Die sets and tools using such die sets, are described which promote axial alignment of the dies during die closure. In addition, jaw sets for tools are described that promote axial alignment of the jaws during die closure. Also described are related methods using the die sets and/or tools with such die sets.

A swage die includes a plurality of teeth aligned in a generally arcuate array. Each tooth of the plurality of teeth includes a first sidewall, an opposing second sidewall, a first endwall, and an opposing second endwall. The swage die further includes a plurality of first supports, each of the plurality of first supports extending between and connected to first endwalls of neighboring teeth, and a plurality of second supports, each of the plurality of second supports extending between and connected to second endwalls of neighboring teeth. The swage die further includes a plurality of stops, each of the plurality of stops extending from a first support towards a neighboring first support or from a second support towards a neighboring second support.

A connection element consists of a longitudinally oriented support structure that is at least partially hollow and a sensor unit that is arranged in the inside of the support structure, is connected to a signal transmission device, and is non-positively connected to the support structure. The required force for the non-positive connection is produced by internal stresses after a plastic deformation of the support structure during a joining process of the support structure and the sensor unit. A method for manufacturing a connection element consisting of a support structure that is at least partially hollow and a sensor unit includes positioning the sensor unit in a region of the support structure and, using radially movable tool segments, exerting a force on the support structure in the radial direction and at the same time reducing the periphery of the support structure in the region in which the sensor unit is positioned.

A joint structure includes a shaft member and a cylindrical member. The cylindrical member includes a plurality of first crimped portions crimped along a plurality of axial grooves provided in an axial direction of the shaft member, respectively, and a second crimped portion which fits the axial grooves and is crimped along a circumferential groove, the circumferential groove being provided on a circumferential surface of the shaft member by reducing a diameter of an axially intermediate portion of the cylindrical member in a radial direction. Each of the first crimped portions project from an inner circumferential surface of the cylindrical member as a projection. A position of a tip of the projection in an axis direction of the projection is set displaced from a position of a lowest point of the circumferential groove such that the tip is not located at the lowest point of the circumferential groove.

A method of manufacturing a swaging tool includes forming a body of the swaging tool via additive manufacturing, forming a jaw of the swaging tool, and connecting the jaw with the body. Forming the body may include providing a portion of the body with a lattice structure. The portion may be internal and may not be externally accessible. Forming the body may include adding material to form at least one recess in an outer surface of the body. The method may include conducting a stress analysis. The at least one recess may be formed based on or according to the stress analysis.

A cheek plate for producing a non-detachable pipe joint having an upper cheek half and a lower cheek half, at least one swivel pin which pivotally mounts at least one cheek half, and a receiving region formed between the upper cheek half and the lower cheek half and having a receiving region axis, the at least one cheek half being able to pivot between an open position and a closed position substantially transversely with respect to the receiving region axis. The problem of providing a cheek plate such that the cheek plate permits pressing transverse to the receiving region axis and at the same time a reduction in workpiece size is permitted is solved in that at least one pushing unit is provided, the pushing unit being displaceable at least partially in parallel with the receiving region axis.

A method is provided for connecting a first component to a second component, wherein the first component has a deformation region. The deformation region is at least partially heated in a first step. In a second step an inner die, having an optical component for plastic deformation, is provided. In a third step the first component is plastically deformed in the deformation region in order to connect the first component to the second component. Light for heating the first component is directed at the deformation region by means of the optical component of the inner die in the first and/or third step.

A heat exchanger having at least one inner conduit comprising of a second tubular member coaxially disposed within a first tubular member, wherein the second tubular member outer surface is in contact with the first tubular member inner surface. Each of the first and second tubular members is composed of a material with an approximately 0.015 inch maximum wall thickness.

Each of the first and second tubular members is composed of a material with an approximately 0.015 inch maximum wall thickness.

A gas generator includes at least two functional subassemblies and at least two retention parts. The functional subassemblies each have an axis defining an axial direction and at least one outer dimension in a plane normal to the axial direction. The retention parts are each radially crimped for retaining one of the at least two functional subassemblies on the gas generator. The at least two retention parts are formed on the same part of the gas generator and the at least two functional subassemblies are positioned on the gas generator with a center distance of axes less than or equal to 1.5 times this outer dimension and that each retention part is radially crimped over at least 90% of its periphery.
