長套筒的成型方法Long sleeve forming method

本發明是有關於一種成型方法，特別是指一種長套筒的成型方法。The present invention relates to a molding method, and more particularly to a method of forming a long sleeve.

參閱圖1，現有中空套筒的成型方法依序包括下列步驟：首先，步驟11是準備預定長度的原料100，而步驟12是將原料100的兩端整型成為圓角，然後，步驟13是使原料100的頂端向下凹陷成為一初胚101，接下來，步驟14是深沖擠壓該初胚101的兩端而成為一深沖胚料102，該深沖胚料102具有相對的一深凹槽103與一淺凹槽104，及一介於該深凹槽103與該淺凹槽104之間的分隔壁105，接著，步驟15是衝剪該分隔壁105以成型出一半成品106，最後，步驟16，是利用車修加工切削該中空套筒106的內面以製成一中空套筒107。Referring to FIG. 1, the conventional hollow sleeve forming method sequentially comprises the following steps: First, step 11 is to prepare a predetermined length of the raw material 100, and in step 12, the both ends of the raw material 100 are rounded, and then step 13 is The top end of the raw material 100 is recessed downward into an initial embryo 101. Next, the step 14 is deep drawing and pressing the two ends of the original embryo 101 to form a deep-drawn blank 102, and the deep-drawn blank 102 has an opposite one. a deep groove 103 and a shallow groove 104, and a partition wall 105 interposed between the deep groove 103 and the shallow groove 104, and then, in step 15, the partition wall 105 is punched to form a half of the finished product 106, Finally, in step 16, the inner surface of the hollow sleeve 106 is cut by car repair to form a hollow sleeve 107.

現有中空套筒的成型方法雖然可以製成中空套筒107，但是，由於最後仍需進行車修加工，因此，在設計上必須預留供車修加工的材料量，不僅增加原料成本，而且額外增加車修加工也使得現有中空套筒的生產效率較低。Although the existing hollow sleeve forming method can be made into the hollow sleeve 107, since the vehicle repair processing is still required at the end, the amount of material for the vehicle repair processing must be reserved in the design, which not only increases the raw material cost but also adds The addition of the car repair process also makes the production efficiency of the existing hollow sleeve low.

因此，本發明之目的，即在提供一種無須車修加工而能降低成本提高生產效率的長套筒的成型方法。Accordingly, it is an object of the present invention to provide a molding method for a long sleeve which can be reduced in cost and improved in production efficiency without requiring a vehicle to be repaired.

於是，本發明長套筒的成型方法依序包含下列步驟：步驟(A)是準備一預定尺寸的柱狀原料，該原料具有相反的一第一端與一第二端。步驟(B)是在該原料的第一端成型出一第一倒角。步驟(C)是在該原料的第一端成型出一第一凹坑，同時在該原料的第二端成型一第二倒角。步驟(D)是在該原料的第二端成型出一第二凹坑，並沿該第一凹坑擠壓該原料的第一端，而成型出一由該第一端朝向該第二端方向延伸的第一凹槽。步驟(E)是鍛打該原料，使該原料具有一由該第二端朝向該第一端方向延伸的頭部、一個由該第一端朝向該頭部方向延伸的桿部，及一個一體連設該頭部與該桿部的縮頸部，該縮頸部的斷面是由該頭部朝向該桿部方向漸縮。步驟(F)是沿該第二凹坑擠壓該原料的第二端，而成型出一由該第二端朝向該桿部方向延伸的第二凹槽，及一介於該第二凹槽與該第一凹槽之間的分隔壁。Thus, the forming method of the long sleeve of the present invention sequentially comprises the following steps: Step (A) is to prepare a columnar material of a predetermined size, the material having an opposite first end and a second end. Step (B) is to form a first chamfer at the first end of the material. In the step (C), a first pit is formed at the first end of the material, and a second chamfer is formed at the second end of the material. Step (D) is: forming a second pit at the second end of the material, and pressing the first end of the material along the first pit to form a first end toward the second end a first groove extending in the direction. Step (E) is forging the material so that the material has a head extending from the second end toward the first end, a stem extending from the first end toward the head, and an integral body The head portion and the constricted portion of the rod portion are connected, and the cross section of the constricted portion is tapered from the head portion toward the rod portion. Step (F) is: pressing a second end of the material along the second recess to form a second groove extending from the second end toward the rod portion, and a second groove a partition wall between the first grooves.

本發明之功效在於：依序經由上述步驟能使該原料所成型出的長套筒，無需經過切削製程，能有效降低設備與原料成本，減少加工時間提高生產效率，還能提升整體強度。The effect of the invention is that the long sleeve which can be formed by the raw material through the above steps can effectively reduce the cost of equipment and raw materials, reduce the processing time, improve the production efficiency, and improve the overall strength without going through the cutting process.

參閱圖2，本發明長套筒的成型方法的實施例依序包含下列步驟：首先，步驟21是準備一預定尺寸的柱狀原料3，該原料3具有相反的一第一端31與一第二端32。於本實施例中，該原料3是圓柱狀。Referring to Figure 2, an embodiment of the method for forming a long sleeve of the present invention comprises the following steps: First, step 21 is to prepare a columnar material 3 of a predetermined size, the material 3 having an opposite first end 31 and a first Two ends 32. In the present embodiment, the raw material 3 is cylindrical.

接著，步驟22是在該原料3的第一端31成型出一第一倒角311。接下來，步驟23是將經過步驟22的該原料3的第一端31與第二端32上下倒置後，再於該原料3的第一端31成型出一第一凹坑312，同時在該原料3的第二端32成型一第二倒角321。Next, in step 22, a first chamfer 311 is formed at the first end 31 of the material 3. Next, in step 23, after the first end 31 and the second end 32 of the raw material 3 passing through the step 22 are inverted upside down, a first recess 312 is formed on the first end 31 of the raw material 3, and at the same time The second end 32 of the material 3 is formed with a second chamfer 321 .

參閱圖2、3、4，步驟24是在該原料3的第二端32成型出一第二凹坑322，並沿該第一凹坑312擠壓該原料3的第一端31，而成型出一由該第一端31朝向該第二端32方向延伸的第一凹槽313。該第一凹槽313具有一由該第一端31朝向該第二端32方向延伸且斷面為多邊形的第一段314，及一由該第一段314朝向該第二端32方向延伸且斷面為圓形的第二段315。於本實施例中，該第一段314的斷面為六邊形。Referring to Figures 2, 3 and 4, step 24 is to form a second recess 322 at the second end 32 of the material 3, and press the first end 31 of the material 3 along the first recess 312 to form A first recess 313 extending from the first end 31 toward the second end 32 is formed. The first groove 313 has a first segment 314 extending from the first end 31 toward the second end 32 and having a polygonal cross section, and a first segment 314 extending toward the second end 32 and The second section 315 is circular in cross section. In this embodiment, the first section 314 has a hexagonal cross section.

在此要特別說明的是，由於步驟24是沿該第一凹坑312反向擠壓該原料3的第一端31，因此，步驟24中原料3的長度會大於前一步驟23的原料3長度。It should be particularly noted that since the step 24 is to reversely press the first end 31 of the raw material 3 along the first recess 312, the length of the raw material 3 in step 24 is greater than the raw material 3 of the previous step 23. length.

然後，步驟25是先將經過該步驟24的該原料3的第一端31與第二端32倒置後再鍛打該原料3，使該原料3具有一由該第二端32朝向該第一端31方向延伸的頭部33、一個由該第一端31朝向該頭部33方向延伸的桿部34，及一個一體連設該頭部33與該桿部34的縮頸部35，該縮頸部35的斷面是由該頭部33朝向該桿部34方向漸縮，而且該桿部34的外徑小於該頭部33的外徑。Then, in step 25, the first end 31 and the second end 32 of the raw material 3 passing through the step 24 are inverted, and then the raw material 3 is forged, so that the raw material 3 has a second end 32 facing the first a head portion 33 extending in the direction of the end 31, a rod portion 34 extending from the first end 31 toward the head portion 33, and a constricted portion 35 integrally connecting the head portion 33 and the rod portion 34. The cross section of the neck portion 35 is tapered by the head portion 33 toward the rod portion 34, and the outer diameter of the rod portion 34 is smaller than the outer diameter of the head portion 33.

參閱圖2、5，步驟26是沿該第二凹坑322擠壓該原料3的第二端32，而成型出一由該第二端32朝向該桿部34方向延伸且斷面為多邊形的第二凹槽323，及一介於該第二凹槽323與該第一凹槽313之間的分隔壁36。於本實施例中，該第二凹槽323的斷面為四邊形。Referring to FIGS. 2 and 5, step 26 is to press the second end 32 of the material 3 along the second recess 322 to form a polygonal shape extending from the second end 32 toward the rod portion 34. The second groove 323 and a partition wall 36 between the second groove 323 and the first groove 313. In the embodiment, the second groove 323 has a quadrangular cross section.

在此要特別說明的是，由於步驟26是沿該第二凹坑322反向擠壓該原料3的第二端32，因此，步驟26中原料3的長度會大於步驟25中原料3的長度。Specifically, since the step 26 is to reversely press the second end 32 of the raw material 3 along the second recess 322, the length of the raw material 3 in the step 26 is greater than the length of the raw material 3 in the step 25. .

最後，步驟27是沖斷該分隔壁36以連通該第一凹槽313與該第二凹槽323，而製成一長套筒4。Finally, step 27 is to break the partition wall 36 to connect the first recess 313 and the second recess 323 to form a long sleeve 4.

在此要特別說明的是，上述步驟21至步驟27都是利用相對應的模具進行，而模具的設計為本領域技術人員的現有知識，在此不予多加贅述。It should be particularly noted that the above steps 21 to 27 are all performed by using corresponding molds, and the design of the mold is known to those skilled in the art, and will not be further described herein.

綜上所述，本發明長套筒的成型方法的實施例依序經由上述步驟能使該原料3所成型出的長套筒4，無需經過切削製程，能有效降低設備與原料成本，減少加工時間提高生產效率，還能提升整體強度，故確實能達成本發明之目的。In summary, the embodiment of the forming method of the long sleeve of the present invention can sequentially form the long sleeve 4 formed by the raw material 3 through the above steps, without the need of a cutting process, which can effectively reduce the cost of equipment and raw materials, and reduce processing. Time increases the production efficiency and also improves the overall strength, so it is indeed possible to achieve the object of the present invention.
