The nearly round shape belt with the tooth and the hem is designed to simplify the number of machine equipment and mold sets required, and greatly improve the productivity and yield quality, and reduce its cost and increase its Competitive toothed belt manufacturing method (2). • [Prior Art] According to the 'Practical Method of Manufacturing the Toothed Belts', please refer to the “Method of Manufacturing the Toothed Belts” that the applicant has previously obtained the approval of the fishing bureau for the 122nd Song No.8. The forming steps are as follows: A: A thin plate body is placed in the mold set as a punching hole for the guide hole; B: the thin plate is moved before the same time as the same wire, and the upper set is simultaneously punched to form another row of guide holes, boundary grooves and joint portions. C. Then move the thin plate body forward __ more than the same stroke, and then make the above-mentioned mold set Lu (5) step again to punch another row of guide holes, another row of boundary grooves, another row of joints and teeth D; then move the Lai board age forward - cut the same stroke, and then make the above mold group synchronously punch the other row of guide holes, another row of boundary grooves, another row of joints, another row of teeth and Folding; E. Then move the board to the front axis—the phase on the button is pure, and the upper group is synchronously punched again to make another row of guide holes, another row of boundary grooves, another row of joints, and another - the toothing portion, the other folding edge and the cutting separation; by the above processing (four) 'as long as the thin plate body is placed in the same-group machine and die Within the group and 3 1362974 * » If the progressive machining stroke exceeds n times, a bundle can be directly manufactured, and each additional punching and punching process can be used to make another one. The other strip has been cut apart and has a hem. The remaining belt. Although the above-mentioned creations can achieve the original purpose of creation, they are highly praised by the industry and the general operators. However, in view of the rapid development of technology in the industry and the creators are not spared, they are working hard to improve. It makes the perfect imperial m ship countless times of the Jing experimental test and the inductive manufacturer in the actual production _ should be opinioned, found that #下_题麟进-step improvement: 1. Because the above processing steps can produce independent straight strip folding The edge and the toothed belt are used as a combination with the outer gambling. However, after the straight bundle is combined with the core, it must be moved to another machine to be used for the belt _ processing ( That is, from a straight strip to a circle shape) 'so' will make the finish - the finished product must be a segmented way of adding and its completion - the finished face X can not be minimized, _, miscellaneous manpower for handling movement After the second processing, he made the manpower county surplus cake lack of money and unreasonable effective South is a major problem. • 2 • As stated in point 1 'Because of the segmentation process, a band-shaped band can be produced, so that the number of required sets can no longer be reduced to a minimum, and thus it is impossible to reduce the overall Cost is another big problem. In view of the above, the invention has been proposed in view of the above-mentioned conventional techniques, and a toothed beam manufacturing method (2) has been proposed to effectively overcome the above problems. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for manufacturing a toothed belt (2), which is characterized in that after the same stroke of the upper and lower parts of the mold set (4), Forcing the above-mentioned mold set to be synchronously divided and formed into another row of holes, another - boundary groove, another 4 rows of joints, another peach funp p, another fold edge to form a more mature body shape; After the stroke on the sheet LW, the mold step is again punched to form another row of guide holes, another & row boundary groove, another row of joints, another row of teeth, another row of flanges, ^cutting the "connected portion" and the synchronization so that at least the front part of the strip has been removed from the front direction and the bottom is turned into a nearly round shape in the asymptotic direction; finally, the thin plate body is also moved to the second After the same stroke, the mold group is synchronously punched again to form another row of guide holes, another row of boundary grooves, another row of joints, another row of teeth, another row of folds, synchronous cut, < The junction of the t-synchronization causes the at least one end of the strip to be separated from the beginning and the asymptotic The direction is bent into a nearly round shape and the cutting is separated; so that the thin plate body can be moved by the fixed stroke in the mold group and the progressive processing is more than n times, and the independent circle shape of each of the parts and the hem can be directly produced. The belt is used to achieve a complete set of modular processing, and the number of processing machine equipment and mold sets required by the belt can be minimized, so as to simplify the "outside of the operation of the X", and also __The processing stroke of the mold group can greatly ask the yield. The quality can keep the production process continuous and consistent without interruption, and can surely avoid the migration of mature ages. The step of adding steps to greatly increase its production capacity, thereby reducing its cost and improving its competitiveness is its progressive effect. [Embodiment] This creation is about a method of manufacturing a toothed belt (2), see In the first to eleventh drawings, the forming steps are as follows: <A> A thin plate body 2 is placed in a mold set (not shown) for punching of the guide holes 2 (as shown in the first figure); < B > moving the thin plate 2 forward After the same stroke of more than one time, the above mold group is made 1362974
