[0002] A hydraulic press is a mechanical device that uses the high-pressure principle of liquid to achieve force transmission and power transmission. After the liquid is pressurized through the hydraulic system, it is transmitted and controlled in the system through the principle of fluid mechanics, thereby generating high pressure or high torque to achieve workpiece forming, pressing, shearing, bending, stamping and other process operations. Because the hydraulic press is highly dangerous and has high hidden dangers when working, a safety interlock is required to ensure that the equipment is safely controlled during operation. It detects the status of the equipment or environmental conditions and automatically performs preventive measures under specific conditions to avoid potential dangers or accidents. When the hydraulic press needs manual assistance to complete processing and overhaul the hydraulic press intermittently, a hydraulic press safety interlock support structure is required to complete the selective use of the safety interlock and support protection to solve safety hazards.
