Description

V. Description of the invention (1) [Technical field to which the invention belongs The invention belongs to a kind of effective solution which can solve the existing joining methods without destroying the butt ends of the rim and fully penetrate into the joint seam. The life of the hardening problem can also reduce the manufacturing of the rims [II. Prior Technology] According to the 'expressed aluminum bar of a common bicycle rim, it is rolled to 0 peripheral edges to form a series of perforations 1 wheel wire 1 2 ， And the rim; [〇 parallel insertion of the hole 16, the two insertion holes 7 ′ and the two mating ends 15 are engaged and the rim 10 is shown at the two mating ends 1 ”at both ends of the rim 10 suddenly and quickly Relatively striking, but because it was in a melted state, the two pairs of welds were then joined by the welding of the welded joints, so the heating and affecting the material structure was brittle, and if the welding was incomplete on the joint,) ' These pores will cause the joint to affect the rim joint technology field of the 10 butt end of the rim. Through crystallization, the special design of the brazing accelerant gap and the material pores is required, and the joint strength is insufficient and a secondary process is required. in this way Not only can the cost of rims be extended. ^ It is mainly a ring-shaped rim 10 as shown in FIG. 1, and the rim 1 ′ is provided with a locking member 13. The docking end 15 at both ends of the wheel is formed with 6 and an inner connector 1 can be inserted together. Form a complete rim 10; the traditional joining method is as shown in Figure 2, press the current, let the two ends butt joints 丄 5 creep, 15 general high-voltage current heating end 15 can be welded to each other (commonly known as ^ union method, which uses butt joint The integrity of the crystalline phase must be destroyed in the course of the end 15, and furthermore, the system is in collisional engagement, which generates a number of pores (commonly known as the pores ^, which is easy to break apart, " strength, shortening its service life 200413191 V. Description of the invention (2); Furthermore, after passing through a strong burr 18, this affects the degree of fit for the brakes, so it is smoothed. However, after grinding, the strength has not been asked. And the insufficient strength method, it is mainly used at the joint seam to weld by 2 5 to be used in the foot bulletin No. 376034 The content of the book, although the process produces burrs, the main welding area is welded, but those who want to order and the industry are not on both sides of the brake surface The absence of bumps is greatly improved because In order to deal with the stress, the two brakes clamped by a burr 18 of the wheel must first undergo a secondary grinding process, and then the knee joint of the joint should be solved, so additional manufacturing costs are required. For the wheel and secondary processing, as shown in Figure 3, a welding rod 25 is welded to the two butt ends 1 and the tread portion of the wheel rim is numbered "bike rim is clear. In order to avoid the rim from secondary grinding, you can Improving the ratio is better than using local welding to obtain such a dare. Its burr (because there is no welding) solder, and its desire can only be said in practical use. In theory, the joint of the article 10 will be the entire rim of the wheel. And tires and processing and grinding, this combined processing surface is hardened after being removed from the hardened layer, and the ring joint problem is heated by the rim 1 and also 5 (also known as the two joints with the joint structure 10). The problem, welding south about 4 full joint patent solves the problem, but in local welding, once the force is formed to form a protruding joint, the rim 1 of the rim 1 0 will be welded and researched, resulting in invisible improvement. Made by law Two pairs of currents are used for Ya Welding patent application ": the side brake only requires 0% welding strength, and its welding will have a considerable impact. The resulting joint is brittle and the new joint end is 15 Melting electrode); the welding request information such as the patent application said that the strength of the rim inside the joint before joining. The use of only to avoid the surface of the rim area is still a strong risk of rim joint strength, its external

Fenyi concentrated on the head and tail ends of the welding place and quickly destroyed, and the concept of the "international patent" has not seen the local welding of the rims as in its patent specification II, but a comprehensive welding method. Create side items. Moreover, it still has the same problem, and the welding bead cannot be completed. As it can be used, it is obvious that the broken crystals are not completely welded and the solution is completely resolved. The rim description can reduce the derivation of the complete fusion of the wool phase, and it is not allowed to join the strength and the height of the edges and the solution to the air holes (4 The hole is easy to be polished for secondary processing and joint strength, so it) and embrittlement are processed. The apparent hardening process can be seen through the above description. In practice, there are some problems of lack of joint strength and embrittlement. The main purpose of the present invention is to affect the joint strength of the service life of the rim and avoid secondary. For this reason, the inventor's experience in R & D and manufacturing, in-depth discussion of the problems and needs, and hard research and trial work, finally the strength of the bicycle rim joining method while reducing its manufacturing costs. Due to the problems solved by the existing method of joining the self-rims, they generally require the phenomenon of secondary processing and manufacturing costs at the same time. Therefore, how to improve the wheel processing to improve its economic benefits. Faced with and actively seeking solutions during the manufacture of bicycle rims, a long-successful development has developed a method that can improve the engagement and extend the life of the rims. Therefore, the main claim of the present invention is a method for joining bicycle rims. To extend its use; &
