隨著環保意識的抬頭，各國也陸續提出相關的綠能政策，其中燃料電池的需求量也因而大幅增加，其中大面積的金屬雙極板是燃料電池的核心元件之一，其材質容易在模製過程中產生翹曲和回彈現象，造成平坦度無法達到所需標準，故需設計可解決材料翹曲之問題的模具。With the rise of environmental awareness, countries have also put forward related green energy policies. The demand for fuel cells has also increased significantly. Among them, large-area metal bipolar plates are one of the core components of fuel cells. During the manufacturing process, warping and springback phenomena occur, causing the flatness to fail to meet the required standard, so it is necessary to design a mold that can solve the problem of material warping.

參閱圖1，在中國人民共和國第CN101504984A號專利中，其將上模11或下模12其中之一的模具材料改以橡膠13代替，透過受壓後可產生形變的橡膠13帶著胚料14一同填充型腔，並能克服胚料14的翹曲及回彈問題。然而，橡膠材料容易耗損而導致使用壽命較短，且耗損後會因精度下降而影響產品的良率，使整體的加工品質不甚穩定。Referring to FIG. 1, in the Patent No. CN101504984A of the People ’s Republic of China, the mold material of one of the upper mold 11 or the lower mold 12 is replaced with rubber 13, and the deformed rubber 13 carries the blank 14 through compression Fill the cavity together and overcome the warpage and rebound problems of the blank 14. However, the rubber material is easy to wear, resulting in a short service life, and after the wear, the accuracy of the product will be reduced and the yield of the product will be affected, making the overall processing quality unstable.

因此，本發明之目的，即在提供一種耐用且能降低板材翹曲及回彈現象的複合沖壓成形裝置。Therefore, the object of the present invention is to provide a composite stamping and forming device which is durable and can reduce the warpage and springback of the sheet.

Each push rod 44 has a rod body 441 extending downward from the upper die pad 34, and a roller 442 pivotally disposed at the bottom end of the rod body 441.

參閱圖2及圖5，以下說明本實施例的成形過程，首先先將一板料A如圖5所示地置於該下模仁31及該上模仁32之間，並透過驅動裝置使該上模墊34向下朝該下模墊21移動。參閱圖6、圖7，及圖8，該上模仁32受到該上模墊34的推動而向下移動，且該上模仁32透過該板料A向下推動該下模仁31，該下模仁31在向下移動的過程中會如圖6所示地壓縮該等第二彈性件24，從而受到該等第二彈性件24向上的彈性力作用，使該下模仁31及該上模仁32如圖7所示地對該板料A進行預成形。該下模仁31持續向下直至如圖8所示地壓抵該模板22之該等凸塊部222，使該模板22向下並開始壓縮該等第一彈性件23，此時該下模仁31受到的向上作用力微幅增加，使該下模仁31及該上模仁32對該板料A進一步整型，此時該等推桿44之滾輪442分別與該等滑塊42之平面422滾動接觸。2 and 5, the following describes the forming process of this embodiment, first of all, a sheet material A is placed between the lower mold core 31 and the upper mold core 32 as shown in FIG. The upper die pad 34 moves downward toward the lower die pad 21. 6, 7, and 8, the upper mold core 32 is pushed downward by the upper mold pad 34, and the upper mold core 32 pushes the lower mold core 31 downward through the sheet A, the During the downward movement of the lower mold core 31, the second elastic members 24 will be compressed as shown in FIG. 6, so as to be subjected to the upward elastic force of the second elastic members 24, so that the lower mold core 31 and the The upper die core 32 preforms the sheet A as shown in FIG. 7. The lower mold core 31 continues downward until it presses against the protrusions 222 of the template 22 as shown in FIG. 8, so that the template 22 is downward and begins to compress the first elastic members 23, at this time the lower mold The upward force received by the kernel 31 slightly increases, and the lower mold kernel 31 and the upper mold kernel 32 further shape the sheet A. At this time, the roller 442 of the push rod 44 and the slider 42 respectively The plane 422 is in rolling contact.

參閱圖9及圖10，該模板22續行向下移動直至該等滑塊42之斜面421分別與該等擋體41之滑移面411滑動接觸，此時該等擋體41透過該等滑塊42給予該模板22向上的作用力，以給予該下模仁31向上的合模力道，進而對該板料A進行下一階段的整形，且該模板22仍可向下繼續移動。參閱圖3、圖11，及圖12，隨著該模板22繼續向下移動，該等滑塊42之斜面421會沿該等擋體41之滑移面411向外滑移，同時也沿該等滑槽223水平向外移動，並分別拉伸該等復位件43而使其儲存彈性位能。此時該等平面422因為與該等滾輪442滾動接觸，滾輪442施加於平面422的摩擦力極小，該摩擦力不會限制滑塊42向外移動，當該模板22如圖11所示地壓抵該下模墊21之該等擋塊部212時，該下模仁31會受到更大的向上作用力，而如圖12所示地與該上模仁32進一步合模，以對該板料A進行下一階段的整形。參閱圖13及圖14，在該模板22壓抵該等擋塊部212時，該等滾輪442仍可向下移動至一下死點，此時該等滾輪442完全進入該等設置空間220中，該等桿體441則壓抵該模板22而被限位，到達下死點後，該下模仁31與該上模仁32如圖14所示地完全合模，以完成對該板料A的成形。接著驅動裝置卸除對該上模墊34的驅動力道，在前述過程中被壓縮的該等第一彈性件23及該等第二彈性件24，以及因該等滑塊42向外滑移而被拉伸的該等復位件43，會帶動各元件向上和向內復位回上死點(即圖2的位置)，從而將該板料A成形為一板材。Referring to FIGS. 9 and 10, the template 22 continues to move downward until the inclined surfaces 421 of the sliders 42 are in sliding contact with the sliding surfaces 411 of the blocking bodies 41, at which time the blocking bodies 41 pass through the sliding surfaces The block 42 gives the template 22 upward force to give the lower mold core 31 an upward clamping force, and then the sheet A is shaped in the next stage, and the template 22 can still continue to move downward. Referring to FIGS. 3, 11, and 12, as the template 22 continues to move downward, the inclined surfaces 421 of the sliders 42 will slide outward along the sliding surfaces 411 of the blocking bodies 41, and also along the The equal sliding groove 223 moves horizontally outward, and respectively stretches the resetting members 43 to store elastic potential energy. At this time, since the flat surfaces 422 are in rolling contact with the rollers 442, the friction force exerted by the rollers 442 on the flat surfaces 422 is extremely small. The friction force does not restrict the slider 42 from moving outward. When the template 22 is pressed as shown in FIG. When contacting the stopper portions 212 of the lower mold pad 21, the lower mold core 31 will receive a greater upward force, and as shown in FIG. 12 and the upper mold core 32 are further closed to mold the plate Material A undergoes the next stage of shaping. Referring to FIGS. 13 and 14, when the template 22 is pressed against the stopper portions 212, the rollers 442 can still move down to the bottom dead center. At this time, the rollers 442 completely enter the installation spaces 220. The rods 441 are pressed against the template 22 and are limited. After reaching the bottom dead center, the lower mold core 31 and the upper mold core 32 are completely closed as shown in FIG. 14 to complete the sheet A Of shaping. Then the driving device removes the driving force to the upper die pad 34, the first elastic members 23 and the second elastic members 24 that were compressed in the foregoing process, and the sliders 42 slide outward The stretched return members 43 will drive each element to return to the top dead center (ie, the position in FIG. 2) upward and inward, thereby forming the sheet A into a plate.

本實施例可在一道次中完成前述的預成形及多階段整形，達到複合沖壓之作用，以避免該板料A單次成形的形變量過大，從而可減少回彈現象的產生，並可簡化製程，加上本實施例的結構簡單且不需使用橡膠等容易耗損之元件，可減少整體的製造成本及時間，並增加使用壽命及穩定成形品質。此外，在該下模仁31及該上模仁32由上死點移動至下死點，再復位回上死點的過程中，該下模仁31及該上模仁32皆可維持持壓狀態，使成形出的板材完全貼模，減少翹曲及回彈現象，提升成形後板材之精度。In this embodiment, the aforementioned pre-forming and multi-stage shaping can be completed in one pass to achieve the function of compound stamping to avoid excessive deformation of the sheet A in a single forming, thereby reducing the occurrence of springback and simplifying The manufacturing process, coupled with the simple structure of this embodiment and no need to use rubber and other easily worn components, can reduce the overall manufacturing cost and time, and increase the service life and stabilize the forming quality. In addition, during the process of moving the lower mold core 31 and the upper mold core 32 from the top dead center to the bottom dead center, and then resetting to the top dead center, both the lower mold core 31 and the upper mold core 32 can maintain holding pressure In this state, the formed sheet is completely attached to the mold, reducing warpage and springback, and improving the accuracy of the formed sheet.

需要特別說明的是，該等推桿44不一定要透過該等滾輪442與該等滑塊42滾動接觸，也可以在滑塊42上增設朝向上方的傾斜面，並以楔形塊與該滑塊42滑動接觸以取代該等滾輪442，但不以此為限。It should be noted that the push rods 44 do not have to be in rolling contact with the sliders 42 through the rollers 442, and an inclined surface facing upwards may be added to the slider 42 and a wedge-shaped block and the slider 42 Sliding contact to replace the rollers 442, but not limited to this.

綜上所述，本發明透過前述結構而可達成預成形及多段整形之複合作動，可避免單次成形的形變量過大，且成形過程中皆可維持持壓狀態，有效降低翹曲及回彈現象，故確實能達成本發明之目的。In summary, the present invention can achieve pre-forming and multi-segment reshaping through the aforementioned structure, which can avoid excessive deformation of a single forming, and can maintain the holding state during the forming process, effectively reducing warpage and springback Phenomenon, it can indeed achieve the purpose of cost invention.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above are only examples of the present invention, and should not be used to limit the scope of implementation of the present invention, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the contents of the patent specification are still Within the scope of the invention patent.
