Hydraulic press is a kind of hydraulic press. It circulates hydraulic oil in the oil tank through the one-way valve to make the oil cylinder / piston cycle work, so as to complete a certain mechanical action as a kind of machinery for productivity. Many users ask, is there any relevant protective device in its design and use?  
The hydraulic press shall be equipped with safety protection devices, and the specific types of protection devices are:  
Safety starting device: when the operator's limbs enter the dangerous area, the clutch in the hydraulic press will not close or the sliding block cannot be lowered. The hydraulic press can carry out these actions only after the operator completely exits the dangerous area.  
Mechanical protection device: when the sliding block of the oil press goes down, separate the dangerous area from the operator's hand to ensure safe production.  
Automatic protection device: light beam, air flow and electric field are set around the dangerous area of the die. Once the operator's limbs enter the dangerous area, the hydraulic press will automatically stop working through the control of radio, electricity and gas to protect the safety of the operator.
