Definitions
- the invention relates to a Rollenindustrialumg for the wire guide between the finishing stands from Drahtwaiz Avenuen, consisting of a leading role pair, whose guide rollers are opposite each other, at the free ends of the Store swivel arms from double-armed levers whose lever bearings are fitted with a lever connected between the finishing stands of the rolling mill arranged supporting body are the, between the two-armed levers a centering funnel for receiving the wire rod, wherein the pivoting paths of the pivot arms about the lifting bearing Federverstell- and can be fixed, with arranged on the pivot arms, actuators supported against the support body (see, for example, JP-A-06047424).
- Guide rollers of this type serve the wire rod reliably in the Introduce guide rollers downstream caliber of the rolling mill.
- the leadership roles are aligned with the caliber center as close as possible positioned in front of the rollers because, apart from the high speeds, with which the wire passes the finished scaffolding of modern wire-lines, in this Section of the wire rolling mill to take into account the tight calibration tolerances is.
- the guide rollers must therefore still oval in this form of section Always grasp the wire cross-section to avoid tilting in the caliber submissions. This was done by adjusting the pivoting the swing arms of the, supporting the guide rollers, usually supported by leaf springs Double levers reached.
- the invention is based on the object, the known roller guides so Improve that the wire guide the constant cross-sectional changes automatically adapts.
- both of the guiding role facing away pivot arms with one, supported against the support body to provide pneumatic spring:
- the pneumatic spring which at a Stellverschiebung in a definable Always counteracts this shift with constant force, that a roller guide equipped therewith has different wire cross sections in can introduce the caliber and thereby both the wire rod and the guide rollers regardless of the size of the guided cross sections always with constant pressures are applied.
- the wire rod is going through this Adaptive roller guide free from play, regardless of the variations in cross section guided with constant force and it requires in certain wire cross-sectional areas no new hiring, with the result of time savings during rolling operation and corresponding reductions in operating costs.
- better tolerances also increased the service life of the guide rollers and their bearings and lead to further cost reductions.
- the swivel arms SA1a assigned to the rollers WL1 and WL2, SA2a of the double lever DH carry the two guide rollers FR1 and FR2 and, as well as the guide rollers facing away from these pivot arms SA1b and SA2b each against the support body TK supported actuators SEa and SEb.
- the pneumatic spring PF can be inserted into a corresponding receiving opening in the supporting body TK and secured with a clamping device KL.
- this pneumatic spring PF is not, as there, connected to the support body TK, but on the guide roller FR2 facing away from the swivel arm SA2B.
- the actuator SG of the pneumatic spring PF is supported here against the Carrying body TK from.
- the wire rod e.g. with oval cross-section, is from the centering ZT the of fed to the guide rollers FR1 and FR2 formed guide gap.
- This Guide gap is set by means of the actuators SEa, SEb and that way, that the gap width is smaller by an off-set than the desired cross-section of the wire rod.
- the pneumatic spring PF is in the receiving opening of the support body TK inserted and with the clamping device KL secured.
- the profile of the incoming wire rod in the guide gap opens then this gap against the pressure of the pneumatic spring PF to one, the current cross-section corresponding value.
- the pneumatic spring PF thereby causes that the guide rollers FR1, FR2 with the preset in this pneumatic spring Spring force to be applied.
- This spring force is thereby dimensioned that the guide rollers FR1, FR2 the wire rod, regardless of passing Wire rod sections with different diameter always with the same Apply pressure.
- the spring force of the pneumatic spring PF is there so dimensioned that the wire rod from the guide rollers FR1, FR2 safe led, but not rolled.
