New description: [New technical field] This creation is about a kind of screw, especially a kind of drilling and chip removal smooth, and can quickly improve the structure of the drill screw of the lock component. [Prior Art] A self-drilling screw is a relatively common locking component, especially an object widely used for locking metal materials; as shown in the first figure, it is a conventional self-drilling screw structure, the self-drilling screw ( 1) comprising a cap (H), a rod (10) extending from the bottom end of the cap (11), the rod body (10) is provided with an external thread (13) at its periphery, and a free end is provided with a drill tail (14) and a drill tail ( 14) A conical surface (141) is arranged at the end, and two symmetric flutes (142) are arranged on the circumference, and the two symmetric flutes (142) are respectively connected with the tapered surface (141) and the periphery of the drill tail (14). A drill cutting edge (143) and a cutting edge (144) are formed. When the locking action is performed, the drill cutting edge (143) and the cutting edge (144) are used to drill the object, and the external thread (13) of the self-drilling screw (1) is gradually locked while being drilled. The generated chips are lifted and discharged by the chip flutes (142) along the tail portion (14) to achieve stable locking and positioning. In the conventional drill-tail screw structure, the drill tail portion (14) is provided with two symmetric chip flutes (142), but the cutting edge (144) is disposed on the chip flute (1 42) and the drill tail portion. (14) The peripheral edge meets, so there is no chip removal space on the back side of the cutting edge (144). When the locking is drilled, it is easy to overcut and cause the chip to overheat, which causes the tail of the drill (1 2) to become blunt due to the tempering of the south temperature. In severe cases, there is even a smash that cannot be continued while drilling. [New content] 5 M329118 and the creator have the structure of the drill-tail screw, which is not smooth, and it is easy to have the blunt part of the drill to affect the drilling and riding degree. And the creation of the silk 'through multiple discussions and trials to reduce ^ multiple corrections and improvements, so launched this creation.

The main purpose of this creation is that the peripheral edge of the drill tail is convexly provided with the opposite blade lip, and the cutting edge is provided on the blade lip to increase the strength of the _edge and the appropriate chip removal on the rear side (4), which can prevent the lock from turning over and overcutting This causes the chip to overheat and achieves practical improvement. [Comprehensive application method] The following is a detailed description of the preferred embodiment of the present invention, as shown in the following figure, as shown in the second figure, the three-dimensional picture of the creation, and the third picture, the cross-section of the tail of the creation drill, the creation of the tail screw (2) comprising a cap (21), a rod body (22) extending from the bottom end of the cap head (21), the rod body (22) having two external threads (23) at the periphery thereof and a drill tail at the free end (24), a tapered surface (241) is arranged at the end of the drill tail (24), two symmetrical inclined flutes (24 M329118 2) are arranged on the circumference, and the two flutes (242) are adjacent to the circumference. Each of the convex portions is provided with a substantially square blade lip (10)), and the ends of the two chip flutes (242) and the conical surface (241) and the lip (243) are respectively formed with iron (four) (244) and Cutting edge (245). ~ #When the lock action is to be performed, as shown in the fourth figure, the lock action of the creation is shown as the intention, with the drill screw (2) drill tail (24) drill cutter (244) cutting-cutting knife (245) Drilling object (1), guiding the self-threading screw (2) (23) # Step into the object (4), while the chip generated during the drilling process, along the inclined flute (10)-) of the drill tail (10) The upper movement is discharged, and the opposite two lips (10) of the periphery of the drill tail (24) are designed to form an appropriate space (8) on the periphery of the drill tail (22) to prevent the locking drill-Shaw, and the overcut is The formation of the chip is overheated, and the effect of stable locking and positioning is achieved. For example, as shown in the perspective view of the fifth embodiment of the present invention, the trailing _(2) includes a stem (22) extending from the bottom end of the cap (2). The outer circumference of the body (10) is provided with two external threads (10), a free end M-view (24), the end of the drill (10) is provided with a conical surface (10), and the circumference is provided with two symmetrical spiral flutes (242,), and Adjacent to the two chip flutes (242 at the periphery, each side has a generally square-shaped blade lip (243,), and two chip flutes (10), and a conical surface (241) and a knife lip ( 243) The edge of the joint forms a cutting edge (2 slave) and a cutting edge (My), respectively. When the field wants to perform the locking action, as shown in the sixth figure, the locking action diagram of another embodiment of the present invention is shown by the drill cutting screw (244) and the cutting edge (245' of the drill tail screw (2). ) Drilling object (1), guiding the self-drilling screw (2) 7 M329118 The external thread (23) is gradually locked into the object (A). At the same time, the chip generated during the drilling process is spirally chipped along the tail (24). The groove (242') is moved upwardly and is designed by using the opposite two lips (243') of the periphery of the drill tail (24) to form a proper chip evacuation space (B) at the periphery of the drill tail (22) to prevent the locking drill When cutting, there is a situation in which the chip is overheated and the chip is overheated, thereby achieving the effect of stable locking and positioning.
由上述具體貫施例之結構’可得知本創作具有下述之 效益： 其鑽尾部（24)周緣凸設有相對之刀唇（243)、（243,） ，刀唇（243)、（243’）上設置切削刃（245)、（245,），使切 削刃（245)、（245’）強度增加及後側具有適當之排屑空間( B)，俾可防止鎮合鑽削時有過切造成卡屑過熱導致鑽尾部 (24)因高溫回火變鈍甚至斷裂之情形，進而實用性大幅提 升0 综上所述，本創作讀實已經達於突破性之結構，而具 有改良之創作内容，同時又能夠達到產紅_性與進; 性，且本創作未見之於任何刊物，亦具新穎性，當符合專 利法之規定，纽法提出細專_請，懇請韵局:查 委員授予合法專利權，至為感禱。 — 唯以上所述者，僅為本創作之較佳實施例而已，當不 能以之限定本_實施之範圍；即大凡依本創作中^It can be seen from the structure of the above specific embodiment that the creation has the following advantages: the periphery of the drill tail (24) is convexly provided with opposing lips (243), (243,), and the lips (243), ( 243') Set the cutting edges (245), (245,) to increase the strength of the cutting edges (245) and (245') and the appropriate chip evacuation space (B) on the rear side to prevent the splicing There has been a situation in which the chipping of the chip has caused the chip tail (24) to become dull or even broken due to high temperature tempering, and the utility is greatly improved. In summary, the creation of the book has reached a breakthrough structure and has been improved.
