    1. Flash Butt Welding MachineIt is used for welding the steel wheel rim after the welding joint has been flattened. The work piece clamping, welding and weld slag removing are all driven by the hydraulic system.
    1. Trimmer, Planisher, End Cutting MachineThe wheel manufacturing equipment comes with a single piece design and shares one hydraulic system, which reduces the number of needed operators and saves floor space.
      The automatic feeding and discharging mechanism has a 3 process, and 4 location design
    1. Flaring MachineThe horizontal flaring machine is an important piece of rim equipment in wheel rim production lines. It is designed to flare rims after the welding and re-rounding processes. The machine can flare both edges on the rim into a horn mouth, making it convenient for the following roll forming process.
    1. Roll Forming Machine

      Roll forming machine is also known as a wheel rim forming machine, and is used for symmetrical or asymmetrical roll forming of steel wheel rims. The roll forming equipment consists of the main machine, hydraulic transmission system, pneumatic system, PC control system and lubrication system.

    1. Valve Hole Punching PressLittleDuck Precision Machinery Company supplies valve hole punching presses for pressing and punching valve holes on the tubeless wheel rims. This hole punching machine uses a dual power hydraulic system and is comprised of the main machine, the drive mechanism, and the electrical control cabinet.

Here at LittleDuck Group, we offer customers complete production lines and single machines for the production of steel wheel rims. Our wheel rim machinery is used to make steel wheel rims for cars, trucks, buses, tractors, farm vehicles and construction vehicles. As a professional manufacturer of wheel rim manufacturing equipment, we can design and make steel wheel rim manufacturing lines for the production of 10 to 54 inch wheel rims.

Advantages
1. Labor and Space Efficient Layout: According to production processes from rim band coiling to butt welding, trimming, flaring and roll forming, and expanding sizing, these steel wheel rim lines have a compact, efficient and labor saving layout, saving production areas for users and allowing easy logistical arrangements.

2. High Automation and Low Rejection Rate: LittleDuck steel wheel rim production lines use PLC control systems and mechanical arm transport systems to ensure the high automation, which improves the working efficiency, reduces labor intensity, and lowers labor costs.

Through in-depth design, accurate positioning, and precise processing, the wheel rim manufacturing line guarantees the high quality end products and effectively controls the rejection rate, within 0.5%.

3. Remote Control and Maintenance: PLC control systems carry out a fast transmission of production data using remote control technology, making it convenient for controlling production processes. In addition, the steel wheel rim line can achieve remote control maintenance via an internet connection, making daily maintenance and inspection easy.

Main Specifications
According to wheel rim categories, diameters and production processes, we can design and manufacture small, large and ultra-large wheel rim manufacturing lines. The processing range of the lines can be adjusted according to customer’s requirements.

1. Small Type Wheel Rim Line
For production of passenger car wheel rims
Diameter: 13~18"
Width: 3-10"
Steel plate thickness: ≤4mm

2. Large Type Wheel Rim Line
For production of tubeless wheel rims of trucks and buses
Diameter: 17.5~26"
Width: 5.5-16"
Steel plate thickness: ≤8mm

3. Ultra Large Type Wheel Rim Line
For production of wheel rims of construction vehicles, agricultural vehicles and tractors
Diameter: 20~54"
Width: 7-28"
Steel plate thickness: ≤8mm

Operation Modes
In accordance with user's production requirements, LittleDuck supplies semi-automatic steel wheel rim manufacturing line and fully automatic steel wheel manufacturing lines. The first needs 10 to 12 people to operate it, completing material loading and unloading, as well as machining operations. The fully automatic one only needs 3-5 operators as feeding and discharging are all automatic, and achieves an automatic operation and material transportation.

Process Arrangement of Wheel Rim Production Lines
The production process arrangement of the steel wheel rim line is based on the steel plates that customers use. These steel plates have been cut to length by the steel supplier.

We can design the most appropriate layout of the production process and machining technology according to user’s requirements. Conventional production processes of the small, large and ultra-large wheel rim lines are shown in the following table for reference.

**NOTES
#1.Generally, the small wheel rim lien does not need to flatten the welding joint. However, if it is used to produce small construction car wheel rims with a thickness of more than 4mm, this wheel rim equipment needs to undergo flattening.
#2. Small wheel rim lines and large wheel rim lines don’t require roll forming for non-skid patterns that are used to increase the abrasion between the rim and the tire.
#3. Edge flanging is an elaborate cold rolling processes for keeping two edges of the wheel rim smooth and burr free. It is optional for users according to their requirements for machining precision.
#4. The wheel rims produced on the small and large wheel rim lines are often jointed with wheel discs in a welding process, while those produced in ultra-large wheel rim lines are generally connected to the wheel disc using bolts.
