Mechanical Pneumatic Press Brake Machine

MECHANICAL / PNEUMATIC PRESS BRAKE

JSMT Press Brakes are designed and developed through years of experience in sheet metal working machines JSMT Press Brakes are widely accepted in industries for continuous production runs and in areas requiring accuracy and repeatability coupled with high production.

FRAME : Frame is of robust steel construction of rigid and interlocked design. It is strain-free and supports the ram and bed against undesired deflection under permissible load condition.
RAM AND BED : Made from steel plates of suitable thickness. Machined for straightness and parallelism of the working surface. Ram is guided and supported throughout the stroke by accurately machined guide ways.
DRIVE SYSTEM : Power is 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 through a simple drive mechanism, facilitates quick bending angle adjustment angular ram adjustment is made simple by incorporating a spring loaded dog clutch.
CLUTCH AND BRAKE : All series of press brakes are provided with high-torque low-inertia friction clutch, synchronized with heavy duty mechanical brake ensuring immediate braking of ram on releasing the pedal. Clutch operating levers are designed in such a way that minimum, engaging force is required at the pedal. Electrically controlled & air operated clutch & brake combine unit permits high frequency of operation and more flywheel energy for work. Wear on clutch and brake is automatically compensated & no adjustment is necessary. Surge tank, filter, regulator, air lubrication unit, pressure switch etc. are incorporated. Pneumatic counter balancer are provided to counter the weight of slide & tooling which help in taking up the bearing clearances and easy slide adjustment
