Abstract

759,146. Making tube fittings. HUET, A. March 19, 1953 [June 30, 1952], No. 7611/53. Classes 83 (2) and 83 (4). Flanging.-Apparatus for producing nipples or branch openings b on large diameter tubes a comprises an internal punch c for piercing the tube wall and an external die d for shaping the outside of the nipple, which die carries a counterpunch e for engaging the internal punch and releasing it from the wall. The internal punch is operated by a telescopic ram h, i, movable in a cylinder g by hydraulic or pneumatic fluid admitted through a duct k. The cylinder g is supported in the tube by feet f. The external die is operated by pistons n through a linkage m. The counter-punch e may alternatively be operated independently of the die and may be slidably mounted therein. Specification 754,431 is referred to.
