Description

Technical Field

[0001] The utility model relates to the field of aluminum tube welding, in particular to a welding wire forming mechanism for aluminum tube welding assembly. Background Art

[0002] Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material made of pure aluminum or aluminum alloy through extrusion and is hollow along its entire longitudinal length. It may have one or more closed through holes, with uniform wall thickness and cross section, and is delivered in a straight line or in a roll. It is widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home furnishing and other industries. Aluminum tubes are mainly divided into the following types according to their appearance: square tubes, round tubes, patterned tubes, special-shaped tubes, and round aluminum tubes. According to the extrusion method, they are divided into seamless aluminum tubes and ordinary extruded tubes. Aluminum tubes are often welded and assembled using welding wires when in use.

[0003] After massive searches, it was found that the Chinese patent with the prior art publication number CN219851831U disclosed a welding wire forming mechanism for aluminum tube welding assembly. The patent uses the aluminum tube to press the welding wire into the arc welding wire placement groove by the operator, and then the abutment roller on one side of the left placement seat approaches the welding wire, so that the welding wire located outside the arc welding wire placement groove is attached to the outer wall of the aluminum tube, and then the abutment roller moves upward until the welding wire on this side is completely attached to the outer wall of the aluminum tube, and then the abutment roller on the other side of the left placement seat moves to attach all the welding wire on the other side to the outer wall of the aluminum tube. During the whole process, the labor intensity of the operator is small, but in this scheme, due to the smooth surface of the abutment roller, it is difficult for the abutment roller to locate the position of the welding wire, resulting in the staff using the abutment roller to wrap the welding wire around the aluminum tube, and the welding wire may deviate from the predetermined position, affecting the subsequent welding of the aluminum tube. Therefore, based on the above search and combined with the prior art, the utility model proposes a welding wire forming mechanism for aluminum tube welding assembly to solve the above problems.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, A wire forming mechanism for aluminum tube welding and assembly, including a workbench 1. On the top surface of the workbench 1, a ceiling 2 is fixedly installed. On the top surface of the workbench 1, two observation plates 3 for observing the aluminum tube welding situation are fixedly installed. The observation plate 3 is a transparent acrylic rectangular structure. On the top surface of the workbench 1, a positioning seat 15 is installed. The positioning seat 15 is fixedly installed on the top surface of the workbench 1 through a bracket. The positioning seat 15 can support the aluminum tube. A wire inlet groove 19 for accommodating the welding wire is opened on the inner circumferential wall surface of the positioning seat 15. Above the positioning seat 15, a positioning component 6 for positioning the welding wire is provided. On the top surface of the workbench 1, a clamping component 7 for clamping the aluminum tube is provided;

[0024] The positioning component 6 includes two extrusion blocks 23. Both of the two extrusion blocks 23 are arranged on the top surface of the workbench 1. Two positioning rings 24 are movably sleeved on the outer circumferential wall surface of the extrusion block 23. On one side of the extrusion block 23, a limiting member for restricting the movement of the positioning ring 24 is provided. The limiting member includes a chute 8. The chute 8 is opened on one side of the extrusion block 23. Both sides inside the chute 8 are inclined towards the center position of the chute 8. On one side inside the positioning ring 24, a slider 33 is fixedly installed. The slider 33 is slidably connected with the chute 8. When the positioning ring 24 moves along the outer circumferential wall surface of the extrusion block 23, it will drive the slider 33 to slide inside the chute 8. The slider 33 can restrict the movement of the positioning ring 24 to achieve the limiting effect on the positioning ring 24;

[0025] On one side of the extrusion block 23, a connecting plate 22 is fixedly installed. On one side of the positioning ring 24, a support frame 25 is fixedly installed. Inside the support frame 25, a support rod 27 is fixedly installed. Two support plates 26 are elastically connected to the outer circumferential wall surface of the support rod 27. A circular through hole is opened on one side of the support plate 26. The inner circumferential wall surface of the circular through hole is movably sleeved with the outer circumferential wall surface of the support rod 27. A second spring 28 is movably sleeved on the outer circumferential wall surface of the support rod 27. Both ends of the second spring 28 are fixedly connected to the two sides close to each other of the two support plates 26. On the top surface of the support plate 26, a connecting rod 18 is fixedly installed. Circular through holes are opened on both the top surface and the bottom surface of the support frame 25. The outer circumferential wall surface of the connecting rod 18 is movably sleeved with the inner circumferential wall surface of the circular through hole. On the top surface of the support plate 26, a clamping column 30 is fixedly installed. On both sides of the connecting plate 22, two support bars 29 are fixedly installed. A reinforcing rod is fixedly installed between the support bar 29 and the connecting plate 22. The reinforcing rod can reinforce the support bar 29. The clamping column 30 is movably clamped with the support bar 29. A number of clamping holes 31 are opened on the top surface of the support bar 29. The clamping column 30 is movably clamped with the clamping holes 31;

[0026] Through the provided positioning seat 15, the operator places the welding wire into the wire inlet groove 19 inside the positioning seat 15 while ensuring that the lengths of the welding wire extending beyond both ends of the positioning seat 15 are approximately the same. The operator places two aluminum tubes inside the positioning seat 15. The operator adjusts the positions of the two positioning rings 24 on the extrusion block 23 according to the radius of the welding wire. The operator squeezes the two connecting rods 18, causing the connecting rods 18 to move inward. The inward movement of the connecting rods 18 drives the support plate 26 to move inward along the support rod 27 inside the support frame 25 while compressing the second spring 28. The inward movement of the support plate 26 also drives the clamping post 30 to move inward to the outside of the clamping hole 31 on the support bar 29. Without the restriction of the clamping post 30, the operator moves the support frame 25 inward, driving the positioning ring 24 to move inward along the extrusion block 23 until the welding wire is clamped between the two positioning rings 24. Then, the operator releases the two connecting rods 18. The acting force of the second spring 28 causes the two support plates 26 to drive the clamping post 30 to move outward. The outward movement of the clamping post 30 will enter the inside of the clamping hole 31 on the support bar 29, thereby determining the positions of the two positioning rings 24. At this time, the two positioning rings 24 can position the welding wire, preventing the welding wire from deviating from the predetermined position and avoiding the displacement of the welding wire when the welding wire is wound around the aluminum tube later, achieving the positioning effect of the welding wire and facilitating the operator to weld the two aluminum tubes into shape using the welding wire;

[0027] On the top surface of the workbench 1, two support boxes 20 are provided. Inside the support box 20, a movable column 21 is elastically connected. On one side inside the support box 20, a first spring 11 is fixedly installed. One end of the first spring 11 is fixedly connected to one side of the movable column 21. One side of the movable column 21 is fixedly connected to one side of the connecting plate 22. On the top surface of the workbench 1, an electric push rod 16 for moving the support box 20 is fixedly installed. One end of the telescopic shaft of the electric push rod 16 is fixedly connected to the bottom surface of the support box 20. On both sides of the support box 20, limiting members for restricting the movement of the movable column 21 are provided. On one side of the workbench 1, a PLC controller is fixedly installed. The PLC controller is electrically connected to the electric push rod 16;

[0028] Through the provided positioning seat 15, the operator places the aluminum tube inside the positioning seat 15 such that the positioning ring 24 abuts against the outer wall of the aluminum tube. The operator starts the electric push rod 16. The upward movement of the telescopic shaft of the electric push rod 16 drives the support box 20, the extrusion block 23, and the positioning ring 24 to move upward. During the process of the support box 20 driving the positioning ring 24 to move upward, the acting force of the first spring 11 causes the movable column 21 to drive the extrusion block 23 and the positioning ring 24 to move outward, such that the positioning ring 24 always abuts against the aluminum tube and the extrusion block 23 and the positioning ring 24 will squeeze the welding wire, causing the welding wire to be wound around the aluminum tube, thereby winding the welding wire onto the aluminum tube.

[0029] Example 2: Please refer to Figure 1 、 Figure 2 、 Figure 3, Figure 4 and Figure 6 , a wire forming mechanism for aluminum tube welding and assembly. The limiting member includes two limiting holes 17, which are respectively opened on both sides of the support box 20. Limiting blocks 32 are fixedly installed on both sides of the movable column 21, and the limiting blocks 32 are slidably connected to the limiting holes 17. By setting the movable column 21, when the movable column 21 moves outward, it drives the limiting blocks 32 to move outward inside the limiting holes 17 of the support box 20, and the limiting blocks 32 can limit the movement of the movable column 21, achieving the limiting effect on the movable column 21;

[0030] The clamping assembly 7 includes two support seats 12, both of which are fixedly installed on the top surface of the workbench 1. The support seats 12 can support one end of the aluminum tube. A clamping plate 10 is arranged on the top surface of the support seat 12, and a hydraulic cylinder 9 for moving the clamping plate 10 is fixedly installed on the inner top surface of the ceiling 2. The bottom surface of the telescopic shaft of the hydraulic cylinder 9 is fixedly connected to the outer circumferential wall surface of the clamping plate 10. The hydraulic cylinder 9 is electrically connected to the PLC controller. By setting the positioning seat 15, after the staff places the aluminum tube inside the positioning seat 15, the other end of the aluminum tube will be inside the support seat 12. The staff starts the hydraulic cylinder 9, and the telescopic shaft of the hydraulic cylinder 9 moves downward to drive the clamping plate 10 to move downward until it abuts against the outer wall of the aluminum tube, thereby clamping the aluminum tube;

[0031] Two welding torch bodies 13 are fixedly installed on the top surface of the workbench 1. An air inlet pipe 14 for air intake is fixedly sleeved on the inner circumferential wall surface of the air inlet hole of the welding torch body 13. The welding torch body 13 is electrically connected to the PLC controller. Two round holes are opened on one side of the ceiling 2, and the outer circumferential wall surface of the air inlet pipe 14 is fixedly sleeved with the inner circumferential wall surface of the round holes. A protective curtain 4 for blocking sparks is fixedly installed on one side of the ceiling 2, and a magnetic strip 5 is fixedly installed on the bottom surface of the protective curtain 4. When using the welding torch body 13 to weld the aluminum tube, the protective curtain 4 can block the sparks generated by the welding torch body 13. When not welding the aluminum tube, the staff flips the protective curtain 4 outward so that the magnetic strip 5 on the protective curtain 4 contacts the top surface of the ceiling 2, and the magnetic strip 5 can adsorb the ceiling 2, thereby restricting the protective curtain 4 on the ceiling 2;

[0032] By setting the positioning seat 15, after winding the welding wire around the outer wall of the aluminum tube, the staff connects natural gas to the air inlet pipe 14, and then the welding torch body 13 heats the aluminum tube. The temperature of the aluminum tube is transferred to the welding wire, causing the welding wire to melt, thereby welding two sections of the aluminum tube into a shape.

[0033] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
