Frame
The frame of PARKASH Screw Press consist of four steel casted frames, held together by four
hydraulicaly pretensioned tie rods, and thus ensuring longevity of the frame, and forming of more accurate parts, and reducing the overall weight and size of the press.
Screw is made of high-alloy forged, quenched and tempered
steel which provides longer screw life. The screw bearing in the
machine frame is a heavy-duty spherical flanged bearing.
Screw Nut
Screw nut is of special wear resistance bronze alloy fixed in the ram.
Thread geometry in the screw drive with optimized tooth profile and four
start threads, has already proved to be durable and tough in the past.
Motors and Driving System of the Press
The drive comes from two heavy-duty high torque motors linked via a bull gear to the external diameter of the flywheel. The press force is limited by a slipping clutch provided in the flywheel.
Foundation
Optional spring damping foundation pads under the mild steel bed plate ensures low vibration during press operation.
Lubrication.
Screw, thrust bearing and guides are continuously lubricated by re-circulating oil
lubrication system.
Safety
PARKASH Servo Screw Press is equipped with digital
tonnage monitor in which the force exerted in forming process is measured and recorded by strain gauges. When the maximum permissible force is exceeded, the
system displays a warning message and cycle stops, to prevent possible damage to the press. Photoelectric sensors mounted on both columns front and back.
Ram and Guiding System
Ram is of high-quality cast steel and is guided in four guides at
45 degree with continuous lubrication, so that it is able to
maintain constant clearance in spite of heat expansion. Bronze
and steel are used as guide pairs.
