[Prior Art] Disc 2: When the thread is used to turn the thread section, some of the burrs remain. However, "on the upper teeth peak, the hanging will affect the smoothness of the screw lock, and also: : The metal burrs are extremely sharp. 'The user has a slight accidental accident. The safety problem is caused by the accident. The b member will use the grinding stone to turn the screw into the screw, and the worker = to these burrs, * Influencing the overall efficiency and good, in other words, if it can be trimmed in turning, it can not only solve the problem that the teeth are not safely completed, but also the interference caused by the side. In view of this, the present invention is two + Productivity and yield. Product manufacturing and R&D experience. 1 Through the years of research on the problems faced by related products, we will continue to explore and test the embryos in the process of turning the screw teeth. Two sides: 1330227 Ϊ = method, in order to overcome the existing can not effectively solve the burrs [invention content] Therefore, the object of the present invention is to provide a tooth forming method, so that it can be completed at the same time as the teeth Remove 'no need After adding the whole secret I, to improve production efficiency ί yield. 〃

Through the realization of the foregoing technical means, the invention can complete the thread of the 6 1330227 without the edge of the thread, in order to effectively remove the thread segment from the self: the smoothness of the screw lock' while avoiding the use of economic efficiency and value, and enhance the competition Force and the second to cooperate with the circle and the figure, a preferred embodiment is made to familiarize the person skilled in the art with the understanding of the present invention. However, the following descriptions are only used to explain the hair of the hairpin, not (four) according to this The invention is in any form, and the invention is intended to be a modification or modification of the present invention. The invention is intended to be a method for forming a matte-free thread, such as: As shown in the second figure, the molding method utilizes one or more typical dental knives) Li one or most half knives (60) to selectively contact the embryo (10 „ inner diameter [the external thread of the invention is the main embodiment] step i thread (21) The thread segment (10) is formed (sH has a preparation step (S101), a tooth step, and the like, and in order to further increase the addition step (3) 04), a tool change step si05) and a Tool change to flash step S106). The material (3) 01) is to be turned into a blank (7), which is prepared in advance as a blank (10). As shown in the second figure, before the rii thread (21) is turned, the embryo can be 1〇) into the Ding, the desired treatment, such as grinding or forming a tapered surface, and this treatment 7 1330227 is usually completed in advance according to the requirements of the finished workpiece. The side teeth step (si02) is as shown in the third figure, Or the tooth blade (55) of most of the typical dental knives (50) continuously performs the turning of the plurality of passes of the rough and fine teeth on the outer diameter or the inner diameter of the blank (1〇). A threaded section (20) having a free end is formed on the preform (1〇) so that the threaded section (2〇) has a plurality of threaded teeth (21). The knife trimming step (S103) is the material The embryo (1〇^ thread segment (20) thread (21) has a slight repair of the tooth peak, which is replaced by a half-cutting knife (5〇) as shown in the fourth figure. 60), the blade (65) of the half knife (6 〇) has a horizontal flank (66) at an angle of 9 degrees to the vertical end surface of the blank (10) [as shown in the eighth figure], and Dental knife (6〇) The horizontal flank (66) is closed by the threaded section (20) for the movement of the shank (7)), since the horizontal flank (66) of the blade (65) of the half knives (65) only passes through the thread (21) , peak ', therefore, can remove the entire thread segment (2 ()) most of the thread (21) peaks of the burrs, and only the threaded section (2 〇) adjacent to the end of the first and second resistance teeth (21) There is a part of the burr remaining. The car half-step (S104) is as shown in the fifth figure, and the car is finished with the snail=(21) of the trimmed (1G) thread segment (2()). The movement of the half tooth uses the same half-knife?〇) 'and makes the half-knife (60) make a slight feed, and then the half-knife (6〇) is worm-infested, and °2讦讦The screw at the free end of the screw () is slightly advanced and then raised upward along the chamfer. In addition to the 8-1330227 of the non-formed peak of the 2nd screw (21) • Sharp burrs to completely remove the thread (20) The first],? The purpose of the bristles of the thread (21) is to complete the deburring of the threaded section (20). In the tool changing step (S1G5), the original half knife (60) is replaced with the original tooth (5〇) as shown in the sixth figure, and the plurality of passes are continuously fed. The fine tooth movement, for the threaded section (20) of the finished embryo (10), the thread (21) into the tooth, and further removes the fine burrs that may exist on the thread (21). • The tool change to the burr step (S106), and finally, as shown in the seventh figure, 'replace the tooth cutter (5G) with the above-mentioned half-knife (6G)' and make the half-knife (6 (6 ( )) The horizontal knives (66) are used to repair the teeth from the inner teeth of the snails (21) from the inside and the outside by the thread segments (20), due to the horizontal knives of the half knives (6j blades (65) The surface (66) only passes through the tooth peak of the thread, so that the burr of the tooth peak of the thread (21) can be effectively removed, and the quality of the entire finished product is improved. The above-mentioned method for forming the threadless thread of the present invention can effectively The burr on the tooth peak of the second thread (21) on the threaded section (2〇) of the embryo (1〇) is removed, so that the embryo (10) and the screw are not interfered with each other. The utility model can improve the smoothness of the screw lock, can prolong the service life of the component, and further, because it does not have a burr, the advancement can avoid the accident of the cut, and the safety of use is improved. Meanwhile, due to the safety of the invention The burrs are completed in the process of the car thread, and it is not necessary for the staff to use the grindstone or the wonderful cloth for secondary processing. The purpose of saving time and manpower is 9 1330227, which can improve product quality and production efficiency. As a whole, it can effectively save process time and cost, so it can achieve the purpose of the present invention. However, the above is only the comparison of the present invention. The present invention is not limited to the scope of the invention, and the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are still within the scope of the invention:
