Link Motion Presses
Ravi Power Press offers a mechanical press in the form of Link Motion Presses, comprising a variable drive arrangement. The press boasts of a main gear which drives a crankshaft. The press is obtainable to first shift the slide toward the work piece at high speed, and subsequently get the work done at low speed before quickly retrieving the slide. As soon as the slide slows down upon moving to the working zone for the period of the stroke, there are much less vibration, noise, and heat from the friction between the compared with those crank presses.

Slide Speed Curve Comparison
Operation : Drawing
Height : 70 mm
The slide block's engaging speed link motion press is reduced by 40% to that of crank shaft press.
Height : Enhanced accuracy & stability of product. Border selection criteria on material with slower engaging speed of slide block, the wear out resulted from heating of die & the loss of oil film on the surface of product are greatly reduced. The scratch on the surface of the product is less through the characteristic movement of slide block, the high production volume and low wear out are achieved.

Suitable for drawing, bending process.

Slide Speed Curve Comparison
Ravi Power Press

Operation : Drawing
Height : 3.2
The slide block's engaging speed of link motion press slowers by 40% against that of conventional crank press.
Height : More accurate and stable quality with slower engaging speed, the high temperature resulted in friction between die & work pieces is less than the crank shaft press; this greatly extends the life of die elements.

Suitable for piercing stamping, sequence precision process.
