Description
Technical field
The present invention relates to the manufacture field of some special dimensions, particularly hollow-cup motor such as Aeronautics and Astronautics, weapons, medicine equipment, robot.
Background technology
On powerful hollow-cup motor, because air gap is limited, on hollow cup coil cup is made, need to adopt multilayer winding to realize at present, the coil cup of external similar motor is all realized by fully-automatic equipment Double-wire parallel wound.Because this powerful hollow-cup motor is mainly used in military industry, domestic also do not have this equipment of company's independent research at present, common way is two hollow cup coils that vary in size of coiling, the external diameter of small coil is identical with the internal diameter of large coil, so large coil is nested together into a cup with small coil, but this hollow cup coil cup thickness is larger, the motor key technical index electro mechanic time constant producing, power of motor density etc. cannot reach same kind of products at abroad technical merit.
Summary of the invention
The present invention seeks to design a kind of forming method and die for special purpose of multilayer hollow-cup motor winding.
The forming method of multilayer hollow-cup motor winding, it is to implement in accordance with the following steps:
1 coiling: the rhombus winding former that is shaped with the flexible line of rabbet joint on coil winding machine in the middle of putting, described winding former one end is fixed on coil winding machine, the other end is plug beyond the Great Wall, on winding former around complete the first layer line, the first not demoulding, after making zero, coil winding machine again around the second layer, around complete, with high temperature gummed tape, fixes afterwards the then demoulding;
2 coil hot pressing are flat: line mould is carried out to shaping, push over, hot pressing, the shaped as frame limiting tool of putting into opening after coil hot pressing is for the first time flat flattens again, guarantee that coiling do not extend to two ends, and guarantee that the requirement for height of drag cup cup is 51
0 + 0.1mm;
3 volume circles: with putting into row volume circle by the volume sired results with volume circular shaft again after the spacing pressing sizing of described limiting tool;
4 school circle sizings: finally with circular knitting machine school, hot school circle, brush coating sizing.
Realize the die for special purpose of described multilayer hollow-cup motor winding forming method, it comprises winding former, limiting tool and volume sired results dress, and described winding former is the outside roll for rhombus, middle hollow, on roll, be axially shaped with the flexible line of rabbet joint being arranged symmetrically with, roll one end is installation shaft, and one end is plug hole in addition; Limiting tool is the limitting casing of an opening, and on limitting casing, is shaped with the line outlet groove being evenly arranged; The harness of volume sired results has volume circular shaft, and volume round sleeve, on handle, is rolled up on the circumference of circular shaft one end simultaneously and is shaped with volume circular shaft line outlet groove, and locate by nut and handle volume other one end of circular shaft.
The invention solves the problem of the moulding difficulty of multilayer hollow-cup motor winding; After adopting the method coiling hollow cup coil assembling motor, its key technical index can reach external similar motor product technical merit.

Embodiment
On original coil winding machine, designed a set of winding former, seen shown in Fig. 1-1--Fig. 1-4.Installation shaft 1-1 one end of winding former is fixed on coil winding machine, and plug beyond the Great Wall in other end plug hole 1-3 prevents that coil winding machine from driving winding former to rotate, and in coiling process, winding former shrinks.On winding former, around complete the first layer line, the first not demoulding, again around the second layer, fixes the then demoulding after coil winding machine makes zero afterwards with high temperature gummed tape around complete.During the demoulding, first remove plug, plug hole outer wall firmly, shrinks plug hole, slowly moves back wire finishing die, and line mould is carried out to shaping, pushes over, hot pressing.Coil hot pressing is flat.Installation shaft effect is that winding former is fixed on coil winding machine, and elastic force hole makes to shrink elasticity on roll and strengthens.Roll is used for coil around axle.Plug stopple upper plug head makes the not contraction distortion of winding former coiling process.
Line mould after hot pressing is put into limiting tool (as shown in Fig. 2-1--Fig. 2-3) and is again flattened, and corresponding spindle nose is drawn from line outlet groove, guarantees to wind the line and to two ends, does not extend, and line mould is put into limitting casing, thereby guarantee that the requirement for height of drag cup cup is 51
0 + 0.1mm, flattens in limitting casing with four directions rod.With rolling up circle with volume sired results dress (seeing shown in Fig. 3-1--Fig. 3-2) again after the spacing pressing sizing of limiting tool.Volume bowlder is through line mould on volume circular shaft and rolls up circle, with high temperature gummed tape, fixes, and corresponding coil tap is drawn from line outlet groove, and nut is screwed on handle and locates, and holds handle, then the round as a ball pressing backed off after random of coil coil.Finally, with circular knitting machine school, hot school circle, brush coating is shaped.
The die for special purpose of realizing said method comprises winding former, limiting tool and volume sired results dress, and described winding former is the outside roll 1-5 for rhombus, middle hollow, on roll 1-5, be axially shaped with the flexible line of rabbet joint 1-4 being arranged symmetrically with, roll 1-5 one end is installation shaft 1-1, and one end is plug hole 1-3 in addition; The roll 1-5 of described winding former is positioned at mono-of installation shaft 1-1 and is also shaped with elastic force hole 1-2.Limiting tool is the limitting casing 1-1 of an opening, and on limitting casing 1-1, is shaped with the line outlet groove 1-2 being evenly arranged.The harness of volume sired results has volume circular shaft 3-3, and it is upper that volume circular shaft 3-3 is enclosed within handle 3-1, rolls up on the circumference of circular shaft 3-3 one end simultaneously and is shaped with volume circular shaft line outlet groove 3-2, and locate by nut 3-4 and handle 3-1 volume other one end of circular shaft 3-3.
