Definitions

  • the present invention relates to a drawing assembly intended for being applied in machines for working metal sections, in particular iron rods for reinforced concrete, according to the preamble of claim 1.
  • the shaped rods used for example to produce frames for reinforced concrete are generally obtained from metal sections constituted by iron rods, in coils or bars. To this aim metal sections are supplied, one by one or in groups, to manufacturing machines which automatically perform the mass-working of the desired products.
  • cutting and bending machines are currently known, which are able to realize finished products, such as bars, stirrups and shaped pieces, from metal sections, in bars or coils.
  • These manufacturing machines generally provide for a drawing assembly positioned along a suitable feeding line, a cutting assembly for the sections in order to have irons cut to size, and if necessary one or more bending assemblies to have irons bent according to the specific requirements.
  • straightening members of any type for example of roller, rotor or hyperbolic type
  • the sections are inserted in the insertion zone of the working line according to a predetermined progress direction.
  • the straightening operation is often performed by means of different sets of straightening members, which sometimes, as in the case of the straightening rollers, act on differentiated planes, for example on two orthogonal planes, substantially horizontal and vertical, in order to correct corresponding bending components.
  • the horizontal straightening members, in which the cited counter-rotating rollers are positioned on a substantially horizontal plane are positioned upstream of the drawing assembly, while the vertical straightening members, in which the cited counter-rotating rollers are positioned on a substantially vertical plane, are positioned downstream of this drawing assembly.
  • the drawing assembly is in its turn generally constituted by couples of counter-rotating superimposed wheels or idle wheels.
  • the drawing strain depends on different parameters, at the same conditions of which it surely increases by the diameter increase.
  • the contact surface between the sections in progress and each couple of drawing wheels is limited, so that the specific pressure turns out to be very high and by diameter increase the strength limits of the material itself are exceeded, causing thus considerable damages.
  • building materials are concerned, which for reasons of rules and safety have to result intact, this problem is of primary importance.
  • a consequent disadvantage is constituted by the possible rotation of the sections around their longitudinal axis, thus negatively affecting the quality of the bent pieces which are obtained, and causing a possible lack of planarity of the finished products, for example stirrups or shaped products, which may not lie on one plane.
  • the Italian patent No. 1038796 (corresponding to GB 1454738 ), in the name of the company EVG Engineerings U. Verêts Deutschen m.b.H., describes a drawing assembly constituted by at least three misaligned rollers which determine a curved progress pathway. More precisely, two of these rollers, one of which at least is motorized on a fixed axis, are positioned on a side of the said progress pathway, while the third roller, positioned on the other side of the progress pathway, has a floating axis and is elastically pushed by suitable pushing members. According to a particular embodiment, three rollers having fixed axes are positioned on a side of the progress pathway, and on the other side two rollers are fitted floating, so as to determine the said curved progress pathway. The two floating rollers are fitted vertically and coaxial to two corresponding rollers with fixed axis, having a diameter smaller than that of the other rollers, while the third roller with fixed axis is placed in a median position between the two previous couples of rollers.
  • a curved progress pathway for curved-type sections increases the amplitude of the contact surface between the sections in progress and the wheels of the drawing assembly, because it determines a partial winding of the sections on the wheels themselves, respectively along an arc of the curved pathway, with a beneficial effect on the specific pressure thus reduced and on the adhesion in the contact between the wheels and the sections.
  • a further disadvantage lamented in the machines intended for working more than one wire is constituted by the fact that the drawing assembly, in particular if provided with a curved type progress pathway for the sections, may produce a push on the rods engaging the last wheel of the preceding horizontal straightening assembly, thus causing the positioning of the same rods outside the provided groove and in a different way for each of them. This can obviously cause serious irregularity of the straightening.
  • the aim of the present invention is to solve the cited problems, by devising a drawing assembly in machines for working metal sections, which is able to improve in a significant way the adhesion of the drawing wheels and to improve the grip on the sections to be fed without being affected by the difference of the fed diameters and without causing disadvantages in case more wires are worked contemporarily.
  • a further scope of the present invention is to provide for a drawing assembly that is able to reduce the specific pressure exerted on the metal sections in differentiated way, depending on the diameter of the worked rod, so as to avoid possible damages of the sections.
  • a further aim of the present invention is to provide for a drawing assembly with a structure that is simple, safely reliable in operation and highly flexible in use.
  • 1 refers to the drawing assembly intended to be applied in machines for working metal sections.
  • the drawing assembly 1 is positioned in known way downstream of straightening members and preferably in intermediate position between a first assembly of straightening members, lying on a substantially horizontal plane, and a second assembly of straightening members, lying on a substantially vertical plane, not shown in the figures attached. So in the illustrated case a drawing assembly that is downstream of the horizontal straightening assembly and upstream of the vertical straightening assembly is considered, as it often occurs. Obviously the use of any different positioning is not excluded.
  • the drawing assembly 1 comprises a set of drawing wheels suitably motorized and a set of contrasting wheels, substantially positioned on a same vertical plane, fit to determine between them a curved progress pathway P for the metal sections to be fed in the direction designated by the arrow A. More particularly the drawing assembly 1 provides for one or more motorized drawing wheels 2a and lor 2b, preferably fixed, positioned on the lower side of the progress pathway P, and three contrasting wheels 3a, 3b and 3c, preferably movable, positioned on the upper side of the progress pathway P.
  • the drawing wheels 2a, 2b can have different diameter size with regard to the contrasting wheels 3a, 3b and 3c.
  • the contrasting wheels 3a, 3b and 3c are carried by an operating device 4, able to effect the displacement of the same contrasting wheels 3a, 3b and 3c between a lifted opening position ( fig. 2 ) and a lowered position ( figs. 1 , 4 and 5 ) in which these contrasting wheels 3a, 3b and 3c are pressed towards the underlying drawing wheels 2a, 2b.
  • the operating device 4 preferably provides for only one actuator member 5 fitted on a substantially horizontal axis between a couple of arms 6 of levers 9, practically square-shaped and pivoted on pivots 7 to respective abutments 8 rising from the fixed framework 10 of the drawing assembly.
  • the lever 9 are constrained each other by a connecting crosspiece 11 hinged on the pins 12 to the levers 9.
  • the crosspiece 11 and the levers 9 push the stems 14 in order to keep the underlying contrasting wheels 3a, 3b and 3c in position.
  • the axis 13 of the contrasting wheels 3a, 3b and 3c is carried by a prismatic slide 15 that is inserted in a sliding way inside a vertically developed seat 16.
  • the slide 15 is constrained to the stem 14 and is subjected to the opposed action of an elastic member inserted in a suitable hollow 17, practically coaxial to the stem 14.
  • the seat 16 and the hollow 17 are realized in the framework 10 that also carries rotating the drawing wheels 2a, 2b.
  • the opposite closing motion of the actuator member 5 obviously determines the simultaneous lowering of the contrasting wheels 3a, 3b and 3c to the operational position of the drawing assembly 1 (see fig.1 ) and the compression of said springs.
  • the contrasting wheel 3c that is positioned centrally, constrained to the crosspiece 11, performs a larger travel than the side wheels 3a, 3b do, so that in the cited operational position it appears positioned at a height slightly lower than the said side wheels 3a, 3b. On the contrary in the lifted position the contrasting wheels 3a, 3b and 3c appear substantially aligned on the same horizontal plane.
  • At least one of the side contrasting wheels 3a, 3b is fitted rotating on an axis that is not perfectly superimposed with regard to the vertical plane passing through the axis of the underlying wheel and is so displaced in longitudinal direction to the progress pathway P of the sections with regard to the axis of an opposed drawing wheel 2a, 2b it co-operates with, to define this curved progress pathway P.
  • the only contrasting wheel 3b positioned downstream appears displaced along the progress direction of the sections with regard to the axis of the opposed drawing wheel 2b (see figs. 1 and 2 ).
  • the upstream contrasting wheel 3a is vertically aligned to the opposed drawing wheel 2a.
  • the positioning of the contrasting wheel 3b placed downstream of the opposed drawing wheel 2b determines an amplitude increase of the arc of the curved pathway P for which the sections wind on the same drawing wheel 2b, since the sections coming out of the drawing assembly 1 are slightly pushed downwards by the contrasting wheel 3b.
  • This increase of the winding arc produces a further reduction of the specific pressure, so as to avoid the risk of possible damages of the sections.
  • a further advantage is the rise of a yielding effect on the sections, so as, in practise, to perform a preliminary straightening action of the sections on the plane in which they are lying.
  • FIG. 4 a different embodiment of the drawing assembly 1 according to the invention is shown, in which both side contrasting wheels 3a, 3b appear displaced externally with regard to the vertically aligned position as to the opposed drawing wheels 2a, 2b.
  • the upstream contrasting wheel 3a appears displaced upstream along the curved pathway P, that is towards the entry of the drawing assembly 1, while the downstream contrasting wheel 3b is displaced downstream, that is towards the exit of the drawing assembly 1.
  • the drawing assembly according to the invention reaches so the aim of improving the adhesion of the drawing wheels and the grip on the sections to be fed in a significant way, reducing as well the specific pressure exerted on the metal sections, so as to avoid possible damages of the sections.
  • This is obtained thanks to the displacement along the longitudinal direction of only one or both of the side contrasting 3a, 3b with regard to the vertical lying plane of the axes of the opposed drawing wheels 2a, 2b they cooperate with to define the curved progress pathway P, so as to proportionally increase the winding arc of the sections on the said drawing wheels 2a, 2b, together with the action exerted by the central contrasting wheel 3c.
  • a device 20 adjusting the lowering travel imposed to the central contrasting wheel 3c by the interposition of differentiated shims is illustrated in the figs. 6, 7 and 8 .
  • the adjustment device 20 provides for a body 21 fitted in a suitable housing realized in the crosspiece 11, in the coupling seat 19 for the stem 14.
  • the body 21 carries, on a support frame 22 extended transversally with regard to the crosspiece 11, a linear actuator member 23 able to set the shim 24 in motion. This shim 24 fits in above the seat 19 so as to displace the stem 14 more downwards.
