Abstract

A roller guide for the guidance of the wire or rod between the finish rolling mill stands of a wire or rod rolling line. The guide has a guide roller pair which are mutually juxtaposed and journaled on free ends of pivot arms of double arm levers. The lever journals are connected with a support body between the finish mill rolls of the rolling line and which has a centering funnel for the rolled wire or rod between the double arm levers. The whereby the pivotal displacements of the pivot arms are settable and spring adjustable about the lever journals. The roller guide is improved in that the pivot arms have setting elements pressed against the support body and in that an adjustable-pressure pneumatic spring connected with the support body and bearing upon the pivot arm extending away from the guide roller or is connected with this pivot arm.

Claims

1. A wire or rod guide between finishing mill stands of a wire or rod rolling line, said wire or rod guide comprising:

an elongated support body located between finishing mill stands of a wire or rod rolling line and traversed by a wire or rod being rolled in said stands;

a centering funnel at an upstream end of said support body with respect to a direction of movement of said wire or rod therethrough;

a pair of double-arm levers journaled in respective fulcrum bearings on said support body and each having a respective pivot arm extending downstream in said direction from the respective fulcrum bearing and a respective pivot arm extending upstream with respect to said direction from the respective fulcrum bearing, the pivot arms extending downstream having respective free ends;

respective opposing guide rollers journaled on said free ends and engaging said wire or rod from opposite sides;

setting elements on the pivot arms extending downstream and pressing against said support body for setting a spacing of said guide rollers; and

an adjustable pneumatic pressure spring between one of said pivot arms extending upstream and said support body to apply an adjustable preset spring force to said rollers.

2. The wire or rod guide defined in claim 1 wherein said adjustable pneumatic pressure spring is connected to said one of said pivot arms extending upstream and bears on said body.

3. The wire or rod guide defined in claim 1 wherein said adjustable pneumatic pressure spring is connected to said body and bears on said one of said pivot arms extending upstream.
