Control method and device of servo electric cylinder press machine, electronic equipment and storage medium

Abstract

The invention relates to a control method and device of a servo electric cylinder press, electronic equipment and a storage medium, and belongs to the field of industrial automation. The method comprises the steps that the pressure value output by a servo electric cylinder press machine is obtained, and the servo electric cylinder press machine comprises an electric cylinder; calculating a pressure adjusting value according to the target pressure value and the pressure value; a displacement adjusting value is calculated according to a displacement variable quantity self-adaptive relational expression and the pressure adjusting value, and the displacement variable quantity self-adaptive relational expression is used for representing the corresponding relation between the pressure adjusting value and the displacement adjusting value; and the displacement adjusting value is determined as the displacement increment output by the electric cylinder, and the servo electric cylinder press is controlled according to the displacement increment. The pressure output by the servo electric cylinder press is adjusted by directly changing the deformation displacement of the pressed workpiece, and the influence of system damping in the control process of adjusting the output pressure through torsion can be avoided, so that the control precision is improved, and more accurate wide-range pressure control is realized.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to a control method, device, electronic equipment and storage medium of a servo electric cylinder press. Background technique [0002] The servo electric cylinder press is a modular product that combines a servo motor with an electric cylinder. The electric cylinder is used to convert the rotary motion of the servo motor into linear motion to output pressure. The traditional control method of the servo electric cylinder press is to use the servo motor torque mode to control the electric cylinder. The pressure adjustment value is calculated based on the target pressure value and the output pressure value of the servo electric cylinder press, and the servo motor is adjusted based on the pressure adjustment value. torque limiter. [0003] However, there is system damping in the process of the servo motor driving the electric cylinder, so that in the moving state of the electric cy...
