Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vibration welding, and in particular to a vibration welding structure having both planar and curved surface parts. Background Art
[0002] Traditional vibration welding relies on the principle of micro-vibration. Through the high-speed up, down, left and right movement of two objects at a micro-distance relative to each other, a large amount of heat is generated through friction movement to achieve the melting of the friction surfaces of the two welded parts and reach a fully molten state, so that the weld reaches the material's own strength. The welding surface structure of traditional vibration welding is a "one" type plane. In the friction direction, there are certain angle requirements, which limit the shape of the product. It is basically used for parts with relatively flat and straight welds, and is rarely used in complex parts such as air filters, expansion tanks, and torque tubes that have both flat welding areas and curved welding areas. Therefore, for the above-mentioned parts with both flat and curved surfaces, hot plate welding is usually used or the parts are directly modified. However, thermal deformation will occur during the heating process of the product. Modifying the parts may not meet the standards and make the parts unusable.
[0003] In the process of implementing this application, it is found that the above technology has at least the following problems:
[0004] 1. After traditional vibration welding, there is overflow around the weld of the parts.
[0005] 2. When using traditional vibration welding for parts with both flat and curved surfaces, the vibration of the upper and lower welded parts in the curved welding area affects the welding effect of the flat welding area because there is no relative movement space. Utility Model Content
[0006] In view of the above-mentioned problems of the prior art, in order to solve the problem that traditional vibration welding cannot weld complex parts, the present application provides a vibration welding structure having both flat and curved parts.
[0007] To achieve the above objectives and other related objectives, this application adopts the following technical solutions:
[0008] A vibration welding structure having both flat and curved parts comprises an upper welding part and a lower welding part, wherein the upper welding part is provided with a first plane, on which vibration welding ribs and glue-coated welding ribs are provided, and the lower welding part is provided with a second plane, on which first grooves and second grooves corresponding to the vibration welding ribs and the glue-coated welding ribs are provided, wherein when the upper welding part and the lower welding part are welded and buckled, the vibration welding ribs extend into the first grooves, and the glue-coated welding ribs extend into the second grooves.
[0009] As a specific solution of the utility model, it can be preferred that: a gap is left between the vibration welding rib and the side wall of the first groove, and a gap is left between the glue-coated welding rib and the side wall of the second groove.
[0010] As a specific scheme of the utility model, it can be preferably: before welding, a gap is left between the first plane and the second plane, the vibration welding rib is fitted with the bottom of the first groove, and a gap is left between the glue-coated welding rib and the bottom of the second groove; after welding, the first plane and the second plane are fitted, the vibration welding rib is fitted with the bottom of the first groove, and the glue-coated welding rib is fitted with the bottom of the second groove.
[0011] As a specific solution of the utility model, it can be preferred that: the glue-coated welding rib or the bottom of the second groove is coated with adhesive.
[0012] As a specific solution of the utility model, it can be preferably that: the distance between the gap between the first plane and the second plane is the same as the distance between the gap between the glue-coated welding rib and the bottom of the second groove.
[0013] In summary, the present application includes at least one of the following beneficial technical effects:
[0014] 1. Before welding, the vibration welding rib extends into the first groove and fits with the bottom of the first groove to form a friction surface. After welding, the overflow caused by the friction of the vibration welding rib will be collected in the first groove, so that the overflow will not overflow; in addition, the gap between the first plane and the second plane is the same as the gap between the glue-coated welding rib and the bottom of the second groove. When welding, when the glue-coated welding rib fits with the bottom of the second groove, the first plane and the second plane also fit together, which will make the outer surface of the part more beautiful. 2. The vibration welding rib and the bottom of the first groove are welded by vibration friction, and the glue-coated welding rib and the second groove are coated with adhesive to make the part more firm; at the same time, the first plane and the second plane fit together to form a sealed space in the second groove to prevent the entry of air and water vapor, thereby ensuring the coating effect. 3. A gap is left between the vibration welding rib and the side wall of the first groove, and a gap is left between the glue-coated welding rib and the side wall of the second groove. When welding parts with both flat and curved surfaces, the vibration welding rib and the side wall of the first groove, and the glue-coated welding rib and the side wall of the second groove will not collide with each other, will not affect the welding effect of the vibration welding rib and the first groove, and will not cause cold welding or leaking welding.

The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.
[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0028] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings.
[0029] The embodiment of the present application discloses a vibration welding structure having both planar and curved surface parts.
[0030] like Figures 1 to 6 and Figure 8 As shown, a vibration welding structure having both flat and curved parts comprises an upper welding part 1 and a lower welding part 2, wherein the upper welding part 1 is provided with a first plane 3, the first plane 3 is provided with a vibration welding rib 31 and a glue-coated welding rib 32, the lower welding part 2 is provided with a second plane 4, the second plane 4 is provided with a first groove 41 and a second groove 42 corresponding to the vibration welding rib 31 and the glue-coated welding rib 32, when the upper welding part 1 and the lower welding part 2 are welded and fastened, the vibration welding rib 31 extends into the first groove 41, and the glue-coated welding rib 32 extends into the second groove 42, before welding, the vibration welding rib 31 extends into the first groove 41 and fits with the bottom of the first groove 41 to form a friction surface, and the overflow generated by the friction of the vibration welding rib 31 during welding will be collected in the first groove 41, so that the overflow will not overflow, and the outer surface of the part will be more beautiful. Figures 1 to 3 For air filters, of course, expansion tanks, torque tubes, etc. are all vibration welded structures with flat and curved parts.
[0031] A gap is left between the vibration welding rib 31 and the side wall of the first groove 41, and a gap is left between the glue-coated welding rib 32 and the side wall of the second groove 42. When welding parts with both flat surfaces and curved surfaces, the vibration welding rib 31 and the side wall of the first groove 41, and the glue-coated welding rib 32 and the side wall of the second groove 42 will not collide with each other, thereby not affecting the welding effect after welding, and not causing cold welding or leaking welding. Due to the gap design, the vibration welding rib 31 will rub and produce overflow, and the overflow will overflow into the gap, making the outer surface of the part more beautiful.
[0032] Before welding, there is a gap between the first plane 3 and the second plane 4, and the vibration welding rib 31 fits with the bottom of the first groove 41, ensuring that only the vibration welding rib 31 rubs against the bottom of the first groove 41 during the welding process, and no friction is generated between the first plane 3 and the second plane 4, and no additional overflow is generated, which does not affect the aesthetics of the parts with both planes and curved surfaces. There is a gap between the glue-coated welding rib 32 and the bottom of the second groove 42, and no friction is generated between the glue-coated welding rib 32 and the second groove 42 during the welding process, and they are only bonded by the adhesive 5. If the glue-coated welding rib 32 is brought into contact with the bottom of the second groove 42, the friction effect between the vibration welding rib 31 and the bottom of the first groove 41 will be affected, resulting in the friction surface temperature being too low to reach the melting level, and only reaching a plastic state, and barely combined together, resulting in a cold weld. Figure 7 and Fig. 9As shown, after welding, the first plane 3 and the second plane 4 are fitted together, the vibration welding rib 31 is fitted together with the bottom of the first groove 41, and the glue-coated welding rib 32 is fitted together with the bottom of the second groove 42. During the welding process, the vibration welding rib 31 and the bottom of the first groove 41 are rubbed together to generate heat and melt together, and the generated overflow is collected in the first groove 41. In addition, due to the melting effect, the height of the vibration welding rib 31 is reduced, so that the first plane 3 and the second plane 4 are fitted together, and the glue-coated welding rib 32 is fitted together with the bottom of the second groove 42, forming a sealed space in the first groove 41 and the second groove 42 to prevent air and water vapor from entering, thereby not affecting the welding effect.
[0033] The adhesive-coated welding rib 32 or the bottom of the second groove 42 is coated with adhesive 5 , so that the curved surface welding section after welding can be bonded by the adhesive 5 to make it more firm.
[0034] The gap H2 between the first plane 3 and the second plane 4 is the same as the gap H1 between the glue-coated welding rib 32 and the bottom of the second groove 42; when H1 is smaller than H2, the glue-coated welding rib 32 will not contact the bottom of the second groove 42 when welding is completed. If the glue-coated welding rib 32 is coated with adhesive 5, the glue-coated welding rib 32 cannot be bonded to the bottom of the second groove 42. If the bottom of the second groove 42 is coated with adhesive 5, the bottom of the second groove 42 cannot be bonded to the glue-coated welding rib 32, and the coating effect cannot be achieved. When H1 is larger than H2, the glue-coated welding rib 32 will not be in contact with the bottom of the second groove 42 when welding is completed. When the glue-coated welding rib 32 contacts the bottom of the second groove 42, the first plane 3 and the second plane 4 are not fitted together, which will cause air and water vapor to enter the second groove 42, that is, the coating area, and will affect the glue, thereby causing the self-adhesive 5 to harden and solidify and fail, affecting the final welding effect; when H1 is equal to H2, when the glue-coated welding rib 32 fits with the bottom of the second groove 42, the first plane 3 and the second plane 4 also fit together, so that a sealed space is formed in the second groove 42 to block the entry of air and water vapor, thereby ensuring the coating effect and making the parts with both flat and curved surfaces more durable.
[0035] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
