Flying Shears

LOCATION
The Flying is Shear placed between the Quenching Box and the Cooling Bed.

APPLICATIONS
To cut the T.M.T. Bar at a temperature of 500oC and above to the required lengths.

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 prestressed to prevent seperating 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.

Cold Shears

Cold shears  arranged in the cooling bed after the output raceway, the cooling bed cooling and arranged in groups of rolling cut. With the ruler with the machine, can be cut into the customer required length of cut length.

Cold shearing machine by the cold shear body (body, clutch, brake, flywheel, pressure device, aligning baffle, brake fan), finishing device, dry petrol station and dry oil lubrication system, thin oil self-lubricating system, pneumatic control system , Hydraulic devices, cutting edge replacement devices, motors, electronic control systems and instrumentation on the part of the machine.

Working by the motor through the belt (with shield) to drive flywheel high-speed rotation between the flywheel and high-speed shaft through the pneumatic clutch control separation and integration. When the flywheel and high-speed shaft, the high-speed shaft by two deceleration to drive the spindle rotation. The main shaft is an eccentric shaft, and its eccentric part drives the link slider to move up and down. The upper cutting edge is mounted on the slider to complete the cutting action.

 In the high-speed shaft on the opposite side with the pneumatic clutch installed pneumatic brake, when the cold shear to complete the shear action, the clutch is separated from the role of the brake to brake the spindle, the cutting edge to stop.

Crank Shears

 

The Crank Shear is placed between the Roughing train & the Intermediate train.

APPLICATIONS

  • To cut front/back end & Cobble cutting of the square at a temperature of 900 deg C and above.

ADVANTAGES

The square shaped cobble cutting is saleable material to be rolled in scrap rolling mills.

FEATURES

  • The casing is prestressed to prevent seperating of casing parting surfaces on load during the milli seconds when the cut is executed.
  • The cutter ends protrude, so as to have increased blade grinding margin
  • We provide two nos. Flywheels with mechanical clutch. The additional flywheel has to be engaged for cutting heavier section. The flywheel inertia augments the power available for cutting from constant torque motor.
  • The casing front face is water cooled to avoid distortion with heating from moving rolled stock.
  • The gears are case carburised hardened & ground designed for minimum back lash. Again the gears and knife holders are designed for required intertia.

Quenching Boxes

We are engaged in offering supreme quality Quenching BoxesTMT Box that is widely installed in rolling mills and metal industry. The system is initially set by fitting the opening of the nozzles and position of the motorized valve. Our offered TMT system is of multiple injector type. Our company develops high grade quenching boxes that clean the surface through the process of scrubbing. The process begins by positioning the motorized valve and fitting the opening of the nozzles. The quenching box allows the multiple entry of fresh water at regular time duration that saves the time of quenching process. We have incorporated high grade TMT system with the bar. Our quenching box has consistency of tensile strength, ability to cut bars accurately.

Twin Channel

The twin channel offers solution to bar handling at cooling bed at high speeds. Twin channels are available for bar sizes up to 40mm in India and stock speeds as high as 30meters per second. This carries the bar in a closed channel until the material comes to a standstill position and discharges it to the bed below automatically.

This is an excellent system as it carries the bar in a closed channel, minimizing the accident hazards. Specifically while carrying out high speed rolling the system is an absolute necessity.

Cold Rolling Mills

Cold rolling occurs with the metal below its recrystallization temperature (usually at room temperature), which increases the strength via strain hardening up to 20%. It also improves the surface finish and holds tighter tolerances. Commonly cold-rolled products include sheets, strips, bars, and rods; these products are usually smaller than the same products that are hot rolled.

COLD ROLLING MILLS PARTS

Because of the smaller size of the workpieces and their greater strength, as compared to hot rolled stock, four-high or cluster
mills are used. Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass
