Description

成形裝置Forming device

本發明是有關於一種成形裝置，特別是指一種低翹曲的成形裝置。The invention relates to a forming device, in particular to a forming device with low warpage.

隨著環保意識的抬頭，各國也陸續提出相關的綠能政策，因此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。然而，大面積的金屬板材容易在沖壓過程中，因應力回彈而產生翹曲現象，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 rising awareness of environmental protection, various countries have successively proposed relevant green energy policies, so the demand for fuel cells has also increased significantly, among which large-area metal bipolar plates are one of the core components of fuel cells. However, large-area metal plates are prone to warping due to stress rebound during the stamping process, resulting in flatness that cannot meet the required standard. Therefore, it is necessary to design a mold that can solve the problem of material warping.

參閱圖1，中華人民共和國第CN 102451869A號專利中揭露了一種成形裝置1，該成形裝置1在固定座11上設置多個電磁產生裝置12，這些電磁產生裝置12可受控制對位於其上的金屬板料13產生強弱不同的電磁斥力，以使金屬板料13貼合位於上方的模具14，並依模具14的表面特徵15成形。該等電磁產生裝置12所產生的高速成形力可提升金屬板料13的成形性，並可減少殘留應力所造成的材料翹曲之問題。然而，該成形裝置1的結構複雜，並需額外使用供電設備來驅動該等電磁產生裝置12，整體所費成本較高。Referring to Figure 1, the People’s Republic of China Patent No. CN 102451869A discloses a forming device 1. The forming device 1 is provided with a plurality of electromagnetic generating devices 12 on a fixed seat 11, and these electromagnetic generating devices 12 can be controlled to The metal sheet 13 generates electromagnetic repulsive forces of different strengths, so that the metal sheet 13 is attached to the mold 14 located above and is shaped according to the surface features 15 of the mold 14. The high-speed forming force generated by the electromagnetic generating devices 12 can improve the formability of the metal sheet 13 and can reduce the problem of material warping caused by residual stress. However, the structure of the forming device 1 is complicated, and an additional power supply device is required to drive the electromagnetic generating devices 12, and the overall cost is relatively high.

因此，本發明之目的，即在提供一種結構簡單且能防止大型板件材料翹曲的成形裝置。Therefore, the object of the present invention is to provide a forming device that has a simple structure and can prevent warping of large-sized plate materials.

於是，本發明成形裝置，包含一下模單元、一上模單元，及一行程控制單元。該下模單元包括一底座、一設置於該底座的下模板，及一設置於該下模板上的下模仁。該上模單元包括一位於該下模仁上方的頂座、一位於該頂座及該下模仁之間的上模仁，及複數連接該頂座及該上模仁的導桿。Therefore, the forming device of the present invention includes a lower mold unit, an upper mold unit, and a stroke control unit. The lower mold unit includes a base, a lower mold plate arranged on the base, and a lower mold core arranged on the lower mold plate. The upper mold unit includes a top seat located above the lower mold core, an upper mold core located between the top seat and the lower mold core, and a plurality of guide rods connecting the top seat and the upper mold core.

該行程控制單元包括一提供該上模仁向上之彈性位能的致動件、一限制該上模仁向上移動的限位機構，及一設置於該下模單元且位於該限位機構下方的切換機構，該切換機構可控制該限位機構不再限位該上模仁，使該上模仁被該致動件帶動而向上移動。The stroke control unit includes an actuator that provides upward elastic potential of the upper mold core, a limit mechanism that limits the upward movement of the upper mold core, and a stopper mechanism arranged on the lower mold unit and located below the limit mechanism The switching mechanism can control the limiting mechanism to no longer limit the upper mold core, so that the upper mold core is driven by the actuator to move upward.

本發明之功效在於：該上模仁沿該等導桿向下移動，以與該下模仁合模使板料第一次成形，接著透過該切換機構使該限位機構不再限制該上模仁，使該上模仁被該致動件向上帶動而產生短暫的開模動作，達到釋放成形壓力之功效，在該上模仁到達上死點而停止上升，之後該導桿繼續帶動該上模仁向下與該下模仁合模，完成第二次的整形動作，本發明透過簡單的結構可在一個成形道次中，完成預成形、釋壓，及二次整形等複合動作，可改善產品的回彈及翹曲現象，從而提升尺寸精度及生產效率。The effect of the present invention is that the upper mold core moves downward along the guide rods to close the mold with the lower mold core to form the sheet for the first time, and then the limit mechanism no longer restricts the upper mold through the switching mechanism. The mold core causes the upper mold core to be driven upward by the actuator to produce a short mold opening action to achieve the effect of releasing the forming pressure. When the upper mold core reaches the top dead center, it stops rising, and then the guide rod continues to drive the The upper mold core is downwardly clamped with the lower mold core to complete the second shaping action. The present invention can complete the composite actions of pre-forming, pressure release, and secondary shaping in one forming pass through a simple structure. It can improve the springback and warpage of the product, thereby improving the dimensional accuracy and production efficiency.

參閱圖2、圖3，及圖5，以下說明本實施例對一板料6成形的過程。首先，將該板料6置於該下模仁23上，該上模單元3位於該下模單元2正上方，此時該復位彈簧422拉動該等側滑塊421向內分別緊抵該等擋塊45，使該等側滑塊421部分位於該上模仁32的正上方，並卡置於該上模仁32及該上模板34之間，使該上模仁32與該上模板34沿上下方向A保持一固定距離。接著，透過液壓裝置等動力來源，驅動該上模板34沿該等導桿33相對於該頂座31向下移動，該上模板34推動該等側滑塊421及該上模仁32向下移動，並使該上模仁32及該下模仁23合模以共同擠壓該板料6，完成第一次的成形動作。此時該等側滑塊421之第一斜面426甫分別貼觸該等導引件431之第二斜面433。Referring to FIGS. 2, 3, and 5, the process of forming a sheet 6 in this embodiment will be described below. First, place the sheet 6 on the lower mold core 23, and the upper mold unit 3 is located directly above the lower mold unit 2. At this time, the return spring 422 pulls the side sliders 421 inward to abut against the respective The stopper 45 makes the side sliding blocks 421 partly located directly above the upper mold core 32 and is clamped between the upper mold core 32 and the upper mold plate 34 so that the upper mold core 32 and the upper mold plate 34 Keep a fixed distance along the up and down direction A. Then, through a power source such as a hydraulic device, the upper mold plate 34 is driven to move downward relative to the top seat 31 along the guide rods 33, and the upper mold plate 34 pushes the side sliders 421 and the upper mold core 32 to move downward , And close the upper mold core 32 and the lower mold core 23 to co-extrude the sheet 6 to complete the first forming action. At this time, the first inclined surfaces 426 of the side sliders 421 just touch the second inclined surfaces 433 of the guide members 431 respectively.

參閱圖2、圖3，及圖6，隨著該上模板34繼續向下移動，壓抵該等第二斜面433的該等第一斜面426，會沿該等第二斜面433滑移，使得該等側滑塊421相對於該等導引件431向下及向外移動而遠離彼此，當該等側滑塊421向外移動而不再壓抵該上模仁32時，該上模仁32不再受到該等側滑塊421的限位，因此該等拉力彈簧411會釋放彈性位能，以帶動該上模仁32相對於該上模板34向上移動，直至該等定位柱44頂抵該上模板34而到達上死點，此時該上模仁32及該上模板34間的距離減少，且該上模仁32脫離該板料6，完成短暫向上開模的動作，此動作可暫時釋放成形壓力，以改善翹曲及回彈之程度。在該上模仁32上移到達上死點後，該上模板34繼續向下移動，使該上模仁32可再次與該板料接觸，該上模仁32會被帶動而持續向下移動，直至下死點，此時該上模仁32與該下模仁23再次合模，並完成第二次的整形動作。需要特別說明的是，雖然一般下死點可以是在該等第一平面425分別壓抵該等第二平面432時到達，但也可以是帶動上模板34的驅動裝置本身先到達下死點(如圖6所示，圖中該等第一平面425未完全壓抵該等第二平面432)。Referring to Figures 2, 3, and 6, as the upper template 34 continues to move downward, the first inclined surfaces 426 pressed against the second inclined surfaces 433 will slide along the second inclined surfaces 433, so that The side sliders 421 move downward and outward relative to the guides 431 to move away from each other. When the side sliders 421 move outward without pressing against the upper mold core 32, the upper mold core 32 is no longer restricted by the side sliders 421, so the tension springs 411 will release the elastic potential energy to drive the upper mold core 32 to move upward relative to the upper template 34 until the positioning posts 44 abut against The upper mold plate 34 reaches the upper dead center. At this time, the distance between the upper mold core 32 and the upper mold plate 34 is reduced, and the upper mold core 32 is separated from the sheet 6 to complete a short upward mold opening action. Temporarily release the forming pressure to improve the degree of warpage and springback. After the upper mold core 32 moves up to the top dead center, the upper template 34 continues to move downward so that the upper mold core 32 can contact the sheet again, and the upper mold core 32 will be driven to continue to move downward , Until the bottom dead center, at this time, the upper mold core 32 and the lower mold core 23 are closed again, and the second shaping action is completed. It should be particularly noted that although the bottom dead center can generally be reached when the first planes 425 are pressed against the second planes 432 respectively, it can also be that the driving device itself that drives the upper template 34 first reaches the bottom dead center ( As shown in FIG. 6, the first planes 425 are not completely pressed against the second planes 432).

參閱圖2、圖3，及圖7，完成成形後，該等側滑塊421被驅動而向上移動，從而帶動該上模板34及該上模仁32向上朝該頂座31移動，使得該上模仁32與該下模仁23分離而完成開模動作。該上模板34繼續上移，在此過程中，該等導桿33向下推抵該上模仁32，使該上模仁32向下遠離該上模板34，由於該復位彈簧422持續向內拉動該等側滑塊421(但受到該上模仁32的阻擋)，因此當該上模板34及該上模仁32沿上下方向A間的距離大於該等側滑塊421的高度時，該等側滑塊421不再受到該上模仁32的阻擋而向內移動，直至分別靠抵該等擋塊45，並重新卡置於該上模板34及該上模仁32之間，完成復位而可進行下一次的板料成形。Referring to Figures 2, 3, and 7, after forming is completed, the side sliders 421 are driven to move upward, thereby driving the upper template 34 and the upper mold core 32 to move upward toward the top seat 31, so that the upper The mold core 32 is separated from the lower mold core 23 to complete the mold opening operation. The upper mold plate 34 continues to move upward. In this process, the guide rods 33 push the upper mold core 32 downward, so that the upper mold core 32 moves downward and away from the upper mold plate 34, because the return spring 422 continues to move inward Pull the side sliders 421 (but are blocked by the upper mold core 32), so when the distance between the upper template 34 and the upper mold core 32 in the vertical direction A is greater than the height of the side sliders 421, the The side sliding block 421 is no longer blocked by the upper mold core 32 and moves inward until it abuts against the stop blocks 45 respectively, and is clamped between the upper template 34 and the upper mold core 32 again to complete the reset And the next sheet metal forming can be done.

本實施例的結構簡單而無需另外建置額外的電源或設備，剛性且不複雜的模具結構可提高使用壽命及強度。且本實施例可在一個成形道次中，完成預成形、釋壓，及二次整形等複合動作，以使大型金屬板件成形且減少其回彈及翹曲之情形。The structure of this embodiment is simple and does not require additional power supply or equipment. The rigid and uncomplicated mold structure can improve the service life and strength. In addition, this embodiment can perform compound actions such as pre-forming, pressure release, and secondary shaping in one forming pass, so as to form large metal plates and reduce their springback and warpage.

綜上所述，本發明透過簡單的結構可在一個成形道次中，完成預成形、釋壓，及二次整形等複合動作，可改善產品的回彈及翹曲現象，從而提升尺寸精度及生產效率，故確實能達成本發明之目的。To sum up, the present invention can complete composite actions such as pre-forming, pressure release, and secondary shaping in one forming pass through a simple structure, which can improve product springback and warpage, thereby improving dimensional accuracy and Production efficiency can indeed achieve the purpose of the invention.
