Roller type plate leveling machine

Abstract

The invention discloses a roller type plate leveling machine. An upper roller frame is arranged above a lower roller frame, a moving beam is arranged between the upper roller frame and the lower roller frame, hydraulic telescoping cylinders are arranged at the bottom of the upper roller frame, telescopic heads of the hydraulic telescoping cylinders are connected with the moving beam, a plurality of upper operating rollers are mounted at the bottom of the moving beam, a plurality of lower operating rollers are arranged on the lower roller frame, the upper operating rollers and the lower operating rollers are staggered, and two ends of each of the upper operating rollers and the lower operating rollers are connected with corresponding power transmission mechanisms. A plurality of first uppersupporting rollers and a plurality of second upper supporting rollers are arranged between the upper operating rollers and the moving beam, and a plurality of first lower supporting rollers and a plurality of second lower supporting rollers are arranged between the lower operating rollers and the lower roller frame. The lower roller frame is fixedly connected to one end of each guide column, andthe other end of each guide column penetrates the moving beam to be fixedly connected with the upper roller frame. Problems of nonuniformity in stress of two ends of operating rollers, low leveling accuracy, small contact area of supporting rollers and the operating rollers, low supporting strength and poor stability of plate leveling machines in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of leveling equipment, and relates to a roller-type plate leveler. Background technique [0002] The basic principle of roller leveling is to selectively extend each part of the material. Below the yield point of the material, the shorter part of the stone fiber is elongated in proportion to obtain a consistent fiber length, so that the material passes through the leveling machine. Do cyclic up and down bending with a smaller radius of curvature to elongate the shorter material fibers. When the workpiece to be leveled moves toward the exit of the leveling machine tool, the amplitude of the up and down bending gradually decreases to eliminate the need for machine tool leveling. Material deformation caused by severe bending at the entrance, when all the fiber lengths on the workpiece to be leveled are almost the same, the purpose of leveling is achieved; however, only one work roll is connected to the power tr...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a roller-type plate leveler, which solves the problem of uneven force on both ends of the work rolls of the plate leveler in the prior art, low leveling accuracy, and the contact area between the support roll and the work roll. Small size, low support strength and poor stability
