P 1 6 'at the same time, one end of the rod body is formed as a screw head 151, and 5; and a welding end 152 disposed opposite to the screw head 151; and 'one end of the tail section 16 of the 镨屋邹通钻钻Formed as a drill end 161 ' and the drill tail end 161 is provided with an engaging end 162 in the opposite direction, and the joint end ι 62 is convexly provided - a joint 163 ′ with the welded end 152 (four) and the joint piece 163 is convex A bump 16 5 having a flat surface 164 is provided. The cutting process is continued, and after the preparation of the river material is completed, the front end step 12 can be performed, that is, by the welding end 15 2 and the bump 16 5, the rod body consumption and the material portion 16 are combined with each other - Composite embryo = = = and as shown in Fig. 3, after that, the excess material of the composite blank 2 is removed by turning in the cutting step 丨3, and the state of Fig. 4 is formed, and finally the molding is performed. In step 14, the composite blank 2 is formed into a thread 21 by a tooth holding device (not shown) to form a composite material screw 3 shown in FIG. However, it has been found in the actual manufacturing process that it has the following defects, as detailed in, for example, 200902861 5 f' 10 15 Ο: 1·Because the rod body 15 is a fiber-optic tail 卩16 fresh joint, the welded end is 152 and the bump 丨 65 are frictionally joined to each other. In the welding process, the welded end 152 and the flat surface 164 of the bump 165 are mutually spun together, so that the fresh joint 4 is smoothly released, resulting in the smooth discharge. After the rod body portion ^ is welded to the drill tail portion η, the joint portion thereof is easily covered by the air to form a void, which affects the joint strength between the rod body portion 15 and the drill tail portion 16. Continuation of the description of the joint between the welded end 152 and the joint ^3 due to the two planes 'plus ± friction welding process must be Xiang Gao voltage matching. ' So the welding process is not easy to make the rod body 15 and the tail of the drill 16 mutual alignment, resulting in uncorrectable skew after welding, affecting manufacturing quality and yield, is also worth improving. [Summary of the Invention] Therefore, the "object of the present invention" is to provide a method for manufacturing a composite material screw' The invention reduces the occurrence of voids during welding, reduces the defect rate of bonding, and improves the manufacturing quality of the composite material screw. Thus, the manufacturing method of the composite material screw of the present invention sequentially includes a borrowing step, a welding step, a cutting step and molding. Step; wherein the preparing step has a rod body and a drill tail portion, and the rod body portion is formed with a flat welding surface, and the drill tail portion is provided with a pointed cone, and the tip cone has a tapered surface Therefore, in the welding process of the rod body and the drill tail, the design of the tip cone can be used to accurately and correctly control the rod body and the tail portion. In order to reduce the skew phenomenon after welding, and the welding process is reduced, the voids generated by the air coating are missing, so as to improve the manufacturing quality of the composite screw 20 200902861.
