Hydraulic presses are mechanical devices meant to exert large amounts of force. They can be operated in areas where motors may not be practical and can exert very large forces without taking up much space. However, hydraulics depend on a hydraulic fluid, which must always be present in the system. Hydraulic pressesuse hydraulic force to compress two plates.
The hydraulic system in a hydraulic press has the same sort of components as all hydraulic systems. It comprises two cylinders, one on top of the other, which can hold hydraulic fluid, and a pumping system to move the fluid. Generally, oil is used as a hydraulic fluid because it relieves the necessity of lubricating the components of the hydraulics.
1. Before starting, check parts of press manipulation, clutch and brakes are active, the security guard is complete and easy to use, whether ministries crank exception. If abnormal, should immediately take the necessary measures 2. Before formal operating subject to idle test, be sure each part can normal work. 3. The operation must use the tools, is prohibited by hand directly into his mouth extract die, hand tool should not be putted on the mold. 4. Foot must be far away from the foot pedals, when adjust or get the workpiece in mould area. 5. Sudden power off or operate finished, we should close the power, and restored to the clutch in neutral gear manipulator, brake in braking. 6. On the press for maintenance, adjustment and installation, adjustment, dismantling the mold should be disconnected the machine energy (such as electricity, gas, liquid). Putting warning notice on the startup switches.
