Over Crank Shearing Machine

We are listed at the apex in the list of the well-reputed Mechanical Over Crank Shearing Machine Exporters from India. The Over Crank Shearing Machine offered by us is available in varied sizes ranging from 1270 x 6 mm to 3125 x13. The Mechanical Over Crank Shearing Machine is ideally designed for cutting to size general purpose unalloyed steel and Structural steel sheets with high productivity. Each machine, Designed to the most accurate of efficiency, offers outstanding operational performance dimensional accuracy telling on high output and dependability.

Frame Construction
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 interlocked design put the direct support to frame.

Thus frame is strain freehand eliminates 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, forms a rigid backbone for the shear and a solid backing for the lower Knife. Dovetail slots in front of the bed are provided for front 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 handling sheets narrower then the bed.

Upper 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 flat heat treated steel guide plates to avoid deflection, for smooth running and maintain the accurate straightness of the upper Knife.

Hold-Down Mechanism
Solid clamping by powerful spring Loaded hold down is one of reasons for accuracy in our 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.

Mechanical Back Gauge
Back gauge provided with an arrangement to set its connectivity, it is driven by with spocket and chain arrangement fitted on a screw set. Both the screws are made out of alloy steel material and precision machined with squared thread of the back gauge.

Lubrication
Single shot lubricator provides oil to all the lubrication points, where necessary. Thus, all Bearing parts and Guide surface etc.

Drive
Drive is through V-bents on flywheel and a reduction gear box. Gears are made of steel and hob cut for the smooth running and Longer Life.
