The single frame is of steel welded construction. It is made from fusion-welding quality steel and is fully stress relieved. The deflection of frame is kept within close limits by well chosen design parameters. This helps in maintaining close clearance between Die and Punch, resulting in quality stamping and increased tool life.
The box type construction of the slide is designed for maximum rigidity. The pitman connecting links using ball joints are designed for maximum weight, also giving slide adjustment setting accuracy upto 0,025 mm. This helps faster machine set up & improved tool safety during set up.
Pneumatic Counter Balances are provided to counter the weight of the slide and tooling which help in talking up the bearing clearances and further ease slide adjustment.
A lockable selector switch for ONCE, INCH & CONTINUOUS mode of operation is provided. The press is equipped with highly reliable Dual Solenoid Valve which prevents faulty operation by electrical lockout. ‘Top Stop’ to stop the press at Top Dead Center, Two Hand Engagement Device, ‘Emergency Stop’ are some of the other standard features.
The precision ground crank shaft, rotating in extra thick walled nickel-phosphor bronze bearings, is driven through a pneumatic clutch-brake combination. Specially designed extra supports lift the main shaft assembly to balance it evenly at both ends. This also allows pre-loading of main bearings in the direction of load to desired extent, thereby extending the life of the main bearing bushes. The flywheel is driven by an energy-efficient AC variable speed drive. A digital readout on the panel indicates the strokes per minute of the ram.
Reciprocating machine cause higher dynamic loads, so in case of a spring supported system a fairly big foundation may become necessary to keep the motion response low, this way vibration and structure borne noise can be avoided.
All essential points receive adequate quantity of pressurised metered oil through a motorised central lubrication system. This system is interlocked with the main press control. As a further safety, it is so arranged that the press can be started only with a “delay” after lubrication has started.
