Description of the Invention: [Technical Field] The present invention relates to a profiled metal pipe forming machine and a molding method thereof, and more particularly to a spiral groove and a shape roll for a metal pipe by using a number of roller devices and a plurality of modules The processing of the system is based on the technical field of artistic styling. [Prior Art] According to the stainless steel metal and cast iron doors and windows, the 'bars have become the building materials commonly used in buildings. The metal rods of the basic materials are durable and can not be easily damaged by others', so they are widely used by construction companies. use. However, since the metal rods implemented in the doors and windows must be assembled into doors and windows to form a protective effect, the amount required is large, but the solid steel, solid cast iron or flat iron used as materials is not only cumbersome, but also wastes materials. Moreover, it is bent by a tool, and it is necessary to use a large machine to bend the steel during processing. This is not only time-consuming and laborious, but also when the steel is folded, the inner edge of the bend will be Inwardly concave, and the outer edge and the side portions of the sides are outwardly convex due to the force; therefore, in order to improve the above disadvantages, the industry has a hollow circular metal pipe as the material of the rod, but this Although the tube body can save the Lu material, when it is bent by the tool, the tube body will have a cylindrical shape, and the tube body will have a wrinkle of the protrusion on the inner side of the bend, or an inward condensation deformation. The reason is that the structural strength is insufficient, and because the hole diameter of the pipe body is large, it is impossible to make a more sensitive and delicate shape', so that the door and window and the bar decoration flower cannot be made more diverse. 】 In this case, the inventor of this case has To explain the current situation of the users, in order to solve the lack of the above-mentioned practitioners, first of all, if we can innovate the hollow type of circular tube Zhao in the construction, so that it has both light weight, enhanced structural strength and achievable appearance. 1330111 The advantages of versatility can solve the lack of metal pipe body of conventional building materials; in this direction, the inventors have found that if the outer wall of the pipe body is processed first, it has spiral indentation, and then it is processed to reach the predetermined pipe body. The shape of the section can combine strength and aesthetics, and facilitate the implementation of various subsequent doors and windows, masts and flowers. The invention relates to a molding machine for designing a special-shaped metal pipe, which comprises at least a spiral roller unit and a special-shaped pipe forming unit; wherein the spiral roller unit has an inlet end and a discharge port through which the metal pipe of the hollow pipe body passes. And at the outlet end, there are a plurality of roller devices capable of rolling the outer wall of the pipe into a spiral concave groove; the roller device can be pressed by the power source to sequentially press the outer wall of the pipe body - Spring processing to achieve spiral indentation. The shaped pipe forming unit comprises at least a gear set, a power source for rotating the gear set, and a plurality of modules with upper and lower molds, and the gear set can interlock the plurality of modules, and the number of modules is progressive The tube body is axially rolled at different depths to achieve a predetermined cross-sectional shape. Wherein, the metal pipe is disposed between the upper and lower molds of the module of the special-shaped pipe forming unit, and the corresponding faces of the upper and lower molds respectively have a bearing portion, and the protruding portions of the upper and lower molds are sequentially arranged. From the shallow to the deep, the number of modules is progressively rolled into the metal pipe body having the spiral concave groove on the outer wall. The molding method of the present invention comprises the following steps: '# spiral Recessed processing: The outer wall of the metal pipe of the hollow pipe body is processed to have a spiral indentation by a number of roller devices. Shape processing: The metal pipe with spiral indentation is subjected to progressive axial rolling by means of a plurality of modules of upper and lower molds, and the shape of the predetermined pipe body is made from shallow to deep pressure. The purpose of the present invention is to achieve the convenience of light weight, and the metal pipe of the hollow pipe body is first processed as a spiral concave groove, and then rolled into a predetermined sectional shape, and adopting a progressive type. The axial rolling method prevents the metal pipe from being deformed during the processing process and can accurately reach the shape of the predetermined pipe section; thus, not only the structural strength thereof but also the different artistic structure can be adapted. More 6 1330111 has a three-dimensional beauty, while reducing the waste of metal pipe, the excellent. [Embodiment] Please refer to the first and second figures, which is an embodiment of the profiled metal pipe machine of the present invention, which mainly comprises a spiral roller unit i and a unit 2; wherein, the spiral The roller unit is disposed on a working dust station 1 1 having a metal pipe through which the hollow pipe body a is provided; and an outlet end ί3, and at the outlet end 13 is provided with the pipe body a Outside = Rolling spiral indentation a 1 number of roller device 4, and each roller device Η - power source Ρ (such as the first picture) can be used to sequentially roll the outer wall of the pipe body a to achieve A spiral indentation is required. Please refer to the second and third figures. The shaped tube forming unit 2 includes a gear set 2 1 , a power source for providing rotation of the gear set 21 (not shown), and a plurality of upper molds 2 2 1 and lower molds. 22 2 module 2 2, and gear set 2 multiple gears 2 ! i, adjacent gears 2 i-worked and combined with the amount of 2 2 'the upper mold 2 2 1 and the lower mold 2 2 2 are reversed scroll. Please refer to the first, fourth and fifth figures' between the upper and lower molds 22 1 and 222 for the pipe body a to be pierced, and the upper and lower molds 2 2 1 and 2 2 2 for the corresponding faces of the pressure bearing portion 2 2 3 'and the degree of protrusion of the pressure receiving portion 2 2 3 is from shallow to deep (see the fifth figure) 'the upper mold 2 2 1 and the lower mold 2 2 2 of the module 2 2 may be the opposite body a for a certain degree of axial rolling, and adopting the progressive rolling method, the design is to progressively roll axially on the pipe body a by a plurality of modules 2 2 , as shown in the fifth figure, the body a An enlarged view of the portion of the shape structure through which the upper mold 2 2 1 and the lower mold 2 2 2 of the respective modules 2 2 of the respective modules 2 2 have a deeper rolling depth to a deeper rolling depth, respectively, by the depth of the rolling Gradually increase to the shape of the section of the predetermined pipe a (see Figure 6). In addition, the number of the modules 2 2 of the shaped tube forming unit 2 of the present invention and the mold 2 2 1 and the lower mold 2 2 2 of the respective modules 2 2 for the tube body a to pass through the shape structure of the system 13' According to the shape of the required cross-section of the pipe body a, the design j can be designed to be rolled into the cross-sectional shape of each pipe body a as shown in the seventh figure, and the forming method of the present invention is as follows. The flow shown in the eighth figure mainly uses the spiral tube processing a and the shape processing B program respectively to form the tube body 3 of a predetermined sectional shape; wherein: the spiral concave processing A : Implemented in the spiral roller unit ( (see the first system, the hollow pipe body a enters from the inlet end 12 and is taken from the outlet end jade, and is rolled by the roller device 14 from the outer wall of the pipe body 3 To achieve the desired spiral indentation a 1.
