[Prior Art] See Figure 1 A conventional method of using the method of J, which uses a punch (not shown) to punch out a majority of the finished product U on a sheet of metal 1, the manufacturing step of which is to prepare a sheet of metal of a predetermined thickness. Then, the metal plate i is sent to the punching machine to directly cut out the hollow ring-shaped finished product 11 on the metal! However, since the metal plate i passes through the blanking process, it will remain in the periphery of the finished product U of the company. The remaining material 12, the formation of a large amount of waste caused the wave f'i its ItiiJ Huasi finished u's mechanical strength is not good, the peripheral shear section is sharper, the product quality is low, so its preparation still needs to be improved. See Figure 2 Another method of manufacturing the conventional method 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, a clamp 212, and a hollow Mother die 213 'and one The male mold 215 having a punch bar 214 is in the following description with the upper side of the drawing as the front side and the towel as the rear side of the drawing surface. The manufacturing method of the washer comprises the following steps: (a) pinching the feed. The wire 22 is fed into the feeding base 211, and then the wire 22 passing through the feeding base 2n is clamped into the female mold by the clamp 212, and is advanced to extend the female mold 211 for a length, so that the wire 22 is divided into a female mold 211. The inner clamping section 221 and a working section 222 protruding from the female die 2 ι. 3 1358334 (b) Initial forging type: the driving male mold 215 is moved backward toward the female die 2i3, and the punching protrudes from the female die. The working section 222 of 213, the working section 222 is initially forged into a flat product 223 having a desired thickness and shape. (c) Re-forging: then driving the punching rod 214 located in the center of the male mold 215 Punching the central part of the release 223, and pushing the clamping section back a distance, to punch a perforation in the center of the prototype 223, so that it is shaped into a finished product 23, and at the same time make it The pinch section 221 is separated. (d) Finally, the driving male mold 215 is moved forward to the mother die 213 and moved back to the original position. The finished product 23 is separated from the forging equipment 21 for output. The above steps can be repeated for forging production. Although the above-mentioned heating method can be cold forged, the wire 22 is forged into a finished product 23, but it is composed of the above (a Step (b), the working section 222 in the shape of a round rod is forged into an oblate shape 223 only after one swaging, and the material deformation amount is large, which will result in the finished 232 finished product. The mechanical properties are not good. Moreover, since it is directly cold stamped on the wire 22, the working section 222 is connected to the rear pinch section 221, and the clamp 212 and the feeding seat 211 are clamped to the pinch section 221, so During the forging process, both the clamp 212 and the feed base 211 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. And in the re-forging step, the punching rod 214 is required to push the rear connected pinch section 221 while punching the perforation, so that the Huashi product 23 is separated from the pinch section 221, and the punching force phase required for this step is required. The large size will shorten the service life of the mold and fixture, which not only affects the accuracy of the clamping feed, increases the defect rate, and causes the cost loss that is difficult to ignore. 4 and when the forging equipment 21 is shut down, it will also This makes the high-speed mass production work stop, resulting in reduced production and poor production efficiency.

The stencil 43 of the 435 is simultaneously recessed to form a front concave 431 on the front side of the release 43 and recessed to form a rear recess 432 on the rear side of the protruding portion 435. The front recess 'n and the extension A central portion 433 is formed between the portions 435. Then, the prototype a is sent to the third punching device (not shown), and when the punching step is performed, the third punching device punches through the central portion 433 and the protruding portion of the release 43 The portion 435 is formed so that the prototype 43 is formed into a finished product 5 having a perforation 51. The release 43 formed by the embodiment is attached to the flat portion 434 having a Watts shape. It is provided with a protruding milk, so when it is used to secure the pinching device (not shown) at the time of the loss of 11 1358334 435, it is held at the protruding portion to facilitate the transfer. In summary, the manufacturing method of the present invention is to add a preliminary forging blank step between the step of cutting the picking and the step of re-forging, so that the blank 4 is passed through the thick I 42 to become the prototype 43 . Therefore, the speed of material deformation can be slowed down, and the quality and mechanical properties of the finished product can be relatively improved, and the thickness of the finished product 5 and the roundness of the external kneading degree are easier to control than the conventional forging method. According to the present invention, the independent (four) 41 is sequentially forged in each of the punching and forging devices i 31, 32, and 33 t, or sequentially forged by the shaping device 34 and each of the punching and forging devices 31'32 and 33 respectively. After the material step, the initial forging rough step and the re-forging step are two times of the forging process, and the impact force of the two punching and forging is far less than the force of the conventional one-time forging, so it is less likely to cause scratches on the mold and the fixture. With the wear, the loss of the forging equipment can be reduced, and the service life can be prolonged, so that the object of the present invention can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
