Description of the invention (1) Cross-reference of related applications (please read the notes on the back before filling this page) The application for this invention claims to be in 2001 The name of the application filed on June 7 is "Threaded Rolling Die, Low Deformation Rate," the priority of US Provisional Application No. 60 / 296,626, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION The present invention is roughly The improvement of the thread rolling die and more particularly relates to an improvement in the design of the rolling die which reduces waste and produces better fixings. The function of using a thread rolling die to generate threads on a bolt is conventional, but, Over the years, there have been many important improvements in methods and processes, especially in the area of the thread transition. The thread transition, also known as the tail region of the thread, is from the last complete thread to the shank of the screw inspection or The area defined by the distance of the grip part. In the practice of rolling bolt threads, the length of the thread disappearing is about 2 pitches. However, in aviation applications, reducing the transition section has been proven to be Very useful. A smaller ^: segment is necessary because it reduces weight by reducing the length of the entire thread 'to shorten the thread transition segment without compromising its effectiveness. The structure of the U.S. patent has successfully reduced this The thread transition or the tail region of the thread is far less than 1 pitch length. However, the sudden change in the cross section to improve the thread transition section has caused great difficulties in the thread rolling process, which is in the use of high strength and = Display materials such as Chin and other high-strength resistances will become particularly apparent when attacking. These problems are manifested in the grinding, joining and multi-paper rule (⑽) A grid (2 songs 297) added to the bottom of the thread. Gong ^ ----- -4- Wujian the 30 561078, the description of the invention (the frequency and discontinuity of a man's cut. So 'make the snails with the characteristics of the length of the transition zone of the shrinking pattern! Do not occur any unacceptable The thread deviation is necessary. In addition, "傕" = small stress and deformation rate are generated in the thread transition area of the screw inspection. Summary of the invention The present invention relates to an improved thread rolling die, which includes == and the bottom edge, Flat cone The die end and one are used to create-the fixed two faces. Formed on this face is-a series of ridges including most of the -pre-sides, these ridges are complementary to the thread to be formed and Relative to the top and bottom edges, there is an acute angle. When a blank is rolled in the set of molds, the convex ridges can be used to create a thread. The β mold contains -forms-located at the top edge of the mold. A stepped bevel of a part of the top edge between the surface and the vertical plane; the bevel is at a predetermined angle with respect to the top edge surface, and the ridge crossing the stepped bevel has a top edge with the mold The predetermined angle extends to the ends of the stepped bevel, and the ends ^ smoothly merge into a generally flat surface extending to the top edge surface of the mold, so that the substantially flat surface such as 虡 is less than ⑹ degrees relative to the surface of the mold The end of the angle-improving die is extended away from the top edge of the die at an angle of 60 ° and away from the top edge of the die at an angle of about a degree. The implementation of the new structure of the present invention minimizes negative effects and continues to reduce the acceptable distance of the full thread in close proximity to the gripping portion. This feature is achieved by changing the manufacturing of the screw and pattern rolls The change is to make the flat narrow surface and the vertical surface of the mold at an angle of less than 60 degrees instead of the paper size (standard) A4 specification (21 () χ297)

The improvement in the structure further includes that the top edge of the mold extends to the end of the vertical plane of the mold and extends away from the top surface of the mold at an angle of 60 degrees. In addition, the modification changes the ends and makes its angle approximately 30 degrees from the vertical position to produce a smoother thread. In an exemplary embodiment, the fixed mold and the movable mold can produce less stress and deformation in a thread transition area of a fixed part when manufacturing a fixed part with a specific size, and the structure not only reduces the thread in the thread. The stress and deformation rate in the transition region can be smoothly combined with a blank of a fixed piece between the fixed mold and the moving mold.

Description of the invention (5) A stepped inclined surface 59 at a part of the edge. This surface is at an angle with respect to the top edge surface 53 I. Therefore, the stepped inclined surface 59 There is only a gap of 5 degrees from the upward side π of the ridges 56 that terminate at these ridges 56. In practice, the bevel 59 is made to merge with the side 57 that intersects it. The "slope" should have a vertical dimension equal to at least twice the pitch of the thread to be formed to ensure proper clearance when the thread is formed. The ridge 56 that intersects the stepped slope 59 has a fairly steep end, Therefore, the entire cross-sectional dimensions of the ridges 56 near the location where they terminate are symmetrical on both sides of their longitudinal axis. The tails of the ridges 56 have a transverse circle approximately symmetrical to the ridge axis The edge end 60, preferably, the tail portion at its pitch diameter does not exceed a quarter of the peripheral edge of the thread to be formed to the surface 59 and the round edge end 60 of the ridge 56 smoothly merges into the extension To the flat narrow plane 61 of the top edge surface 53 of the mold, the result is that the stepped structure of the bevel 59 divides it into multiple segments, and each segment connects the side 57 of one of the ridges 56. The narrow surfaces 61 are connected to The raised ridges are transverse, and are perpendicular to the longitudinal axis of the raised ridges. "The distance between the raised ridge ends 60 is set to the die end 62 at the beginning of the thread rolling, and the height is from one to the bottom. Increase one by one to the opposite end a. * As shown in Figure 1 above, the thread tail is very steep when it leaves the top of the die and the termination of the thread in the region of the tail (thread transition) is short and rapid. Although this feature is necessary to reach the minimum distance of a full thread in a dimension as close as possible to the grip or handle, it often produces unnecessary multiple cuts, grinds, joints, and other discontinuities.

Description of the invention (10) Ends 160. These ends 160 preferably form a convex edge with a compound curve. Therefore, the ridges 120 are close to where they terminate so that their full cross-sectional dimensions are symmetrical on both sides of their longitudinal axis. The sole tails of the raised ridges are formed by the transverse rounded end 160 'which is approximately symmetrical to the raised ridge axis, as shown in Figure 12, and an angle of 15 degrees extends from the beginning of the notch and the radius along the root radius until it It ends at the edge of the die. The implementation of the present invention and the new structure shown in Figures 2 to 13 minimize the negative effects and still continue to reduce the distance of a full thread in an acceptably close to the size of the grip, this feature is changed by This is achieved by making the thread rolling dies 4, which changes the surfaces 162 and the vertical surface j 18 of the dies at an angle of less than 60 degrees, rather than perpendicular to the longitudinal axis of the ridges as is known in the art. (As shown in Figure 1). In addition, the conventional technique shows that a radius of 60 (as shown in Fig. 1), which is a transition portion of the thread from an angle of 118 to 90 degrees from the vertical surface of the mold, extends to a radius of 60 and leaves the top of the mold. The top thread has sharp corners. The improvement in this structure not only forms a round edge at this point (indicated by reference numeral 160 in Figures 2a, 2b, and 2c), but also the top edge 102 extends to the end 16 of the face 118 of the mold, and Extending away from the top surface 102 of the mold at an angle of 60 degrees. The conventional technique further reveals that the surface 60 (shown in FIG. 1) is a surface 55 (shown in FIG. 1) extending away from the mold and is a flat surface 53 (shown in FIG. I) on the top of the mold. (Shown) vertical. On the other hand, the modification changes the surface 160 and makes it an angle of about 30 degrees with respect to the vertical position. This structure is shown in the above figures 2, 2a, 2b, and 2c.
