Flat wire automatic unloading forming machine of flat wire hairpin motor of new energy automobile

Abstract

The invention discloses a flat wire automatic unloading forming machine of a flat wire hairpin motor of a new energy automobile. An automatic wire pre-feeding mechanism, a flat wire straightening mechanism, a profiling cutter lossless enameled sheath removing mechanism, a flat wire feeding mechanism, a flat wire chamfering and primary cutting mechanism, a hairpin profiling equal-length positioning and rotary wire breaking mechanism and a hairpin profiling forming and automatic blanking mechanism are sequentially installed in the advancing direction of a flat wire. Automatic feeding, automatic straightening, automatic paint removing, chamfering, rotary wire breaking, forming and discharging of the flat wire are achieved, damage to the flat wire is small, the hairpin profiling length and shape of the flat wire are consistent, and the machining efficiency and quality of the flat wire are improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular provides a flat wire automatic off-line forming machine for a new energy automobile flat wire card-sending motor. Background technique [0002] At present, the existing flat wire automatic off-line forming machine in the market has a simple U shape, and its application range is limited to the automatic off-line forming of the U-shaped flat wire of the rotor of an ordinary motor, and the general method of removing the paint is the narrow enamelled flat wire. The side is painted by punching, and cut off together with the rounded corner size R of the flat copper wire, resulting in a large reduction in the cross-sectional area of ​​the coil. After this method is applied to the off-line forming process of the hairpin motor, the cross-sectional area of ​​the coil is reduced by about 10%. Caused a serious decline in the actual output power of the card generator; at the same time in the rapidly...

[0002] At present, the existing flat wire automatic off-line forming machine in the market has a simple U shape, and its application range is limited to the automatic off-line forming of the U-shaped flat wire of the rotor of an ordinary motor, and the general method of removing the paint is the narrow enamelled flat wire. The side is painted by punching, and cut off together with the rounded corner size R of the flat copper wire, resulting in a large reduction in the cross-sectional area of ​​the coil. After this method is applied to the off-line forming process of the hairpin motor, the cross-sectional area of ​​the coil is reduced by about 10%. Caused a serious decline in the actual output power of the card generator; at the same time in the rapidly developing field of new energy vehicles, the emergence and development of new energy vehicle flat copper wire card drive motors, its key components drive the card generator, because the coil shape of the stator winding Like issuing cards, it is necessary to design flat wires with little damage to copper wires, the imitation flat wire depainting tool system mechanism and its automation equipment, which means that it is urgent to develop new types of new energy vehicles in order to realize automated production Card-issuing motor Flat wire card-issuing automatic off-line forming machine
