Hydraulic press

forming

1.TYPES AND CAPACITIES:- presses are available in capacities of 10 to 300 tonnes in single geared. double geared ,ungeared ,”C” and pillar type models. Presses are also available in inclinable type and permanently inclinable type models. These machines are subjected to stringent performance tests using advanced testing devices to ensure high performance, increased productivity & reliability. Frame:- The robust frame is fabricated from soid steel plates with heavy cross ribbing to main housing & “C” supports for perfectly balanced distribution of stress over the cross section elimination deflection and vibration and thus improving die & machine life. Crank Shaft:- Eccentric crank shaft is machined from en-9 steel round bar. it is ground finished on bearing surface. The main crank shaft& eccentric bearing are covered with high quality phosphor-bronze or gun metal bushes and lubrication oil grooves for smooth functioning. PRESSURE REQUIRED FOR PUNCHING Pressure in tons for steel - Diameter of hole to punched in inches X Thickness of sheet in inches X 80 Pressure in tons for soft metal like brass etc. - Diameter of hole to punched in inches X Thickness of sheet in inches X 65 Specification of C- frame power presses in mechanical rolling key clutch & pneumatic clutch
