Definitions

  • This invention relates to a device preventing the rotation of longitudinal advancing rods particularly for straightening and bending machines.
  • stirrup machines work continuous feeding rods or bars or wire, by using straightening and roll advancing means, and bend and shear the advancing material into stirrups, (Italian Patent No. 1 024 224 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 raw material to be worked is hot milled rod, causes an uncontrolled rotation for different reasons e.g.:
  • FR-A-2138 615 which discloses the features of the pre-characterizing part of claim 1 utilizes straightening means structure rotating around the deviated raw material, so it is practically impossible to keep the advancing bar from rotating. Slightly uncontrolled rotation, by twisting action, caused by said rotation of the complete structure around the raw material, cannot be avoided.
  • this problem is solved by providing a device for straightening rods or wire without relative rotation of succeeding elements of material about the longitudinal axis, said device comprising:
  • the opposed rolls are "V" guttered.
  • Figure 1 is a schematic view of the traditional stirrup operating 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 represents schematically the continuous arm lever applied on the advancing rod by a not represented straightening means
  • Figures 7-10 are other various disclosed solutions without respective straightening means between the deviating points
  • Figure 11 is a schematic perspective view of the device embodying the invention, that can be placed between the uncoiler and a bending device in stirrup machine (not shown)
  • Fig. 12 is a transversal schematic section of an advancing rod corresponding to one of the two opposite guttered roll guide means.
  • Figure 1 shows that in prior art, a stirrup machine generally consists of: a rod coil feeder (A), a horizontal rolling straightener means, one in horizontal plane (B 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 utilizes the system of deviating roll means (R) with an inclined continuous arm guide lever (L-p Fig. 6) comprising at least one deviation roll (1) the continous arm lever (p) being placed upwards or downwards of said deviating roll (1) on the advancing rod (b) (Fig. 6 to 10).
  • This solution to utlize an inclined continuous arm guide lever means has 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 (1'), 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 other combined shapes.
  • Deviation devices for each angle deviation (R, R') form individual deviation units (F) for the advancing rod.
  • At least one straightening roll adjustable in position (2) in order to "straighten” the rod is utilized downstream of the deviation device (R).
  • deviation units can work in couples (F), one in horizontal plane (F) and one in vertical plane (F') as represented in Fig. 10.
  • a guide bar unit (3) can be placed in order to avoid flection of the advancing bar (b), reinforcing the adjacent continuous arm lever (L), said guide bar being straightening means in the feature of groups of guide rolls as represented with (c, c', c") in Fig. 11.
  • the first deviation device (R'%@be movable as represented in Fig. 10 to vary the angle of deviation in association with straightening means (3), depending from the left or right coil developing and in compliance to the utilization of one or two rods.
  • the device comprises:
  • the first working plane (A) is horizontal or approximately horizontal and the second (B) is vertical or approximately vertical.
  • the first roll straightening arm means (c) placed between the deviating angles, is adjustable in its inclination to vary the rod deviation angle up to 90°.
  • the series of upper rolls (3) of each group of guide rolls (c, c', c") are adjustable in pressure by manually controlled means (4), against the opposing rolls (2), being staggered not aligned.
  • each group of guide rolls (c, c', c") and the opposed rolls of said realigning and guide means (e, e', f) have V-shaped rims for the advancing rod (1), 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).
  • the couples of advancing rolls can be adjusted in order to apply less pressure on the rod.
  • Said rod roll reangling means comprise a couple of inside apex angle anvil rolls (8, 8') and an adjustable opposed pressure roll (7).
  • One of said anvil rolls (8') is enclosed upwards the second and the third group of guide rolls (c', c").
