摘要： Tube forming methods can be used for efficient transition in the production of tubes having varying thickness. Material used to form consecutive tubes may have the same thickness along a separation plane separating a first discrete section from a second discrete section of the material, and the first discrete section and the second discrete section may each have varying thickness in a feed direction of the material. With such a thickness profile, the first discrete section of the material may be formed into a first cylinder having varying thickness and separated from the second discrete portion as the second discrete section is formed into a second cylinder having varying thickness. In particular, the transition between the first cylinder and the second cylinder may be achieved without scrap and/or interruption, resulting in cost-savings and improvements in production throughput associated with forming tubes having varying thickness.

摘要： A method for the calibration or end sizing of a hollow profile component produced by extrusion for automobile manufacturing. The hollow profile component is inserted into the cavity of an opened press tool and closing the press tool. Expandable mandrels are introduced into the open profile ends of the hollow profile component. The hollow profile component is calibrated or end-sized by applying force simultaneously on the outside and on the inside. The expandable mandrels are retracted, opening of the press tool, and removing of the hollow profile component.

摘要： Sensor for high-pressure line and method for manufacturing thereof. The sensor detects parameters or properties of fluid conducted in a high-pressure line while maintaining the high pressure of the fluid. The sensor includes an inner tube extending concentrically in the outer tube that together form a tube and at least one groove which extends in the inner surface of the outer tube or in the outer surface of the inner tube in a longitudinal direction, at least one signal line arranged in the groove, and at least one pick-up element connected to the signal line and arranged at least in the groove or in at least one recess which is provided at least in the outer surface of the inner tube or in the inner surface of the outer tube in addition to the at least one groove. The outer tube is in frictional connection with the inner tube.

摘要： A method of manufacturing a tube is provided. The method includes: selecting a core pipe having a thickness that is initially less than a desired thickness of the tube; and building-up an outer layer over an exterior surface of the core pipe via additive manufacturing so as to increase the thickness of the core pipe such that the thickness of the core pipe is equal to the desired thickness of the tube.

摘要： Method for manufacturing a tube of metal in which sensors are attached to tubes, which register and signal a damage of the tube. It is detrimental that protection of the sensors at these tubes against environmental influences is complex. In contrast, it is an object of the present disclosure to provide a method for manufacturing a tube, in which the signal line can be protectively mounted. To solve this object, a method for manufacturing a tube of metal is suggested with an outer tube and an inner tube, wherein a groove is drawn in an inner surface of the outer tube or in an outer surface of the inner tube and subsequently the inner tube and the outer tube are drawn together through a drawing die, wherein the inner dimension of the outer tube is reduced such that after the drawing the outer tube is force-fitted onto the inner tube.

摘要： A method of manufacturing a flaring-processed metal pipe from a hollow shell including a plurality of portions having different deformation resistances in a circumferential direction is provided, the method includes: among the plurality of portions, specifying a portion having a relatively small deformation resistance as a low deformation resistance section, and a portion having a relatively large deformation resistance as a high deformation resistance section; and press-fitting a pipe expansion punch into the hollow shell such that a thickness reduction rate of the low deformation resistance section is smaller than a thickness reduction rate of the high deformation resistance section.

摘要： A method and apparatus for producing a curved tubular segment includes obtaining a curved external tubular element and a curved internal tubular element. The curved internal tubular element is made of a material having a resistance to wear greater than that of the curved external tubular element and has a cross section such as to cover at least part of the internal surface of the curved external tubular element. The curved internal tubular element is inserted inside the curved external tubular element after heating the latter by a heating unit. To form the curved external tubular element on the exact geometry of the curved internal tubular element, a molding unit and a cooling unit are used to obtain a curved tubular segment without spaces between the curved external tubular element and the curved internal tubular element.

摘要： A tube for use in a heat exchanger comprises a base portion, an upper portion spaced from and opposing the base portion, and a partitioning wall extending between the base portion and the upper portion to divide a hollow interior of the tube into a first flow channel and a second flow channel. The partitioning wall includes a plurality of windows spaced from each other in a longitudinal direction of the tube to provide fluid communication between the first flow channel and the second flow channel. At least one of the windows includes a tabbed portion of the partitioning wall bent to extend into one of the first flow channel or the second flow channel.

摘要： An automotive component manufacturing method includes a molding process of pressing a portion of a hollow tube formed from a metal material, or a composite material including a metal and a resin, so as to deform the portion of the hollow tube, from a tube outer side toward a tube inner side, to beyond an axial center of the hollow tube, and mold the portion of the hollow tube into a deformed section deformed with a concave profile; and a deformation process of deforming a location having a high level of residual stress in a closed cross-section configured by the deformed section so as to deform the location out-of-plane.
