The invention relates to a pressure roller device on a mechanical straightening machine. The pressure roller device comprises lifting slide block seats mounted on the frame of the straightening machine and on both sides of a main straightening roller; pressure roller components are mounted on the lifting slide block seats on both sides respectively; and each pressure roller component comprises a pressure roller shaft and an upper pressure roller mounted at the front end of the pressure roller shaft, and the upper pressure rollers extend out of the lifting slide block seats. The pressure roller device is characterized in that steps are arranged on the external surfaces of the upper pressure rollers to form first steps and second steps, and external surfaces of the first steps and the second steps are conical surfaces; the first steps are arranged on one sides of the front ends of the second steps, which are close to minitype H sections or standard H sections, and the maximum diameter of the external conical surface of each first step is smaller than the minimum diameter of that of each second step. The pressure roller device not only straightens the standard H sections and minitype H sections but also can be used conveniently and simply without needing to replace the upper pressure rollers.
Description
technical field [0001] The invention relates to a pressing roller device on a mechanical straightening machine, in particular to a pressing roller device used on a mechanical straightening machine which can straighten both standard H-shaped steel and extra-small H-shaped steel. Background technique [0002] With the development of the economy, steel structure buildings are more and more used, and the production of steel structure parts is also more and more using modern mechanical equipment. H-beam is the most commonly used steel structure in steel structure buildings, and its production is mainly composed of splicing, welding, correction and other parts. The mechanical straightening machine is mainly used to correct the deformation of the H-shaped steel wing plate. Especially in chemical equipment and boiler equipment, a large number of steel structure parts are used as welding frame parts. Among these steel structure parts, the material is manganese plate with grade Q345,...
