Cutting and welding working table

Abstract

A cutting and welding working table on a rolling production line comprises a working table body, a front guide assembly, a material cutting assembly, a butt welding material press assembly and a rear guide assembly. The front guide assembly, the material cutting assembly, the butt welding material press assembly and the rear guide assembly are sequentially installed above the working table body, the working planes of the assemblies are located on the same plane, and the working center lines are located on the same straight line. The working table is level in belt material cutting end and good in butt welding quality, avoids damage to roller wheels caused by poor butt welding thickness and greatly improves working efficiency due to the fact that cutting and butt welding can be conducted in a line production mode.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a strip cutting and tailor welding workbench on a rolling production line. Background technique [0002] In the rolling production process, in order to complete the continuous production of rolling, the strips need to be spliced; in the past, the ends of the strips were cut flat by hand, and then placed on the flat site and directly welded and spliced ​​by argon arc welding; because the strips The unevenness and warping of the ends, coupled with the limitation of the flatness of the splicing site, cannot guarantee the flatness of the spliced ​​butt welded seam, resulting in thicker thickness of the tailor welded part; resulting in the thickened spliced ​​part passing through the upper and lower parts during subsequent rolling When there are two sets of rollers, because of the negative gap, it will affect the change of the gap between the rollers and cause damage ...

[0002] In the rolling production process, in order to complete the continuous production of rolling, the strips need to be spliced; in the past, the ends of the strips were cut flat by hand, and then placed on the flat site and directly welded and spliced ​​by argon arc welding; because the strips The unevenness and warping of the ends, coupled with the limitation of the flatness of the splicing site, cannot guarantee the flatness of the spliced ​​butt welded seam, resulting in thicker thickness of the tailor welded part; resulting in the thickened spliced ​​part passing through the upper and lower parts during subsequent rolling When two sets of rollers are used, due to the negative gap, it will affect the change of the gap between the rollers and cause damage to the rollers

At the same time, since the cutting and butt welding of strip materials need to be carried out in different places, the circulation of materials greatly reduces work efficiency
