Figure 2 : is a schematic diagram of the exploded structure of the flat wire motor twisting device in the embodiment of the utility model. This embodiment provides a flat wire motor twisting device, including:

[0029] Base 100;

[0030] Internal twist head mold 200;

[0031] The outer twist head mold 300 is for the inner twist head mold 200 to be inserted into;

[0032] The driving member 400 is rotatably connected to the base 100. The inner twisting head mold 200 and the outer twisting head mold 300 are both detachably mounted and coaxially arranged on the driving member 400. The axis of the inner twisting head mold 200 and the outer twisting head mold 300 is the rotation axis of the driving member 400.

[0034] The locking assembly and the base 100 are enclosed to form a chamber 110 , and the inner twisting head mold 200 , the outer twisting head mold 300 and the driving member 400 are at least partially axially confined in the chamber 200 .

[0035] Since the outer twisting head mold 300 is inserted into the inner twisting head mold 200, the driving member 400 is rotatably connected to the base 100, the inner twisting head mold 200 and the outer twisting head mold 300 can be detachably installed and coaxially arranged on the driving member 400, and the axis of the inner twisting head mold 200 and the outer twisting head mold 300 is the rotation axis of the driving member 400, therefore, the radial gap between the inner twisting head mold 200 and the outer twisting head mold 300 is uniform, and the inner twisting head mold 200 and the outer twisting head mold 300 can rotate synchronously, so when the flat wire of the flat wire motor is inserted into the radial gap between the inner twisting head mold 200 and the outer twisting head mold 300 Afterwards, the flat wire can be driven to twist by synchronously rotating the inner twisting head mold 200 and the outer twisting head mold 300; since the locking assembly is detachably connected to the base 100, the locking assembly and the base 100 enclose a chamber 110, and the inner twisting head mold 200, the outer twisting head mold 300 and the driving member 400 are at least partially axially limited in the chamber 200. Therefore, unlocking the locking assembly can make the outer twisting head mold 300 and the inner twisting head mold 200 move relative to the driving member 400 and the base 100 along the axial direction of the driving member 400. In this way, the flat wire motor twisting device is easy to disassemble and assemble, thereby accelerating the change of shape.

[0036] Specifically, the locking assembly includes a cover plate 510 enclosing the chamber 110 with the base 100 and a locking member 520 capable of limiting the axial movement of the cover plate 510 along the driving member.

In this way, the first flange 410 and the second flange 420 can be rotated relative to the base 100, and the inner wall of the chamber 110 can limit the radial movement of the first flange 410 and the second flange 420; the first flange 410 can limit the radial movement of the first flange 210, and the second flange 420 can limit the radial movement of the second flange 310; when the first flange 410 and the second flange 420 are driven to rotate synchronously, the inner twist head mold 200 and the outer twist head mold 300 can be driven to rotate synchronously.

[0047] The second step is to install the second flange 420 . Specifically, the second flange 420 is installed in the chamber 110 of the base 100 , and the second flange 420 is overlapped on the first flange 410 .

[0048] The third step is to install the inner twisting head mold 200. Specifically, the first cylindrical boss of the inner twisting head mold 200 is placed on the first circular step 411 of the first flange 410, and the first protrusion 211 is matched with the first groove 412.

[0049] The fourth step is to install the outer twisting head mold 300. Specifically, the outer twisting head mold 300 is sleeved on the inner twisting head mold 200, and the second cylindrical boss of the outer twisting head mold 300 is placed on the second circular step 421 of the second flange 420, and the second protrusion 311 is matched with the second groove 422, and the second protrusion 311 is in contact with the radial end surface of the first flange 210 close to the second flange 310.

[0051] Step 6: Install the pressing block 521 . Specifically, place the pressing block 521 on the cover plate 510 .

[0052] Step 7: Lock the pressing block 521 on the base 100 by means of bolts 522 .

[0053] The process of replacing the twisting die of the flat wire motor twisting device with a new model is as follows:

[0054] In the first step, the bolt 522 is loosened to unlock the pressing block 521 from the base 100 .

[0055] The second step is to remove the pressing block 521.

[0056] The third step is to remove the cover plate 510 .

[0057] The fourth step is to take out the outer twist head mold 300.

[0058] The fifth step is to take out the inner twisting head mold 200.

[0059] In the sixth step, the first cylindrical boss of the new inner twisting head mold 200 is placed on the first circular step 411 of the first flange 410 , and the first protrusion 211 is matched with the first groove 412 .

[0064] When the wire motor twisting device is used, two layers of flat wire can be twisted at the same time. When the number of layers of the flat wire motor is greater than two, it is only necessary to design other twisting dies based on the first flange 410 and the second flange 420. After the twisting of the first and second layers of the flat wire motor is completed, the twisting die is replaced, and the third and fourth layers of the flat wire motor are twisted. In this way, it is not limited by the number of layers of the flat wire motor, and the cost of changing the model is low, the operation is simple, and the compatibility is strong. Since the twisting die has two layers of twisting at the same time, compared with the existing multi-layer twisting on the market, the structure is simpler, so the processing and manufacturing cost of the twisting die is lower.
