[0008] The end surface of the main component is fitted with the end surface of the auxiliary component, and the main component and the auxiliary component are coaxially arranged, the sizing channel is opposite to the preforming channel, and the first wire passing hole is opposite to the second wire passing hole.

[0009] In one embodiment of the utility model, two threaded holes are symmetrically provided on both sides of the sizing channel, and two connecting holes are symmetrically provided on both sides of the preforming channel, and the positions of the threaded holes correspond to those of the connecting holes.

[0010] In an embodiment of the present invention, the threaded hole and the connecting hole are detachably connected via bolts.

[0011] In one embodiment of the present invention, a taper is provided inside the sizing channel, and the angle of the taper is 14°.

[0012] In one embodiment of the present invention, the diameter of the port of the sizing channel at one end close to the auxiliary component is larger than the diameter of the port at the other end of the sizing channel.

[0013] In one embodiment of the present invention, an external thread is provided on the outer side of the main body.

[0014] In one embodiment of the present invention, the cross section of the limiting channel is in the shape of an elongated strip.

[0015] In one embodiment of the present invention, the extension direction of the width of the limiting channel is tangent to the edge of the preformed channel.

[0016] A winding machine comprises the novel anti-single-sided coated aluminum strip overturning combined sizing die.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Embodiment 1

[0027] Reference Figure 1 As shown, the utility model discloses a novel anti-single-sided coated aluminum strip flip combined sizing die, comprising:

[0028] A main body 1, wherein a sizing channel 11 is axially opened at the center of the main body 1, and a first wire passing hole 12 is axially opened at one side of the sizing channel 11;

[0029] An auxiliary component 2, wherein a preformed channel 21 is provided in the center of the auxiliary component 2 along the axial direction, a second wire-passing hole 22 is provided on one side of the preformed channel 21, a limiting channel 23 is provided on the side of the preformed channel 21 away from the second wire-passing hole 22, and the limiting channel 23 is communicated with the preformed channel 21;

[0030] The end surface of the main component 1 is fitted with the end surface of the auxiliary component 2 , and the main component 1 and the auxiliary component 2 are coaxially arranged, the sizing channel 11 faces the preformed channel 21 , and the first wire hole 12 faces the second wire hole 22 .

[0031] It can be seen that the mold in the utility model includes two parts: a main part 1 and an auxiliary part 2. After the auxiliary part 2 is connected to the main part 1, the sizing channel 11 at the center of the main part 1 is connected to the preformed channel 21 at the center of the auxiliary part 2. During use, the cable core passes through the preformed channel 21 and the sizing channel 11 in sequence. The mold in the utility model needs to wrap the outer side of the cable core with aluminum foil, and the aluminum foil is wrapped on the outer side of the cable core in a longitudinal wrapping manner. In the actual operation process, the coated aluminum strip 3 passes through the preformed channel 21, and the single-sided coated aluminum strip 3 passes through the limiting channel 23 to fix the position of the single-sided coated aluminum strip 3; the limiting channel 23 is connected to the preformed channel 21 to form a 6-shaped channel, and the connection point between the two is the joint of the single-sided coated aluminum strip 3. After the entire mold is connected, the first wire hole 12 and the second wire hole 22 are connected for passing the drainage line. Specifically, the entire wire hole is arranged on the side of the preformed channel 21 away from the limiting channel 23, the closing part of the single-sided film-coated aluminum strip 3 is separated from the drain wire threading hole, and the position of the single-sided film-coated aluminum strip 3 is fixed by the limiting channel 23 and the preformed channel 21. The single-sided film-coated aluminum strip 3 will not rotate with the operation of the equipment, and the closing direction of the single-sided film-coated aluminum strip 3 is also fixed. During use, the single-sided film-coated aluminum strip 3 will not rotate with the operation of the equipment, and the closing direction of the single-sided film-coated aluminum strip 3 is also fixed, ultimately achieving the purpose of preventing the single-sided film-coated aluminum strip 3 from turning over and the drainage wire from entering the single-sided film-coated aluminum strip 3.

[0032] The utility model fixes the position of the single-sided coated aluminum strip 3 through the auxiliary part 2, so that the single-sided coated aluminum strip 3 will not rotate with the operation of the equipment, and also fixes the closing direction of the single-sided coated aluminum strip 3, so as to achieve the purpose of preventing the single-sided coated aluminum strip 3 from turning over and the dislocation problem of the discharge line entering the single-sided coated aluminum strip 3; secondly, the main body part 1 plays the role of shaping the single-sided coated aluminum strip 3, fixing the outer diameter of the semi-finished product and ensuring the overlap rate of the single-sided coated aluminum strip 3.

[0033] Furthermore, two threaded holes 13 are symmetrically provided on both sides of the sizing channel 11, and two connecting holes 24 are symmetrically provided on both sides of the preformed channel 21. The positions of the threaded holes 13 and the connecting holes 24 correspond to each other, and the threaded holes 13 and the connecting holes 24 are detachably connected by bolts.

[0034] Specifically, the auxiliary part 2 and the fixing part are fixedly connected by bolts. During the assembly process, the auxiliary part 2 is pressed against the fixing part, the two connecting holes 24 are aligned with the two threaded holes 13, and then the bolts are passed through the connecting holes 24 and connected with the threaded holes 13.

[0035] Furthermore, for double-shielded cables, the cable core needs to undergo a braiding process after passing through the above-mentioned mold, and a certain cable core diameter needs to be guaranteed; currently, this is achieved by reducing the lower die opening angle of the sizing die for the single-sided coated aluminum strip 3, which can easily cause wrinkles on the surface of the coated aluminum strip 3 during actual operation, affecting the overlap rate. In the utility model, a taper is provided inside the sizing channel 11, and the angle of the taper is 14°. The port diameter of the sizing channel 11 close to one end of the auxiliary part 2 is larger than the port diameter of the other end of the sizing channel 11. By providing a tapered sizing channel 11, the longitudinally wrapped aluminum strip 3 can be gradually sized to avoid wrinkles in the aluminum strip 3 and ensure the overlap rate of the entire aluminum strip 3 coating.

[0036] Furthermore, the outer side of the main body 1 is provided with an external thread 14. Specifically, during the assembly process, the auxiliary part 2 is first connected to the main body 1, and then the end of the main body 1 provided with the external thread 14 is connected to the device.

[0037] Furthermore, the cross section of the limiting channel 23 is in the shape of an elongated strip; the width extension direction of the limiting channel 23 is tangent to the edge of the preformed channel 21 .

[0038] Specifically, the entire limiting channel 23 and the preformed channel 21 are both arranged throughout the auxiliary component 2, and the limiting channel 23 is tangent to the preformed channel 21. After the two are spliced, their cross-section is in the shape of a 6; in the utility model, the height of the limiting channel 23 is greater than the thickness of the aluminum strip 3.
