Down-adjustment type high-speed thin sheet longitudinal shearing machine

Abstract

The invention provides a down-adjustment type high-speed thin sheet longitudinal shearing machine, belongs to the technical field of longitudinal shearing machines. The down-adjustment type high-speedthin sheet longitudinal shearing machine comprises a left side machine frame, a right side machine frame, an upper cutter shaft and a lower cutter shaft, wherein the upper cutter shaft and the lowercutter shaft are arranged between the left side machine frame and the right side machine frame, upper side bearings are fixedly arranged in the left side machine frame and the right side machine framecorrespondingly, the upper side bearings are arranged at the two ends of the upper cutter shaft in a sleeving mode, the upper cutter shaft is fixed between the left side machine frame and the right side machine frame through the upper side bearings, lead screws which are arranged straightly are movably supported in the left side machine frame and the right side machine frame, lead screw nuts areconnected with lead screws in a sleeving mode, a lower cutter holder is fixed on the lead screw nuts, a lower side bearing is arranged in the lower cutter holder, the lower cutter shaft is arranged between the left side machine frame and the right side machine frame through the lower side bearing, the lower cutter holder is driven by the lead screw nuts to slide on the left side machine frame or the right side machine frame, a worm and gear mechanism is further arranged on the left side machine frame and the right side machine frame, and the lead screws can move under the linkage action of theworm and gear mechanism. The down-adjustment type high-speed thin sheet longitudinal shearing machine has the advantages that precision of the longitudinal shearing machines can be improved, and convenience is brought to a user to use.

Description

technical field [0001] The invention belongs to the technical field of slitting machines, and in particular relates to a down-adjustment high-speed thin plate slitting machine. Background technique [0002] The slitting machine is a kind of sheet metal cutting equipment, which is suitable for longitudinal shearing of sheet metal, and finally cuts the sheet metal into narrow strips of required width. The quality of longitudinal shearing not only affects the quality of the metal strip obtained in this processing link, but also affects the progress of the next processing link. The error in the width of the metal strip and the lack of straightness of the metal strip will affect the geometric dimension accuracy of the product. In the traditional During the cutting process of the slitting machine, due to the unstable tension of the metal sheet during the feeding process, and when the metal sheet enters between the slitting blades in a loose state, it is difficult to ensure that th...
