Lower roll driving mechanism of down-adjusting plate bending machine

Abstract

The invention discloses a lower roll driving mechanism of a down-adjusting plate bending machine, relates to forging machinery, and in particular relates to the technical field of lower roll transmission of a plate bending machine. The lower roll driving mechanism comprises a lower roll and two brackets, wherein the two brackets are supported below the left and right ends of the lower roll respectively; the left and right brackets are provided with a driving mechanism respectively, and comprises a hydraulic motor, a motor gear, an intermediate transmission gear and a lower roll gear; the lower roll gear is fixedly connected with the top end of the lower roll; the hydraulic motor is fixed on the bracket; an output end of the hydraulic motor is connected with a transmission shaft; an output end of the transmission shaft is fixedly connected with the motor gear; the intermediate transmission gear is arranged between the motor gear and the lower roll gear; the motor gear and the lower roll gear are meshed with the intermediate transmission gear respectively; and the motor gear, the intermediate transmission gear and the lower roll gear are arranged on the outer side of the bracket. The lower roll driving mechanism of the down-adjusting plate bending machine disclosed by the invention has a relatively compact whole structure, occupies a relatively small space, and avoids inconvenience in mounting and adjusting.

Description

technical field [0001] The invention relates to forging machinery, in particular to the technical field of lower roll transmission of a plate bending machine. Background technique [0002] There are many kinds of transmission technologies for the lower rollers of the existing down-adjustable three-roller plate bending machine. The mechanical transmission of the lower rollers connected with the reducer through the directional coupling has a complex structure and takes up a lot of space; the two lower rollers are driven by the planetary reducer motor mechanism. , the installation of the reducer needs to be considered, and the relevant structures need to be increased accordingly; the two lower rollers are driven by the same transmission device, and the speed of the two rollers is the same, which cannot offset the cross-layer force generated by the steel plate during the rolling process; the lower roller does not have a drive Most of them are driven rollers, which are inconvenie...
