[0065] In order to further improve the winding quality, such as Figure 16-18 As shown, the device also includes a heating system that can respectively heat the coiled wire a coiled on the winding jig 13 and the two ends of the coiled wire a. Specifically, the heating system here includes a heating system that is arranged on the main shaft 21 and can be continuously coiled to the winding jig 13 when one end of the coiled wire a is rotated along the circumference of the winding jig 13 to be wound on the winding jig 13 The rotary preheating mechanism 5 on the tool 13 for real-time heating of the coiled wire a is an optimized solution. The rotary preheating mechanism 5 here includes a rear ring end sleeved on the main shaft 21 and rotationally connected to the main shaft 21 The cover 51 is also sleeved on the main shaft 21 with a front annular end cover 52 which is movably and sealedly connected with the rear annular end cover 51 in a circumferential direction, and an annular air groove 53 is provided between the rear annular end cover 51 and the front annular end cover 52, An air inlet 51a communicating with the annular air groove 53 is provided on the rear annular end cover 51, an air outlet 52a communicating with the annular air groove 53 is provided on the front annular end cover 52, and an outlet pipe is connected to the air outlet 52a 52b.

An air guiding pipe 64 is connected between the hot air generator and the exhaust pipe, and the inner diameter of the air guiding pipe is larger than the inner diameter of the exhaust pipe. When the clamping and breaking device 42d is lowered to the preset height, the thread end of the coiled wire is taken and then lifted to the set height. When the winding jig 13 is continuously wound and the clamped breaking device 42d is raised When one end of the coiled wire is used, the exhaust duct 62 is aligned with the raised end of the coiled wire.

[0067] In addition, such as Figure 20 As shown, the mounting base 2 is also provided with a heating device 7 capable of heating the coiled wire a coiled on the winding jig 13. The heating device 7 includes an air supply pipe 71 which is connected to a hot air source. The air supply pipe 71 is provided on a lifting rod 72 arranged horizontally.

[0068] Because the rotary preheating mechanism is installed, the coiled wire rotating along the circumferential direction of the winding jig can be heated in real time (synchronous rotation), and the other end of the coiled wire can be heated in real time due to the preheating device. Since the heating device is set to heat the coiled wire wound on the winding jig in real time, preheating not only shortens the heating time, but also improves the heating effect, making the heating more uniform, and also improves the product The processing quality and the stability of later use further improve the practicability of the winding machine, which is in line with the current development trend of social technology. Secondly, if there is no preheating, the temperature of the winding fixture is higher than the heating temperature of the coiled wire during the winding operation of the winding equipment, and the addition of the heating system of this embodiment can reduce the winding fixture Temperature, thereby prolonging the service life of the winding jig. At the same time, compared with only one heating (the total current output by the multi-axis is higher and the temperature is higher), the addition of the heating system of this embodiment can reduce the total temperature, that is The power is reduced, and the design is more humanized.

[0069] Further, as figure 1 As shown, in order to improve the degree of machine automation and the production efficiency of the machine, the mounting base 2 is provided with a reclaiming mechanism 8 that can obtain the hollow coil from the winding jig 13 when the winding is completed; specifically, the reclaiming mechanism 8 includes a reclaiming rod 81 arranged on the mounting seat, and a plurality of reclaiming rods 81a corresponding to the winding jig are provided on the reclaiming rod 81, and the reclaiming rod 81 is set on the reclaiming rod.

[0070] Such as Picture 9 As shown, the clamping and breaking device 42d includes a clamping sleeve 426. One end of the clamping sleeve 426 is provided with a static positioning surface 427. The clamping sleeve 426 is provided with a static positioning surface or a distance away from the static positioning surface so as to be The coiled wire clamps or releases the dynamic pressure portion 428 of the coiled wire. The dynamic pressure portion is also provided with a cutter 429 that can cut the wire synchronously when the wire is clamped. The dynamic pressure portion and the driving dynamic pressure The clamping and disconnecting cylinders 430 close to the static positioning surface or away from the static positioning surface are connected. The clamping and breaking cylinder 430 is connected to the dynamic pressure part 428 through the jack 431 inserted in the clamping sleeve 426.

[0071] The working principle of this embodiment is as follows: when the clamping and breaking device 42d pulls the coiled wire a, the spool unit 11 releases the wire, and the coiled wire sequentially passes through the tensioner and the thread guide seat 2a into the passing of the main shaft 21 The wire passes and is output from the fly fork arm, and then the translation seat 32 is driven by the drive shaft 31 to make the secondary shaft 23 close to the main shaft 21 and make the female core mold of the winding jig 13 cooperate with the male core mold, and then The drive shaft 31 rotates radially and drives the secondary shaft 23 to drive the winding jig 13 to rotate. At the same time, the main shaft drive mechanism 22 drives the main shaft to rotate so that the middle part of the coiled wire is pre-wound on the winding jig 13. During the winding process , The coiled wire is heated by the rotary preheating mechanism 5, the preheating device 6 and the heating device 7.

[0072] When the first winding is completed, the coiled wire material is cut by the clamping and breaking device 42d and the end of the next winding wire is clamped, and then the auxiliary shaft 23 is moved away from the main shaft 21 under the axial drive of the drive shaft 31 Thus, the female core mold and the male core mold are separated, the wound hollow coil is removed by the material taking mechanism 8, and the above steps are repeated to enter the next winding.
