第5頁 4 6 03 7 6 五、發明說明（3) ，其步驟如下： a. 首先，將管材3 0置入一加工裝置1之槽體1 0内， 並浸入於適當溫度之熱水、熱溶液或以熱空氣加熱， 該溫度則視管材3 0之材質而定，以期使管材3 0能 產生軟化者。 b. 將管材3 0通過加工模具2 0之加工，使管材3 0 — 端由外模體2 2及内模體2 4間之環形通道2 6通過 ，其主要係由該内模體2 4呈圓錐狀之一端進入，藉 以將管材3 0 口徑經由通過該内模體2 4後產生擴大 之情形，使橫向方向處產生伸長之效果，而管材3 0 則經由該加工模具2 0之環形通道2 6後，由該槽體 1 0之開孔1 2處施力拉出，同時在管材3 0軸向方 向處亦產生拉伸之效果。 c. 最後，在拉伸而出之管材3 0内澆淋以冷水，使管材 3 0之管壁由内壁面向外壁面處急速冷卻，並在管壁 上同時產生殘留應力之效果。 故，本發明之原理，主要係藉由塑膠管材在加熱狀態 下在受到任意方向之形變力時，該物體所組成之分子鏈將 會順從於形變方向而產生規則之排列，換言之，當本發明 之管材3 0在經由内模具2 4及外模具2 2將管徑進行擴 大時，將會同時沿著管徑所擴大之方向產生規則之排列， 使分子鏈a概呈環狀排列於管材3 0管體上；同時，當管 材3 0管體受外力而拉伸時，亦將會同時使得分子鏈b沿 者所拉伸之方向即逕向方向產生規則之排列，如第5圖所Page 5 4 6 03 7 6 V. Description of the invention (3), the steps are as follows: a. First, the pipe 30 is placed in the tank 10 of a processing device 1 and immersed in hot water at an appropriate temperature, Hot solution or hot air heating, the temperature depends on the material of the pipe 30, in order to make the pipe 30 can be softened. b. Pass the pipe 30 through the processing die 20 to pass the pipe 30 through the annular passage 26 between the outer die 22 and the inner die 24, which is mainly passed through the inner die 2 4 It enters at one end in a conical shape, so that the diameter of the pipe 30 is enlarged after passing through the inner mold body 24, so that the effect of elongation is generated in the lateral direction, and the pipe 30 is passed through the annular passage of the processing mold 20 After 26, force is pulled out from the opening 12 of the groove 10, and at the same time, the effect of stretching in the axial direction of the pipe 30 is also produced. c. Finally, cold water is poured into the pipe 30 which is stretched, so that the pipe wall of the pipe 30 is rapidly cooled from the inner wall to the outer wall surface, and the effect of residual stress on the pipe wall is generated at the same time. Therefore, the principle of the present invention is mainly that when a plastic pipe is subjected to a deformation force in an arbitrary direction under a heated state, the molecular chain formed by the object will obey the deformation direction to produce a regular arrangement. In other words, when the present invention When the pipe diameter 30 is enlarged through the inner mold 24 and the outer mold 22, a regular arrangement will be generated along the direction in which the pipe diameter is enlarged, so that the molecular chains a are arranged in a ring shape on the pipe 3 0 on the pipe body; at the same time, when the pipe 30 is stretched by external force, it will also cause the molecular chain b to have a regular arrangement along the direction in which it is stretched, that is, as shown in Figure 5.

Description of the invention (4). In this way, the internal molecular bonds a and b of the pipe material 3 0 ′ processed by the present invention can be intersected and shaped within the pipe material 30 in the transverse and radial directions, respectively. It is known that when the molecules of the substance formed by the object When the arrangement is more regular, the strength of the formed objects will be more strengthened. Therefore, the present invention can make the molecular chain composed of the pipe 30 regular by the physical processing method without changing the material of the pipe 30 Those who are positioned in order to enhance their strength. Also, for pipes that need to withstand the internal pressure of the pipe, the pressure on the pipe is generally gradually reduced from the inner wall of the pipe to the outer wall, so that the internal pressure that the existing pipe can withstand cannot be too high. When the internal pressure is too high, It will make the material cracked and damaged; and in order to increase the bearing force of the pipe 30, the present invention is mainly water in the pipe 30 at the opening 12 of the tank, #, and at the same time stretched and The inner pipe of the pipe 30 was washed with cold and the wall was rapidly cooled from the inside to the outside. ★ The pipe 30 was used to make the meat-filling keys be arranged in a regular manner after the deformation force was regularly arranged. The more the pipe f had residual compressive stress In the inner wall of the pipe 30, generally speaking, _ p, _. 〇 gradually increasing the residual compressive stress in the direction of the inner wall '喑 Rabbit two philosophers in the direction of the outer wall, the greater the residual tension should be shown in the internal pressure; … Will allow the pipe material 30 to withstand the distribution of internal stress on the pipe wall as shown in Figure 7, as shown in the last figure * which shows the internal stress and residual compressive stress that can be generated by internal pressure, as shown in Figure 8 囷. ί The tensile stress actually experienced inside the wall is reduced, such as The residue is visible through the plastic pipe Shang Ϊ allow the processing of the present invention stress' 30 for increasing the resistance to pressure pipe 3 having a solid square
