4.2 Rating Points (Mechanical Power Press)
(A)STANDARD RATING POINTS SHALL BE AS SPECIFIED INTABLE2.
(B) DRIVE DESIGN SHALL BE BASED ON PROVIDING THE
TORQUE, WHICH PRODUCES THE RATED PRESS CAPACITY AT THERATING POINT(SEE FIG.2).
(C) PRESS CAPACITY AT POINTS OTHER THAN THE RATING POINTARE SHoWNIN
( 1)MANDATORY APPENDIX I FOR PRESSES RATED AT12.7 MM(V 2 IN.)
(2)MANDATORY APPENDIX II FOR PRESSES RATED AT6.3 MM(√ 4 IN.)
(3) MANDATORY APPENDIX III FOR PRESSES RATED AT 1 .6 MM ( 1 ⁄ 1 6 IN.) 4.3 Energy Capacity (Mechanical Power Press)
4.3.1 Function of the Flywheel. THE ENERGY REQUIRED FOR PERFORMING PRESS OPERATIONS IS STORED IN THE FLYWHEEL. DURING THE WORKING PORTION OF THE PRESS CYCLE, THE FLY- WHEEL SLOWS DOWN AS IT SUPPLIES THE REQUIRED ENERGY TO THE DRIVE TRAIN.
