Description

Technical Field

[0001] The invention relates to the technical field of cable production, and in particular to a cable production roundness finishing positioning device and method. Background Art

[0002] Cables are widely used in daily life and are one of the indispensable infrastructures. They are mainly used for multiple functions such as controlling installation, connecting equipment, and transmitting electricity. For example, power cables are used to transmit electric energy, and communication cables are used to transmit signals. At present, in the cable production process, a group of finished cables is usually formed by twisting multiple strands of thinner cables. During the twisting process, in order to ensure good heat dissipation and stability of the cables, the cables need to be specially processed for roundness. The better the roundness of the cable, the better the heat dissipation and the less wear during use.

[0003] At present, after the roundness precision production processing, the cable needs to be specially processed, positioned and cooled between the twisting and the roundness precision processing, so as to support the subsequent detection and roundness precision processing, and to level the position of the cable that is not round enough. The current processing positioning device mainly uses a pulley to support the cable position and limit and cool the cable position, and has a single function. During the twisting process, gaps are likely to exist during the twisting process of multiple groups of cables. Even in the subsequent coating process, the gaps between the sub-cables and the sub-cables cannot be effectively removed, so that after the subsequent coating is completed, there are gaps in multiple positions inside the finished cable. Such gaps will directly reduce the roundness of the cable, increase the workload of subsequent detection and roundness precision processing, and also reduce the quality of the cable. In view of the shortcomings of the prior art, the present invention provides a cable production roundness precision processing positioning device and method thereof to solve the above problems.

[0080] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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.

[0081] The embodiment of the present application provides a cable production roundness finishing positioning device and method thereof, which solves the problem that the current processing positioning device mainly uses pulleys to support and limit the cable position and cool the cable, has a single function, and is prone to gaps during the twisting process of multiple groups of cables. Even in the subsequent coating process, the gaps between the sub-cables cannot be effectively removed, so that after the subsequent coating is completed, gaps exist in multiple positions inside the finished cable. Such gaps will directly reduce the roundness of the cable, increase the workload of subsequent inspection and roundness finishing, and reduce the quality of the cable.

[0082] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0083] Embodiment 1:

[0084] The embodiment of the present invention discloses a cable production roundness finishing positioning device. Figure 1 To Attachment Fig.15 As shown, it includes a capstan positioning unit 1, a pre-processing positioning unit 2, a secondary processing unit 3, a full-circle positioning mechanism 4 and a full-circle cooling mechanism 5;

[0085] The winch positioning unit 1 comprises a first base 11 and a winch box 12 arranged on the first base 11, and a winch body 13 for twisting multiple cables is arranged on the winch box 12; the winch positioning unit 1 twists the multiple cables through the winch body 13;

[0086] The winch body 13 is made of steel and has sufficient strength and rigidity to withstand the pressure and torque when the cables are twisted. During the twisting process, the winch body 13 rotates at a certain speed to tightly twist the multiple cables together.

[0087] The winch box 12 is used to accommodate the winch body 13 and provide necessary support and protection; the first base 11 is used to fix the winch box 12 to ensure the stability and accuracy of the winch positioning unit 1;

[0088] The pretreatment positioning unit 2 is arranged at the tail end of the capstan positioning unit 1. The pretreatment positioning unit 2 includes a second base 21 and a first extrusion device 22 arranged on the second base 21. The first extrusion device 22 is improved to pre-treat and coat the filling material at the cable twisting position. The first extrusion device 22 has an internal positioning coating component 221 built in. The internal positioning coating component 221 includes an extrusion head 2211 arranged inside the first extrusion device 22 and an extrusion tube 2212 arranged on the extrusion head 2211. The extrusion tube 2212 is provided with a positioning sleeve 2213 for positioning the cable twisting position.

[0089] The pretreatment positioning unit 2 pre-treats the cable through the first extrusion device 22, and coats the first filling material. The first filling material can be a polyurethane material. The polyurethane can fill the gap after the cable is twisted, enhance the integrity and roundness of the cable, and facilitate the subsequent roundness finishing.

[0090] The first extrusion device 22 has a built-in positioning coating component 221, which evenly coats the filling material at the cable twisting position through an extrusion head 2211 and an extrusion tube 2212. The positioning sleeve 2213 is used to ensure that the filling material is accurately coated at the desired position.

[0091] The extrusion head 2211 is the core component of the first extrusion device 22, which is responsible for extruding the filling material and coating it on the cable through the extrusion tube 2212 and the positioning sleeve 2213. The extrusion tube 2212 is connected to the extrusion head 2211. The extrusion tube 2212 is used to transfer the filling material source to the positioning sleeve 2213 to ensure that the filling material can flow smoothly to the twisting position of the cable in the positioning sleeve 2213.

[0092] A return assembly 222 is provided between the extrusion tube 2212 and the positioning sleeve 2213, and the return assembly 222 includes:

[0093] The connecting pipe 2221 is arranged between the extrusion pipe 2212 and the positioning sleeve 2213;

[0094] The first driving member 2222 is disposed on the connecting pipe 2221;

[0095] The screw push rod 2223 is disposed at the output end of the first driving member 2222 , and the screw push rod 2223 is rotatably connected in the connecting pipe 2221 .

[0096] The device facilitates the recovery and reuse of excess filling materials through the design of the return assembly 222, thereby preventing the filling materials from accumulating inside the positioning sleeve 2213;

[0097] The working principle of the return assembly 222 is to utilize the first driving member 2222 to drive the spiral push rod 2223 to rotate. Since the connecting pipe 2221 connects the extrusion tube 2212 and the positioning sleeve 2213, the extrusion tube 2212 transports the excess material from the positioning sleeve 2213 to the extrusion tube 2212, so that the material can be reused.

[0098] The extrusion tube 2212 is connected to a ring tube 22121 , and the ring tube 22121 is connected to a plurality of groups of multi-angle tubes 22122 . The multi-angle tubes 22122 are connected to the positioning sleeve 2213 .

[0099] Through the design of the ring tube 22121 and the multi-angle tube 22122, the cable can be coated at different positions and angles during coating to ensure uniform coating, so that the first material pretreatment effect is good during the cable twisting process, the cable twisting gap filling effect is good, and the subsequent cable positioning process and transportation process are highly stable.

[0100] The secondary processing unit 3 is arranged at the rear end of the pre-processing positioning unit 2, and the secondary processing unit 3 includes a third base 31 and a second extrusion device 32 arranged on the third base 31;

[0101] The full-circle positioning mechanism 4 includes a first positioning mechanism 23 disposed on the second base 21 and a second positioning mechanism 33 disposed on the third base 31;

[0102] The full-circle cooling mechanism 5 includes a first cooling mechanism 24 disposed on the second base 21 and a second cooling mechanism 34 disposed on the third base 31 .

[0103] In the secondary processing unit 3, the secondary processing unit 3 performs secondary processing on the cable through the second extrusion equipment 32 and coats the second protective material. The second extrusion equipment 32 has the same basic equipment principle as the traditional technology, and coats the material on the surface of the pretreated cable. The protective material selected for coating the second material is polyethylene. Polyethylene has good wear resistance and corrosion resistance. On the one hand, it enhances the service life and performance of the cable. On the other hand, when the pretreated cable is coated with the material again, there is no gap inside and the roundness is good, which is convenient for subsequent roundness detection and fine-tuning of fine processing.

[0104] A second aspect of the present invention provides a method for producing a roundness finishing positioning device for a cable, the method comprising the following steps: step S1, twisting the cable through a capstan positioning unit 1;

[0105] Step S2, the twisted position is pre-treated by the pre-treatment positioning unit 2, so that the cable passes through the pre-treatment process of the first extrusion device 22 and the inner positioning coating component 221 before twisting, and the filling material is attached to the surface of the cable, and the gap between the cables is tightly filled after twisting;

[0106] Step S3, the twisted cable is initially positioned by the first positioning mechanism 23, and then cooled and formed by the first cooling mechanism 24 to maintain initial roundness;

[0107] Step S4, the secondary processing unit 3 attaches a second protective material to the twisted cables;

[0108] Step S5, the cable is positioned again by the second positioning mechanism 33, and is cooled and shaped for the second time by the second cooling mechanism 34, so as to keep the subsequent roundness of the cable uniform, and facilitate the subsequent roundness positioning detection and fine processing.

[0109] The cable production roundness finishing positioning device adopts a capstan positioning unit 1 to perform twisting and positioning of multiple groups of sub-cables, and a pre-treatment positioning unit 2 provides surface filling material coating pre-treatment for the multiple groups of sub-cables at the twisted positions, so that the gaps when the multiple groups of sub-cables are twisted are filled, and then after positioning, extrusion, cooling and shaping, they are sent to the secondary processing unit 3 to form an outer sheath layer, thereby ensuring that no gaps are generated between the multiple groups of sub-cables. The finished cable has high roundness. The design of the pre-treatment positioning unit 2 and the secondary processing unit 3 can achieve good support, cooling and positioning effects on the cables. At the same time, the roundness level of the cables is improved, the workload of subsequent detection and roundness finishing is reduced, and the use requirements are met.

When the second driving member 451 is working, it drives the first screw rod 4521 to rotate, the first screw rod 4521 drives the second bevel gear 4529 to rotate, the second bevel gear 4529 drives the first bevel gear 4528 to rotate, the first bevel gear 4528 drives the guide shaft 4526 to rotate, the guide shaft 4526 drives the third gear 4527 to rotate, the third gear 4527 drives the second gear 4525 to rotate, the second gear 4525 drives the first gear 4523 to rotate, and the first gear 4523 drives the second screw rod 4522 to rotate;

[0142] Among them, the first screw rod 4521 and the second screw rod 4522 rotate synchronously, the first screw rod 4521 drives the vertical lifting frame 432 to slide along the first track frame 431, the vertical lifting frame 432 drives the first positioning wheel 41 to move, the second screw rod 4522 drives the horizontal adjustment frame 442 to move along the second track frame 441, and the horizontal adjustment frame 442 drives the second positioning wheel 42 to move. Therefore, the position adjustment of the first positioning wheel 41 and the second positioning wheel 42 is convenient, and the position of the first positioning wheel 41 and the second positioning wheel 42 is convenient for clamping or releasing the cable in the vertical and horizontal directions.

[0143] The vertical lifting frame 432 and the horizontal adjustment frame 442 are respectively provided with a docking mechanism 6 for supporting the first positioning wheel 41 and the second positioning wheel 42, and the docking mechanism 6 includes:

[0144] A plurality of sets of card holders 61, which are respectively arranged on the vertical lifting frame 432 and the horizontal adjustment frame 442;

[0145] A plurality of groups of clamping blocks 62 are respectively arranged on the first positioning wheel 41 and the second positioning wheel 42, and a clamping slot 621 is formed on the clamping block 62;

[0146] The locking assembly 63 is disposed on the holder 61 and is used to limit the position of the block 62 .

[0147] The device is designed with a docking mechanism 6, so that the first positioning wheel 41 and the second positioning wheel 42 can be easily installed and positioned on the vertical lifting frame 432 and the horizontal adjustment frame 442. Therefore, the subsequent disassembly, maintenance or replacement of the first positioning wheel 41 and the second positioning wheel 42 is convenient. When the cable model is changed later, it is convenient to quickly replace the first positioning wheel 41 and the second positioning wheel 42 to adapt to various line types, thereby providing stable support and positioning for cable processing, thereby ensuring good positioning and support effect during roundness finishing.

[0148] When installing the first positioning wheel 41 and the second positioning wheel 42 , the clamping block 62 is directly aligned with the inside of the clamping seat 61 and clamped, and the clamping block 62 is locked by using the locking assembly 63 . The operation is convenient, time-saving and labor-saving.

[0149] The locking assembly 63 comprises:

[0150] The pressing rod 631 is rotatably connected to the card holder 61;

[0151] The lock head 632 is disposed on the pressure rod 631, and the lock head 632 is movably engaged in the card slot 621;

[0152] The spring 633 is disposed between the pressing rod 631 and the clamping seat 61;

[0153] The locking assembly 63 has a simple structure. When using the locking assembly 63 to lock the card block 62, first press the pressure rod 631 to make the pressure rod 631 rotate and drive the lock head 632 to tilt up. At the same time, the pressure rod 631 squeezes the spring 633. At this time, the card block 62 can be clamped in the clamping seat 61. When the pressure rod 631 is released after clamping, the spring 633 resets and pushes the pressure rod 631 to rotate, so that the pressure rod 631 drives the lock head 632 to be clamped in the clamping groove 621, thereby realizing the locking of the card block 62 and realizing the installation of the first positioning wheel 41 and the second positioning wheel 42.

[0154] The full-circle cooling mechanism 5 comprises:

[0155] A connecting frame 51, which is arranged on the base;

[0156] A cooling guide seat 52, which is disposed on the connecting frame 51;

[0157] A water inlet pipe 53 is provided on the cooling guide seat 52;

[0158] The water outlet pipe 54 is disposed on the connecting frame 51 .

[0159] The cable production roundness finishing positioning device has a simple round cooling mechanism 5. After the cable is supported by the first positioning wheel 41 and the second positioning wheel 42, it is limited inside the cooling guide seat 52. At this time, the water inlet pipe 53 is connected to the pump group and continuously transports water through the water tank. The water is transported to the cooling guide seat 52 by the water inlet pipe 53 to cool the cable inside the cooling guide seat 52. The cooling water eventually flows into the connecting frame 51 under the action of gravity, and is then discharged and collected through the water outlet pipe 54 to achieve cable limitation and cooling.
