Section 2: Pre-installation:
Before getting started, double check that the Multicyl meets the following two criteria:
- Does the Multicyl fulfill the tonnage requirements of the tool/application?
- shear length x material thickness x tensile strength = force (for shaped holes)
- PI x diameter x material thickness x tensile strength = force (for round holes)
- shear length x thickness x 3500 = stripping force (approx)
- Mutlicyls are rated at 120 PSI, the force output adjusts proportionately with the incoming air pressure level
- Does the Multicyl fulfill the stroke requirements of the tool/application?
- the advance portion of the stroke (overall stroke - power stroke) must be long enough to position the tool in place
- the power stroke must be long enough to do the work
In order to account for application variables (air pressure, material conditions, punch sharpness, tool and/or frame deflection, etc.), and to ensure a longer machine life (no machine should consistently run at 100% output),a safety margin of 25% should be applied to both stroke and tonnage requirement calculations.
Section 3: Set-up:
1) - Locate the tooling in the appropriate position inside the cage and screw the Multicyl into the threads of the mounting plate. Note that punch position within the punch assembly should be noted in case its height involves extra punch movement which would require additional Multicyl Power stroke. It is usually necessary to have the tool height recessed within the guide in order to strip the stock from the punch, however, this height should be minimized for power stroke reasons.
2) - Position the ram cap of the Multicyl above the punch or tool threading the cylinder down until there is just enough feed clearance for the part. The patented self-adjusting stroke of the Multicyl will eliminate any excess advance stroke length. Use the locking ring supplied with the Multicyl to secure the cylinder in the desired position.
3) - Make sure all caps and plugs are removed from the air cylinder head and divider plate. Connect the air control package according to the appropriate diagram.
4) - Cycle the self bleeding Multicyl a few times to evacuate air from the hydraulic system, then test with a work piece.
Note: this procedure is for standard hole punching applications only;
MultiLoc and other special applications will have a special set of set-up instructions supplied with the machine.
Section 4: General User Notes:
- Inlet air pressure must be between 40 and 120 PSI. The cylinders are rated at 120 PSI. The tonnage output is directly proportional to the incoming air pressure, ie. if the incoming air pressure is lowered by 20%, the force the cylinder exerts will also go down by 20%. NOTE: It is dangerous to operate a Multicyl above 120PSI.
- When using Multicyl, as with any air/hydraulic cylinder, it is important to keep the incoming air free from contamination. It is important to use a filter, regulator, lubricator unit to ensure a supply of clean lubricated air. Without the use of a properly installed filter, regulator, lubricator within 10 feet from the Multicyl cylinder, all warranties are void.
- When considering air consumption for a Multicyl system it is important to remember that some compressors are designed to produce full air pressure for only 50% of their running time.
Section 5: Cages (Machine Frames)
- Cages must be designed to withstand the forces and bending moments produced during operation. Remember every action produces an equal and opposite reaction. Failure to account for these reactions to punching forces in the machine design may cause application problems including loss of valuable working stroke and tool and/or cylinder damage. Standard or custom C-frames and Multicages which have been properly engineered and tested are available for all types of applications from Multicyl.
