[0002] For copper-clad steel strands, the essence is to twist steel wires on copper wires according to the principle of wire twisting machine / bundle twisting machine. For details, please refer to the related contents in CN116281410A and CN113104671A. The principle is relatively simple, taking steel core as the bus and multiple copper core wires as the sub-wires to continuously wind on the bus through the rotating disc structure.

[0003] The overall wire twisting quality is directly related to the bus traction speed and the sub-wire rotation speed, which is specifically manifested in the twisting gap and winding force between the sub-wire and the bus. The twisting process is continuous, and during the whole wire operation, local problems such as poor bonding, over-torque, and loose twisting may occur due to equipment or material problems. If these problems are not found and handled in time, they will directly affect the subsequent twisting quality. Therefore, it is necessary to find and remove the abnormal points in the completed copper-clad steel strands, which is troublesome and requires cutting out the abnormal point position, thus affecting the quality of the whole copper-clad steel strand. To this end, the present application provides a solution. SUMMARY

[0008] Further, a coordinated oil sleeve is installed at an outer end position of the passive oil cylinder, the inside of the coordinated oil sleeve is connected to the inside oil cavity of the passive oil cylinder, and the inside of the coordinated oil sleeve is provided with an electric connector group and a spring two, and the outside of the coordinated oil sleeve is provided with a buzzer corresponding to the electric connector group.

[0009] Further, one sleeve of the three wing plates is slidingly connected to one guide column and arranged as a middle position, and the other two sleeves of the three wing plates are slidingly connected to the guide columns at adjacent positions and arranged as bidirectional side positions, and the middle position is located between the two bidirectional side positions and provided with a spring one.

DETAILED DESCRIPTION

[0018] The technical solutions of the application will be described clearly and completely below in combination with the embodiments. Obviously, the described embodiments are only some of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0019] Embodiment one: for the stranding process of copper-clad steel wire, the busbar pulling speed and the sub-wire rotating speed directly affect the forming quality of the copper-clad steel wire, and the key lies in: because the whole wire is continuously carried out, if the abnormal production state cannot be found in time, it will also directly affect the whole wire production efficiency and production quality, such as temporary shutdown operation or abnormal point removal, etc. The following technical solutions are proposed: Reference Figures 1-9 In this embodiment, the multi-wire bundle stranding device based on copper-clad steel wire processing includes a tool base 1 and a rear base 4. The tool base 1 is provided with a tool frame 5. The tool frame 5 is provided with a wire wheel frame 6 corresponding to the sub-wire ZX at the position away from the rear base 4. The tool frame 5 is provided with a plurality of three-wing plates 7 corresponding to the wire wheel frame 6. The three-wing plate 7 is in a three-pronged arc shape, and a sleeve is arranged at the triangular position of the three-wing plate 7. The reversing guide wheel set 12 corresponding to the sub-wire ZX is installed at the middle position of the upper surface of the three-wing plate 7. The three-wing plates 7 are arranged in a ring array along the center point of the tool frame 5. Each three-wing plate 7 is arranged in a staggered distribution through the sleeve. The rear base 4 is provided with a wire pressing sleeve 17 corresponding to the busbar MX at the position close to the tool frame 5. The wire pressing sleeve 17 is provided with a wire pressing port corresponding to the sub-wire ZX at one end position. The tool base 1 is composed of one differential diameter circular frame and two same diameter circular frames. The two same diameter circular frames are installed with guide columns corresponding to the three-wing plates 7. One of the same diameter circular frames is installed with a connecting column between the same diameter circular frame and the differential diameter circular frame. The differential diameter circular frame is arranged at the position close to the rear base 4. The three-wing plates 7 are slidingly connected on the guide columns through the sleeves.

[0020] Basic principle: For copper-clad steel wire, the main process involves the twisting of the busbar MX and the daughter wire ZX. The daughter wire ZX is evenly twisted onto the busbar MX to form a complete composite wire. This can be understood by referring to the working principle of a conventional wire bundling machine, or by referring to... Figure 1 and Figure 2 MX passes through the tooling frame 5 horizontally via the traction device, ensuring that MX and the center point of the tooling frame 5 are on the same horizontal axis. ZX mainly passes through the outer edge of the tooling frame 5. During this process, MX is continuously pulled and moved, while multiple ZX are continuously wound around MX by the continuous rotation of the tooling frame 5. This part is the conventional twisting principle. Figure 1 The reel holder 6 is used to hold the reel of ZX. ZX is pulled out from the reel and passes through the three-wing plate 7, and refers to... Figure 4 and Figure 5 ZX will be transmitted through the guide wheel assembly 12 and pass through another circular frame of the same diameter and a circular frame of different diameters in sequence. Finally, ZX will gather at the rear base 4 to complete the twisting. The rotation process of the tooling frame 5 can be referred to Figure 3 The first-order drive structure 2 in the text is essentially based on the gear transmission principle.

[0021] Example 2: Based on Example 1, an improved explanation of the linear transmission process of ZX by the three-wing plate is provided: A passive hydraulic cylinder 8 is installed at one end of the guide post corresponding to the reel frame 6, and a rubber retaining sleeve 3 is slidably installed at the other end corresponding to the rear base 4. A hydraulic rod structure is formed between the sleeve in the three-phase wing plate 7 and the passive hydraulic cylinder 8. A cooperating hydraulic sleeve 9 is installed at one end of the passive hydraulic cylinder 8. The interior of the cooperating hydraulic sleeve 9 is connected to the interior oil cavity of the passive hydraulic cylinder 8. An electrical connector group 14 and a spring 13 are installed inside the cooperating hydraulic sleeve 9. A buzzer 10 corresponding to the electrical connector group 14 is installed outside the cooperating hydraulic sleeve 9. One of the three-phase wing plates 7... The sleeve is slidably connected to one of the guide posts and the sleeve is set in the middle position. The other two sleeves of the three-wing plate 7 are slidably connected to the guide posts at adjacent positions and the sleeves are set in the bidirectional side position. The middle position is located in the middle position of the two bidirectional side positions and is equipped with a spring 11. The sub-line ZX passes through the reel frame 6 and one of the circular frames of the same diameter and passes through the reversing guide wheel group 12. The reversing guide wheel group 12 is inclined in the direction close to the reel frame 6. The sub-line ZX passing through the reversing guide wheel group 12 is in the shape of an outward curved arch along the outer wall close to the circular frame of the same diameter.

[0022] Solution Description: The key content of this invention lies in the three-phase wing plate 7. In conventional stranding processes, the structure is relatively simple. This invention mainly optimizes and improves the wire conduction process between two circular frames of the same diameter in ZX, while not improving the wire conduction process between circular frames of the same diameter and those of different diameters. Specifically, it is manifested as follows: S1: ZX is pulled out from the winding wheel, directly through one of the same diameter circular frame and through another same diameter circular frame, the ZX between the two in the conventional line transmission process remains relatively horizontal, but referring to Figure 5 , ZX will pass through the reversing guide wheel set 12 when passing through the three-wing plate 7, referring to Figure 9 for explanation, the ZX between the two same diameter circular frames is not kept horizontal, but curved and arched outward in the direction close to the outer wall of the tool frame 5, the purpose of which is to ensure that the ZX between the two same diameter circular frames is in a relatively taut state to avoid relaxation problems; S2: based on S1, referring to Figure 4 and Figure 5 , the number of three-wing plates 7 is completely consistent with the number of ZX, and the three-wing plate 7 is essentially a combination of three arc-shaped mounting pieces, the end position of each arc-shaped mounting piece is equipped with a sleeve, and the sleeve is used as the sliding structure between the three-wing plate and the guide column. Further restrict the reversing guide wheel set 12 to bend in the direction close to the wire wheel frame 6, so that during the actual line transmission of ZX, ZX will generate stress on the three-wing plate 7 close to the wire wheel frame 6, so as to make the three-wing plate 7 slide on the guide column in the direction close to the wire wheel frame 6. The following is a supplementary explanation: if there is an abnormal problem in the twisting process of a sub-line relative to the rear base 4, the sub-line will generate a greater tension on the reversing guide wheel set 12, thereby increasing the stress on the three-wing plate 7, and the following is a further supplementary explanation: S2-1: referring to Figure 5 and Figure 6 , the three-wing plate 7 can slide freely on the guide column, but the guide column is provided with a rubber clamping sleeve 3 at one end close to the rear base 4, which is to limit the sliding direction of the three-wing plate 7 and to buffer and protect the sliding process of the three-wing plate 7; S2-2: secondly, a passive oil cylinder 8 is installed at the other end of the guide column, as shown in Figure 5 , one of the sleeves and the passive oil cylinder 8 form a complete oil rod structure, for example: when the three-wing plate 7 slides directly towards the wire wheel frame 6, the hydraulic oil in the oil cavity of the passive oil cylinder 8 is in a compressed state, referring to Figure 6Explain: When the hydraulic oil inside the passive cylinder 8 is compressed, it can only enter the coordinated oil sleeve 10. The essence of the electrical connector group 14 inside the coordinated oil sleeve 10 includes: dynamic contact, static contact and piston block. The piston block is installed at the lower end of the coordinated oil sleeve 10, the dynamic contact is installed at the upper end of the movable block, and the static contact is installed at the top end of the coordinated oil sleeve 10. When the piston block changes due to hydraulic oil, the dynamic contact moves in the direction of approaching the static contact under the action of the piston block until the dynamic contact and the static contact are in full contact. The dynamic contact and the static contact act as the starting switch of the buzzer 10. First, the buzzer 10 has a battery inside. When the dynamic contact and the static contact are in full contact, the circuit between the buzzer 10 and the battery is in communication, so the buzzer sends an alarm to indicate that there is an abnormal problem with a ZX. S3: Refer again Figure 4 Explain: Two adjacent guide columns are needed to maintain the sliding process of a single three-wing plate 7, but according to the state of the three-wing plate 7 presenting a three-pronged arc shape, it is necessary to ensure that each three-wing plate 7 is staggered, the essence of which is that a single sleeve in one three-wing plate 7 is located between the two sleeves in another three-wing plate 7, specifically corresponding to the middle position and the two-way side position. The middle position mainly indicates a single sleeve in the three-wing plate 7, while the two-way side position indicates the other two sleeves, and the sleeves in the middle position and the two-way side position are provided with spring one 11. To explain this: when the three-wing plate 7 at a certain position slides, the sleeves and spring one 11 will also indirectly transmit to the three-wing plate 7 at another adjacent position. Each three-wing plate 7 in the tool frame 5 is staggered, which can balance the tension changes in a ZX by dispersing to avoid affecting the overall production efficiency, but when there is a significant change in tension in a ZX, it can be discovered in time through the buzzer.

[0023] Example three: for the twisting process of ZX and MX, supplementary explanation of the rear base is proposed: The rear base 4 is provided with a motor 16, a gear set 19 is arranged between the output end position of the motor 16 and one end position of the wire pressing sleeve 17, the wire pressing sleeve 17 is rotatably connected to the rear base 4 through the motor 16 and the gear set 19, a push rod 15 is installed on the rear base 4, a pressing sleeve 18 matched with the outer wall of the wire pressing sleeve 17 is installed at the output shaft end position of the push rod 15, a gear groove is formed in the outer wall of the same diameter circular frame, and an annular sliding groove assembly is arranged between the same diameter circular frame and the tool base 1. A first drive structure 2 corresponding to the annular sliding groove assembly and the gear groove is arranged in the tool base 1.

[0024] Scheme explanation: refer to Figure 7 and Figure 8, MX completely passes through the inside of the wire pressing sleeve 17 and is not disturbed, while the ZX can be pressed by the wire pressing opening in the wire pressing sleeve 17, so that the ZX is completely attached to the MX, and it is necessary to ensure that the rotation range of the wire pressing sleeve 17 and the tool base 5 is completely consistent, the purpose is to ensure the twisting degree of the ZX relative to the MX, and it is necessary to make a supplementary description by referring to Figure 7 It is necessary to make a supplementary description that the wire pressing sleeve 17 is externally provided with a pressing sleeve 18, and the wire pressing sleeve 17 essentially belongs to the expansion structure, a plurality of grooves are formed on the outside of the wire pressing sleeve 17, first, the wire pressing sleeve 17 is driven to rotate in a certain direction by the motor 16, when an abnormal problem occurs, first, the traction speed of the MX can be reduced or the traction process of the MX is temporarily stopped, second, the wire pressing sleeve 17 is further pressed by the reverse movement of the pressing sleeve 18 to further press the ZX and the MX; It is necessary to make a supplementary description that the wire pressing sleeve 17 is externally provided with a pressing sleeve 18, and the wire pressing sleeve 17 essentially belongs to the expansion structure, a plurality of grooves are formed on the outside of the wire pressing sleeve 17, first, the wire pressing sleeve 17 is driven to rotate in a certain direction by the motor 16, when an abnormal problem occurs, first, the traction speed of the MX can be reduced or the traction process of the MX is temporarily stopped, second, the wire pressing sleeve 17 is further pressed by the reverse movement of the pressing sleeve 18 to further press the ZX and the MX;

[0025] In summary: based on the basic twisting principle of the conventional sub-wire and the bus, first, the wire transmission process of the sub-wire ZX is improved by the three wing plates, second, the twisting process of the sub-wire ZX relative to the bus MX is optimized twice, the essence is that the three wing plates are used as the wire transmission platform of the ZX, the tension change in the wire transmission process of the ZX is used as the basis, the tension-hydraulic-electricity conversion process is used to realize the real-time sensing of the wire transmission process of the ZX and the buzzer is used to send an alarm signal, the purpose is to realize the real-time control of the transmission degree of the ZX and monitor the overall twisting process, so as to avoid the influence on the overall twisting production efficiency caused by the failure to find abnormal problems in time, second, the wire pressing sleeve is used to "strengthen" the twisting process between the ZX and the MX, and does not interfere with the twisting process.
