Description of the Invention: [Technical Field] The present invention relates to a method for processing a tubular member, and more particularly to a method for processing a tubular member using a mold clamping machine. [Prior Art] Referring to Fig. 1, a conventional mold clamping machine i includes a mold set η capable of holding a blank 2, and a die set which is disposed relative to the mold set u and which can punch the blank 2 12; the towel set, the mold set u has two separable molds 111', and opposite sides of the molds lu are provided with a placement groove 112 for the placement of the embryo material 2, and a skirt 12 is placed relative to the die The molding groove 113 is disposed at a position and communicates with the placement groove 112. Further, the die device 12 has a punch 121 for impacting the blank 2. Referring to FIG. 1 and FIG. 2, when the mold forming machine i performs a press forming operation on the blank 2, the blank 2 is placed in the placement groove ι 2 and clamped by the molds (1). The billet 2 is impacted by the punch 121 so that the billet 2 - side is stamped and formed. Finally, the mold (1) is separated to separate the billet 2 from the mold group 2 into a secret material 2; However, the raw material 2 is a solid bar, so the blank 2 is subjected to the stamping process of the punch 121, and the blank 2 can be formed according to the shape of the forming groove (1), however, there is no It is thought that the clamping head machine i should be applied to the processing of the tubular member. After all, the difficulty in using it, that is, the processing of the tubular member 2A by using the clamping heading machine i, is also due to the tubular member. The perforation characteristic of 21 is easy to cause the perforation 21 to be easily affected by the impact of the punch 121 during the dusting process, resulting in the occurrence of skew or depression of the perforation 41 (as shown in FIG. 3), resulting in the tubular member 2A. It becomes a defective product. Therefore, in the current technology, it is still not possible to use the mold heading machine to perform the Shaped processing member, the real intake - further improvement. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for processing a tubular member using a mold-closing heading machine which can prevent a tubular member having a perforation from being deformed during a punching process to achieve rapid, The manufacture of the tubular stamping process is successfully completed. Thus, the present invention utilizes a mold clamping machine for processing a tubular member, which includes an initial step, a stamping step, a stripping step, and the like; wherein, in the initial step, a blank having a perforation (ie, a tubular member) is provided. And a die-cutting machine, and the die-forming device of the die-cutting machine has a punch for impacting the blank, and a punch protruding outwardly and extending over the punch The inner stop block and the like are designed such that the stamping section of the blank is subjected to the punching. When the punch is punched, the stopper can be extended into the perforation and supported to block, so that the blank is stamped. Forming a stamping section (ie, a stamping step), and the perforation is not deformed by the formation of the stamping section; that is, the tubular stamping process is performed by the mold clamping machine to effectively achieve rapid and free deformation And other effects. 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. 5 1361114 Referring to FIG. 4 and FIG. 5, a preferred embodiment of the method 3 for processing a tubular member by using a mold clamping machine includes an initial step 31, a stamping step 32, a stripping step 33, and the like. Wherein, the initial step 31 is first provided with a blank 4 and a clamping heading machine (not shown), and the blank 4 (ie, a tubular member) is surrounded by an axis α. a perforation 41, and a blank side is formed on one side of the blank 4, and the other side forms a stop section 43 having an outer diameter larger than the stamping side 42. In addition, the mold heading machine includes a material that can be derailed. a die set 51, and a die device 52 disposed relative to the die set μ and capable of stamping the blank 4, wherein the die set has two separable molds 511, and the die set 52 has a stamping The punch 42 of the side 42 strikes, and a stop block 522 that protrudes outwardly from the punch 521 and just protrudes into the through hole 41. Referring to FIG. 6, in the operation of the embodiment, the stamping step 32 is performed by placing the blanks 4 one by one and being clamped by the two molds 511, and then punching the stamping side 42 of the blank 4 by the die device 52 while making The stopper 522 can extend into the through hole 41, so that the punch 521 can be stamped to form a stamping portion 44' larger than the outer diameter of the blank 4, and the through hole 41 is received by the punching member 521 during the stamping process. The stop block 522 stops the top sill, so that the through hole 41 obtains a better supporting effect, and does not deform due to the forming of the stamping section 42; finally, the step is processed by referring to FIG. 7', the returning step 33 _ After the completion of the blank 4, the mold 511 is separated and then the blank 4 is withdrawn, that is, the processing of the blank 4 is completed; that is, a stopper 522' is protruded outwardly by the punch 52. The perforation 41 obtains the support of the stopper 522 during the pressing process, so that the perforation 41 does not deform, 6
