Real-Time Monitoring for Four-Column Hydraulic Presses: Alternating Feed and Smart Control
An alternating feed unit and an intelligent control system for four-column hydraulic presses: industrial PC, HMI, PLC, hydraulics and data acquisition linked over RS-485 to monitor pressure, valve states and positions.
The original article describes two add-ons that improve the efficiency and safety of a four-column hydraulic press: an alternating feed unit and an intelligent control system.
Alternating feed unit
- A feed platform level with the press opening, with two horizontal rails.
- A power box between the rails supplies two cables to heated pads.
- A feed cart on the rails carries the heated pads and material; a support frame is welded at the far end.
- Result: alternating, continuous feeding, higher output, less manual work and safer handling of live, hot parts.
Intelligent control and monitoring
The system consists of an industrial PC, HMI, PLC, the hydraulic system and a data-acquisition unit. The data-acquisition unit reads the hydraulic outputs and feeds the PLC; the PLC communicates both ways with the PC and HMI over an RS-485 bus.
Operators can see working pressure and other data, the on/off state of each solenoid valve and the position of every moving part in real time, and make settings on the HMI.
See the hydraulic presses category, e.g. the AS205H four-column hydraulic hot press.
