Longer mold life can be achieved by following a few basic
rules. Be sure to clean all parts and mating surfaces thoroughly before
assembly. Always be sure parts are properly aligned and use proper torque
requirements. To assure that parts are square, start with a good working
surface (Besser portable mold jig). A visual inspection is suggested to make
sure parts are not burred or scored.
NOTE: Always start with new lock washers and only use a
brass hammer.
- Outside division plates should be torqued to 625 - 675 Ft. Lbs., (850 -
915 Newton Meters). Outside division plates with cutouts for face liners
should be torqued to 600 - 650 Ft. Lbs. (810 - 880
Newton-Meters).
- Besser’s high strength vibrator bolts should be torqued to 285 - 300
Ft. Lbs., (385 - 405 Newton Meters).
- Core bars should first be snugged initially front and back.
- Then core bars should be torqued to 70 - 90 Ft. Lbs., (95 - 120 Newton
Meters). Align front and back as uniform as possible to the mold side
bars. Check cores for center between division plates to assure uniform
block dimensions. (A wire can be secured through the hold down bolt heads
as a safety to prevent the bolts from coming loose during constant
vibration.)
- Secure plungers to stripper head plate - 100 - 140 Ft. Lbs., (135 - 190
Newton Meters).
- Align the stripper shoes.
- Threaded inside division plates should be torqued to 40 - 50 Ft. Lbs.,
(55 - 65 Newton Meters). Tanged inside division plates should be torqued
to 100 - 120 Ft. Lbs., (135 - 160 Newton Meters).
- End liners should be torqued to 100 - 140 Ft. Lbs., (135 - 190 Newton
Meters). Low height end liners should be torqued to 90 – 110 Ft. Lbs.,
(125 - 150 Newton Meters).
- Stripper shoes should be torqued to 65 - 75 Ft. Lbs., (90 - 100 Newton
Meters).
- Center Posapac® Vibrator Weights as close as possible to assure uniform
vibration and that the nuts face the outside of the mold. The bolts
securing the vibrator weights must be of the same length and the nuts must
be the same weight.
SAFETY BULLETIN
This notice is issued to advise you that some previously
accepted shop practices may not be keeping up with
changing Federal and State Safety and Health Standards. Your current shop
practices may not emphasize the need for
proper precautions to insure safe operation and use of machines, tools,
automatic loaders and allied equipment
and/or warn against the use of certain solvents or other cleaning substances
that are now considered unsafe or prohibited by
law. Since many shop practices may not reflect current safety
practice and procedures, particularly with regard to the safe operation of
equipment, it is important that you
review your practices to ensure compliance with Federal and State Safety and
Health Standards.
IMPORTANT
The operation of any machine or power-operated device can
be extremely hazardous unless proper safety precautions
are strictly observed. Observe the following safety precautions:
Always be sure proper
guarding is in place for all pinch, catch, shear, crush and nip points.
Always be sure that
all personnel are clear of the equipment before starting it.
Always be sure the
equipment is properly grounded.
Always turn the main
electrical panel off and lock it out in accordance with published lockout/
tagout procedures prior to making adjustments,
repairs, and maintenance.
Always wear
appropriate protective equipment such as safety glasses, safety shoes,
hearing protection and hard hats.
Always keep chemical
and flammable material away from electrical or operating equipment.
Always maintain a
safe work area that is free from slipping and tripping hazards.
Always be sure
appropriate safety devices are used when providing maintenance and repairs
to all equipment.
Never exceed the
rated capacity of a machine or tool.
Never modify
machinery in any way without prior written approval of the Besser
Engineering Department.
Never operate
equipment unless proper maintenance has been regularly performed.
Never operate any
equipment if unusual or excessive noise or vibration occurs.
Never operate any
equipment while any part of the body is in the proximity of potentially
hazardous areas.
Never use any toxic
flammable substance as a solvent cleaner.
Never allow the
operation or repair of equipment by untrained personnel.
Never climb or stand
on equipment when it is in operation.
It is important that you review
Federal and State Safety and Health Standards on a continual basis. All
shop supervisors, maintenance personnel, machine
operators, tool operators, and any other person involved
in the setup, operation, maintenance, repair or adjustment of Besser-built
equipment should read and understand this
bulletin and Federal and State Safety and Health Standards on which this
bulletin is based. |
