Four-point multi-link pressing machine adopting double-servo drive

Abstract

The invention discloses a four-point multi-link pressing machine adopting double-servo drive, belongs to the technical field of forging and pressing machinery, and aims at solving the problems that the needs of high power and high torque are difficultly met by a servo motor, a synchronous control error exists in the servo motor, and the effective output capacity of a servo pressing machine is reduced due to a backlash of an engagement gear in a speed reduction system, in the prior art. The four-point multi-link pressing machine adopting double-servo drive comprises a machine body, a downwards-moving slide block located in the machine body and sliding up and down, a planetary gear speed reduction device fixed to the upper end of the machine body, an auxiliary speed reduction unit connectedwith the planetary gear speed reduction device, a power input unit connected with the auxiliary speed reduction unit, two floating lead slide blocks connected with the power input unit and symmetrically arranged in the front-rear direction, and a double-symmetrical elbow lining mechanism, wherein the power input unit is of a double-symmetrical input structure; the upper parts of the sidewalls of the floating lead slide blocks are connected with the power input unit; and a power input end of the double-symmetrical elbow lining mechanism is connected with the lower parts of the sidewalls of thefloating lead slide blocks, and a power output end is connected with the downwards-moving slide block, and drives the downwards-moving slide block to relatively move or reversely move relative to a workbench.

Description
