Definitions

  • the invention relates to a method for manufacturing a metal tubular blank suitable for forming into a product.
  • the invention further relates to a tubular blank and a product produced from such a tubular blank.
  • a tubular blank is usually produced from a planar blank, which is cut from a metal sheet. This planar blank is formed into a tube which is then laser welded to form the tubular blank. In a typical hydroforming operation a tube, or a tubular blank, is bent into the overall shape desired for the final part, and then placed between a pair of dies.
  • the dies provide a cavity around the tube or tubular blank which has an interior shape matching the exterior shape desired for the part. Then, the ends of the tube or tubular blank are sealed and it is internally pressurised to expand it into the shape of the dies' cavity.
  • means to influence the friction between the tube or tubular blank and the forming tools are often used. These means may for instance comprise in-line lubrication stations in the hydroforming line. Friction influencing means may also be applied manually. These types of friction influencing means are complicated and/or expensive.
  • one or more of the objects are reached by a method for manufacturing a metal tubular blank suitable for forming into a product comprising the steps of
  • the tubular blank is already provided with a layer with a friction influencing function prior to entering the forming line. Consequently there is no need to apply means with a friction influencing function, such as a lubricant, in the forming line, making in-line stations or manual application of means with a friction influencing function obsolete.
  • the method according to the invention also enables to apply the means with a friction influencing function in a controlled manner thereby making the application of the means more reproducible, and thereby also making the behaviour of the tubular blank during forming more reproducible. This increases the stability and reproducibility of the forming process and results in a more reproducible formed product.
  • first and/or second layer with a friction influencing function in the form of a foil, a dry lubricant, a wax or an oil, a very controlled and reproducible application is obtained.
  • the planar blank is produced from a coil and the first and/or second layer with a friction influencing function is applied to the coil prior to producing the planar blank.
  • the first and/or second layer with a friction influencing function may have been applied to the coil immediately prior to forming of the planar blank, i.e. between decoiling and blanking, but it may also have been applied prior to coiling of the coil.
  • the advantage of this embodiment is that the first and/or second layer with a friction influencing function is applied to a large surface, thereby facilitating quality control and reproducible application of the layer or layers. This embodiment also enables to produce planar blanks and hence tubular blanks at a lower cost.
  • the foil is a hydrocarbon such as polyethylene or a fluorocarbon such as polytetrafluorethylene.
  • This type of layer with a friction influencing function functions as a lubricant.
  • the foil enables easy application to the coil or the planar blank, for instance by known methods such as laminating or coextrusion of the foil, whereas it provides excellent adhesion to the planar blank prior to or during forming of the tubular blank and also during storage, handling and forming of the tubular blank.
  • the blank is essentially quadrangular, such as essentially rectangular or essentially tapered.
  • This type of lubricated blank will result in an essentially cylindrical tubular blank or an essentially conical tubular blank. The latter facilitates forming sloping shapes in the formed product.
  • the planar blank comprises at least a first blank portion and a second blank portion and wherein the first blank portion has different geometrical dimensions than the second blank portion and/or wherein the first blank portion is made from a different material than the second blank portion and/or wherein the material of the first blank portion has different properties than the material of the second blank portion.
  • planar blanks comprising a plurality of blank portions, i.e. at least two, can be produced by joining together a corresponding number of planar blank portions, each produced from metal sheet, by means of a joining technique such as welding for example laser-welding.
  • This embodiment enables to choose the geometry, for instance the thickness of the blank portion, or the type of material, or the properties of the material, independently of the geometry, the type of material, or the properties of the material of the second blank portion.
  • the strength of the first blank portion may be chosen differently from that of the second blank portion because of local strength requirements in the final formed product.
  • material for the first blank portion having different resistance to corrosion than the material of the second blank portion because of local requirements for corrosion resistance in the final formed product.
  • the invention also encompasses tubular blanks made from planar blanks having more than two blank portions, which blank portions may all have different characteristics.
  • the aim of at least one of the layers with a friction influencing function is to decrease the friction between the tubular blank and the forming tools which can be used to form the tubular blank into a product. Decreasing the friction facilitates forming the tubular blank into a product. It may also reduce the forces required to form the tubular blank into a product during the forming process.
  • at least the function of the second layer with a friction influencing factor is to decrease the friction between the tubular blank and the forming tools which can be used to form the tubular blank into a product.
  • the second layer being on the outer surface of the tubular blank, is likely to benefit from a reduced friction in terms of reducing the process forces during forming, but also in terms of a reduced wear of the outer surface and the forming tools.
  • the tubular blank manufactured as described hereinabove, is formed into a product at least partly by hydroforming.
  • the tailored friction on the inside and/or the outside provides a hydroformed product with the required surface, dimensions and properties.
  • a tubular blank is provided which is obtained using the method in accordance with any one of the methods described hereinabove.
  • a product obtained by hydroforming a tubular blank which tubular blank is obtained using any one of the methods described hereinabove.
  • a tubular blank may be produced from a planar blank produced from a metal sheet such as a steel with a thickness of about 1.3 mm, which is provided with a first layer with a first friction influencing function on the first side of the planar blank and a second layer with a second friction influencing function is applied to the second side of the planar blank prior to forming the planar blank into a tubular blank.
  • the friction influencing function is chosen so as to reduce the friction on the second surface (i.e. the outside of the tubular blank) and to increase the friction on the first surface (i.e. the inside of the tubular blank), so as to influence the friction between the tubular blank and forming tools which can be used to form the tubular blank into the product.
  • the increased friction on the inside of the tubular blank provides a firm grip of the bending rod to the tubular blank, whereas the reduced friction on the outside of the tubular blank provides a smooth surface.
  • bending requires low friction on the inside of the tube.
  • High friction levels on the outside may be beneficial for obtaining more grip during bending.
  • the nature of the friction influencing layer may be chosen so as to obtain the required friction properties during processing of the tubular blank.
  • a tubular blank may be produced from a planar blank, which is provided with a layer with a friction influencing function on the second side of the planar blank prior to forming the planar blank into a tubular blank.
  • the friction influencing function is chosen so as to reduce the friction on the second surface (i.e. the outside of the tubular blank) so as to influence the friction between the tubular blank and the hydroforming tools used to form the tubular blank into the hydroformed product.
  • the reduced friction on the outside of the tubular blank provides a smooth surface whilst also limiting the process forces.
  • a tubular blank may be produced from a planar blank, wherein the planar blank has a plurality of blank portions.
  • a planar blank may comprise three blank portions, such as a first blank portion of 2 mm aluminium with a proof stress of 150 MPa, a second blank portion comprising a 1 mm high strength low alloy steel with a tensile strength of above 600 MPa and a third blank portion comprising an 1.5 mm austenitic stainless steel with excellent corrosion resistance.
  • the tubular blank, and the final product which is made from it, is provided with a layer of friction influencing function which is applied to the second surface of the planar blank comprising a plurality of blank portions, and which function is chosen so as to reduce the friction.
  • a layer of friction influencing function which is applied to the second surface of the planar blank comprising a plurality of blank portions, and which function is chosen so as to reduce the friction.
  • a tubular blank may be produced from a planar blank, which is provided on its second surface with a first layer with a first friction influencing function on part of the first side and with another layer with a another friction influencing function on at least part of the second surface wherein the two layers each with their respective friction influencing function may at least partly overlap.
  • the layer or layers with the friction influencing function can be used to increase the friction in certain areas of the tubular blank, thus enabling a controlled material flow, which could be beneficial to reduce or increase strain levels in certain areas of the product.
