As robots rapidly integrate into people's lives, the support of Goanwin stamping presses is indispensable.
In humanoid robots, core components manufactured using stamping processes are mainly concentrated in structural parts and key components of reducers. Stamping technology, due to its high efficiency, high precision, and suitability for mass production, plays a crucial role in light weighting and cost control.
According to the latest industry trends and technical analysis, the main components produced through stamping processes include:
1. Reducer Flexible Gear
This is currently one of the most prominent applications of stamping technology in the field of humanoid robots. The flexible gear is a core component of harmonic reducers. Traditionally, it was manufactured using forging processes, which are complex and result in high material waste. In recent years, Chinese companies have pioneered the "precision stamping + gradient quenching" technology, successfully achieving the stamping manufacturing of flexible gears:
Process Advantages: Reducing the number of processes from 12 to 5, increasing material utilization from 60% to 92%, and reducing costs by 40%.
Performance Breakthrough: Stamped flexible gears can have wall thicknesses as thin as 1.2 mm, and fatigue life exceeds 20,000 hours, surpassing industry standards.
Industry Impact: This technology broke the long-term monopoly of companies like Harmonic Drive Systems of Japan, becoming a key breakthrough in domestic production.
2. Lead Screw End Cap Assembly
In planetary roller screw systems, the end cap is a crucial structural component used for fixing and sealing. Companies like CATL's supply chain enterprises have applied innovative multi-station continuous stamping technology to produce lead screw end caps:
Production Efficiency: Production cycle time is increased to 3 seconds/piece, achieving high-efficiency mass production.
Lightweight Contribution: This technology helps reduce the overall weight of robot structural components by 30%, gaining recognition from OEMs such as Xiaomi and Unisoc.
3. Body Frame and Lightweight Structural Components
To achieve lightweight and high strength, structural components such as the main skeleton and joint connectors of humanoid robots widely use materials such as aerospace aluminum and titanium alloys. Stamping is a key process for achieving mass production of complex curved surface structural components:
Material Application: Difficult-to-machine materials such as aerospace aluminum 7075 and titanium alloy TC4 can be avoided through stamping due to the high costs and high scrap rates of traditional machining. Production Mode: Similar to automobile manufacturing, efficient and consistent mass production through the use of stamping presses and molds is one of the core paths to achieving lightweight robots.
4. Other Potential Stamped Parts
Sensor Housings: Precision housings for some force sensors and encoders, requiring high-precision thin-walled structures, may also utilize precision stamping.
Connectors and Brackets: Various mounting brackets and cable fasteners inside the robot are also mostly stamped parts.
In summary, harmonic reducer flexspline and lead screw end caps represent the most core and technologically groundbreaking applications of stamping technology in humanoid robots, while lightweight structural components such as the body frame are the foundation for achieving mass production. Stamping technology is transforming from an "auxiliary process" into a key manufacturing means driving cost reduction and efficiency improvement in humanoid robots and achieving domestic substitution.
