The Composition Of The Electric Control System Of The Die Forging Machine

Nov 07, 2017

Usually, in the selection of the design scheme of die forging machine transmission system, many factors must be considered, including not only the specific forging heat treatment production line requirements, but also the process requirements, combined with the operation cost and other factors. So, what are the components of the electrical control system of the die forging machine?

In general, the automatic control system of the die forging machine mainly includes programming unit, programmable controller, industrial site bus, touch screen, testing components and printers on the press, etc. In this system, the remote I/O station mainly includes two sets of ET200M, located in the PLC cabinet and the operation box, with the main station constitutes the main part of the communication network of the basic automation system.

In this control system, one of the components that plays an important role is the host frame in the PLC cabinet. It mainly includes a power supply module, a CPU module, two position input modules and six digital input modules. The main function of the module of PLC cabinet is to deal with each button and various switch signal detection components signal, so as to realize the control of single and inching of die forging machine slider.

In addition, the remote I/O station rack module has two aspects. On the one hand, it can measure the various analog quantity of the hydraulic station, such as the liquid level, oil circuit pressure and oil temperature signal of the tank. On the other hand, the signal of the temperature monitoring points of the die forging machine is measured, including the crankshaft temperature and the main motor winding temperature.

In addition, for the die forging machine, the touch screen and remote I/O station are mainly connected with the help of PROFIBUS DP. The orientation module is capable of measuring the adjustment of the crankshaft angle, top material height and height adjustment condition after receiving the signal of the rotary encoder.
