Description

Technical Field

[0001] The utility model relates to the technical field of overhead cables, in particular to a positioning device used for the production of overhead cables. Background Art

[0002] A cable is a conductor that transmits electricity from one location to another, consisting of one or more insulated conductors covered in an insulating layer. To protect people and animals from injury, it is covered with an insulating layer. The insulating performance of the insulating layer is determined by its thinnest point.

[0003] Existing cable insulation layers are typically produced using an extruder. The conductor is fed into the extruder, where the cable is wrapped so that the conductor and insulation layer are arranged in concentric circles. This ensures consistent insulation thickness everywhere. However, the production process requires constant debugging and correction of the mold core position, making the operation overly cumbersome and troublesome. Summary of the Invention

[0004] The purpose of the utility model is to provide a positioning device for overhead cable production to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] A positioning device for overhead cable production includes a centering mechanism, which includes a mold sleeve and a mold core. The mold core is provided with a plurality of first limiting grooves, which are arranged in a ring shape. The mold sleeve is provided with a plurality of second limiting grooves corresponding to the first limiting grooves. It also includes a sliding rod that is simultaneously slidably connected to the first limiting grooves and the second limiting grooves, and a centering column is fixed on the sliding rod. The mold sleeve and the mold core are both provided with openings in the center.

[0007] Furthermore, the first limiting groove is arranged to be inclined so as to enable the sliding rod to move toward or away from the center of the mold core.

[0008] Furthermore, the sliding rod is engaged with the second limiting groove.

[0009] Furthermore, an annular plate is fixedly connected to the mold sleeve, an inner side wall of the annular plate is provided with an internal thread, and an outer side surface of the mold core is provided with an external thread corresponding to the internal thread.

[0010] Furthermore, an annular handle is fixedly provided on the mold core.

[0011] Furthermore, a protective pad is provided on the outer surface of the centering column.

[0012] Furthermore, the number of the first limiting grooves is no less than 3.

[0013] Furthermore, the annular plate is provided with scale lines, and the annular handle is provided with an indicator plate.

[0014] In the above technical solution, the positioning device for overhead cable production provided by the present invention has the following beneficial effects:

[0015] Through the provided centering mechanism, the mold sleeve is fixedly installed at the inlet of the extruder, so that the conductor passes through the centering cavity and opening formed by the centering columns and enters the interior of the extruder. By rotating the mold core, the first limiting groove on the mold core drives the slide rod to move, and the movement of the slide rod is simultaneously restricted by the second limiting groove, so that the slide rod moves along the second limiting groove. The movement of the slide rod drives the corresponding centering column to move, so that different conductors can be centered to ensure the consistency of the thickness of the insulation layer.

[0016] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0025] See also Figure 1-3 A positioning device for overhead cable production includes a centering mechanism, which includes a mold sleeve 1 and a mold core 2. The mold core 2 is provided with a plurality of first limiting grooves 21, and the first limiting grooves 21 are arranged in a ring shape. The mold sleeve 1 is provided with a plurality of second limiting grooves 12 corresponding to the first limiting grooves 21, and also includes a sliding rod 3 that is simultaneously slidably connected to the first limiting grooves 21 and the second limiting grooves 12. A centering column 31 is fixed on the sliding rod 3, and openings are provided in the centers of the mold sleeve 1 and the mold core 2.

[0026] Through the provided centering mechanism, the mold sleeve 1 is fixedly installed at the inlet of the extruder, so that the conductor passes through the centering cavity and opening formed by the centering columns 31 and enters the interior of the extruder. By rotating the mold core 2, the first limiting groove 21 on the mold core 2 drives the slide rod 3 to move, and the movement of the slide rod 3 is also restricted by the second limiting groove 12, so that the slide rod 3 moves along the second limiting groove 12. The movement of the slide rod 3 drives the corresponding centering column 31 to move, so that different conductors can be centered to ensure the consistency of the thickness of the insulation layer.

[0027] Furthermore, the first limiting groove 21 is arranged to be inclined so as to enable the sliding rod 3 to move toward or away from the center of the mold core 2 .

[0028] Furthermore, the slide bar 3 is engaged with the second limiting groove 12 to ensure that the slide bar 3 does not tilt during the sliding process, so as not to affect the centering effect; the slide bar 3 can also be engaged with the first limiting groove 21, with the same effect.

[0029] Furthermore, the mold sleeve 1 is fixedly connected to an annular plate 13. The inner wall of the annular plate 13 is provided with internal threads, and the outer surface of the mold core 2 is provided with external threads corresponding to the internal threads. An annular handle 22 is fixedly attached to the mold core 2. Turning the annular handle 22 rotates the mold core 2 to center the conductor, and the mold core 2 can be locked in place after centering.

[0030] Furthermore, a protective pad is provided on the outer surface of the centering column 31 to reduce wear on the conductor surface.

[0031] Furthermore, the number of the first limiting grooves 21 is no less than 3 to ensure the centering effect.

[0032] Furthermore, a scale line is provided on the annular plate 13, and an indicator plate 4 is provided on the annular handle 22. The two ends of the scale line correspond to the two ends of the slide bar 3 at the first limiting groove 21, so as to facilitate adjustment by the staff.

[0033] Working principle: Through the set centering mechanism, the mold sleeve 1 is fixedly installed at the inlet of the extruder, so that the conductor passes through the centering cavity and opening formed by the centering columns 31 and enters the interior of the extruder. By rotating the annular handle 22, the mold core 2 can be driven to rotate, and the first limiting groove 21 on the mold core 2 drives the slide rod 3 to move. The movement of the slide rod 3 is also restricted by the second limiting groove 12, so that the slide rod 3 moves along the second limiting groove 12. The movement of the slide rod 3 drives the corresponding centering column 31 to move, so that different conductors can be centered to ensure the consistency of the thickness of the insulation layer.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
