Longitudinal shearing processing technology of soft cold-rolled sheet

Abstract

The invention belongs to the technical field of processing of cold-rolled sheets, in particular to a longitudinal shearing processing technology of a soft cold-rolled sheet. A guide device of the longitudinal shearing processing technology comprises a bottom plate, a slide seat, a vertical roll support, a vertical roll, bracket vertical columns, a pressing module and a reference module, wherein the upper end of the vertical roll support is fixedly connected with the lower end of each bracket vertical column, and the pressing module is arranged between the two bracket vertical columns; the reference module is arranged under the pressing module, and the pressing module is used for matching with the reference module to level the sheet; the reference module is used for providing the referenceafter pressing for the pressing module; the pressing module comprises a shear fork mechanism, a pressing roll, a pressing roll bracket, springs and slide blocks, and both ends of the shear fork mechanism are arranged on the two bracket vertical columns through the slide blocks; the pressing roll is arranged at the lower end of the shear fork mechanism. The longitudinal shearing processing technology has the advantages that while the sheet is positioned by the vertical roll through the shear fork mechanism, the pressing roll is driven to press the sheet; by combining with the reference module at the lower end of the sheet, the sheet can be flattened.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled sheet processing, in particular to a slitting process of soft-state cold-rolled sheet. Background technique [0002] The cold-rolled sheet is characterized by high requirements for dimensional accuracy and surface quality. Width accuracy is the main control point for dimensional accuracy. The width accuracy of the precision slitting line for cold-rolled sheet is required to be within ±0.005mm. The cold-rolled sheet after annealing is commonly known as soft-state cold-rolled sheet. In actual production, due to factors such as uneven hardness of the hot-rolled sheet, plate shape control deviation during cold-rolling and rolling, and installation accuracy deviation of soft-state shearing equipment, etc., The strip often deviates before entering the soft slitting shear axis, which leads to defects such as warping and inaccurate dimensions, so that the high performance requirements of the soft cold...
