Description

Technical Field

[0001] The invention belongs to the technical field of alloy welding wires, and in particular relates to a high-quality preparation device for alloy welding wires. Background Art

[0002] Alloy welding wire is an alloy product used as filler metal or conductive material in the welding process. It is widely used in high-end manufacturing industries such as aerospace, automobile manufacturing, shipbuilding, pressure vessels, and electronic devices. Since these application fields have extremely high requirements for welding quality and reliability, the quality of alloy welding wire directly affects key performance indicators such as strength, corrosion resistance, and conductivity of the welded joint. Therefore, the preparation of high-quality alloy welding wire is a key link to ensure welding quality and product reliability. The appropriate alloy material is selected and proportioned according to the formula. The prepared alloy material is melted and cast into alloy ingots. The alloy ingots are hot-rolled and cold-rolled to form alloy wires of a certain size. The alloy wires are heat-treated to adjust their mechanical properties and internal structure. The alloy wires are surface-treated, such as cleaning, polishing, and plating, to improve their corrosion resistance and welding performance. The treated alloy wires are wound and packaged.

[0003] The existing high-quality preparation devices for alloy welding wires mainly have the following deficiencies:

[0004] The existing high-quality preparation equipment for alloy welding wires has poor adaptability to welding wires of different diameters or lengths, and cannot flexibly adjust the clamping height. If the specifications of the welding wire change, the entire set of clamping components may need to be replaced, which is complicated to operate and reduces production efficiency. In addition, there is a lack of effective welding wire guide design, and the welding wire is prone to deviation during transportation and processing, affecting the quality and accuracy of the final product. It is difficult to quickly adapt to the preparation needs of different specifications and different types of alloy welding wires. Each welding wire may have different diameters and material properties. When some existing preparation devices adjust equipment parameters and replace tooling fixtures to meet the production of different welding wires, the operation is complicated and time-consuming, which reduces production efficiency and lacks flexibility to meet diversified production needs.

DETAILED DESCRIPTION

[0031] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0032] like Figures 1-8 As shown, the present invention provides a technical solution:

[0033] A high-quality preparation device for alloy welding wire, comprising:

[0034] The base 1 is provided with a moving structure 2 at the center of the upper end surface of the base 1. The moving structure 2 includes a first slide 201, the first slide 201 is provided at the center of the upper end surface of the base 1, a connecting block 202 is provided at the center inside the first slide 201, and a first servo motor 206 is provided at the center of one side wall of the base 1. The output end of the first servo motor 206 passes through one side wall of the base 1 and one side wall of the first slide 201 to the inside of the first slide 201, and the end is fixedly connected to the first screw rod 203. The output end of the first screw rod 203 passes through one side wall of the connecting block 202 to the other side wall, and the end is fixedly connected to the second screw rod 204. The outer wall of the first screw rod 203 and the outer wall of the second screw rod 204 are both threaded with a first slider 205. The first screw rod 203 and the second screw rod 2 04 are set with opposite threads, and the first servo motor 206 is started to drive the first screw rod 203 to rotate. Since the thread directions of the first screw rod 203 and the second screw rod 204 are opposite, and the two are coaxially fixed by the connecting block 202, when the first screw rod 203 rotates, it will drive the second screw rod 204 to rotate synchronously in the opposite direction. The first slider 205 on the outside of the first screw rod 203 and the second screw rod 204 have opposite thread directions and will move in opposite directions during rotation to achieve lateral displacement along the first slide groove 201. The movement of the two first sliders 205 can drive the upper positioning structure 5 to move synchronously. Through the precise control of the first servo motor 206, the lateral position adjustment of the positioning structure 5 on the base 1 is achieved, providing a precise positioning reference for subsequent welding wire processing.

[0035] An operating table 3 is provided at the center of the upper end surface of the connecting block 202, and a connecting structure 4 is provided at the center of the upper end surface of the operating table 3. The connecting structure 4 includes a mounting groove 401, which is provided at the center of the upper end surface of the operating table 3. A card slot 406 is provided on the upper end surface of the operating table 3 on both sides of the front end surface of the mounting groove 401 and on both sides of the rear end surface. A protective frame 402 is provided on the inner wall of the mounting groove 401. A card block 405 is provided on both sides of the center of the front end surface of the protective frame 402 and on both sides of the center of the rear end surface. A placement frame 403 is provided on the inner wall of the protective frame 402. A wire groove 404 is provided at the center of the wall. The protective frame 402 is engaged with the card slot 406 on the operating table 3 through the front and rear end blocks 405 and is fixed in the installation groove 401, forming preliminary protection for the internal placement rack 403. The placement rack 403 is nested on the inner side of the protective frame 402. The wire grooves 404 on both sides are used to store cables or wires during the welding wire processing process to avoid line entanglement affecting operation. The cooperation of the card block 405 and the card slot 406 realizes the quick assembly and disassembly of the protective frame 402 and the placement rack 403, which is convenient for replacing or maintaining internal components and improving equipment maintenance efficiency.

[0036] A positioning structure 5 is provided at the center of the upper end surface of the two first sliders 205. The two positioning structures 5 include two positioning frames 501. The two positioning frames 501 are respectively arranged at the center of the upper end surface of the two first sliders 205. A protective cover 515 is provided at the center of the front end surface of the two positioning frames 501. Three mounting columns 517 are arranged in a triangular pattern at the lower center of the two positioning frames 501. An adjusting rod 511 is provided at the center of the upper end surface of the two positioning frames 501. One end of the two adjusting rods 511 passes through the upper end surface of the two positioning frames 501 and passes into the interior of the two positioning frames 501. The ends are fixedly connected to a lifting block 512. The center of the front end surface of the mounting column 517 is threadedly connected with a locking block 510, and the center of the upper front end surface of the six mounting columns 517 is provided with a sliding groove 505. The outer walls of the two mounting columns 517 on one side are sleeved with a first gear 506, and the outer walls of the two mounting columns 517 at the center are sleeved with a second gear 508. The outer walls of the two mounting columns 517 on the other side are sleeved with a third gear 509. The two first gears 506, the two second gears 508 and the two third gears 509 are each provided with a sliding block 507 at the center of the front end surface, and the six sliding blocks 507 are respectively slidably connected to the inner center of the six sliding grooves 505.

[0037] The two first gears 506 are respectively meshed with the two second gears 508 and the two third gears 509. A first through-hole 502 is provided at the upper center of one side wall of the two positioning frames 501. First positioning wheels 503 are provided at the upper sides of the rear inner walls of the two positioning frames 501. Second positioning wheels 504 are provided inside the two positioning frames 501 on the lower end faces of the two first positioning wheels 503. A second through-hole 513 is provided at the center of the lower end faces of the two lifting blocks 512. A third through-hole 514 is provided at the center of the other side wall of the two positioning frames 501. A second servo motor 516 is provided at the lower center of the rear end faces of the two positioning frames 501. The two second servo motors 516 respectively pass through the rear end faces of the two positioning frames 501 and the rear end faces of the two mounting columns 517 at the center and pass into the interior of the two mounting columns 517 at the center.

[0038] By starting the second servo motor 516 to drive the mounting post 517 at the center to rotate, the center mounting post 517 is rotated to drive the second gear 508 at the center to rotate, and the second gear 508 drives the first gear 506 and the third gear 509 to engage and transmit, and the locking block 510 is connected to the mounting post 517 through a thread. When the first gear 506, the second gear 508 and the third gear 509 rotate, the locking block 510 limits the first gear 506, the second gear 508 and the third gear 509 to prevent them from rotating out of the device, and the locking block 510 is locked. The first gear 506, the second gear 508 and the third gear 509 are fixed on the mounting column 517 for rotation. The adjusting rod 511 passes through the upper end surface of the positioning frame 501 and is fixed to the lifting block 512. Rotating the adjusting rod 511 can drive the lifting block 512 to move up and down, thereby adjusting the height of the third through-hole 514 to adapt to the clamping requirements of welding wires of different diameters or lengths. The first positioning wheel 503 and the second positioning wheel 504 are arranged inside the positioning frame 501 to guide the direction of the welding wire and ensure that the welding wire maintains linear motion during clamping and processing to avoid offset affecting the processing accuracy.

[0039] A cutting structure 6 is provided at the front center of both side walls of the operating table 3. The two cutting structures 6 include two frames 601. The two frames 601 are respectively provided at the front center of both side walls of the operating table 3. A second slide 602 is provided at the center of the rear end surface of the two frames 601. A third servo motor 603 is provided at the rear center of the upper end surface of the two frames 601. The output ends of the two third servo motors 603 respectively pass through the upper end surfaces of the two frames 601 and the upper end surfaces of the two second slides 602 to the inside of the two second slides 602, and the ends are fixed. A third screw rod 604 is fixedly connected, and the outer side walls of the two third screw rods 604 are threadedly sleeved with a second slider 605. A cutter 606 is provided at the center of the upper end surface of the two second sliders 605. By starting the third servo motor 603 to drive the third screw rod 604 to rotate, the second slider 605 threadedly sleeved on the third screw rod 604 moves up and down along the second slide groove 602, driving the cutter 606 to achieve precise lifting and lowering in the vertical direction. The cutter 606 cuts the welding wire by the downward movement of the second slider 605 to meet the size requirements of high-quality welding wire.

[0040] Three auxiliary structures 7 are arranged horizontally at the center of the upper end surface of the operating table 3. The three auxiliary structures 7 include three auxiliary frames 701. The three auxiliary frames 701 are respectively arranged horizontally on the upper end surface of the operating table 3 at the upper end of the connecting structure 4. Electric telescopic rods 702 are provided at the front and rear centers of the inner walls of the three auxiliary frames 701. The six electric telescopic rods 702 are grouped into two. Rubber plates 703 are provided at the centers of the lower ends of the three groups of electric telescopic rods 702. During the preparation processes such as alloy welding wire cutting, welding and grinding, the electric telescopic rod 702 is started. The extension of the electric telescopic rod 702 will drive the lower end rubber plate 703 to move downward, tightly pressing the alloy welding wire placed below. Because the rubber plate 703 is soft and elastic, it can stabilize the alloy welding wire by relying on large friction without damaging the surface of the alloy welding wire, preventing the welding wire from sliding and shifting due to the cutting force during the cutting process, thereby ensuring processing accuracy. After the process is completed, the electric telescopic rod 702 is shortened and the rubber plate 703 is raised to release the pressure on the alloy welding wire, making it convenient to replace the alloy welding wire or carry out the next operation.

[0041] The working principle of the present invention is as follows: by embedding the protective frame 402 into the card slot 406 of the operating table 3 through the front and rear end blocks 405, fixing it in the installation slot 401, and then nesting the placement frame 403 into the inner side of the protective frame 402, ensuring that the wire grooves 404 on both sides are aligned, which are used to organize the conductive cables or control lines in subsequent processing, by spreading the alloy welding wire raw material flat on the placement frame 403, and extending the two ends into the positioning frames 501 of the positioning structures 5 on both sides respectively, by adjusting the adjustment rod 511 on the positioning frame 501, driving the lifting block 512 to move up and down, so that the height of the mounting column 517 matches the diameter of the welding wire, and by starting the first servo motor 206 to drive the first screw rod 203 and the second screw rod 204 to rotate. Since the thread directions of the two are opposite, the first sliders 205 on both sides will move synchronously in opposite directions, driving the positioning frame 501 to move horizontally, so that the welding wire is in the center position of the operating table 3, ensuring the subsequent cutting accuracy.

[0042] By starting the second servo motor 516 at the rear end of the positioning frame 501, the central mounting column 517 is driven to drive the second gear 508 to rotate, and the second gear 508 drives the first gear 506 and the third gear 509 to engage and transmit. The locking block 510 is connected to the mounting column 517 by a thread. When the first gear 506, the second gear 508 and the third gear 509 rotate, the locking block 510 limits the first gear 506, the second gear 508 and the third gear 509 to prevent them from rotating out of the device. The locking block 510 is used to clamp the first gear 506, the second gear 508 and the third gear 509 so that they are fixed on the mounting column 517 for rotation. At the same time, the first gear 506, the second gear 508 and the third gear 509 are used to control the rotation of the second positioning wheel 504 to facilitate the feeding and stopping of the welding wire. The first positioning wheel 503 and the second positioning wheel 504 are in contact with the surface of the welding wire to form an upper and lower two-layer guide structure to ensure that the welding wire remains straight in the clamping state and prevent cutting errors caused by offset.

[0043] The electric telescopic rod 702 is automatically extended according to the diameter and length of the welding wire, and the rubber plate 703 at the lower end is lightly pressed on the surface of the welding wire to form multi-point elastic support, thereby reducing the sagging of the long welding wire due to its own weight and avoiding deformation caused by hard squeezing. In addition, by starting the third servo motor 603 to drive the third screw rod 604 to rotate, the second slider 605 threaded on the third screw rod 604 moves up and down along the second slide groove 602, driving the cutter 606 to achieve precise lifting and lowering in the vertical direction. The cutter 606 cuts the welding wire by the downward movement of the second slider 605, meeting the size requirements of high-quality welding wire.

[0044] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
