Definitions

  • This invention relates to a Device preventing the rotation of longitudinal advancing rods particularly for straightening and eventual bending machines.
  • stirrups works continuous feeding rods or bars or wire, by using straightening and roller advancing means, and bends and shears the advancig material into stirrups, (Italian Patent no. 1024224 in the name of Del Fabro).
  • Other machines are realized not for bending the raw material but only for straightening and shearing into stock.
  • raw material continuous feeding rolling means particularly if the row material to be worked is hot milled rod, causes an-uncontrolled rotation for different reasons e.g.: - the anisotropy of the material, a section not perfectly round, superficial imperfections, residual stresses, etc.
  • a preferred embodiment disclosed in the Italian Patent Application No.83472A/83 filed on October 12.1983, utilizes traction pliers means that hold the raw material in position so it does not twist.
  • the limit of this deviation is not more than 90° because a higher limit causes deformation and more power for working, although smaller diameters (millimeter or less) also 180° can be used.
  • the advantages offered by the invention are mainly that the rod is held in position contiuously by use of said inclined continuous guide arm lever.
  • This solution can be realized in a new performance of well known roller straightening means this ones being placed in vertical and/or horizontal working plane.
  • a rod roller advancing means is placede, and further downwards from said final realignment means, a rod adjustable opposed rolls guide means is utilized to realign the rod in its said working pathway line.
  • said first inclined rod roller straightening guide means is adjustable in the respective inclination.
  • each roller straightening guide means is adjustable in pressure.
  • the opposed rollers in said deviating angles are "V" guttered.
  • said realigning means have a pair of apex inside anvil rolls and an opposite adjustable pressure roll means, to allow adjustability of the straightening on the rod for realignment.
  • Figure 1 is a schematic view of the traditional stirrup operanting devices
  • Figure 2 is a side view of the twisting of a traditional stirrup
  • Figure 3 is a perspective view of a twisted stirrup
  • Figure 4 is a well known curved deformation (in exaggerated continuous bending) of the raw material/rod/wire in drawing condition
  • Figure 5 is an orthogonal view of the rod between two rolls to show one of the causes of its rotation during advancing
  • Figure 6 is the continuous arm lever applied on the advancing rod
  • Figure 7-10 are various other solutions
  • Figure 11 is a schematic perspective view of the device that can be placed between the uncoiler and a stirrup or straightening devices (not shown)
  • Fig. 12 is a transversal schematic section of an advancing rod corrisponding to one of the two opposite guttered roller guide means.
  • Figure 1 shows that a stirrup machine generally consists of: a rod coil feeder (A), a horizontal rolling straighter unit, one in horizontal plane and the other in vertical plane (B'); a pair of roll advancing means (C), a shear means (D); a bending means (E) with guiding fork (f) and bending nib (n) that rotates to bend the rod (b) into a stirrup (s).
  • the invention realizes a deviating roll means (R) with an inclined continuous arm guide lever (L) utilizing at least one deviation roll (1), being the continuous arm lever (p) placed upwards or downwards of said deviating roll (1) on the advancing rod (b).
  • This solution to utilize an inclined contiuous arm guide lever means have the scope to increase the length of the respective arm lever (L) as represented in Fig. 6.
  • the angle of deviation (i) of the rod (b) can be realized between 10° and 90°.
  • two deviation rolls (1) may be used as in Fig. 7 and with auxiliary use of counter rolls (I'), more deviation rolls can be used (1) and respective counter rolls (1') as indicated in Fig. 8-10.
  • the advancing rod can be deviated to "Z" shape (Fig. 7,8), or loops or others combined shapes.
  • Deviation devices for each angle deviation (R,R') form individual deviation units (F) for the advancing rod.
  • downwards of the deviation device (R) is utilied at least one straighting roll adjustable in position (2) in order to "straighten” the rod.
  • deviation units works in couples (F), one horizontal(F) and one vertical (F') as represented in Fig. 10.
  • a guide bar unit (3) is placed in order to avoid flection of the advancing bar (b), reinforcing the adjacent contiuous arm lever (L).
  • the first deviation device (R') is movable as represented in Fig 10 to vary the angle of deviation, depending from the left or right coil developping and in compliance to the utilization of one or two rods.
  • the device of this invention comprises:
  • the first working plane (A) is horizontal or aprox horizontal and the second (B) is vertical or aprox vertical.
  • the first roller straightening guide means (c) place between the deviating angles is adjustable in its inclination to vary the rod deviation angle up to 90°.
  • each roller straightening guide means (c,c',c") inclined on the side between the deviating angles are adjustable in pressure by manually controlled means (4), against the opposing rolls (2), being staggered not aligned.
  • Said containment gutters of said rolls are in a "V" with angle conceived in order to allow the working of a range of rod diameters (1).
  • the advancing means (d) is realized by a single pair of opposed rolls (5,6) being at least one (6) adjustable in pressure against the opposed one (5).
  • Two couples of advancing rolls can be provided in order to apply less pressure on"the rod.
  • Said rod roller reangling means comprise a couple of inside apex angle anvil rolls (8,8') and an adjustable opposed pressure roll (7).
