Product Details: - FRAME: To ensure rigidity and accurate alignment to the complete assembly and to, unsure against vibrations and detractions, cast iron side walls having large dimensions and cross section, properly ribbed at critical places are provided. Except for side walls and all other parts are steel fabricated. TABLE: Steel fabricated, box type table is heavily ribbed for strength and is stress relived, Its machined seat provides true and firm support to the bottom blade. It is adjustable for setting the blade clearance. The top surface of the table is provided with T slots for adjusting the front guage. UPPER BEAM: Upper beam is fabricated with thick M. S. plate. It is heavily ribbed from behind and is stress relieved. The top blade is fitted at its accurately machined seat, its sliding surface are machined and hand scrapped for smooth travel and sustained accurately.

GUIDE WAYS: Accurately machined guide ways keep the upper beam in its bearing throughout the stroke. A taper wedge is provided to compensate for the wear and to facilitate quick setting of the blade clearance. HOLD DOWN DEVICE: The spring-loaded mechanical hold down pads hold the sheet securely, to avoid slipping and bowing resulting in clean square cut, hold down units are provided with oversize pads to avoid impressions on sheet metal on request. DRIVE, CLUTCH AND BRAKE: DRIVE: Motor, mounted on an adjustable platform, drives the large cast iron fly wheel through vee belts. The power is further transmitted to the fly wheel shaft through steel pinion and main gear. Gun metal bushes are provided all the rotating parts. CLUTCH: Rolling key clutch is linked with the main gear and engages every time when the foot switch is pressed.

BRAKE: spring tensioned brake fitted at the end of the crank shaft to damp inertia. FRONT AND REAR GAUGES: FRONT GAUGE: T Slotted front gauge fabricated from mild steel is detachable. REAR GAUGE: Rack and Pinion type rear gauge provides accuracy and is easily adjustable to cut parallel and taper strips efficiently. BLADE: President shears are provided with high quality single segment (Hc, hcr) blade with four edged.

LUBRICATION: All bearing parts and guide surfaces are lubricated through connected oil cups and hand operated lubrication pump. STANDARD EQUIPMENTS: Rear gauge, Side squaring and Front gauge, Foot pedal switch, Motor pully, Gear & Fly wheel guards, Standard instruction manual and Spanner. STANDARD ACCESSORIES: Electric Motor, Starter, Vee belts, Manual lubrication pump, Front gauge, Rear gauge with scale and stroke counter, Electric and lubricating pipe fittings and wiring. POWER SUPPLY: 400 / 440 Volts, 3 Phase, 50 Cycles. NOTE: Electrical items & blade are not under warranty.

product details: - frame:the machine is fabricated with thick prime m. s. plates. its inter-locked and massive construction imparts maximum strength to the assembly.
table:steel fabricated, box type table is heavily ribbed for strength, and is stress, relieved. its machine seat provides true and firm support to the bottom blade. it is adjustable for setting the blade clearance. the top surface of the table is provided with t slots for adjusting the front gauge.
upper beam:is fabricated with thick m. s. plate. it is heavily ribbed from behind and is stress relieved. the top blade is fitted at its accurately machined seat, its sliding surface are machined and hand scrapped for smooth travel and sustained accuracy and heavy-duty springs are provided to counter balance to upper beam.

guide ways:accurately machined guide ways keep the upper beam in its bearing throughout the stroke, a taper wedge is provided to compensate for the wear and to facilitate quick setting of the blade clearance. hold down device:the hold down is actuated by cam on the crank shaft through levers. the spring-loaded mechanical hold down pads hold the sheet securely, to avoid slipping and bowing resulting in clean, square cuts. holds down units are provided with oversize pads to avoid impressions on sheet metal request. drive, clutch and brake:drive: motor, mounted on an adjustable platform, drives the large, cast-iron fly wheel through vee-belts. the power is further transmitted via fly wheel shaft to reducing gear box and then transmitted to main gear. gun metal bushes are provided all the rotating parts.clutch:rolling key clutch is linked with the main gear and engages every time when the foot switch is pressed.

front and rear gauges:front gauge: t slotted front gauge fabricated from mild steel is detachable.
rear gauge:rack and pinion type rear gauge provides accuracy and is easily adjustable to parallel and taper strips efficiently. blade:president shears are provided with high quality single or multi segment (hc, her) blade, with four edged.

finger guard:is fitted in front of hold down for operator's safety without any disturbing in operation viewing. lubrication:all bearing parts and guide surfaces a lubricated through connected oil cups and hand operated lubrication pump.

standard equipments:rear gauge, side squaring and front gauge, foot pedal, motor pully. gear & fly wheel guards and standard instruction manual, and spanner. standard accessories:electric motor, starter. vee belts, manual lubrication pump, front gauge, rear gauge with scale and stroke counter, electric and lubricating pipe fittings and wiring. power supply:400, 440 volts, 3 phase 50 cycles note: electrical items & blades are nor under warranty

specification

all dimensions are in mm.

product details: - frame: it is fabricated with prime m. s. plats. its interlocked construction where the bed is directly supported on the side walls, ensures consistent accuracy and perfect alignment. due to its generous proportions, it imparts ample strength to the complete assembly and ensures against deflection even while working at full rated capacity. ram and bed: made from steel plates of suitable thickness, machined for straightness and parallelism of the working surfaces. ram is guided and supported throughout the stroke by accurately machine guide ways.

drive system: power a transmitted to the ram through two individual gear drives for uniform load distribution throughout the length. this also reduces the torsional 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-alloy steel. ram adjustment:motorized ram adjustment is provided to facilitate quick and accurate adjustment of required bending angle. a spring-loaded dog clutch enables to angular setting of ram.

clutch and brake:clutch: press brakes are provided with high torque low-inertia friction clutch.brake: heavy duty mechanical brake ensuring immediate breaking of ram on releasing the pedal.clutch operating levers are designed in such a way that minimum engaging force is required at the pedal. front and rear gauge: front gauge: t slotted front guage fabricated from milled steel detachable. rear gauge:hand operated screw type rear gauge is provided to facilitate repetitive jobs.

lubrication:all bearing parts and guide surfaces are lubricated through connected oil cups and hand operated lubrication pump. standard equipments:standard v-block (die) and punch. front & rear gauge. motor pully, foot pedal, gear & fly wheel guards and standard instruction manual. standard accessories: electric motor control panel board, vee belts, push button pendent, stroke counter, manual lubrication pump, electric and lubricating pipe, fittings and wiring.

optional accessories: goose neck punch and other tooling (drowing as per required) power supply: 400/440 volts, 3 phase, 50 cycles. note: electrical items & blade are not under warranty.
