Description

Technical Field

[0001] The invention relates to the technical field of welding wire production devices, and in particular to an anti-breaking twisting device used for welding wire production. Background Art

[0002] The welding wire twisting device is used to produce cable-type welding wire formed by twisting multiple welding wires. This type of welding wire is usually used in applications that require higher strength, better conductivity or specific welding processes. Compared with single-strand welding wire, it has better flexibility, more uniform current distribution and higher welding efficiency. During production, a central welding wire is usually used as the core, and multiple spiral welding wires are evenly distributed on the periphery for twisting.

[0003] A Chinese patent document with publication number CN117773416B discloses a welding wire production and twisting device, which includes a wiring mechanism, a winding mechanism, a twisting mechanism and a tensioning mechanism. When in use, the raw materials of the central welding wire and the spiral welding wire are placed on the wiring mechanism, and the central welding wire and the spiral welding wire are passed through the first clamping assembly, the second clamping assembly, the twisting mechanism and the winding mechanism in sequence; the patent arranges the first clamping assembly and the second clamping assembly to alternately clamp the central welding wire or the spiral welding wire passed through, so that the clamping force of the central welding wire or the spiral welding wire on the welding wire gradually increases during the process of being pulled out, thereby making the welding wire always in a tensioned state; however, in actual use, as the use time gradually increases, the first clamping assembly and the second clamping assembly will gradually wear out, thereby reducing the friction between the first clamping assembly and the second clamping assembly and the welding wire (even causing the first clamping assembly and the second clamping assembly to lose contact with the welding wire), causing the welding wire to be unable to normally drive the first clamping assembly and the second clamping assembly to move, thereby causing the first clamping assembly and the second clamping assembly to be unable to provide the necessary clamping force to the welding wire, affecting the tensioning state of the welding wire, and causing the quality of the cable welding wire finally produced to be affected.

[0016] When the welding wire breaks, the positioning ring and the extrusion ring move relative to each other, causing the welding wire to deform, thereby increasing the friction force on the cable when passing through the positioning ring and the extrusion ring, and maintaining the welding wire between the second guide plate and the stranding wheel in a tensioned state, thereby preventing the welding wire between the second guide plate and the stranding wheel from loosening after the welding wire breaks, thereby affecting the quality of the prepared cable welding wire.

[0017] After the welding wire breaks, the second extrusion block and the second fixing block cooperate with each other to clamp and fix the welding wire and bend the welding wire, thereby increasing the resistance to the movement of the welding wire, thereby preventing the welding wire wound on the winding roller from loosening freely due to loss of tension after the welding wire breaks, causing the welding wire to be pulled near the winding roller, and even causing the welding wire to mix with the relaxed welding wire, affecting the subsequent wiring process and thus affecting the overall work efficiency.

DETAILED DESCRIPTION

[0020] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this document are only for the positions of the structures shown in the corresponding drawings. The serial numbers assigned to the components in this document, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0021] Embodiment 1: A pull-off-proof twisting device for welding wire production, such as Figure 1-Figure 6As shown, it includes a support frame 1, a stranding wheel 101 is arranged on one side of the support frame 1, a plurality of winding rollers 2 are arranged on the upper side of the support frame 1, a first guide plate 3 and a second guide plate 5 are fixedly connected to the upper side of the support frame 1, and the first guide plate 3 and the second guide plate 5 are both provided with through holes whose number is the same as the winding roller 2 and are used for the welding wire to pass through; a fixed plate 4 is fixedly connected to the upper side of the support frame 1, and the fixed plate 4 is located between the first guide plate 3 and the second guide plate 5; a mounting shell 6, the number of which is the same as the number of through holes on the first guide plate 3, and both are embedded in the fixing plate 4, and two symmetrically distributed first fixing blocks 601 are fixedly connected inside the mounting shell 6, and the first fixing blocks 601 are slidably connected to the connecting plate 16, and the connecting plate 16 and the adjacent first fixing blocks 601 are connected. A first tension spring is arranged between them, and the connecting plate 16 is slidably connected with the moving block 7. The opposite sides of the two moving blocks 7 in the same mounting shell 6 are slidably connected with friction blocks 8. A second tension spring is fixedly connected between the friction block 8 and the adjacent moving block 7. The elastic coefficient of the second tension spring on the friction block 8 is greater than the elastic coefficient of the first tension spring on the first fixed block 601, which is used to limit the movement sequence of the friction block 8 and the moving block 7. The interior of the mounting shell 6 is slidably connected with two symmetrically distributed first extrusion blocks 9. The moving block 7 is provided with an inclined surface, and the first extrusion block 9 is used to extrude the moving block 7; the clamping components, the number of which is consistent with the number of the mounting shells 6, are respectively arranged on adjacent mounting shells 6, and the clamping components are used to change the distance between the opposite sides of the symmetrically distributed moving blocks 7.

[0022] In the above scheme, the stranding wheel 101 is located on the right side of the support frame 1, and is driven to rotate by the existing driving device; the specific number of winding rollers 2 can be specifically selected by the staff, and five are used as an example in the figure and the text, and one of the five winding rollers 2 is wound with the main welding wire, and the other four winding rollers 2 are wound with winding welding wires (the auxiliary welding wire is used as an example below); the first guide plate 3 is located on the right side of the winding roller 2, and the second guide plate 5 is located on the right side of the first guide plate 3. The number of through holes on the first guide plate 3 and the second guide plate 5 is represented by five as an example, and the main welding wire passes through the through hole in the middle of the first guide plate 3 and the second guide plate 5, and the four auxiliary welding wires pass through the remaining and adjacent through holes on the first guide plate 3 and the second guide plate 5 respectively; the inclination angle of the inclined surface on the moving block 7 is not greater than 45°, and when the moving block 7 moves laterally, the moving block 7 is squeezed by the adjacent first extrusion block 9 and moves longitudinally.

[0023] When it is necessary to use the present device to prepare cable welding wire, the staff will pass the main welding wire and the auxiliary welding wire through the adjacent through holes on the first guide plate 3 and the second guide plate 5 and the adjacent mounting shell 6 (the opposite sides of the two friction blocks 8 in the mounting shell 6 are in contact with the main welding wire), and finally pass the main welding wire and the auxiliary welding wire through the stranding wheel 101, and then fix the main welding wire and the auxiliary welding wire that pass through the stranding wheel 101 on the existing winding device, and then the staff will start the existing winding device and the existing driving device, and the existing driving device will drive the stranding wheel 101 to rotate, and the four auxiliary welding wires will be twisted onto the main welding wire. At the same time, the existing winding device will wind up the cable welding wire after twisting, and pull out the welding wire wound on the five winding rollers 2, so that the main welding wire and the four auxiliary welding wires move to the right relative to the adjacent winding rollers 2, respectively, so that the five winding rollers 2 are rotated under tension.

[0024] The following is a description of the movement process of the main welding wire as an example: In the process of the main welding wire moving to the right relative to the adjacent winding roller 2, the main welding wire drives the two adjacent friction blocks 8 to move to the right through friction force, and the friction blocks 8 drive the adjacent moving blocks 7 to move to the right synchronously, and stretch the first tension spring on the moving blocks 7 to store force. During the movement, the two moving blocks 7 are respectively squeezed by the adjacent first extrusion blocks 9 and drive the adjacent friction blocks 8 to approach each other (the first extrusion blocks 9 provide longitudinal extrusion force to the adjacent moving blocks 7), thereby increasing the clamping force of the two friction blocks 8 on the main welding wire, and then increasing the friction between the two friction blocks 8 and the main welding wire, so that the main welding wire between the mounting shell 6 and the stranding wheel 101 is always in a tensioned state during use, thereby ensuring the quality of the produced cable welding wire.

[0025] After the use of the device is completed, when the staff shuts down the device, the main welding wire no longer moves, and then the moving block 7, under the action of the first tension spring thereon, drives the moving block 7 and the adjacent friction block 8 to move synchronously to the left, so that the friction block 8 is separated from the main welding wire for subsequent use. As the use time of the device increases, the friction block 8 will be gradually consumed, so that the length of the friction block 8 in the front-to-back direction gradually decreases, resulting in a decrease in the friction force between the friction block 8 and the main welding wire at the initial position (even causing the friction block 8 to separate from the main welding wire), causing the main welding wire to move in the subsequent During the process, the friction block 8 cannot be driven to move normally. Therefore, during the process of the friction block 8 resetting to the left, the clamping assembly works, and the adjacent moving block 7 is driven by the clamping assembly to move, thereby reducing the distance between the opposite sides of the two adjacent moving blocks 7 in the initial position, so that the friction block 8 is always in contact with the main welding wire during normal operation, and the friction force is always maintained between the friction block 8 and the main welding wire, ensuring that the main welding wire can drive the friction block 8 to move normally during subsequent use, so that the main welding wire has a stable tension force during normal use, thereby ensuring the quality of the cable welding wire produced.

[0026] Further, such as Figure 4-Figure 7 As shown, the clamping assembly includes: a connecting sleeve 17, the number of which is consistent with the number of moving blocks 7, which is rotatably connected to the connecting plate 16, and a transmission module is arranged between the connecting sleeve 17 and the first fixed block 601; a threaded rod 18, the number of which is consistent with the number of connecting sleeves 17, which is threadedly connected to the inside of the connecting sleeve 17, the threaded rod 18 is spline-connected to the connecting plate 16, the threaded rod 18 is fitted with the adjacent moving block 7, and a third tension spring is fixed between the threaded rod 18 and the adjacent moving block 7.

[0027] In the above scheme, the connecting plate 16 is located on the left side of the adjacent moving block 7, and the connecting plate 16 is L-shaped; the transmission module is a combination of a one-way gear and a rack, wherein the one-way gear is installed on the connecting sleeve 17, and the rack is fixed to the first fixed block 601; in the process of the above-mentioned moving block 7 moving to the right, the moving block 7 drives the adjacent connecting plate 16, the adjacent connecting sleeve 17 and the adjacent threaded rod 18 to move to the right synchronously, and the connecting sleeve 17 drives the one-way gear thereon to move to the right synchronously (the rotation of the one-way gear does not drive the connecting sleeve 17 to rotate during this process), after the moving block 7 moves to contact with the adjacent first extrusion block 9, the moving block 7 on the front side moves backward along the adjacent connecting plate 16, and the moving block 7 on the rear side moves forward along the adjacent connecting plate 16, and the third pulling The spring is stretched. During the process of the above-mentioned moving block 7 being reset to the left, the one-way gear on the connecting sleeve 17 drives the connecting sleeve 17 to rotate synchronously, and then the connecting sleeve 17 drives the adjacent threaded rod 18 to move through the threaded transmission, so that the front threaded rod 18 moves backward and the rear threaded rod 18 moves forward, and then the threaded rod 18 drives the adjacent moving block 7 to move synchronously, so as to change the position of the adjacent moving block 7 and the adjacent friction block 8 after reset, so that the friction block 8 is always in contact with the main welding wire. At the same time, the electric push rod 13 is started by the remote control terminal, so that the output end of the electric push rod 13 drives the adjacent first extrusion block 9 to move synchronously, and the initial position of the first extrusion block 9 is changed, so that the first extrusion block 9 is in contact with the moving block 7, so as to ensure that after the moving block 7 is squeezed by the first extrusion block 9, the friction force between the friction block 8 and the main welding wire is ensured.

[0028] Further, such as Figure 4-Figure 7As shown, the clamping assembly also includes: an intercepting plate 10, which is fixed in the adjacent mounting shell 6; an extrusion plate 11, which is slidably connected to the intercepting plate 10, and the extrusion plate 11 is provided with a through hole. When the friction block 8 moves relative to the adjacent moving block 7, the friction block 8 squeezes the adjacent extrusion plate 11; a hydraulic telescopic rod 12, which has two symmetrically distributed ones, both of which are fixed to the intercepting plate 10, and the telescopic end of the hydraulic telescopic rod 12 is in contact with the extrusion plate 11; an electric push rod 13, which has two symmetrically distributed ones, both of which are slidably connected to the adjacent mounting shell 6, and the telescopic end of the electric push rod 13 is fixed to the adjacent first extrusion block 9, and a spring is fixed between the electric push rod 13 and the adjacent mounting shell 6; a first liquid storage shell 14, which has two symmetrically distributed ones, both of which are fixed to the adjacent mounting shell 6, and the first liquid storage shell 14 is connected to the fixed part of the adjacent hydraulic telescopic rod 12 through a hose, and the first piston rod 15 is slidably connected to the interior of the first liquid storage shell 14, and the electric push rod 13 is provided with a first blind hole for the first piston rod 15 to slide.

[0029] In the above scheme, the intercepting plate 10 is located on the right side of the adjacent first extrusion block 9; the extrusion plate 11 is located in the middle of the intercepting plate 10, and the length of the extrusion plate 11 in the front-to-back direction is greater than the maximum distance between the two adjacent friction blocks 8 at the initial time; the fixed part of the hydraulic telescopic rod 12 is filled with hydraulic oil; there are two electric push rods 13 symmetrically distributed front and back, and the electric push rods 13 are used to drive the adjacent first extrusion blocks 9 to move, and the first blind hole on the electric push rod 13 is located on its fixed part; the spring on the electric push rod 13 is in a compressed state at the initial time, and the electric push rod 13 is connected to the remote control terminal network; the first liquid storage shell 14 and the hose thereon both store hydraulic oil; initially, the left end of the first piston rod 15 is located in the first blind hole of the adjacent electric push rod 13.

[0030] In the above-mentioned process of fixing the welding wire, the welding wire is passed through the through hole on the adjacent extrusion plate 11. The following is described by taking the moving process of the main welding wire as an example: In the process of the two moving blocks 7 being driven to the right by the main welding wire, after the two moving blocks 7 move to the right and contact the left side of the intercepting plate 10, the two moving blocks 7 stop moving. At this time, the distance between the two moving blocks 7 reaches the minimum value, and the friction between the two friction blocks 8 and the main welding wire reaches the maximum value synchronously. At this time, if the friction force is less than the tension of the first tension spring on the friction block 8, the main welding wire can move normally. If the friction force is greater than the tension of the first tension spring on the friction block 8, the main welding wire drives the two friction blocks 8 to move to the right, and the two friction blocks 8 squeeze the left side of the squeezing plate 11, and then the squeezing plate 11 squeezes the telescopic ends of the two hydraulic telescopic rods 12, and the hydraulic oil in the fixed part of the hydraulic telescopic rod 12 is squeezed into the adjacent first liquid storage shell 14 through the adjacent hose.

[0031] The following is described by taking the moving process of the front hydraulic telescopic rod 12 as an example: After the hydraulic oil in the fixed part of the hydraulic telescopic rod 12 is transported to the first liquid storage shell 14, the first piston rod 15 moves to the right due to the extrusion force, so that the first piston rod 15 gradually moves out of the first blind hole of the electric push rod 13. After the first piston rod 15 loses contact with the electric push rod 13, the first piston rod 15 no longer limits the electric push rod 13. At this time, the electric push rod 13 moves forward under the action of the spring thereon, thereby driving the first extrusion block 9 to move forward synchronously, so that the first extrusion block 9 no longer squeezes the moving block 7, thereby making the moving block 7 and the friction block 8 stay away from the main welding wire, so as to avoid excessive friction on the main welding wire, which causes the main welding wire to be deformed or even broken during the process of being pulled out, resulting in the final quality of the produced cable welding wire being affected.

[0032] After the two first extrusion blocks 9 are moved, the staff shuts down the device and inspects the two friction blocks 8 to determine whether the above situation occurs because the friction coefficient of the friction block 8 is too large (which directly leads to excessive friction between the friction block 8 and the main welding wire) or the thickness of the first extrusion block 9 is too large (which leads to an increase in the relative movement distance of the two moving blocks 7, and excessive friction between the friction block 8 and the main welding wire). After the inspection is completed, the staff resets the two first extrusion blocks 9 for subsequent continued use.

[0033] Embodiment 2: Based on embodiment 1, Figure 8 and Fig. 9 As shown, it also includes: a protective mechanism, the number of which is consistent with the number of winding rollers 2, the protective mechanism is arranged between the support frame 1 and the second guide plate 5, the protective mechanism is used to tension the welding wire when the welding wire is broken, and the protective mechanism includes: a mounting plate 19, fixedly connected to the side of the second guide plate 5 close to the fixed plate 4; a positioning ring 20, fixedly connected to the mounting plate 19 through a connecting rod; a first moving rod 201, slidably connected to the mounting plate 19, and a fourth tension spring is fixedly connected between the first moving rod 201 and the mounting plate 19; an extrusion ring 21, fixedly connected to the side of the first moving rod 201 away from the support frame 1; a trigger assembly, arranged on the mounting plate 19, and the trigger assembly is used to change the position of the first moving rod 201.

[0034] In the above scheme, the mounting plate 19 is located on the left side of the second guide plate 5; the positioning ring 20 and the adjacent extrusion ring 21 are both located above the adjacent mounting plate 19, and the main welding wire and the auxiliary welding wire pass through the adjacent positioning ring 20 and the adjacent extrusion ring 21 respectively; the fourth tension spring on the first moving rod 201 is in a stretched state at the beginning; when the welding wire is broken, by changing the position of the extrusion ring 21, the welding wire between the extrusion ring 21 and the adjacent positioning ring 20 is squeezed and deformed by the extrusion ring 21, so that the welding wire between the two maintains a certain tension.

[0035] Further, such as Fig. 9As shown, the positioning ring 20 does not contact the adjacent extrusion ring 21, and the distance between the two is smaller than the diameter of the welding wire, which is used to increase the extrusion force of the extrusion ring 21 and the adjacent positioning ring 20 on the welding wire between them after the extrusion ring 21 moves, thereby increasing the friction force of the welding wire between them.

[0036] Further, such as Figure 8 and Fig. 9 As shown, the trigger assembly includes: a liquid storage tube 22, fixedly connected to the adjacent mounting plate 19; a second movable rod 23, slidably connected to the inside of the liquid storage tube 22, and a fifth tension spring is fixedly connected between the second movable rod 23 and the liquid storage tube 22; a movable ring 24, fixedly connected to the second movable rod 23, and the movable ring 24 is located between the extrusion ring 21 and the fixed plate 4; a second liquid storage shell 25, fixedly connected to the adjacent mounting plate 19, and a second piston rod 26 is slidably connected in the second liquid storage shell 25, the first movable rod 201 is provided with a second blind hole for the adjacent second piston rod 26 to slide, and the second liquid storage shell 25 is connected to the liquid storage tube 22 through a hose.

[0037] In the above scheme, the parts shown in the figure are all in the moved state, not the initial position; hydraulic oil is stored in the liquid storage tube 22; the moving ring 24 is located on the left side of the second moving rod 23; hydraulic oil is stored in the second liquid storage shell 25 and the hose thereon.

[0038] At present, in the process of producing cable welding wire, if the welding wire breaks, the staff can quickly shut down the production device by pressing the emergency stop button. However, at the moment when the welding wire breaks, the tension of the welding wire has changed, which causes the tightness of the cable welding wire that has been twisted near the break to be affected, thereby affecting the overall strength and stability of the welding wire. The present invention solves this problem by the following measures: The following is described using the main welding wire as an example: In the process of fixing the welding wire, the main welding wire is passed through the positioning ring 20, the extrusion ring 21 and the moving ring 24 in the middle. At this time, the main welding wire between the fixed plate 4 and the second guide plate 5 will be in an arc shape due to its own gravity. Then, the staff manually tightens the main welding wire between the fixed plate 4 and the second guide plate 5, that is, straightens the arc-shaped main welding wire, and manually moves the extrusion ring 21 upward to a position flush with the positioning ring 20. In this process, the extrusion ring 21 drives the first moving rod 201 to move upward synchronously, so that the first The fourth tension spring on the moving rod 201 is stretched to store force. At the same time, in the process of the main welding wire gradually changing to a tensioned state, the main welding wire squeezes the adjacent moving ring 24, so that the moving ring 24 drives the adjacent second moving rod 23 to move upward. While the fifth tension spring in the liquid storage tube 22 is stretched, the second moving rod 23 also draws the hydraulic oil in the second liquid storage shell 25 into the liquid storage tube 22 through the hose, so that the second piston rod 26 moves to the left and gradually inserts into the second blind hole of the first moving rod 201, thereby limiting the first moving rod 201.

[0039] After the main welding wire between the fixed plate 4 and the second guide plate 5 is in a tensioned state, the movable ring 24 moves upward to the limit position, and the second liquid storage shell 25 moves leftward to the limit position, and then the staff can prepare the cable welding wire according to the above operation.

[0040] During the preparation of the cable welding wire, if the main welding wire located between the fixed plate 4 and the second guide plate 5 breaks (the main welding wire after breaking is divided into two parts, left and right), the main welding wire no longer squeezes the movable ring 24, and the movable ring 24 moves downward under the action of the fourth tension spring in the liquid storage tube 22, and the hydraulic oil in the liquid storage tube 22 is pressurized and moves to the second liquid storage shell 25 through the hose, so that the second piston rod 26 moves to the right under the extrusion force.

[0041] When the fourth tension spring in the above-mentioned liquid storage tube 22 recovers to the unstretched state, the movable ring 24 moves downward to the extreme position. At this time, the second piston rod 26 loses contact with the first movable rod 201, and the first movable rod 201 moves downward under the action of the fourth tension spring thereon, so that the positioning ring 20 and the extrusion ring 21 are misaligned, thereby causing the main welding wire to deform at the position of the positioning ring 20 and the extrusion ring 21, increasing the friction force on the cable in the process of passing through the positioning ring 20 and the extrusion ring 21, and maintaining the main welding wire between the second guide plate 5 and the stranding wheel 101 in a tensioned state, thereby avoiding the main welding wire between the second guide plate 5 and the stranding wheel 101 from loosening after the main welding wire breaks, thereby affecting the quality of the prepared cable welding wire.

[0042] The staff then shut down the device, rejoined the broken welding wire, and searched for the cause of the broken welding wire. After eliminating the cause, the staff continued to prepare the cable welding wire according to the above operations.

[0043] Embodiment 3: Based on embodiment 2, Figure 2 , Figure 3 and Fig.10 As shown, it also includes: a clamping assembly, the number of which is consistent with the number of mounting shells 6, which are respectively arranged on adjacent mounting shells 6, and the clamping assembly is used to fix the broken welding wire when the welding wire is broken. The clamping assembly includes: a second fixed block 27, which is rotatably connected to the adjacent mounting shell 6, and a torsion spring is fixedly connected between the second fixed block 27 and the adjacent mounting shell 6; a second extrusion block 28, which is slidably connected to the adjacent mounting shell 6; a spring telescopic rod 29, which is fixedly connected between the second fixed block 27 and the second extrusion block 28; a third liquid storage shell 30, which is fixedly connected to the adjacent mounting shell 6, and the third liquid storage shell 30 is connected to the adjacent liquid storage tube 22 through a hose, and a third piston rod 31 is slidably connected in the third liquid storage shell 30, and the third piston rod 31 passes through the adjacent mounting shell 6 and is slidably connected thereto, and the third piston rod 31 is used to limit the second extrusion block 28.

[0044] In the above scheme, Fig.10 What is shown is the initial position of the above parts. Figure 2 and Figure 3 What is shown are the positions of the above-mentioned parts after movement; initially, the telescopic end of the spring telescopic rod 29 is in a retracted state, and the spring telescopic rod 29 has not stored force at this time; hydraulic oil is stored in the interior of the third liquid storage shell 30 and in the hose thereon, and initially the lower end of the third piston rod 31 is located at the upper part of the adjacent mounting shell 6.

[0045] The following is a description of the movement process of the main welding wire as an example: Before the above-mentioned staff fixes the main welding wire, the staff first rotates the second fixing block 27 counterclockwise, and the second fixing block 27 drives the second extrusion block 28 to rotate synchronously through the spring telescopic rod 29, and the torsion spring on the second fixing block 27 is twisted and stored. After the second fixing block 27 rotates 90°, the staff stops rotating the second fixing block 27 (at this time, the second extrusion block 28 is located behind the second fixing block 27), pulls the second extrusion block 28 backward, and during the movement of the second extrusion block 28, the telescopic end of the spring telescopic rod 29 is synchronously pulled out, and the spring telescopic rod 29 is stored. Force, then the staff fixes the main welding wire according to the above operation. In the process of the second moving rod 23 moving upward, the hydraulic oil in the second liquid storage shell 25 moves into the liquid storage tube 22 through the soft pass, and the third piston rod 31 moves downward. When the second moving rod 23 stops moving upward, the third piston rod 31 stops moving downward synchronously. At this time, the lower end of the third piston rod 31 is located in the mounting shell 6, and the lower end of the third piston rod 31 is located at the front side of the second extrusion block 28, which limits the second extrusion block 28, and then limits the second fixed block 27 and the spring telescopic rod 29.

[0046] After the above-mentioned main welding wire breaks, the hydraulic oil in the liquid storage tube 22 moves into the second liquid storage shell 25, and at the same time moves into the third liquid storage shell 30 through the hose, so that the third piston rod 31 moves upward due to the extrusion force. When the above-mentioned second moving rod 23 moves downward to the limit position, the third piston rod 31 moves upward to the limit position synchronously. At this time, the third piston rod 31 is no longer in contact with the second extrusion block 28, so that the second fixed block 27, under the action of the torsion spring thereon, drives the second extrusion block 28 to rotate synchronously clockwise through the spring telescopic rod 29, until the torsion spring on the second fixed block 27 returns to the uncharged state, and the second fixed block 27 rotates clockwise by 90°.

[0047] During the clockwise rotation of the above-mentioned second fixed block 27, the telescopic end of the spring telescopic rod 29 drives the second extrusion block 28 to move in the direction close to the second fixed block 27 during the rotation with the second fixed block 27, thereby reducing the distance between the second extrusion block 28 and the second fixed block 27, and the second extrusion block 28 and the second fixed block 27 cooperate with each other to clamp and fix the left part of the main welding wire, and at the same time, the second extrusion block 28 and the second fixed block 27 cooperate with each other to bend the left part of the main welding wire, further increasing the fixing force of the main welding wire, that is, increasing the resistance of the left part of the main welding wire to move leftward, thereby preventing the main welding wire wound on the winding roller 2 from freely relaxing due to the loss of tension after the main welding wire breaks, causing the left end of the main welding wire to be pulled near the winding roller 2, and even causing the left end of the main welding wire to mix with the relaxed main welding wire, affecting the subsequent wiring process, thereby affecting the overall work efficiency.

[0048] After the above-mentioned main welding wire breaks, the staff will shut down the device, connect the main welding wire, reset the above-mentioned parts to the initial position, and then continue to prepare the required cable welding wire according to the above-mentioned operations.

[0049] Further, such as Figure 2 and Fig.10 As shown, it also includes: a limit rod 32, the number of which is the same as the number of the mounting shells 6, which pass through and are slidably connected to the adjacent mounting shells 6 respectively, the limit rod 32 is used to limit the second extrusion block 28 after movement, and a sixth tension spring is arranged between the limit rod 32 and the adjacent mounting shell 6; the part of the limit rod 32 located in the mounting shell 6 is provided with an inclined surface, and the angle between the inclined surface on the limit rod 32 and the horizontal plane is not greater than 45°, which is used to reduce the resistance when the second extrusion block 28 contacts the limit rod 32, and there is damping between the fixed part and the telescopic end of the spring telescopic rod 29, which is used to reduce the speed when the telescopic end of the spring telescopic rod 29 moves into its fixed part, and the elastic coefficient of the spring telescopic rod 29 is greater than the elastic coefficient of the sixth tension spring on the limit rod 32.

[0050] The following description is made by taking the moving process of the middle limit rod 32 as an example: Before the above-mentioned staff member rotates the second fixed block 27 counterclockwise, the staff member pulls the limit rod 32 upward (so that the sixth tension spring on the limit rod 32 is stretched and stored), so that the limit rod 32 loses the limit on the second extrusion block 28. Then the staff member rotates the second fixed block 27 counterclockwise according to the above-mentioned operation, and after fixing the welding wire, releases the limit rod 32, so that the limit rod 32 is reset to the initial position under the action of the sixth tension spring thereon.

[0051] In the process that the second fixed block 27 drives the adjacent second extrusion block 28 to rotate clockwise, when the second extrusion block 28 contacts the limiting rod 32, the second extrusion block 28 squeezes the inclined surface of the limiting rod 32, so that the limiting rod 32 moves upward, and the tension spring on the limiting rod 32 is stretched and stored, until the second extrusion block 28 completely loses contact with the limiting rod 32, and the limiting rod 32 moves downward to the initial position under the action of the sixth tension spring thereon, at this time, the second extrusion block 28 is limited by the limiting rod 32, so that the second extrusion block 28 cannot be reset, thereby increasing the second extrusion block 28. 28 and the second fixing block 27 exert a fixing force on the main welding wire to prevent the main welding wire from driving the second extrusion block 28 and the second fixing block 27 to shake during the loosening process, resulting in the second extrusion block 28 and the second fixing block 27 being separated from the main welding wire. Subsequently, the staff shuts down the device and rotates the second extrusion block 28 and the second fixing block 27 counterclockwise again (the specific process refers to the movement process of the second extrusion block 28 and the second fixing block 27 in the above-mentioned process of fixing the welding wire), and then rejoins the broken welding wire to continue using the device to prepare the cable welding wire.

[0052] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
