Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, and in particular relates to a 3D bending machine for motor hairpin flat wires. Background Art

[0002] The motor hairpin flat wire 3D bending machine is a special equipment used to process stator winding copper wire in the manufacturing of flat wire motors with high full slot rate. In the motor industry, hairpin flat wire (also known as shape winding) refers to electromagnetic wire that has been pre-formed. Its shape is similar to a hairpin and is used to make motor stator coils. The main function of the equipment is to accurately bend flat copper wire so that it can conform to specific three-dimensional geometric shapes. These shapes are designed according to the specific requirements of the winding slots in the motor design. However, the current bending machines cannot provide bending in multiple directions during use, and have certain limitations in work. In some specific application fields that require three-dimensional angle bending, it cannot meet production requirements. In order to meet the multi-angle three-dimensional cable bending, it is particularly necessary to study the motor hairpin flat wire 3D bending machine. Utility Model Content
