In particular, a variety of materials [prior art] Referring to Figure 1 and Figure 2, the different materials include a preparation step u, welding (four) 12, =, = manufacturing method, step 14 and the like; wherein the preparation step U is two =13 and the forming step is divided into one body 15 and one tail 16, _ kind;; = the base material is formed into a - screw head (5), and a opposite to the screw = body 15 - end welding end 152 丨, > ", one end of the buckle 16 disposed in the direction of 151 is formed - and continues the foregoing, # the foregoing material is prepared ^ 62. The end 152 and the joint end 162 13 can be welded for the welding of the shaft 15 and the core welding step 12 So that after the second, the second, the composite billet 2 shown in Figure 3, and then, the second step by the cutting step will be the excess =: 4:: state, and finally TM step two: Drill: part 21 ' and use the gingival equipment (not shown in Fig. 5, which is shown in Figure 5, that is, the manufacture of the screw 2 is completed. The standard manufacturing process found that it has the following missing, as detailed below: I Since it is known that welding must be used, the fusion process cannot control the artificial welding quality of the welding, except that it affects the shaft and Tail _ quality, and the shaft and the tail after welding are prone to skew, affecting the manufacturing quality and yield. 20 1311933 •5 ❿ 10 15 20 2.=The shaft and the tail are formed by the fresh joint-composite embryo After the material, the area is imaginary, and the high temperature during welding (4) causes the fresh joint-k and the material hardening phenomenon to cause difficulty in the subsequent drilling and thread forming process. 3_==The splicing of the material will also produce the residual material. Therefore, it is necessary to remove the molding step after the cutting step, so that it is not only costly and increases the cost. [Invention] The purpose of (4) is to provide a cage of different materials. In the process of the production process, the cost reduction and the improvement of the manufacturing quality are achieved. Thus, the manufacturing method of the composite material screw of the present invention comprises a preparation step, a joining step, a stamping step and a forming step, respectively, wherein 誃=step Dividing two different materials into a shaft and a tail, and; forming a first and second joints on the body and the tail respectively; and, the engaging step is the first and second joints title Correspondingly, the card is fixed to open the composite billet which is initially connected to the stem and the tail end; further, the stamping step is on the outer periphery of the composite billet and is connected with respect to the first and second ends. Pressing at the P position to preliminarily position the shaft and the tail; at the most, the forming step is to perform the tail forming and the threading of the composite blank, and the thread is formed during the forming process of the screw The first and second connecting 4 card positioning positions may be squeezed to form a first and second connecting portion positioning and more compact screw '· is 'the first and second connecting parts are positioned first After the 'combination with the punching step in the first step of the stamping position' to form - preliminary joint 5 1311933 .5 10 15 20 knot composite billet, and finally through the screw teeth to form a good quality of different material screws, greatly simplifying the knowledge Add: Process, and further improve the hardening phenomenon of the material produced in the process of knowing the fresh joint, and it is not easy to be processed and lost, so as to reduce the manufacturing cost. The above and other technical contents, features, and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments.牌牌,月走 Before the present invention is described in detail, it is noted that similar elements are denoted by the same reference numerals. Referring to FIG. 6, a manufacturing method 3 of a first preferred embodiment of the present invention mainly comprises (4) (4) 31, a stamping step 33, and a forming step 34, which are not π = see FIG. 7', and the preparation step 31 has two different materials. "Taiyi" is - shaft 41 and - tail 46; wherein the shaft 41 has this::: the middle is not _ material, the shaft has two snails 42 盥 first you pull, η and Shi In the example, the first connecting portion 43 may be in the form of a groove 431 ′ of the present plum blossom, or the groove 431 may be a shaped shape, a square column type or a multi-dimensional square column type. Concave the Chuanjiao corner 1 trough body, etc., and the following examples are all described in the groove 431 of Dui. The corpse 4 tail 46 is a carbon steel material in this embodiment, and Shoucai 曰 = one end is formed The second connecting portion 47 and the end surface 2: may be - the studs * the following embodiments are both hereinafter and the one side of the stud 471 is formed - the free end 'in the following description 'the different material screw engagement step 32, 6 1311933 Referring to Figure 6 and Figure 8, the manufacturing process... In step 31, the body 4] and the rod are first prepared by the preparation step 32, that is, the groove 4 is ordered. The step is inserted into the groove heart ^ Μ and the tail end 46 of the first fish strong card I position, thereby forming the composite body turn 5G of the shaft step 33 (four); and then the punching step and the outer step are simultaneously shown in FIG. It is attached to the county of the composite blank and is connected to the groove 471 with respect to the protrusion 471 to make the composite blank 5. The plurality of enamels are formed on the surface; The sowing pressure, so that the rod: can be completed to reduce the joint, so it is not necessary to use the high energy-consuming glow to form the initial positioning joint of the dry body 41 and the tail 46, except for 15 minus; =, and reduce the conventional person In addition, the welding error occurs, and more: avoiding the hardening of the material during the fresh joint process, resulting in subsequent processing difficulties. Continued to refer to Figures 6 and 10, and finally the molding step is performed, after the material = step 33 is completed. The composite blank 5Q performs the molding of the tail 5, and the screw 52 is formed by using a dental caries (not shown in the figure: the desired screw 52 is formed by rolling, and the composite blank 5 is formed. The overlap between the second and the second joints (not shown in the figure) is more tightly combined when the pressure is applied to complete the reality. Different examples: the manufacture greatly eliminates the unnecessary flux after the traditional welding and the cutting operation, and avoids the obstacle caused by the molding step 34, and can avoid the shaft caused by the welding. The composite blank 50 formed by the tail insertion device 7 5 10 15 1311933 produces a skewed condition, and the smooth and normal operation of the type step 34 ensures the success of the screw 52 and reduces the production cost. Referring to Figure 11, the second preferred embodiment of the present invention differs in that: ''" and its first-protrusion portion 6 can be a stud 6 and the tail 46 The second energy sample, Ganshan 4' is - groove 62, wherein the protrusion 6i can be a groove 62 shape as a card locating to match the concave step 'this' regardless of the subsequent connection step 32, the stamping step 33 and outside the town, even after assembly, Yuancheng Bu / etc. are the same as the first embodiment 、 2, the same in the 疋 position, etc., will not be detailed. :Reading the picture! 2' The third preferred embodiment of the present invention, regardless of the foregoing first, Le Yi: Τ 例 任 任 任 任 任 任 任 任 任 任 任 任 任 任 任 ^ ^ ^ ^ ^ 本 本 本 本 本 本 本 本 本 本 本 本 471 471 471 The damper portion 49 is also formed in a timely manner. In order to facilitate the following description, the first embodiment is described as an example, that is, the dam portion 49 can be as a plurality of bumps in the embodiment. And each of the bumps has a top surface 491 ' of the far-free end 472 and a slope 492 extending from the top surface 491 toward the free end 472 and extending to the surface of the stud 471; The bump 490 is designed such that when the studs 47 浔 , n are inserted into the groove 431 for the first time in the joining process, the shaft 4 bristles 46 are tightly joined to form a preliminary joint. In order to make the process smoother and not fall off, and finally, during the extrusion process of the tooth (i.e., the molding step 34), the portion of the shaft 41 will cause the protrusion 471 to make the D-body cup. 41 and the tail end 4 6 form a different material screw 5 which is more tightly connected. 20 •5
