Abstract
807,608. Making tubular fittings; stamping. HUET, A. Aug. 2, 1957 [Oct. 18, 1966], No. 24634/57. Classes 83 (2) and 83 (4). A method of producing tubulures along a generatrix of a header by compressing the wall of the header between a punch mounted on a supporting bar positioned inside the header and a die applied externally to the wall of the header, the wall having been previously heated and, if necessary, pierced at the places where it is desired to form the tubulures, is characterized in that for the purpose of producing a series of tubulures simultaneously, the bar d introduced into the interior of the header tube a comprises a complete series of punches e and a shell f conforming to the outside of the wall of the header comprises as many dies g as there are punches e. The header is arranged on a supporting base c and the bar d is positioned inside the header. After heating the header along the generatrix A-A and applying the shell f, the bar d is displaced in the direction of the arrow C to form the tubulures h (Fig. 2). The punches are disengaged from the tubulures either by raising the base c whilst holding the bar stationary or by lowering a rod i carrying counter-punches i<SP>1</SP>.
