Abstract

909,986. Stamping; tube expanders. OLIN MATHIESON CHEMICAL CORPORATION. March 1, 1961 [March 17, 1960], No. 7498/61. Class 83 (4). A method of mechanically distending a tubular passageway of a metal tube sheet formed by selectively welding superimposed metal sheets 2, 3, e.g. of aluminium, having different elastic limits to define a pattern of unjoined portions 5 which are to be expanded to form tubular passageways is characterized by inserting between said unjoined portions a mandrel having a first bearing surface 14 opposite the unjoined portion of the sheet having the lower elastic limit and an oppositely disposed second bearing surface 13 opposite the unjoined portion of the sheet having the higher elastic limit wherein the ratio of the area of the bearing surfaces is equal to the inverse ratio of the said elastic limits times the ratio of the amount of distention desired in each unjoined portion times the ratio of the thicknesses of the unjoined portions. The mandrel has a point 15 to initiate the separation of the unjoined portion after which the mandrel is manually or otherwise forced into the passageway 9, as shown in Fig. 5. In another embodiment for sizing a partially or fully-formed tubular passageway 18, Figs. 6 and 7, a sizing tool 22 having working portions 23, 24 and 25 is used. In a further embodiment for expanding and sizing a passageway 33 provided with a restriction 32 a tool 34 having working portions 35 and 36, Figs. 11 and 12, is used to expand the passageway and the restriction. Specifications 759,804 and 796,229 are referred to.
