Description of the invention: [Technical field to which the invention pertains] In particular, it is a manufacturing method for a manufacturing method that is related to a manufacturing method. [Prior Art] Referring to Fig. 1, a conventional Huashi, soil θ teaching is to use a punch (not shown) to punch out a plurality of Huasi finished products U on a metal plate 1, and the manufacturing steps are prepared first - The metal plate i of a predetermined thickness is placed in the punching machine to directly cut out the hollow ring-shaped finished product 11 in the metal. However, since the metal sheet 1 is subjected to the processing of the flushing material, the residual material 12 located around the finished product 11 of the Huashi will be left, forming a large amount of waste: the mechanical strength of the waste product which is produced and produced by the company. Poor, the peripheral cut section is sharper and the handle is 'lower product quality, so its method still needs to be improved. Referring to FIG. 2, a conventional manufacturing method of the present invention is to cold forge a wire 22 into a finished product 23 by using a forging device 21, the forging device 21 having a hollow feeding seat 211 and a jig 212. A hollow female mold 213, and a male mold 215 having a punching rod 214, in the following description, the upper side of the drawing is the front side and the lower side of the drawing surface is the rear side. The Was manufacturing method comprises the following steps: (a) Clip feed: the wire 22 is fed into the feed holder 211, and then the wire 22 passing through the feed holder 211 is clamped into the master mold 213 by the clamp 212, and is advanced. The length of the extended female mold 211 is given to divide the wire 22 into a pinch section 221 located in the female mold 211, and a working section 222 protruding outside the female mold 211. 3 201036731 (b) Initial forging type: The driving male mold 215 is moved backward to the female mold 2i3, and the working portion 222 protruding from the female mold 213 is stamped, and the working portion 222 is initially forged into a flat shape and has a desired thickness. Released from the exterior 223. (c) Re-forming: then driving the punching rod 214 located in the center of the male mold 215 to punch the central portion of the release 223, and pushing the clamping section 221 back a distance to the opposite side. At the center of 223, a perforation is punched out to form the finished product 23, and at the same time it is separated from the pinch section 221. (d) Finally, the driving male mold 215 is moved away from the female mold 213 and moved back to the original position, and the finished product 23 is separated from the forging apparatus 21 for output. Repeat the above steps to repeat the forging process. Although the above-mentioned manufacturing method can be cold forged, the wire 22 is forged into a finished product 23, but by the above steps (4) to (8), the working portion 222 in the shape of a round rod is forged into a flat only by one swaging. The circular release 223 has a large amount of deformation of the material, which will result in poor mechanical properties of the finished 232 finished product. Moreover, since it is directly cold stamped on the wire, the working section 222 is connected to the rear clamping section 221, and the clamp 212 and the feeding base 211 are clamped to the clamping section 221, so in the punching and forging process, the clamp 212 and The feed base 2U will withstand the impact force of the punch rod 214 and the relative friction from the pinch section 221, causing the clamp 212 and the feed base 211 to be worn and damaged. In the re-forging step, the punch 2 μ is punched and punched, and the pinch section 221 connected to the rear is pushed up to separate the Huashicheng σα 23 from the pinch section 221, and the punching force required for this step is required. Larger, it will shorten the service life of the mold and fixture, not only affect the accuracy of the clamping feed, increase the non-performing rate, resulting in cost loss that is difficult to ignore, 201036731, and when the forging design is shut down, It will also cause high-speed mass production work to stop, resulting in reduced production and poor production efficiency. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a method for manufacturing a finished product which can produce a mechanically good finished product. Another object of the invention is to provide a method of manufacturing a Watts that extends the service life of the forging equipment.

Intercepting field: straighten the wire 4 into the forging equipment 3, and = use-cut device (not shown) will gradually The feeding wire 4 is cut to intercept a slave length, and the wire 4 is a cylindrical blank 4, as shown in Fig. 4, and the length of the 41 is calculated according to the volume size required for the finished product. Blank: Referring to Fig. 4 and Fig. 5, the brake field + m is 0 〃圃 5 using - pinch device (not shown) = _ material 41 is sent to the first punching device 31, and placed in the first master die 312 3U inside and drive the first - male mold 314 to the first female mold 312 to move 201036731 "to drive the first punch 313 into the first cavity 311, while the material 41 is initially punched" to form a thick a blank 42 having a front wide portion 421, a middle tapered portion 422, and a rear narrow portion 423, as in the rear, and at the same time as the front wide portion 421 A front aligning groove 424 is formed on the side surface, and a rear aligning groove 425 is formed on the side surface of the rear narrow portion 423. The diameter of the front wide portion 421 is larger than the diameter of the rear narrow portion 423 and the middle cone The diameter of the portion 422 is gradually reduced from the front wide portion 421 to the rear narrow portion 423. As for the arrangement of the front centering groove 424 and the rear centering groove 425, the alignment of the lower forging process is facilitated. The male mold 314 leaves the first female mold 3 12 toward the crucible, and passes the rough blank 42 out of the first female mold 312. Re-forging type: Referring to Fig. 4 and Fig. 6, the pinching device then the thick chain product 42 is turned upside down and inverted, and then sent to the second punching device 32, and placed in the first cavity 321 of the second female die 322, and the first half of the thick blank 42 protrudes out of the first cavity 321 'the same drive The second male mold 324 moves toward the second female mold 322' and drives the second punching rod 323 to punch the rough blank 42 to re-forge the rough blank 42 to form a flat and shaped outer shape. At the same time, a front groove 43 1 ' is recessed on the side surface of the release product 43 and a rear groove 432 is recessed on the rear side surface. It is thinned at a central portion 433 between the front groove 431 and the rear groove 432, which is favorable for the punching of the next forging process. In addition, the outer shape of the washer of the embodiment is an oblate shape. The second male die 324 exits the second female die 322' forward and passes the blank 43 out of the second female die 322. Punching forming: Referring to Figures 4 and 7, finally the pinch device will again 9 201036731 The release product 43 is sent to the third punching device 33, placed on the front side of the third female mold 332, and centered. The P position 433 S should be the through hole 331, and the third male mold 334 is driven to move toward the first female die 332. And driving the third punching bar milk to cut through the central portion 433' of the release product G such that the central portion 433 falls backward into the through hole 331, so that the release product 43 is formed into a washer with a perforation 51 Finished product 5. Thereafter, the third male mold 334 is driven to move away from the third female mold 332, and the cheese product 5 is separated from the forging apparatus 3 to be sent for output. Repeat the above steps to repeat the forging and production of the finished product 5 . Referring to FIG. 9, the steps of the second preferred embodiment of the manufacturing method of the present invention are substantially the same as those of the first embodiment, except that the forging apparatus 3 used in the embodiment further includes a shaping device 34. The integrator 34 includes an integral master mold having an integral mold cavity 341, and an integral male mold 344 having a - integral punch bar 343 and movable to move toward the integral female die 342. As shown in FIG. 8 , FIG. 9 and FIG. 10 , the manufacturing method of the embodiment of the present embodiment further comprises a de-edge shaping step after the step of intercepting the interesting material and before the step of roughing the initial forging. Step: using the pinch device to send the intercepted chain to the shaping device 34, inserting the integral mold hole 3 4 i... of the integral female mold (4) and driving the integral male mold 3 4 4帛The mold 3 4 2 moves to drive the integral punch bar 343 into the signing cavity (4), and at the same time, the W is trimmed to the shape, that is, the finishing (4) (four) 4 W is formed at the edge of the edge of the wire, so that the whole The post-type material 41 has a rounded portion 411 formed on one end of the periphery and having rounded corners, and a flush portion 412 formed at the other end and having a flat edge. Then, the driving type male mold is corrected to move forward away from the integral female 10 201036731 mold 342, and the finished material 41 is sent out to the integral female mold (4). Then, in the phase forging and roughing step, the pinching device will roll the inverted material into a first punching and forging device 31 and then perform the punching and forging to form the rough product 42. Then, the release product 43 is formed through the re-forging step, and finally the finished product 5 is completed in the punching and forming step. ◎ Ο Since this embodiment is used after the step of extracting the material, the outer shape of the material 41 is removed and the burrs are removed by the step of trimming, which can facilitate the subsequent forging to ensure that the shape is complete and that it is intercepted. Between the step of describing the material and the step of roughing the initial forging, and adding the step of finishing the edge, it is possible to delay the deformation speed of the material, so that the mechanical properties of the finished product 5 can be further enhanced. Referring to FIG. 11, the steps of the third preferred embodiment of the method of the present invention are the same as those of the first embodiment, except that the second forging device (10) is not used in the embodiment. The structure of the two master molds is changed slightly, so that in the step of re-forging, the rough product 42 is sent into the second punching device and then punched again, and then a flat portion is formed, and A release product of the protruding milk protruding from the center of the rear side of the flat portion 434, and a front groove 431 is recessed on the front side of the blank 43 and recessed on the side surface of the convex portion 435. A rear groove—the front groove is formed between the convex portion 435 and the central portion. Then, the prototype product u is sent to the third punching device (not shown), and when the punching forming step is performed, the third punching device will punch through the release product 43 < the central portion 433 and the convex portion In order to shape the prototype 43 into a mouth and a time with a perforated file. Since the release product formed in the embodiment has a protruding portion 435 on the rear side of the splicing portion 434, when the clip 11 201036731 is fed by a feeding device (not shown), the projection is extended. The portion 435 can be stably held to facilitate the transfer. In summary, the method for manufacturing the washer of the present invention is to add a step of initial forging and thickening between the step of cutting the chain and the step of re-forging. ^ After roughing 42, it becomes the prototype 43, so it can slow down the speed of material deformation', which can relatively improve the quality and mechanical properties of the finished product, and the thickness of the finished product 5 and the roundness of the outer diameter. It is easier to control than the sub-forging method, and in the present invention, the separate blanks 41 are sequentially forged in the respective punching and forging devices 31, 32, 33, respectively, or sequentially in the shaping device 34 and the respective punching and forging devices 31. Forging in 32, 33, respectively, because the cutting step is followed by the initial forging blank step and the re-forging step two forging process, and the impact force of the two punching is far less than the conventional one-time forging Force, so it is less likely to cause scratches and grinding of molds and fixtures The present invention can be used to achieve the purpose of the present invention. The scope of the invention, that is, the simple equivalent changes and modifications made by the invention in the scope of the invention and the description of the invention are still within the scope of the invention.
