The invention discloses an interlocking embedded type roll shifting cylinder connecting device. The interlocking embedded type roll shifting cylinder connecting device comprises a piston rod stretching out of a frame connection block through hole and is characterized in that two annular grooves are arranged at intervals in a free end of the piston rod; the free end of the piston rod is provided with two half thrust sleeves in a matching mode; inner walls of the thrust sleeves are matched with the annular grooves; outer walls at front portions of the thrust sleeves are of tapered shapes; back portions of the thrust sleeves are provided with annular flanges; tapered outer walls of the two half thrust sleeves are provided with an enclasping sleeve in a matching manner; the enclasping sleeve is connected with the annular flange via connecting bolts; end walls of back portions of the two half thrust sleeves are in contact with an outer wall of the frame connection block; the piston rod inside the frame connection block is in sleeve joint with an anti-rotating sleeve connected with the frame connection block via keys and bolts; and an oil sealing cavity is arranged between the two half thrust sleeves and the piston rod. Flexibility of the piston rod is enhanced by means of the oil sealing cavity. Service lifetime of the interlocking embedded type roll shifting cylinder connecting device is prolonged. Space is sealed and normal working efficiency is ensured.
Description
technical field [0001] The invention relates to a roll cylinder connection device, in particular to an interlocking embedded roll shifting cylinder connection device used in hot continuous rolling technology. Background technique [0002] In the process of hot continuous rolling, the connecting device of the roll-shifting cylinder and the piston-cylinder is connected by the traditional threaded connection method, and the invention is an interference fit. Not only the bolts are easy to loosen and fall off, but also the interference fit connection is very difficult to disassemble, and the piston rod Severe wear and tear. Contents of the invention [0003] The purpose of the present invention is to provide an interlocking embedded roll shifting cylinder connection device, which can avoid the problem of thread shedding caused by the traditional threaded connection method and the assembly and installation under the interference fit method during the actual application proc...
