Description

Technical Field

[0001] The invention belongs to the technical field of wire processing, and in particular relates to a wire extrusion processing device. Background Art

[0002] Power cables are used to transmit and distribute electric energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are used to transmit and distribute electric energy in the trunk lines of power systems. With the development of society, the amount of electricity consumed has also increased, requiring the current carrying capacity of cables to be larger and larger, and the cross-section of the conductive core of high-voltage power cables to be continuously increased. At present, most cables on the market are made of twisted metal wires. In order to protect the metal wires, it is often necessary to cover the metal wires with a layer of plastic protective sheath. In the production process, an extrusion mold is generally used to extrude a layer of plastic protective sheath on the metal wires using plastic materials PVC or PE.

[0003] A Chinese patent with authorization announcement number CN117116566B discloses an automatic extrusion device for producing ultra-flexible aluminum conductor cables, including an extrusion head mold through which the cable can pass and through which molten masterbatch is coated on the cable. The extrusion head mold includes a molding seat, a rounding rotating component and a rounding driving component. The present invention arranges the rounding rotating component rotatably at the outlet end of the extrusion channel, and arranges the rounding driving component at the inlet end of the extrusion channel, and the rounding driving component and the rounding rotating component are transmission-connected, so that when the cable slides through the rounding driving component, the extrusion channel and the rounding rotating component, the rounding driving component can automatically drive the rounding rotating component to round the coating on the cable, so that the rounding rotating component can adapt to the sliding speed of the cable, so that the cross-section of the formed cable has a regular circular structure, which is convenient for the subsequent use of the cable.

[0004] Although the above technical solution can drive the rolling rotation component through the rolling drive component to achieve the rolling operation of the cable, it should be noted that the rotation axis of the driven wheel in the rolling drive component is arranged parallel to the axis of the cable. This arrangement may cause a relatively large friction between the driven wheel and the cable. In mild cases, this may only cause scratches on the surface of the wire core; in severe cases, it may significantly increase the radial tension on the cable, resulting in elongation, deformation, or even breakage of the cable.

[0009] A further technical solution of the present invention is that a wedge block is arranged inside the mounting shell, one end of the wedge block close to the rolling assembly is higher than the other end, and the end of the support column away from the wire core slides on the inclined surface of the wedge block, so that the distance between the two support columns can be adjusted.

[0010] A further technical solution of the present invention is that two extension blocks are provided on each of the said columns, and the said extension blocks are provided at one end close to the wire core, and the two said extension blocks slide on the said columns, and a second elastic member is provided between the two said extension blocks to make the two extension blocks slide outward.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 6 , the present invention provides the following technical solutions: a wire extrusion processing device, including a rounding component 1, a mounting shell 2, a transmission component 3 and a direct-reaching component 4;

[0028] Among them, the rolling component 1 is installed on the installation shell 2, and the rolling component 1 can roll the coating on the wire. The transmission component 3 is also arranged on the installation shell 2. The cable passes through the transmission component 3 to move the transmission component 3, and drives the rolling component 1 to move through the transmission component 3, so that the rolling component 1 rolls the coating on the wire. When the wire core drives the transmission component 3 to move, the transmission component 3 will squeeze the wire core. When encountering a multi-strand hinged wire core, the transmission component 3 will easily squeeze the multi-strand wire core out of position, so that the cross-section of the multi-strand wire core will be squeezed from the original circular distribution to a flat shape, so that the wire core under the coating is flat, which can easily lead to a reduction in the strength of the wire. Therefore, the direct-reaching component 4 is also installed on the installation shell 2, and the direct-reaching component 4 can be against both sides of the wire, so as to avoid the transmission component 3 squeezing the wire and causing deformation of the wire.

[0029] See also Figure 1-3The rounding component 1 includes a rotating shell 11, which is cylindrical and hollow in the middle. The rotating shell 11 rotates on the mounting shell 2. The mounting shell 2 is provided with an injection molding pipe, through which molten masterbatch can be injected into the extrusion channel. A bearing is provided between the rotating shell 11 and the mounting shell 2, which can be used to reduce the friction between the rotating shell 11 and the mounting shell 2. Of course, in order to prevent the rotating shell 11 from sliding on the mounting shell 2, the rotating shell 11 and the mounting shell 2 can be limited by a card slot card block (not shown in the figure). Four rounding wheels 12 distributed in a ring array are provided on the rotating shell 11. The wire passes through the four rounding wheels 12, so that the rounding wheels 12 are against the wire and rotate around the wire, so that the coating on the wire can be rounded.

[0030] Slide posts 13 are integrally provided at both ends of the rolling wheel 12, and adjusting plates 14 are provided at both ends of the rolling wheel 12. The adjusting plates 14 are in the shape of a disk and can rotate inside the rotating shell 11. Four inclined grooves are evenly provided on the adjusting plates 14. The four slide posts 13 all slide inside the inclined grooves. A side plate 15 is provided inside the rotating shell 11. The side plate 15 is integrally formed with the rotating shell 11. A vertical groove is provided on the side plate 15. The slide posts 13 penetrate the inclined grooves and extend to the inside of the vertical grooves. When the adjusting plate 14 rotates, the movement of the slide posts 13 can be limited by the vertical grooves first, so that the slide posts 13 can only move in the vertical direction. In addition, the inclined grooves move relative to the vertical grooves, so that the slide posts 13 can be pushed to slide inside the vertical grooves, and then the four rolling wheels 12 can be driven to move closer to or farther away from each other to adjust the size of the rolling diameter.

[0031] The two adjustment plates 14 are each provided with a mounting ear 16, which passes through the outside of the rotating shell 11 and is connected to the mounting ears 16 on the two adjustment plates 14 by a connecting rod, and a top screw that abuts against the rotating shell 11 is provided on the connecting rod. When in use, the top screw is first loosened, and then the adjusting plate 14 is rotated by toggling the connecting rod, thereby achieving the effect of adjusting the rolling wheel 12, and then the top screw is rotated to make the top screw abut against the rotating shell 11, so that the rotation angle of the rotating shell 11 can be fixed.

[0032] See also Figure 1 , Figure 2 and Figure 4The transmission assembly 3 includes two driven wheels 31, which are arranged perpendicularly to the wire core, so as to avoid the driven wheels 31 from scratching the wire core. The wire core is located between the two driven wheels 31, so that the wire core can be clamped between the two driven wheels 31 and abut against the wire core. Therefore, when the wire core moves, the friction between the wire core and the driven wheel 31 can make the driven wheel 31 rotate. One side of the driven wheel 31 penetrates the outside of the mounting shell 2 and is provided with a gear 32. The mounting shell 2 is provided with a gear ring 33, and the gear ring 33 is provided with an inner gear ring, so that the gear 32 is meshed with the inner gear ring. The gear ring 33 can also be limited by a slot block (not shown in the figure), so that the gear ring 33 can only It can rotate on the mounting shell 2, and an end face tooth 34 is also provided on one end face of the rotating shell 11, and an outer tooth ring is provided on the tooth ring 33, and the outer tooth ring can mesh with the end face tooth 34, so when the tooth ring 33 rotates, the rotating shell 11 can be driven to rotate by the end face tooth 34. When in use, the wire core moves, and the two driven wheels 31 can be driven to rotate by friction, so that the driven wheel 31 can drive the gear 32 to rotate, and the gear 32 meshes with the tooth ring 33, so that the tooth ring 33 rotates. When the tooth ring 33 rotates, it meshes with the end face tooth 34, so that the tooth ring 33 can drive the rotating shell 11 to rotate through the cross-sectional teeth, and then drive the rolling wheel 12 to round the wire.

[0033] Slide bars 35 are provided at both ends of the driven wheel 31, and a first slide groove 21 for sliding the slide bar 35 is provided on the mounting shell 2. The first slide groove 21 is arranged along the length direction of the mounting shell 2. Both ends of the slide bar 35 slide inside the two first slide grooves 21. A first elastic member 37 is arranged inside the first slide groove 21. The first elastic member 37 is a compression spring, which pushes the slide bar 35 to move to the side close to the rolling component 1. A second slide groove 36 is provided on the slide bar 35, and the driven wheel 31 can slide inside the second slide groove 36. An arc groove 22 is provided on the side wall of the mounting shell 2. Both ends of the driven wheel 31 can pass through the arc groove 22 to the outside of the mounting shell 2 and be connected to the gear 32. The arc groove 22 is concentrically arranged with the gear ring 33. When the driven wheel 31 drives the gear 32 to move along the arc groove 22, it can always mesh with the inner tooth ring on the gear ring 33. When in use, the first elastic member 37 can push the slide bar 35 to move in the direction close to the rolling component 1, so that the slide bar 35 drives the driven wheel 31 to move. Since the driven wheel 31 slides inside the arc groove 22 and the second slide groove 36 at the same time, the two driven wheels 31 can approach each other through the arc groove 22, so that they can be against the outer surface of the wire core, so that the movement of the wire core can drive the driven wheel 31 to rotate. Through the setting of the first elastic member 37, it can be suitable for wire cores of different thicknesses. At the same time, through the setting of the arc groove 22, the adjustment of the distance between the driven wheels 31 can make the gear 32 mesh with the inner tooth ring on the gear ring 33.

[0034] When multiple strands of wire cores are hinged, when the wire cores are squeezed by the two driven wheels 31, the multiple strands of wire cores are easily misaligned, causing the cross section of the wire core to become a flat distribution shape. When the wire core is extruded in this state, the strength of the wire is easily reduced. In addition, the thickness of the coating is different, which makes the coating layer more likely to break.

[0035] See also Figure 4-6 As shown, therefore, a direct contact component 4 is installed in the middle of the slide bar 35, and the direct contact component 4 includes a contact column 41 sliding in the middle of the slide bar 35, and the contact column 41 is located between the two driven wheels 31, and one end of the contact column 41 can contact one side of the wire core, so as to limit the deformation of the side of the wire core and prevent the wire core from being squeezed into a flat shape;

[0036] In order to adapt to wire cores of different thicknesses, a wedge block 23 is integrally formed inside the mounting shell 2, and one end of the wedge block 23 close to the rolling component 1 is higher than the other end, and the end of the support column 41 away from the wire core slides on the inclined surface of the wedge block 23. When the support column 41 slides on the inclined surface of the wedge block 23, the distance between the two support columns 41 can be adjusted. During use, when the wire core is relatively thick, the distance between the two driven wheels 31 increases. Under the action of the arc groove 22, the two driven wheels 31 move in the direction away from the rolling component 1, and at the same time drive the slide bar 35 and the support column 41 installed on the slide bar 35 to move in the direction away from the rolling component 1, so that the support column 41 slides on the inclined surface of the wedge block 23, and the distance between the two support columns 41 can be adjusted, so that the direct-reaching component 4 can adapt to wire cores of different thicknesses. In summary, the direct-reaching component 4 can be automatically adjusted according to wire cores of different thicknesses, so that the direct-reaching component 4 can adapt to wire cores of different thicknesses.

[0037] See also Figure 4 and Figure 6 An extension block 411 is provided at one end of the support column 41 close to the wire core. The extension block 411 can increase the area of ​​the wire core so as to adapt to thicker wire cores. Two extension blocks 411 are provided on each support column 41. The two extension blocks 411 slide on the support column 41, and a second elastic member 412 is provided between the two extension blocks 411. The second elastic member 412 is a compression spring, which can push the two extension blocks 411 outward and make the two extension blocks 411 abut against the two driven wheels 31. When in use, when the wire core is thicker, the distance between the two driven wheels 31 will become larger, so the second elastic member 412 will push the two extension blocks 411 outward to expose and increase the abutment area between the support column 41 and the wire core.
