Narendra Press- Tech Private Limited

Anand Parbat, Delhi

Mechanical power press It is designed for operation which require slow but high force at lower zone of the stroke, therefore perfectly suited for coining, extruding, sizing and thick plate blanking. By virtue of the linkage system, the ram speed is very slow as it approaches the BDC. This low punch entry speed allows enough time to provide plastic flow of material during critical cold forming zone.

FRAME

Welded steel construction, stress relived, computer aided frame design, extreme rigidity with uniform parallel deflection, ideal for progressive tooling, ensure high speed laminating precision and rigidity

SLIDE

The slide is guided accurately throughout the whole stroke with high precision eight way bearing guides free from backlash. Eight point, square corner gibbing provides long parallel guiding surface that maintain slide parallelism under off centre load resulting high precision & long tooling life

CRANK SHAFT

It is made from a forged piece of carbon alloy steel. Shaft is ground finished on bearing surface. All main bearing are of heavy walled nickel phosphorous and bronze.

DYNAMIC BALANCING

Provides better precision quality of lamination and longer life by controlling the thursh and vibration in the frame generated by crank shaft rotation.

PLUNGER GUIDE

The rotation of eccentric shafts creates front & back loads that changes guides clearance this is controlled by plunger guided design this eliminates change in guide clearance resulting high precision.

HYDRAULIC SLIDE ADJUSTMENT LOCKING DEVICE

This eliminates clearances inside the slide adjustment assembly. Maintain accuracy of slide travel at bottom dead centre.

STICK RELEASE DEVICE

Resolves tool jam problem, easy to operate

LUBRICATION

Motorised forced feed lubrication is of recirculating type ensures adequate oil supply, depending upon the bearing area ensures cooling of bearing as well as any fault in the system with cause instant stopping of the press and will be shown optically on control pannel.

Forging press Motor hp 150, Floor space (l-r X f-b) 14'3" X 12'2", Height above floor 18'9", Wedge adjustment, air clutch, Weight 330, 000 lbs. automatic lubrication, bottom knock-out.

• Digital Slide Adjustment Digital slide adjustment readout is recessed in front right slide of slide face and indicates the die height in 0.1 mm scale.
• Safe And Reliable Electrical Circuit
• Multi-checking electrical circuit design to ensure a safe and reliable operation.
• High Rigidity And Low Noise Design
• Less vibration and low noise. Increase tooling life and improve product's accuracy.

APPLICATION

Applicable to light, thin material, for single, and progressive die application in blanking, piercing, bending, forming, interlink with ROT line or transfer unit.

FEATURES

Straight side frame designed virtually eliminates angular deflection, providing increased precision for progressive die applications and reducing maintenance costs on tooling.

The slide area is 15 %25% greater than comparable C-frame presses to allow for larger tools. The large 6-point gibs are centered in the slide body, to provide better resistance to off-center loads.

User friendly , multi-function control system allows for easy integration of auxiliary equipment and automation.

THE HIGH RIGID FRAME

Welded steel construction, stress relieved, computer aided frame design extreme rigid to avoid angular and elongation deflection of the frame.

COMPOUND CLUTCH & BRAKE

This high torque performance compound clutch & brake ensures movement slide quick stops at precise position, the production is therefore fast and safe.

HYDRAULIC OVERLOAD SAFETY DEVICE

This series of presses from 63250 tons are all equipped with hydraulic overload safety device instantly goes into emergency stop mode to protect the die and the press, without concern about die jam.

SLUDE ADJUST MOTOR/DIE HEIGHT INDICATOR

This series of presses from 63250 tons are all equipped with easy to use motorised slide adjuster, and the slide depth is locked by a unique penumatic macanism. Easily and quickly adjust accurate die height by pushing up and down buttons on the operation stand and easy to read. Die height indicator is also installed in the slide.

SIXFACE WIDE AND LONG GUIDE

The guide rail is made of phosphorous bronze which is excellent resistance and ensures smooth and accurate slide movement. Not only improves work efficiency with perfect production quality but also extends life.

BALL ROD

The ball rod is made of EN24 alloy steel for longer duration. Extra aluminium bronze is added as its nut for accurate movement without sudden changes.

Mechanical press are all equipped with hydraulic overload safety device instantly goes into emergency stop mode to protect the die and the press, without concern about die jam.
