Description

Technical Field

[0001] This utility model belongs to the field of semi-automatic magnetic cutting technology, and specifically relates to an auxiliary device for beveling small-diameter pipes. Background Technology

[0002] In the field of steel structure construction, steel pipes, as one of the basic materials, are widely used in various building structures. To meet the requirements of welding processes, especially full penetration welding, precise beveling of the steel pipe edges is necessary. However, for smaller diameter steel pipes (such as 2-inch or 3-inch pipes), most semi-automatic magnetic cutting machines on the market, due to their design limitations, can only handle steel pipes with a minimum diameter of 4 inches. This results in a large number of small-diameter steel pipes not being able to undergo efficient and precise beveling using automated equipment. The traditional method relies on workers manually completing this task with handheld welding torches. This method is not only inefficient but also prone to inconsistent product quality, increasing the difficulty of subsequent welding processes. Especially in large-scale production environments, this inefficient manual operation has become a key bottleneck restricting the improvement of production efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an auxiliary device for beveling small diameter pipes. This device can be fitted over the small diameter pipe and fix the small pipe. The clamping part of the semi-automatic magnetic cutter is then placed on this auxiliary device, thereby realizing the automatic beveling and cutting operation of small diameter pipes.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: an auxiliary device for beveling small-diameter pipes, comprising: an outer sleeve and multiple bolts, the outer sleeve having a first opening and a second opening, the diameters of the first opening and the second opening being equal, the outer sleeve having a cylindrical body, the cylindrical body being connected to the first opening and the second opening, the cylindrical body having threaded holes, the threaded holes including a first threaded hole and a second threaded hole, the bolts being screwed into the threads; the outer sleeve is used to fit over the outside of the small-diameter pipe, the distance between the first threaded hole and the second threaded hole being greater than or equal to the distance between the threaded hole and the end face of the small-diameter pipe.

[0005] Compared to existing technologies, the advantages of this invention are as follows: By using a specially designed sleeve and several bolts, the small-diameter pipe is effectively fixed, ensuring stability during the cutting process. Furthermore, the radially distributed threaded holes and bolts on the sleeve allow for convenient adjustment and fixation of the small-diameter pipe's position. This ensures the small-diameter pipe remains stable during cutting, guaranteeing consistent and precise cutting quality. Simultaneously, by rationally setting the distance between the threaded holes and their distance from the end face of the small-diameter pipe, the welding torch head accurately contacts and processes the pipe's surface during cutting, improving cutting quality and work efficiency. This invention, through the aforementioned device, successfully expands the application scope of semi-automatic magnetic cutting machines to the beveling and cutting of small-diameter pipes, effectively replacing traditional manual operation. This not only reduces the labor intensity of workers but also significantly improves production efficiency, reduces errors caused by manual operation, and enhances the overall quality of the product.

[0007] The aforementioned auxiliary device, a semi-automatic magnetic cutting machine, can be snapped into the outer sleeve, and the semi-automatic magnetic cutting machine is located between the first threaded hole and the second threaded hole.

[0008] In the aforementioned auxiliary device, the radius difference between the outer sleeve and the small-diameter tube is less than the length of the welding torch head of the semi-automatic magnetic cutting machine.

[0009] In the aforementioned auxiliary device, the length of the bolt's thread is greater than or equal to the radius difference between the outer sleeve and the small-diameter pipe.

[0010] With the aforementioned auxiliary device, after the small-diameter tube is fixed to the outer sleeve, the welding torch head of the semi-automatic magnetic cutting machine can fit against the outer wall of the small-diameter tube.

[0017] Explanation of reference numerals: 100 outer sleeve, 200 bolt, 110 first opening, 120 second opening, 130 cylinder, 131 first threaded hole, 132 second threaded hole, 300 semi-automatic magnetic cutting machine, 310 clamping part of semi-automatic magnetic cutting machine, 320 welding torch head of semi-automatic magnetic cutting machine, 400 small diameter pipe. Detailed Implementation

[0018] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 2 An embodiment of this utility model provides an auxiliary device for beveling a small-diameter pipe, comprising: an outer sleeve 100 and a plurality of bolts 200. The outer sleeve 100 has a first opening 110 and a second opening 120, the diameters of the first opening 110 and the second opening 120 being equal. The outer sleeve 100 has a cylindrical body 130, which is connected to the first opening 110 and the second opening 120. The cylindrical body 130 is provided with threaded holes, including a first threaded hole 131 and a second threaded hole 132. The bolts 200 can be screwed into the threads. The outer sleeve 100 is used to fit over the outside of a small-diameter pipe 400. The distance between the first threaded hole 131 and the second threaded hole 132 is greater than or equal to the distance between the threaded hole and the end face of the small-diameter pipe 400. By using a specially designed sleeve 100 and several bolts 200, the small-diameter pipe 400 is effectively fixed, ensuring stability during the cutting process. Furthermore, the radially distributed threaded holes on the sleeve 100 and the bolts 200 allow for convenient adjustment and fixation of the small-diameter pipe 400's position. This ensures the small-diameter pipe 400 remains stable during cutting, guaranteeing consistent and precise cutting quality. Simultaneously, by rationally setting the distance between the threaded holes and their distance from the end face of the small-diameter pipe 400, the welding torch head 320 accurately contacts and processes the surface of the small-diameter pipe 400 during cutting, improving cutting quality and work efficiency. This invention, through the aforementioned device, successfully expands the application scope of the semi-automatic magnetic cutting machine 300 to the cutting and beveling of small-diameter pipes 400, effectively replacing traditional manual operation. This not only reduces the labor intensity of workers but also significantly improves production efficiency, reduces errors caused by manual operation, and enhances the overall quality of the product.

[0019] Furthermore, this application does not limit the specific location of the threaded holes. Preferably, the threaded holes are located on one side of the first opening 110 and the second opening 120. More specifically, this application proposes that the first threaded hole 131 is located on one side of the first opening 110, and the second threaded hole 132 is located on one side of the second opening 120. The number of threaded holes 131 and 132 must be no less than two, and the two first threaded holes 131 are arranged vertically. By providing threaded holes on both sides of the first opening 110 and the second opening 120, multi-point fixation of the small-diameter tube 400 can be achieved. This design significantly improves the stability of the fixing structure, preventing the small-diameter tube 400 from shifting or rotating during the cutting process, thereby ensuring the accuracy of the cutting operation. The vertical arrangement of the two first threaded holes 131 helps to evenly distribute the clamping force, avoiding deformation or damage to the small-diameter tube 400 due to excessive force at a single point. The vertical arrangement of the threaded holes distributes the fixing stress more evenly, allowing the small-diameter pipe 400 to maintain its original shape throughout the fixing process, ensuring high-quality bevel cutting. The presence of multiple threaded holes allows for the selection of different fixing points according to actual needs, providing greater operational flexibility. For example, when dealing with small-diameter pipes 400 of different sizes or shapes, the most suitable combination of threaded holes can be selected for fixing to achieve the best fixing effect. This not only improves the versatility of the equipment but also simplifies the operation process and reduces preparation time. Furthermore, the semi-automatic magnetic cutter 300 can be snapped onto the outer sleeve 100, and the semi-automatic magnetic cutter 300 is located between the first threaded hole 131 and the second threaded hole 132. This design greatly enhances the flexibility and adaptability of the equipment. Specifically, it allows the operator to adjust the cutting position according to actual needs without changing the entire structure of the device or reinstalling the equipment. This not only simplifies the operation process and reduces preparation time but also significantly improves production efficiency. In addition, since the cutter is located between two fixing points, the stability during the cutting process is further enhanced, ensuring high-quality, consistent bevel cutting results. Of course, this utility model does not limit the specific position of the semi-automatic magnetic cutting machine 300 on the outer sleeve 100. Preferably, referring to... Figure 2The clamping part 310 of the semi-automatic magnetic cutting machine is located at the center of the first threaded hole 131 and the second threaded hole 132. Furthermore, this application does not limit the specific dimensions of the outer sleeve 100. Preferably, the diameter of the outer sleeve 100 is determined according to the diameter range of the clamping part 310 of the semi-automatic magnetic cutting machine. This customized design ensures a perfect match between the sleeve 100 and the cutting machine. A suitable diameter not only facilitates the installation and disassembly of the cutting machine but also maximizes its performance advantages and improves cutting efficiency. In addition, the ability to adjust the diameter of the sleeve 100 according to specific needs makes the device suitable for various specifications of semi-automatic magnetic cutting machines 300, enhancing its versatility and market competitiveness. This flexibility and compatibility saves enterprises the cost of purchasing new equipment while also improving the overall efficiency of the production line. Furthermore, the radius difference between the outer sleeve 100 and the small-diameter pipe 400 is less than the length of the welding torch head 320 of the semi-automatic magnetic cutting machine. The radius difference between the outer sleeve 100 and the small-diameter pipe 400 is less than the length of the welding torch head 320 of the semi-automatic magnetic cutting machine. This ensures that the welding torch head 320 can cut the small-diameter pipe 400 tightly against its outer wall without damaging the sleeve. This design avoids inaccurate cutting caused by an excessively long welding torch head, and also prevents unnecessary collisions or friction between the welding torch head 320 and the sleeve, extending the service life of the equipment. More importantly, this precise fit helps improve cutting accuracy, reduce material waste, and enhance the quality of the final product. Of course, this application does not limit the specific length of the welding torch head 320 of the semi-automatic magnetic cutting machine. Preferably, the length of the welding torch head 320 of the semi-automatic magnetic cutting machine is adjustable.

[0020] Furthermore, the length of the bolt 200 is greater than or equal to the radius difference between the outer sleeve 100 and the small-diameter pipe 400. This design ensures that the bolt 200 can effectively pass through the sleeve 100 and securely fix the small-diameter pipe 400. Sufficient bolt length not only provides the necessary clamping force but also accommodates small-diameter pipes 400 of varying thicknesses, increasing the versatility and flexibility of the device. In this way, regardless of the specific dimensions of the small-diameter pipe 400, it can be safely and reliably fixed inside the sleeve 100, laying a solid foundation for subsequent automated cutting operations. Further, the small-diameter pipe 400 is fixed to the outer sleeve 100 using multiple bolts 200. This fixing method is not only simple but also effective; the multi-point fixing strategy not only enhances the overall structural stability but also disperses fixing stress, reducing the risk of localized deformation. Simultaneously, this design allows for quick loading and unloading of the small-diameter pipe 400, significantly shortening preparation time and improving work efficiency. In addition, since each bolt 200 can be independently adjusted, the fixing force can be flexibly adjusted according to actual conditions to ensure optimal fixing results, guaranteeing high-quality bevel cutting. Furthermore, after the small-diameter pipe 400 is fixed to the outer sleeve 100, the welding torch head 320 of the semi-automatic magnetic cutting machine can fit against the outer wall of the small-diameter pipe 400. When the small-diameter pipe 400 is fixed to the outer sleeve 100, the welding torch head 320 of the semi-automatic magnetic cutting machine can fit against the outer wall of the small-diameter pipe 400, which means that the cutting process can be performed more smoothly and precisely. The close fit between the welding torch head 320 and the pipe reduces vibration and displacement during cutting, thereby improving cutting quality. In addition, this design allows the operator to more precisely control the cutting depth and angle, ensuring that each cut achieves the expected results. This is particularly important for small-diameter pipe fittings that require high-precision machining, significantly improving product yield and consistency.

[0021] Furthermore, the welding torch head 320 of the semi-automatic magnetic cutting machine can rotate around the outer sleeve 100. This is key to achieving automated and efficient cutting. Through this rotation mechanism, the welding torch head 320 can complete omnidirectional cutting tasks without moving the small-diameter tube 400, greatly simplifying the operation process. The rotation function not only improves cutting efficiency but also reduces the need for manual intervention and lowers labor intensity. Of course, this application does not limit the rotation method of the welding torch head 320; it can be that the outer sleeve 100 is fixed and the welding torch head 320 rotates around the outer sleeve 100, or it can be that the welding torch head 320 is fixed and the outer sleeve 100 rotates around the welding torch head 320 under the action of the clamping tool. Furthermore, the outer sleeve 100 is made of high-strength steel. The choice of high-strength steel for the outer sleeve 100 gives the sleeve excellent mechanical properties and durability. High-strength steel not only has good compressive and tensile strength but also excellent wear resistance and corrosion resistance, enabling it to withstand long-term, high-intensity use without easy damage. The choice of this material significantly extends the service life of the sleeve 100 and reduces maintenance costs. Furthermore, the use of high-strength steel ensures that the sleeve 100 is not easily deformed during operation, providing a solid support foundation for high-quality cutting operations. Of course, this application does not limit the specific forming method of the outer sleeve 100; preferably, the outer sleeve 100 can be integrally formed. An integrally formed sleeve 100 has no welding points or other connecting parts, thus possessing higher structural integrity and strength, and is less prone to cracks or breakage. In addition, integral forming can also ensure the consistency and symmetry of all parts of the sleeve 100, which is crucial for ensuring stability and accuracy during the cutting process.
