A guide device for longitudinal shearing of soft cold-rolled sheet

Abstract

The invention belongs to the technical field of longitudinal shearing equipment for cold-rolled sheets, and particularly relates to a longitudinal shearing guide and guard device for a soft cold-rolled sheet. The device comprises a bottom plate, sliding bases, vertical roller supports, vertical rollers, bracket columns, pressing modules and reference modules; the upper ends of the vertical rollersupports are fixedly connected with the lower ends of the bracket columns, and the pressing modules are arranged between the two bracket columns; the reference modules are arranged below the pressingmodules, and the pressing modules are used for cooperating with the reference modules to flatten the sheet; the reference modules are used for providing a reference after pressing for the pressing modules; each pressing module comprises a scissor fork mechanism, a pressing roller, a pressing roller bracket, a spring and sliding blocks, the two ends of each scissor fork mechanism are installed on the two bracket columns through the corresponding sliding blocks; the lower end of each scissor fork mechanism is provided with the corresponding pressing roller. According to the device, through the scissor fork mechanisms, the pressing rollers are driven to press the sheet while the sheet is positioned by the vertical rollers, and through the combination of the reference modules at the lower endof the sheet, the sheet is flattened at last.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled sheet slitting equipment, in particular to a soft-state cold-rolled sheet slitting guide device. 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...

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-rolled sheet cannot be guaranteed, resulting in a great loss of yield

However, due to the thin thickness of the soft cold-rolled strip, the positioning accuracy of the generally used guide device is poor at present, and the structure is heavy, and cannot be unilaterally adjusted. A device for quality problems such as deviation, warpage, and inaccurate dimensions that occur during the shearing production process
