Some embodiments of the present disclosure provide manufacturing methods for a wheel rim, a spoke and a steel wheel and a steel wheel formed by the methods. The methods includes that: a wheel rim/a spoke blank is heated in a heating furnace, and the heated wheel rim/the heated spoke blank is transferred onto a hot press. A temperature of the wheel rim/the spoke blank being required to be kept above a required temperature in a process of transferring the heated wheel rim/the heated spoke blank to the hot press. Then the wheel rim/the spoke blank is formed in the hot press. A formed wheel rim and a formed spoke are connected to product a steel wheel.

A method for producing a drop centre rim and to a drop centre rim for vehicle wheels of commercial vehicles. The rim has a plurality of zones, which form an inner rim flange and an outer rim flange, an inner steep-tapered bead seat and an outer steep-tapered bead seat and a rim drop centre with a drop centre base, an inner drop centre flank and an outer drop centre flank between the steep-tapered bead seats, wherein one of the zones is provided as a disc attachment region for a wheel disc, and the drop centre rim has at least one partial zone with a reduced wall thickness relative to the other zones. It is envisaged that at least one of the steep-tapered bead seats, preferably both steep-tapered bead seats, has/have a section with a wall thickness reduction of more than 20% relative to the wall thickness in the zone provided as the disc attachment region, wherein the wall thickness reduction is produced during one of the profiling steps.

The present disclosure discloses a wheel rim finishing device. A motor is fixedly mounted on a stand through a shaft sleeve I. A supporting body is arranged on the stand. The side, close to a locating disk, of the supporting body is provided with an outer roller. An inner driving roller body and an inner driven roller body are arranged at a position, close to the outer roller, on the inner side of the locating disk. The wheel rim finishing device is simple in structure and high in universality, and may adapt to wheel types with different rim structures.

A process for manufacturing a light-alloy hybrid wheel, implements the following separate operation phases: making a flange with an internal profile capable of constituting a tire bead seat; making a rim with, on one side, an outer profile capable of constituting a tire bead seat and, on the other side, a circular flank for assembly with a part of the flange; and assembling the flange with the rim, at the seat of said flange and the circular flank of the rim. The rim is made according to the following consecutive operations: an operation of manufacturing a circular flank; then an operation of expanding said circular flank to the size of the final rim in a single step; then an operation of cold or hot flospinning of said circular flank so as to obtain the rim in the final shape and profile thereof, comprising a shoulder only on the side that will not be welded to the flange.

A method for manufacturing a one-piece wheel by forging includes: producing an integral forging comprising: a disc portion, a rim portion, and an annular protrusion protruding from one side of the disc portion in a forging method; producing an outer bend by bending the annular protrusion through a flow-forming process; and forming a hollow portion by welding one end of the outer bend to one side of the rim portion. The method manufactures the one-piece wheel having stronger shear strength and stiffness and better fatigue life even while reducing the noise using the forging method.

The present disclosure provides a floating block of a hub shaping mold. The floating block can include: at least one inner support member having a first side and a second side opposite to each other, wherein the first side of the at least one inner support member can include a first arc surface, and at least one first bulge can be arranged on the first arc surface; at least one outer pressing member having a first side and a second side opposite to each other, wherein the first side of the at least one outer pressing member can include a second arc surface matched with the first arc surface, at least one second bulge can be arranged on the second arc surface, and the at least one first bulge and the at least one second bulge can be arranged in a staggered manner.
