Shears & Shaw

Our Billet Shearing Machine Possess the following Technical Specifications and Features:

• Machines are made to cut different sizes of billets, blooms, and slabs
• Prime MS Plate for body fabrications
• A weight control system of cut blanks
• Cutting capacity – 50 mm to 300 mm
• Gears train will be provided to facilitate operations with small power
• The specialized machine is used for cutting of stainless steel billet – 50 mm to 200 mm
• Body is fabricated from mild steel

Our Cold Shearing Machine Possess the following Technical Specifications and Features:

• Manual and Automatic operation
• The tailor-made suit as per customer requirement
• Compact Design, Easy operatable, Easy Maintenance and Low power consumption
• Cutting capacity 8 mm to 32 mm TMT bars, 8 mm to 100 mm rounds/squares, plates, angles, channels & girders
• Capacity 1 Ton to 20 Ton per Hour
• Strokes per minute – 6 to 35 strokes

Technical and Design specification of the Continuous Rotating Shear:

• 8mm to 16mm TMT bar. Single Shear is sufficient for ingot rolling mills.
• The first cut of this shear is not accurate, but the subsequent cuts are very accurate. The material loss of first cut is compensated by the subsequent cuts.
• The motor power is only 50 KW, compared to 90, 130, 175 KW of Start Stop Flying Shear.
• The casing is vertically split to take the separating force during the the milli seconds when the cut is executed on the casing profiles instead of parting bolts.
• The blade holder is fitted with double cone torque couplings as a safeguard against the accidental overload.
• The Flywheels are provided to reduce the motor power. The flywheel intertia augments the cyclic cutting load.
• The gears are case carburised hardened & ground designed for minimum back lash.
• Shifter present for moving bars in path of blade
• Presence of servo motor for shifting line of rolling
• Shifter mechanism at shear exit where shifting is performed through pneumatic mechanism
• Main shear body with cover provided for safety of men & machinery

Features :

• Used in form of pairs between roughing as well as intermediate finishing stands for cropping front & back ends in TMT Bars/Wire Rods
• Extensively finding application in cropping front, tail and also scrapping pre quenched bars at times of emergency
• Shears specifically designed for trimming of hot rolled bars at lower speeds
• Precision engineered frame fabricated using stress relived structural sheet flats
• Drive Gear Box developed using quality steel plate body and backed by superior oil lubrication support
• Shearing blades of superior grade steel
• Precision engineered forged shafts coming mounted to roller bearings with gear box connected through V-Belt and pulley
• Pneumatic cylinder for controlling shearing as well as swiveling operations of shears blades
• Dual rotary helical cutting blades that deliver excellent cut quality

Features :

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.

Our Hot Saw Possess the following Features:

• Rolled section is gripped on the run out roller table
• Cuts heavier section with better straightness
• Heat resistant, Superior durability, Precise & sharp tooth and Corrosion free
• Easily cuts beam, channel and angle
• Increases the productivity of extrusion system
• Cuts every billet to the uniform size
• Removes trim front end
