Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a anti-loose structure of a high-strength washer-free countersunk head screw and a processing method thereof, and particularly to a anti-loose tooth of a high-strength screw head Structural design, and the new designer of the new processing methods for making this structure. [0002] [Prior Art] Please refer to Fig. 1 to Fig. 3, in the conventional art, the anti-loose measures for the high-strength screws (that is, the hexagonal head screws) are as shown in Fig. 1, The anti-loose pad 圏10 is used to provide the elastic positive force pressing after the screw 1 1 is locked, and the friction force between the screw 1 1 and the thread of the locked compound can be maintained normally, thereby achieving the screw. After the 1 1 lock compound, it is not easy to retreat by itself. [0003] Over the years, it has further facilitated the commercialization of the application components and facilitated the group 1, and thus avoids the loss of the loosening washers: easy to miss (missing), etc., especially developed as shown in Fig. 2 The anti-loose screw structure is attached to the bottom surface 1 1B of the screw head 1 1A of the screw 1 1 , and deliberately forms an anti-slung bottom flange 1 3 '. The anti-slung bottom flange 13 usually has a specific screw head 11A The bottom surface 11B has a wider area, and the bottom surface 11 B is formed with a plurality of radial anti-loosening teeth 131 to achieve a self-locking structural design; however, the bottom end of the screw head 1 1A is self-contained. The type of screw forming the anti-slung flange 13 which is expanded outward is naturally required to allow the anti-slung flange 13 to pass through the object to be locked on the object to be locked. The larger fisheye pit 1 4 1, and so designed, seems to lose the use of the built-in slot with 090131917 form number A0101 3 / total 24 page 0992055899-0 201213675 1 lc, can reduce the lock hole ( The main consideration of the size of the above-mentioned fisheye pit; therefore, often In the industry of using such screws, it has been considered whether the above-mentioned anti-feb teeth can be directly disposed on the bottom surface 15 of the screw head of the two-strength screw 1 1 without providing the outer-expanding bottom flange; however, the above The concept is still not possible due to the following reasons: [0004] First, please refer to the first to fifth figures, because of the high-strength screw 1 1 screw head 1 1 A, in order to meet the needs of the use of strength, The axial height of the screw head 1 1A is higher than the screw head of the general-purpose screw, that is, the thickness is thicker, and the above-mentioned: the formation of the anti-loose 3113 1 is the die 2 punched by the screw head, in the punching At the same time as the lock groove 1 1 c is formed by the predetermined molding groove 2 〇 2 on the bottom surface of the cavity of the bottom mold 20; however, it has been used for punching the inner lock groove 1 C for a long time. Punch die 2 1, when the impact is applied to the screw head 1 1A to be machined in the bottom mold 2, the impulse is mainly consumed in the stroke of the forming inner lock groove c -, and can be directly from the screw _ i 1 瑞, the impact energy is transmitted to the bottom surface of the screw head 1 1 A 1 1 B and the bottom mold 20 (please refer to paragraphs 4 and 4) 5A)) between the bottom surfaces, therefore, in actual operation, the inner lock groove 1 1 C can be punched first by the first punch die 2 1 in a plurality of processes, and then another segment The outer pressure portion 2 2 of the mold is intended to produce an expanded anti-slung flange 13 as shown in the second and fifth figures, and it can be seen that the processing of the conventional high-strength screw head 1 1 A is known. It is apparent that it is difficult to form the anti-loose teeth 1 3 on the bottom surface of the high-strength screw head 1 1A which does not have the expansion-type anti-slung flange 13 , and therefore, it is greatly affected in the structural design of the still-strength screw. limits. 099131917 Form No. A0101 Page 4 / Total 24 Page 0992055899-0 201213675 [0005] Further, as shown in Figures 4 to 5, when the anti-loosening teeth 1 3 1 are manufactured by the above-described processing technique, In the molding groove 2 0 2 on the bottom surface of the original bottom mold 20, air which is not discharged smoothly is accumulated, and therefore, although the high pressure from the mold 2 is received during the punching process, the air will be It is compressed into a very small volume, but because the internal pressure generated by the compression is extremely large, it is enough to hinder the material forming the screw head 11A from smoothly and completely entering the space filled with the air, so if the anti-loosening tooth is to be 1 3 1 is designed too close to the screw 1 2, it will be due to the unreachable energy transmission and the obstruction of the residual air, so that usually during the finishing process, it will form on the anti-loose teeth 1 31. The light and heavy missing material is not fully toothed. 1 3 2 Therefore, the same industry uses the expansion of the anti-slung flange 13 and the boundary between the bottom surface 1 1 B and the screw 12 to form a concave ring groove. 1 3 3 way to avoid the phenomenon of the missing tooth 1 3 2; however In this way, not only the residual air can not be effectively eliminated, but the flaws and unsightly phenomena of the tooth type still exist, and the concave state of the intersection portion of the concave ring groove 13 3 and the screw 12 will be more easily formed. The intensity defect points of stress concentration have a great impact on the safety of use, and there is a need to improve it. [0006] In addition, as shown in FIG. 3, the tooth peaks 1 3 1 0 of the conventional anti-loose teeth 1 3 1 are all set to a sharper cross-sectional shape, so that not only the molding is difficult, but also the application is high. When the lock force is locked, the peaks 13 10 usually cause the scraping of the inner surface of the fisheye pit 141 of the locked body 14 to cause the damage of the scraping material, which will affect the stability of the re-locking. The lack of improvement is necessary. SUMMARY OF THE INVENTION 099131917 Form No. A0101 Page 5 / Total 24 Page 0992055899-0 201213675 [0007] The present invention is directed to the above needs, and in particular, to provide a novel high strength non-washing countersunk head screw anti-loose structure processing method, which is In a bottom mold for punching the screw head, a joint air passage is respectively formed at a boundary between a predetermined anti-loosening tooth forming groove and a screw through hole in a bottom surface of the bottom mold. Therefore, in the process of punching the screw head, each anti-loosening tooth can be formed smoothly on the bottom surface of the screw head; and the air passage in the punching process can effectively eliminate the air remaining in the forming groove in the punching process, thereby effectively improving the conventional tradition.

The inner space of the groove 6 and the air passage 6 1 3 is such that a convex structure 4 5 1 is formed between the respective anti-loose teeth 5 〇 and the screw 40 and protrudes from the bottom surface 34 of the screw head (for example, the first 3 The figure shows that the direct full-tooth shape of the joint is able to effectively remove the air remaining in the mold, thereby improving the incompleteness of the tooth formation caused by the conventional processing method and the ability to appropriately supplement the strength of the part; In addition, if the above-mentioned punched bottom mold 6 〇 inside the bottom surface 6 i 丄 and 099131917 form number A0101 0992055899-0 8th Page / A total of 24 pages 201213675 The intersection of the screw through hole 6 2, especially the formation of a large arc of the extended ring curved surface 6 1 4, in the stamping molding, the formation of the screw head bottom surface 34 and the screw 40 is obvious The large arc-forming face 3 5 (as shown in Fig. 9) makes a reinforcing structure formed at the junction, which further enhances the resistance to stress concentration of the part, and the safety is better. Please refer to FIGS. 10 and 10A again. When the high-strength washer-free countersunk head screw 30 formed by the present invention is used to lock a locked body 1 4 A, it is not only stable but also exhibits high strength. Locking the locked bodies 1 4 A, and when the high pressure locking is applied, since the tooth peaks of the respective anti-loosening gingivals 50 are formed as the micro-arc surfaces 501, except when processed and formed as described above, When the anti-loose teeth 50 are more easily fully enriched, when the high-locking force is applied, only the bottom surface 142 A of the lock fish hole 141A of the lock body 1 4A is pushed and squeezed, It will be like the sharp tooth peak of the traditional anti-loosening tooth 1 3 1 , when the gravity is locked, the damage caused by the scraping material generated directly on the inner bottom surface of the fish eye pit 1 4 1 , the screw of the invention is applied More ideal and perfect, please refer to Figure 14 again, which is the screw 30 made by the invention. If the screw 40 is close to the bottom surface 34 of the screw head, it is larger than the diameter of the threaded portion 4 1 . Forming the joint base portion 4 2 further has the effect of further strengthening the portion to reduce stress concentration, which may be another possible embodiment of the present invention. . In summary, the present invention does provide a structure and a manufacturing method thereof which can effectively improve the anti-loose effect of the conventional high-strength washer-free countersunk head screw, and not only construct a perfect anti-loose structure, but also use a special mold structure to achieve The quality of anti-loosening teeth that can not be achieved by traditional technology is indeed a breakthrough in the design of high-strength countersunk screws. 专利Proposed patent application according to law, I am 099131917 Form No. A0101 Page 9/24 pages 0992055899-0 201213675 Please give us an early date It is what I hope.
