STAKING ASSEMBLY MANUFACTURING METHOD, HUB UNIT BEARING MANUFACTURING METHOD, AND VEHICLE MANUFACTURING METHOD
20220143679 · 2022-05-12 · ·

A method of manufacturing a hub unit bearing (1) includes the step of applying an axial load to a shaft end of a hub body (21) so that a staking portion (26) for inner races (22a, 22b) is formed in the hub body (21). The load is adjusted based on at least one of first information acquired before applying the load and second information acquired while applying the load.

TRAPPED PARTS VIA SWAGING
20230256496 · 2023-08-17 ·

A method of operating a swaging station includes removably coupling an insert to a distal end of a mandrel and advancing the insert and the distal end of the mandrel into a hollow interior of a tubular body defined by an inner circumferential surface thereof. A die of the swaging station is utilized to deform the tubular body radially inwardly to cause the inner circumferential surface of the tubular body to contact the insert to capture the insert within the tubular body at a desired axial position. The mandrel and die are retracted to result in a tubular component having an integrated insert disposed therein.

SLEEVE WITH RELIEF CAVITY FOR FLANGED TUBE ASSEMBLY
20220134414 · 2022-05-05 ·

A flanged tube assembly includes a rigid tube (10) and a sleeve (12) disposed about an axial end portion of the tube. The axial end portion (18) of the tube (10) includes a flange portion (24) that is formed by the tube wall (36) being radially outwardly deformed over an axial end surface of the sleeve. The sleeve (12) has a radially inner surface (28), and a portion of the tube wall (36) inside of the sleeve (12) is deformed to engage and conform to the radially inner surface of the sleeve, thereby forming a non-welded connection between the sleeve and the tube. The radially inner surface of the sleeve proximal the flange defines a relief cavity (56) that receives the deformed portion of tube wall when the tube wall is deformed during the formation of the flange (24).

Forward stroke pipe fitting swage machine systems and methods

Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. Additionally, the system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch on the grab ring to facilitate securing the pipe fitting to the swage machine, a die plate in which a die is loaded, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to push the die plate over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment via a forward stroke.

Method for manufacturing combined hollow camshaft by axial-compression upsetting-deformation technique

A method for manufacturing a hollow camshaft is provided, and more particularly, a method for manufacturing a combined hollow camshaft by an axial-compression upsetting-deformation technique. The present method solves a problem that the current camshaft manufactured in an internal high-pressure expansion manner in the prior art has the insufficient locking force to cause the loosening of a cam. The method is as follows: a camshaft is formed by combining two independent units, namely a cam and a shaft tube. Non-circular countersinks are distributed on two sides of the cam. Thrust steps are formed on the shaft tube correspondingly. The cam is placed between the two thrust steps of the shaft tube. The locking force is applied to the cam by utilizing the thrust steps on the two sides of the cam based on thermal expansion and contraction. Simultaneously, the thrust steps lock the cam with the countersinks.

Device and method for producing a component

A device and method for producing a component are provided. The device or method includes steps or units for providing a first component element having a recess in or on a first surface of the first component element, and for positioning a second component element in the region of the recess. The device or method also includes a step or unit for pressing the first component element and the second component element together, and as a result forming a material fit, positive fit and/or non-positive fit between the first and the second component elements at least in the region of the recess. The positioning and the pressing can be carried out or are carried out functionally, in particular, spatially and/or temporally, in terms of equipment, separately from each other.
