Title:
FLAT-WIRE BENDING APPARATUS FOR FLAT-WIRE MOTOR WINDING
Document Type and Number:
WIPO Patent Application WO/2020/140504
Kind Code:
A1
Abstract:
A flat-wire bending apparatus for a flat-wire motor winding is capable of bending flat wires of different bending angles and bending lengths in a winding layer at one time, and prevents the flat wires from deforming in thickness directions thereof. The apparatus comprises rotary sleeves (11, 21) and a driving apparatus. A flat-wire I holding slot (2131) is provided at the outer periphery of the rotary sleeves (11, 21). Each pair of flat-wire I holding slots (1131, 2131) is oppositely disposed at end portions of part or all of the flat wires. When the rotary sleeve is moved axially towards an end portion of an iron core, end portions of the flat-wire I extend into the oppositely disposed flat-wire I holding slots. When the rotary sleeves (11, 21) rotate, the flat-wire I bends in a circumferential direction of the iron core. The outer periphery of flat wires on the same circumference is surrounded by guide sleeves (12, 22). The outer periphery of the guide sleeves (12, 22) contacts outer sides of the flat wires in a radial direction so as to prevent the flat wires from deforming outwards in a radial direction of the stator iron core during bending of the flat wires. Position-limiting sections (112, 212) are connected to holding sections (113, 213). The outer periphery of the position-limiting sections (112, 212) contacts inner sides of the flat wires in the radial direction so as to prevent the flat wires from deforming inwards in the radial direction of the stator iron core during the bending of the flat wires.
