The reason is that the drill tail: To: The strength of the rain is to drill through the iron plate and other materials, and the tail. Made of more material than the reference material, it will greatly increase the production of strong screws....: Cost, so there is a composite generation. * The manufacturing method of the composite screw is included. A preparation step, preparing a heavy iron The system does not record steel as the first base metal, and - one weight: = 8 () ~ 9_ Austin steel is the second base material, will be, the ratio of 10 to (four) of the carbon body, and; Forming a rod having a flat circumference opposite to the screw head to form a screw head, and one end of the rod body portion π 4 is formed as a drill tail portion, and wherein the second base material is formed The joint surface; the end of the bristles ^ is formed - a welding step opposite to the welding surface, the welding surface is joined with a composite screw; the mesh is welded to each other to form a finishing step, the composite material Μ removal, so that the itch joint is formed - the outer edge of the flat U joint is redundant, the drilling step Screw-machine-screw forming_, the rod body material is molded to at least - 201115038 screw to form a composite screw; the hardening step ' is to locally harden the drill tail of the composite screw to harden it ; and - surface treatment step 'surface treatment of the composite screw. The composite screw formed by the above steps is generally used for locking to a wooden or slab iron. However, the composite screw cannot be drilled through a non-recorded steel material, and thus is limited in use. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a method for manufacturing a composite screw which can improve the hardness of the drill tail portion. Therefore, the manufacturing method of the composite screw of the present invention comprises: a preparation step of preparing a first base material of a material of the Austin iron-based stainless steel and a second mother material of the material of the Ma Tian loose iron system. Material, the first base material is formed into a cup body having a flat circumference, and a screw head is formed on the rod body of the rod body, and a body of the body is opposite to the screw head. Forming a welding surface, the second female structure is formed from the mountain base material into a drill tail portion, and at the end of the drill tail portion, a joint surface with the joint surface (four) is formed, a welding step, The welding surface and the joint surface are welded to each other to form a composite screw blank; - a finishing step, the composite screw is used for the addition of the screw blank, and the circumference of the weld is more than 1 formed - flattened _ edge; Make the weld. - a film processing step, immersing the composite screw blank in the coating treatment agent of the LC for 1 to 6 minutes; and 201115038 a drilling tail forming step of the composite screw material after the soaking Drilling the tail forming; the wool-thread forming step 'forms the outer circumference of the rod body to at least the spiral ring to form a composite screw; the hardening step is the drilling tail 800 for the composite screw ~ ll 〇〇〇 c, 15 ~ 60 seconds of local heat treatment; and Ding a surface treatment step, the "screw surface for surface treatment.

The following is a clear description of the present invention with reference to the drawings. The foregoing and other technical contents, features and effects, in the detailed description of a preferred embodiment, can be compared with FIG. 2, the manufacturing method of the composite screw of the present invention is compared with the following steps: The welding step 22, a finishing, a film processing step 24, a drill tail formation; a step %, a hardening treatment step 27, and a surface treatment step ^ tooth forming step in the preparation step 21 towel, is prepared a material for the Austrian steel The first base metal 3, and one material is not "not base metal 4, 苴中," 脒 铁 铁 系 , , , , , , , , , 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻 麻The weight percentage of unrecorded steel is 10 to 20%. The first base metal 3 is formed by pressing one end of the rod to form a screw head ^ and the rod body portion 201115038 3! opposite to the end of the screw head 32 is formed with a welding surface %, material 4 One end of the joint surface is formed with a joint surface corresponding to the weld surface %. In the welding step 22, the weld surface 33 and the joint surface core are welded to each other to form a composite screw blank 5, which is made of a tanner. Direct heating is carried out. ΜStep 22 In the arranging step 23, 5 rows of the composite screw blank are added to the excess material of the periphery of the welded portion of the composite screw blank 5, which is commonly referred to as deburring, and the itch is etched. Forming a flat peripheral spear, in the film processing step 24, the composite screw blank is processed by a film of 7 〇 to 10 (10) t for (four) minutes. In the seventh embodiment, the film treatment agent is selected from a pH value. For 〇 ~ 3 acidic solvents. The molding step 25t' is to mold the drill tail portion 41 by the immersed composite screw blank drill forming machine (not shown), and the material of the drill tail portion 41 is special steel type-fine iron system. =, the recording steel 'causes the mold of the tail forming machine to be easily damaged during the tail forming molding. Therefore, the composite screw blank 5 is immersed in the film treating agent, so that the first base material 4 can be treated by the film treating agent. The acidity changes and a protective film is formed on the surface thereof. When the second base material 4 is processed and formed, the mold of the tail forming machine can be protected by a protective film on the surface thereof, that is, the falling: facing The loss of the mold of the tail forming machine can further extend its service life. to. In the snail forming step 26, the outer periphery of the rod portion 31 is formed into a screw-shaped thread 6 to form a composite screw 7. In the hardening treatment step 27, 8 to 110 CTC is applied to the drill tail portion 41 of the composite screw 7 by a high-frequency machine, and local heating is performed for 15 to 60 seconds to cure it. In the surface treatment step 28, the composite screw 7 is surface-treated. In this embodiment, the surface of the composite screw 7 is galvanized to beautify the surface of the composite screw 7, and other surface treatments may be used. The method can be easily replaced by those skilled in the art and will not be described here. With the above design, the manufacturing method of the composite screw of the present invention has the following advantages: (1) Wide application range: Since the composite screw 7 is made of granulated iron-based stainless steel as the material of the drill tail portion 41, In addition to the wood or iron plate, it can also be drilled with stainless steel, so it has a wide range of applications and high applicability. (2) Protect the mold of the tail forming machine: Because of the material of the drill tail 41 It is a non-ferrous iron in the field. Therefore, if the tail portion of the drill is directly formed by using a tail forming machine, the mold of the tail forming machine is easily damaged. Therefore, the composite screw 7 is first immersed in the coating treatment agent. Further drilling and forming can protect the mold of the tail forming machine, that is, reduce the loss of the mold of the tail forming machine, thereby prolonging its service life. As described above, the composite screw 7 manufactured by the method for manufacturing a composite screw of the present invention can be drilled through stainless steel, so that the application range is wide and the applicability is high, so that the object of the present invention can be achieved. However, the above is only a preferred embodiment of the present invention, and the scope of the invention may be limited by the meaning of the invention, that is, the simple equivalent change of the patent scope and the description of the invention in the present invention. And modifications are still within the scope of the invention.
