AI Technical Summary
Existing technologies cannot effectively process spherical surfaces on workpieces, resulting in low processing efficiency and high labor costs, which cannot meet the needs of automated production.
A spherical wire drawing device was designed, including a worktable, a wire drawing mechanism, a contouring pressure block, and a support. The device automatically performs wire drawing on the spherical surface of the workpiece through the reciprocating swing motion of the swing arm and the cooperation of the abrasive belt. The abrasive belt is pressed by the contouring pressure block with the shape matching the spherical surface of the workpiece. The wire drawing effect is improved by the combination of dynamic abrasive belt and swing motion.
It achieves efficient and automated wire drawing of spherical workpieces, improves processing uniformity and adaptability, reduces labor costs, avoids wear and uneven pressure problems of traditional equipment, and is suitable for processing complex curved surfaces.
