Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding ring processing technology, and in particular to a tooling for welding ring production. Background Technology
[0002] As an important welding material, welding rings play a key role in many application scenarios and fields, especially in situations where a high degree of sealing and stability is required.
[0003] In air conditioning systems, silencers are crucial components. Their function is to absorb or reduce noise generated by airflow through internal structural design, thereby lowering the overall noise level of the air conditioning system. Silencers in air conditioning systems are typically installed on refrigerant pipes to reduce noise generated by gas flow. Using welded rings to connect the silencer and refrigerant pipes is a common and effective practice. On one hand, welded rings provide a reliable seal, creating a very strong connection between the silencer and the pipe, effectively preventing refrigerant leakage. On the other hand, welded rings are suitable for pipes of different sizes, offering greater installation flexibility.
[0004] However, since the muffler is often connected to the refrigerant pipe via its side wall, and the side wall of the muffler has a curvature, directly welding the two together is very likely to result in air holes or leaks. To achieve a good welding effect, a method of first drilling and then enlarging the hole is usually used to create an opening in the side wall of the muffler, extending the opening slightly, and then welding it to the refrigerant pipe, thus achieving a better fixing effect.
[0005] The opening end produced using this processing technique will have an arc that matches the shape of the sidewall. To achieve better welding results and higher welding precision, a non-circular weld ring with a similar shape is required. However, due to its special shape, the existing weld ring production process typically requires manual bending of the produced circular weld rings into non-circular shapes. This processing method suffers from insufficient precision, making it prone to errors, and also has low processing efficiency, failing to meet the needs of mass production. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a tooling for the production of weld rings, which solves the problem of insufficient precision in manual processing of irregular weld rings, improves the low processing efficiency, and meets the needs of mass production.
[0007] To solve the above-mentioned technical problems, this utility model proposes a tooling for the production of welding rings, adopting the following technical solution:
[0008] A tooling for producing welding rings includes a first fixing member, a second fixing member, and a winding member. The winding member is cylindrical. The first fixing member and the second fixing member are respectively sleeved on both ends of the winding member. Both the first fixing member and the second fixing member are provided with slots. The slots are located on the same straight line and are parallel to the axis of the winding member. One end of the first fixing member sleeved on the winding member is designated as a first irregular end, and one end of the second fixing member sleeved on the winding member is designated as a second irregular end. The first irregular end and the second irregular end have the same shape and are parallel to each other near the edge of the winding member.
[0009] This structure allows the welding wire to be wound onto a winding component before further heating and shaping to produce the desired weld ring shape. Specifically, a first and second fixing member are installed at both ends of the winding component, and the ends closest to the winding component are designated as a first and second irregularly shaped end, respectively. These two irregularly shaped ends are designed to have the same shape as the side wall openings of the muffler. When the welding wire is wound onto the winding component, it can be tightened according to this shape before heating and shaping. Because both sides are designed with identical shapes and parallel edges, the welding wire is wound along this shape and tightly arranged on the winding component. After processing, a large number of interconnected irregularly shaped weld rings can be produced simultaneously. At this point, simply removing the second fixing member allows the weld ring to be detached from the winding component and then cut along the axial direction to obtain a large number of irregularly shaped weld rings. Compared to manual shaping of the weld rings, this method significantly improves production accuracy and efficiency, not only producing more accurate irregularly shaped weld rings but also enabling the production of large quantities of weld rings at once, meeting the needs of mass production. The slotted design on the first and second fixing parts facilitates a closer fit between the welding wire and the winding component. Because there is a height difference between the first and second fixing parts and the winding component, placing the end of the welding wire to be processed in the slot before tightening it onto the winding component allows the shape of the welding wire to better match the irregularly shaped end, thereby further improving the processing accuracy of the welding ring.
[0010] Furthermore, grooves are provided on the sidewalls of the winding component, penetrating the component and parallel to its axis, with the grooves and slots aligned on the same straight line. Since the welding wire is tightened and heat-shaped on the winding component, its removal may be difficult. Applying excessive tension could cause deformation of the already shaped wire, affecting the geometry of the finished product. To address this issue, grooves are designed on the winding component, allowing the welding wire to be cut along the grooves using a cutting tool after the heat-shaping process. This method not only allows the welding wire to be easily removed from the winding component but also ensures the accuracy of the shape of each weld ring through this trimming technique.
[0011] Preferably, the system also includes two fixing members, which are respectively fixedly connected to the ends of the first and second fixing members away from the winding member. The fixing members are cylindrical, with a diameter smaller than that of the first and second fixing members. The slots extend to the ends of the two fixing members closest to the first and second fixing members. The fixing members are designed to better secure the welding wire. When winding the welding wire, one end of the wire can be tightened onto the fixing member connected to the first fixing member first, and then the wire can be wound onto the winding member. Subsequently, the other end of the wire is tightened onto the fixing member on the other side. This prevents the end of the welding wire from loosening and falling off during subsequent processing, thus ensuring production quality.
[0012] Preferably, the axial length of the inner wall of the first irregular end is greater than the axial length of the outer wall, and a first inclined surface is formed between the inner and outer walls of the first irregular end. The shape of the first irregular end and the degree of fit between it and the welding wire greatly affect the production quality of the irregular welded ring. The design of the first inclined surface ensures that the welding wire fits the shape of the first irregular end better when passing through the connection between the slot and the first inclined surface. At the same time, the design of the inclined surface can increase the contact area, thereby providing greater friction and ensuring a more stable connection that is less prone to loosening.
[0013] Preferably, the axial length of the outer wall of the second irregular end is greater than the axial length of the inner wall, and a second inclined surface is formed between the inner and outer walls of the second irregular end. The inclination of the second inclined surface forms a fixing groove at the edge of the second irregular end. This design allows the welding wire to fit tightly against the edge when wound to this location, and provides a certain degree of fixing, thereby achieving better cooperation with the slot on the second fixing member.
[0014] Preferably, a limiting part is also included, which is fixedly connected to the fixing member. The radial dimension of the contact end between the limiting part and the fixing member is larger than the diameter of the fixing member. The design of the limiting part can further fix the position of the welding wire and prevent the welding wire wrapped on the fixing member from coming off. The two work together to achieve a better fixing effect.
[0015] In summary, this tooling for welding ring production solves the problem of insufficient precision in manual processing of irregularly shaped welding rings, improves processing efficiency, and meets the needs of mass production. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] In the description of this utility model, it should be understood that the orientation and positional relationship indicated by terms such as "up", "down", "left", "right", "front", "back", "vertical", "bottom", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] like Figures 1 to 3 The tooling shown includes a first fixing member 1, a second fixing member 2, and a winding member 3. The winding member 3 is cylindrical. The first fixing member 1 and the second fixing member 2 are respectively sleeved on both ends of the winding member 3. Both the first fixing member 1 and the second fixing member 2 are provided with slots 4. The slots 4 are located on the same straight line and are parallel to the axis of the winding member 3. One end of the first fixing member 1 sleeved on the winding member 3 is set as a first irregular end 11, and one end of the second fixing member 2 sleeved on the winding member 3 is set as a second irregular end 21. The first irregular end 11 and the second irregular end 21 have the same shape and are parallel to each other near the edge of the winding member 3.
[0025] Using this structure, the welding wire can be wound onto the winding member 3 and then subjected to a further heating and shaping process to produce the desired weld ring shape. Specifically, a first fixing member 1 and a second fixing member 2 are provided at both ends of the winding member 3, and the two ends closest to the winding member 3 are respectively designated as a first irregular end 11 and a second irregular end 21. The shapes of these two irregular ends are designed to be the same as the side wall openings of the muffler. Thus, when the welding wire is wound onto the winding member 3, it can be tightened according to this shape and then subjected to heating and shaping. Because both sides are designed with the same shape and parallel edges, after the welding wire is wound along this shape and tightly arranged on the winding member 3, a large number of irregularly shaped weld rings connected together can be produced simultaneously after processing. At this point, it is only necessary to remove the second fixing member 2 to remove the weld ring from the winding member 3, and then cut it along the axial direction to obtain a large number of irregularly shaped weld rings. This method significantly improves production accuracy and efficiency compared to manual shaping of the welding ring. It not only produces more accurately shaped irregular welding rings but also enables the production of large quantities at once, meeting the demands of mass production. The slotted design 4 on the first and second fixing members 1 and 2 facilitates a closer fit between the welding wire and the winding component 3. Because of the height difference between the first and second fixing members 1 and the winding component 3, placing the end of the welding wire to be processed in the slotted 4 before tightening it onto the winding component 3 ensures a better fit between the welding wire and the irregularly shaped end, further improving the processing accuracy of the welding ring.
[0026] Furthermore, a groove 31 is provided on the side wall of the winding component 3. The groove 31 penetrates the winding component 3 and is parallel to the axis of the winding component 3. The groove 31 and the slot 4 are located on the same straight line. Since the welding wire is tightened on the winding component 3 and undergoes a heating and shaping process, it may encounter some difficulties in removing itself from the winding component 3. If excessive tension is applied, the already shaped welding wire may deform, thereby affecting the geometry of the finished product. To solve this problem, by designing the groove 31 on the winding component 3, the welding wire can be cut along the groove 31 using a cutting tool after the heating and shaping process is completed. This method not only allows the welding wire to be easily removed from the winding component 3, but also ensures the accuracy of the shape of each welding ring through this trimming method.
[0027] Preferably, the system also includes two fixing members 5, which are fixedly connected to the ends of the first fixing member 1 and the second fixing member 2 away from the winding member 3, respectively. The fixing members 5 are cylindrical, and their diameters are smaller than those of the first fixing member 1 and the second fixing member 2. The slots 4 extend to the ends of the two fixing members 5 closest to the first fixing member 1 and the second fixing member 2, respectively. The fixing members 5 are designed to better secure the welding wire. When winding the welding wire, one end of the welding wire can be tightened onto the fixing member 5 connected to the first fixing member 1 first, and then the welding wire can be wound onto the winding member 3. Subsequently, the other end of the welding wire can be tightened onto the fixing member 5 on the other side. This prevents the end of the welding wire from loosening and falling off during subsequent processing, thus ensuring production quality.
[0028] As a preferred option, such as Figure 1 As shown, the axial length of the inner wall of the first irregular end 11 is greater than the axial length of the outer wall, and a first inclined surface 12 is formed between the inner and outer walls of the first irregular end 11. The shape of the first irregular end 11 and the degree of fit between it and the welding wire greatly affect the production quality of the irregular welded ring. The design of the first inclined surface 12 ensures that the welding wire fits the shape of the first irregular end 11 better when passing through the connection between the slot 4 and the first inclined surface 12. At the same time, the inclined surface design can increase the contact area, thereby providing greater friction and ensuring a more stable connection that is less prone to loosening.
[0029] As a preferred option, such as Figure 2 As shown, the axial length of the outer wall of the second irregular end 21 is greater than the axial length of the inner wall, and a second inclined surface 22 is formed between the inner and outer walls of the second irregular end 21. The inclination of the second inclined surface 22 forms a fixing groove at the edge of the second irregular end 21. This design allows the welding wire to fit tightly against the edge when wound to this location, and provides a certain degree of fixing, thereby achieving a better fit with the slot 4 on the second fixing member 2.
[0030] As a preferred option, such as Figure 3 As shown, it also includes a limiting part, which is fixedly connected to the fixing member 5. The radial dimension of the contact end between the limiting part and the fixing member 5 is larger than the diameter of the fixing member 5. The design of the limiting part can further fix the position of the welding wire and prevent the welding wire wrapped on the fixing member 5 from coming off. The two work together to achieve a better fixing effect.
[0031] In summary, this tooling for welding ring production solves the problem of insufficient precision in manual processing of irregularly shaped welding rings, improves processing efficiency, and meets the needs of mass production.
[0032] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
