Description

Guide for rod-shaped rolling stock The invention relates to means for safe insertion of ovals, skewer edges or similar cross-sections in rolling mills.

It was previously common practice to have the oval and skewer leads towards to employ the roller axis, with the left guide half mostly fixed and the right half was movable. The split of the guide halves was done for this reason in the major axis of the relevant profile. Something unequal, shifted Profile and especially with slightly colder roll bars, the adjustable guide half easily evade and tilt, which always results in an imprecise or rolled seam Rolled stock was brought out. There was also the appointment of the flexible leadership very cumbersome and time-consuming, without it - an unconditional accuracy of the employment to ensure.

According to the invention it is proposed that the introductions for oval and similar rods instead of subdividing in the major, inversely in the minor axis, whereby the employment of the movable guide half is vertical and pivotable happens to the roller axis.

In the drawing, the invention is shown by way of example.

Fig. I shows the implementation of an oval lead-in that has been used up to now in cross section. Fig. 2 shows the introduction according to the invention.

Fig. 3 shows the introduction in a longitudinal section. Fig. 4 is a Cross-section of Fig. 3 along the line 4-4.

Figure 5 shows a schematic arrangement of the introduction in front of the rollers.

The subject of the invention illustrated in FIGS. 2 to ... consists of a rather lower fixed introduction a and the upper movable guide b. While in the known versions (Fig. I) the rolling rod to be guided was grasped and held on the broad sides, according to the invention, the profile to be guided in the two guide halves a, b at its apices or shoulders c, d, e, f includes and held, wherein the guides a and b are guided in the housing g to close, so that a lateral deflection or tilting of the roller rod is excluded.

The upper movable guide is inserted into a clamping head h guided in the housing g, by which it is held. The clamping head h can be lifted and swiveled out by eccentric i or similar devices in the direction of the longitudinal axis of the roll rod to be guided or at right angles to the roll axis built into the housing g. Both the clamping head h and the housing g can be made in two parts in order to facilitate installation and removal.

Fig. 5 shows schematically how the upper guide works b. By moving the eccentric levers connected, for example, by a rod l h backwards the guide b lifted and swiveled out at the same time. In this position b1 (shown in dash-dotted lines) the rolling rod can easily between the guide halves are inserted, whereupon the upper guide b is pivoted back and. is placed on the roller bar. .

Once the rollers have gripped the bar, the top guide-b due to the friction generated between the incoming rolling rod and the eccentric Employment dragged along until they are tight with their side stop lugs j against the housing g. This stop can be adjusted by means of adjustable wedges or the like. Like. Easily regulate so that any wear on the guides can be compensated for can without it being necessary to change the guides. Remains in this position the guide always pressed firmly on the roller rod, whereby the same through the Never change the situation given by leadership. can. As a result, the rolling pass is always go through properly and ensure a flawless rolled product.

Even with very crooked ovals, which are in the previous way do not let it roll out, is always a flawless one with guides according to the invention Rolled product achieved by evading the guide and a tipper or turning over of the rolled bar introduced is completely impossible.

PATRNTANSPIZÜCHE: x. Guide for rod-shaped rolling stock, characterized in that the guide jaws (a, b) for oval or similar calibers are divided in the small profile axis, so that the rolling rod to be guided ° at its apices or shoulders (c, d, e, f) of the profile recesses of the beiden'e guide jaws (a, b) which is the upper guide shoe (b) is clamped in a clamping head (h), which in turn sits closing in the guide housing (g) in the direction of the roll axis. a. Guide according to claim z, characterized in that the upper guide half (b) is arranged so that it can be moved eccentrically at right angles to the roller axis, the guide comprising the roller rod being pulled by the incoming roller rod against a stop (j) so that a uniform, continuous and almost automatic pressing of the roller bar between the guides (a, b) is effected.
