Rajesh Metal Sheet Cutting Machine

Frame Construction: Hydraulic Shearing Machine fabricated from IS-2062 graded rolled steel plates table and cutting beam are deeply reinforced and fines machines after stress reliving. The interlocked design put the direct support to frame. This frame is strain free and eliminates welds at load supports. Thus the accuracy of the machine is never disturbed.

Table: Super strong table of closed box type construction. Stress relived in a furnace. Forms a rigid backbone for the shear and a solid backing for the lower knife.

Upper Beam: Upper beam is also of solid steel plate, carrying the upper knife. Its minimum weight ensures lesser load on the roller. 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.

Rake Angle (Cutting Angle) Adjustment: Cutting angle of the blade is electro hydraulically adjusted with push buttons with indicator lights on the operator console. The cutting angle adjustment helps to achieve, cutting variety of material thicknesses without twist distortion.

Hold-Down: Solid clamping by powerful hydraulic loaded 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 variations in thickness. Hold-down pressure is easily adjustable for clamping soft material. Different thickness of the material can be cut without further adjustment with consistently accurate and burr free results.

Blade (Knife): Knifes are manufactured strictly as per standard HCHCr/OHNS. Every step from designing metallurgical specification, heat-treatment grinding and inspection is carefully controlled. The blades are standardized and are easily replaced.

Blade Clearance (Blade Gap): The shears are equipped with leavers calibrated in thickness on both sides of the machine to adjust the clearance between top and bottom blade according the sheet thickness. The setting can be done shiftily and quickly without use of filler gauges involving cumbersome procedure and difficulty. The use of correct blade gap ensures burr-free cutting results and improves blade life considerably.

Cylinder: The cylinder bodies are precisely made from forged steel material duly bored and fine honed for long sealing life. The piston rods are made From EN  8 material having low carbon contents. The piston rod is hard chrome platted (0.200 micron).

Hydraulic System: The compact Blocks eliminate the leakage chances and also reduces the hydraulic pipes. This low Noise hydraulic system is placed on the rear side of machine, on top between two side plates. Pressure relief value is provided to safe guard the system and Machine from overload. The hydraulic system is driven by an electric motor of reputed brand and is coupled with a pump capable of generating more than the required pressure. Pressure gauge for system pressure, backpressure and holding pressure are providing on top of oil tank for quick reference.
