Description

Technical Field

[0001] The present invention relates to the technical field of wire welding rod production devices, and particularly to an anti-breakage twisting device for wire welding rod production. Background Art

[0002] A wire welding rod twisting device is used to produce a cable-type wire welding rod formed by twisting multiple wire welding rods. Such a wire welding rod is usually used in applications that require higher strength, better electrical conductivity, or specific welding processes. Compared with a single-strand wire welding rod, it has better flexibility, more uniform current distribution, and higher welding efficiency. During production, usually with a central wire welding rod as the core, multiple winding wire welding rods are evenly distributed around it for twisting.

[0003] Chinese patent document with publication number CN117773416B discloses a wire welding rod production twisting device, including a wire distribution mechanism, a winding mechanism, a twisting mechanism, and a tensioning mechanism. When in use, the raw materials of the central wire welding rod and the winding wire welding rods are placed on the wire distribution mechanism, and both the central wire welding rod and the winding wire welding rods pass through the first clamping assembly, the second clamping assembly, the twisting mechanism, and the winding mechanism in sequence; this patent alternately clamps the passing central wire welding rod or winding wire welding rod through the first clamping assembly and the second clamping assembly, so that the clamping force of the two on the wire welding rod gradually increases during the process of pulling out the wire welding rod, thereby keeping the wire welding rod in a tensioned state all the time; however, during the actual use process, with the gradual increase of the use time, the first clamping assembly and the second clamping assembly will gradually wear, resulting in a decrease in the friction force between the first clamping assembly and the second clamping assembly and the wire welding rod (even causing the first clamping assembly and the second clamping assembly to lose contact with the wire welding rod), so that the wire welding rod cannot normally drive the first clamping assembly and the second clamping assembly to move, and then the first clamping assembly and the second clamping assembly cannot provide the due clamping force to the wire welding rod, affecting the tensioned state of the wire welding rod and resulting in an impact on the quality of the finally produced cable-type wire welding rod.

[0024] A first moving rod, slidably connected to the mounting plate, and a fourth tension spring is fixedly connected between the first moving rod and the mounting plate;

[0025] An extrusion ring, fixedly connected to the side of the first moving rod away from the support frame;

[0027] As a further preferred solution, the positioning ring does not contact the adjacent extrusion ring, and the distance between the two is less than the diameter of the welding wire.

[0028] As a further preferred solution, the trigger assembly includes:

[0029] A liquid storage pipe, fixedly connected to the adjacent mounting plate;

[0030] A second moving rod, slidably connected inside the liquid storage pipe, and a fifth tension spring is fixedly connected between the second moving rod and the liquid storage pipe;

[0033] As a further preferred solution, it further includes:

[0034] The clamping assemblies, the number of which is the same as that of the mounting cases, are respectively arranged on adjacent mounting cases. The clamping assemblies are used to fix the broken welding wire when the welding wire breaks. The clamping assemblies include:

[0041] As a further preferred solution, an inclined surface is arranged on the part of the limiting rod located inside the mounting case, and the included angle between the inclined surface on the limiting rod and the horizontal plane is not greater than 45°.

[0042] The present invention has the following advantages: During the resetting process of the friction blocks, the distance between two adjacent moving blocks is reduced, so that there is always friction between the friction blocks and the main welding wire, ensuring that the main welding wire can drive the friction blocks to move normally, enabling the main welding wire to have a stable tension during normal use, thereby guaranteeing the quality of the produced cable-type welding wire. At the same time, when the friction between the friction blocks and the welding wire is too large, the friction blocks are separated from the welding wire, reducing the probability that the welding wire breaks during the pulling process due to excessive friction.

[0043] When the welding wire breaks, the positioning ring and the extrusion ring move relative to each other, driving the deformation of the welding wire, increasing the friction force on the cable during the process of passing through the positioning ring and the extrusion ring, maintaining the welding wire between the second guiding plate and the stranding wheel in a tensioned state, and preventing the welding wire between the second guiding plate and the stranding wheel from loosening after the welding wire breaks, thereby affecting the quality of the prepared cable-type welding wire.

[0044] 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, increasing the resistance to the movement of the welding wire, so as to prevent the welding wire wound on the winding roller from freely relaxing due to the loss of tension after the welding wire breaks, resulting in the welding wire being pulled to the vicinity of the winding roller, or even causing the welding wire to be mixed with the released welding wire, affecting the subsequent wiring process and thus the overall working efficiency.

Detailed implementation manner

[0056] The following further illustrates the technical solution with specific embodiments. It should be noted that: The words indicating directions such as up, down, left, and right mentioned in this article are only in terms of the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this article, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings.

[0057] Embodiment 1: An anti - breakage stranding device for wire - electrode production, as Figures 1-6 shown, includes a support frame 1. A wire 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. The upper side of the support frame 1 is fixedly connected with a first guiding plate 3 and a second guiding plate 5. Through - holes that are the same in number as the winding rollers 2 and used for the wire - electrode to pass through are arranged on both the first guiding plate 3 and the second guiding plate 5. A fixing plate 4 is fixedly connected to the upper side of the support frame 1, and the fixing plate 4 is located between the first guiding plate 3 and the second guiding plate 5. The number of mounting shells 6 is the same as the number of through - holes on the first guiding plate 3, and they are all embedded in the fixing plate 4. Two symmetrically distributed first fixing blocks 601 are fixedly connected inside the mounting shell 6. A connecting plate 16 is slidably connected to the first fixing block 601. A first tension spring is arranged between the connecting plate 16 and the adjacent first fixing block 601. A moving block 7 is slidably connected to the connecting plate 16. Friction blocks 8 are slidably connected to the opposite sides of the two moving blocks 7 in the same mounting shell 6. 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 that of the first tension spring on the first fixing block 601, which is used to limit the moving sequence of the friction block 8 and the moving block 7. Two symmetrically distributed first extrusion blocks 9 are slidably connected inside the mounting shell 6. An inclined surface is arranged on the moving block 7, and the first extrusion block 9 is used to extrude the moving block 7. Compressing assemblies, the number of which is the same as the number of mounting shells 6, are respectively arranged on the adjacent mounting shells 6, and the compressing assemblies are used to change the distance between the opposite sides of the symmetrically distributed moving blocks 7.

[0058] In the above solution, the wire stranding wheel 101 is located on the right side of the support frame 1 and is driven to rotate by an existing driving device; the specific number of winding rollers 2 can be selected by the staff. In the figure and in the text, five are taken as examples for illustration. One of the five winding rollers 2 is wound with a main welding wire, and the other four winding rollers 2 are wound with winding welding wires (hereinafter replaced by auxiliary welding wires for example); the first guiding plate 3 is located on the right side of the winding roller 2, and the second guiding plate 5 is located on the right side of the first guiding plate 3. The number of through holes on the first guiding plate 3 and the second guiding plate 5 are both taken as five for illustration. The main welding wire passes through the through holes in the middle of the first guiding plate 3 and the second guiding plate 5, and the four auxiliary welding wires respectively pass through the remaining adjacent through holes on the first guiding plate 3 and the second guiding plate 5; the inclination angle of the inclined surface on the moving block 7 is not greater than 45°. When the moving block 7 moves horizontally, the moving block 7 is longitudinally moved by the extrusion of the adjacent first pressing block 9.

[0059] When the device is needed to prepare the cable-type welding wire, the staff passes the main welding wire and the auxiliary welding wire through the adjacent through holes on the first guiding plate 3 and the second guiding plate 5 and the adjacent mounting shells 6 respectively (the opposite sides of the two friction blocks 8 in the mounting shell 6 are both in contact with the main welding wire), and finally passes the main welding wire and the auxiliary welding wire through the wire stranding wheel 101. Then, the main welding wire and the auxiliary welding wire passing through the wire stranding wheel 101 are fixed on the existing winding device. Subsequently, the staff starts the existing winding device and the existing driving device. The existing driving device drives the wire stranding wheel 101 to rotate, twists the four auxiliary welding wires onto the main welding wire, and at the same time, the existing winding device winds the completed cable-type welding wire, and pulls out the welding wires 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, and further the five winding rollers 2 are rotated by the pulling force.

[0060] The following takes the moving process of the main welding wire as an example for description:

[0061] In the process of the above-mentioned 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. The friction blocks 8 drive the adjacent moving blocks 7 to move to the right synchronously, and stretch and store energy in the first tension springs on the moving blocks 7. During the movement of the two moving blocks 7, they are respectively extruded by the adjacent first pressing blocks 9 to drive the adjacent friction blocks 8 to approach each other (the first pressing blocks 9 provide a longitudinal extrusion force to the adjacent moving blocks 7), increasing the clamping force of the two friction blocks 8 on the main welding wire, and further increasing the friction force between the two friction blocks 8 and the main welding wire, so that the main welding wire between the mounting shell 6 and the wire stranding wheel 101 is always in a tensioned state during use, ensuring the quality of the produced cable-type welding wire.

[0062] After the use of this device is completed and the staff shuts down the device, the main welding wire no longer moves. Subsequently, under the action of the first tension spring on it, the moving block 7 drives the moving block 7 and the adjacent friction block 8 to move leftward synchronously, separating the friction block 8 from the main welding wire for subsequent use. As the usage time of this device increases, the friction block 8 will be gradually consumed, resulting in a gradual reduction in the length of the friction block 8 in the front-rear direction, causing the friction force between the friction block 8 and the main welding wire at the initial position to decrease (or even causing the friction block 8 to separate from the main welding wire), resulting in the inability of the main welding wire to drive the friction block 8 to move normally during subsequent movement. Therefore, during the leftward reset process of the above-mentioned friction block 8, the pressing component works, driving the adjacent moving block 7 to move by the pressing component, reducing the distance between the adjacent sides of the two adjacent moving blocks 7 at the initial position, enabling the friction block 8 to always be in contact with the main welding wire during normal operation, and maintaining a friction force between the friction block 8 and the main welding wire at all times, ensuring that the main welding wire can drive the friction block 8 to move normally during subsequent use, enabling the main welding wire to have a stable tension during normal use, thereby guaranteeing the quality of the cable-type welding wire produced.

[0063] Further, as Figures 4-7 shown, the pressing component includes: a connecting sleeve 17, the number of which is the same as that of the moving blocks 7, rotatably connected to the connecting plate 16, and a transmission module is provided between the connecting sleeve 17 and the first fixed block 601; a threaded rod 18, the number of which is the same as that of the connecting sleeves 17, 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 in contact with the adjacent moving block 7, and a third tension spring is fixedly connected between the threaded rod 18 and the adjacent moving block 7.

[0064] In the above solution, 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, where the one-way gear is installed on the connecting sleeve 17 and the rack is fixedly connected to the first fixed block 601; during the process of the 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 synchronously to the right, and the one-way gear on the connecting sleeve 17 is driven to move synchronously to the right by the connecting sleeve 17 (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 the adjacent first extrusion block 9, the front moving block 7 moves backward along the adjacent connecting plate 16, and the rear moving block 7 moves forward along the adjacent connecting plate 16, and stretches the third tension spring on the adjacent threaded rod 18. During the process of the moving block 7 resetting 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 screw 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 to change the positions of the adjacent moving block 7 and the adjacent friction block 8 after resetting, so that the friction block 8 always contacts the main welding wire. At the same time, the electric push rod 13 is started by the remote control terminal, and the output end of the electric push rod 13 drives the adjacent first extrusion block 9 to move synchronously, changing the initial position of the first extrusion block 9 so that the first extrusion block 9 contacts the moving block 7 to ensure the friction force between the friction block 8 and the main welding wire after the moving block 7 is extruded by the first extrusion block 9.

[0065] Further, as Figures 4-7 shown, the pressing assembly further includes: an intercepting plate 10 fixedly connected to the adjacent mounting shell 6; an extrusion plate 11 slidably connected to the intercepting plate 10, the extrusion plate 11 is provided with a through hole, and when the friction block 8 moves relative to the adjacent moving block 7, the friction block 8 extrudes the adjacent extrusion plate 11; two symmetrically distributed hydraulic telescopic rods 12, both fixedly connected to the intercepting plate 10, and the telescopic ends of the hydraulic telescopic rods 12 are in contact with the extrusion plate 11; two symmetrically distributed electric push rods 13, both slidably connected to the adjacent mounting shell 6, the telescopic ends of the electric push rods 13 are fixedly connected to the adjacent first extrusion block 9, and a spring is fixedly connected between the electric push rod 13 and the adjacent mounting shell 6; two symmetrically distributed first liquid storage shells 14, both fixedly connected to the adjacent mounting shell 6, the first liquid storage shell 14 is communicated with the fixed part of the adjacent hydraulic telescopic rod 12 through a hose, and a first piston rod 15 is slidably connected inside 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.

[0066] In the above solution, the interception 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 interception plate 10, and the length of the extrusion plate 11 in the front-back direction is greater than the maximum distance between 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 in the front-back direction, and the electric push rod 13 is used to drive the adjacent first extrusion block 9 to move. 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 through a network; both the first liquid storage shell 14 and the hose on it store hydraulic oil; at the initial time, the left end of the first piston rod 15 is located in the first blind hole of the adjacent electric push rod 13.

[0067] In the process of fixing the welding wire above, pass the welding wire through the through hole on the adjacent extrusion plate 11. The following takes the moving process of the main welding wire as an example for description:

[0068] In the process of the main welding wire driving the two moving blocks 7 to move to the right above, after the two moving blocks 7 move to the right and contact the left side surface of the interception 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 at the same time, the friction force between the two friction blocks 8 and the main welding wire synchronously reaches the maximum value. At this time, if the friction force is less than the pulling force 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 pulling force 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 surface of the extrusion plate 11, thereby causing the extrusion plate 11 to squeeze the telescopic ends of the two hydraulic telescopic rods 12, and squeezing the hydraulic oil in the fixed part of the hydraulic telescopic rod 12 into the adjacent first liquid storage shell 14 through the adjacent hose.

[0069] The following takes the moving process of the front hydraulic telescopic rod 12 as an example for description:

[0070] After the hydraulic oil in the fixed part of the hydraulic telescopic rod 12 above is transported into the first liquid storage shell 14, the first piston rod 15 moves to the right under the extrusion force, causing the first piston rod 15 to gradually move 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 on it, 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 causing the moving block 7 and the friction block 8 to move away from the main welding wire, avoiding excessive friction force on the main welding wire, resulting in deformation or even fracture of the main welding wire during the pulling process, and affecting the final quality of the produced cable-type welding wire.

[0071] After the above two first extrusion blocks 9 move, the staff shuts down the device, and the staff checks the two friction blocks 8 to determine whether it is because the friction coefficient of the friction block 8 is too large (directly resulting in too large a frictional force between the friction block 8 and the main welding wire) or the thickness of the first extrusion block 9 is too large (resulting in an increase in the relative movement distance of the two moving blocks 7, and thus too large a frictional force between the friction block 8 and the main welding wire), which causes the above situation. After the inspection is completed, the staff resets the two first extrusion blocks 9 for subsequent continued use.

[0072] Embodiment 2: On the basis of Embodiment 1, as Figure 8 and Figure 9 shown, it further includes: a protection mechanism, the number of which is the same as the number of winding rollers 2. The protection mechanism is arranged between the support frame 1 and the second guiding plate 5. The protection mechanism is used to tension the welding wire when the welding wire is broken. The protection mechanism includes: a mounting plate 19, fixedly connected to one side of the second guiding plate 5 close to the fixing 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 one side of the first moving rod 201 away from the support frame 1; a triggering component, arranged on the mounting plate 19, and the triggering component is used to change the position of the first moving rod 201.

[0073] In the above solution, the mounting plate 19 is located on the left side of the second guiding 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 respectively pass through the adjacent positioning ring 20 and the adjacent extrusion ring 21; the fourth tension spring on the first moving rod 201 is in a stretched state initially; 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 deformed by the extrusion of the extrusion ring 21, so as to keep a certain tension force on the welding wire between the two.

[0074] Furthermore, as Figure 9 shown, the positioning ring 20 does not contact the adjacent extrusion ring 21, and the distance between the two is less 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 the two after the extrusion ring 21 moves, and thus increase the frictional force between the two and the welding wire between the two.

[0075] Furthermore, as Figure 8 and Figure 9As 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.

[0076] 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.

[0077] 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:

[0078] The following is described using the main welding wire as an example:

[0079] 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.

[0080] After the main welding wire located between the fixed plate 4 and the second guiding plate 5 is in a tensioned state, the moving ring 24 moves upward to the limit position, and at the same time, the second liquid storage shell 25 moves leftward to the limit position. Subsequently, the operator can prepare the cable-type welding wire according to the above operations.

[0081] During the preparation of the cable-type welding wire, if the main welding wire located between the fixed plate 4 and the second guiding plate 5 breaks (the broken main welding wire is divided into left and right parts), the main welding wire no longer presses the moving ring 24. As a result, the moving ring 24 moves downward under the action of the fourth spring in the liquid storage tube 22, and the hydraulic oil in the liquid storage tube 22 is pressured to move through the hose to the second liquid storage shell 25, so that the second piston rod 26 moves rightward under the extrusion force.

[0082] When the fourth spring in the above-mentioned liquid storage tube 22 returns to the non-stretched state, the moving ring 24 moves downward to the limit position. At this time, the second piston rod 26 loses contact with the first moving rod 201. As a result, the first moving rod 201 moves downward under the action of the fourth spring thereon, causing the positioning ring 20 and the extrusion ring 21 to be misaligned, thereby driving the main welding wire to deform at the positions of the positioning ring 20 and the extrusion ring 21, increasing the friction force on the cable during the process of passing through the positioning ring 20 and the extrusion ring 21, and thus maintaining the main welding wire between the second guiding plate 5 and the stranding wheel 101 in a tensioned state, preventing the main welding wire between the second guiding plate 5 and the stranding wheel 101 from loosening after the main welding wire breaks, and thus affecting the quality of the prepared cable-type welding wire.

[0083] Subsequently, the operator shuts down the device, reconnects the broken welding wire, and searches for the cause of the welding wire breakage. After eliminating the cause, the operator continues to prepare the cable-type welding wire according to the above operations.

[0084] Embodiment 3: On the basis of Embodiment 2, as Figure 2 、 Figure 3 and Figure 10 shown, it further includes: a clamping assembly, the number of which is the same as the number of the mounting shells 6, and is respectively arranged on adjacent mounting shells 6. The clamping assembly is used to fix the broken welding wire when the welding wire breaks. The clamping assembly includes: a second fixing block 27, rotatably connected to the adjacent mounting shell 6, and a torsion spring is fixedly connected between the second fixing block 27 and the adjacent mounting shell 6; a second extrusion block 28, slidably connected to the adjacent mounting shell 6; a spring telescopic rod 29, fixedly connected between the second fixing block 27 and the second extrusion block 28; a third liquid storage shell 30, fixedly connected to the adjacent mounting shell 6, and the third liquid storage shell 30 is communicated with the adjacent liquid storage tube 22 through a hose. A third piston rod 31 is slidably connected in the third liquid storage shell 30. The third piston rod 31 passes through the adjacent mounting shell 6 and is slidably connected thereto. The third piston rod 31 is used to limit the second extrusion block 28.

[0085] In the above solution,Figure 10 Shown are the initial positions of the above-mentioned respective parts, Figure 2 and Figure 3 shown are the positions of the above-mentioned parts after movement; initially, the telescopic end of the spring telescopic rod 29 is in a contracted state, and at this time the spring telescopic rod 29 is not storing energy; both the interior of the third liquid storage shell 30 and the hose thereon store hydraulic oil, and initially the lower end of the third piston rod 31 is located above the adjacent mounting shell 6.

[0086] The following takes the movement process of the main welding wire as an example for description:

[0087] Before the above-mentioned staff fixes the main welding wire, the staff first rotates the second fixing block 27 counterclockwise. The second fixing block 27 drives the second extrusion block 28 to rotate synchronously through the spring telescopic rod 29, and twists and stores energy in the torsion spring on the second fixing block 27. 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, synchronously pulls out the telescopic end of the spring telescopic rod 29 and makes the spring telescopic rod 29 store energy. Subsequently, the staff fixes the main welding wire according to the above operation. During the upward movement of the above-mentioned second moving rod 23, the hydraulic oil in the second liquid storage shell 25 moves into the liquid storage pipe 22 through the soft pipe, and makes the third piston rod 31 move 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 inside the mounting shell 6, and the lower end of the third piston rod 31 is located in front of the second extrusion block 28, limiting the second extrusion block 28, and further limiting the second fixing block 27 and the spring telescopic rod 29.

[0088] After the above-mentioned main welding wire breaks, the hydraulic oil in the liquid storage pipe 22 moves into the second liquid storage shell 25 and also moves into the third liquid storage shell 30 through the hose, making the third piston rod 31 move upward under 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 no longer contacts the second extrusion block 28, so that the second fixing block 27 drives the second extrusion block 28 to rotate synchronously clockwise through the spring telescopic rod 29 under the action of the torsion spring thereon until the torsion spring on the second fixing block 27 returns to the non-energy storage state, and the second fixing block 27 rotates clockwise by 90°.

[0089] During the clockwise rotation of the above-mentioned second fixed block 27, the telescopic end of the spring telescopic rod 29 drives the second extruding 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 extruding block 28 and the second fixed block 27, and the second extruding 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 extruding 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.

[0090] After the main welding wire is broken, the staff will shut down the device, connect the main welding wire, reset the parts to their initial positions, and then continue to prepare the required cable welding wire according to the above operations.

[0091] Further, such as Figure 2 and Figure 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.

[0092] The following description is made by taking the moving process of the middle limit rod 32 as an example:

[0093] 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.

[0094] During the process of the above-mentioned second fixed block 27 driving the adjacent second extrusion block 28 to rotate clockwise, when the second extrusion block 28 contacts the limit rod 32, the second extrusion block 28 squeezes the inclined surface of the limit rod 32, causing the limit rod 32 to move upward and stretching the tension spring on the limit rod 32 to store energy. Until the second extrusion block 28 completely loses contact with the limit rod 32, the limit rod 32 moves downward to the initial position under the action of its sixth tension spring. At this time, the limit rod 32 limits the second extrusion block 28, making the second extrusion block 28 unable to reset, thereby increasing the fixing force of the second extrusion block 28 and the second fixed block 27 on the main welding wire, avoiding the situation that the main welding wire drives the second extrusion block 28 and the second fixed block 27 to shake during the relaxation process, resulting in the separation of the second extrusion block 28 and the second fixed block 27 from the main welding wire. Subsequently, the staff shuts down the device, and the staff rotates the second extrusion block 28 and the second fixed block 27 counterclockwise again (the specific process can refer to the movement process of the second extrusion block 28 and the second fixed block 27 during the above-mentioned welding wire fixing process). Subsequently, the broken welding wire is reconnected to continue using the device to prepare the cable-type welding wire.

[0095] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
