adjusting roll in rolling frames, among others vertical upset forging frames, and method of its operation (embodiments)

摘要

The invention relates to an adjusting roll for the rapid adjustment of rolls in rolling frames, among others vertical upset forging frames, comprising al least one respective piston, which acts on both sides of a working roll to adjust the latter, by means of assembled parts of at least one working roll or an interposed support roll. The inventive adjusting roll has been improved by the provision of a piston (1), which is equipped with two piston rods (2, 3) that point in opposite directions and the piston or pistons (1) are inserted into a respective cavity in the roll base (5) or roll cover (4). said base and cover comprising coaxial bores for conducting the piston rods (2, 3).
