Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material made from stainless steel. Due to its unique corrosion resistance (excellent resistance to water, air, steam, and other chemicals) and heat resistance (able to withstand certain high temperatures, suitable for hot water transportation), it is widely used in various fields such as industry, construction, and daily life. To meet manufacturing needs, facilitate connection and installation, and accommodate customization requirements, we need to weld two sections of stainless steel pipe. Therefore, we urgently need a welding device for stainless steel pipes.

[0003] Currently, the welding of two sections of stainless steel pipe is done directly with a welding gun. However, when stainless steel is welded, it produces strong electric arc light (such as harmful light such as ultraviolet and infrared rays), which can damage the eyes and skin of operators (such as causing photokeratitis, skin burns, etc.). At the same time, high-temperature spatter is also produced during the welding process, which can easily burn the operators. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a welding device for stainless steel pipes. By improving the structure of the welding device, the operator can be protected, thereby improving the safety of stainless steel pipe welding.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A welding device for stainless steel pipes includes: a base, a welding mechanism, and a protective mechanism. The welding mechanism is located above the base and is used for welding two sections of stainless steel pipes. The protective mechanism includes: a first protective block and a second protective block. Both the first and second protective blocks are hollow structures and are rotatably connected to the base. A transparent protective plate is provided on the side of the first protective block away from the second protective block. When the first and second protective blocks are in a closed state, the welding mechanism and the welding joint of the two sections of stainless steel pipes are located within the sealed space formed by the first and second protective blocks.

[0007] Therefore, during the welding process of two stainless steel pipes, the first and second protective blocks, which are in a closed state, protect the operator. Compared with the existing welding methods without protective measures, this method has a simple structure and is easy to operate. By placing the two stainless steel pipes in the sealed space of the first and second protective blocks for welding, the intense electric arc light generated during the welding process can be avoided from causing damage to the operator's eyes and skin. It can also prevent the high-temperature spatter generated during the welding process from burning the operator. In this way, the operator can effectively protect the operator and improve the safety of stainless steel pipe welding operations. In addition, the operator can also observe the progress of the welding operation of the two stainless steel pipes in real time through the transparent protective plate.

[0008] As a further improvement to the above technical solution, it also includes: a connecting mechanism, the two ends of which are respectively installed on the first protective block and the second protective block; when the connecting mechanism is in the open state, both the first protective block and the second protective block can rotate relative to the base; when the connecting mechanism is in the closed state, the first protective block and the second protective block cannot rotate relative to the base, and the first protective block and the second protective block are in the closed state.

[0009] As a further improvement to the above technical solution: the connecting mechanism includes a connecting block and a snap-fit ​​block. The connecting block is connected to the first protective block, and the snap-fit ​​block is connected to the second protective block. Thus, through the cooperation of the connecting block and the snap-fit ​​block, the first and second protective blocks can be opened and closed. When the connecting block and the snap-fit ​​block are connected, the first and second protective blocks cannot rotate relative to the base due to the constraint of the connecting block and the snap-fit ​​block. This ensures that the welding operation of the two stainless steel pipes is carried out in a sealed space.

[0010] As a further improvement to the above technical solution, it also includes a filtration mechanism, which comprises an air purifier and a pump. The inlet end of the air purifier is connected to the sealed space formed by the first protective block and the second protective block, and the outlet end of the air purifier is connected to the pump. Both the air purifier and the pump are installed on the side wall of the first protective block. Therefore, during the welding process of the two stainless steel pipes, the air purifier can purify the toxic and harmful gases generated during the welding process. The purified gas is then extracted by the pump to prevent the direct discharge of toxic and harmful gases and environmental pollution.

[0011] As a further improvement to the above technical solution: the welding mechanism includes a first driving member and a welding gun. The welding gun is mounted on the telescopic end of the first driving member. The first driving member drives the welding gun to move up and down, so that the welding gun moves towards or away from the base. The welding gun is used to perform welding operations on two sections of stainless steel pipe. Thus, the first driving member drives the welding gun to move towards the base and abut against the stainless steel pipe to be welded. Simultaneously, with the cooperation of the driving mechanism, the stainless steel pipe rotates. After the two sections of stainless steel pipe have rotated one revolution, the welding operation on the two sections of stainless steel pipe is completed.

[0012] As a further improvement to the above technical solution, it also includes: two support mechanisms and a driving mechanism, wherein the driving end of the driving mechanism is connected to the support mechanism and the driving mechanism is connected to the base; the two support mechanisms are respectively used to support two sections of stainless steel pipe; the driving mechanism is used to simultaneously drive the two support mechanisms to rotate so that the two sections of stainless steel pipe rotate synchronously; when the first protective block and the second protective block are in a closed state, the two support mechanisms and the driving mechanism are all located in the sealed space formed by the first protective block and the second protective block.

[0013] As a further improvement to the above technical solution: the support mechanism includes a support tube, two first support blocks, and two adjusting rods. Both first support blocks are located inside the support tube and are arranged opposite to each other. The adjusting rods pass through the support tube and are threadedly connected to it. One end of the adjusting rod is rotatably connected to a first support block. Thus, the stainless steel tube is clamped by the two first support blocks to fix it, ensuring that the stainless steel tube does not move relative to the support tube, thereby improving the welding effect of the stainless steel tube. Furthermore, the spacing between the two first support blocks can be adjusted using the adjusting rods to accommodate stainless steel tubes of different sizes.

[0014] As a further improvement to the above technical solution: the driving mechanism includes a second driving member, two first gears, two second gears, and a rotating rod. The second driving member is connected to the base. The two first gears are respectively sleeved on the two support tubes. The two second gears mesh with the two first gears respectively. Both second gears are connected to the rotating rod. The driving end of the second driving member is connected to the rotating rod. Therefore, activating the second driving member drives the rotating rod to rotate, causing the two second gears to rotate synchronously, which in turn causes the two first gears to rotate synchronously, the two support tubes to rotate synchronously, and ultimately the two stainless steel pipes to rotate synchronously. This further improves the welding effect of the two stainless steel pipes.

[0015] As a further improvement to the above technical solution, it also includes: a second support block and a third support block. The third support block is located on the side of the second support block away from the support mechanism. Both the second and third support blocks are connected to the base. The second support block is rotatably connected to the support tube, and the third support block is used to support the stainless steel tube. When the first and second protective blocks are in a closed state, the second support block is located within the sealed space formed by the first and second protective blocks, and the third support block is located outside the sealed space formed by the first and second protective blocks. Thus, by supporting the support tube with the second support block and supporting the non-welded end of the stainless steel tube with the third support block, it is ensured that the stainless steel tube will not tilt and will always remain horizontal. The two sections of stainless steel tube can be completely aligned without gaps, thereby further improving the welding effect of the two sections of stainless steel tube.

[0016] As a further improvement to the above technical solution, it also includes: a top plate, which is located above the welding mechanism, the welding mechanism is connected to the top plate, and the top plate is connected to the base through a support rod.

[0017] The beneficial effects of this utility model are as follows:

[0018] During the welding process of two stainless steel pipes, the operator is protected by a first and second protective block in a closed state. Compared with the existing welding method without protective measures, this method has a simple structure and is easy to operate. The two stainless steel pipes are placed in the sealed space of the first and second protective blocks for welding, which can avoid the strong arc light generated during the welding process from causing damage to the operator's eyes and skin, and can also avoid the high temperature spatter generated during the welding process from burning the operator. In this way, the operator can effectively protect the operator and improve the safety of stainless steel pipe welding operations. In addition, the operator can also observe the progress of the welding operation of the two stainless steel pipes in real time through the transparent protective plate.

[0019] This utility model also has the following advantages:

[0020] 1. This utility model, through the cooperation of the connecting block and the snap-fit ​​block, can realize the opening and closing of the first protective block and the second protective block. When the connecting block and the snap-fit ​​block are connected, the first protective block and the second protective block cannot rotate relative to the base due to the restraint of the connecting block and the snap-fit ​​block. In this way, it can ensure that the two stainless steel pipes are in a closed space for welding operations.

[0021] 2. In the process of welding two stainless steel pipes, the present invention uses an air purifier to purify the toxic and harmful gases generated during the welding process. The purified gas is then pumped out to avoid the direct discharge of toxic and harmful gases and pollution of the environment. Attached Figure Description

[0047] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0048] like Figures 1 to 8 The diagram shows the preferred embodiment of this utility model. The welding device for stainless steel pipes in this embodiment includes: a base 1, a welding mechanism 2, and a protective mechanism 3. The welding mechanism 2 is located above the base 1 and is used for welding two sections of stainless steel pipes. The protective mechanism 3 includes: a first protective block 301 and a second protective block 302. Both the first protective block 301 and the second protective block 302 are hollow structures and are rotatably connected to the base 1. A transparent protective plate 303 is provided on the side of the first protective block 301 away from the second protective block 302. When the first protective block 301 and the second protective block 302 are in a closed state, the welding mechanism 2 and the welding point of the two sections of stainless steel pipes are located in the sealed space formed by the first protective block 301 and the second protective block 302. Therefore, during the welding process of the two stainless steel pipes, the first protective block 301 and the second protective block 302, which are in a closed state, protect the operator. Compared with the existing welding method without protective measures, this method has a simple structure and is easy to operate. By placing the two stainless steel pipes in the sealed space of the first protective block 301 and the second protective block 302 for welding, it is possible to avoid the strong arc light generated during the welding process from causing damage to the operator's eyes and skin, and it is also possible to avoid the high-temperature spatter generated during the welding process from burning the operator. In this way, the operator can be effectively protected to improve the safety of stainless steel pipe welding operations. In addition, the operator can also observe the progress of the welding operation of the two stainless steel pipes in real time through the transparent protective plate 303.

[0049] In this embodiment, it further includes: a connecting mechanism 4, the two ends of which are respectively mounted on the first protective block 301 and the second protective block 302; when the connecting mechanism 4 is in the open state, the first protective block 301 and the second protective block 302 can rotate relative to the base 1; when the connecting mechanism 4 is in the closed state, the first protective block 301 and the second protective block 302 cannot rotate relative to the base 1, and the first protective block 301 and the second protective block 302 are in the closed state; the connecting mechanism 4 includes: a connecting block 401 and a snap-fit ​​block 402, the connecting block 401 is connected to the first protective block 301, the snap-fit ​​block 402 is connected to the second protective block 302, and the connecting block 401 and the snap-fit ​​block 402 are connected. Therefore, through the cooperation of the connecting block 401 and the snap-fit ​​block 402, the first protective block 301 and the second protective block 302 can be opened and closed. When the connecting block 401 and the snap-fit ​​block 402 are connected, the first protective block 301 and the second protective block 302 cannot rotate relative to the base 1 due to the restraint of the connecting block 401 and the snap-fit ​​block 402. In this way, it can be ensured that the two stainless steel pipes are in a closed space for welding operations.

[0050] In this embodiment, a filtration mechanism 5 is also included. The filtration mechanism 5 includes an air purifier 501 and a pump 502. The inlet end of the air purifier 501 is connected to the sealed space formed by the first protective block 301 and the second protective block 302, and the outlet end of the air purifier 501 is connected to the pump 502. Both the air purifier 501 and the pump 502 are installed on the side wall of the first protective block 301. Thus, during the welding process of the two stainless steel pipes, the air purifier 501 can purify the toxic and harmful gases generated during the welding process. The purified gas is then extracted by the pump 502 to prevent the direct discharge of toxic and harmful gases and environmental pollution.

[0051] In this embodiment, the welding mechanism 2 includes a first driving member 201 and a welding gun 202. The welding gun 202 is mounted on the telescopic end of the first driving member 201. The first driving member 201 drives the welding gun 202 to move up and down, so that the welding gun 202 moves towards or away from the base 1. The welding gun 202 is used to perform welding operations on two sections of stainless steel pipe. Thus, the first driving member 201 drives the welding gun 202 to move towards the base 1 and abut against the stainless steel pipe to be welded. At the same time, with the cooperation of the driving mechanism 7, the stainless steel pipe rotates. After the two sections of stainless steel pipe have rotated one revolution, the welding operation of the two sections of stainless steel pipe is completed.

[0052] For example, the first driving component 201 is a cylinder.

[0053] In this embodiment, it further includes: two support mechanisms 6 and a driving mechanism 7. The driving end of the driving mechanism 7 is connected to the support mechanism 6, and the driving mechanism 7 is connected to the base 1. The two support mechanisms 6 are used to support two sections of stainless steel pipe, and the driving mechanism 7 is used to drive the two support mechanisms 6 to rotate simultaneously, so that the two sections of stainless steel pipe rotate synchronously. When the first protective block 301 and the second protective block 302 are in the closed state, the two support mechanisms 6 and the driving mechanism 7 are all located in the sealed space formed by the first protective block 301 and the second protective block 302. The support mechanism 6 includes: a support pipe 601, two first support blocks 602, and two adjusting rods 603. Both 2 are located inside the support tube 601, and the two first support blocks 602 are arranged opposite to each other. The adjusting rod 603 passes through the support tube 601 and is threadedly connected to the support tube 601. One end of the adjusting rod 603 is rotatably connected to the first support block 602. The driving mechanism 7 includes: a second driving member 701, two first gears 702, two second gears 703 and a rotating rod 704. The second driving member 701 is connected to the base 1. The two first gears 702 are respectively sleeved on the two support tubes 601. The two second gears 703 are respectively meshed with the two first gears 702. Both second gears 703 are connected to the rotating rod 704. The driving end of the second driving member 701 is connected to the rotating rod 704. Therefore, the stainless steel pipe is clamped by the two first support blocks 602 to fix it and ensure that the stainless steel pipe does not move relative to the support pipe 601, thus improving the welding effect of the stainless steel pipe. In addition, the distance between the two first support blocks 602 can be adjusted by the adjusting rod 603 to accommodate stainless steel pipes of different sizes. The second driving component 701 is activated, which drives the rotating rod 704 to rotate, so that the two second gears 703 rotate synchronously, which in turn causes the two first gears 702 to rotate synchronously, and the two support pipes 601 to rotate synchronously. Finally, the two stainless steel pipes rotate synchronously, which further improves the welding effect of the two stainless steel pipes.

[0054] For example, the second drive unit 701 uses a motor.

[0055] In this embodiment, the system further includes a second support block 8 and a third support block 9. The third support block 9 is located on the side of the second support block 8 away from the support mechanism 6. Both the second support block 8 and the third support block 9 are connected to the base 1. The second support block 8 is rotatably connected to the support tube 601, and the third support block 9 is used to support the stainless steel tube. When the first protective block 301 and the second protective block 302 are in a closed state, the second support block 8 is located within the sealed space formed by the first protective block 301 and the second protective block 302, and the third support block 9 is located outside the sealed space formed by the first protective block 301 and the second protective block 302. Thus, the second support block 8 supports the support tube 601, and the third support block 9 supports the non-welded end of the stainless steel tube, ensuring that the stainless steel tube will not tilt and will always remain horizontal. The two sections of stainless steel tube can be completely aligned without gaps, thereby further improving the welding effect of the two sections of stainless steel tube.

[0056] In this embodiment, it also includes: a top plate 10, which is located above the welding mechanism 2. The welding mechanism 2 is connected to the top plate 10, and the top plate 10 is connected to the base 1 through a support rod 11.

[0057] The welding process of the two stainless steel pipes of this utility model is as follows: First, the two stainless steel pipes are inserted into the two support pipes 601 respectively, and the adjusting rod 603 is rotated so that the two first support blocks 602 clamp and fix the stainless steel pipes together. The stainless steel pipes are supported by the first support block 602, the second support block 8, and the third support block 9 (at this time, the first protective block 301 and the second protective block 302 are in the open state); Next, the first driving component 201 is activated, which drives the welding gun 202 to move closer to the stainless steel pipe so that the welding gun 202 abuts against the stainless steel pipe to be welded; Then, the first protective block 301 and the second protective block 302 are rotated, and the first protective block 301 and the second protective block 302 are fixed by the connecting block 401 and the snap-fit ​​block 402 so that the first protective block 301 and the second protective block 302 are fixed together. Block 302 is in the closed state; finally, the welding gun 202, the second drive unit 701, the air purifier 501, and the pump 502 are started. The second drive unit 701 drives the rotating rod 704 to rotate, and with the cooperation of the first gear 702 and the second gear 703, the two stainless steel pipes rotate 360° synchronously. The welding process is protected by the first protective block 301 and the second protective block 302. The welding process of the two stainless steel pipes can be observed in real time through the transparent protective plate 303. The welding gun 202 is used for welding operations. The toxic and harmful gases generated during the welding process are purified by the air purifier 501 and then discharged by the pump 502. After the two stainless steel pipes are welded, the binding between the connecting block 401 and the locking block 402 is released, so that the first protective block 301 and the second protective block 302 can be opened, and the welded stainless steel pipes can be taken out.

[0058] In summary, this invention protects operators during the welding of two stainless steel pipe sections by using a first protective block 301 and a second protective block 302 in a closed state. Compared to existing welding methods without protective measures, this method is simple in structure and easy to operate. By placing the two stainless steel pipe sections within the sealed space of the first protective block 301 and the second protective block 302 for welding, it can prevent the intense arc light generated during welding from causing damage to the operator's eyes and skin, and it can also prevent the high-temperature spatter from burning the operator. Thus, it can effectively protect the operator and improve the safety of stainless steel pipe welding operations. In addition, the operator can also observe the progress of the welding operation of the two stainless steel pipe sections in real time through the transparent protective plate 303.
