Problems solved by technology

[0003] In the existing main transmission device of the upper roller, when the main transmission device is set on the upper roller and the upper roller is pressed down to feed, and the main transmission device moves together with the upper roller, the main transmission device generally includes a planetary reducer, a cycloid pinwheel Reducer or harmonic reducer, etc.; some are only set as parallel shaft gear transmission at the output stage of the main transmission device, and four planetary reducers are driven by four motors, and four planetary reducers installed on the output shafts of the four planetary reducers A small gear drives the large gear directly connected to the upper roller. The output stage parallel shaft gear transmission adopts involute gear transmission. The volume of the output stage gear is large, and the axial dimension of the motor and the planetary reducer is long; When the device moves together with the upper roller, the output stage gear reduction box or the entire transmission device forms a centrally symmetrical structure with the upper roller. The frame bears the overturning torque of the main transmission device, that is, the reaction torque, the frame is designed to be tall and thick, and the cost is high

Abstract

The main upper roll driver for plate bending machine includes one speed reducer and one driving set. The speed reducer has big output gear fixed onto the upper roller directly or through a coupling, and input shaft connected to the output shaft of the driving set, which is a motor or an oil motor. The present invention features the speed reducer comprising gear box, and 1-5 stages of driving gears. The present invention has the features of low cost and small size.

Description

technical field [0001] The invention belongs to the field of forging equipment for bending metal plates—a plate rolling machine, and in particular relates to an upper roller main transmission device of a plate rolling machine. Background technique [0002] The existing plate rolling machine includes work rolls, movable frame, fixed frame, work roll pressure feeding device, main transmission device, bed, etc. In the main transmission device, there are two main transmissions for the upper roll and the main transmission for the lower roll. kind. In the existing main transmission device of the upper roller with pressure feeding of the upper roller, some main transmission devices are arranged outside the upper roller and connected with the upper roller through a universal coupling; some main transmission devices are arranged on the upper roller ; When the upper roll is the main drive, the lower roll is the passive roll or the auxiliary drive. [0003] In the existing main trans...
