Definitions

  • the present invention relates to a method for optimising a process for extrusion of an aluminium section.
  • the method according to the present invention was developed relative to the production of panels for industrial vehicle bodies, in particular hollow panels having one or more tubular segments.
  • aluminium sections are extruded by forcing the aluminium in the plastic state through a die which gives it the required shape.
  • the overall cost per unit of length of a section is given by the sum of a fixed cost substantially linked to the existence of the production company with the relative extrusion plant, and a variable cost given by the quantity of material which constitutes the section (therefore, substantially the weight per unit of length).
  • variable cost Whilst the fixed cost per unit of length of the section produced falls as the productivity of the plant increases, the variable cost, again per unit of length produced, falls as the weight per unit of length of the section falls.
  • the surface of the product obtained at the end of the extrusion process shows signs of deterioration following the appearance of scratches and/or scoring and/or lacerations and/or deformations and/or undulations which are more or less extensive and/or the extruding die may even be broken.
  • the limit speed which, as indicated, is determined by friction, depends, all other extrusion plant factors being equal, on the thickness of the section. As the thickness of the section is reduced, the limit speed is also reduced.
  • the limit speed is substantially set by the thickness of the section to be obtained.
  • the limit speed is determined by the thickness of the portion of the section with the minimum thickness.
  • the present invention is a result of the discovery that, for many applications, the limit thickness determined based on the minimum cost of the section to be produced is greater than that which would be sufficient to guarantee the mechanical strength required in the end use of the section.
  • the technical need of the present invention is to perfect a method for optimising a process for extrusion of an aluminium section which allows extrusion, at least at the same speed as the current plants, of sections with a weight (for the same unit of length) lower than the methods of extrusion currently known and/or which at least allows an increase in the speed of extrusion if the weight is the same per unit of length.
  • Another technical need of the present invention is to perfect a method for optimising a process for extrusion of an aluminium section in which the reduction in the overall weight per unit of length is achieved by reducing the thickness of the section currently considered the minimum with current extrusion methods.
  • a further technical need of the present invention is to perfect a method for optimising a process for extrusion of an aluminium section in which the reduction in the overall weight per unit of length is achieved by reducing the minimum thickness of the section to be produced but substantially maintaining and/or improving the resistance to bending of the section, in particular if it is to be used for example as a panel for industrial vehicle bodies with one or more tubular segments.
  • the numeral 1 denotes as a whole an optimised aluminium section obtained with an extrusion method optimised according to several non-limiting embodiments of the present invention.
  • the optimised section 1 consists of a panel for an industrial vehicle body, but this is only an example of application of the optimisation method disclosed, which may, in general, be used for the production of any type of section.
  • the extrusion process in general involves, in the known way, the section to be produced being obtained by extrusion through a die with a predetermined shape.
  • the present invention relates to the optimisation of an extrusion process which, each time may be used for the production of any type of optimised section 1 designed for the purpose or, as a non-limiting example, the one illustrated in Figure 2 deriving from a non-optimised section (as a non-limiting example, the one illustrated in Figure 1).
  • the (non-optimised) section will have a reference weight per unit of length PR1, at least a portion with practically uniform minimum thickness SM1, used as the basis for calculation, for the extrusion process, of an extrusion limit speed VL1 corresponding to the maximum extrusion speed which can be achieved without section surface deterioration, which generally occurs at the portion with the minimum thickness (which is the critical portion).
  • extrusion is performed in such a way that the optimised section 1 has, in cross-section, at least at its portion which in the case of a non-optimised section is the one with the minimum thickness SM1, alternating zones 2 with thickness less than the minimum thickness SM1, and zones 3 with thickness greater than that of said zones 2.
  • zones 2, 3 may be achieved either only at the portion with minimum thickness, or at some or all of the other portions of the section 1.
  • zones 2, 3 may be easily achieved by preparing a suitable die.
  • the zones 3 constitute, during extrusion, outlets for the aluminium which allow the zones 2 adjacent to them to be obtained without surface deterioration.
  • a section 1 obtained according to the present invention will be indicated as an optimised section 1, or more simply as a section 1, whilst a section obtained using the non-optimised process will be indicated as a non-optimised section.
  • an extrusion limit speed VL2 can be identified, corresponding to the maximum extrusion speed that can be reached without surface deterioration of the section 1 obtained according to the above description.
  • the extrusion limit speed VL2 will be equal to the extrusion limit speed VL1 defined for the non-optimised section, if the weight per unit of length PR2 of the optimised section 1 is lower than the weight per unit of length or reference weight PR1 of the non-optimised section, whilst it will be greater than the limit speed VL1 if the weight per unit of length PR2 of the optimised section 1 is greater than the reference weight PR1 of the non-optimised section.
  • the optimised section 1 will have a weight per unit of length PR2 non greater than the weight for the same unit of length PR1 of the non-optimised section.
  • H1 may have any value even if the best results are obtained with H1 greater than H.
  • Figure 6 also shows, with a dashed line, a thickness H3 corresponding to the average thickness of the optimised portion illustrated.
  • This thickness H3 corresponds to the theoretical average thickness that the optimised section 1 would have if it had a constant thickness, the same volume and the same weight for the same unit of length.
  • Figures 2 to 6 illustrate some of the many possible embodiments of the present invention.
  • the alternation of zones 2, 3 is obtained on most of the section 1, whilst in the non-optimised embodiment, the non-optimised section has a thickness that is practically constant all over.
  • the present invention may be applied both to solid sections (without tubular cavities), and to hollow sections, as is the case for panels for vehicle bodies, with one or more tubular segments.
  • the optimisation method disclosed may be applied only when the section 1 optimised or to be optimised has, at least at a portion with the limit thickness, at least one surface (visible or hidden because it is inside, as in the case of the panels illustrated in Figures 2 to 5) which can be produced in accordance with the present invention, without conditioning the subsequent use of the optimised section 1.
  • a technician in the field will be able to define, with simple tests, the most suitable configuration and alternation of the zones 2, 3, for the best optimisation of the extrusion process.
  • a technician in the field can also immediately check whether or not, once a section has been produced according to the optimisation method described above, the latter really constitutes an optimisation, even when he does not know the limit speed VL1 and the limit thickness SM1 of the non-optimised products.
  • the present invention brings important advantages.
  • a method for optimising a process for extrusion of an aluminium section 1 has been perfected, which allows extrusion, at the same speed as current plants, of sections with a lower weight for the same unit of length compared with the extrusion methods currently known, with a consequent economic saving in terms of the cost of the material.
  • the extrusion speed can be increased with the same weight per unit of length or an ideal compromise can be reached between weight and extrusion speed.
  • the section 1 has, at the zones 3, a thickness H1 equal to or greater than the thickness H of an equivalent non-optimised section.
  • the zones 3 form a kind of ribbing for the section 1, guaranteeing the optimised section 1 a mechanical strength substantially equal to (if the thickness of H1 is equal to H) or greater than (when the thickness of H1 is greater than H) the non-optimised sections.
  • the advantage just described is particularly appreciable in the production of hollow sections, with one or more tubular segments, for example such as those of panels for vehicles bodies with the optimisation disclosed applied in the cavities in the section 1, therefore, in a zone that is not visible during use of the finished product.
  • the present invention for the production of sections with low thickness allows a reduction in the pressure which acts on the die by improving the flow of aluminium through the die thanks to the presence of the zones 3, significantly reducing the risk of the die breaking compared with the current extrusion methods.
