Description
Technical field
The present invention relates to the moulding process of electromagnetic coil.More particularly to the cutting forming method of flat conductor multilayer coil.
Background technology
The electromagnetic induction devices such as motor, transformer, inductor are required for using electromagnetic coil, the work of conventional electromagnetic coil
Skill is all using round conductor coiling, and this technique limits the raising of " copper factor ", while round wire is existing between each other
The thermal resistance that the coil inside that air-gap increases radiates outward, the two factors seriously constrain the efficiency of electromagnetic equipment, lead to this
The rather voluminous of a little electromagnetic equipments.
As energy-saving and environment-friendly cry increasingly increases, come into being using the technique of Square wire or flat conductor.Using side
Conducting wire, which directly substitutes traditional round wire and can receive considerable benefit, to be promoted, using Square wire technique electromagnetic equipment with
The electromagnetic equipment of traditional round wire technique of Same Efficieney is compared, and efficiency can improve more than 25%；It is laminated using flat conductor
The electromagnetic equipment of coil, efficiency can further be promoted on the basis of Square wire.
So far, flat conductor coiling multilayer coil is still the technical threshold of industry, and the present invention is with very simple
Method realizes effective coiling of flat conductor multilayer coil.
Invention content
The cutting forming method key of flat conductor multilayer coil according to the present invention is to employ similar to pericarp
For the bite 2 of knife on oxygen-free copper blank 1, rotary cutting cuts out flat conductor 3；Cutting edge 2-1 and thickness are designed on bite 2
Degree limitation gap 2-2；Laser cutter may be used and substitute machine cut knife 2, laser cutter is by adjusting laser cutting head
Parameter, it is possible to control the thickness and cutting width of flat conductor.
Bite 2 is relatively-stationary, and oxygen-free copper blank 1 is rotated centered on bite 2；The cutting edge 2-1 of bite 2
Using one or more of high-carbon steel, high-speed steel, non-cast-iron alloy steel, sintering char-forming material, ceramic material, boron oxide material
Synthesis makes；Thickness limitation gap 2-2 limits flat conductor 3 and sends out thickness, and operation principle is similar to fruit peeler.
The stock-removing machine of machining flat conducting wire must be numerically-controlled machine tool, which at least has control more than 3 axis
Function：Oxygen-free copper blank 1 around bite 2 rotate while X-Y directions may be needed to move, bite 2 needs to move along Z-direction
It is dynamic；If oxygen-free copper blank 1 is complex-shaped shaped piece, oxygen-free copper blank 1 it may also be desirable to rotation in working angles.
The oxygen-free copper blank 1 being processed must be hollow, and after the shape and machining of oxygen-free copper blank 1
The shape of flat wire coil is corresponding.
Turning deformation limiter is mounted on the outside of upper pressing disc, and upper pressing disc has identical outer diameter, turning deformation limit
It is closely slidably matched between device processed and upper pressing disc, the outside expansion change in outer when can limit flat conductor turning well
Shape.
It is different according to the shape of flatwise coil, pressing disc in adaptable difference is designed, flat conductor after molding is laminated
The shape of coil is corresponding with the shape of upper pressing disc；Replace different upper pressing discs, it is possible to obtain of different shapes flat
Conducting wire stack coil.These coils can be circular ring shape, ellipse, fillet strip, tapered trapezoidal or Else Rule
Geometry.
Machining is the technique for completing and oxygen-free copper blank being processed into flat conductor, and flat conductor makes as coil
Used time, it is necessary to by insulation processing.Such as：Insulation paint immersion coating, interlayer cushioning insulating materials (mica sheet, insulating paper), winding
The methods of empire silk/paper.
