Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically to a stainless steel pipe weld treatment device. Background Technology

[0002] Stainless steel pipe is a type of pipe with excellent corrosion resistance, high strength, and good appearance. It is usually composed of alloying elements such as iron, chromium, and nickel. Its corrosion resistance allows it to remain stable in various harsh environments, not easily rusting or corroding, and it is widely used in many fields such as construction, chemical industry, food, and medical industry. According to its structure, it can be divided into seamless steel pipe and welded steel pipe; according to its surface treatment, it can be divided into polished pipe and brushed pipe, etc. Welding is an important process for joining stainless steel pipes together. Due to the special properties of stainless steel, specialized welding processes and materials are required for welding. Commonly used welding methods include tungsten inert gas welding (TIG) and gas metal arc welding (GMAW). These methods can effectively protect the weld area, prevent oxidation, and ensure weld quality. During the welding process, welding parameters, such as current, voltage, and welding speed, must be strictly controlled to avoid defects such as overheating, deformation, and cracking. Furthermore, welding requires highly skilled welders who need professional training to ensure that the quality and performance of the welded joint meet the requirements, enabling the welded stainless steel pipe to meet the needs of different application scenarios.

[0003] A search revealed that Chinese Patent Publication No. CN221185867U discloses a stainless steel pipe weld treatment device, which includes a stainless steel pipe driving unit, a mounting base plate, and multiple grinding units. Each grinding unit includes a mounting rod, a passive pulley, a grinding wheel frame, a grinding wheel, and a first rotating shaft. An upper limit plate and a lower limit plate are fixed to the mounting rod, and a locking bolt is provided at the lower limit plate. An active pulley is provided at the mounting base plate, and the passive pulley can drive the first rotating shaft. An active bevel gear is provided at the bottom end of the first rotating shaft, and a driven bevel gear is provided at the grinding wheel.

[0004] However, this device also has the following drawbacks:

[0005] When butt welding two sets of stainless steel pipes, a circumferential weld will be left at the weld joint. However, the device can only grind the weld from one direction, making it difficult to grind the circumferential weld in one go, resulting in low processing efficiency. The device has not solved this problem. Utility Model Content

[0006] The purpose of this invention is to provide a device for treating weld seams in stainless steel pipes.

[0007] The technical problem solved by this utility model is that the existing technology makes it difficult to grind the circumferential weld in one go, resulting in low processing efficiency.

[0008] This utility model can be achieved through the following technical solutions:

One end of the spring abuts against one side of the fixed seat, and the other end of the spring abuts against the mounting bracket.

[0011] It also includes a sliding assembly, which includes two sets of symmetrically arranged arc-shaped seats. The arc-shaped seats abut against the lower surface of the stainless steel tube body, and a slide seat is fixedly installed at the bottom of the arc-shaped seats. The slide seat is slidably installed on the surface of the guide rod.

[0015] Preferably, the sliding component is disposed on the other side of the grinding component, and the sliding component further includes a connecting rod, the two ends of which are fixedly connected to two sets of arc-shaped seats respectively.

[0016] Preferably, both ends of the guide rod are fixedly installed on the mounting plate, and the bottom of the mounting plate is fixedly installed on the top of the processing table.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0028] A stainless steel pipe weld treatment device includes a grinding assembly, which includes a drive roller 1 and a driven roller 2. A grinding belt 3 is sleeved on the outer side of the drive roller 1 and the driven roller 2. The drive roller 1 and the driven roller 2 are connected by a transmission through the grinding belt 3. The drive roller 1 is rotatably mounted on the inner side of the mounting frame 5, and the driven roller 2 is rotatably mounted on the outer side of the mounting frame 5. The top of the drive roller 1 is driven by the output end of the motor 12, and the motor 12 is fixedly mounted on the top of the mounting frame 5.

[0029] By setting up motor 12, the output end of motor 12 can drive the active roller 1 to rotate. Since the active roller 1 and the driven roller 2 are sleeved with a grinding belt 3, and the two are connected by the transmission of the grinding belt 3, the rotation of the active roller 1 will cause the grinding belt 3 to rotate around the active roller 1 and the driven roller 2 in a cycle, so that the grinding particles on the surface of the grinding belt 3 will continuously grind the weld of the stainless steel pipe.

[0030] It also includes an elastic component, which is located on one side of the grinding component. The elastic component includes two sets of slide rods 4. One end of the slide rod 4 is fixedly mounted with a mounting bracket 5. The slide rod 4 is slidably engaged with the fixed seat 6. A spring 7 is slidably sleeved on the surface of the slide rod 4. One end of the spring 7 abuts against one side of the fixed seat 6, and the other end of the spring 7 abuts against the mounting bracket 5. A limit plate 13 is fixedly mounted on the other end of the slide rod 4. The limit plate 13 is located on the other side of the fixed seat 6. The fixed seat 6 is fixedly connected to the top surface of the processing table 14.

[0031] By setting up the slide bar 4 and spring 7, when the stainless steel tube body 9 approaches the grinding assembly for grinding, the stainless steel tube exerts pressure on the grinding assembly. Under the pressure, the mounting bracket 5 slides along the slide bar 4 towards the fixed seat 6. At this time, the spring 7 is compressed, and the spring 7 generates a reverse elastic force. This elastic force interacts with the pressure of the stainless steel tube body 9 on the grinding assembly, keeping the contact pressure between the two within a suitable range. When the pressure decreases or is removed, the elastic force of the spring 7 will cause the mounting bracket 5 to return to its original position along the slide bar 4. By setting up the elastic component, excessive pressure can be effectively prevented when the stainless steel tube body 9 contacts the grinding assembly. If the pressure is too high, it may cause excessive wear or even damage to the grinding belt 3, and may also cause excessive grinding or damage to the surface of the stainless steel tube. Through the elastic action of the spring 7, the service life of the grinding belt 3 can be extended, and the stability and consistency of the grinding effect can be guaranteed.

[0032] It also includes a sliding assembly, which includes two sets of symmetrically arranged arc-shaped seats 8. The arc-shaped seats 8 abut against the lower surface of the stainless steel tube body 9. A slide seat 10 is fixedly installed at the bottom of the arc-shaped seats 8. The slide seat 10 is slidably installed on the surface of the guide rod 11. The sliding assembly is located on the other side of the grinding assembly. The sliding assembly also includes a connecting rod 15. The two ends of the connecting rod 15 are fixedly connected to the two sets of arc-shaped seats 8 respectively. The two ends of the guide rod 11 are fixedly installed on the mounting plate 16. The bottom of the mounting plate 16 is fixedly installed on the top of the processing table 14.

[0033] By setting up the arc-shaped seat 8, the stainless steel tube body 9 can be supported. When it is necessary to move the stainless steel tube body 9 closer to the grinding assembly, the arc-shaped seat 8 can be pushed. Since the slide seat 10 at the bottom of the arc-shaped seat 8 is slidably installed on the surface of the guide rod 11, the arc-shaped seat 8 will slide along the guide rod 11, thereby moving the stainless steel tube body 9 closer to the grinding assembly. When it is necessary to adjust the position of the stainless steel tube body 9, such as rotating the stainless steel tube body 9 to grind different positions of the circumferential weld, the stainless steel tube body 9 can also be moved away from the grinding assembly by sliding the arc-shaped seat 8, and then moved back to the grinding assembly after adjusting the position. As grinding continues near the grinding assembly, the arc-shaped seat 8 is designed to fit well against the lower surface of the stainless steel tube body 9, providing stable support. During grinding, the stainless steel tube body 9 can be manually pressed against the arc-shaped seat 8, which can improve the grinding accuracy. At the same time, the position of the stainless steel tube body 9 can be easily adjusted through the cooperation of the slide 10 and the guide rod 11, making it easy to align the annular weld seam with the grinding assembly for grinding, which greatly improves the processing efficiency. Moreover, the connecting rod 15 fixes the two sets of arc-shaped seats 8 together, ensuring the synchronization and stability of the two during the sliding process.

[0034] In use, the device is moved to the designated position, the stainless steel tube body 9 to be processed is placed on the arc-shaped seat 8, the slide 10 is pushed along the guide rod 11 to bring the stainless steel tube close to the grinding assembly, the motor 12 is started to make the active roller 1 drive the grinding belt 3 to rotate, the stainless steel tube body 9 is manually pressed against the arc-shaped seat 8 to ensure stability, the stainless steel tube body 9 is slowly rotated during the grinding process, so that each part of the annular weld is ground in turn. During this process, the spring 7 of the elastic component will interact with the pressure to avoid damage to the grinding belt 3 and the stainless steel tube. If different welds need to be ground, the slide 10 can be pushed to move the stainless steel tube away from the grinding assembly for adjustment, and then brought closer to continue grinding. After all welds are ground, the motor 12 is turned off, the stainless steel tube body 9 is removed, and the processing work is completed.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
