Definitions

  • the forming is done using one or more sets of discs which force the tube against an internal mandrel pin which has a work surface with a constant diameter which is less than the I.D. of the starting tube.
  • the amount of work-hardening present in each portion of the work piece will vary widely. For example, there will be areas of high work-hardening near the outer diameter of the fin, with relatively low work-hardening effect in the tube wall under the fin. If one then assumes that the areas of highest work-hardening, which are produced near the outer diameter of the fin, are the maximum achievable prior to failure, one may conclude that this configuration limits the fin dimensions which are possible without use of hot working, heat treatment, and/or metal removal procedures.
  • a tube indicated generally at 11 is shown in working relationship with respect to a mandrel holding rod 12 having a first larger ⁇ diameter mandrel section 14 and a second smaller diameter mandrel section 16 held thereon by a fastening member 18.
  • a plurality of finning arbors 24 are located circumferentially around the tube (11) on skewed axes in the usual fashion, although only one such is shown in Figure 1.
  • the arbors 24 are each provided with spaced sets 26 and 28 of finning discs which are separated by a spacer member 30 and retained on the arbor by fastener means such as a cup washer 32 and socket head screw 34.
