Problems solved by technology

[0003] In the past, the operator's experience was used to tentatively send instructions to the clamp rod position control device to control the clamp rod position. This operation is cumbersome, with low accuracy and stability, and its forging control self-adaption ability and degree of automation are relatively low. Low, if the position of the tong lever of the operating machine cannot adapt to the change of the center of the forging in time, it may cause damage to the equipment or damage to the forging, or greatly shorten the service life of the equipment itself

Abstract

The invention provides a self-adaptive centering control system and method for clamp rods of a large manipulator. The system comprises a large manipulator body, a PLC control system, an HMI man-machine interface, clamp rod inclination units, a clamp rod lifting unit and a clamp rod translation unit, wherein the HMI man-machine interface is in communication connection with the PLC control system; the clamp rod inclination units, the clamp rod lifting unit and the clamp rod translation unit are in electric signal connection with the PLC control system; and the HMI human-machine interface storesforge piece models and centering position data, corresponding to the forge piece models, of the clamp rods of all passes. According to the self-adaptive centering control system and the method for theclamp rods of the large manipulator, the PLC control system is used for determining the centering range in each direction required by the clamp rods under the current pass according to the model parameters of forge piece products and the current forging pass, so that the centering positions between the clamp rods and the forge pieces in batch forging can be kept in real time in a self-adaptive manner, accuracy of performance quality of the forge pieces and stability of mechanical equipment are guaranteed, and the intelligent level of forging control of the large manipulator body is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of manipulators for free forging, and in particular relates to an adaptive centering control system and method for a large-scale manipulator clamp bar. Background technique [0002] The large-scale forging manipulator is the basic equipment in the field of modern high-end forging, which is especially critical for improving forging efficiency and forging quality. In the forging process of each pass of large forgings, due to the unevenness of the force on the forgings and the ductility of the forging press during forging, the relative position of the clamp rod of the large manipulator that clamps the forgings and the body of the manipulator is in a certain position. in the process of dynamic change. This requires that the position of the clamp rod of the manipulator can be adjusted in real time to meet the requirement that the center position of the forging is always within the range of t...
