machining workpiece with different heighs does not pose a problem,power stroke only built up when meet counterforce

hydro pneumatic presses

Hydro pneumatic press combines the advantages of hydraulics and pneumatics technology into one machine,with compressed air as power source and has hydraulic force,output force is from 1 ton to 100 tons.its fast approach stroke to contact workpiece with a low force and then builds up full power to mould product.as its fast approach stroke is compressed air operated,so its speed is faster and energy-saving unlike hydraulic system to reduce production cost.Machining workpiece with different height does not pose a problem,as the power stroke is only generated when a corresponding counterforce is met at any position throughout the overall stroke.it is controlled and works in the same way as a double-acting pneumatic press.The newly patented Hydro Pneumatic Press is an alternative to high-volume pneumatic systems,pure hydraulic systems and mechanical actuators.Various sizes are available for different power ranges and stroke lengths.

Characters:

With compressed air as power source, easy to operateThere is no noise and electricity consumption unlike the hydraulic system generated in standby to reduce production costs.With the advantages of hydro pneumatic technology,works faster with high pressing force.It is easy to adjust machine’s pressing force,only by regulating pressure of air source,you can get your required force.solid structure,easy to operate,convenient to upload and download materials,that ensure efficient work.Multifunctional use for indentation, punching, riveting, assembly, cutting, etcSafe and humanness design,comfortable operation,suitable for long-term operation.Four-columns door-open-space design and customized machine is acceptableDifferent size working bed is customized,normally, 650*550*700mm

Operating manual:

To start machine by two hand buttons,time relay controls machine’s return stroke.Connected to power,in the “manual” state,operator can make machine do low force inching rise or inching drop action by pressing inching rise or inching drop buttons,so as to correct moulds.In the “automatic” state,machine will start after operator put workpiece on work bed and press switches by two hands.during fast approach stroke,the upper moulds move to workpiece quickly and gently with low-noise,no impact,when upper moulds contact with workpiece machine will build up full power(power stroke) automatically from fast low force approach stroke until set-up time over,then time relay controls moulds returning automatically,so as to insure machine builds up enough pressing force required.Speed of Fast approach stroke and returning stroke can be adjusted stepless,so as to meet different working frequency requirement.Machine’s maintenance system can process inlet compressed air so as to make it gas-water seperated and oil atomization,you can also adjust the pressure of inlet air source stepless,so that machine’s output force is adjustable stepless.With an emergency returning button,moulds can return immediately anytime.There is a power stroke regulating valve,which can adjust pressing force of power stroke while machine’s speed is not changed,in this way it can protect moulds and energy-saving.
