"Modern Machine Tools" pedal operated rocker arm type spot welding machine are offered in 6, 8, 10, 15, 20 and 25 KVA models each with three standard throat depths to cover practically all applications. All machines are made of steel fabricated rigid structures to eliminate the minutest spot deflections TRANSFORMER: Low leakage (High Linkage) design, proper cooling and insulation including winding impregnation to enhance reliability and service life. CURRENT CONTROL Current seting from min, to max. value can be done by a 6 position, off loap tap switch. TIME CONTROL Solid state Electronic timer to control weld time from 5 to 50 cycles and 1 to 10 seconds to achieve accurate and repeatable spots. WELD PRESSURE Adjustable max. pressure levels are derived from a heavy-duty comression spring mounted on a pressure rod with caliberated nut. Here a special arrangement in the machine minimises operator fatigue and ensures simple seting. COOLING Electrodes, holders and arms are provided with water cooling arrangement with hose connections. (Water supply to be attanged by the user.) ELECTRODES One Pair of Morse Taper 2 straight electrodes made from hardened copper-alloy is supplied with the equipment. Other types or spare electrodes can be supplied on specific orders.
Press Brake Machines are designed taking in to consideration all severe service conditions of sheet metal shop. The machine are heavy duty robust in design and acclaimed recognition in requiring high accuracy productivity & efficiency. Frame Construction: Frame in made of steel fabricated construction of interlocked robust design. Machines are constructed with safeguards against undesired deflections and breakage. The frame distributes the stresses, supporting the bed directly on the frame. The double support shoe of frame gap provides extremely high rigidity, alignment, accuracy and keeps frame structure at right angles to the bed. Ram & Bed: Ram and bed are straight and parallel of both the working surface under the rated load. The bed is accurately machined and upper surface is grinded to keep the die in correct alignment. The ram is guided and supported throughout the stroke by accurately machined guide ways. Lubrication System: The lubrication system on a machine is an assurance for its trouble free running. The bearing parts are linked with high density polythene pipe – line spread at every point where lubrication is required. Clutch and Brake: Press brake are provided with high-torque low-inertia friction clutch, synchronized with heavy duty. The powerful disc type clutch is easily accessible, simple to adjust and picks the load from standing start and it frequent start & stop. The brake is interlocked with clutch to stop the ram immediately at any point of motion. When the clutch is released. Clutch operating levers are designed in such a way that minimum engaging force is required at the pedal. Drive System: Power is transmitted to the ram through two individual gear drives for uniform load distribution throughout the length. This also reduces the torsion stresses on the eccentric shaft. Electric motor used is of sufficient H.P. which reduces slowdown of flywheel and increases energy available per stroke. The gear and pinion are made out of carbon steel. Ram Adjustment Mechanism: Motorized ram adjustment making it very easy to adjust the shut height to a desired value. The clutch offered easy operation in disconnecting either of Right or left screws in order to set the ram in correct position. This mechanism facilitates quick bending angle adjustment. Angular ram adjustment is made simple by incorporating a spring loaded dog clutch.
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: Guillotine shearing fabricated from Is-226 Grade. Rolled steel plates. Table 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 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 than the bed. Upper Beam: Ram is also of solid steel plate, carrying the upper Knife. Their minimum weights 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 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 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 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 specification, 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. Drive: Drive is through V-Belts on flywheel and a reduction gears are made of steel, hob cut for smooth and longer life.
