Connect, two kinds of Joining Technologies of rivet, but regardless of technique, multiple working procedure is divided equally in its processing to be carried out.
For welding procedure, exactly by a string of helical form punchings by labeled slots position screw in weld mold in and pressed
Tightly, then welded in the punching external diameter side welding groove being superimposed, it is fixed in welding process because the temperature welded is higher
Son（Or rotor）Meeting fever expansion, but because solder is different from the material of punching, both coefficients of expansion are also inconsistent, also can once in a while
The problems such as disconnected weldering, solder skip occur to it, it is necessary to carry out repair welding or spot welding.Furthermore, the welding high temperature melt region of rotor is led
Magnetic can be affected, so as to influence the performance of rotor to a certain extent.In addition, welding needs substantial amounts of electricity consumption and welding
Material, it is relatively costly, and waste gas can be produced environment is polluted in welding process.
And in rivet interlacement, exactly the position screw-in riveting die set by a string of helical form punchings by labeled slots and pressed
Tightly, then insert rivet respectively in rivet hole site to be riveted again, whole manufacturing procedure is more complicated, operation is bothered very much,
And the rivet hole of rotor can also block the magnetic conduction in the region, so as to influence rotor performance.
Either welding or riveting, can only all be fixedly connected the cylindrical side of rotor or yoke portion, and in rotor groove, tooth
Position is easily tilted, stacking factor is low, and motor performance and noise can be had undesirable effect.
The content of the invention
Regarding to the issue above, the invention provides a kind of automobile current generator winding self bonding stator and rotor iron core, the letter of its structure
Single, manufacturing procedure is few, good connecting effect, low cost, and the performance of stator and rotor iron core will not be impacted.
The technical scheme is that a kind of automobile current generator winding self bonding stator and rotor iron core, including continuous winding
Helical form stator and rotor punching, the stator and rotor punching overlaps superposition up and down, leads between the adjacent stator and rotor punching of upper and lower two-layer
Adhesive is crossed to be connected.
Preferably, described adhesive is epobond epoxyn.
Processing technology of the invention is as follows：Stator and rotor punching is first struck out into continuous jagged length by stamping die
Bar silicon steel sheet, the setting buffers adhesive supply unit after stamping procedure, before rolling step, the stator and rotor after punching press
Adhesive can be uniformly adhered on silicon steel sheet when punching is by adhesive supply unit, and silicon steel sheet is placed on folded after the completion of winding
Pressure is overlapped in compression mould, adhesive solidifies after silicon steel sheet stack is affixed by pressure, so that the stator and rotor for forming a densification are whole
Body.
Process equipment of the invention includes pressing part, adhesive supply unit, winder and laminates portion, and described adhesive is supplied
Portion surface offers the horizontal gum outlet corresponding to stator and rotor punching yoke portion and the longitudinal plastic emitting corresponding to rotor punching teeth portion
Mouthful, the horizontal gum outlet is laterally equally spaced along adhesive supply unit, and longitudinal gum outlet has multigroup, and same group along viscous
Mixture supply unit is longitudinally equally spaced, and is laterally equally spaced along adhesive supply unit between different groups, and adjacent sets longitudinally go out
Lateral separation between glue mouthful is equal to the distance between stator and rotor punching two adjacent teeth pole center, two neighboring horizontal gum outlet
The distance between be equal to the distance between stator and rotor punching two adjacent teeth groove center.
Simple structure of the present invention, manufacturing procedure is few, good connecting effect, low cost, and will not be to the performance of stator and rotor iron core
Impact, reach motor reduction noise, put forward high performance effect.
