Embodiment Construction

[0028] The armature coil lead head is limited in width and flattened. It includes an upper die 1 and a lower die 2. A rib 3 is provided on the stamping end face of the upper die 1, and a rib 3 is formed on the stamping end face of the lower die 2 to match the stamping end face of the upper die. The protruding rib 3 fits with the groove 4 whose width is equal to the designed width of the armature coil lead head. In order to better realize the connection and fixation of the upper mold, the lower mold and the punching machine, a screw hole is opened on the top of the upper mold 1, and the upper mold handle 5 is fixed in the screw hole, and the upper mold and the punching machine can be connected through the upper mold handle 5. Fixed; screw holes are provided at the bottom of the lower die 2, and a base plate 6 is fixed at the bottom of the lower die. The two ends of the base plate 6 are provided with grooves for fixing with the punch press. The lower die is placed on the punch pr...

Abstract

The related limit-width flattened forming mould for armature coil lead riser as motor production equipment comprises: an upper module with ribs on its stamping end surface, and a lower mould with grooves on its stamping end surface that matches with the rib and has width same as the required riser width. This invention just forms in one piece, reduces cost greatly, improves product quality as even thickness and smooth surface.

Description

technical field [0001] The invention relates to motor production equipment, in particular to a width-limiting and flattening molding die for lead ends of armature coils. Background technique [0002] The armature coil is the core component of the motor. The armature coil lead head is one of the key parts of the entire armature coil. It is connected with the commutator rising plate and plays the role of current conduction and commutation. It can reduce the commutation spark, reduce the contact loss with the rising plate, reduce the temperature rise of the lead end, reduce the insulation aging, and improve the operating life of the coil. [0003] At present, one of the conventional methods for forming the armature coil lead is to flatten the lead. After rolling, the thickness of the lead is uneven and the shape is tapered. Contact, resulting in increased contact resistance, excessive local temperature rise at the coil lead end, accelerated insulation aging, increased probabil...
