Die-cutting machine pressure regulation control method

Abstract

A die-cutting machine pressure regulating control method includes the steps: initial setting: inputting displacement needed by a pressure regulating device, the regulating distance corresponding to each pulse of a servo motor and a torque value corresponding to a displacement limit value of the servo motor; initial setting positioning: driving the servo motor to act, recording a lower limit position as a reference position when the displacement limit value is reached, and then returning the servo motor to an original position; setting the pressure regulating device to determine the number of increased pulses needed by the pressure regulating device relative to the reference position; driving the pressure regulating device to move and regulate pressure; reaching a preset position when the servo motor finishes the sum of the pulse number corresponding to the reference position and the needed increased pulse number, starting a control device for braking, stopping the pressure regulating device from moving, and finishing regulating the pressure. The reference position is firstly positioned, the needed increased pulse number is determined according to difference relative to the reference position by subsequent pressure regulating, so that the pressure can be rapidly and accurately regulated, and accumulated errors are avoided.

Description

technical field [0001] The invention relates to the technical field of die-cutting machines, in particular to a method for regulating and controlling the pressure of a die-cutting machine. Background technique [0002] In the actual die-cutting process, the die-cutting machine will often process without stopping for a long time. The high-frequency up-and-down die-cutting movement is repeated. The self-locking ability of the traditional pressure adjustment mechanism is poor. When affected by frequent movements, it will unconsciously Perceived displacement, resulting in pressure changes. However, the traditional pressure adjustment mechanism basically relies on the experience and judgment of the operator to adjust, and the accuracy is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure regulation control method for a die-cutting machine, which can efficiently and accurately adjust the die-cutting ...
