Automatic control system of mechanical press

Abstract

An automatic control system of mechanical press features that the rotary transformer is used as the sensor of crankshaft angle and slide block's stroke, its encoder is the sensor of die height regulation, and the minimal single-chip computer system with the special control software is used for the logic control to overall units of mechanical press and their functions. Its advantages are simple structure and high reliability.

Description

technical field [0001] The invention relates to an automatic control system of a mechanical press. Background technique [0002] At present, the control system of the mechanical press generally adopts the method of discrete components, such as using a mechanical cam or an electronic cam as the crank angle / slider stroke sensor of the press, and the control logic is realized by PLC or relay. Due to the frequent action of the press, there are many logical nodes realized by the relay, which leads to an increase in failures. Although the use of PLC reduces some intermediate relays, due to the relatively high cost, the lack of a friendly man-machine interface, and the computing performance of the PLC Poor, low speed, difficult to implement some special control algorithms, so it is inconvenient to adjust and control the press, and the control effect is not ideal. Therefore, people urgently need a kind of automatic control system specially for mechanical press. Contents of the in...
