Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, in particular to an adjustable special-shaped cable conductor pressing device. Background Art

[0002] Special-shaped cables refer to cables with special shapes or structures. The types of special-shaped cables include special-shaped wire stranded conductor cables: including fan-shaped, tile-shaped, semicircular and other special-shaped conductor cables, which are mainly used for low-voltage power cables, which can effectively reduce the outer diameter of the cable and reduce material consumption; special-shaped single-filament stranded conductor cables: with the characteristics of compactness, high filling factor, and smooth surface, they are widely used in medium-voltage cables, which can reduce costs and improve cable performance; special round-flat cables with special structures: suitable for special occasions with small space and complex structures, such as electronic equipment. During the production process of special-shaped cables, the conductors in the cables need to be squeezed into a suitable shape, but it still has the following disadvantages in actual use:

[0003] 1. When extruding conductors of special-shaped cables, conductors of different shapes are directly extruded through a clamping device. However, when processing special-shaped cable conductors of different shapes, the extrusion structure needs to be replaced and the shape of the extruded cable needs to be adjusted. Replacing the extrusion structure requires disassembling multiple bolts and other structures, which makes it inconvenient to adjust the extrusion of special-shaped cable conductors of different shapes.

[0004] 2. In the process of conductor extrusion molding of special-shaped cables, the conductor has structures such as wires. When the wires are in a relatively loose state, extrusion molding can easily cause the wire structure to fail to enter the molding position, causing the shape of the molded conductor to not meet the requirements and affect its use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0027] See also Figure 1 , 4 The utility model is an adjustable special-shaped cable conductor compression device, comprising a fixed box 1, a movable block 2, a compression disc 3 and a pressure plate 4. The top of the fixed box 1 is symmetrically provided with a movable block 2. When the fixed box 1 is working, the driven gear 203 and the driving gear 5 are arranged therein. The outer side of the movable block 2 is movably connected with a compression disc 3, which is movably connected to the compression disc 3 through the movable block 2. When the compression disc 3 rotates, the conductor passing through the two compression discs 3 is pressed out of a corresponding shape. A limiting ring 302 is fixed at one end edge of the two compression discs 3. The limiting ring 302 of one compression disc 3 is arranged at the top, and the limiting ring 302 on the other compression disc 3 is arranged at the bottom. Through the cooperation of the limiting rings on the two limiting discs, when the cable conductor passes between the two compression discs 3, the cable conductor is restricted in position between the two compression discs 3. The tops of the two movable blocks 2 are both provided with a pressure plate 4. The pressure plate 4 outside the movable block 2 is arranged at the top of the compression disc 3, and the position between the movable block 2 and the compression disc 3 is determined by the pressure plate 4.

[0028] Specifically, the top of the fixed box 1 is symmetrically provided with movable holes 101 with a center line parallel to the short side as the symmetry axis, and pillars 102 are fixed at the four corners of the bottom of the fixed box 1. When the fixed box 1 is working, the rotating shaft 202 is movably connected through the movable holes 101, and the fixed box 1 is supported on the working plane by the pillars 102.

[0029] Furthermore, a rotating seat 201 is fixed to the bottom of each movable block 2, and a rotating shaft 202 is fixed to the bottom of each rotating seat 201. The rotating shaft 202 passes through the movable hole 101, and the bottom ends of the two rotating shafts 202 are fixed with driven gears 203. The bottom ends of the two driven gears 203 are rotatably connected to the bottom of the fixed box 1, and the two driven gears 203 are meshed with each other. When the movable block 2 is working, the position of the clamping plate 3 is supported and limited by the rotating seat 201. When the driven gear 203 rotates, the rotating shaft 202 is driven to rotate, and the rotating seat 201 is driven to rotate through the rotation of the rotating shaft 202. When the rotating seat 201 rotates and drives the movable block 2 to rotate, the clamping plate 3 rotates.

[0030] Furthermore, the circumferential sides of the two compression plates 3 are provided with compression grooves 303, and a movable opening 301 is provided along the central axis in the compression plate 3. The movable block 2 is movably connected in the movable opening 301.

[0031] The operation process of this embodiment is as follows: during operation, after the two clamping plates 3 above the fixed box 1 are installed, during the rotation of the two clamping plates 3, the cable conductor to be formed is guided between the two clamping plates 3, and enters the pressing groove 303 on the two clamping plates 3. The clamping plates 3 are pressed onto the cable conductor during the rotation, and are squeezed into a corresponding shape under the restriction of the two limit rings 302, so that during the extrusion molding of the cable conductor, it can effectively prevent the wire at the upper edge of the cable conductor from not fully entering the pressing groove 303 on the clamping plate 3 during the extrusion. Specific embodiment 2

When the movable block 2 is working, the clamping bolt 401 is threadedly connected through the mounting screw hole 204, and the pressure plate 4 is placed on the top of the movable block 2 on the pressure plate 3, and the clamping bolt 401 is inserted into the pressure plate 4 and then screwed into the mounting screw hole 204 on the movable block 2 until it is tightened, thereby restricting the movable block 2 and the pressure plate 3 together.

[0034] Specifically, a driving motor 501 is fixed to the bottom of the fixed box 1, and the output shaft of the driving motor 501 passes through the bottom of the fixed box 1, and a driving gear 5 is fixed to the end of the output shaft of the driving motor 501. The driving gear 5 is located inside the fixed box 1 and meshes with a driven gear 203 adjacent to it. The driving motor 501 drives the driving gear 5 to rotate. When the driving gear 5 rotates, it drives the two driven gears 203 to mesh with each other and rotate, thereby driving the pressure plate 3 to rotate.

[0035] The operation process of this embodiment is as follows: when working, first determine the corresponding shape of the formed conductor, then align the side edges of the two clamping plates 3 with each other, and ensure that the two limit rings 302 are placed above and below the pressure grooves 303 on the sides of the clamping plates 3. After completion, align the movable opening 301 on the clamping plate 3 with the two movable blocks 2, insert the movable block 2 into the movable opening 301 on the clamping plate 3, and after the clamping plate 3 is put on the movable block 2, insert the clamping bolt 401 into the pressure plate 4, and limit the position of the clamping bolt 401 by the rotating seat 201. After the pressure plate 4 is placed on the top of the movable block 2 and the clamping plate 3, rotate the clamping bolt 401 to screw the clamping bolt 401 into the movable block 2. After the mounting screw hole 204 on it is inserted into the mounting screw hole 204, the movable block 2 and the clamping plate 3 are restricted. When the clamping plate 3 needs to be removed, the clamping bolt 401 can be unscrewed to push the clamping plate 3 upward to be removed, and the new clamping plate 3 can be reinstalled. The extrusion shape of the conductor can be adjusted. After the clamping plate 3 is installed, the cable conductor to be processed can be guided between the two clamping plates 3. After completion, start the drive motor 501, and the drive motor 501 drives the drive gear 5 to rotate. Through the rotation of the drive gear 5, the two mutually meshing driven gears 203 are driven to rotate. At this time, the two clamping plates 3 rotate and will be guided into the pressing groove 303 between the two clamping plates 3 for extrusion molding.
