Description

Technical Field

[0001] The present invention belongs to the field of welding technology, and specifically relates to a device for adjusting the movement of a welding wire during welding, which can adjust the movement state of the welding wire during welding, avoid splashing caused by excess liquid welding wire, effectively solve the problem of excess welding slag on the profile after welding, and reduce the waste of welding wire material. Background Art

[0002] Welding, as one of the commonly used technologies in industry, is a manufacturing process and technology that combines metals or other thermoplastic materials by heating at high temperatures or high pressures. It can be divided into three categories according to the welding method: fusion welding, pressure welding, and brazing. Some of these welding methods require other metals as solder to fill the weld, so welding wire is required. However, since the welding wire is continuously fed by the wire feeding mechanism during the automatic welding process, the previous section of solder has not yet solidified, and the wire feeding mechanism squeezes out the next section of solder, forming spattering slag. This makes part of the welding wire not fully utilized, resulting in waste and high welding costs. In addition, the excess liquid welding wire splashes on the welding surface, resulting in reduced surface accuracy of the workpiece. Therefore, in order to reduce the waste of welding wire and avoid the appearance of excess welding slag on the profile, it is necessary to improve the device used to adjust the movement state of the welding wire during the welding process. Summary of the Invention

[0003] The present invention is aimed at the above-mentioned problems and provides a device for adjusting the movement of the welding wire during the welding process, which can adjust the movement state of the welding wire, avoid splashing caused by excess liquid welding wire, effectively solve the problem of excess welding slag on the profile after welding, and reduce the waste of welding wire material.

[0004] The technical solution adopted by the present invention is: the adjustment device for the movement of the welding wire during welding includes a base plate, and is characterized in that: a gantry-type adjustment guide frame is provided on the base plate, an upper guide block is provided on the upper part of the gantry-type adjustment guide frame, an inner guide frame is provided below the gantry-type adjustment guide frame, the lower part of the inner guide frame is connected to the base plate, and a lower guide block is provided on the upper part of the inner guide frame; and a welding wire pulling mechanism is provided between the lower guide block and the upper guide block, the welding wire pulling mechanism is also connected to the voice coil motor, and the voice coil motor is connected to the base plate through a motor connection base.

[0005] The gantry-type adjustment guide frame includes two sets of outer support vertical plates, each of which has a transverse plate position adjustment slot disposed at its upper end. Furthermore, an upper transverse connecting plate is disposed between the upper ends of the two sets of outer support vertical plates. The ends of the upper transverse connecting plate are connected to the transverse plate position adjustment slots via adjustment bolts disposed in fastening bolt holes. A welding wire passage opening is disposed in the middle of the upper transverse connecting plate. The vertical relative distance between the upper transverse connecting plate of the gantry-type adjustment guide frame and the welding wire pulling mechanism below it can be adjusted by moving the upper transverse connecting plate up and down along the transverse plate position adjustment slots on the outer support vertical plates on both sides.

[0006] The upper guide block includes an upper guide block body, a wire inlet hole provided in the middle of the upper guide block body, and two ends of the upper guide block body connected to two sides of the upper transverse connecting plate via guide block side pressure plates. One end of the guide block side pressure plate is crimped onto the end of the upper guide block body, and the other end of the guide block side pressure plate is crimped onto a pressure plate pad provided on the side of the upper transverse connecting plate. The guide block side pressure plates are connected to the pressure plate mounting holes on the side of the upper transverse connecting plate via connecting bolts. The upper guide block body is adjustably mounted on the upper transverse connecting plate using the guide block side pressure plates on both sides, facilitating movement and adjustment of the upper guide block on the upper portion of the gantry-type adjustment guide frame. Furthermore, the upper guide block body can be flexibly replaced according to actual conditions to simulate a variety of different pipe diameters at the inlet end of the welding wire pipe.

A wire drawing movable block is also provided on the upper side of the wire drawing slide seat, and the wire drawing movable block is connected to the wire drawing slide seat via an L-shaped connecting side plate. The translational drive unit of the voice coil motor is utilized to drive the wire drawing slide seat to move back and forth, thereby achieving a reciprocating radial force on the welding wire inserted into the welding wire pulling mechanism. The high-frequency motion of the voice coil motor pulls the welding wire up and down, that is, the vertically downward welding wire is pulled out of the inclination angle, achieving high-frequency intermittent upward jumps of the welding wire. The combination of the welding wire pulling mechanism and the welding gun can greatly improve the utilization rate of the welding wire and reduce liquid splashing during welding.

A lower guide block is disposed between the upper ends of the two sets of inner support vertical plates, with both sides of the lower guide block connected to the lower guide block position adjustment slot via adjustable fastening bolts. A wire outlet hole is disposed in the middle of the lower guide block. The vertical relative distance between the lower guide block of the inner guide frame and the wire pulling mechanism above it is adjusted by moving the lower guide block up and down along the lower guide block position adjustment slots on the inner support vertical plates on both sides. The lower guide block with the wire outlet hole simulates a wire outlet pipe.

[0011] The upper guide block of the gantry-type adjustment guide frame, the lower guide block of the inner guide frame, and the wire pulling mechanism are centrally symmetrical with respect to the support plates on both sides of the gantry-type adjustment guide frame, so as to ensure that the wire will not be broken during the process of adjusting the movement of the wire.

[0012] The wire threading hole on the upper guide block, the wire threading hole on the lower guide block and the wire threading hole on the wire pulling mechanism are kept coaxial at the initial position, so as to facilitate the welding wire to pass through the wire threading holes on each guide block and the wire pulling mechanism and facilitate initial alignment.

DETAILED DESCRIPTION

[0022] according to Figures 1 to 7 The specific structure of the present invention is described in detail. The regulating device for the movement of the welding wire during welding comprises a base plate 1, and metal hoof feet 9 are respectively provided on the lower side of the four corners of the base plate 1. A gantry-type regulating guide frame 2 is provided on the base plate 1, and an upper guide block 3 (such as Figure 1 and Figure 2 As shown). The gantry-type adjustment guide frame 2 includes two groups of outer support vertical plates 10, the lower ends of the outer support vertical plates 10 are connected to the bottom plate 1, and the upper ends of the outer support vertical plates 10 are provided with vertically arranged transverse plate position adjustment slots 12; and, between the upper ends of the two groups of outer support vertical plates 10, a transversely arranged upper transverse connecting plate 11 is further provided, and the two ends of the upper transverse connecting plate 11 are respectively connected to the transverse plate position adjustment slots 12 by adjusting fastening bolts 13 provided in fastening bolt holes 16 (as shown). Figure 3 A wire passage opening 14 is provided in the middle of the upper transverse connecting plate 11. Furthermore, the vertical relative distance between the upper transverse connecting plate 11 of the gantry-type adjustment guide frame 2 and the wire pulling mechanism 4 below it is adjusted by moving the upper transverse connecting plate 11 up and down along the transverse plate position adjustment slots 12 on the outer support vertical plates 10 on both sides.

[0023] The upper guide block 3 at the top of the gantry-type adjustment guide frame 2 is composed of an upper guide block body 17. A wire entry hole 18 is provided in the middle of the upper guide block body 17. The two ends of the upper guide block body 17 are connected to the two sides of the upper transverse connecting plate 11 through guide block side pressure plates 20. At the same time, one end of the guide block side pressure plate 20 is pressed against the end of the upper guide block body 17, and the other end of the guide block side pressure plate 20 is pressed against the pressure plate pad 21 provided on the side of the upper transverse connecting plate 11.

Figure 4As shown in the figure, the upper guide block body 17 is adjustably mounted on the upper transverse connecting plate 11 using the guide block side pressure plates 20 on either side, facilitating the movement and adjustment of the upper guide block 3 above the gantry-type adjustable guide frame 2. Furthermore, the upper guide block body 17 can be flexibly replaced according to actual conditions to simulate a variety of different pipe diameters at the welding wire inlet, facilitating the use of the device. Furthermore, auxiliary sleeve mounting holes 19 are provided on the upper guide block body 17 on either side of the wire inlet hole 18. Auxiliary sleeves can be installed through these holes, facilitating the insertion of welding wire.

[0024] An inner guide frame 7 is also provided below the gantry-type adjustment guide frame 2. The lower portion of the inner guide frame 7 is connected to the base plate 1, and a lower guide block 8 is provided on the upper portion of the inner guide frame 7. The inner guide frame 7 includes two sets of inner support vertical plates 31. The upper ends of the inner support vertical plates 31 are provided with lower guide block position adjustment slots 32, and the lower guide block 8 is provided between the upper ends of the two sets of inner support vertical plates 31. The two sides of the lower guide block 8 are respectively connected to the lower guide block position adjustment slots 32 by adjusting fastening bolts 13. The middle portion of the lower guide block 8 is provided with a wire outlet end threading hole 33 (such as Figure 7 The vertical relative distance between the lower guide block 8 of the inner guide frame 7 and the welding wire pulling mechanism 4 above it is adjusted by moving the lower guide block 8 up and down along the lower guide block position adjustment chute 32 on the inner support vertical plates 31 on both sides. The lower guide block 8 with the wire outlet hole 33 is used to simulate the outlet pipe of the welding wire. The flexibly replaceable lower guide block 8 can also be used to simulate a variety of pipe diameters at the outlet of the welding wire pipe.

[0025] Furthermore, a wire drawing mechanism 4 is provided between the lower guide block 8 of the inner guide frame 7 and the upper guide block 3 of the gantry-type adjustment guide frame 2. The wire drawing mechanism 4 is also connected to the voice coil motor 5, which is connected to the bottom plate 1 via the motor connection base 6. The wire drawing mechanism 4 includes a wire drawing sliding seat 23, which is slidably provided on a sliding guide rail 24 on the upper side of the motor connection base 6, and one end of the wire drawing sliding seat 23 is connected to the translational drive portion 22 of the voice coil motor 5. A wire drawing movable block 26 is also provided on the upper side of the wire drawing sliding seat 23, and the wire drawing movable block 26 is connected to the wire drawing sliding seat 23 via an L-shaped connecting side plate 25 (as shown in FIG. Figure 5 shown).

[0026] The wire drawing block 26 is composed of a moving block body 27. The front end of the moving block body 27 is provided with a front probe wire drawing head 28. The front probe wire drawing head 28 is provided with a plurality of wire drawing holes 29. The rear part of the moving block body 27 is provided with a side plate connecting hole 30 (such as Figure 6As shown); the wire drawing movable block 26 is fixedly connected to the wire drawing sliding seat 23 through the L-shaped connecting side plate 25 connected to the side plate connecting hole 30, and the multiple wire drawing through-holes 29 provided on the front probe wire drawing head 28 are used to facilitate the adjustment of the insertion position of the welding wire on the wire drawing mechanism 4. At the same time, the translational drive part 22 of the voice coil motor 5 is used to drive the wire drawing sliding seat 23 to move back and forth, so as to realize the reciprocating radial force effect on the welding wire inserted into the wire drawing mechanism 4. The high-frequency movement of the voice coil motor 5 pulls the welding wire up and down, that is, the vertically downward welding wire is pulled out of the inclination angle to realize the high-frequency intermittent upward jump of the welding wire. Ensure that the output force of the voice coil motor 5 meets the requirements and the movement frequency is sufficient, and it has adjustability for different types of welding wires; the combination of the wire drawing mechanism 4 and the welding gun can greatly improve the utilization rate of the welding wire and reduce liquid splashing during welding.

[0027] The upper guide block 3 of the gantry-type adjustable guide frame 2, the lower guide block 8 of the inner guide frame 7, and the wire pulling mechanism 4 maintain central symmetry relative to the support plates on both sides of the gantry-type adjustable guide frame 2 to ensure that the welding wire cannot be broken during the process of adjusting the movement of the welding wire. Moreover, the wire threading holes on the upper guide block 3, the wire threading holes on the lower guide block 8, and the wire threading holes on the wire pulling mechanism 4 remain coaxial in their initial positions, thereby facilitating the passage of the welding wire through the wire threading holes on each guide block and the wire pulling mechanism 4, thereby facilitating initial alignment. The upper transverse connecting plate 11 of the gantry-type adjustable guide frame 2 and the upper guide block 3 thereon have a vertical adjustment range of 0mm to 40mm from the wire pulling mechanism 4 below them; the lower guide block 8 of the inner guide frame 7 also has a vertical adjustment range of 0mm to 40mm from the wire pulling mechanism 4 above it; therefore, the adjustment range between the upper guide block 3 and the lower guide block 8 can reach 80mm. Within this adjustment range, the moving welding wire achieves a wider frequency bandwidth. By adjusting the relative position, the optimal position of different welding wire types within the device can be determined. The wire's movement frequency is determined by the travel and tension of the voice coil motor 5, as well as factors such as the wire's stiffness and heat resistance. Therefore, when adjusting the wire's movement, it is crucial to ensure that the wire does not break. The appropriate adjustment range must be selected to achieve high-frequency upward movement of the wire during welding.

[0028] When using this device for adjusting the movement of the welding wire during welding, first, the wire inlet hole 18 on the gantry-type adjustment guide frame 2, the wire outlet hole 33 on the inner guide frame 7, and the wire drawing hole 29 on the wire drawing mechanism 4 are kept coaxial in their initial positions. Then, the welding wire output by the wire feeding mechanism is sequentially passed through the upper guide block 3, the wire drawing movable block 26, and the lower guide block 8, and connected to the welding gun. After determining the type of welding wire and the speed of the wire feeding mechanism, the position of the upper guide block 3 on the upper transverse connecting plate 11 of the gantry-type adjustment guide frame 2 and the lower guide block 8 on the inner guide frame 7 can be manually adjusted to set the optimal adjustment scheme, find the optimal distance range, and provide the optimal input to the voice coil motor 5. During the automatic welding process, the linear drive part 22 of the voice coil motor 5 drives the wire drawing sliding seat 23 to move back and forth along the sliding guide rail 24, thereby pulling the vertically downward welding wire out of an inclination angle, and realizing high-frequency intermittent upward jumping of the welding wire; it effectively solves the problem that the welding wire continuously transported during the welding process cannot be used in time, reduces material waste, reduces welding costs, and solves the problem of welding slag residue on the workpiece surface caused by excess welding wire splashing.
