Description of the invention: [Technical field to which the invention belongs] The wrench type has no ratcheting method and its structure, especially the type of ratchet used for the == configuration, because the ratchet is pre-formed on the embryo Read to achieve smooth processing and integrity after processing. [Prior Art] ❿ 1 According to the ratchet wheel in the head of the previous wrench, the processing method, that is, the method of the 12th preface "the method of making the wheel" is to form the ratchet by casting, and the other is provided with metal processing. In part, the processing of the ratchet shape is based on the completion of the inner diameter of the ratchet, that is, the milling of the miscellaneous reading shape. In this way, the surface dental milling method is simple to make the shape dental, which is easy to overshoot. Can not effectively cut the metal shavings in the same 4 of the construction, and cause the destruction of the ratchet surface. 'Even even the village can cause the stress caused by the marriage, the money is damaged by invisibility, the user and the processor all We know that, while waiting for subsequent processing or use, it is necessary to test the unnecessary damage, so there is a need for improvement. Another example is No. 592903, which can make a ratcheting method of 90 to 18 molars, which is formed after the inner diameter of the ratchet is completed, and the external tooth shape is directly formed by the method of no chipping, although it is a non-squeezing type. Forming, the accumulation of materials, but the so-called type, still due to the overall material of the ratchet, and there is no effective way to eliminate the lack of stress concentration caused by the extrusion material - even the squeeze, still can not have (4) The flow direction of the material, and destroying the strength of the material and the material female, there are also missing. 201024040 [Summary of the Invention] In view of this, the inventor of this case has carefully studied and accumulated many years of experience in the development of various wrench-related parts and shouting products and technologies, and finally developed a method for uncapped ratchet shape and structure. The object of the present invention is to provide a method for manufacturing a non-capped ratchet shape and a structure thereof, and a pre-forming a margin ring groove at a shape other than a ratchet initial embryo, by which the outer ring shape of the ratchet is set During processing, whether it is a redundant genus or extruded material, it can be discharged from the original position without causing concentration of stress, and an early warning of the end of the processing stroke can be provided to effectively stop the tooth shape from being added quickly, without adding It is the only one that hurts other structures' or has no processing, and (4) the purpose of producing crushing stress and effective processing. EMBODIMENT OF THE INVENTION The present invention has been made in view of the above objects, the technical and technical means, the other embodiments of the present invention, the preferred embodiments, and the detailed description of the drawings. The advantages, when it can be obtained from the frequency of understanding, but this is not the case, let us explain it. According to the structure of the ratchet 10 of the general wrench, as shown in the figure i, the outer portion of the ratchet K except for the hollow palm portion 11 includes a neck portion 12 having a smaller outer diameter. Immediately after the _12 ring is provided with a ratchet with a fixed tooth height, the ratchet wheel without sealing is 1_, the other end of the ratchet wheel ratchet dragon is formed into a ring groove for the C buckle, and the ring is another The end is formed - the limit of the thickness of the meat is limited, in order to limit the 201024040, the C buckle in the ring groove 14 does not escape. The present invention is mainly applied to the design of the ratcheting method, which is shown in Fig. 2, wherein the steps include: preform 21: that is, the external and internal turbulence of the ratchet 1〇 Part I: After forming, the shape of the initial embryo 3 is formed, please match the figure shown in Fig. 3, wherein the shape of the initial embryo is not toothed or other structure, and the inner diameter has been formed. The molding margin ring 22: in the region between the predetermined shape of the ratchet tooth 13 and the limiting ring 15, a margin width slightly smaller than the width of the ring groove 14 after forming is provided, and * The angled range 31 is opposite to the end of the set ratchet (4) - the oblique portion 31, which is obliquely extended from the pre-twisted ratchet teeth 13 toward the bottom of the tooth, and at the oblique portion 310 The end portion of the tooth bottom of the ratchet tooth 13 is predetermined to be formed again, and the bottom portion of the bottom portion of the bottom portion 312 forms a straight wall 313, and the straight wall 313 is formed. The drop portion 311 is slightly smaller than the width of the preset ring groove 14. Molded tooth shape 23: The priming head 30 having the margin ring groove 31 is manufactured in a tooth shape. The manufacturing method is as shown in Fig. 4, and is forged or sharpened or punched with a die 4'. The material of the evening will be more or less shaped swarf, or cut or pushed into the lion of the Na 30, and the __ knife mold power group can be another, and there is a sense of When the knife mold is applied to the thin oblique portion of the margin ring, the resistance momentarily becomes smaller. At this time, the speed of the knife die is reduced and the force can be relatively weakened. The mode cutter 40 reaches the oblique portion 31. When the bottom of the skew is at the bottom of the skew, the falling of the shaped swarf 311 can be surely cut off, and the formed swarf 6 201024040 can be cut to the bottom 312; or as in the fifth As shown in the figure, the surface of the initial embryo 3 is rolled or hobbed by a cutter die 60 to form a ratchet tooth 13, and the height of the extrusion is the oblique portion 31 of the Weiwei fine. The bribe difference portion 311 is stopped, so that the formed face can be squeezed into the falling portion 311 and the groove bottom 312 of the margin ring groove 31 without being in the state of making the silk scarf; 4: After the ratchet teeth 13 are formed, the final shaping operation of the shape portion can be performed. 'Excess molding chips 5G are removed, and the lead angle of the ratchet teeth 13 and the neck 12 and the ring are formed. The groove 14 is; 7L is 25. The shape of the entire outer surface of the ratchet 1 can be completed. The method of manufacturing the ratchet teeth 13 after pre-forming the margin ring 31 of the ratchet 10 can effectively achieve the following functions, including: 1 not causing unnecessary stress concentration during tooth making : When the ratchet teeth 13 are manufactured, or are cut or forged or rolled or other processing methods, the excess molded swarf 50 can be produced and placed in the margin ring groove 31 and the stress is removed. The needle can be used without destroying the structure of the ratchet 10 as a whole. 2. It can be an effective warning for the processing stroke control: the position of the stroke can be monitored by the matching of the sensor, and the stroke position can be monitored and matched with the oblique portion 31 of the margin ring 31 to achieve the borrowing The difference in resistance is generated by the difference in position, and the different travel speeds and processing forces are sensed and reflected to achieve the best processing demand. In the secret, the tree in the case reveals that there is no cover-stab. In the case of silky y-sex, it should be placed and its structure, in the invention of the case _ technical features, other than that, in addition, It has not been made public, and it has been seen in the magazines, and, /, has the fact that the above-mentioned effects have been enhanced. The _"_sex" and "progressive" are the county-specific regulations. Eight proposed invention patents please 'pray for review and early call for patents, real sense 201024040 [simple description of the diagram] The i-th diagram is a schematic diagram of the ratchet structure of the present invention.
