20-150T Manual/electric hydraulic press/Frame type gantry forging press/Molding machine

ü THE MAIN CHARACTER

The machine's main engine has combined fully advantage in all oversea and domestic machines of the same catalog.The full machine is under finite element optimization design and industrial design and has reached the result in good overall performance and practical,durable,high rigidity and high reliability.At the same time,we have optimized the machine structure and popular design.

The machine has independent actuating unit,electrical system,The relay control is applied,can be adjusted and semi automatic mode of operation.The working pressured, Slide block stroke range are adjustable according to the produce requirement.Two function Constant pressure and constant-distance forming can be reached.After constant pressure and forming,thre will be automatic return action With pressure and time delay.

ü MAIN STRUCTURE

The machine is composed by two parts:Main Machine and Control Structure,and connected by pipeline and elecric device.The main machine has composition of machine body,main cylinder and stroke limit device.Control Structure include hydraulic power unit(dynamical system) and electronical cabinet.The main division and functin is discripped as below:

n MACHINE BODY

The machine body is composed by foundation,top rail,slider block,working table,lower cylinder,upright column,locknut and adjusting nut.The precision is adjusted by adjusting nut and the locknut fixed on the top rail.Foundation,top rail,slider block are made in steel wileded structure.The plate's material is Q235-A steel,wilding adopt CO2 protective welding,heat-treatment will be in procedure after welding to eliminate internal stress.

The outside of the machine main structure will be in good smooth,no obvious unevenness phenomenon ,welding seam formation ,welding slag and shed scar imagination.Compressor structure adopt optimization design by computer,It has good strength and stiffness. "

n MAIN CYLINDER

The main cylinder is fixed to the top rail area by cylinder port shoulder and the big locknut.Lower end of the piston is connected by coupling flange,bolt and slider.The material of piston head is iron casting to act as guidance.The piston head has the imported YX type sealing ring in the opposite direction.The piston rod is provided with the O type sealing washer  to divided the cylinder into to two cylinder with guidance sleeve,The guide sleeve excircle is provided O type sealing washer with the help of the flange and bolt locking to guarantee no any leakage and highly sel in cylinder.Cylinder flange is provided with a dust ring to ensure that the piston rod of the dust .
