Device for preventing longitudinal wary cambered surface generated by cold roll forming

Abstract

The invention belongs to cold roll forming equipment and particularly relates to a device for preventing a longitudinal wary cambered surface generated by cold roll forming. The device is characterized in that a carrier roller device for supporting the bottom surface of processed workpirces is arranged on a stand corresponding to the position of an outlet end of a rolling port of each rolling mill in a forming section S, wherein the carrier roller device consists of a transverse plate, a swing arm, support seats, a swing arm shaft, a carrier roller, a carrier roller shaft, an adjusting bolt and a bracket; the adjusting bolt for adjusting the lifting height and transverse movement of the carrier roller is arranged on the bracket; the top end of the adjusting bolt is in contacted connection with the bottom surface of a carrier roller slot; the bottom end of the adjusting bolt penetrates through adjusting bolt hole and extends and exposes out of a top plate of the bracket; and a plurality of adjusting nut holes for adjusting the transverse positions, which are matched with the adjusting bolt, are arranged in a top plate surface of the bracket. The device disclosed by the invention is reasonable in design and compact in structure; according to the device, the defect of longitudinal wavy cambered surface is prevented and the rigidity and the strength of a box plate are enhanced; in addition, the device has the advantages of attractiveness in appearance, high production efficiency, higher convenience for operation and use and the like.

Description

technical field [0001] The invention belongs to cold-bending forming equipment, in particular to a device for preventing longitudinal wavy arc surfaces from being produced by cold-bending forming. Background technique [0002] At present, with the rapid development of the economy, large-scale mechanical products have also emerged as the times require, such as large trucks, heavy trucks and car trains. , it needs to be manufactured with a large box board size. In order to strengthen the rigidity of the box plate, people design longitudinal grooves with convex or concave cross-sections on the box plate. At present, the box plate has to be stamped into convex or concave longitudinal grooves by a press such as a stamping machine; the above-mentioned stamping method is laborious and laborious, and the production efficiency is low; With the development and continuous progress, people have widely used the cold bending forming production line of the rolling mill. Although signific...

Problems solved by technology

At present, the box plate has to be stamped into convex or concave longitudinal grooves by a press such as a stamping machine; the above-mentioned stamping method is laborious and laborious, and the production efficiency is low; With the development and continuous progress, people have widely used the cold bending forming production line of the rolling mill. Although significant progress has been made in production efficiency, in the cold bending forming, the longitudinal wave-shaped arc surface is often produced on the top surface of the longitudinal groove. Defects, which are caused by the unbalanced longitudinal film strain of the edge retreat part and the web part in this section process, especially in the cold bending forming process of large-sized box panels, due to the fact that there is a With multiple rolling mills, whenever the rolled slab passes through the transition section between two adjacent rolling mills, due to the weight of the rolled slab, it will inevitably cause the rolled slab to fall downwards, resulting in a longitudinal wavy arc surface Defects, this longitudinal wavy arc surface defect is not conducive to the improvement of the rigidity and strength of the box board, but also affects the appearance of the product
