Abstract
The invention relates to a cutting and molding method of a flat wire laminating coil. The key points of the cutting and molding method of the flat wire laminating coil are that a cutter blade 2 like a fruit knife is adopted for an oxygen-free copper blank 1, and a flat wire 3 is formed by rotary cutting; a cutting edge 2-1 and a thickness limit gap 2-2 are designed in the cutter blade 2; a laser cutter is used for replacing the mechanical cutter blade 2; and the parameters of a laser cutting head are adjusted by the laser cutter, so that the thickness and the cutting width of the flat wire can be controlled.
Description
Technical field
The present invention relates to the moulding process of solenoid.Particularly relate to the cutting forming method of flat conductor multilayer coil.
Background technology
The electromagnetic induction devices such as motor, transformer, inductor all need to use solenoid, the technique of conventional electromagnetic coil is all adopt round conductor coiling, this technique limits the raising of " copper factor ", the air-gap that round wire exists each other simultaneously increases the thermal resistance that coil inside is outwards dispelled the heat, these two factors seriously constrain the efficiency of electromagnetic equipment, cause the rather voluminous of these electromagnetic equipments.
Along with the cry of energy-conserving and environment-protective increases day by day, the technique of Square wire or flat conductor is adopted to arise at the historic moment.Adopt Square wire directly to substitute traditional round wire and can receive considerable benefit lifting, adopt the electromagnetic equipment of Square wire technique compared with the electromagnetic equipment of the traditional round wire technique of Same Efficieney, efficiency can improve more than 25%; Adopt the electromagnetic equipment of flat conductor multilayer coil, its efficiency can promote further on the basis of Square wire.
Up to now, flat conductor coiling multilayer coil remains the technical threshold of industry, and the present invention in a very simple way, achieves effective coiling of flat conductor multilayer coil.
Summary of the invention
Flat conductor multilayer coil involved in the present invention cutting forming method key be have employed be similar to fruit peeler bite 2 on oxygen-free copper blank 1, rotary cutting cuts out flat conductor 3; Bite 2 is designed with cutting edge 2-1 and thickness restriction gap 2-2; Laser cutter can be adopted to substitute machine cut cutter 2, and laser cutter, by the parameter of adjustment laser cutting head, just can control thickness and the cutting width of flat conductor.
Bite 2 is relatively-stationary, and oxygen-free copper blank 1 rotates centered by bite 2; The cutting edge 2-1 of bite 2 adopts one or more synthesis in high-carbon steel, high-speed steel, non-cast-iron alloy steel, sintered carbon formed material, ceramic material, boron oxide material to make; Thickness restriction gap 2-2 limits flat conductor 3 thickness, and its operation principle is similar to fruit peeler.
The stock-removing machine of machining flat wire must be Digit Control Machine Tool, and this Digit Control Machine Tool at least has the controlling functions of more than 3 axles: oxygen-free copper blank 1 may need X-Y direction to move while bite 2 rotates, and bite 2 needs to move along Z-direction; If oxygen-free copper blank 1 is complex-shaped shaped piece, then in working angles, oxygen-free copper blank 1 also may need rotation.
The oxygen-free copper blank 1 that carries out processing must be hollow, and the shape of oxygen-free copper blank 1 is corresponding with the shape of the flat wire coil after machining.
Machining just completes technique oxygen-free copper blank being processed into flat conductor, when flat conductor is used as coil use, also has to pass through insulation processing.Such as: the methods such as insulation paint immersion coating, interlayer cushioning insulating materials (mica sheet, insulating paper), winding empire silk/paper.
