We are renowned as one of the most reliable Under Crank Power Shearing Machine Manufacturers in India. The Under Crank Shearing Machine offered by us is well-suited for cutting to size general purpose unalloyed steel, Structural steel sheets up to 4 mm thickness. Each machine designed to the most accurate of efficiency offers outstanding operational performance dimensional accuracy telling on high output and dependability. The Mechanical under Crank Shearing Machine is available in sizes ranging from 1270 x 2 mm to 3125 x 4 mm
Frame Constructin
All RAJESH Brand Guillotine shears fabricated from is- 226 Grade. Rolled steel plates Table and cutting Beam are deeply reinforced and fines machined after stress relieving the interlocker design put the direct support to frame thus frame is strain free and eliminate welds at load supports thus the accuracy of the machine is never disturbed.
Bed
Super strong bed of closed box type construction stress relieved in a furnace rigid backbone for the lower knife Dovetail slots in front of the bed are provides for font gauge slots on top of bed are also provided for machined pad across the bed for convenient setting of front gauge brackets at any desired spacing Depressions in the top of the bed provide ample clearance for fingers in handing sheets narrower than the bed.
OPER Beam
Ram is also of solid steel plate carrying the upper knife its minimum weight ensure lesser load on the bearings the upper beam moves in fiat heat treated steel guide plates to avoid deflection for smooth running and maintain the accurate straightness of the upper knife.
Hold – Down Machanism
Solid clamping by powerful spring Loaded hold down is one of reasons for accuracy in over shears heavy uniform pressure is applied along the full length of the work piece preventing slippage regardless of variations in thickness hold down pressure is easily adjustable for clamping soft material Different thickness of material can be cut without further adjustment with consistently accurate and burr free results.
Rolling Key Clutch
Made of alloy steel for positive engagement and continuous operation having three key ways single rolling key system is incorporated in the machine ensuring easy and efficient working of the machine.
Shear Knives
Knives are manufactured strictly as per standard material of HCHCr/OHNS. Every step from designing metallurgical specifications heat treatment grinding and inspection is carefully controlled the blades are standardized and are easily replaced.
Accurate Gauging
The rigid and accurate construction of the back gauge provides with the machine allows consistency in the width of sheets being cut.
Lubrication
single shot lubricator provides oil to all lubrications points where necessary thus all Bearing parts and Guide surface etc.
Drivel
Drive is through v- belts on flywheel and a reduction gear are made of steel hob cut for smooth running and Longer Life.
