Embodiment

Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.

With reference to shown in Fig. 1 and Fig. 2, a kind of winding former opened that contracts in the present embodiment, including die sleeve 1 and the die sleeve 1 The overcoat 2 that is engaged, it is arranged at the springform core assembly in cavity between the die sleeve 1 and the overcoat 2, the elastic core rod Component includes the elastic core rod 3, the work mould 4 being flexibly connected with the overcoat 2, setting being slidably connected with one end of the die sleeve 1 It is used for the internal model 5 of the folding of mould 4 living, the first of the lateral wall of internal model 5 between the elastic core rod 3 and the mould living 4 Inclined plane 51 and the second inclined plane 41 of the madial wall of mould 4 living are slidably matched, the end face of the internal model 5 and the iron core 9 of stator Side wall is engaged；

When the iron core 9 promotes the internal model 5 to move backward under coil winding machine effect, the of the lateral wall of internal model 5 Second inclined plane 41 of one inclined plane 51 along the madial wall of mould 4 living is moved backward, and the front port for mould 4 of now living shrinks；Work as institute Iron core 9 is stated when being travelled forward under coil winding machine is acted on away from the internal model 5, the edge of the first inclined plane 51 of the lateral wall of internal model 5 Second inclined plane 41 of the madial wall of mould living 4 travels forward, and the front port for mould 4 of now living opens.

Specifically, in the present embodiment, the mould 4 living is formed by 2 mould combination of monomers living.The internal model 5 is tapered to be set, And the lateral wall of the internal model 5 is provided with guide rib along the length direction of internal model 5.The madial wall of the mould living 4 is provided with and institute The chute that guide rib is engaged is stated, the guide rod 6 that the mould 4 living is worn with the overcoat 2 by radial direction is connected, and the work The end of the work mould monomer of mould 4 is slided along the guide rod 6 and set, and the two side of the overcoat 2 is provided with for limiting the bullet Property the stroke of core rod 3 limited screw 7, the elastic core rod 3 includes core rod 32 and is arranged at the die sleeve 1 and the core rod 32 Between spring 32.

Using said structure design winding former, one end of die sleeve 1 is fixed on the rolling of hollow windings' axle front end of coil winding machine On bearing, when roll rotates, roll is not followed to rotate using the buffer action die sleeve 1 of rolling bearing；Die sleeve 1 it is another End is equipped with core rod, and the external diameter of core rod coordinates with the interior interporal lacuna of die sleeve 1, and spring is housed between die sleeve 1 and core rod, spring is utilized Elastic force makes the power that core rod keeps one to eject outward, and limited screw 7, which is mounted on die sleeve 1 and stretches out a part, is stuck in core rod side In groove, will not be rotated when core rod is slided in the die sleeve 1, at the same be also prevented from core rod by the power of spring out of die sleeve 1 completely Ejection；Guide rod 6 has two, in cylinder, is fixedly mounted in two circular holes symmetrical above and below of external mold 2；The shape of internal model 5 is carried Two symmetrical slopes for being engaged with the coiling angle of the v-groove of stator core 9 or rotor core 9, two inclined-planes have two groups it is symmetrical Guide rib；External mold is fixed on die sleeve 1, and internal model 5 is fixed on core rod, and mould 4 living has symmetrical two valve, and each valve has two Tip chute is slidably matched with a pair of guide ribs in internal model 5, and symmetrically mould living respectively has a circular arc to lead in both sides to two valves about 4 Matched to groove with two guide rods 6 being fixed on external mold.When coil winding machine does not carry out coiling to stator core 9 or rotor core 9 When, a winding former that can contract keeps certain intervals distance with iron core 9, and the internal model 5 being connected on core rod is pushed out by the power of spring Go out, with reference to the guide effect for two circular guide rods 6 being fixed on external mold, two valves are promoted respectively by two groups of symmetrical guide rails Mould 4 living is expanded outwardly, so that the front end face of mould 4 living aligns the opening of iron core 9.After coiling action starts, the feeding of coil winding machine Mechanism driving winding former is close to stator core 9 or rotor core 9, when internal model 5 is put off till with iron core 9, and spring stress compression is interior It is in relative motion between the valve of mould 5 and two work mould 4, with reference to the guide effect for two circular guide rods 6 being fixed on external mold, passes through two The symmetrical guide rail of group pulls two valves to live mould 4 constantly to contract respectively.The amplitude of contraction just with stator core 9 or rotor iron The angle of the winding slot of core 9 is consistent.A winding former can be contracted in stator core 9 or rotor core 9 when coil winding machine feed mechanism drives Winding slot on come and go winding displacement when, two valves live mould 4 in the angle being consistent with coiling notch reclaim contracting or expand.Mould 4 living Front end face enamel-covered wire be closely oriented to be aligned on the correct position of stator core 9 or rotor core 9, with this so that winding displacement It is more uniform smooth.
