Description

Technical Field

[0001] This application belongs to the field of wire guide die manufacturing technology, specifically a single-twisted aluminum foil wire guide die. Background Technology

[0002] When producing Category 7 wires, the wire passing die must pass aluminum foil and core wire simultaneously. At the wire passing die position, the wire passes on the wire passing rod, and the position of the core wire cannot be fixed, which affects the longitudinal wrapping quality of aluminum foil and also has a certain impact on the appearance and electrical performance of the core wire insulation. Over time, the wire passing rod will wear out and produce gaps, which will scratch the wire. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a single-twisted aluminum foil wire passing mold that uses a magnetic hole on each side of the aluminum foil wire passing hole on the mold body to allow the core wire to pass through. This design prevents the core wire from being worn or scratched, thus solving the problem that existing wire passing molds are prone to causing wear and scratches on the core wire.

[0004] To achieve the above objectives, this application provides the following technical solution:

The connecting line segment A between the midpoints of the concave arcs on the two ceramic wheels located in the same magnetic hole is parallel to the connecting line segment B on the end face of the same side of the two ceramic wheels.

[0007] Preferably, the mold body has two rotating rollers at each end of each magnetic hole, the rotating rollers being perpendicular to the axis of the ceramic wheel, and the distance between the two rotating rollers located at the same end of the same magnetic hole being equal to the diameter of the virtual circle containing the concave arc.

[0008] Preferably, the projection of the concave arc on the opposite side of the two ceramic wheels located in the same magnetic hole onto the plane where the axes of the two ceramic wheels are located is a circle.

[0009] Preferably, the mold body also includes a cover plate, which has an installation channel. The rotating roller is installed in the installation channel. The cover plate is installed on both opposite side walls of the mold body. The two side walls on the mold body where the cover plate is installed are located at the two ends of the magnetic hole, respectively. The cover plate is fixedly connected to the mold body by bolts.

[0010] Preferably, the length of the magnetic hole is greater than the diameter of the ceramic wheel, the ceramic wheel is installed between the two ends of the magnetic hole, and the diameter of the rotating roller is greater than the axial length of the mounting channel.

[0019] Referring to 1-4, a single-twisted aluminum foil thread guide mold includes a mold body 1, wherein an aluminum foil thread guide hole 2 is provided in the center of the mold body 1, and a magnetic hole 3 is provided on each of the two sides opposite to the aluminum foil thread guide hole 2 on the mold body 1.

[0020] In this embodiment, by setting the magnetic hole 3, the core wire is passed through the magnetic hole 3, while the aluminum foil through hole 2 still passes through the aluminum foil. The magnetic hole 2 is not only wear-resistant but also has very little friction with the core wire, thereby improving the longitudinal wrapping quality of the aluminum foil, preventing scratches and damage to the core wire, and improving production efficiency and product quality. This solves the problem that existing wire separating dies easily lead to wear and scratches on the core wire.

[0021] As a preferred embodiment, each magnetic hole 3 is provided with two ceramic wheels 4, and the circumferential surface of each ceramic wheel 4 is a concave arc shape 5. The axes of the two ceramic wheels 4 located in the same magnetic hole 3 are located in the same plane and are parallel to each other. The connecting line segment A6 between the midpoints of the concave arc shapes 5 on the two ceramic wheels 4 located in the same magnetic hole 3 is parallel to the connecting line segment B7 on the end faces of the two ceramic wheels 4 on the same side. Providing ceramic wheels 4 within the magnetic hole 3 further prevents the surface of the core wire from contacting the magnetic hole 3. Simultaneously, the ceramic wheels 4 rotate during the movement of the core wire, thereby preventing scratches and damage to the core wire. The design of the concave arc shape 5 ensures that the circumferential surface of the ceramic wheel 4 does not scratch the core wire when it contacts it, while also limiting the movement of the core wire and preventing it from deviating under external force.

[0022] As a preferred embodiment, the mold body 1 is provided with two rotating rollers 8 at each end of each of the magnetic holes 3. By setting the rotating rollers 8, the problem of the core wire lacking a limiting device in the direction towards the two ends of the rotating rollers 8 is compensated. The rotating rollers 8 are perpendicular to the axis of the ceramic wheel 4, and the distance between the two rotating rollers 8 located at the same end of the same magnetic hole 3 is equal to the diameter of the virtual circle containing the arc of the concave arc 5.

[0023] As a preferred method, such as Figure 4 As shown, the projection of the concave arc on one side of the two ceramic wheels 4 located in the same magnetic hole 3 onto the plane where the axes of the two ceramic wheels 4 are located is a circle, and this circle is the core wire.

[0024] As a preferred embodiment, a cover plate 9 is also included. The cover plate 9 has an installation channel 10, within which the rotating roller 8 is disposed. The cover plate 9 is also disposed on opposite side walls of the mold body 1. The two side walls of the mold body 1 with the cover plate 9 are located at the two ends of the magnetic hole 3. The cover plate 9 is fixedly connected to the mold body 1 by bolts. This arrangement facilitates the installation of the rotating roller 8 and also facilitates its mounting onto the mold body 1 to cooperate with the ceramic wheel 4.

[0025] As a preferred embodiment, the length of the magnetic hole 3 is greater than the diameter of the ceramic wheel 4 (i.e., the axial length of the magnetic hole 3). Figure 1The distance from the front to the back of the mold body 1 shown is as follows: the ceramic wheel 4 is installed between the two ends of the magnetic hole 3, and the diameter of the rotating roller 8 is greater than the axial length of the mounting channel 10. After this arrangement, after the cover plate 9 is installed on the mold body 1, a part of the end of the rotating roller 8 can rest against the side wall of the magnetic hole 3. This facilitates positioning and installation, and also plays a role in assembly and fixation to a certain extent, preventing the whole formed by the cover plate 9 and the rotating roller 8 from radially moving on the mold body 1 relative to the magnetic hole 3.

[0026] In a preferred embodiment, the aluminum foil thread hole 2 and the magnetic hole 3 are separated by a baffle 11. A first mounting hole 12 is provided through the mold body 1, the axis of which is perpendicular to the axis of the magnetic hole 3 and parallel to the connecting line segment C between the two ceramic wheels 4. A second mounting hole 13 is provided through the baffle 11. A crossbar 14 extends from the mold body 1 through the first mounting hole 12 into the second mounting hole 13 to fix the baffle 11. This arrangement facilitates the installation of the ceramic wheels 4. During installation, the ceramic wheels 4 are first installed on the side wall of the magnetic hole 3, and then the baffle 11 is installed on the mold body 1, thus forming the magnetic hole 3 and the aluminum foil thread hole 2 on the mold body 1. Afterward, the crossbar 14 passes through the second mounting hole 13 and the first mounting hole 12 from the outside of the mold body 1, fixing the baffle 11 to the mold body 1 together.
