Characteristics of the hydraulic press / press machine / power press :   Y27Y series hydraulic fast press is suitable for punching,stretching and pressing of plasticmaterials,such as punching,bending,flanging of plate, stretching and fine punching of sheet metal,and cold extrusion of metal part.It may also be used for cailbration,press-in,forming of grinding wheel,press forming of plastic products and powder products.   The machine uses hydraulic driving mode and has the advantanges of a hydraulic press and a machanical press.Pressing force of the machine can be changed at will. Overload will not occur in the machine.It can realize pressure keeping and time delay requirements in during pressing.In orderto realize slippers quick moving downwards without load and quick back stroke,the machine uses speeding-up oil cylinders.The machine began to operate automatically at a slow speed as it contractsa workpiece,which decreases discharge capacity of an oil pump and motor power,and reduces noise.Photoelectric protection devices may be installed in front of a bench,which forms a protection screen on upper front of the bench so as to protect operators.It uses centralized buttons,which mayrealize adjustment,semi-automatic and automatic operations.Therefore,the machine has the advantagesof novel structure,reliable performance,a complete range of functions and high production efficencyof,and it is a substituting product of a mechanical press.
