The present invention explains a process for manufacturing tubeless vehicle wheel without welding using a hoop 100 having an outboard end 101, a centre region 102, an inboard end 103. The process includes spinning the outboard end 101 to obtain a disc region 202, spinning disc end 203 to obtain preform nave region 301. Forming the disc region 202 to obtain a disc profile 401 and a nave region 403, forming the centre region 102, inboard end 103 to obtain a straight rim profile 402. Spinning and forming outer end 405 of the straight rim profile 402 to obtain an outboard flange 502a and spinning the straight rim profile 402 to obtain a concave rim profile 601a with a preform inboard flange 602a. Spinning the concave rim profile 601a to obtain bead seats 701a, well region 703a and, forming the preform inboard flange 602a to obtain an inboard flange 704a.

Device for shaping a component, comprising a first tool and a second tool, which can be moved relative to one another along a movement axis to shape a component to be placed between the tools, wherein a surface of the first tool can be extended transverse to the movement axis in an extension region. With the described device and with the described method, components, in particular sheet steel components, can be shaped in such a way that contours that are oriented in parallel to a movement axis of the tools are particularly well formed. In particular circular shapes can thus be formed with particularly good accuracy. Negative influences of fluctuations of the thickness of the component can be offset. The device and the method are particularly suitable for the production of wheel rims for motor vehicles.

The invention discloses aluminum alloy wheel shape-correcting equipment which comprises rack, an output end of positioning air cylinder is arranged at the bottom of the rack corresponding to the center of the upper rotating disc and is vertically and upwards connected with positioning cone.

A wheel disc including a bolt hole for bolt fastening, includes a first region extending to have a predetermined width in a circumferential direction of the bolt hole and a second region, other than the first region, wherein the first region has an average tensile strength lower than that of the second region.

A metal can with a monolithic laminated hermetic seal is provided. The lid and sidewall of a can each include a laminated layer bonded to an interior surface. The lid and sidewall of the can are rolled to form a double seam and mechanically seal the can. When the double seal is formed through the mechanical rolling process and before heating, a bi-laminate layer forms between the adjacent laminated interior surfaces. The bi-laminate layer is then heated, causing each laminate layer to melt and fuse with the adjacent laminate layer. This creates a monolithic laminate layer that fills gaps within the double seam to form a hermetic seal that is impervious to air, water, gas, liquids, and other fluids.

A fixing device for repairing an aluminum alloy wheel hub includes a base and universal wheels connected with the bottom of the base through support legs, wherein one side of the bottom plate is connected with air cylinders; the top of the bottom plate is connected with a fixing plate through a rotating shaft mounted rotationally; corresponding sides of vertical plates at the two sides of the fixing plate are each connected with a pressing plate through two sets of springs; adjusting bolts penetrate through the middles of the vertical plates; a first groove is formed in the middle of the fixing plate; two sets of guide rollers are rotationally mounted in the first groove; a top plate is fixedly mounted at the top of the bracket; a push plate is connected with the bottom of the top plate through a second hydraulic cylinder.

The present invention is a mini wheel CNC and manual lathe with wheel straightener and method for using said lathe.

A vehicle wheel disc includes a flat plate-shaped hub-mounted part, a cylindrical rim-mounted part, and a hat-shaped part. The hat-shaped part includes a hat top portion, a hat inner peripheral portion, and a hat outer peripheral portion. At a border between the hub-mounted part and the hat inner peripheral portion, a first connecting portion is provided, and at a border between the hat top portion and the hat outer peripheral portion, a second connecting portion is provided. The plate thickness of the hat outer peripheral portion is smaller than the plate thickness of an intermediate portion that is a portion from a border between the first connecting portion and the hat inner peripheral portion to a border between the hat top portion and the second connecting portion in the disc radial direction.
