The 1000 mm CRS (adding to the manufactures cost because with 1000 mm centres the depth of the shear also has to be increased leading to increased dia gears, shaft lengths, casing weight) instead of 800 or 850 CRS so as to reduce the base rpm of the drives Motor. Since it is a start stop shear the motor shall have to accelerate to lower (base) rpm hereby reducing power consumption on recurring basis and generate payback.
The casing is pre-stressed to prevent separation of casing parting surfaces on load during the milli seconds when the cut is executed.
The cutter ends are involute profiled at ends. The cutters engage before the bar touches the cutting edge, eliminating possibility of erroneous blade over lap.
We provide an optional arrangement of Flywheel with mechanical clutch. The flywheel is engages for cutting above 20 mm bar size. The flywheel inertia augments the lower power available from constant torque motor running at low rpm to match thicker bar rolling speed.
The casing front end and pinch roll cantilever shaft is water cooled to avoid distortion with heating.
The gears are case carburised hardened & ground designed for minimum back lash. Again the gears and knife holders are designed for minimum intertia.
