Description

Technical Field

[0001] This application relates to special welding wire butt welding technology, and more particularly to a special welding wire butt welding device. Background Technology

[0002] Wire butt welding is performed using a small-scale combination welding machine. Wire butt welding ensures continuous wire supply in the welding process and effectively reduces welding defects. When butt welding wires, precise control of the welding heat input and tip pressure is required to ensure the joint strength meets the welding process requirements.

[0003] The pressure that welding wires can withstand at the joint varies depending on their diameter and hardness. Existing welding wire splicing devices cannot adjust the rebound force of the slide. When splicing thinner, lower-hardness welding wires, a slide with a high rebound force will cause the joint of the two wires to bend, affecting the welding effect. When splicing thicker, higher-hardness welding wires, a slide with a low rebound force cannot press the joint of the two wires tightly. This not only makes the welding wire splicing process difficult but also easily affects the quality of the welded wires. Utility Model Content

[0004] This application provides a special welding wire butt welding device to solve the problem that existing welding wire butt welding devices cannot adjust the pressure at the butt joint according to the type of welding wire.

[0005] This application provides a special welding wire butt welding device, including a body. The upper end of the body is provided with a fixed platform and a slide. The slide is slidably connected to a groove on the top surface of the body. The adjacent two side edges of the fixed platform and the slide are respectively connected with pressure arms. The upper end of the pressure arms is a clamping block for holding the welding wire. An adjusting cylinder threadedly connected to the side end of the slide along the sliding direction is inserted into the slide. A positioning plate is fixed between the grooves in the slide. The end of the adjusting cylinder facing the positioning plate is open. A tension spring is provided in the adjusting cylinder and fixed to one end there. The other end of the tension spring is rotatably connected to the positioning plate.

[0006] Optionally, the two pressure arms are respectively provided with fixing plates on both sides, which are fixed to the fixing table and the slide table. A straightener is installed on the fixing plate, and the outlet of the straightener corresponds to the clamping part of the clamping block.

[0007] Optionally, a motor for driving the straightener is mounted on the bottom of the fixing plate.

[0008] Optionally, a through groove is provided between the slides below the slide table, and the through groove can communicate with the gap formed between the fixed table and the slide table. A fan is installed on the through groove at the side end of the machine body.

[0009] The special welding wire butt welding device provided in this application uses the tension provided by the rebound of a tension spring to butt and press the two welding wires together when they are clamped between the clamping blocks of the fixed table and the slide table, ensuring the stability of the weld. An adjusting cylinder passes through the threaded connection of the slide table; rotating the adjusting cylinder adjusts its length inside the slide table, changing the rebound tension of the tension spring. This allows for timely adjustment of the spring's rebound tension according to the diameter and hardness of the welding wire, enabling the two welding wires to be butt-jointed and pressed together without bending.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0018] like Figures 1-4As shown, one embodiment of this application provides a special welding wire butt welding device, including a body 1. The upper end of the body 1 is provided with a fixed platform 2 and a slide 3. The slide 3 is slidably connected to the slide groove 4 on the top surface of the body 1. The adjacent two side edges of the fixed platform 2 and the slide 3 are respectively connected with pressure arms 5. The upper end of the pressure arm 5 is a clamping block 6 for clamping the welding wire. An adjusting cylinder 10 threadedly connected to the side end of the slide 3 along the sliding direction is inserted. A positioning plate 9 is fixed between the slide grooves 4 in the slide 3. The end of the adjusting cylinder 10 facing the positioning plate 9 is opened. A tension spring 11 is provided in the adjusting cylinder 10 and fixed to one end thereto. The other end of the tension spring 11 is rotatably connected to the positioning plate 9.

[0019] In use, first, rotate the eccentric wheel 7, causing the slide table 3 to slide along the slide groove 4 and form a gap with the fixed table 2 via the top wheel 8. Then, press the pressure arm 5 to open the clamping block 6, clamping the two welding wires to be welded between the clamping blocks 6 on the fixed table 2 and the slide table 3 respectively. Finally, rotate the eccentric wheel 7, causing the slide table 3 to move towards the fixed table 2 through the tension of the tension spring 11, so that the welding joints of the two welding wires are aligned. Then, start the welding machine button on the machine body 1 to perform the welding.

[0020] The adjusting cylinder 10 passes through the side wall of the slide table 3 and is threadedly connected to it. The tension spring 11 fixed inside the adjusting cylinder 10 is rotatably connected to the positioning plate 9. Rotating the adjusting cylinder 10 can adjust its length extending into the slide table 3. The longer the part of the adjusting cylinder 10 extends into the slide table 3, the smaller the pressure applied between the two welding wires when the tension spring 11 rebounds. Conversely, the longer the part of the adjusting cylinder 10 outside the slide table 3, the greater the pressure applied between the two welding wires when the tension spring 11 rebounds.

[0021] In this embodiment, when the two welding wires are clamped between the clamping blocks 6 of the fixed platform 2 and the slide 3, they are joined and pressed together by the tension provided by the rebound of the tension spring 11 to ensure the stability of the welding. The adjusting cylinder 10 passes through the threaded connection of the slide 3. Rotating the adjusting cylinder 10 can adjust its length extending into the slide 3, changing the rebound tension of the tension spring 11. The rebound tension of the tension spring 11 can be adjusted in time according to the diameter and hardness of the welding wire, so that the two welding wires can be joined and pressed together without bending.

[0022] In one possible implementation, the two pressure arms 5 are respectively provided with fixing plates 12 fixed to the fixing table 2 and the slide table 3 on both sides, and a straightener 13 is installed on the fixing plate 12, the outlet of the straightener 13 corresponding to the clamping part of the clamping block 6.

[0023] After being straightened by the straighteners 13 on both sides of the pressure arm 5, the two welding wires are inserted into the clamping block 6 for clamping and fixing. When the welding wires straightened by the straighteners 13 are pressed together, the force is more even and they are less likely to bend.

[0024] In one possible implementation, a motor 14 for driving the straightener 13 is mounted on the bottom of the fixing plate 12.

[0025] The straightener 13 is driven by motor 14 to straighten the welding wire, which is convenient, labor-saving and improves the straightening efficiency.

[0026] In one possible implementation, a through groove 15 is provided between the slide grooves 4 below the slide table 3. The through groove 15 can communicate with the gap formed between the fixed table 2 and the slide table 3. A fan 16 is installed on the through groove 15 on the side of the body 1.

[0027] The through groove 15 is connected to the gap between the fixed table 2 and the slide table 3. The fan 16 connects the welding wire joint held by the welding wire in the through groove 15, the gap and the clamping block 6 to form an air duct, which cools down the electrode system of the machine body 1 and the welding wire joint, so as to avoid the equipment overheating and the welding quality deterioration.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
