DEscriptION :

N-SERIES PRESS :

N-series range of Hydro-Pneumatic Presses, combines the advantages of efficient, low cost pneumatics, to achieve the large output forces associated with hydraulics. The system operates on normal compressed air pressure of 5 bar,
using standard pneumatic controls, thus completely eliminating the use of expensive hydraulic power pack and associated control equipment.

The system consists of a hydraulic cylinder, an air to oil intensifier and an oil reservoir, all combined into a compact integral unit. The output ram approaches the work piece at rapid speed (which can be adjusted) under low
pressure (hence low force) compressed air. On touching the work piece (at any point along the travel) the intensifier is automatically energized by means of a suitable directional control valve. This results in a high pressure (hence high
force) stroke up to a maximum of 24 mm. The ram retracts rapidly at low pressure on completion of the work cycle.

FEATURES :

Very low air consumption, resulting in energy saving of up to 80% over equivalent pneumatic cylinders and 50 % over equivalent hydraulic systems

The Speed of Operation is also much higher than an equivalent standard pneumatic or hydraulic system.

Compact Cylinder design, which can be mounted in any position.

Compact, Lightweight Press frames, which can be mounted on a light work table.

Simple Design for easy maintenance.

High stroke frequency because of shorter oil path between the oil reservoir and the output hydraulic cylinder.

Force and Speed can be infinitely adjusted.

Rapid pneumatically operated approach stroke and return stroke. In the "N" Series the return force is larger than the approach force, resulting in the loading of heavier tools for respective tonnages.

Absolute separation of air and oil chambers. This has been achieved by providing bleed holes between the pneumatic and hydraulic seals. In the event of failure of pneumatic seals, the air escapes to atmosphere through a bleed hole
and does not mix with the hydraulic oil. If the hydraulic seals fail, oil escapes from its bleed hole, indicating deterioration of the seal, which can be procured and replaced well before total breakdown occurs.

ADVANTAGES :

Uses Compressed air as the power source resulting in reliable, inexpensive components and piping. Completely eliminates the use of expensive hydraulic components and a large oil tank to be filled with a large quantity of expensive
hydraulic oil.

Fast response because of the use of compressed air for rapid approach and retraction.

Compact and light weight. Can be mounted on a table top. Further there is a saving in floor space occupied by a hydraulic power pack of a hydraulic system.

Saves up to 50 % in energy input over fully pneumatic and hydraulic systems and 70 % in cost compared to hydraulic systems.

Easy to maintain because of simple pneumatic elements and sealing components.

APPLICATIONS :

Mercury low cost “ hydro-pneumatic presses are an ideal replacement for expensive hydraulic presses for varied applications such as riveting, Forming, Clamping, Bending, Straightening, Marking, Punching etc. Lowinvestment,
Energy saving, negligible maintenance, fast action and infinite control over force and speed are the major advantages over equivalent hydraulic systems.

operations in bearing industries, Automobile industries, Gas lighter and kitchen
ware appliances manufacturing plants, Electrical switches , Switch gears, Rubber
parts, Shaft straightening applications, Bush Pressing applications and many
more

Operator's Safety :

The press is operated by means of micro-processor based control card in electrical panel to take care of operator's safety during the operation. This is called as True, Non Tie down, Interlocked Two hand safety operation.

Auto-cycling & Parking Features:

The Press can be operated to have total 9 Nos of power stroke in sequence with auto cycling feature in electrical control panel there by removing the limitation of limited travel of power stroke. Also our parking feature will help
you to increase the operating frequency by limiting the reversal travel of ram up to available power stroke through parking system which is available as an option.

Auto-Lube System:

Our new Auto Lubrication feature has greatly enhanced the reliability of our presses. After a set ( with jumper on PCB) number of cycles, the auto lube solenoid comes on for a short time. This actuates a built-in pump which injects
under high pressure, about 8 drops of oil from the reservoir. This high pressure injection ensures complete lubrication of the entire pneumatic components. The advantage of this system is that lubrication is positive and not dependent on
air flow volume as in a standard lubricator of a FRL set. Also the quantity of lubrication is positive and not dependent on any arbitrary setting by machine operator.
