Abstract
The invention relates to a joint process method of an aluminium wire motor. The method comprises the following steps that: firstly, lead-out wires of aluminium wires and copper wires are welded by using a soldering tin and scaling powder process of a common copper wire motor; secondly, the welded joint is immersed to hot melt adhesive at a temperature of between 100 and 120 DEG C for about 45 to 70 seconds in order that the hot melt adhesive and the joint are fully combined together, thereby achieving the insulation between the joint and the outside and strengthening the tight connection between the aluminium wires and copper wires; thirdly, a thermal shrinkage sleeve which can resist a temperature between 130 and 170 DEG C is arranged on the outside for fixing and molding the joint; fourthly, the joint is heated for 80 to 100 seconds to be fixed and molded. The method uses the process of the joint with colloid and the thermal shrinkage sleeve, adopts the mode of first heating melt adhesive and then the thermal shrinkage sleeve, is convenient to operate and uneasy to break the wire and can be applied to the manufacturing of small-scale aluminium wire motors.
Description
Technical field
The invention belongs to machine field, relate to electric machine joint, especially little line footpath electric machine with aluminium winding joint manufacturing process.
Background technology
The joint technology of using on the electric machine with aluminium winding at present mostly adopts rolls the processing mode that connects, and is applied to the situation of high-power, big line footpath aluminum steel; For little line footpath electric machine with aluminium winding, roll the processing mode that connects in the technology drilling difficulty of making comparisons, and joint ruptures easily, exist simultaneously to combine untight shortcoming.
Aluminum steel and copper cash belong to different material, can't melt mutually in liquid condition.Utilize the technology of welding in the past, scolding tin can't make two kinds of materials combine.And aluminium generates oxide layer, the obstruction welding easily because oxidizing temperature is lower on the surface.Utilize to roll in the prior art to connect principle, use is rolled sheet copper cash and aluminum steel is pressed together, and plays purpose of connecting.As shown in Figure 1, comprising aluminum steel 3, roll sheet 6, copper cash lead-out wire 5, copper cash 4, adopt in the place of enamelled wire that connects motor and lead-out wire and to roll sheet 6 and roll to fetch and is connected copper cash 4 and the aluminum steel 3 that script is difficult to link together; This copper aluminium connects technology, on the electric machine with aluminium winding in big line footpath, uses comparatively convenient and swiftly, occurs short-term easily but on little line footpath, use, and connects closely and scratches the phenomenon of paint film, thereby cause reducing motor useful life.
Summary of the invention
The object of the present invention is to provide a kind of piecer's process of novel motor, simplify the operation, reduce the joint breaking incidence, enough improve the reliability of electric machine with aluminium winding.
For achieving the above object, solution of the present invention is:
Piecer's process of electric machine with aluminium winding may further comprise the steps:
A. employed aluminum steel and copper cash are welded;
B. the aluminum steel that obtains welding and the joint of copper cash immerse in the PUR, wrap the welding position of aluminum steel and copper cash with PUR;
C. add the heat-resisting heat-shrinkable T bush of one deck in the PUR outside, with fixedly moulding of joint, said heat-shrinkable T bush is semiclosed, is inserted in by the plumb joint top.
Further, be that joint is immersed in 100 ℃～120 ℃ PURs among the step B, accomplished through 45 seconds～70 seconds.
Added in the PUR outside among the step C is heat-resisting 130 ℃～170 ℃ heat-shrinkable T bush, heats completion in 80 seconds～100 seconds afterwards again.
Be that joint is immersed in 120 ℃ of PURs among the step B, accomplished through 45 seconds.
Added in the PUR outside among the step C is heat-resisting 150 ℃ heat-shrinkable T bush, and heat-shrinkable T bush length is longer than PUR partly for 1.5cm arrives 2cm, reaches the effect of parcel PUR and plumb joint, heats completion in 90 seconds afterwards again.
Or, be that joint is immersed in 120 ℃ of PURs among the step B, accomplished through 45 seconds; And added in the PUR outside among the step C is heat-resisting 150 ℃ heat-shrinkable T bush, heats completion in 90 seconds afterwards again.
Use has the joint technology of colloid and heat-shrinkable T bush, adopts to add the mode that PUR adds heat-shrinkable T bush more earlier, and handled easily is difficult for broken string, can be applicable to the manufacturing of small-sized electric machine with aluminium winding.
Description of drawings
Fig. 1 is that prior art adopts in joint technology and rolls the processing mode sketch map that connects.
Fig. 2 is the processing mode sketch map of a kind of embodiment of process of the present invention.
Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the present invention is further described.
See also Fig. 2, comprising PUR 1, heat-shrinkable T bush 2, aluminum steel enamelled wire 3, copper cash 4, lead-out wire 5; The aluminum steel joint welding procedure that has PUR mainly may further comprise the steps:
1, employed aluminum steel enamelled wire 3 and copper cash 4 are welded (this technology and existing common process are basic identical);
2, immerse the joint of aluminum steel enamelled wire 3 and copper cash 4 in 100 ℃～120 ℃ PURs 1,, wrap the welding position of aluminum steel enamelled wire 3 and copper cash 4 with PUR 1 through about 45 seconds～70 seconds;
3, (heat-shrinkable T bush is semiclosed to add heat-resisting 130 ℃～70 ℃ heat-shrinkable T bush of one deck then in PUR 1 outside; Can be inserted in by the plumb joint top); Heat-shrinkable T bush length is longer than PUR and is partly arrived 2cm for 1.5cm; Reach the effect of parcel PUR and plumb joint, and then heated 80 seconds～100 seconds, with fixedly moulding of joint.
