Flexible Adaptation in UAV Micro Screws Overcomes the Pain Points of Complex Curved Surfaces and Thin-Wall Forming
2026,03,12
For thin-walled metal parts (such as electronic device housings and lightweight aerospace components) and parts with complex curved surfaces, traditional rigid
UAV Micro Screws are prone to localized wrinkling, cracking, or uneven deformation.
Innovative design introduces the concept of "flexible forming," achieving uniform material deformation through structural and media innovation.
Partial edge clamping technology is a typical example: the edge clamping ring of an UAV
Micro Screws is divided into multiple independently controlled areas, and the clamping force in each area can be individually adjusted via hydraulic or pneumatic systems.
For example, in the stretching of stainless steel water tanks, the deformation requirements of the bottom and sidewalls differ. Partial edge clamping can apply a larger clamping force to the sidewalls to prevent wrinkling, and reduce the clamping force to the bottom to avoid cracking, increasing the forming pass rate from 70% to over 95%.
Furthermore, flexible media forming technologies (such as rubber stretching and hydraulic stretching) replace rigid punches/dies with elastic materials or liquids, allowing the material to gradually conform to the UAV Micro Screws profile under uniform pressure, effectively solving the forming challenges of thin-walled parts (thickness ≤ 0.5mm).
For example, in the electronics industry, aluminum alloy mobile phone frames, after adopting hydraulic UAV Micro Screws, have no scratches on the surface of the parts, and the wall thickness deviation is controlled within ±0.02mm, meeting the precision requirements of high-end products.
