Definitions

  • the invention relates to a method for local forming of a hollow profile where a forming tool interacts with an induction coil.
  • the tool concept consisting of a stamp and a backing tool, often demands a time consuming and expensive fabrication of necessary tools.
  • the relatively complex tools may also lead to poor reliability in production or high maintenance costs.
  • Such deviation may e.g. represent a problem in assembly or joining processes such as welding, brazing, bonding, riveting or other mechanical joining methods, which usually require a good fit up of the parts to be joined.
  • the calibration operation generates waste material.
  • Calibration using cold forming is associated with a relatively high degree of elastic spring back of the work piece. Due to the elastic spring back, small geometrical corrections will be difficult to perform. Variations in the spring back e.g. due to inconsistent mechanical properties or geometrical dimensions, will cause deviations in the final geometry of the work piece.
  • the US 4,532,793 discloses a method for local forming of a sheet metal where a force is applied to a forming tool for forming a part of said sheet and where a predefined local area of the sheet is heated to a temperature where the yield stress of the material in the said area is substantially lower than the yield stress of the surrounding colder material by an induction coil and that this heated area is formed by pressing the forming tool into the heated area while the surrounding colder material of the sheet is maintained substantially unaffected of the forming operation.
  • the present invention as defined by claim 1 or 2 represents a flexible method for fabrication of e.g. local protrusions or imprints.
  • the principles also enable a higher degree of forming of the work piece and can be performed preferably without any backing tool, thereby enabling processing in regions of the work piece where the access of a backing tool is limited.
  • the method furthermore improves the flexibility of the geometry due to the ability of obtaining small bending radii or sharp edges on the protrusions or imprints.
  • the relative simple, low cost apparatus also decrease the possibility of failure during production, thereby reducing maintenance costs, increasing the up time of the production and reducing the scrap rate.
  • the method furthermore enables the calibration of end sections without any cutting operations.
  • the present invention utilises the temperature dependency of the mechanical properties of the material. This spatial variation of mechanical properties across the work piece is utilised to allow forming within a locally heated region without distorting the surrounding material, which has a higher resistance to forming.
  • the present invention may for some applications, utilise the thermal field as a virtual die for defining the regions of plastic flow and hence the final shape.
  • the localised heating can be manipulated to form a sufficiently sharp boundary between the soft and hot material that easily forms plastically and the adjacent material at lower temperature, which has a higher resistance to forming.
  • the rapid local heating is done. by an induction coil, which is situated in the neighbourhood or on the surface of the work piece. Material in close proximity of the coil will be heated until a temperature is reached where the yield stress of the material is substantially lower than the surrounding material.
  • the forming operation takes place in material with an essentially non-uniform temperature distribution.
  • the surrounding material have higher strength, the difference in material strength will enable the surrounding material to maintain its original shape.
  • this technique does not take advantage of the possibility of forming parts of the sheet in a heated mode.
  • the heating procedure is used as a material property treatment aiming to change the room temperature properties within a localised area of the profile. Even though this method changes the room temperature formability of the material, the benefit of the process is substantially lower than for forming in a partially hot state.
  • the present invention is based on forming of a localised hot area of the work piece, thereby taking advantage of the extended softening of the heated material and the increased difference in material strength between the hot region and the surrounding cooler material. Furthermore the invention requires simpler and cheaper tooling compared to conventional forming. It also requires very low loads for forming, which reduce the investment cost as well as the complexity of the production equipment. In addition, the geometric accuracy of the components and parts fabricated by the method is high due to limited elastic strain as a consequence of the low yield stress at elevated temperature. Normally, the forming is done without use of any lubricants. Another benefit is obtained during the forming since most metallic materials exhibits reduced anisotropy at elevated temperatures, but this depends on the initial texture as obtained from the preceding thermo mechanical process route.
  • a further benefit of the invention is the possibility to control the mechanical properties in the protrusion or imprint.
  • the work hardening is reduced, thereby ensuring an even better ductility in the formed regions. This is especially advantageous in regions with sharp forming radii which often experience large strains in e.g. impact absorbing members.
  • the method can be used to any local reshaping of a hollow profile and is especially suitable for local forming in thin walled open or closed profiles such as extruded or rolled hollow profiles.
  • Typical applications include automotive structures such as bumpers, crash boxes, engine cradles and other frame structures.
  • the method can be used on any material being affected by a heat treatment, such as aluminium alloys, other metals such as steel, magnesium and alloys of these, polymers and the like.
  • the method can also be used to make imprints or protrusions on already formed imprints or protrusions.
