The manufacturing process for a tire building machine covers component machining, sheet metal fabrication, assembly of core functional units, electrical and pneumatic integration, and machine commissioning. Each stage requires accurate manufacturing, proper alignment, and functional testing to ensure that the machine operates according to its design requirements.
Component machining and preparation
Component machining establishes the dimensional accuracy required for machine assembly. This stage includes metal structural parts, transmission components, and the selection of electrical and pneumatic components.
Machining metal structural components
CNC cutting machines, boring and milling machines, and other equipment are used to machine cast and forged components such as the frame and side plates. The geometric tolerances must be controlled within ±0.05 mm to provide an accurate foundation for subsequent assembly.
Machining transmission components
Transmission parts, including ball screws, synchronous pulleys, and gears, undergo heat treatment and grinding to achieve the required transmission accuracy and service life.
Preparing electrical and pneumatic components
Industrial grade components, such as servo motors, PLC controllers, and pneumatic solenoid valves, are selected and procured. Pressure resistance and signal stability tests are carried out before these components are integrated into the machine.
Sheet metal fabrication and surface treatment
Laser cutting machines are used to cut sheet metal parts for the machine enclosure and protective doors. Bending machines and welding robots then carry out forming and welding operations.
The fabricated sheet metal parts undergo pickling and phosphating, followed by electrostatic powder coating. These treatments improve rust and corrosion resistance and help maintain a consistent equipment finish in accordance with industrial safety protection requirements.
Assembly of core functional units
Assembly of the core functional units has a direct effect on machine performance. The main work includes the building drum, material feeding and splicing mechanisms, and the pressure application and cutting units.
Building drum assembly
The segments of the building drum and its expansion mechanism are assembled and adjusted. Radial and axial runout must be checked to maintain the required drum accuracy and support circumferential uniformity during tire building.
Feeding and splicing mechanism assembly
Feeding roll groups for cord fabric, tread, and sidewall materials are installed. Their synchronized operation is adjusted to keep the positioning error of the rubber materials within ±1 mm.
Pressure application and cutting unit assembly
Pressure rolls, cutting blades, and other actuating components are assembled and adjusted. Pressure settings and cutting accuracy are checked to ensure close contact between the tire body layers and reduce the risk of trapped air bubbles.
Electrical and pneumatic system integration
The servo control system, human machine interface, and safety protection circuits are installed and wired according to the electrical schematics. Signal transmission stability is checked to confirm that the control system communicates reliably with the machine components.
The pneumatic system is adjusted to the required operating pressure. Cylinders and solenoid valves are checked to ensure accurate movement without air leaks or sticking. Emergency stop buttons, travel limit devices, and other safety protection components are also configured and tested.
Unloaded commissioning
During unloaded commissioning, the machine is powered on and its mechanisms are operated without material. Engineers check transmission noise and operating speed against the design requirements and adjust the motion parameters of each axis as necessary.
This stage helps identify abnormal movement, transmission problems, or control issues before material is introduced for forming tests.
Loaded commissioning
During loaded commissioning, a simulated tire blank is used for trial forming. The tests assess tire body splicing accuracy and forming efficiency. Machine parameters are adjusted according to the test results.
Each commissioning session generally requires at least 50 simulated forming operations. These repeated tests provide a basis for evaluating machine operation and confirming the consistency of the forming process before production use.
Custom precision machining for tire building equipment
In addition to supporting industrial equipment manufacturing, Hansheng Automation provides custom precision machining for nonstandard components based on customer supplied drawings. We manufacture parts according to specified dimensions, tolerances, and structural requirements to support equipment assembly, maintenance, and replacement needs.
