Definitions

  • the machine in question has two guides, one on each side of the bar, to stabilize the position of same in the straightening process.
  • One of the objects of the present invention is to achieve automatic movement of a single control simultaneous with the movement of the upper roller and the lateral guide.
  • Another object of the invention is to position two rollers at the ends near the corners of the lateral guides in order to avoid wear of such corners of the guides in question.
  • the guides are automatically positioned, according to the diameter of the bar, since. by means of oscillating arches, connecting rods and bell-cranks, same are controlled by displacement of the base plate of the upper roller.
  • the guide-rules are perfectly accessible and are fixed by screws which can be replaced when they are worn out and they are protected from excessive overtaxing.
  • FIG. I is an elevational view of an installation which centrally comprises the straightener-polisher assembly of round bars.
  • FIG. 2 is a plan view of the machine illustrated in FIG. 1.
  • FIG. 3 is a side view of the center part of the straightener-polishcr.
  • FIG. 4 is a side view of the assembly by which the positioning of the lateral guides is controlled.
  • FIG. 5 is a plan view of the straightener-polisher machine.
  • FIG. 6 is a diametrical section of one of the two rollers situated at the ends of the lateral guides.
  • FIG. 7 is a'schematic view wherein two rollers, upper and lower, the bar being treated, as well as the two lateral guides, are shown.
  • FIG. 8 is a schematic view showing two positions for two different bars undergoing treatment.
  • FIGS. 1 and 2 in which an entry and exit table for the bar to be treated, is represented, the round bar straightener-polisher assembly is referenced I, while the groups which move the upper and lower rollers, are referenced 2 and 3, respectively.
  • the bar undergoing treatment is referenced 4.
  • FIGS. 3 to 5 The central part of the assembly, in which the straightening-polishing treatment of the bar 4 is carried out. is shown in FIGS. 3 to 5.
  • Two bridges or yokes which are each comprised of two vertical bars 5 and a horizontal bar 6, linked to each other by means of corresponding fixing elements, are also shown in the above mentioned figures.
  • coupling of the vertical element 7, whose height can be regulated by means of nuts 8 or similar. at the time of installing the machine. is provided.
  • the lower part of the member 7 is linked to a lever 10 whose end, in turn, is solidly connected to a horizontal shank 9.
  • the ends of this horizontal shank one of which is situated on each side as seen in FIGS. 3 and 5, have solidly connected bodies II which will be denoted heel-pieces or projections" with regards its lowcrmost part referenced 12.
  • Such heel-pieces are linked to lugs 13 by means of shafts 14.
  • the horizontal upper part of the table 15 was referenced 1.7 and it is here, in this part, where the corresponding guide 18 is situated, which guide is fixed by screws or similar to the table so that when said guides 18 are worn out by use, same could be substituted.
  • FIG. 6 The structure of one of the two small rollers 19, whose precise position can be seen in FIGS. 4 and 5, is shown in FIG. 6.
  • This pair of friction rollers is solidly connected to the upper part 17 of each table 15, at its area referenced 20, which is continued slantingly towards the exterior according the shaft 21 in which the bearing 22, surrounded by the roller 23 itself, are mounted and which corresponds to the active zone of the assembly.
  • FIG. 7 is a schematic view of the position of the corresponding bar, rollers and guides.
  • roller 24 is connected to the bar 4 and the upper roller is likewise connected to the upper part ofthe bar.
  • bodies which form the lateral guides 18, are provided on either side ofthe bar 4.
  • FIG. 8 schematically represents the positioning of the members which move when it is necessary to treat two bars of different caliber.
  • roller 23 drives and actuates the bar 4, in conjunction with roller 24, in such a way that it laterally disposes of the bodies which form the guides 18 mounted on the table 5, as is already known.
  • the lug 13 is driven by means of its shaft 14 at the heelpiece 12 which is duly driven by the lever or connecting rod 10.
  • the table 15, in question, turns to a corresponding angle to duly position itself in accordance with the bar 4 to be treated.
  • the spherical rollers of FIG. 6 were oppositely mounted near the lateral guides 18, so as to limit as much as possible. the wear of such guides precisely in said zones which are mostly affected.
  • a round bar straightener-polisher machine of the type including a lower rotary roller; the vertical position of said lower roller being fixed; an upper rotary roller positioned above said lower roller; a bar to be treated being longitudinally moved in a horizontal dircction between said lower and upper rollers; frame means supporting said upper roller for selectively vertically moving said upper roller toward or away from said lower roller to accomodate between said upper and lower rollers bars of differing diameter; a pair of lateral guide means positioned to contact opposite sides of a bar positioned between said upper and lower rollers for guiding such bar during movement thereof; and means LII for selectively moving said pair of lateral guide means toward or away from each other to accomodate therebetween bars of differing diameter; the improvement wherein:
  • said means for moving said lateral guide means comprises a pair of guide supports. one each having mounted thereon one of said lateral guide means, said guide supports each being pivotally mounted about shaft means for allowing pivotal movement of said lateral guide means about axes extending parallel to said horizontal direction;
  • control means operatively connected between said frame means supporting said upper roller and said guide supports for transferring vertical movement of said upper roller into pivotal movement of said lateral guide means about said axes.
  • control means comprises a pair of guide movement structures, each of which is connected to said frame means and one each of which is connected to one of said guide supports.
  • each of said guide movement structures comprises a yoke attached to said frame means. a lever pivotally connected at one end thereof to said yoke, a horizontal shank having fixed thereto a second end of said lever, said shank having at opposite ends thereof integral downwardly extending projections, and lugs fixed to the respective guide support and pivotally connected to said projections.
  • each of said guide supports comprises a table having an upper surface, the respective said lateral guide means being fixed to said upper surface.
