[0034] like Figures 1-4 As shown, it illustrates an automatic welding mechanism for a pipe welding machine according to this disclosure, comprising:
[0035] Feed box 1, and a welding station 2 is provided on one side of the feed box 1;
[0036] The welding support assembly 3 is mounted on the welding table 2.
[0037] Feed cleaning component 4 is installed inside the feed box 1;
[0038] The welding support assembly 3 includes a welding frame 3-1, which is set on the welding table 2. A support frame 3-2 is inserted into the welding table 2. A lower pressure frame 3-3 is connected to the upper end of the support frame 3-2 by a pin. A welding plate 3-4 is set on the lower pressure frame 3-3. A welder 3-5 is set at the lower end of the welding plate 3-4. A welding gun 3-6 is set at the lower end of the welder 3-5. A handle 3-7 is set on the lower pressure frame 3-3. A drop opening 3-8 is opened on the welding table 2. A collection cover 3-9 is set on the drop opening 3-8. A collection port 3-10 is set at the lower end of the collection cover 3-9.
[0039] The feeding cleaning component 4 includes a feeding hole 4-1, which is located on the feeding box 1. A cleaning chamber 4-2 is provided inside the feeding hole 4-1. A cleaning frame 4-3 is provided inside the cleaning chamber 4-2. A cleaning brush 4-4 is provided on the cleaning frame 4-3. A cleaning port 4-5 is provided at the lower end of the cleaning chamber 4-2.
[0040] In some examples, the welding station 2 is installed on the side wall of the feed box 1 and fixed with appropriate bolts and nuts. Then, a reinforcing rib 12 is installed between the welding station 2 and the feed box 1. The connection between the two is ensured to be stable by welding or bolting, thereby enhancing the stability of the overall structure.
[0041] Place the positioning plate 6 into the positioning hole 5 on the welding table 2, so that the positioning plate 6 fits tightly with the positioning hole 5. Align the positioning strip 9 on the support frame 3-2 with the expansion groove 8 on the insertion hole 7 of the positioning plate 6, insert it and ensure that the positioning strip 9 fits completely with the expansion groove 8. Then, fix the limiting plate 10 on the support frame 3-2 so that the limiting plate 10 and the positioning plate 6 fit together to further fix the position of the support frame 3-2.
[0042] Install a fixing frame 13 on the welding table 2, connect the lower end of the welding frame 3-1 to the fixing frame 13, and secure it by welding or bolts to ensure the stability of the welding frame 3-1. Install a rubber semi-circular protective sleeve on the inner wall of the welding frame 3-1 to provide protection for subsequent welding operations.
[0043] Connect the upper end of the support frame 3-2 to the lower pressure frame 3-3 with a pin to ensure that the lower pressure frame 3-3 can rotate freely. Install the welding disc 3-4 on the lower pressure frame 3-3 and secure it firmly with bolts. Install the welder 3-5 at the lower end of the welding disc 3-4, and then install the welding gun 3-6 at the lower end of the welder 3-5, ensuring that the welding gun 3-6 is accurately positioned. Finally, install the handle 3-7 on the lower pressure frame 3-3 for easy operation.
[0044] The pipe to be welded is put into the feed hole 4-1 of the feed box 1. The pipe enters the cleaning chamber 4-2 through the expansion port 14. In the cleaning chamber 4-2, the cleaning brush 4-4 on the cleaning frame 4-3 will clean the surface of the pipe to remove dust, dirt and other impurities. After cleaning, the pipe enters the welding position through the limiting tube 4-7.
[0045] According to the diameter of the pipe and the welding requirements, adjust the position of the lower pressure frame 3-3 by holding the handle 3-7 to keep the welding gun 3-6 at a suitable distance and angle from the surface of the pipe. At the same time, ensure that the welding disc 3-4, welding device 3-5 and other components are in normal working condition.
[0046] like Figures 1-4 As shown, this embodiment proposes that a limiting sleeve 3-11 be provided on the welding frame 3-1, a limiting port 3-12 be provided on the limiting sleeve 3-11, a rotation shaft 3-13 be provided inside the limiting port 3-12, and a rotation wheel 3-14 be fitted on the rotation shaft 3-13.
[0047] In some examples, the limiting port 3-12 on the limiting sleeve 3-11 is used to house the rotation shaft 3-13, and the rotation wheel 3-14 on the rotation shaft 3-13 can provide rotation for the welded pipe.
[0048] For example, such as Figure 4 As shown, an arc-shaped discharge block 4-6 is provided at the bottom of the cleaning chamber 4-2, and a limit tube 4-7 is provided on the side wall of the feed box 1. The limit tube 4-7 is connected to the feed hole 4-1.
[0049] In some examples, an arc-shaped discharge block 4-6 is installed at the bottom of the cleaning chamber 4-2 to guide impurities to be discharged smoothly, and a limiting tube 4-7 is installed on the side wall of the feed box 1 and connected to the feed hole 4-1 to limit the pipe entering the feed hole 4-1.
[0050] For example, such as Figure 2 As shown, the welding table 2 is provided with a positioning hole 5, a positioning plate 6 is provided in the positioning hole 5, an insertion hole 7 is provided on the positioning plate 6, an expansion groove 8 is provided on the insertion hole 7, and a positioning strip 9 is provided on the support frame 3-2, which is inserted into the expansion groove 8.
[0051] In some examples, the positioning strip 9 on the support frame 3-2 is inserted into the expansion groove 8 of the positioning plate 6. The positioning strip 9 can swing within the expansion groove 8 to a certain extent, which can be used for fine-tuning of the welding gun 3-6 at a small angle.
[0052] For example, such as Figure 2 As shown, a limiting plate 10 is fixedly mounted on the support frame 3-2, and the limiting plate 10 is in contact with the positioning plate 6.
[0053] In some examples, the support frame 3-2 is accurately positioned by the fit between the limiting plate 10 and the positioning plate 6, thus ensuring the stability of the welding frame 3-1 during the welding process.
[0054] For example, such as Figure 1 As shown, the lower end face of the welding table 2 is provided with a supporting leg 11, which is located on the same side edge of the welding table 2. The welding table 2 is located on the side wall of the feed box 1. A reinforcing rib 12 connects the welding table 2 and the feed box 1. A fixing frame 13 is provided at the lower end of the welding frame 3-1. The fixing frame 13 is located on the welding table 2. A protective sleeve is provided on the inner side wall of the welding frame 3-1. The protective sleeve is a semi-circular structure made of rubber.
[0055] In some examples, a support leg 11 is installed on the same side edge of the lower end face of the welding table 2. The support leg 11 is fixed to the welding table 2 by welding or high-strength bolts to ensure that the welding table 2 is placed stably and to provide a stable foundation for subsequent component installation.
[0056] For example, such as Figure 4 As shown, one end of the feed hole 4-1 is provided with an expansion port 14, which has a frustum-shaped structure.
[0057] In some examples, an expansion port 14 is installed at one end of the feed hole 4-1 to facilitate the smooth entry of the pipe into the feed hole 4-1.
[0058] During use, align one end of the pipe to be welded with the expansion port 14 of the feed hole 4-1. The expansion port 14 has a frustum-shaped structure, facilitating smooth entry of the pipe. Slowly push the pipe into the cleaning chamber 4-2 within the feed hole 4-1. As the pipe passes through the cleaning chamber 4-2, the cleaning brushes 4-4 on the cleaning frame 4-3 clean the surface of the pipe, removing dust, rust, and other impurities. The removed impurities will be discharged along the arc-shaped discharge block 4-6 and exit from the cleaning port 4-5. After cleaning, the pipe passes through the limiting tube 4-7, which further restricts the feeding direction and position of the pipe, ensuring the pipe accurately reaches the welding position. Adjust the angle and height of the lower pressure frame 3-3 by holding the handle 3-7 to maintain a suitable distance and angle between the welding gun 3-6 and the pipe surface. Generally, the distance is 3- 5mm, the angle is determined according to the welding process. Turn on the power of the welding equipment and start the welder 3-5 to make the welding gun 3-6 start working. Adjust the welding current, voltage and welding speed according to the material and thickness of the pipe to achieve the best welding effect. During the welding process, the self-rotating wheel 3-14 on the welding frame 3-1 can be used to rotate within the limit port 3-12 through the self-rotating shaft 3-13 to facilitate the adjustment of the pipe position and make the welding more uniform. Closely observe the welding process, pay attention to the working status of the welding gun 3-6, the formation of the weld and the heating of the pipe. If defects such as porosity, cracks or lack of fusion are found in the weld, welding should be stopped in time, the welding parameters should be adjusted or the equipment should be checked, and welding should be continued after the problem is eliminated. At the same time, pay attention to the condition of the collection hood 3-9 and the collection port 3-10, and clean up the welding spatter and debris collected at the drop port 3-8 in time.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
