4. Research and development of special control systems.
Most existing hydraulic presses are controlled by PLC, but servo hydraulic presses are controlled by hydraulic and speed closed-loop programs, which require large amounts of computation, so ordinary PLCs are difficult to meet the needs. The control system of the servo hydraulic press is controlled by industrial PC, so a special control system must be developed.
5. Forming process optimization based on servo hydraulic presses.
The materials and shapes of each stamping part are different, resulting in completely different stamping processes. For example, in the silent blanking process, the control of the speed change point is the key; in the reverse extrusion forming of magnesium alloy cup-shaped parts, the slider needs to experience 4 different speeds in one working cycle, and the extrusion process is still under constant pressure control. Therefore, the servo hydraulic press can only play its superiority when combined with various forming process optimizations. It is very important to study the forming mechanism of various forming processes and establish the optimization parameters suitable for the forming process to improve product quality and production efficiency and reduce production costs.
