The present invention is mainly based on the design of the ratcheting method 20, which is shown in FIG. 2, wherein the steps include: preform 21: that is, the outer portion and the inner portion of the ratchet 10 After forming, 'form an initial embryo 30', please match the figure shown in Fig. 3, wherein the initial embryo has no tooth shape or other structure, and the inner diameter has formed the tilting portion 11 Forming margin ring groove 22: a margin ring groove 31 having a width slightly smaller than the width of the formed ring groove 14 is formed in a region between the predetermined shape of the ratchet tooth 13 and the limit ring 15, and the margin ring groove is formed. An oblique portion 31 () is formed at an end portion of the ratchet tooth 13 with respect to the end portion of the ratchet tooth 13, and the oblique portion 310 is obliquely extended to the bottom of the tooth by a predetermined ratchet tooth 13 and a ratchet is arranged at the oblique portion 310. The bottom of the tooth bottom 13 further forms a stepped falling portion 311, and the bottom of the falling portion 311 is adjacent to a flat groove bottom 312. The other end of the groove bottom 312 forms a straight wall 313, and the straight wall 313 is The drop portion 311 is slightly smaller than the width of the preset ring groove 丨4. Molded tooth shape 23: The initial embryo 3 having the margin ring groove 31 is manufactured by a tooth shape, and the manufacturing method is as shown in the first marriage, and the fine-knife is forged or sharpened or punched 'will be redundant The material formed more or less shaped swarf 5 (), or cut or moved to the primordial ring of the embryo, ah push the pure knife _ the power group can be set - feel the position 'When When the knives of the knives to the slanting portion 31 of the ring 31 are ,, the resistance becomes small instantaneously. At this time, the speed of pushing the knives is reduced and the force can be relatively weakened. The knives reach the inclination of the oblique portion (10). At the bottom of the bottom, and beyond the drop portion 3 (four), it is not necessary to make the scalper machine _, the more squad type swarf 5 〇 6 1374073 cut to the bottom of the groove 3! 2; or as shown in Figure 5 Rolling or hobbing the surface of the priming head 30 by a knife die 6 to form a ratchet tooth 〖3, and the height of the squeezing is the bottom of the slanting portion 310 to the margin ring groove 3 Adjacent to the falling portion 311, the extruded swarf 50 can be inserted into the falling portion 311 and the groove bottom 312 of the margin ring groove 31 without causing stress concentration. Integer 24: After the ratchet tooth 13 is formed, the final shaping operation of the shape portion can be performed, and the molded tooth lion is removed, and the lead angle of the ratchet tooth and the neck 12 and the ring are obtained. The groove 14 is completed; 25: The shape of the entire outer portion of the ratchet 10 can be completed. The method for manufacturing the ratchet teeth 13 after pre-forming the margin ring 31 of the ratchet 10 can effectively achieve the following functions, including: accommodating and eliminating stress concentration, 1 'secret system Unnecessary stress concentration during the toothing: when the ratchet 13 is manufactured, _ or forging or rolling or other processing methods, and excess molded swarf 50 can be generated into the margin ring groove 31. It does not destroy the purpose of the structure of the ratchet 10 as a whole. 2 can become the guard stroke control _ effective warning: by the sensor's match 'make the knife mold 4 〇 between the travel can monitor the line only with the angle ring ^ diagonal portion 31G sensed, It is achieved by different positions = resistance ^, and senses and reflects different travel speeds to achieve the best demand for reinforcement in the "workforce". 1374073 BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view of a ratchet structure of the present invention.
