Mechanical Under Crank Shearing Machine
Mechanical Under Crank Shearing Machine
Mechanical Under Crank Shearing Machine is suited for cutting to size general purpose unalloyed steel, structural steel sheets up to 4mm thickness, 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 guillotine shears fabricated from IS - 226 grade rolled steel plated. The 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 free eliminate welds at load supports. Thus the accuracy of the machine is never disturbed.
Bed
The 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 fro-front gauge. The 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. The depression 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
The solid clamping by powerful spring loaded hold down in one of reason for accuracy in our shears. The heavy uniform pressure is applied along the full length of work piece, preventing slippage regardless of variations in thickness. Hold down pressure is easily adjustable for clamping soft material. The different thickness of material can be cut without further adjustment with consistently accurate and burr free results.
Rolling Key Clutch
It is made of alloy steel for positive engagement and continuous operation having three keys 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 HCH Cr/O HNS. 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 provided with the machine allows consistency in the width of sheets being cut.
Lubrication
Single shot lubricator provides oil to all the lubrication points, where necessary. Thus, all bearing parts and gude surface etc.
Drive
Drive is through V - belts on flywheel and a reduction gear are made of steel, hob cut for smooth running longer life. .
