How to Design Hydraulic Press Automation Systems

Hydraulic presses are indispensable tools for manufacturers, helping them craft a variety of parts. From molding auto parts to fabricating panels for appliances, hydraulic presses have applications across numerous industries.

However, manual operation can be slow and inefficient. Therefore, many manufacturers turn to automation in order to accelerate production and enhance quality.

Designing the Control System

Hydraulic presses offer program flexibility and the capacity to modify dies, pressure, stroke speed or process position without replacing the entire press. This feature extends the life of a press while encouraging customization and innovation in production.

One of the key advantages of a hydraulic press is its capacity for full tonnage throughout its stroke, enabling it to produce any part with exact force. This precision can be especially helpful in deforming processes requiring constant pressure throughout.

Pressing operations are intricate, demanding processes that necessitate precise control. That is why having an effective control system is paramount to any hydraulic press automation project's success.

SMG, an industrial stamping company that manufactures automotive parts, needed a modern automation system to enhance product consistency and reduce cycle times. They sought out an advanced automated setup that could be designed and installed quickly.

Designing the Hydraulic System

Hydraulic presses are an indispensable industrial tool used in many sectors such as manufacturing, robotics, steel processing and logging. Their basic principle relies on using incompressible fluid to transmit force from one point to another.

The most basic hydraulic circuit consists of a reservoir, pump, relief valve, 3-way directional control valve and single acting cylinder. When the control valve is shifted in either direction it causes oil to flow into the cylinder while simultaneously returning it to its original reservoir.

In production, the system automatically reverses the direction of press motion by measuring pressure on the ram. This guarantees consistent depth within the press, increasing part quality and prolonging machine life. You can easily alter stroke speed and length with ease using your touch-screen controller during operation.

Designing the Electrical System

The Electrical System is an essential element of your hydraulic press automation system. It should include a reliable power source that supplies energy to the press while reducing potential risks such as injury or equipment malfunctioning.

Safety controls are essential for machine dependability and a low total cost of ownership. Donald Engineering provides the components and expertise to design an effective safety system that safeguards your investment.

Delta's specialized solution utilizes the PC-Based Host Motion Controller MH1 Series and Delta AC Servo Drive & Motor ASDA-A2 Series to efficiently regulate motion, load and flow. This improves processing stability, minimizes manual labor requirements and simplifies operation for high quality industry applications.

This system also features a CAT 4 two-hand anti-tie down safety relay to guarantee operator's hands are out of the work area when cycle initiators activate. All wiring is terminated to spring cage-style terminals for vibration-resistant connections and easier troubleshooting.

Designing the Control Panel

One of the most essential elements in hydraulic press automation systems is the Control Panel. This metallic structure houses power circuits and other electrical devices that assist in controlling mechanical machinery in factories or plants.

A control panel's primary role is to guarantee reliable and secure operation for industrial operators in an industry or building. It contains circuit breakers, transformers for changing voltage levels according to need, terminal blocks for housing different voltage levels and various PLCs and relays that assist with logical control system operation.

Typically, it is designed to meet specific standards for usage and application. Its body is typically either aluminum or stainless steel and can be enclosed or open to protect equipment from external conditions and hazardous materials.
