Straightening Roller Unit

Abstract

A straightening roller unit for steel material in wire, rod, or strip form that is to be straightened with straightening rollers cooperating in pairs, which are configured to be positioned against the material to be straightened and to be raised from it. The straightening rollers are driven, and the advancement force required for the straightening operation is introduced into the material to be straightened by friction of the straightening rollers.

1 . A straightening roller unit for steel material in wire, rod, or strip form that is to be straightened with straightening rollers cooperating in pairs, which are configured to be positioned against the material to be straightened and to be raised from it, wherein the straightening rollers are driven, and the advancement force required for the straightening operation is introduced into the material to be straightened by friction of the straightening rollers. 
     
     
         2 . The straightening roller unit of  claim 1 , wherein the straightening rollers are drivable individually or jointly. 
     
     
         3 . The straightening roller unit of  claim 1  wherein the straightening rollers are coupled to associated drive elements, which are drivable by a drive device via a driving-force distributor gear. 
     
     
         4 . The straightening roller unit of  claim 1 , wherein the positioning of the straightening rollers against the material to be straightened is executed without interrupting the nonpositive advancement engagement. 
     
     
         5 . The straightening roller unit of  claim 1 , wherein the straightening rollers are configured to be positioned against the material to be straightened and raised from it individually by hand or in motor-driven fashion. 
     
     
         6 . The straightening roller unit of  claim 1 , wherein all the straightening rollers are configured to be positioned against and raised from the material be straightened jointly by hand or via a motor-driven central adjusting device. 
     
     
         7 . The straightening roller unit of  claim 1  wherein the straightening rollers are embodied in smooth or profiled form. 
     
     
         8 . The straightening roller unit of  claim 7 , wherein the profile section of the straightening rollers is V-shaped, circular, elliptical, or any other arbitrary shape. 
     
     
         9 . The straightening roller unit of  claim 1 , wherein the straightening rollers are embodied as double-track straightening rollers for simultaneous or alternating straightening of two materials to be straightened guided in parallel. 
     
     
         10 . The straightening roller unit of  claim 3 , wherein the driving-force distributor gear has pairs of upper and lower gear wheels, associated with the straightening rollers, the axes of which gear wheels, like the axes of the straightening rollers, are coupled via rockers, and the lower gear wheels are supported in a main housing plate via double bearings, while conversely the upper gear wheels are supported in the same main housing plate via the rocker and a rotatably supported bearing housing and are coupled to a central adjusting device and an individual adjusting device. 
     
     
         11 . The straightening roller unit of  claim 10 , wherein both the individual adjusting device and the central adjusting device are arranged to be acted upon by a motor-driven actuator. 
     
     
         12 . The straightening roller unit of  claim 10 , wherein the individual adjusting device has an adjusting spindle, which connects the individual adjusting device to the central adjusting device. 
     
     
         13 . The straightening roller unit of  claim 1 , wherein at least one of the straightening rollers is adjustable transversely to the straightening plane by an actuator. 
     
     
         14 . The straightening roller unit of  claim 13 , wherein the actuator is actuatable manually, by motor, or in program-controlled fashion.
