Project Background
The pressure timer panel is a key component for maintaining the process precision of a cold press. It controls the timed auto-repressure function: by presetting the relief time and timing cycle, the press self-regulates its pressure during continuous pressing, ensuring stable workpiece forming. The panel is integrated into the electrical control box; all parameters are factory-configured and ready to use, with custom adjustments possible when needed. Check the parameter status and wiring quarterly.
Solution
Two core parameters: ① Relief time — the duration of the momentary pressure release, e.g. 0.5 seconds. It briefly releases pressure to avoid material stress concentration and works with the pressure gauge for precise repressurization. ② Timing cycle — the interval between two repressurization operations, e.g. 60 minutes, with progress displayed live on the control screen. The two must be set in coordination, forming a complete repressure logic chain.
Results
Example workflow (with the illustrated parameters): Timer starts — once pressing begins, the on-screen timer counts up to 60 minutes. Relief triggers — at 60 minutes, the system automatically performs a 0.5-second momentary pressure release. Pressure recovers — after relief, the pressure gauge monitors the value in real time and triggers the hydraulic system to re-pressurize to the set pressure. Cycle repeats — the timer resets and the next cycle begins.
Customer Feedback
"Operation notes: parameter changes must be performed by professional technicians to avoid affecting equipment stability; run a no-load test after adjustment to confirm the action logic; the repressure function relies on pressure gauge feedback, so calibrate regularly to ensure accuracy."
