Description

Technical Field

[0001] The present invention belongs to the technical field of deburring for double-layer pipelines, and particularly relates to a tool for deburring double-layer pipelines and a using method thereof. Background Art

[0002] The double-layer pipeline of the engine is mainly assembled by an inner layer pipe and an outer layer pipe. The main processing techniques are as follows: 1. Assembly: First, assemble the inner layer pipe and the outer layer pipe. The fitting clearance at both ends of the pipes is ensured to be coaxial inside and outside by inserting a positioning sleeve; 2. Bending: Bend the double-layer pipeline to form, and ensure that the non-coaxiality of the two pipes in the whole length is not greater than 1; 3. End removal: Mark the end-removal position according to the mold, and complete the end removal by manually sawing the pipe; 4. Deburring: Manually file and remove the burrs generated after the end removal of the pipe.

[0003] Since the end removal of the inner layer pipe and the outer layer pipe adopts fitter sawing, the forming quality of the pipe end surface after end removal is poor, large burrs are generated and the quantity is large. If the burrs are removed manually, due to the small gap between the inner layer pipe and the outer layer pipe, the burrs on the inner wall of the outer layer pipe are not easy to remove, and the outer wall of the inner layer pipe is easily damaged during the filing process. The surface quality of the pipe end directly affects the subsequent assembly and welding quality of the pipe assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide a tool for deburring double-layer pipelines and a using method thereof, so as to solve the problems that when removing burrs manually, due to the small gap between the inner layer pipe and the outer layer pipe, the burrs on the inner wall of the outer layer pipe are not easy to remove, and the outer wall of the inner layer pipe is easily damaged during the filing process.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a tool for deburring double-layer pipelines, including a sleeve and a cutting piece. The cutting piece is fixedly arranged at one end of the sleeve. The inner diameter of the sleeve matches the outer diameter of the inner layer pipe of the double-layer pipeline, and when the sleeve is sleeved on the inner layer pipe of the double-layer pipeline, the cutting piece can be in contact with the outer layer pipeline of the double-layer pipeline.

[0006] Further, the cutting piece is a hollow conical shape.

[0007] Further, the cutting piece includes a frustum of a cone and a cutting edge; a plurality of cutting edges are uniformly arranged on the conical surface of the frustum of a cone.

[0008] Further, a threaded connecting pipe is arranged at the end of the frustum of a cone, and internal threads are arranged on the inner side wall of the sleeve. The frustum of a cone is fixedly connected to the sleeve through the threaded connecting pipe.

[0009] Further, a connecting pipe is arranged at the end of the frustum of a cone. The connecting pipe is arranged inside the sleeve and is welded to the inner side wall of the sleeve.

[0010] Further, the cutting edge has a rectangular plate-like structure. One side of the rectangular plate-like structure is welded to the conical surface, and an inclined edge is provided on the other side.

[0011] Further, a handle is welded to the outer side of the sleeve.

[0012] Further, reinforcing ribs are provided at the welding joint of the handle and the sleeve.

[0013] Further, the handle is welded to one end of the outer side of the sleeve away from the cutting member.

[0014] In a second aspect, the present invention provides a method for using a tool for deburring double-layer pipelines, including the following steps: After the double-layer pipeline is bent, saw the pipe to complete the end removal; Insert the end of the sleeve with the cutting member into and sleeved on the inner pipeline of the double-layer pipeline, hold the handle and push the sleeve into the set position so that the cutting edge of the cutting member contacts the outer pipeline; Rotate the handle, and the cutting edge removes the burrs at the end and inside of the outer pipeline.

[0015] Compared with the prior art, the present invention has the following technical effects: Through the cooperation of the sleeve and the cutting member, the inner diameter of the sleeve matches the outer diameter of the inner pipeline of the double-layer pipeline, and it can be accurately sleeved on the inner pipeline, while the cutting member contacts the outer pipeline. During operation, insert the sleeve into the inner pipeline and rotate the handle to drive the cutting member to remove burrs, avoiding many drawbacks of manual filing, greatly improving the efficiency and quality of deburring, and laying a solid foundation for subsequent assembly and welding processes.

[0016] As the core component of this technical solution, the hollow conical cutting member not only has good structural stability but also can better adapt to the shape of the double-layer pipeline. The cutting member composed of a frustum of a cone and cutting edges evenly arranged on the conical surface can achieve efficient and uniform deburring effects. The cutting edge has a rectangular plate-like structure, one side is welded to the conical surface, and an inclined edge is provided on the other side. This design enables the cutting edge to cut into the burrs more sharply during rotation, improving the speed and effect of deburring. At the same time, the connection method between the frustum of a cone and the sleeve is diverse, and both threaded connection and welded connection can ensure the firmness of the connection, ensuring that the cutting member will not loosen during the deburring process. This structural design not only improves the service life of the tool but also ensures the stability and reliability of the deburring operation, enabling the operator to complete the work more easily and efficiently.

[0017] The usage method of the present invention fully considers the convenience and safety of operation. Hold the handle and push the sleeve into the set position, then rotate the handle to remove burrs. The operation is simple and easy to understand, and even inexperienced operators can quickly get started. The handle is welded to one end of the outer side of the sleeve away from the cutting part, which conforms to the ergonomic principle, and the operator can hold the handle more comfortably. The setting of the reinforcing rib further enhances the connection strength between the handle and the sleeve, improving the overall stability of the tool. By using this technical solution, the burrs at the end and inside of the outer layer tube can be completely removed, and the surface quality of the tube end is significantly improved. The high-quality tube end surface not only facilitates subsequent assembly and welding, but also improves the overall performance and service life of the tube assembly.

[0018] In summary, through the ingenious structural design and user-friendly usage method, the present invention effectively solves the problem of deburring double-layer pipelines, significantly improves the surface quality of the tube end, and makes an important contribution to the development of the double-layer pipeline processing industry.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] Example 1. Please refer to Figure 1 , the present invention provides a tool for deburring double-layer pipelines, including a sleeve 3 and a cutting piece. The cutting piece is fixedly arranged at one end of the sleeve 3. The inner diameter of the sleeve 3 matches the outer diameter of the inner layer pipe of the double-layer pipeline. When the sleeve 3 is sleeved on the inner layer pipe of the double-layer pipeline, the cutting piece can contact the outer layer pipeline of the double-layer pipeline.

[0027] The tool for deburring double-layer pipelines provided by the present invention shows remarkable technical effects in solving the practical problem of deburring double-layer pipelines, bringing many positive impacts to related processing fields.

[0028] The inner diameter of the sleeve 3 matches the outer diameter of the inner layer pipe of the double-layer pipeline. When it is sleeved on the inner layer pipe, positioning can be quickly and accurately achieved. This characteristic of precise adaptation enables operators to quickly install the tool in the correct position, greatly shortening the preparation time and improving work efficiency. At the same time, the stable positioning also provides a reliable guarantee for the subsequent contact between the cutting piece and the outer pipe, ensuring that the deburring operation can proceed smoothly.

[0029] The cutting piece is fixedly arranged at one end of the sleeve 3, and when the sleeve 3 is sleeved on the inner layer pipe of the double-layer pipeline, the cutting piece can contact the outer layer pipeline of the double-layer pipeline. The deburring action point is accurately positioned at the part of the outer layer pipeline that needs deburring. In traditional deburring methods, due to the lack of effective positioning and contact methods, it is very difficult to completely remove the burrs on the inner wall of the outer pipe. However, through the synergistic effect of the sleeve and the cutting piece of the tool of the present invention, the cutting piece can closely fit the inner wall of the outer pipe, and the burrs can be removed comprehensively and without dead angles during the rotation process. Whether it is the burrs on the end face of the pipeline or the burrs on the inner wall, they can be effectively cleaned under the action of the cutting piece, greatly improving the quality and effect of deburring.

[0030] The overall structure of this tool is simple and clear, consisting of two main components: a sleeve 3 and a cutting piece. This simple structural design not only reduces the manufacturing cost of the tool but also makes the operation more convenient and reliable. Operators do not need to undergo complex training. They only need to simply understand the usage method of the tool to easily get started. In actual operation, just slip the sleeve 3 over the inner layer pipe and then drive the cutting piece to rotate by rotating or other means to complete the deburring operation. At the same time, the simple structure also reduces the possibility of tool failure, improving the stability and durability of the tool. Even during high-intensity and long-term use, this tool can still maintain a good working state, providing reliable guarantee for the processing of double-layer pipelines.

[0031] During the deburring process of double-layer pipelines, it is crucial to protect the inner layer pipe from damage. The tool of the present invention completely isolates the cutting piece from the inner layer pipe through the isolation function of the sleeve 3, avoiding any damage to the inner layer pipe caused by the cutting piece during the deburring process. The sleeve 3 serves as a protective barrier for the inner layer pipe, capable of withstanding various forces and vibrations generated during the rotation of the cutting piece, ensuring that the inner layer pipe is always in a safe state.

[0032] Embodiment 2, the present invention provides a tool for deburring double-layer pipelines, specifically including: aiming to solve the problems of low efficiency and poor quality of traditional deburring methods. This tool mainly consists of a sleeve 3 and a cutting piece. The cutting piece is firmly arranged at one end of the sleeve 3. The inner diameter of the sleeve 3 is precisely matched with the outer diameter of the inner layer pipe of the double-layer pipeline. When the sleeve 3 is slipped over the inner layer pipe, the cutting piece can just come into contact with the outer pipeline.

[0033] The cutting piece is designed as a hollow conical shape. This shape not only gives it good structural stability but also better conforms to the complex shape of the double-layer pipeline. The cutting piece consists of a conical frustum and cutting edges 5 evenly distributed on the conical surface. The uniform arrangement of several cutting edges 5 ensures the high efficiency and uniformity of the deburring operation. Each cutting edge 5 is a rectangular plate-like structure, with one side welded to the conical surface and an inclined edge on the other side. This design enables the cutting edge to cut into the burrs more sharply during rotation, significantly improving the speed and effect of deburring. At the same time, the connection method between the conical frustum and the sleeve 3 is flexible. It can be fixedly connected through the threads of the threaded connecting pipe and the inner side wall of the sleeve 3, or the connecting pipe can be directly welded to the inner side of the sleeve 3. Both methods can ensure the firmness of the connection, ensuring that the cutting piece will not loosen during the deburring process.

[0034] To improve the convenience and safety of operation, a handle 4 is also welded to the outer side of the sleeve 3, and the handle 4 is welded to the outer side of the sleeve 3 at the end far from the cutting piece, enabling the operator to hold the handle more comfortably. In addition, a reinforcing rib 6 is provided at the welding joint of the handle 4 and the sleeve 3, further enhancing the connection strength between the handle and the sleeve and improving the overall stability of the tool.

[0035] The deburring tool for double-layer pipelines has a simple and ingenious structure, is convenient to use, has a low manufacturing cost. When deburring, the through hole of the tool can completely avoid the inner layer pipe and will not damage the outer wall of the inner layer pipe. The operator can quickly and accurately remove the burrs on the inner wall of the outer layer pipe. The deburring quality and efficiency of the pipe ends of the double-layer pipelines are significantly improved.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
