Abstract

1325377 Making branched tubes; fluid inflation; shearing NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 8 Dec 1970 [17 Dec 1969] 58213/70 Headings B3A B3Q and B3W A device for making a branch to a tube 1 comprises a pair of die halves 2 with clamping inserts 3 to grip the tube and a die part 6 slid. able in a slot in the upper die half to define a cavity 4 for the branch and to co-operate with internal tube clamps 18 on a mandrel 10 so that when the mandrel is pulled the die part 6 is moved to define the cavity. The mandrel 10 has a fixed seal ring 12 and a movable seal ring 13. The clamps 18 comprise two sets of segment jaws connected by rods 17 to the movable seal ring 13. Fluid pressure is supplied through a bore 11 to move the seal ring 13 which pulls the jaws up the inclines 19 to clamp the tube to the die part 6. The mandrel is pulled in the direction 9 and the bulge produced between the fixed clamping inserts 3 and the die part 6, is forced by the fluid into the cavity. A pressure plug 7 limits the expansion. The plug is replaced by a shearing adjunct, Fig. 4 (not shown), with an annular blade (32) to remove the end of the branch. Several branches may be formed successively along the tube.
