MECHANISM OF CONICAL SKEW ROLLING FOR MANUFACTURING SEAMLESS TUBE

Japanese Patent JP2013121620

A

To enable especially rapid assembling and removing for changing conical rolls by simple or plain structural form.

In a mechanism 7 of conical skew rolling for manufacturing a seamless tube, that is formed as a mechanism of diescher rolling which includes two conical rolls 6a, 6b arranged inside a rolling stand 1 installed on a foundation 3 and driven, and two guide disks or diescher disks 15a, 15b to be driven, the conical rolls are provided symmetrically about the axial line 4 of rolling and arranged side by side horizontally inside the rolling stand, and the respective side faces of the rolling stand which are parallel about the axial line of rolling include assembling windows 5a, 5b in which the assembling pieces 8 of the conical rolls are housed and guide stands 10a, 10b for housing stand side face closing covers 12a, 12b which can be elevated and lowered, and the stand side face closing cover is made to support a roll adjusting means 11 for the conical rolls.
