Definitions

  • the invention may include the further step of forming the tubular work piece to a conical shape before flattening.
  • the formation of a relatively short tubular work piece to a conical shape is a relatively simple operation and can be achieved by any one of a number of known and inexpensive techniques. This invention avoids the need for forming an elongate member to a conical shape, which requires expensive techniques.
  • FIG. 3 is a diagrammatic representation of the stage of advancing the flattened member in the direction of its longitudinal axis to extend its length and reduce its wall thickness
  • the ribbon like flat tube cut from the roll is then positioned within the cavity with its ends projecting therefrom, and an upper tool portion 37 is positioned over the retaining tool 32, the upper tool portion 37 having depending flanges 38 which engage the side walls of retaining tool 32 so as to reduce outward movement thereof when fluid is applied at pressure to the flattened tube contained within the cavity.
  • the conical shaped member 51 is then passed between flattening rollers 55 (after annealing if this is necessary), the flattened member so formed is annealed, and re-rolled between the rollers 55 (set closer together) to form the elongate flattened member 56 wherein again the length is increased substantially and the width only to a small degree by the rolling operation.
  • the flattened member 56 then has one end closed by welding, crimping or the like and the other end flared to form a conical opening 29 as in the first embodiment.
  • the flattened member is placed within a retaining tool 59 of U section, and the retaining tool 59 has an upper tool portion 60 positioned over it.
  • the hollow closure member 40 of similar formation to that described in the first example is inserted in the conical opening 29 of the flattened member and again fluid at pressure is pumped into the flattened member to deform the contiguous walls away from one another.
