Method of making whole car wheel rim

1468739 Making wheel rims; stamping; foundry moulds GEORG FISCHER AG 9 Oct 1974 [16 Oct 1973] 43833/74 Headings B3A B3F and B3Q A method of making an annular rim member for use in a wheel to receive a pneumatic tyre, comprises forming a mould cavity with a radial dimension oversize and/or undersize over an annular portion of the rim periphery, casting an iron-carbon melt into the cavity to form the rim member, removing the member from the cavity, and working the member radially to bring it to the required dimensions by means of plastic deformation. The melt may be of cast iron or cast steel and the former is treated prior to pouring to form a ductile casting whereas a cast steel member is heat treated after solidification to have the necessary ductility. The rim member is cast in a said mould, which preferably includes a hollow annular core (3), an annular pouring basin (5) and feeding duets (7), Fig. 2 (not shown). The core (3) bridges the mould portion (4) and defines the radially outer surface 19 of the rim, Fig. 6, which is shown by chain lines in the as-cast condition and is I-10% oversize. The as-cast rim 10<SP>1</SP>, Fig. 7 is moved step-by-step between shaping operations on previously cast rims along rails 30 of a press until it rests on cross-bars 32 on lifting rods 31, which raise the rim into an open ring of die segments 40 mounted on a movable ring 39. The die segments are raised by the ring and as the ring moves upwardly they are driven inwardly by sloping surfaces 37 in a guide ring 36 to form the ring 10 to its finished dimensions. The die segments are then lowered, thereby opening them and the finished rim is lowered on to the rails 30. Alternatively an undersized rim may be expanded or the rim may be formed with undersized and oversized portions which are expanded and compressed to the required dimensions respectively.

Drop center truck rim and method of forming same

A method of forming a drop center truck rim from a flat steel strip rolled into the form of a smooth cylinder and welded together along the abutting axial edges. The weld flash build-up on the smooth cylinder is removed before the cylinder is formed into the desired rim profile. The cylinder is then simultaneously subjected to an axial load and external fluid pressure to force the cylinder radially against an internal die to form a circumferential well in the central portion of the cylinder, while flaring the end portions of the cylinder. Next, the low stress areas of the desired rim profile, which are the end portions of the rim, are shear formed to reduce the thickness of the steel cylinder in the end portions, while retaining the original thickness of the flat strip in the central well. The final rim profile is then produced by roll forming, after which the rim is sized.

Flat base truck rim forming system

Abstract Of The Disclosure A system for forming flat base truck rims from flat strips of steel rolled into the form of smooth cylinders and welded together along the abutting axial edges. The system is capable of forming rims from hot rolled, rimmed, low carbon steel strips. The smooth cylinder is initially formed by a plurality of dies located at opposite ends of the cylinder and mounted for advancing movement relatively toward each other in the direction of the cylinder axis to flare a first end of the cylinder radially outwardly while rough forming a rim gutter on the other end of the cylinder. The radial thickness of the metal forming the rim gutter is increased during the rough forming thereof by applying a compressive axial load to the cylinder and providing a gutter-forming die cavity wider than the starting thickness of the cylinder. The rim gutter is warm or hot formed by heating that end of the cylinder before advancing the dies to roughly form the gutter. The flaring step is performed with an expandable die which is expanded during the flaring step and then collapsed and advanced to deform the outwardly flared portion of the cylinder to rough form a fixed flange, so that different portions of the same die are used to effect both the flaring and the flange forming. The flat base of the rim is shear formed to reduce the radial thickness thereof in the low stress area between the gutter and the fixed flange. The final profile in the fixed flange and the gutter is produced by roll forming the rim.

Method of spin forming an automotive wheel rim

The present invention is directed to a method of manufacturing a three piece aluminum wheel assembly comprising the steps of providing a pair of circular blanks made of a heat treatable alloy to be formed into preforms of a general shape. The preforms are subjected to a quenching step in an unconstrained condition to allow for natural thermal deformation during the quenching operation. The as quenched preforms are then subjected to a first forming operation using spin forming to remove the effects of the thermal deformation in the preform, followed by a second forming step using spin forming to shape the component to its desired final shape. The components are then exposed to precipitation heating and finishing to yield the final product.
