Definitions
- the invention relates to a device for guiding rotating about its longitudinal axis blanks emerging from a cross rolling mill, in particular woodlice mill.
- a device for guiding the Luppe suggested that at least two should cover the entire maximum Tube-length-extending tubular guide rollers, which is characterized below the run-out level of the blanks parallel to the blanks run-out direction are arranged side by side rotatably mounted about their longitudinal axis.
- the basic idea of the present invention is accordingly one to create continuous rotating tubular guide for the leaking bob, which ensures that the spirally tapering bob is as unimpeded as possible, however leaves the rolling mill optimally guided.
- the continuous guide roles can easily absorb fluctuations in diameter at the outgoing die, one Twisting in thin-walled long blanks is caused by the rotating Avoid leadership roles safely.
- tubular guide rollers each have an end face are stored, as is already practiced for example with roller cooling beds.
- the tubular guide rollers are provided according to the invention and / or the support rollers by drives synchronized with the die outlet speed to spin. This avoids torsional forces acting on the plate.
- the bobbin can be spread evenly on both Guide rollers rest and are supported by them at the outlet.
- the Guide rollers on inclined, symmetrical to the center of the roll Adjustable guide carriage.
- This slide can adjust the height and the distance at the same time the guide rollers vary from each other, so that also strong in diameter different troops can be safely guided.
- vertical above the tubular guide rollers above the flap several that can be put on the flap jacket and for evaluating the Luppe together swivel-away short guide rollers are provided.
- This Guide rollers prevent the leaking slug from breaking out of the side Rest on the tubular guide rollers.
- each around a horizontal and transverse Axis extending to the hole outlet direction can be driven in rotation.
- This Disc rollers become after the upper short guide rollers are swung away swung in from below and lift the slug off the tubular guide rollers from to in a known manner on the circumferential grooves of the disc rollers up to Transport transfer position to a removal device. After that the Completely rolled billet in a known manner, for example via a swivel lever ejected.
- the present invention provides an optimal guiding device for the spiral leaking slugs and is particularly favorable for thin-walled slugs applicable. With these thin-walled blanks, the risk of twisting in conventional guideways can be safely avoided, a danger of The bend is buckled by using the continuous guide no more.
- the only drawing figure shows a cross section through an inventive Contraption.
- the spirally tapering cap 1 is separated by two lower ones preferably offset by 30 ° from the horizontal outlet plane Guide rollers 2 out.
- the guide rollers 2 are over the maximum to be rolled Bead length (e.g. 15 m) designed as a continuous guide tube.
- Each at the end is the radial bearing 3 of the rotatable tubular Guide rollers 2.
- To support the guide rollers 2 are in corresponding Intervals lower support rollers 4 attached. If necessary, the tubular Guide rollers 2 with a synchronized to the outlet speed of the die 1 Drive are driven.
- the dimension-dependent setting of the tubular Guide rollers 2 take place centrally to the center of the roll individually via correspondingly inclined ones Guide carriage 5 or together with smaller diameter differences an outside pivot.
- the upper short guide rollers 6 are swung out, and in a position shown in 6.1.
- the between the tubular Guide rollers 2 arranged driven disc rollers 7 are used for Longitudinal transport of the slug 1 restricted, which raised the slug and into a Transfer position is transported.
- There the finished roll 1 is over a retractable lever 8 ejected laterally.
