Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like figure 1 As shown, the present invention includes a console 1, a dedicated controller 2, an electric control cabinet 3 equipped with an actuator, a resolver 5, an encoder 6, a safety double valve 7 and a proximity switch 8.

[0034] The console 1 and the dedicated controller 2 are electrically connected, and the console 1 sends the operation and stop signals of the press to the dedicated controller 2 . When there is no abnormality in the feeding device 10, the safety light curtain 9 and the safety double valve 7, the press and its external equipment operate according to the signals sent by the console, otherwise they cannot be started.

[0035] The resolver 5 is connected to the crankshaft of the press through a flange or coupling, and is used as a sensor of the crankshaft angle / slider stroke of the press, and transmits the collected crankshaft angle / slide...

Abstract

An automatic control system of mechanical press features that the rotary transformer is used as the sensor of crankshaft angle and slide blockí»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...
