-shaped steel, the plate is usually cut and then welded into H-shaped steel by three plates (i.e., web and two flange plates). The assembly process uses an automatic welding machine for welding connection. Since the welding process can easily cause local bending and deformation of the two flange plates, the H-shaped steel needs to be corrected after welding to avoid the deformation of the steel affecting its use. The Chinese utility model patent with the authorization announcement number CN218049731U discloses an H-beam correction device, which can reliably clamp the H-beam to be corrected by placing the H-beam to be corrected in an I-shape on a support block and driving the pressure plate downward with the help of the electric push rod 2, and at the same time, the electric push rod 1 drives the correction plate 1 and the correction plate 2 to approach the inner concave structure of the H-beam, so that the floating web and the wing plate of the H-beam can be corrected simultaneously under the extrusion of the correction plate 1 and the support of the correction plate 2. During the correction process, the correction plate 2 can be conveniently extended and retracted by the action of the electric push rod 1, the spring rod and the connecting rod, thereby eliminating the tedious operation of frequently replacing the correction pressure block during the correction process of the H-beam, and greatly improving the correction efficiency of the H-beam. However, the prior art has the following problems: after the correction of one flange plate, it needs to be manually turned over and moved to the front end of the correction machine to correct the other flange plate again, which has high manual labor intensity and low efficiency.
