FRAME CONSTRUCTION
Mechanical Under Crank Shearing machine Frame fabricated from IS-2062 graded. Rolled steel plates. Table and cutting beam are deeply reinforced and fines machine after stress reliving. The interlocked design put the direct support to frame. Thus frames are strain free and eliminate welds at load support. Thus the accuracy of the machine is never disturbed.
BED
Super strong bed of closed box type construction, Street 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 area also provided for machined pas across the bed for convenient setting of front gauge brackets any desired spacing. Depressions in the top at the bed provide ample clearance for fingers in handling sheets narrower than the bed.
UPPER BEAM
Ram is also of solid steel plates, 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 plates to avoid deflection, for smooth running and maintain the accurate straightness of the upper knife.
HOLD-DOWN MECHANISM
Solid clamping by powerful spring loads hold down is one of the reasons for accuracy in our shears. Heavy uniform pressure is applied along the full length of the work piece, preventing slippage regardless of versions in thickness. Hold down pressure in easily adjustable for clamping soft material. Different thickness of material can be cut without future 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 standards are standardized and are easily replaced.
ACCURATE GAUGING
The Rigid and accurate construction of the back gauge provided with the machine allows consistency in the width of sheets being cut.
LUBRICATION
Single shot lubricator provides oil to all the lubrication points, when necessary. Thus, all bearing parts and guide surface etc.
DRIVE
Drive through V-belts on flywheel and reduction gears are made of steel, hob cut for the smooth running and longer life.
