MAINTENANCE

To ensure operator safety and maintain productivity, a regular press inspection and maintenance program should be employed. This program should maintain records of inspections; preventative maintenance and repairs for each press.  Should you have any questions, contact a Kenco Press specialist for assistance.

On a daily basis:

• Lube flywheel bearings
• Lube crankshaft main bearings
• Lube connecting rod pin bearing
• Lube both right and left ram guides
• Lube ram ball socket and trip linkage
• Inspect entire press for any possible problem area including loose safety covers
• Check drag brake adjustments
• Check the die area is clean and free of accumulated material, rags, chips or scrap
• Inspect the condition of personal protective equipment and material-handling tools

Oil fittings are installed on each main crankshaft bearing, on the outside hub of the flywheel, on top of the connecting rod, and on each ram guide.  Each oil passage has a felt oil wick to retain the oil over an eight (8) hour period.  When oiling, always allow sufficient time for all oil to saturate wick.

On a monthly basis:

• Check tension of the drive belt, readjust if necessary
• Inspect all trip linkage components for worn or misaligned parts; replace immediately any linkage parts showing signs of wear
• Inspect drag brake lining for wear; replace shoes if 1/16" lining or less is remaining

On a semi-yearly basis:

• Adjust ram guide clearance
• Check ram ball socket fit to ensure no excessive play exists
• Tighten all bolts and nuts and generally inspect press for any loose parts, cracked insulation on wires, etc.
• Remove flywheel cover and flywheel; carefully inspect all clutch components for wear

 

Brake Adjustment

A front damping brake is installed as standard equipment on all Kompac presses.

Adjust the brake so that the mark on the connecting rod is near the center of the release area (see illustration for the ideal stopping condition). If the brake is too tight, the crankshaft will stop prematurely and be partially engaged. This is also true if there is heavy drag on the ram or the die set. If the brake is adjusted too loosely, the same action will occur, but in a different manner; the crankshaft will coast completely through the backside of the cam and whiplash into partial engagement. This condition must be corrected as it will prematurely damage the clutch parts. The brake is best adjusted after the installation of any dies and tooling due to the added mass.

Roller Clutch Assembly

The roller clutch on the Kompac presses are packed in roller bearing lubricant at the factory. Unless grease seals are broken NO lubrication is required for two years (4,000 hours.).

1. To remove roller clutch from the press, remove set screws from outside thrust collar, remove outside thrust collar, retaining felt, flywheel assembly and roller clutch cage. (The roller clutch actuating spring is released by removing the roller clutch cage.)
2. Remove set screws holding the roller clutch cam and press the crankshaft through the quill towards the front.
3. Remove the quill roller bearings, race, and roller clutch parts from the flywheel assembly and the crankshaft.
4. Carefully inspect and replace any worn parts. Pay close attention to the roller clutch cam which may have an indentation in the cam at the point where rollers come in contact. If there is an indentation of .001" - .002", the cam should be replaced.
5. Pack the Quill roller bearings with #3 roller bearing grease, working the grease around the rollers within the quill bearings.
6. Replace all retaining felts after the felts have been saturated with oil. This will prevent the felts from absorbing the grease from the quill bearings.
7. Reassemble the cam onto the crankshaft; to avoid bending the crankshaft, press cam squarely and evenly.
8. The roller clutch assembly is now ready for another two years of service.

CAUTION: Prevent any oil or grease from entering the roller clutch area. Contamination will cause malfunction within the roller clutch and serious damage may be incurred.  The oiled felt wick will provide sufficient lubrication for the clutch drive rollers.
