Description

Technical Field

[0001] This invention relates to the field of steel wire welding technology, and more specifically, to a butt welding device that enables continuous wire feeding. Background Technology

[0002] Steel wire processing belongs to metal plastic processing. Its process is mainly divided into four core links: raw material processing, drawing and forming, heat treatment, and surface treatment. If steel wire rope is to be produced, a twisting process is also required. After drawing and forming, the steel wire can be directly guided into the heat treatment process. Since drawing and forming and heat treatment are two independent processes, if there is a time difference in the process, then the coil needs to be cut according to the actual length and stored.

[0003] During heat treatment, the steel wire stored on the coil needs to be unwound through a rotatable winding seat and a winding frame. Then, a guiding mechanism guides the steel wire into the heat treatment area for heat treatment. During the heat treatment process, the guiding mechanism needs to continuously guide the steel wire. However, since the steel wire coil is an independent part, when the first steel wire coil is finished being guided, the beginning of the steel wire coil on another winding seat needs to be connected to the end of the steel wire coil that is about to finish unwinding using welding equipment. During this process, the heat treatment device needs to be started and stopped intermittently, which makes the process cumbersome and has a certain impact on the overall progress of the steel wire heat treatment.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a butt welding device that can realize continuous wire feeding. Summary of the Invention

[0009] Preferably, the transmission mechanism a includes a transmission box; The transmission box is equipped with a drive seat on top, and a spherical slider is provided on the side of the drive seat to limit the movement of the transmission mechanism a during its circular motion. The bottom of the transmission box is connected to a guide seat, and an outlet end is provided on the side wall of the transmission box; The transmission mechanism a further includes a guide component disposed within the transmission mechanism a and a motor c that drives the guide component; The guiding assembly includes two transmission rollers that rotate relative to each other through gear meshing, and a guide wheel b, one of the two transmission rollers, which is driven by a transmission belt. One of the two transmission rollers is connected to the transmission end of a motor c through a coupling. A torque sensor is installed on the guide wheel b.

[0010] Preferably, the rotating guide includes a rotating base and a guide plate; The bottom of the guide seat is provided with a guide end, the rotating seat is nested and rotatably connected to the guide seat, and the rotating seat is connected to the guide plate through a curved connecting rod; The guide plate, guide end, and lead-out end are equipped with ball bearings arranged in a circumferential pattern to assist in the transmission of steel wire.

[0011] Preferably, the transmission mechanism b includes a gear plate and a carrier plate that are limited to rotating on the bottom surface of the top plate and connected to the transmission end of the motor b via a coupling. The top of the carrier plate is provided with a connecting column that connects to the bottom surface of the top plate. The bottom of the carrier plate is provided with two guide wheels c for limiting the transmission of steel wire and guide wheels d for secondary guidance of the steel wire transmitted by the two guide wheels c. Both guide wheels c and guide wheels d are provided with torque sensors.

[0012] Preferably, a rotating sleeve with teeth is nested on the connecting column and can mesh with the gear plate. The rotating sleeve is respectively limited to rotating connection with the carrier plate and the connecting column. A support rod connected to the drive seat is provided in the area below the teeth.

[0013] Preferably, the control box is equipped with an equipment control system, which includes an execution control module, a data acquisition module, and an analysis and judgment module; Among them, the data acquisition module collects the tension data of the steel wire at each transmission node during the steel wire laying and guiding process; The analysis and judgment module analyzes and calculates the rotational speeds of motors a and c by collecting tension data; The execution control module adaptively controls motor a, motor b, motor c, cylinder a, and cylinder b according to the execution instructions.

[0014] A butt welding method for continuous wire feeding, the specific steps of which are as follows: S1. By flipping the two wire placement seats, wire spools are placed on the winding frame. At the same time, the wire spools are adjusted. The lengths of the ends of the wire spools for pre-leading wire and the beginning and end of the wire spools for not leading wire need to be adjusted to ensure that the end of the wire spools for pre-leading wire and the beginning of the wire spools for not leading wire are within the welding port of the welding area and make contact. After the wires on the wire spools for pre-leading wire are led for the first time, the operation can begin. S2. Start motors a and c. The steel wire on the steel wire placement seat corresponding to the transmission mechanism a is spirally laid out through the guide plate, and then guided through the transmission mechanism a, transmission mechanism b and guide wheel a in sequence. During the steel wire guidance process, the torque sensor monitors and adjusts the speed of motors a and c accordingly. When the steel wire is spirally fed through the guide plate, the guide plate will drive the rotating seat to rotate adaptively according to the torque generated by the spiral of the steel wire, thus buffering the torque generated by the spiral feeding. S3. During the wire feeding process in S, the beginning and end of the wire spool in S are welded together. When the wire on the pre-fed wire spool ends, and the guide plate is outside the wire placement seat, and the wire can be completely separated from the wire placement seat by the rotation of the transmission mechanism a, the motor b is started. S4. Driven by motor b, the transmission mechanism a rotates along the trajectory of the arc groove. During the rotation of the transmission mechanism a, the wire feeding guidance will continue, and the position of the wire on the guide wheel c will also change, moving from the original guide wheel c to another guide wheel c. During this process, the tension will change accordingly. The speed of motor a and motor c will be adjusted accordingly by monitoring the torque sensor. When the transmission mechanism a rotates to the top side of another pre-feeding wire placement seat, the wire feeding end will also be introduced to the pre-feeding wire placement seat through the gapless guidance between the welded wires, thereby realizing the switching of wire feeding guidance between the two wire placement seats. When the transmission mechanism a rotates to the top side of another pre-laid wire placement seat, a certain length of wire needs to be reserved between the first end of the wire spool on the wire placement seat and the guide plate to guide the wire transmission. S5. For the wire placement seat where the wire feeding has ended, flip it over and place a new wire spool, leaving the lengths at the beginning and end. Weld the beginning of the wire spool to the end of the wire feeding spool. Repeat step S4 before the wire feeding guidance ends.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This welding device effectively combines the wire placement seat with the welding equipment. Utilizing the characteristics of longitudinal spiral wire feeding, the end of the wire spool can be kept stationary during the feeding process. The stationary end of the wire spool can be welded to the beginning of the wire spool on another wire placement seat without affecting the wire feeding guidance, thus achieving synchronization between wire feeding and welding.

[0016] 2. This welding device utilizes the symmetry of the wire placement seat. By rotating the wire guide part in a circular motion and coordinating with the spiral wire feeding trend of the wire reel, the position of the wire feeding can be shifted without affecting the wire feeding guidance. This allows for continuous wire feeding guidance while seamlessly switching between the wire reels on the two wire placement seats.

[0017] 3. This welding device uses a pre-welding mode during the wire reel feeding process, combined with the switching between two wire placement seats, to make the replacement of the wire reel between the two wire placement seats cyclical throughout the entire wire guiding process. This effectively integrates the continuous wire guiding with the welding process and the wire reel replacement process, improving the wire processing efficiency and avoiding the problem of cumbersome processes affecting the processing progress.

[0020] like Figure 1-15 As shown, the present invention provides a butt welding device that enables continuous wire feeding, including a welding seat 1, a wire placement seat 2 located on both sides of the welding seat 1 and capable of being flipped, and a top plate 3 connected by a column and covering the top area of ​​the welding seat 1 and the wire placement seat 2. The wire placement seat 2 includes a placement plate 201 with a winding frame and a support seat 202 rotatably connected to the placement plate 201. The support seat 202 is equipped with a cylinder a203 that controls the flipping of the placement plate 201 by telescopic movement. The wire placement seat 2 is specifically divided into two parts: the placement plate 201 and the support seat 202. The placement plate 201 is set on an adjusting seat on the top of the support seat 202. The adjusting seat and the support seat 202 are rotatably connected. The adjusting seat is rotated and adjusted by telescopic movement of the bottom cylinder a203. The placement plate 201 is equipped with a winding frame. The adjusting seat drives the placement plate 201 to tilt, thereby providing convenience for the installation of the wire reel. The winding frame is composed of multiple independent rods. The frame is cylindrical in shape. The radius of the winding frame needs to be smaller than the radius of the wire reel. The diameter of the wire reel needs to be adjusted specifically in conjunction with the adaptive rotation of the rotating seat 9.

[0021] like Figure 4 As shown, the device also includes a transmission mechanism b6 located on the top plate 3 and a transmission mechanism a5 connected to the transmission mechanism b6 and driven by a motor b301 on the top plate 3 to perform circular motion. An arc-shaped groove 302 is provided on the bottom surface of the top plate 3. like Figure 7 and Figure 8 As shown, the transmission mechanism a5 includes a transmission box 501; Among them, the top of the transmission box 501 is provided with a drive seat 502, and a spherical slider 503 is provided on the side of the drive seat 502 to limit the transmission mechanism a5 when the transmission mechanism a5 moves in a circular motion. Furthermore, in combination Figure 6 As shown, in order to improve the smoothness of the circular motion of the transmission mechanism a5, the spherical slider 503 and the arc groove 302 are in a limiting fit connection form. When the spherical slider 503 runs along the arc trajectory of the arc groove 302, it will not get stuck due to factors such as sharp corners. During the sliding process, lubricant or lubricating oil can be added to the arc groove 302 to reduce friction and enhance the smoothness of sliding. like Figure 9 and Figure 10As shown, a guide seat 8 is connected to the bottom of the transmission box 501, and an outlet end 507 is provided on the side wall of the transmission box 501. Meanwhile, in order to achieve transmission control of the first section of the steel wire, such as Figure 8 As shown, the transmission mechanism a5 also includes a guide component disposed within the transmission mechanism a5 and a motor c506 for driving the guide component; The guiding assembly includes two transmission rollers 505 that rotate relative to each other through gear meshing, and one of the two transmission rollers 505 is driven by a transmission belt, and one of the two transmission rollers 505 is connected to the transmission end of the motor c506 through a coupling. A torque sensor is provided on the guide wheel b504. Specifically, the guiding component is a synchronous transmission mechanism consisting of rollers and wheels, driven by motor C506. During the wire transmission process, the tension generated by the wire in the first stage of transmission can be monitored by the torque sensor on the guide wheel B504, thereby further adjusting the speed of motor C506 to achieve the optimal state of wire transmission.

[0022] The transmission mechanism a5 is equipped with a rotating guide that can be adapted to perform longitudinal spiral feeding of the steel wire on the steel wire placement seat 2. The rotating guide, in conjunction with the movement of the transmission mechanism a5, can cause the pre-fed steel wire to detach from the steel wire placement seat 2. The rotating guide is used to buffer the torque generated during the spiral unwinding process and the transmission of the steel wire. Figure 12 As shown, the rotating guide includes a rotating base 9 and a guide plate 10; The bottom of the guide seat 8 is provided with a guide end 801, and the rotating seat 9 is nested and rotatably connected to the guide seat 8. The rotating seat 9 is connected to the guide disk 10 through a curved connecting rod. The rotating structure can adopt a bearing structure. To further explain, the curved connecting rod can be S-shaped. The curved connecting rod can position the guide plate 10 on the outside of the winding frame. The specific position needs to be matched according to the diameter of the wire spool. The spiral wire will form a spiral motion tendency. The adaptable rotating seat 9 drives the guide plate 10 to move according to the position of the spiral wire, thereby reducing the torque generated by the wire during the spiral wire feeding process to a certain extent and ensuring normal wire transmission. At the same time, when the wire spool is about to finish feeding, for example, when it is at the end of the last turn (1 / 4, 1 / 5 or 1 / 6), when the transmission mechanism a5 rotates and drives the wire to switch to the wire placement seat 2, the guide plate 10 can guide the wire. The guide plate 10 can also be connected to the winding frame through a rotating shaft. To avoid scratches during the transmission of the steel wire, such as Figure 9 , Figure 11 and Figure 12 As shown, the guide plate 10, the guide end 801 and the lead-out end 507 are provided with balls 7 arranged in a circumferential pattern to assist in the transmission of steel wire. Specifically, the guide plate 10, the guide end 801, and the lead-out end 507 are all guide parts of the steel wire. During the wire's transmission, it will pass through the gaps between the circularly distributed balls 7. For example, when the tension is insufficient during the wire transmission process or during the guide position adjustment process, the steel wire will come into contact with the balls 7 and make a smooth transition through the balls 7 to avoid hard friction.

[0023] In order to control the overall circular motion of the transmission mechanism a5 without affecting the normal transmission of the steel wire, such as Figure 4 , Figure 7 and Figure 13 As shown, the transmission mechanism b6 includes a gear disk 601 that is limited to rotating on the bottom surface of the top plate 3 and connected to the transmission end of the motor b301 through a coupling and a carrier plate 602. The gear disk 601 is the main driving component and is directly driven by the motor b301. The carrier plate 602 is the mounting part of the steel wire mid-section transmission guide assembly. like Figure 7 , Figure 13 and Figure 14 As shown, the top of the carrier plate 602 is provided with a connecting column 604 that is connected to the bottom surface of the top plate 3. The bottom of the carrier plate 602 is provided with two guide wheels c605 that limit the transmission of steel wire and a guide wheel d606 that provides secondary guidance for the steel wire transmitted by the two guide wheels c605. A torque sensor is provided on both the guide wheel c605 and the guide wheel d606. Furthermore, there are two guide wheels c605, each corresponding to a guide position on one of the two wire placement seats 2. The wire is transmitted between the two guide wheels c605. When the wire is guided through one of the wire placement seats 2, it will be guided by its corresponding guide wheel c605. When the transmission mechanism a5 performs circular motion, the wire will transition from one guide wheel c605 to the other. Since the guide position of the wire changes, the tension of the wire during transmission will also change. The torque sensors on guide wheels c605 and d606 monitor the changes, and in conjunction with the torque sensors on guide wheels a101 and b504, the speeds of motors c506 and a102 are adaptively adjusted to balance the tension, thereby improving the overall stability of the wire transmission. It needs to be explained that, Figure 9 , Figure 15As shown, when the steel wire passes through guide wheel c605, it needs to be in contact with both guide wheels c605 simultaneously, that is, the two guide wheels c605 are in a clamping state for the steel wire. This state is actually to ensure that when the steel wire, the two guide wheels c605, and guide wheel d606 are collinear, the two guide wheels c605 also have a guiding effect on the steel wire. Specifically, this effect includes ensuring stable transmission of the steel wire by the two guide wheels c605 when collinear, and also ensuring the accuracy of the data monitored by the torque sensor on the guide wheel c605.

[0024] To drive the circular motion of the transmission mechanism a5, such as Figure 7 As shown, a rotating sleeve 603 with teeth is nested on the connecting column 604 and can mesh with the gear plate 601. The rotating sleeve 603 is respectively limited to the rotational connection of the carrier plate 602 and the connecting column 604. A support rod connected to the drive seat 502 is provided in the area below the teeth. Furthermore, the rotating sleeve 603 adopts an upper drive and lower connection form. The teeth of the rotating sleeve 603 located on the top edge mesh with the gear disk 601, and the gear disk 601 drives the rotating sleeve 603 to rotate as a whole. At the same time, the bottom part of the rotating sleeve 603 is connected to the drive seat 502 by a support rod. Through the setting of the staggered distribution structure, the synchronization of driving and linkage is realized. Meanwhile, in order to ensure that the transmission mechanism a5 can rotate symmetrically, the distance between the spherical slider 503 and the rotating sleeve 603 must be greater than the diameter of the gear plate 601.

[0025] like Figure 5 As shown, the welding seat 1 of this device is provided with a guide wheel a101 that can be driven by a motor a102 on the side, and a welding area 4 that allows the end of the wire on one of the two wire placement seats 2 to be welded to the beginning of the wire on the other wire placement seat 2 when the wire is laid out. To ensure the stability of the welding, a welding port is provided on the welding area 4. A clamping plate 403 is provided inside the welding port to clamp the steel wire. A cylinder b402 and a control box 401 are provided on the top of the welding port to control the clamping of the clamping plate 403. A torque sensor is provided on the guide wheel a101. Specifically, the first and last ends of the two steel wires are placed on the wire reel on the seat 2, with the ends inside the welding port. The cylinder b402 is used to press the first and last steel wire sections together. The specific welding method can be achieved by installing a welding head at the welding port. The type of welding head can be adapted according to the actual situation. Alternatively, a welding head can be omitted, and welding can be performed manually using welding tools. If a welding head is installed, it can be connected to the control box 401 for execution control. The guide wheel a101 can guide the steel wire to the subsequent processing area. The torque sensor on the guide wheel a101 can also monitor the tension change of the guide wheel a101 during the process of guiding the steel wire.

[0026] Meanwhile, the control box 401 is equipped with an equipment control system for overall control of the device. The equipment control system includes an execution control module, a data acquisition module, and an analysis and judgment module. The data acquisition module collects the tension data of the steel wire at each transmission node during the wire laying process; The analysis and judgment module analyzes and calculates the rotational speeds of motors A102 and C506 by collecting tension data. The execution control module adaptively controls motors a102, b301, c506, a203, and b402 according to the execution instructions.

[0027] The specific steps for wire laying and welding using this device are as follows: S1. Two wire placement seats 2 are flipped to place wire spools on the winding frame. At the same time, the wire spools are adjusted. The lengths of the ends of the wire spools with pre-leaded wire and the beginning and end of the wire spools without lead wire need to be adjusted manually to ensure that the ends of the wire spools with pre-leaded wire and the beginning of the wire spools without lead wire are within the welding port of the welding area 4 and are in contact. After the wires on the wire spools with pre-leaded wire are led for the first time, the operation can begin. The initial wire feeding requires manual intervention, with the control box 401 controlling motors a102 and c506 to sequentially introduce the first end of the pre-laid wire reel into the transmission mechanism a5 and transmission mechanism b6, then guide it out by the guide wheel a101 and connect it to the guide part of the subsequent processing equipment. S2. Start the guide wheel a101 and motor c506. The steel wire on the steel wire placement seat 2 corresponding to the transmission mechanism a5 is spirally released through the guide plate 10, and then sequentially passes through the transmission mechanism a5, transmission mechanism b6, guide wheel c605, guide wheel d606 and guide wheel a101 for path guidance. During the steel wire guidance process, the torque sensor monitors and adaptively adjusts the speed of motor a102 and motor c506. When the steel wire is spirally unloaded through the guide plate 10, the rotating seat 9 will be driven by the guide plate 10 to rotate adaptively according to the torque generated by the spiral of the steel wire, thereby buffering the torque generated by the spiral unloading and greatly reducing the impact on the transmission and guidance of the steel wire. S3. During the wire feeding process in S2, the beginning and end of the wire reel in S1 are welded together. Before the wire feeding on the wire reel is finished, it must be ensured that the guide plate 10 is outside the wire placement seat 2. When the wire can be completely separated from the wire placement seat 2 through the rotation of the transmission mechanism a5, the motor b301 is started. Among them, the determination of the end of wire feeding on the wire feeding spool can be made manually or by the system adaptively based on the wire's conduction. For adaptive determination, for example, if the default speed of motor c506 is set to V1 and the total length of the wire reel is L1, it can be determined that when the guide plate 10 is outside the wire placement seat 2, the number of revolutions of motor c506 when the wire can be completely separated from the wire placement seat 2 through the rotation of the transmission mechanism a5 is denoted as N, and the time required is T. Through multiple sets of experiments, the effect of the tension adjustment timing on the speed of motor c506 during the process from the beginning to the end of the wire reel is determined, i.e., the instantaneous speed V2. Thus, the time T1, T2, etc. of multiple wire reels from the beginning to the end under N revolutions are obtained. According to the allowable position of guide plate 10, i.e. the separation position, all the times when guide plate 10 is in the allowable separation position are selected, and the average value T3 is taken. Then, the default speed of motor c506 is V3. The average speed deviation caused by the tension change is calculated, and the initial average speed is corrected to obtain the final default speed V4. The time T3 of motor c506 is used as the determination point. When making a human judgment, real-time observation is required. At the same time, the guide plate 10 is located on one side of the wire placement seat 2. This position is not a specific position, but any position within the allowable separation range. Therefore, the timing of separation needs to be precisely controlled. Within the timing, the motor b301 can be manually started. S4. Driven by motor b301, the transmission mechanism a5 rotates along the trajectory of the arc groove 302. During the rotation of the transmission mechanism a5, the wire feeding guidance will continue, and the position of the wire on the guide wheel c605 will also change, moving from the original guide wheel c605 to another guide wheel c605. During this process, the tension will change accordingly. This is monitored by the torque sensor, and the speed of motor a102 and motor c506 is adjusted to adapt. When the transmission mechanism a5 rotates to the top side of another pre-feeding wire placement seat 2, the wire feeding is also introduced to the pre-feeding wire placement seat 2 through the seamless transmission between the welded wires, thereby realizing the switching of wire feeding guidance between the two wire placement seats 2. When the transmission mechanism a5 rotates to the top side of another pre-laid wire placement seat 2, a certain length of wire needs to be reserved between the first end of the wire spool on the wire placement seat 2 and the guide plate 10 to guide the wire transmission. Furthermore, to ensure the stability of wire transmission, the speed of motor b301 must be less than the speed V4 of motor c506. At the same time, the length of the two wire placement seats 2 after welding needs to be sufficiently redundant. While ensuring the stability of wire transmission during the rotation of transmission mechanism a5, it is also necessary to reach the top side of the other pre-laid wire placement seat 2 at the set speed of motor b301 before the wire redundancy ends, so as to achieve a smooth transition of transmission. The speed of motor b301 can be adaptively adjusted according to the distance of arc groove 302 and the speed V4 of motor c506, as well as the redundant length of wire welding and the speed of motor a102. S5. For the wire placement seat 2 where the wire feeding has ended, flip it over and place a new wire spool, reserving the length of the beginning and end, and weld the beginning of the wire spool to the end of the wire feeding spool. Repeat step S4 before the wire feeding guidance ends.

9. A butt welding method for continuous wire feeding, applied to the butt welding device for continuous wire feeding as described in any one of claims 1 to 8, characterized in that: The specific steps are as follows: S1. Two wire placement seats (2) are flipped to place wire spools on the winding frame. At the same time, the wire spools are adjusted. The lengths of the end of the wire spool for pre-leading wire and the beginning and end of the wire spool for not leading wire need to be manually adjusted and adapted so that the end of the wire spool for pre-leading wire and the beginning of the wire spool for not leading wire can be in the welding port of the welding area (4) and in contact. After the first wire is led on the wire spool for pre-leading wire, the operation can begin. S2. Start motor a (102) and motor c (506). The wire on the wire placement seat (2) corresponding to the transmission mechanism a (5) is spirally laid out through the guide plate (10), and then guided through the transmission mechanism a (5), transmission mechanism b (6) and guide wheel a (101) in sequence. During the wire guidance process, the torque sensor monitors and adjusts the speed of motor a (102) and motor c (506) accordingly. When the steel wire is spirally unloaded through the guide plate (10), the guide plate (10) will drive the rotating seat (9) to rotate adaptively according to the torque generated by the spiral of the steel wire, thereby buffering the torque generated by the spiral unloading. S3. During the wire feeding process in S2, the beginning and end of the wire reel in S1 are welded together. Before the wire feeding on the wire reel is finished, it must be ensured that the guide plate (10) is outside the wire placement seat (2). When the wire can be completely separated from the wire placement seat (2) by the rotation of the transmission mechanism a (5), the motor b (301) is started. S4. Driven by motor b (301), the transmission mechanism a (5) rotates along the trajectory of the arc groove (302). During the rotation of the transmission mechanism a (5), the wire feeding guidance will continue, and the position of the wire on the guide wheel c (605) will also change, moving from the original guide wheel c (605) to another guide wheel c (605). During this process, the tension will change accordingly. By monitoring the torque sensor, the speed of motor a (102) and motor c (506) will be adjusted accordingly. When the transmission mechanism a (5) rotates to the top side of another pre-feeding wire placement seat (2), the wire feeding end will also be introduced to the pre-feeding wire placement seat (2) through the gapless guidance between the welded wires, thereby realizing the switching of wire feeding guidance between the two wire placement seats (2). When the transmission mechanism a (5) rotates to the top side of another wire placement seat (2) for pre-laying wire, a certain length of wire needs to be reserved between the first end of the wire spool on the wire placement seat (2) and the guide plate (10) to guide the wire transmission. S5. For the wire placement seat (2) where the wire laying has ended, flip it over and place a new wire spool, leaving the length of the beginning and end, and weld the beginning of the wire spool to the end of the wire spool where the wire laying is completed. Repeat step S4 before the wire laying guidance ends.
