Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for manufacturing a hexagonal anti-theft anti-loosening gasket, in particular to a hexagonal anti-theft according to which a high-low continuous wedge surface and a V-shaped groove and a pointed strip can be manufactured. The processing method of the anti-loose gasket. [Prior Art] According to the prior art, the patent No. 91914257 is a method for manufacturing a lock washer, which is used to manufacture a lock washer having a thickness variation, as shown in Fig. 1, which shows Before the strip (10) is rushed near the top and bottom edges: the corresponding guide hole (11) (step A), and the guide hole (丨丨) is used to guide the material f (10) stroke, and then The middle hole (12) residual groove (13, 14) is punched between the adjacent guide holes (u) (step B), and the middle hole (12) is located at the center of the material belt U〇), and the upper and lower residual grooves ( 13, 14) respectively located on the middle hole (12), between the upper and lower corresponding guide holes in the middle hole (12) toward the traveling direction-side: the fork-side residual groove (15) (step C), and On the other side of the middle hole (12), punch the other side of the groove between the holes (step D), so that the material (1〇) is the main body (16) of the hole (12) And the main system is forged by a four-legged (1°) top and bottom edge connection, and then by cold forging plus n it, a plurality of inclined faces arranged in a nesting manner (step by step) Make sure that it reaches the larger and i circle "" Then two more masters and two rushing to set up the anti-pine loose thickness of the manufacturing line 6 can provide manufacturing experience with experience, hair _ ^ still correct the township from the _ manufacturing of 1292002 1. The processing steps of the conventional technology tend to In the process of complexity, there are two empty itineraries. It is known to the general practitioners in related fields that each additional step requires an additional mold, which will undoubtedly increase the cost of the operator, and the cost will be added to the consumer. Therefore, By reducing one step, the cost of the operator can be relatively reduced. 2. The prior art technique is to forge a plurality of radially arranged inclined faces on the top surface of the main body, and then proceed to the next precision forging step to achieve the required size. However, when the main body is forged to form an inclined surface, its contour will be deformed or even slightly offset. Therefore, in the case where the main body is not well positioned, it is easy to cause the mold to be crushed at the oblique angle during the precision forging process, which is not ideal. · Furthermore, the conventional technology of the tripod (17) supports the design of the main body, because the position of the tripod is just at the lowest thickness of the inclined surface, so the remaining material at the lowest thickness is nowhere to expand, and then pushes Distortions caused by the main frame of the negative phenomena affect the success rate of subsequent machining molding engage daughter.
