摘要： One aspect of the present disclosure is a manufacturing device for a bent pipe by which the bent pipe is obtained by bending a double pipe. The manufacturing device for a bent pipe includes an inner core metal, an intermediate core metal, a bending mold, and a controller. The controller executes a first bending process, a second bending process, and a re-bending process. In the first bending process, a first pipe and a second pipe are bend in a first direction in a first area. In the second bending process, the first pipe and the second pipe are bent in a second direction in a second area. The second area has more distance from a coupling portion than the first area does. In the re-bending process, the second pipe is bent in the same direction as the second direction in the second area.

摘要： A system for manufacturing hollow tubular jewellery comprises a die and core assembly for extruding a hollow metallic tube, wherein a core is positioned within a die of the die and core assembly to define three-dimensional surfaces or curved surfaces of a hollow metallic tube. A mandrel is provided for bending the hollow metallic tube, wherein the mandrel is fixed proximal from the die and core assembly. A laser source is provided, which is configured to emit a laser beam to form perforations on the hollow metallic tube. The system includes a fixture which is adapted to hold the hollow metallic tube. The fixture is configured to rotate and tilt to adjustably position a three-dimensional surface or curved surface of the hollow metallic tube perpendicular to the laser beam for forming perforations.

摘要： A manufacturing method for a bent member of the present invention includes a holding step of holding one end portion of a long steel material having an opening end in a longitudinal direction by a chuck, a feeding step of feeding the steel material in the longitudinal direction with the one end portion as a head after the holding step, a heating step of performing high-frequency induction heating on a portion of the steel material in the longitudinal direction to form a heated portion, a bending step of moving the chuck in a three-dimensional direction to apply a bending moment to the heated portion, and a cooling step of injecting a cooling medium to the heated portion to cool the heated portion after the bending step. When the heating step is started, the chuck is cooled by the cooling medium in a state where a heating amount applied to the one end portion when the heated portion is formed on the one end portion is greater than that of an upstream side adjacent portion adjacent to the upstream side of the one end portion as seen along a feeding direction of the steel material.

摘要： In straightening a tube using a roll straightening machine provided with drum type straightening roll pairs vertically opposingly disposed, at least an outer layer portion of a roll main body is made of elastic material having spring type hardness Hs (JIS K 6301 A type) of 50 to 100 in at least three pairs of straightening rolls on an outlet side of the roll straightening machine, and an offset amount is imparted to a tube engaged in the three pairs, at least, of straightening opposing rolls such that η defined by an equation (1) ranges from 1.0×10−3 to 1.5×10−3. The offset amount is set at each of three positions along a tube axis where the upper and lower rolls of each pair horizontally cross. Therefore, an S/N ratio can be enhanced in an eddy current test from inside of the tube to improve inspection efficiency, and excellent quality accuracy can be ensured in a heat transfer tube used in a steam generator and the like. [ Formula   1 ] η = 1 R × ( d 2 ) ( 1 ) where a relationship of R=(δ2+L2)/2δ holds, assuming that d (mm) is a tube outside diameter, L (mm) is a roll stand span of the roll straightening machine, and δ (mm) is an offset amount.

摘要： Disclosed is a device for bending open, half-open, and closed hollow profiled members (11′). Said bending device operates with a central roller (3) that rests against the inner surface of the bent profiled member, a milling roller (4) which leans on the outer surface of the bend, and a bending roller (11) located at the discharge end of the profiled member. Said bending roller (11) acts upon the outer surface of the bend, counter to the supporting effect of a support roller (5, 6) that rests against the outer surface of the bend at the feeding end. In order to allow also thin-walled, sensitive profiled members to be shaped, additional milling rollers (12, 13) that act upon the top and bottom sidewall of the profiled member are disposed on a plane extending perpendicular to the bending plane in relation to the opposite central rollers and milling rollers (3, 4).

摘要： A cold-formed, raised-center axle for a heavy-duty vehicle includes a central tube having a pair of ends, a pair of spindles attached to the central tube ends, and a wall thickness of from about 0.500 to about 0.625 inches. A hump is formed in the center portion of the tube and includes compressive residual stresses in its bottom portion when the axle is in an in-service position. A method for forming the raised-center axle includes the steps of providing a substantially straight axle, inserting the axle into a press, over-forming a hump in the axle in the direction such that camber is induced in the axle, and forming the axle in a second direction, thereby substantially removing the camber and replacing a detrimental residual stress state in the humped portion of the axle with a beneficial residual stress state.
