A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped. The crimping tool has a simple structure and good crimping performance, so that the workpiece is uniformly stressed and burrs on the workpiece can be reduced.

In a method for joining members, a first tube, and a second tube capable of being inserted into the first tube are prepared. The second tube is inserted in a tube hole of the first tube in an axial direction of the first tube. The second tube is radially expanded toward the first tube so that the first tube and the second tube are joined by press-fitting. The first tube is made of a material having a spring back amount larger than a spring back amount of the second tube.

A method for making an air spring assembly, including the steps of providing a bellow, a support ring, and a guide tube. The support ring is positioned relative to a bellow adapter such that a portion of the bellow adapter extends through the support ring. The bellow is then positioned such that a portion of the bellow extends over the support ring and a portion of the bellow adapter. The guide tube is then positioned relative to the bellow and the support ring, such that a portion of the bellow extends into the guide tube and the guide tube is supported by the bellow adapter, and a portion of the guide tube is supported by a ridge support fixture. The first clamp and second clamp are then moved towards the guide tube, applying force to the guide tube, simultaneously forming a first crimp and a second crimp.

A crimping system for crimping fittings on hoses is disclosed and include an interface and a crimper machine. The crimper machine is configured to analyze collected information based on identified hose and fitting properties; perform a crimping operation based on the collected information and the identified hose and fitting properties; measure crimping characteristics for the crimping operation; generate an alert based on the measured crimping characteristics and the collected information; and provide the alert to the interface.

Embodiments of the present disclosure provide an axial swage tool configured to axially swage a fitting to a tube, a cable, or other such item of manufacture. The swage tool can be configured to utilize swaging engagement members for grasping and driving a swaging ring over a fitting. The swaging ring thereby radially compresses the fitting around the tube or other item.

A press ring (1) for pressing tubular workpieces (35), comprising: at least two movable press jaws (3); and at least one connecting press jaw (5) connecting the movable press jaws (3); wherein the movable press jaws (3) are each hinged at their proximal ends to the connecting press jaw (5) by means of respective bolts (9), so that the distal ends (7) of the movable press jaws (3) can be rotated towards and away from each other to close respectively open the press ring (1) to receive a workpiece (35) therein, and characterized in that the respective bolts (9) are arranged in elongated holes (11), allowing a translational displacement of the bolts (9) in the elongated holes (11) upon rotating the movable press jaws (3).

A universal pipe connection system includes a fitting with a tubular body and an annular bulge defining an annular groove on the inner side of a tubular body, which houses a sealing gasket. The tubular body receives the end portion of a pipe so that a pressing tool having opposite pressing jaws can engage the tubular body and generate a circumferential band adjacent to the bulge by mechanically clamping the tubular body in the circumferential and axial directions and causing a deformation of the annular bulge, which presses the gasket, and generates a seal between the tubular body and the end of the pipe inserted therein. The annular bulge and the corresponding annular groove have a geometry and size adapted to cooperate with two different types of pressing tools, one with a M profile and one with a V profile, which may be present in the alternative or in combination.

A pressing tool for producing a non-detachable pipe connection, including holding means for holding the periphery of at least one first tubular or sleeve-shaped connection element and including sliding means for peripherally holding and axially displacing at least one second tubular or sleeve-shaped connection element. The sliding means is movable along a first axial operating direction towards the holding means to press two interengaging tubular or sleeve-shaped connection elements. The pressing tool easily allows pipe connections to be produced in a more flexible and efficient way in that the sliding means are movable towards the holding means along a second axial operating direction opposite the first axial operating direction to press two interengaging tubular or sleeve-shaped connection elements.
