Disc shears and control system

Abstract

The invention provides a disc shear and a control system. The disc shear comprises a rack and an upper cutter roll and a lower cutter roll which are arranged on the rack; the rack comprises a fixed rack and a movable rack, one end of the upper cutter roll and one end of the lower cutter roll are rotatably arranged on the fixed rack, the other end of the upper cutter roll and the other end of the lower cutter roll are detachably and rotatably connected with the movable rack, and the structures of the upper cutter roll and the lower cutter roll are same; the upper cutter roll comprises a spindleand an outer spindle sleeve arranged on the spindle in a sleeving manner, an expanding sleeve is arranged at the free end of the upper cutter roll, and stopping blocks are arranged at the periphery of the expanding sleeve in the circumferential direction at intervals; and the movable rack is provided with a bearing sleeve matched with the free ends of the upper cutter roll and the lower cutter roll, a locking ring is arranged at the outer end of the bearing sleeve, and abutting blocks which are arranged at intervals are arranged on the inner wall of the locking ring in the circumferential direction. The expanding sleeve drives the locking ring to abut against the end face of a cutter ring gasket to achieve quick positioning and locking of annular cutters, interlocking control is set to ensure that displacement does not occur in the running process, the annular cutters can be reliably replaced, and the spacing distance among all groups of the annular cutters can be adjusted in time.

Description

technical field [0001] The invention relates to a strip cutting system, in particular to a device system for cutting strips wound into rolls into narrow strips whose width meets market requirements. Background technique [0002] The strip is provided by the upstream equipment rolling mill and cleaning line equipment. Generally speaking, the width of the strip required by market customers is small and different, which requires cutting the wide strip into narrow strips. The equipment to complete the cutting and dividing task is a disc shear or a roller shear, that is, ring knives are set on the upper knife roll and the lower knife roll, and the strip is cut when it passes between the two ring knives. Since the width of the raw material coil is usually determined, and the width of the strip required by downstream customers is different, in order to improve the utilization rate and processing efficiency of the raw material coil, the coil material is usually cut into at least two...

Problems solved by technology

What's more serious is that arranging multiple sets of ring knives on the knife roller requires a longer axial length of the guide roller. If the cantilever beam structure is used to install the knife roller on the frame, it will inevitably lead to the acceptance force of the overhang section. The difference in the final winding degree is huge. For high-precision thin-walled copper strips, it is difficult to cut more than two cuts, that is, there is no distance between the two ring knives in the ring knife set far away from the frame. Achieve a reliable and stable shear fit
