Description of the invention (1) The present invention provides a "manufacturing method and structure of elbow joints", especially a bent pipe with the same size at both ends, which makes it easier to assemble; There are cutting marking lines with a certain inclination of several props, which makes the present invention have an index function when cutting, which is very convenient. It is the feature of this case. The end can be plugged in. The 90-degree bend has a smaller 90-degree bend. The internal injection is separated, but it has a certain end, which is now completed by softening. Therefore, the taper is formed by overlapping, and it is caused by cold to change the straight pipe bending method of the elbow joint of the present invention, which is a column-shaped folding insert that is folded, that is, after having a certain plastic, it can be made In the other state, it is a submission. Once the upper space is used, the insert block's draft is inserted by the plastic at 90 degrees. Therefore, at one end, another 90 degrees is used for drawing and lower molds. However, the internal hard plastic pipe, butt joints between the two and exhaust pipe fittings, has a bent body with a smaller diameter, but one end is larger and the other is inserted. The upper and lower molds of the block pull out the insert block and taper the upper and lower molds. Therefore, after drying, the tube body block that is bent in a timely manner has a taper. When it is used, it will be too small, and the pipe must be inserted and forced. The two ends of the pipe body are overlapped-they must be baked and fired before being fired, and then they are cooled until they are overlapped. It is customary to manufacture elbows, that is, the diameter at one end is more necessary, and the rate is high. Time-shaped and bad methods of major mesh joints are large The other end of the assembly steps are more roasted take pipe 'system is small, uneven ends sudden increase in work ^ μ =, $ processing result, it is difficult to shoulder major disadvantage of conventional. Fire-cooked steam, other bending control, Bao Wei invented a special

Description of the invention (2) Yes: (1) Mold grooves are engraved on the upper and lower molds, and when they are mated with each other, a shape of a tubular joint can be formed, and several strips with a certain inclination are carved in the same fashion ( (For example, 30, 45, 60 degrees, etc.); (2) the mold groove at the 90-degree angle is provided with a slide groove at each end of the mold groove; (3) two sliders, which The length is exactly one half of the elbow joint, and its diameter is exactly the diameter of the through hole of the elbow joint. Then place the two sliders at the center of the mold groove where the upper and lower molds meet; (4) the end of the two sliders is connected Set the hydraulic cylinder and push the slider into the mold slot with the hydraulic cylinder. After the casting material is filled, the bent tube can be formed in the mold slot. The large draft taper makes the dimensions of the two ends of the elbow joint the same, which is more convenient for processing. Another object of the present invention is to provide a hollow pipe fitting with a 90-degree bend, in which a number of marking lines are provided on the outer edge of the right angle of the bent pipe at the center to facilitate cutting in processing. In order for your review committee to further understand the content of this case, please refer to the simple description with reference to the drawings, and the detailed description is as follows: The present invention is mainly capable of manufacturing elbow joints bent at 90 degrees, and the elbow joints The two ends are of the same size structure, please refer to the schematic diagram of the production process of the present invention shown in the first figure; and please refer to the structure exploded view shown in the second diagram; the manufacturing steps of the present invention are: The upper and lower molds (1 0) (100) are engraved with mold grooves (1 1), so that when the two mold grooves (1 1) are mated, a shape of a tubular joint can be molded, which is similar to the fashion engraving. Several cutting marks (110) with a certain inclination (such as 30 °, 45 °, 60 °, etc.). 2. The die groove (1 1) at the 90-degree angle is provided at each of its two ends.
534844 五、發明說明（3) 一滑槽（1 2 )。 三·請參看第二、三圖所示，設二滑塊（2 0 ) (21) ，其長度恰為彎管接頭（3 0 )之一半，其直徑正是 彎管接頭（3 0 )之貫穿孔（3 2 )的直徑，則將二 滑塊（2 0 ) ( 2 1 )分別置於上、下模具（1 0 ) (100)對合之模槽（11)中央處。 四·請參看第三、四、五圖所示，二滑塊（20) (21 )末端接設油壓缸，並以油壓缸推動滑塊（2 0 ) (2 1 )伸入模槽（1 1 )，則再加注鑄材後，彎管接 頭（3 0 )即可在模槽（1 1 )内成型；由於二滑塊 (20) ( 2 1 )分別自兩端滑槽（1 2 )退出，不 $ 需要太大的拔模錐度，使彎管接頭兩端之尺寸為同一 ，加工更為方便；。 請參看第二圖所示，本發明所製成之彎管接頭（3 0 )於中央之直角外緣兩端係形成有標示線（3 1 )，係用 來當彎管接頭（3 0 )有特定角度之切割時，能擇一適切 之標示線（3 1 )予以切割，使加工更為方便；另外由於 彎管接頭（3 0 )係由兩端以滑塊（2 0 )配合製成，故 其兩端不需要太大的拔模錐度，因此可以得到兩端管口同 尺寸的彎管接頭（3 0 )，在加工上更為方便。 由於本發明人以積極的態度，多加開發與努力，終致 創獲本產品，具有如上述之優良功效，應符合申請發明專 4 利之要件，特提出申請，並請 貴審查委員能早日賜予發 明專利為感。534844 V. Description of the invention (3) A chute (1 2). 3. Please refer to the second and third figures, and set two sliders (20) (21), whose length is exactly half of the elbow joint (30), and its diameter is exactly one of the elbow joint (30). For the diameter of the through hole (3 2), the two sliders (2 0) (2 1) are respectively placed at the center of the mold groove (11) where the upper and lower molds (1 0) (100) are aligned. 4. Please refer to the third, fourth, and fifth figures. A hydraulic cylinder is connected to the end of the two sliders (20) (21), and the hydraulic cylinder pushes the slider (2 0) (2 1) into the die slot. (1 1), after the casting material is refilled, the elbow joint (3 0) can be formed in the die groove (1 1); since the two sliders (20) (2 1) are respectively chute from both ends ( 1 2) To exit, do not need too much draft taper, so that the dimensions of the two ends of the elbow joint are the same, and the processing is more convenient; Please refer to the second figure, the elbow joint (3 0) made by the present invention is formed with marking lines (3 1) at both ends of the right-angle outer edge of the center, which are used as the elbow joint (3 0) When cutting at a specific angle, you can choose a suitable marking line (3 1) to cut it, which makes the processing more convenient. In addition, the elbow joint (30) is made of two ends with sliders (20). Therefore, the two ends do not need too much draft taper, so the elbow joint (30) with the same size of the mouth of the two ends can be obtained, which is more convenient in processing. As the inventor took a positive attitude, and developed and worked hard, he finally created this product, which has the excellent effects as described above, and should meet the requirements of applying for patents for inventions. He submits an application and asks your reviewing committee to grant an invention patent at an early date. Feeling.
