Description of the Invention: [Technical Field] The present invention relates to a method for forming a loop (or nut), and more particularly to a method for forming a chipless washer (or nut). [Prior Art] The difference between the 'washer and the nut' is that the thickness of the nut is thicker and the thickness of the washer is thinner. A through hole is formed in the middle of the nut, but the nut is opened on the through hole when the nut is finally processed. There are threads, so the shape is much the same; only the difference in machining is the size of the washer molding machine, so it is mentioned here. The following is only an example of the gasket molding method. In the process of the traditional gasket, the metal steel plate material is used, and the punching is performed by a general punch press forming machine, so that the gasket is forged into a standard, and a large amount of waste is generated after the ring is formed, resulting in the manufacturing cost of the ring. Although the waste can be recycled, the recycling price is limited, and it is still difficult to effectively offset the high manufacturing cost. Referring to FIG. 1 and FIG. 2, there is another stamping forming method j, which comprises a preparation step 11, a feeding step 12 and a stamping forming step 13 and the like; wherein, in the preparing step 11, a metal material is prepared. The wire 2; in addition, the feeding step 12 has a machine table 121, a mold 122 disposed on the machine table 121 and having a feeding hole 123, so that the wire 2 can pass through the feeding hole 123 and The punching and forming step 13 is provided with a pair of punching seats 131 disposed on the die 122, and a punching block disposed on the punching seat 131 for performing the protruding action 132. 201242687 Referring to FIG. 2, FIG. 3', after the wire 2 is fed through the feeding hole 123 in the process, it is clamped and fixed by the mold 122, and protrudes - the preset length is on the mold (2), and the punching The seat 131 performs the first press for the wire 2 on the (four) 122, so that the wire 2 is expanded and formed by the first knitting, and the outer diameter of the wire 2 is larger than the feeding hole 123, and then the second pressing is performed. Forming the prototype body as a predetermined size of the loop 3, and finally performing the forming process of the gasket 3, and when the stamping seat 131 and the mold 122 press the gasket 3, The punching rod 132 on the seat 131 has a reciprocating displacement action, so that the punching column 132 performs an impact operation on the center portion of the washer 3 to reduce the center portion into the human material hole 123, so that (4) A through hole 31' is formed in the ring 3, and the wire 2 is separated from the gasket 3 formed on the mold 122 by the squeezing action of the feed hole 123 and the punching rod, thereby forming the desired gasket 3. Finished product. In the molding process of the inspection method of the knowledge circle of the province, although the required gasket 3 can be formed for use, there are still the following defects in the actual molding, which are detailed as follows: 1. Cloud in the mold 122 is - the design of the plane, and no coverings for the support, so whenever the wire 2 is subjected to the considerable impact of the stamping seat 131, the wire 2 will be expanded again and again, and the stamping process is not only cumbersome Moreover, it is time consuming, and the wear of the mold 122 and the stamping seat 131 is more likely to be caused, and the size of the gasket 3 can not be effectively controlled to be within a preset range, so that the gaskets 3 after the press forming will have different sizes. The situation. 5 201242687 2. Continued above the above-mentioned phenomenon of perforation 31 after the completion of stamping, it is easy to present burrs, etc., so that the gasket 3 needs to be further added with a deburring operation procedure, so that not only will the cost increase be increased. There will still be waste generated after processing, which needs to be improved. 3. Furthermore, the wire 2 is clamped by a single die 122, and the clamping force is limited, and the wire 2 is easily subjected to stamping, which causes the wire 2 to be easily returned, thereby causing the gasket 3 to be formed poorly. Moreover, even because of the wire material returning relationship, the wire 2 is swollen and squeezed into the mold 122, so the mold 122 must be disassembled and repaired, which makes subsequent maintenance more inconvenient.

Further, the push-stepping step 44 is provided with a pushing device 441 (shown schematically in the drawing), which is formed for the aforementioned steps. The body 5 is moved from the fixed mold 423 to the opposite position of the molding die 424, and a beating device 442 (shown in a simplified manner) is additionally provided on the side of the molding die 424. The sculpt 442 can push the prototype body 51 pushed by the ejector device 441 into the molding die 424 to facilitate subsequent stamping of the second die 432. Furthermore, the forming step 45 has a stripping device 451 (shown schematically in the figure) disposed after the forming die 424, and the blank body 51 is punched by the second die 432 to make the prototype body A gasket 6 (or a nut) finished product is formed in the molding die BB and the gasket 6 (or nut) is withdrawn from the molding die 424 by the stripping device 451. Referring to FIG. 3 and FIG. 5 to FIG. 6 , in the forming process, in the preparation step 201242687 step 41, the wire 5 having the metal material is prepared, and the wire 5 is advanced and protruded by a predetermined length in the fixing mold. After the position 423, the wire 5 is clamped and positioned by the solid cooker 423 and the clamping device 422, respectively, and the fixed mold 423 clamps the axis line of the wire 5, and is clamped with the clamping device 422. The axis line α of the wire 5 is not on the same axis (ie, the feeding step 42), thereby ensuring that under the pressing action of the first die 431, the wire 5 does not form a displacement retreat state due to the instantaneous force generated. In this way, the wire 5 is caused to smoothly expand in the preliminary cavity by the impact force of the first die 431, thereby forming a prototype body 51 having the through hole 51 (ie, the punching step 43). After the first die 431 is withdrawn from the fixed mold 422, the wire 5 is no longer clamped by the clamping device 422, so that the prototype body 51 is subjected to the wire to be protruded at the fixing die 423. 5 pushes the top and protrudes out, and at the same time pushes The material device 441 pushes the prototype body 51 from the fixed mold 423 to the molding die 424 and pushes the prototype body 51 into the molding die 424 by the beater 442 (ie, the pushing step 44), and then The second die 432 performs a punching elimination action on the burr formed on the periphery of the perforation 52, and eliminates the burr in a stamping manner without waste generation, and also contributes to the formation of the leading and circumferential faces of the peripheral surface of the prototype body 51. So that the release body 51 forms a gasket 6 (or nut) in the molding cavity B, and finally the gasket 6 (or nut) is withdrawn from the molding die 424 by the stripping device (ie, molding step 45) 'In this way, the molding operation of the gasket 6 (or the nut) is completed. From the above description, it can be known that the present invention has the effect of improving 201242687 in the molding method. The following is summarized as follows: 1. The design of the fixed die cutting of the stamping step 43 ensures that the prototype body 51 formed by the punching of the first die 431 can be controlled to the size of the preliminary cavity A. Same, not different in size [Effectively improve the production quality. 2. Continued above, the prototype body 5i after completion of the stamping step 43 can be directly conveyed to the forming step 45 by the pushing device 441 in the pushing step 44. On the mold 424, the punching action of the burr is performed, and the process of eliminating the burrs is eliminated without the waste material, which will shorten the time of the industry, and the processing cost required for the I can be effectively reduced. In view of the fact that the wire 5 is effectively preliminarily clamped by the fixed mold 423 after being fed, it can be further clamped by the clamping device 422, so that under the double effective clamping, the The wire 5 is prevented from being displaced by an instantaneous pressing force, and the wire 5 can be punched into a blank body 51 having the through hole 52 at a time, and at the same time, the wire 5 can be prevented from being swollen and squeezed when displaced. The situation in the mold 423 is fixed to ensure the smoothness of the work. In summary, the method for forming a chipless gasket (or nut) of the present invention is effective in one stamping process by a consistent process such as a preparation step, a feeding step, a stamping step, a pushing step, and a forming step. Rapid prototyping not only shortens the stamping process, but also makes the wire fully utilized in the stamping process without any waste, which effectively reduces the cost, so it is true that the moon I achieves the purpose of the present invention. The above is only a description of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes made according to the scope of the invention and the contents of the description of the invention. And the repair, should still be within the scope of the invention patent.
