What is Rear Wheel
Usage: Rear wheel components (hub spline, axle head positioning surface) are the core transmission/load-bearing structure of motorcycles, electric two-wheelers, and small passenger cars, which directly affect the power transmission efficiency and driving stability.
Material/geometric characteristics: Carbon steel (HRC25-30 quenching and tempering) or aluminum alloy (aging treatment), which is a circular thin-walled structure, which needs to be processed with high-precision spline tooth shape and positioning surface, and the tolerance requirements are strict (within ±0.03mm).
Common risks: traditional processes are prone to quality problems such as tooth top wear, tooth direction deviation, and coaxiality deviation; Uneven force on the ring workpiece leads to deformation; Multi-process turnover increases the surface damage rate, and the scrap rate is as high as 15%.
Rear Wheel Machining Core Pain Point
Pain point 1: It is difficult to control the accuracy of the spline tooth shape
- Efficiency impact: Traditional milling/gear shaping in multiple processes extends production cycles by 40%
- Cost impact: The rework cost increases by 50 yuan/piece, and the annual additional expenditure is about 60,000 yuan
- Quality Impact: Scrap rate reaches 15%, leading to delays in order delivery
Pain point 2: The positioning of the ring workpiece clamping is unstable
- Efficiency impact: 30% increase in clamping time and 20% reduction in single-shift capacity
- Cost Impact: The annual expenditure of customized fixtures is 20,000 yuan, and poor equipment adaptability leads to wasted resources
- Quality impact: The coaxiality defect rate is 12%, and the complaint rate of transmission noise increases
Pain point 3: low processing efficiency and cumbersome process turnover
- Efficiency impact: Non-cutting time accounts for 40%, and the production capacity is less than 200 pieces in a single shift
- Cost impact: Labor turnover costs increased by 8 yuan/piece, and the annual expenditure was about 96,000 yuan
- Quality Impact: Multi-process leads to an 8% surface damage rate and an increase in customer return rates
Rear Wheel Machining Process
Complete processing link: blank pretreatment→ tooling debugging→ clamping positioning→ broaching processing→ discharge detection→ post-processing and warehousing
The core function of HW0508: to realize automatic loading and unloading, uniform speed broaching in the broaching process, connect the clamping and testing links, and reduce manual intervention. The connection logic of each link: pretreatment ensures that the hardness of the material meets the standard→ tooling debugging matches the size of the workpiece→ clamping positioning ensures coaxiality→ one-time forming of broaching processing→ detection and verification accuracy→ post-processing rust prevention and warehousing, and the full-link closed-loop improves efficiency.
