Sixty-ton Hydraulic Wheel Press — We illustrate herewith a hydraulic press specially adapted to the work of pressing into place boxes of vehicle wheels, and forcing on the hub-bands.
Owing to the fact that the pressures employed in this work are comparatively light, many machines for this purpose have been constructed with wooden frames, or with frames composed partly of wood, with the result that springing has occurred, and the machines have, in some instances, failed to work as well as a machine should be expected to work that is composed entirely of iron and steel, as in this instance.
The ram in this machine, which is 8" diameter, is placed below, the wheel resting directly upon it, while above there is a 3" adjusting screw, which can be moved by the hand wheel shown, to adapt the space to any length of hub, thus doing away with all necessity for blocking up.
The pump, which is made of phosphor bronze, is placed below, within the liquid reservoir, and Is very simple in construction, having but two valves, which are made of steel balls resting upon substantial seats. There is a relief valve, which opens when the desired maximum pressure is reached, and allows the liquid to flow back into the reservoir.
The pump is driven from a shaft at the top of the machine on which there is a friction clutch, by which the motion of the pump is at all times under perfect control of the operator. The pressure gauge shows both the total pressure upon the ram in tons, and the pressure per square inch.
The machines are intended to work up to 60 tons pressure and are tested up to 80 tons. The weight complete is 3,600 pounds, and the builders are the Defiance Machine Works, Defiance, Ohio. |
