Description
Technical Field
The invention relates to the field of dies, in particular to a paint removing die for flat copper wire elements of various motor armatures.
Background
Currently, known motor armature elements are divided into round copper wires and flat copper wires, wherein the round copper wires are small in sectional area, convenient to process and good in process molding, and are used for low-power motor armatures; the flat copper wire has larger sectional area, which causes difficulty for processing and process molding, and is mostly used for high-power motor armatures. When meeting the market demand of high-power motors and researching, developing and manufacturing the motors, flat copper wires with relatively large sections are mostly adopted as motor armature elements. When the narrow-side paint skin removing die carries out narrow-side paint skin removing on the flat copper wire, on one hand, the distance between the inner side knife and the outer side knife of the upper paint skin removing knife can be increased and deformed outwards rapidly in the use process, and the fit clearance between the upper paint skin removing knife and the lower paint skin removing knife is increased, so that burrs at four edges and corners of an armature element of the motor are large after paint skin removing is finished, and the armature slot insulation can be punctured by overlarge burrs of the element, so that armature breakdown short circuit is caused. Therefore, the service life of the cutter of the existing narrow-edge paint coat removing die is short; on the other hand, after the armature element is bent P-shaped, there are the following problems: 1. the overlap joint of the inner layer element and the outer layer element causes armature short circuit fault; 2. during brazing, the welding head is pressed to the surface of the paint skin for welding, so that the welding quality and the armature conductivity are poor, and the armature quality is seriously affected.
