Title:
HEAVY-LOAD HIGH-PRECISION TRANSMISSION MECHANISM SUITABLE FOR METAL PLATE BENDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/040866
Kind Code:
A1
Abstract:
Disclosed in the present invention is a heavy-load high-precision transmission mechanism suitable for a metal plate bending device, comprising pressing arms, connecting rods, hinge supports, pressing arm height-adjusting assemblies and pressing arm height-adjusting driving assemblies. The pressing arms are symmetrically arranged at the top of a rack. The front end portion of each pressing arm facing an upper cross beam is hingedly connected to the upper cross beam by means of the connecting rod. A middle portion of each pressing arm or a rear end portion of each pressing arm facing away from the upper cross beam is hingedly connected to the rack by means of the hinge support. The rear end portion or the middle portion of each pressing arm is provided with one pressing arm height-adjusting assembly, and each pressing arm height-adjusting assembly is connected to one pressing arm height-adjusting driving assembly. The pressing arm height-adjusting driving assembly comprises an all-electric servo motor. The pressing arm height-adjusting assembly can swing or slide under the driving of the corresponding pressing arm height-adjusting driving assembly, thereby driving the pressing arms to rotate back and forth around the hinge supports and driving the upper cross beam to ascend and descend. According to the present application, the height-adjusting drive of an upper cross beam having heavy loads of 80 tons or above can be realized, the driving precision is high, the energy is saved, environmental friendliness is achieved, and the inverse kinematics is simple.
