Abstract:
A press fitting, including a tubular component and an end portion of the tubular component which can be compressed to make a connection. The end portion has an opening to receive a tube and a first region having an annular ridge to receive a sealing ring. A second region is arranged on the side of the ridge adjacent the opening and a third region is arranged on the side of the ridge remote from the opening. The overall wall thickness of the press fitting in the second region is increased at least in a section or sections in comparison with the wall thickness of the tubular component in the third region.
Abstract:
A method for connecting two components. The method includes heating a deformation region of at least one component part to provide complete heating. The at least one component part is plastically deformed after the complete heating of the deformation region.
Abstract:
A hand held flaring tool includes a receiving portion for receiving an end of a tube, a stop element, a locking mechanism and a flaring mechanism. The stop element is movably disposed at the receiving portion and is movable between a stopping position, where the stop element limits insertion of the tube at the receiving portion to set the tube at an appropriate location for flaring the end of the tube, and a flaring position, where the stop element is moved to a position remote from the end of the tube. The locking mechanism is operable to lock the tube at the receiving portion when the tube is inserted into engagement with the stop element. The flaring mechanism is operable to move a flaring mandrel towards and into engagement with the end of the tube to flare the end of the tube.
Abstract:
A method for manufacturing an integrated aluminum alloy bicycle front fork is revealed. Aluminum alloy is extruded to form substrate having three rectangular bars. Cut the substrate to get a blank. The blank is set into a mold for forging the three rectangular bars into three round bars. Then burr and waste material are removed. Next the blank is set into another mold for extruding the three round bars and the three round bars are punched to have guide holes. The round bars are drilled along the guide holes and penetrated to form round tubes. A tube opening of two round tubes is flattened and narrowed. Then the two round tubes are bent downward to form fork tubes of a front fork. The rest tube forms a front fork stem. Thereby an integrated light weighted front fork with good structural strength and beautiful appearance is produced.
Abstract:
A nozzle assembly for a welding torch and a welding torch including said nozzle assembly is provided. The nozzle assembly generally comprises a nozzle body having an internal bore with a plurality of detents disposed within a portion of the internal bore and an insert assembly having a proximal exterior surface with a plurality of sealing members. The insert assembly is adapted to be secured within the internal bore of the nozzle body by the plurality of sealing members progressively engaging the plurality of detents.
Abstract:
A vehicular system is provided with a substantially hollow member having a long axis, a short axis, and an outer surface substantially parallel to the long axis. The outer surface includes a plurality of notched elements configured to reduce strain from bending the member in the direction of the short axis, e.g., by a stretch bending process. The hollow member may also include an outer surface that is curved substantially in the direction of the short axis. A method of making the vehicular assembly includes the steps: providing a substantially hollow member having a long axis, a short axis, and an outer surface substantially parallel to the long axis; cutting a plurality of notched elements into the outer surface; and bending the member such that the portion of the outer surface in proximity to the notched elements is in tension and curved in the short axis direction.
Abstract:
A method of flange trimming a sheet metal panel to form a part including flanges for subsequent hemming or weld operation is disclosed. The method utilizes an electro-hydraulic forming (EHF) tool to form a channel within which a flange is cut out in a trimming operation. A combined flange/trim die may be provided in which both a channel forming operation and a flange trimming operation may be performed. A manufacturing system for fabricating a part by forming a channel in a peripheral portion and cutting the channel area to form a flange. The method also relates to a die for an EHF tool that defines a channel-shaped recess and has a trim edge for cutting a flange into the channel.
Abstract:
A first part, a second part, and a seal ring are fastened together to form a pressure structure configured for a spacecraft structure of a spacecraft, wherein the first part and the second part are each formed from a single workpiece.
Abstract:
The invention relates to a process and an apparatus for producing a profiled sheet, in which the sheet is provided with a corrugation which runs obliquely with respect to the edges of the sheet and has a substantially constant angle of inclination. At least one edge region of the sheet is deformed by means of a ram-like deformation tool (6) which is alternately brought into contact with the edge region and removed from the edge region.
Abstract:
The present invention provides a deburring device for a punch press which can remove burrs produced along a slot or a cut portion formed in a plate material by punching or cutting using a punch press so that the removal is carried out as a process with the same punch press. A deburring device 6 for a punch press has an upper tool 7 and a lower tool 8 arranged opposite each other. The upper and lower tools 7, 8 each have a ball holding member 22, 32, respectively, and a ball 23, 33, respectively, rotatably supported by the ball holding member and projecting from a surface of the ball holding member 22, 32 toward an opposite surface of the opposite ball holding member 32, 22. Each of the upper and lower balls 23, 33 has a diameter larger than the width of the slot A, in its portion projecting from the ball holding member 22, 32, respectively, the slot A being formed in the plate material W so as to extend across the plane. The plate material W moves with the vertical pair of balls 23, 33 partly fitted into the slot A and with the plate material W sandwiched between the upper and lower balls 23, 33 to continuously remove burrs (a) produced along a longitudinal direction of the slot A. The deburring device 6 continuously removes not only the burrs produced along the slot A but also those produced along a cut portion in the plate material W as described above.
