AI Technical Summary
When mass production of transformer coils, manual shaping efficiency is low and cannot be batch-processed, which improves workers' labor intensity and cannot ensure the consistency of coil shaping.
A coil plastic shaping fixture is designed, including a base, support plate, light bar, pallet, positioning column, outer molding plate and inner swelling block. The cylinder pushes the moving block and inner swelling block to move, and the inner swelling block squeezes the coil on the side wall of the contour opening to complete the swelling.
Without manual plastic surgery, multiple coils can be shaped at a time, reducing workers' labor intensity, improving production efficiency, and ensuring consistency in mass production.
