ABSTRACT:
A rolling mill is characterized in that three hydraulic actuators, positid in a mill frame and comprising yokes with attached rolling tools therein, are provided with a piston rod having two pistons. The outer piston co-operates with an external cylinder which is mounted on a body of the actuator by means of a threaded joint. The inner piston co-operates with an internal cylinder attached slidably within said body.
At one end, the piston rod is provided with a thrust flange being in contact with spacer washers mounted on the external cylinder, whereas the opposite end of said piston rod includes a stop positioned in a seat of a slider, said stop co-operating with a shoulder on said slider. The slider is mounted slidably on a bottom of the internal cylinder, the end portion of said slider having a pressure flange to press down a tool yoke to the bottom of the internal cylinder during rolling operation.
This invention provides an adjustable rolling mill with an accurate and dependable tool setting, in addition to a simple and time-saving replacement of the tools.
