摘要： PURPOSE:To efficiently manufacture the title dissimilar metallic pipe joint with different inside and outside dia. by enlarging or reducing the dia. of a double clad pipe from a pipe end to the optional position and forming the double clad pipe with the different dia. and cutting and removing inner layer material of the small dia. part side and outer layer material of the large dia. part side, etc., of the pipe. CONSTITUTION:The double clad pipe and a double clad rod are cut out to the prescribed length and the dias. thereof are enlarged or reduced from one ends up to the optional positions thereof. In dia. enlarging work, in case of the double clad pipe 3, a plug 4 is inserted into the inner layer material 1 and the outer layer material 2 and pushed-in up to the middle thereof. In case of the double clad rod, a wedge-shaped plug is pushed-in up to the middle thereof. In dia. reducing work, the double clad pipe 3 is pushed in a die 5 up to the middle thereof. The prescribed parts of the inner layer material and the outer layer material are then machined and removed and the straight pipe type dissimilar metallic pipe joint consisting of the inner layer material at the one end side and the outer layer material at the other end side and having the same inside and outside dia. extending over the joint entire length or the different dia. type dissimilar metallic pipe joint having the different inside and outside dia. from the joint central part is formed. By this method, the dissimilar metallic pipe joint is manufactured efficiently.

摘要： PURPOSE:To obtain a bomb of high accuracy in its high yield and low cost by forming a hollow by the cold pre-rear part extrusion of a blank, forming a bottomed pipe by a cold rear part extrusion by placing a solid lubricant in the hollow and drawing by a hot treatment the opening end only by the die for necking of high temp. CONSTITUTION:A pre-rear part extrusion is executed on an Al or Al alloy blank 1 to form a hollow 1a on the end face of the blank 1. A solid lubricant 2 is placed on the hollow 1a to obtain a bottomed pipe 3 by cold rear part extruding. A mouthpiece part is then formed by one time forward extrusion by sticking a lubricant after heating by using the die 4 for necking. An Al or Al alloy made gas bomb can thus be obtd. at low cost and with high accuracy.

摘要： PURPOSE:To curtail a cutting stage and to improve working effieiency by parting a formed article which is formed by winding spirally a long-sized blank pipe on a mandrel having a prescribed outside diameter, to a prescribed circumferential length then straightening the same. CONSTITUTION:The top end of a blank pipe P delivered from a guide device 2 is pressed and fixed toward a mandrel 11 by a pawl part 14, and the device 2 inclined to have a pitch anglebeta, then a block 13 is rotated. The device 2 is moved at the same instant in the direction parting from a block 12 in such a way that the pitch at each one revolution of the mandrel 11 is delta, thus winding spirally the pipe P on the outside circumference of the mandrel 11. The pipe P is cut on the outlet side of the device 2 upon ending of winding and is removed from the mandrel 11 by releasing the pressing by a pawl part 14. The resulting semiprocessed product C is parted to a prescribed circumferential length to obtain a bent product M, which is positioned in the groove parts of dies 41, 41 of a setting tool 4, then the dies 41, 41 are pressed to set the twist and flattening of the product M.

摘要： PURPOSE:To save expenses for tools, and to reduce the number of man-hours, by forming a steel plate to a U-shaped formed article and after that, bulging a part to be formed, bend-working a straight wall part, and weld-joining it. CONSTITUTION:A blank steel plate 5 is subjected to pressing and a semi-finished product 6 consisting of a curved surface bottom part 1' curved by the same curvature as a product base pipe part 1, a branch pipe part 2 formed in the center of the curved surface bottom part 1', and the remaining straight wall part 1'' is manufactured. Subsequently, the second semi-finished product 16 is obtained by bending the straight wall part 1'' to the same curvature as the product base pipe part 1. Straight side edges 4', 4' opposed to each other, of this semi-finished product 16 are butt-welded. In the end, both pipe ends of the base pipe part 1 and the pipe end of the branch pipe part 2, of the second semi- finished product 16 are put in order by cutting as necessary, and after that, a product is obtained by groove working.
