 What
is a Multicyl®?
Multicyl® is a patented air over oil press used for punching applications. Its
original design was for punching holes and notching in sheet metal but now the
uses include everything from automated manufacturing to a simple workstation.
Customers include almost anyone who has a product to make, from IBM or
General Motors to the inventive individual working on their first project.
Its small size and portable feature is good for either bench mounted or movable
applications.
Quiet, safe and affordable... Applications are limited only by the
imagination of the user.
How
Multicyl® Works.
Discover the Simplicity of Multicyl®. A Multicyl® is quite complicated
internally, however like a car engine, to the user it's easy to operate. Stroke
and tonnage specifications are all that's required for cylinder selection.
Design time is reduced by using our standard package components for cage,
tooling and air controls. Installation time is reduced with the self-contained
reservoir, which is self-bleeding. No hydraulics or electrics to worry about...
All you add is Air.
Multicyl® is fast-acting and efficient. Ton for ton Multicyl® is
probably the world's most cost effective power source. Multicyl® delivers a
tested 60 strokes per minute and up to 100 TONS punching power at 100 psi
shop air. Significantly more efficient than more traditional methods. A smaller
compressor can be used because of low energy requirements. Multicyl® delivers
its dynamic punching action only when needed, unlike a die Punch Press which is
always running.
Multicyl® simplifies the field of air/oil intensifiers while saving up to
80% of the compressed air used in other air operated systems performing a
similar function, such as air cylinders or Single Stage pressure intensifiers.
The Two Stage pressure intensifier produces its power action utilizing regular
shop air and the most elementary control valve... this is all that is
required.
The compact design incorporates the hydraulic functions completely within the
one, integral unit, eliminating the need for and external oil reservoir or
complicated control circuit.
Low Pressure (LP) stroke (Advance Stroke) : As air is introduced,
pressure is supplied to the system. As LP piston advances, LP valve immediately
closes and the ram continues to advance in a full linear fashion until
resistance is encountered. The LP stroke is dissipated by the hydraulic flow by
principle, permitting the air cylinder to continue its advance while the ram
remains stationary until the High Pressure is attained. The length of this
stroke will automatically self-adjust and allow the power stroke to actuate
wherever the advance force is exceeded. The Air Advance Stroke will produce a
force equal to the pressure on the air piston (less the resistance of internal
springs and seals).
High Pressure (HP) stroke (Power Stroke): HP piston rod seals the
high-pressure chamber. The increased diameter of the HP chamber renders the LP
piston powerless. This allows the oil to flow freely within the HP chamber as
the LP piston advances. The force on the ram is increased due to the pressure
being multiplied by the ratio between the areas of the air piston and the HP
piston rod and the area of the ram piston. On the return stroke, air is
exhausted; LP valve immediately opens... allowing oil to flow directly through
the piston; springs return LP piston assembly and ran to "rest position". The
hydraulic power stroke may be produced anywhere on the overall stroke. The
changeover signal is produced from resistance greater than the advance force.
The stroke length will bottom out at the end of the power stroke or wherever it
is exceeded.
The "Flow-By" Principle (Self-Adjusting Stroke): If the ram stops due to
resistance before the high pressure piston has reached the main body seals, the
patented Multicyl® "flow-by" principle comes into effect. The piston is allowed
to continue its advance as entrapped oil begins to "flow-by" the low pressure
piston by means of precisely controlled clearances. When the HP stage is reached
the LP piston becomes ineffective due to an increase in bore diameter of the
cylinder.
Multicyl® reduces the need for the fine adjustment by producing its working
stroke where the low pressure force is exceeded-anywhere on the overall stroke.
Its "Jam-Proof" action will bottom-out at the end of the working stoke or
wherever the high pressure force is exceeded.

Why use a Multicyl® for your Punching Application?
1) Lower cost. Initial capital outlay is less than conventional
equipment such as punch presses or hydraulic punching machines. A single station
is probably the most cost effective alternative for tube piercing.
2) Flexibility. Buy now and add more units for tomorrow's
needs.
3) Safety. Small workstation, only one moving part... simple to
safeguard
(for more information please refer to the
Safety Section).
4) Quick Set-Up. For fast piece part set-ups simply add or
delete a tool station.
5) Small compact size. Piece holes as close together with
standard cages. Ask for special tooling quotes from Multicyl.
6) Portability. Connect a mobile work station wherever shop air
is available. Move the machine to the job if the parts are to big to move.
Relocate from one tool fixture to another in seconds.
7) Simplicity itself. Easy to set up, operate and maintain.
Only one visible working part (the punching ram). Uses standard air controls and
shop air, not a costly, elaborate arrangement of hydraulic valves, manifolds and
gauges.
8) No Hydraulics. Cost-effective pneumatic systems allow design
flexibility. No formulas to calculate for oil volume, displacement, hose
expansion or line capacity. Multicyl and cage is simply mounted to a steel base
plate or other suitable mounting surface and moved to any location where air is
available. Periodic replenishing of oil supply and replacement of seals is about
the only maintenance required.
9) Building Block System. Buy for today's needs then add more
system components as required. When increased tonnage is required the
appropriate number of Multicyls may be used to supply the right force for the
job. Caution should be taken to incorporate a balanced load condition within the
tool. Air cylinders may be used in place of return springs in order to raise the
top bolster, which should be strong enough to withstand distortion under full
load.
Key points to keep in mind.
Multicyl® is a unique tool geared for today's needs : efficient
economical hole punching for short, medium or high production runs.
Multicyl® beats all comparable systems (air & hydraulic) in simplicity,
ease of use, efficiency & savings.
Fast, easy changeover keeps downtime to a minimum.
Virtually limitless application... almost anyone who punches holes could
use it.
Pre-engineered for consistently superior punching power.
Safe and simple enough for operation by less experienced personnel.
A proven energy saver... uses no energy when not actually in operation.
Quickly pays for itself... in labour, downtime and space saved.
A single source for all Multicyl® needs... we provide it all :
components, and a full range of accessories.
Air consumption can be up to 10 times less than an air cylinder
performing a similar task.
Air Controls. A simple 3-way valve will actuate this single acting
cylinder. A quick exhaust is mandatory. The Filter/Regulator/Lubricator should
be adjusted to allow for one drip of oil every 30 cycles. |
