Electric control system of isothermal die-forging hydraulic machine

Abstract

The invention discloses an electric control system of an isothermal die-forging hydraulic machine, which relates to the technical field of automatic control on forging hydraulic machine. The electric control system is characterized by comprising an upper computer, a master station unit, a machine body slave station unit, a power slave station unit, a displacement transducer and a DP-COUPLER module, wherein the DP-COUPLER module is respectively and electrically connected with the master station unit, the machine body slave station unit and the upper computer; the machine body slave station unit is connected with the power slave station unit; and the displacement transducer is provided with a PROFIBUS-DP bus interface, and is connected with the power slave station unit through a PROFIBUS-DP bus. By virtue of the PROFIBUS-DP bus, a wiring structure of the electric control system of the isothermal die forging hydraulic machine is simplified, and the speed of data processing is enhanced.

Description

technical field [0001] The invention relates to the technical field of automatic control of forging hydraulic presses, in particular to an electric control system for isothermal die forging hydraulic presses. Background technique [0002] At present, the forging and pressing forming process of aluminum alloy wheels is a relatively demanding processing technology. In the forging process of aluminum alloy wheels, isothermal forging hydraulic presses are often used to forge aluminum alloy wheels, but people use it for a long time During the process, it was found that since the electronic control system of the traditional isothermal die forging hydraulic press mostly adopts a distributed control system, this system has the following defects: Since the I / O interface is non-digital, signal distortion or It is a phenomenon of loss, which greatly affects the objectivity of the judgment results of the control system. At the same time, because the signal transmission standards between...

[0002] At present, the forging and pressing forming process of aluminum alloy wheels is a relatively demanding processing technology. In the forging process of aluminum alloy wheels, isothermal forging hydraulic presses are often used to forge aluminum alloy wheels, but people use it for a long time During the process, it was found that since the electronic control system of the traditional isothermal die forging hydraulic press mostly adopts a distributed control system, this system has the following defects: Since the I / O interface is non-digital, signal distortion or It is a phenomenon of loss, which greatly affects the objectivity of the judgment results of the control system. At the same time, due to the inconsistent signal transmission standards between the various components of the electronic control system, the complexity of the wiring layout is greatly increased.
