Description

Technical Field

[0001] The utility model relates to the field of cable processing, in particular to a cable extruder shaping device. Background Art

[0002] The cable extruder is a hot extrusion equipment. The reeled cable or cable core is placed on the pay-off device and a certain tension is ensured. After passing through the tensioning and straightening device, it enters the extruder head to extrude the insulation layer or sheath layer. The plastic particles are added to the extruder barrel through the hopper. Due to the rotation of the screw, they enter the machine chamber. On the one hand, they are heated, and on the other hand, the screw rotates and stirs, which promotes the plasticization of the plastic and pushes it to the head and extruded from the die. It is completely, tightly and continuously extruded on the wire and cable core or cable core.

[0003] For example, a patent with authorization announcement number CN220984245U discloses an extruder that facilitates uniform extrusion of cables, including a base, a support frame is fixedly connected to the top of the base, an extrusion equipment body is fixedly connected to the top of the support frame, a first discharge port is fixedly connected to one end of the extrusion equipment body, a mounting frame is fixedly connected to one side of the top of the base, a fixed frame is fixedly connected to one side of the mounting frame, a pull rod is movably connected to the interior of the fixed frame, and a spring is movably sleeved on the surface of the pull rod.

[0004] The above patent can extrude the cable through the extrusion equipment body, and the cable can be wrapped in extruded material for discharge through the first discharge port. The spring can be extended and retracted to push the connecting block to move, and the connecting block can drive the limit block to move. The limit block can be used to limit the cable to prevent the cable from being unstable when the extruded material on the surface is scraped flat. However, the disadvantage of the above patent is that when the above patent shapes the cable, a molding block is used to remove the surface material, which results in excessive material adhering to the surface of the wire during extrusion and then removing it, causing waste.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0025] The mounting plate 1 is integrally in the shape of a rectangular plate and there are two groups. There are at least eight mounting brackets 2 arranged between the two groups of mounting plates 1. These eight mounting brackets 2 are integrally in the shape of a regular octagon. At the same time, waist-shaped holes 3 are formed in the mounting brackets 2; a cable passing hole 103 is also formed in the center of the mounting plate 1;

[0026] Specifically, eight rectangular slots 101 adapted to the ends of the mounting brackets 2 are formed on the inner side of the mounting plate 1. At the same time, through holes passing through the mounting plate 1 are also formed in the slots 101. The ends of the mounting brackets 2 are rectangular. The ends of the mounting brackets 2 are inserted into the slots 101. Threaded holes are also formed at the ends of the mounting brackets 2. Screws pass through the through holes in the mounting plate 1 and are threadedly connected to the threaded holes at the ends of the mounting brackets 2, thereby fixing the mounting brackets 2 to the mounting plate 1;

[0027] Meanwhile, in this solution, in order to install the mounting plate 1, ear plates 102 are extended outwardly at the bottoms of the front and rear sides of the mounting plate 1. Through holes are formed in the ear plates 102 for installing the mounting plate 1;

[0028] At least eight groups of shaping mechanisms 4 are provided, and these eight groups of shaping mechanisms 4 are respectively installed on eight mounting frames 2. These eight groups of shaping mechanisms 4 are distributed in a spiral shape and respectively support eight directions in the radial direction of the cable; thus, the side wall of the cable after extrusion can be subjected to the pressure of the shaping mechanism 4 in each direction.

[0029] The shaping mechanism 4 includes a shaping wheel 401. An arc-shaped shaping groove 402 is formed on the side surface of the shaping wheel 401. The radian of the arc-shaped shaping groove 402 is greater than 45° to ensure that the eight shaping mechanisms 4 can cover the entire side surface of the cable;

[0030] Furthermore, the radian of the arc-shaped shaping groove 402 is greater than 60° to ensure a better extrusion and shaping effect of the shaping groove 402 on the cable.

[0031] The shaping wheel 401 is rotatably sleeved on a wheel shaft 404 through a bearing 403. The wheel shaft 404 is fixedly installed on the side surface of a mounting arm 405. At the same time, at least two threaded rods 406 extend upward from the top of the mounting arm 405; the threaded rods 406 pass through the waist-shaped holes 3 on the mounting frame 2; at the same time, at least two adjusting nuts 407 are threadedly connected to the threaded rods 406, and the adjusting nuts 407 are respectively located on both sides of the mounting frame 2. The adjusting nuts 407 are used to adjust the height of the threaded rods 406, and thus adjust the position of the shaping wheel 401;

[0032] When the utility model is in use, the cable just extruded enters the shaping mechanism 4 through the cable through hole 103 of one mounting plate 1, and then is led out through the cable through hole 103 of the other mounting plate 1. When the cable passes through the shaping mechanism 4, the shaping groove 402 of the shaping wheel 401 extrudes the cable to shape the cable. The eight spiral-shaped shaping wheels 401 perform shaping processing on each direction of the side surface of the cable, so as to obtain a cable product with a smooth surface and a circular cross-section.
