Cold rolling mill with leveling mechanism

Abstract

The invention discloses a cold rolling mill with a leveling mechanism, and particularly relates to the field of cold rolling mills. The cold rolling mill comprises a lower rack and rollers, roller columns are fixedly installed at the top of the lower rack, roller shafts are movably installed on the surfaces of the roller columns, an upper rack is fixedly installed at the top of the roller columns, an upper leveling box is fixedly installed on the side face of the upper rack, a first leveling column is fixedly mounted at the bottom of the upper leveling box, and an upper leveling plate is fixedly mounted at the bottom of the first leveling column. By arranging a leveling device, due to the fact that a steel plate is cylindrical during rolling, the steel plate is extruded unevenly during extrusion, the steel plate is produced and machined incompletely, and consequently the machining cost loss is caused, the leveling device can automatically level the steel plate after the steel plate is rolled, so that unevenness is prevented, the problem of the machining cost loss is avoided, the problem of low machining efficiency is solved, the machining efficiency is improved, and meanwhile, the evenness of the steel plate is improved.

Description

technical field [0001] The invention relates to the technical field of cold rolling mills, more specifically, the invention relates to a cold rolling mill with a leveling mechanism. Background technique [0002] The cold-rolling mill is a machine and equipment that makes the grade I hot-rolled Q235 round steel cold-drawn and cold-rolled into a spiral-shaped steel bar. The warp and weft directions are cold worked at the same time. [0003] At present, the cold rolling mill is used to extrude and shape steel bars. It is an important device to roll steel bars into steel plates. When the rolls are used, because the rolls are cylindrical, the steel plates will be extruded unevenly during extrusion. The production and processing of the steel plate is incomplete, resulting in the loss of processing cost and low processing efficiency. [0004] In addition, when leveling the steel plate, the steel plate is squeezed up and down by the leveling device, and then leveled. During the ex...

Problems solved by technology

[0003] At present, the cold rolling mill is used to extrude and shape steel bars. It is an important device to roll steel bars into steel plates. When the rolls are used, because the rolls are cylindrical, the steel plates will be extruded unevenly during extrusion. The production and processing of the steel plate is incomplete, resulting in the loss of processing cost and low processing efficiency

[0004] In addition, when leveling the steel plate, the steel plate is squeezed up and down by the leveling device, and then leveled. During the extrusion, because the steel plate will rub against the leveling plate, it will be damaged during long-term work. Cause friction to generate high temperature, damage the leveling device and fail to work, thereby reducing processing efficiency
