Name Bush-pressing hydraulic press
Client M/S. Tractors & Farm Equipment Ltd., Chennai, India
Year 1992
Description This is a hydraulic press for press-fitting a metal-bush into a bore at the bottom of a heavy Centre-housing. This m/c is positioned in the middle of a roller-conveyor for the Centre-housing . The Centre-housing arriving on spring-supported-rollers is stopped and is pressed down by a hydraulic cylinder on an anvil in between two rows of edge-rollers. A mandrel carrying the metal-bush is at the bottom in the cavity of the anvil.  This is lifted up by a hydraulic cylinder and the metal-bush is press-fitted into the Centre-housing. Then finally the mandrel is retracted down and the hydraulic cylinder at the top of the Center-housing is released to enable the Centre-housing to be lifted on the edge-rollers by the springs, fortravel along the roller-conveyor. All these events are controlled by electrical sequential logic. The hydraulic power-unit is fixed at the side of the m/c and the electrical control-panel is fixed at the top of the machine-frame.
