  • This invention relates to devices for turnprising a plunger with a tapering head which moves lengthwise in the direction of tilting and grips the ingot between itself and an abutment.
  • the plunger When the plunger is thrust forward against an ingot lying on the roller track of the rolling-mill, it is intendedto Carry with it theside of the ingot remote from the abutment, a certain grip being exerted owing to the space between the plunger and the abutment diminishing.
  • the abutment is a counteracting plunger with a tapering head.
  • these devices have the disadvantage that they can .only be used for tilting billets of particular cross-sections, more particularly of elongated cross-section, since both plungers move in guides that cannot Shift laterally, and so the space'between the gripping surfaces must continually decrease as the plungers are thrust forward.. As a consequence of this, for many cross-sections of billet the grippng pressure becomes so great after a small angle of tilt that the billet is jammed between the plunger and abutment.
  • the present invention provides for turning ingots, billets or the like of any crosssection through any desired angle; according to it, the abutment' or the plunger is held yieldingly' under load by a gripping force mension of the billet as it tilts.
  • the gripping force is overcome by the jamming pressure and the abutment or the plunger yields laterally. So it is impossible for a billet of any cross-section to become jammed, and any indenting of the billet that may occur where it is gripped is so small that it will be rolled out.
  • the billet may possibly Shift along the abutment when the plunger advances to tilt it. This may be prevented by inclining the working surface of the abutment to the vertical and towards the plunger. The pressure of the abutnent then has always a vertical downwardly directed component. 2
  • the plunger and abutment are Inounted on the slide running cross-wise of the billet beneath the roller track, in such a manner that they can be raised and lowered.
  • The' abutment can be readily and quickly presented against the billet to be turned, and the tilting plunger then thrust upward.
  • two plungers are employed having tapered heads and eachcapable of being raised and lowered; according'to the direction tilting, the' one of theni is thrust upwardfor tilting while the other yieldingly held plunger serves as the abutment. It is advantageous to pivot one plunger about an aXis parallel with the billet.
  • the teeth' of both plunger'heads are directe-d towards the roller track, since each-plunger mayserve as A the -abutment, and either one may be thrust forward in the same direction according to the desired direction of tilt.
  • Fig. 1 is a diagramr'natical partial longi- V tudnal section through one preferred form i of onstruction
  • Fg. 2 shows a modification of the plunger heads on a larger scale
  • FIG. 3 shows the same modification used for tlting in the opposite direction
  • Fig. 4 shows another Construction of the adjacent faces of the heads illustrated in u Figs. 2'and 3.
  • the plane of the roller track is indicated in the figures by the line X-X.
  • a carriage 2 Beneath the roller track a carriage 2 is mounted on .fixed rollers 1 so as to be movable trans'versely to the billet as indicated by the arrow P.
  • Two plungers 3, 4 are located side by side npon the carriage, longitudinally movable in .guides 5, 6.
  • The' guide 6 of plunger 4 is Secured in vertical position upon the'carriage 2 anda shaft 9bears'a toothed wheel 7 engaging in a rack 8 upon the plunger so that the plunger' is mo'va le vertically 'up and down.
  • the guide 5 of plunger3 is revoluble upon a shaft 23-mounted in a fixed bracket 21 of the cari riage 2 parallel with the billet'to be turned.
  • 'A rod 10 is pivotally connected with the upper part of the guide 5 and at its other end to the short arm 11 of a bellorank lever which rotates upon a pivot 12 on the guide 6 and carries on its longer arm 13 i a weight 14 by which the plunger 3 is pulled I toward the plunger 4.
  • the plungers 3 and 4 are kept a certain minimum distance apart by adjacent stops 15, 16 thereon.”
  • the heads 17 18 of the plungers 3, 4 are formed as rollers revoluble about axially project'ng pivot bolts 26, 26' of the plungers.
  • the heads of both plungers taper towards the top, the head 18, however, having a curved taper while the head 17 is an ordinary trun-' cated cone ⁇ y
  • the head 17 of plunger 3 Prior to the tilting of the billet 19 lying on the roller track, which billet is shown by way of example as having a'rhomboidal cross section, the head 17 of plunger 3 is in the osi-tion shown in dot-and-dash lines in ig, 1 while the head 18 otplunger 4 is in the 'position shown in full lines in said figure; that is to sa roller track.
  • the billet 19 is to be turned in the direction of the arrow Y, Fig. 2
  • plunger 3 is raised by nechanism (not illustrated) serving to rotate the pinion 24 until it projects, above' the roller track X-X, and
  • the carriage 2 is then moved transversely until the head 17 Contacts with the billet.
  • the plunger 4 is now also raised until its head engages the billet 19 as indicated in full lines in Fg. 2.
  • the plunger 4 is raised further the billet l9 turns into the intermediate position'shown in dotted lines in Fig. 2 in which it is grippedlbetween the heads17 and 18, the
  • both heads are below the i would be indented'on the further raising' of plunger 4 unless plunger 3 were movable transversely to the roller track. Since, however, in accordance with the invention, the head 17 is held against the billet 19 with 'a regulable pressure determined by the weight 14, it can yield, .and does yield, whenthe further raising of the plunger 4 increases the gripping pressure to such an extent that crushing of the billet might occur. It thus comes into the position shown in' dot-anddash lines in Fg. 2, the plunger 3 rotating about its shaft 23.
  • the distance between the two heads 17, 18 diminishes .until the gripping pressure has reached a'predetermined' amount, whereupon the distance is 'automatically again increased'so thatindentation of the billet at the point where it is gripped is avoided or at any rate is so small only that it will certainly disappear in further rolli'ng'.
  • 'Billets of any cross-sections whatever may be tilted with the* aid of the improved turning device through any angle without damage to 'the billet.
  • the grip upen the billet is' so far slackened by slig'ht withdraw'al of the plunger 4 that the billet can be carried forward by the roller track, the heads 17, 18 guidng the billet in its tilted position.
  • both plungers 3, 4 are withdrawn by means of thepinions 7, 24 until they lie beneath the plane -X.
  • Their heads'17, 18 are then not expsed to the blows ofthe tail endof the 'billet 1 9 'and also they do jot interiere with the creases until in the position shown in dotted lines the gripping ressur'e is so great that on further advance of the head 17 t overcomes the ressure exerted by the weight 14. ⁇
  • the hea 17 then yields so as to permit tilting of the billet without damage into the sition illustrated in dot-and-dash lines in Fg. 3.
  • the part of the surface of the truncated conical head 17 which contacts with the billet 19, may be perpendicular to the roller track as shown in Fig. 1,' that is to say, it may be vertical. But if the friction between the head and the billet is too small, the billet may possibly be lifted from the roller track which is not desired. 'Inthe construction shown in Fig. 2, this possibility is obviated by placing the head 17 at such an angle to the vertical that when tilting the part of its surface contacting with the billet' is inclined to the vertical and towards the plunger 4, say for example by an angle a. When the plunger 18 is advanced, the counter-pressure on the billet 19 has then a .downward Component which prevents the billet lifting.
  • Lifting of the billet may also be prevented as indicated in Fig. 4' by making the surface of the heads 17, 18 toothed, the points ojthe teeth 20 being directed downward and so acting to 'restrain the billet from upward movement.
  • the heads 17, 18 of the plunger-s 3, 4 may alternatively be fast upon' the plungers.
  • the stroke of the plunger is substantially the same for the same angle of tilt whether the billet be of large or small cross-section, so that the plunger describes the same workin path. This materially simplifies control o the device.'
  • a'device for tilting ingots or the like work-pieces the combinaton with two plungers having tapered heads between which the work-piece is gripped, either of said plungers serving as an abutment, of means consisting of a weightedleveroperatively attachedto one of said plungers for yieldingl holding it up to its work by 'a' gripping orce actng transversely to the work-piece.
