Description
本創作有關於一種金屬板材成型裝置，有利於將成型的金屬板材由模具上卸下。 The present invention relates to a sheet metal forming apparatus which facilitates the removal of a formed metal sheet from a mold.
加壓成型是一種常見的金屬板材加工方法，並具有製作成本低廉、製作效率高及製作品質一致的優點。因此加壓成型所生產的加壓件普遍被應用在各種不同的領域，例如：消費電子產品、機械裝置、五金材料或運輸載具等。 Press forming is a common metal sheet processing method, and has the advantages of low production cost, high production efficiency and consistent production quality. Therefore, the pressurizing members produced by press molding are generally used in various fields such as consumer electronic products, mechanical devices, hardware materials or transportation vehicles.
一般而言，透過加壓成型加工金屬板材的過程中，首先會加熱金屬板材，以利於進行後續金屬板材的成型步驟。當金屬板材被加熱到一定的溫度後，便可將金屬板材放置在兩個模具之間，而後再將加壓的流體輸入其中一個模具與金屬板材之間。 In general, in the process of processing a metal sheet by press molding, the metal sheet is first heated to facilitate the subsequent step of forming the sheet metal. After the sheet metal is heated to a certain temperature, the metal sheet can be placed between the two molds, and then the pressurized fluid is fed between one of the molds and the metal sheet.
輸送至其中一個模具與金屬板材之間的流體，將會施加壓力給金屬板材，使得金屬板材因為加壓流體的作用，而貼附在另一個模具的內部，以完成金屬板材加壓成型的步驟。 The fluid delivered to one of the molds and the metal sheet will apply pressure to the sheet metal, so that the sheet metal is attached to the inside of the other mold due to the action of the pressurized fluid to complete the step of press forming the sheet metal. .
透過上述的步驟雖然可以完成金屬板材的加工，但金屬板材 在經過加壓之後，往往會緊密的貼合在模具的內部，而不利於操作人員將經過加壓的金屬板材由模具上卸下，進而影響了金屬板材成型的製作效能。 Through the above steps, although the processing of sheet metal can be completed, the sheet metal is After being pressurized, it tends to fit tightly inside the mold, which is unfavorable for the operator to remove the pressed metal sheet from the mold, thereby affecting the production efficiency of the sheet metal forming.

請參閱第1圖，為本創作金屬板材成型裝置一實施例的構造示意圖。如圖所示，本創作所述的金屬板材成型裝置10主要包括一第一模具11、一第二模具13、至少一輸送管15及一流體輸送單元17，其中流體輸 送單元17透過輸送管15連接第一模具11，而第一模具11則可與第二模具13接合。 Please refer to FIG. 1 , which is a schematic structural view of an embodiment of a metal sheet forming apparatus. As shown in the figure, the sheet metal forming apparatus 10 of the present invention mainly includes a first mold 11, a second mold 13, at least one conveying pipe 15, and a fluid conveying unit 17, wherein the fluid is transferred. The feeding unit 17 is connected to the first mold 11 through the conveying pipe 15, and the first mold 11 is engageable with the second mold 13.
具體而言，第一模具11內包括至少一連接孔111，而輸送管15則與連接孔111相連接，使得流體輸送單元17可透過輸送管15及連接孔111將流體輸送至第一模具11內。 Specifically, the first mold 11 includes at least one connecting hole 111, and the conveying pipe 15 is connected with the connecting hole 111, so that the fluid conveying unit 17 can transport the fluid to the first mold 11 through the conveying pipe 15 and the connecting hole 111. Inside.
在使用金屬板材成型裝置10時，通常會在第一模具11及第二模具13之間設置一金屬板材12，並透過第一模具11及第二模具13夾持金屬板材12。流體輸送單元17可將流體輸送至第一模具11與金屬板材12之間，並透過流體對金屬板材12施加壓力，使得金屬板材12朝第二模具13的方向變形。 When the sheet metal forming apparatus 10 is used, a metal plate 12 is usually disposed between the first mold 11 and the second mold 13, and the metal sheet 12 is sandwiched by the first mold 11 and the second mold 13. The fluid delivery unit 17 can transport the fluid between the first mold 11 and the metal sheet 12 and apply pressure to the metal sheet 12 through the fluid to deform the metal sheet 12 in the direction of the second mold 13.
具體來說第二模具13內包括一成型腔131，當第二模具13與第一模具11接合時，第一模具11的連接孔111將會與第二模具13的成型腔131相對。此外當第一模具11及第二模具13夾持金屬板材12時，金屬板材12將會完整的覆蓋第二模具13的成型腔131。流體輸送單元17輸送的流體將會對金屬板材12施壓，使得金屬板材12貼合在第二模具13內的成型腔131的表面，並完成金屬板材12的成型步驟，其中成型後的金屬板材12的形狀會與成型腔131的形狀相同。 Specifically, the second mold 13 includes a molding cavity 131. When the second mold 13 is engaged with the first mold 11, the connection hole 111 of the first mold 11 will be opposed to the molding cavity 131 of the second mold 13. Further, when the first mold 11 and the second mold 13 sandwich the metal sheet 12, the metal sheet 12 will completely cover the molding cavity 131 of the second mold 13. The fluid conveyed by the fluid conveying unit 17 will press the metal sheet 12 so that the metal sheet 12 fits on the surface of the molding cavity 131 in the second mold 13, and the forming step of the metal sheet 12 is completed, wherein the formed metal sheet is formed. The shape of 12 will be the same as that of the molding cavity 131.
在完成金屬板材12的成型步驟後，可將第一模具11與第二模具13分離，而後再將成型的金屬板材12由第二模具13的成型腔131內取出。然而第一模具11與成型的金屬板材12或第二模具13之間的氣體壓力很高，因此若直接分離第一模具11及第二模具13，則可能會產生危險，或者是導致第一模具11與第二模具13錯位。 After the forming step of the metal sheet 12 is completed, the first mold 11 and the second mold 13 can be separated, and then the formed metal sheet 12 can be taken out from the molding cavity 131 of the second mold 13. However, the gas pressure between the first mold 11 and the formed metal sheet 12 or the second mold 13 is high, so if the first mold 11 and the second mold 13 are directly separated, there may be a danger or the first mold may be caused. 11 is misaligned with the second mold 13.
為此在本創作一實施例中，可透過流體輸送單元17將第一模具11與金屬板材12之間的流體導出，並使得第一模具11與金屬板材12之間的壓力大於或等於外界的壓力，而後再將第一模具11及第二模具12分離。以避免第一模具11與第二模具13分離時，所可能導致的危險，或者是發生第一模具11與第二模具13錯位的情形。 To this end, in an embodiment of the present invention, the fluid between the first mold 11 and the metal sheet 12 can be discharged through the fluid transport unit 17, and the pressure between the first mold 11 and the metal sheet 12 is greater than or equal to the outside. The pressure is then separated from the first mold 11 and the second mold 12. The danger that may be caused when the first mold 11 is separated from the second mold 13 is avoided, or the first mold 11 and the second mold 13 are misaligned.
此外在實際製作時，成型的金屬板材12往往會緊貼在第二模具13的成型腔131上，使得成型的金屬板材12不易由第二模具13上取下。一般而言，通常會將第二模具13及成型的金屬板材12放置一段時間，使得第二模具13及成型的金屬板材12冷卻至一定的溫度後，再將成型的金屬板材12由第二模具13上取下。 In addition, in actual production, the formed metal sheet 12 tends to abut against the molding cavity 131 of the second mold 13, so that the formed metal sheet 12 is not easily removed from the second mold 13. Generally, the second mold 13 and the formed metal sheet 12 are usually placed for a period of time, so that the second mold 13 and the formed metal sheet 12 are cooled to a certain temperature, and then the formed metal sheet 12 is replaced by the second mold. Take it off on 13.
然而在第二模具13及金屬板材12在冷卻之後，成型的金屬板材12還是有可能無法由第二模具13的成型腔131內取出。此外在等待第二模具13及金屬板材12冷卻的過程中，往往需要花費許多的時間，進而增加製作成型的金屬板材12所花費的時間及製作成本。 However, after the second mold 13 and the metal sheet 12 are cooled, the formed metal sheet 12 may not be taken out from the molding cavity 131 of the second mold 13. Further, in the process of waiting for the cooling of the second mold 13 and the metal sheet 12, it takes a lot of time to increase the time and production cost of the formed metal sheet 12.
為了方便將成型的金屬板材12由第二模具13的成型腔131取下，並減少將成型的金屬板材12由第二模具13上取下所花費的時間。本創作揭露的流體輸送單元17除了可將流體輸送至第一模具11與金屬板材12之間，更可用以將第一模具11與金屬板材12之間的流體排出，使得第一模具11與金屬板材12之間的壓力略小於外界壓力，例如略小於1大氣壓。 In order to facilitate the removal of the formed metal sheet 12 from the molding cavity 131 of the second mold 13, the time taken to remove the formed metal sheet 12 from the second mold 13 is reduced. The fluid delivery unit 17 disclosed in the present disclosure can be used to discharge fluid between the first mold 11 and the metal sheet 12, and can also discharge the fluid between the first mold 11 and the metal sheet 12, so that the first mold 11 and the metal The pressure between the sheets 12 is slightly less than the external pressure, for example slightly less than 1 atmosphere.
具體來說本創作所述的流體輸送單元17在完成金屬板材12的成型步驟後，才會將第一模具11及金屬板材12之間的流體排出，並可進一步使得第一模具11與成型的金屬板材12之間形成負壓，以鬆動金屬板材 12與第二模具13之間的連接關係。此外當第一模具11與第二模具13分離時，第一模具11將會拉扯成型的金屬板材12，並使得成型的金屬板材12與第二模具13的成型腔131分離或鬆動，藉此將有利於將成型的金屬板材12由第二模具13上取下。 Specifically, the fluid transport unit 17 described in the present invention discharges the fluid between the first mold 11 and the metal sheet 12 after completing the forming step of the metal sheet 12, and further enables the first mold 11 and the formed mold. A negative pressure is formed between the metal sheets 12 to loosen the metal sheets The connection relationship between the 12 and the second mold 13. In addition, when the first mold 11 is separated from the second mold 13, the first mold 11 will pull the formed metal sheet 12, and the formed metal sheet 12 is separated or loosened from the molding cavity 131 of the second mold 13, thereby It is advantageous to remove the formed metal sheet 12 from the second mold 13.
然而在實際應用時，當第一模具11與金屬板材12之間為負壓時，有可能會導致第一模具11不易與第二模具13分離，或者是可能在第一模具11與第二模具13分離的過程中，造成金屬板材12產生變形。為了避免上述的情形發生，在本創作另一實施例中，可透過流體輸送單元17再次將流體輸送至第一模具11與金屬板材12之間，使得第一模具11與金屬板材12之間的壓力略大於或等於外界的壓力，並有利於開啟第一模具11及第二模具13。本創作所述金屬板材成型裝置10的動作方式，會在後續的實施例中詳細說明。 However, in practical applications, when the first mold 11 and the metal sheet 12 are under negative pressure, it may cause the first mold 11 to be difficult to separate from the second mold 13, or may be in the first mold 11 and the second mold. During the separation process, the metal sheet 12 is deformed. In order to avoid the above situation, in another embodiment of the present invention, the fluid can be again transported between the first mold 11 and the metal sheet 12 through the fluid delivery unit 17, such that the first mold 11 and the metal sheet 12 are The pressure is slightly greater than or equal to the external pressure, and is advantageous for opening the first mold 11 and the second mold 13. The mode of operation of the sheet metal forming apparatus 10 of the present invention will be described in detail in the following embodiments.
在本創作上述實施例中，第一模具11的連接孔111、下表面及/或內表面緊貼未成型的金屬板材12，而流體輸送單元17則經由輸送管15及連接孔111將流體輸送至第一模具11與金屬板材12之間，使得金屬板材12朝第二模具13的成型腔131變形，如第1圖所示。 In the above embodiment of the present creation, the connection hole 111, the lower surface and/or the inner surface of the first mold 11 abut against the unformed metal sheet 12, and the fluid delivery unit 17 delivers the fluid via the delivery tube 15 and the connection hole 111. Between the first mold 11 and the metal sheet 12, the metal sheet 12 is deformed toward the molding cavity 131 of the second mold 13, as shown in Fig. 1.
在不同實施例中，如第2圖所示，第一模具11內亦可包括一密封腔113，其中連接孔111連接密封腔113。當第一模具11與第二模具13相接合時，第一模具11的密封腔113將與第二模具13的成型腔131相對，並於密封腔113與成型腔131之間形成一密閉空間。 In different embodiments, as shown in FIG. 2, the first mold 11 may also include a sealing cavity 113 in which the connecting hole 111 is connected to the sealing cavity 113. When the first mold 11 and the second mold 13 are joined, the sealing cavity 113 of the first mold 11 will oppose the molding cavity 131 of the second mold 13, and a sealed space is formed between the sealing chamber 113 and the molding cavity 131.
此外當金屬板材12放置在第一模具11及第二模具13之間時，第一模具11的密封腔113與第二模具13的成型腔131將分別位於金屬板 材12的不同表面，其中金屬板材12將會完整的覆蓋密封腔113及成型腔131。當流體輸送單元17經由輸送管15及連接孔111將流體輸送至第一模具11的密封腔113時，密封腔113內的高壓流體將會對金屬板材12施壓，使得金屬板材12朝第二模具13的成型腔131的方向變形，直到金屬板材12完整的貼合在成型腔131的表面。此外流體輸送單元17更可將密封腔113內的流體排出，使得密封腔113內的壓力小於外界的壓力。 In addition, when the metal sheet 12 is placed between the first mold 11 and the second mold 13, the sealing cavity 113 of the first mold 11 and the molding cavity 131 of the second mold 13 are respectively located on the metal plate. The different surfaces of the material 12, wherein the metal sheet 12 will completely cover the sealing chamber 113 and the molding cavity 131. When the fluid delivery unit 17 delivers fluid to the sealed chamber 113 of the first mold 11 via the delivery tube 15 and the connection hole 111, the high pressure fluid in the sealed chamber 113 will press the metal sheet 12 such that the metal sheet 12 faces the second The direction of the molding cavity 131 of the mold 13 is deformed until the metal sheet 12 is completely attached to the surface of the molding cavity 131. In addition, the fluid delivery unit 17 can discharge the fluid in the sealed chamber 113 such that the pressure in the sealed chamber 113 is less than the external pressure.
請參閱第3圖，為本創作金屬板材成型裝置又一實施例的構造示意圖。如圖所示，本創作所述的金屬板材成型裝置20主要包括一第一模具11、一第二模具13、至少一輸送管15、一流體輸入單元27及一流體輸出單元29，其中流體輸入單元27及流體輸出單元29透過輸送管15連接第一模具11。 Please refer to FIG. 3, which is a schematic structural view of still another embodiment of the original metal sheet forming apparatus. As shown, the sheet metal forming apparatus 20 of the present invention mainly includes a first mold 11, a second mold 13, at least one conveying pipe 15, a fluid input unit 27, and a fluid output unit 29, wherein the fluid input The unit 27 and the fluid output unit 29 are connected to the first mold 11 through the conveying pipe 15.
在第1圖及第2圖所述的實施例中，主要透過單一個流體輸送單元17將流體輸送至第一模具11與金屬板材12之間，或者是將第一模具11與金屬板材12之間流體排出。 In the embodiments described in FIGS. 1 and 2, the fluid is mainly transported between the first mold 11 and the metal sheet 12 through a single fluid transport unit 17, or the first mold 11 and the metal sheet 12 are The fluid is discharged.
在本創作實施例中，則是透過流體輸入單元27將流體輸送至第一模具11與金屬板材12之間，使得金屬板材12朝第二模具13及/或成型腔131的方向變形，並緊貼在成型腔131的表面，以完成金屬板材12成型的步驟。 In the present embodiment, the fluid is delivered to the first mold 11 and the metal sheet 12 through the fluid input unit 27, so that the metal sheet 12 is deformed toward the second mold 13 and/or the molding cavity 131, and is tight. It is attached to the surface of the molding cavity 131 to complete the step of molding the metal sheet 12.
在完成金屬板材12的成型後，則可透過流體輸出單元29將第一模具11與金屬板材12之間流體排出，使得第一模具11與成型的金屬板材12之間的壓力略大於或等於外界的壓力，以利於分離第一模具11及第二模具13。 After the forming of the metal sheet 12 is completed, the fluid between the first mold 11 and the metal sheet 12 can be discharged through the fluid output unit 29, so that the pressure between the first mold 11 and the formed metal sheet 12 is slightly greater than or equal to the outside. The pressure is favorable to separate the first mold 11 and the second mold 13.
在本創作另一實施例中，流體輸出單元29可進一步排出第一模具11與金屬板材12之間的流體，使得兩者之間的壓力略小於外界壓力，例如小於1大氣壓。藉此第一模具11與成型的金屬板材12之間將會形成負壓，以鬆動金屬板材12與第二模具13之間的連接關係。此外當第一模具11與第二模具13分離時，第一模具11將會拉扯成型的金屬板材12，使得成型的金屬板材12與第二模具13的成型腔131的表面分離或鬆動，並有利於將成型的金屬板材12由第二模具13上取下。 In another embodiment of the present creation, the fluid output unit 29 may further discharge the fluid between the first mold 11 and the metal sheet 12 such that the pressure between the two is slightly less than the external pressure, such as less than 1 atmosphere. Thereby, a negative pressure is formed between the first mold 11 and the formed metal sheet 12 to loosen the connection relationship between the metal sheet 12 and the second mold 13. In addition, when the first mold 11 and the second mold 13 are separated, the first mold 11 will pull the formed metal sheet 12, so that the formed metal sheet 12 is separated or loosened from the surface of the molding cavity 131 of the second mold 13, and is advantageous. The formed metal sheet 12 is removed from the second mold 13.
然而在實際應用時，當第一模具11與金屬板材12之間為負壓時，有可能會導致第一模具11不易與第二模具13分離，或者是可能在第一模具11與第二模具13分離的過程中，造成金屬板材12產生變形。為了避免上述的情形發生，在本創作另一實施例中，可透過流體輸入單元27再次將流體輸送至第一模具11與金屬板材12之間，使得第一模具11與金屬板材12之間的壓力略大於或等於外界的壓力，並有利於開啟第一模具11及第二模具13。 However, in practical applications, when the first mold 11 and the metal sheet 12 are under negative pressure, it may cause the first mold 11 to be difficult to separate from the second mold 13, or may be in the first mold 11 and the second mold. During the separation process, the metal sheet 12 is deformed. In order to avoid the above situation, in another embodiment of the present invention, the fluid may be again transported between the first mold 11 and the metal sheet 12 through the fluid input unit 27 such that the first mold 11 and the metal sheet 12 are The pressure is slightly greater than or equal to the external pressure, and is advantageous for opening the first mold 11 and the second mold 13.
在本創作另一實施例中，亦可於流體輸入單元27與第一模具11之間設置一第一開關單元281，並於流體輸出單元29與第一模具11之間設置一第二開關單元283。當流體輸入單元27將流體輸送至第一模具11與金屬板材12之間時，可開啟(on)第一開關單元281，並關閉(off)第二開關單元283，使得流體不至於由流體輸出單元29洩漏。此外當流體輸出單元29將第一模具11與金屬板材12之間流體排出時，則可關閉(off)第一開關單元281，並開啟(on)第二開關單元283，使得外界的流體不至於由流體輸入單元27進入。 In another embodiment of the present invention, a first switch unit 281 may be disposed between the fluid input unit 27 and the first mold 11, and a second switch unit is disposed between the fluid output unit 29 and the first mold 11. 283. When the fluid input unit 27 delivers fluid between the first mold 11 and the metal sheet 12, the first switching unit 281 can be turned on, and the second switching unit 283 can be turned off so that the fluid is not discharged by the fluid. Unit 29 leaks. Further, when the fluid output unit 29 discharges the fluid between the first mold 11 and the metal sheet 12, the first switching unit 281 can be turned off, and the second switching unit 283 can be turned on, so that the external fluid is not prevented. Entered by the fluid input unit 27.
請參閱第4圖至第8圖，分別為本創作金屬板材成型裝置對金屬板材進行成型一實施例的動作示意圖。如第4圖所示，首先將金屬板材12放置在第一模具11與第二模具13之間，其中第一模具11及第二模具13會相互靠近，並夾持兩者之間的金屬板材12。例如第一模具11緊靠金屬板材12的上表面，使得金屬板材12與第一模具11的密封腔113形成密閉空間，此外第二模具13則緊靠金屬板材12的下表面，使得金屬板材12與第二模具13的成型腔131之間形成密閉空間。 Please refer to Fig. 4 to Fig. 8 for the action diagram of an embodiment of forming a sheet metal forming apparatus for forming a metal sheet. As shown in FIG. 4, the metal sheet 12 is first placed between the first mold 11 and the second mold 13, wherein the first mold 11 and the second mold 13 are close to each other and sandwich the metal sheet therebetween. 12. For example, the first mold 11 abuts against the upper surface of the metal sheet 12 such that the metal sheet 12 forms a closed space with the sealing cavity 113 of the first mold 11, and further the second mold 13 abuts against the lower surface of the metal sheet 12, so that the metal sheet 12 A sealed space is formed with the molding cavity 131 of the second mold 13.
一般而言，在將金屬板材12放置在第一模具11及第二模具13前，可預先加熱金屬板材12，並提高金屬板材12的溫度。此外第一模具11及第二模具13亦可保持在一定的溫度，當金屬板材12放置在第一模具11及/或第二模具13上時，第一模具11及第二模具13可持續加熱金屬板材12。 In general, before the metal sheet 12 is placed on the first mold 11 and the second mold 13, the metal sheet 12 can be heated in advance and the temperature of the metal sheet 12 can be increased. In addition, the first mold 11 and the second mold 13 can also be maintained at a certain temperature. When the metal sheet 12 is placed on the first mold 11 and/or the second mold 13, the first mold 11 and the second mold 13 can be continuously heated. Sheet metal 12.
當金屬板材12被放置在第一模具11及第二模具13之間後，流體輸入單元27將會經由輸送管15及連接孔111將流體輸送至第一模具11與金屬板材12之間，例如流體輸入單元27可將流體輸送至第一模具11的密封腔113內，並使得第一模具11與金屬板材12之間的第一壓力P1大於外界的壓力。如第5圖所示，流體輸入單元27輸入的流體將會對金屬板材12加壓，使得金屬板材12朝第二模具13及/或成型腔131的方向變形，直到金屬板材12完整的貼合在第二模具13的成型腔131的表面。 After the metal sheet 12 is placed between the first mold 11 and the second mold 13, the fluid input unit 27 will transport the fluid between the first mold 11 and the metal sheet 12 via the transfer tube 15 and the connection hole 111, for example, The fluid input unit 27 can deliver the fluid into the sealed cavity 113 of the first mold 11 such that the first pressure P1 between the first mold 11 and the metal sheet 12 is greater than the external pressure. As shown in Fig. 5, the fluid input from the fluid input unit 27 will pressurize the metal sheet 12 so that the metal sheet 12 is deformed toward the second mold 13 and/or the molding cavity 131 until the metal sheet 12 is completely fitted. At the surface of the molding cavity 131 of the second mold 13.
待金屬板材12完整的貼合在第二模具13的成型腔131的表面後，基本上便已完成金屬板材12成型的步驟。而後可關閉流體輸入單元27，使得流體輸入單元27不再將流體輸送至金屬板材12與第一模具11之間。待關閉流體輸入單元27後，便可開啟流體輸出單元29，並透過流體輸出單元 29將成型的金屬板材12與第一模具11之間的流體排出，如第6圖所示。 After the metal sheet 12 is completely attached to the surface of the molding cavity 131 of the second mold 13, the step of molding the metal sheet 12 is substantially completed. The fluid input unit 27 can then be closed such that the fluid input unit 27 no longer delivers fluid between the sheet metal 12 and the first mold 11. After the fluid input unit 27 is closed, the fluid output unit 29 can be turned on and the fluid output unit is transmitted. The fluid between the formed metal sheet 12 and the first mold 11 is discharged as shown in Fig. 6.
在本創作一實施例中，流體輸出單元29可將金屬板材12與第一模具11之間的流體排出，使得兩者之間的壓力略大於或等於外界的壓力，並有利於分離第一模具11及第二模具13。 In an embodiment of the present invention, the fluid output unit 29 can discharge the fluid between the metal sheet 12 and the first mold 11 such that the pressure between the two is slightly greater than or equal to the external pressure, and facilitates separation of the first mold. 11 and the second mold 13.
在本創作另一實施例中，流體輸出單元29亦可進一步排出金屬板材12與第一模具11之間的流體，使得成型的金屬板材12與第一模具11之間的第二壓力P2小於外界的壓力，例如1大氣壓。由於第一模具11與金屬板材12之間的壓力略小於外界的壓力，因此會約略將金屬板材12朝第一模具11的方式吸引，藉此以鬆動第一模具11與金屬板材12之間的連接關係。 In another embodiment of the present invention, the fluid output unit 29 can further discharge the fluid between the metal sheet 12 and the first mold 11 such that the second pressure P2 between the formed metal sheet 12 and the first mold 11 is smaller than the outside. The pressure, for example, 1 atmosphere. Since the pressure between the first mold 11 and the metal sheet 12 is slightly smaller than the external pressure, the metal sheet 12 is approximately attracted toward the first mold 11, thereby loosening between the first mold 11 and the metal sheet 12. Connection relationship.
而後可使得第一模具11及第二模具13相互分離，此時由於第一模具11與成型的金屬板材12之間會形成負壓，例如兩者之間的壓力小於外界的壓力。因此當第一模具11與第二模具13分離時，第一模具11將會吸附及拉動成型的金屬板材12，並可能會帶動成型的金屬板材12朝第一模具11的方向移動，或者是鬆動成型的金屬板材12與第二模具13及/或成型腔131之間的連接關係。藉此將有利於將成型的金屬板材12由第二模具13及/或成型腔131取下，並可有效縮短金屬板材12的製作及/或脫模所花費的時間。 Then, the first mold 11 and the second mold 13 can be separated from each other. At this time, a negative pressure is formed between the first mold 11 and the formed metal sheet 12, for example, the pressure between the two is smaller than the external pressure. Therefore, when the first mold 11 and the second mold 13 are separated, the first mold 11 will adsorb and pull the formed metal sheet 12, and may move the formed metal sheet 12 toward the first mold 11 or be loose. The connection relationship between the formed metal sheet 12 and the second mold 13 and/or the molding cavity 131. Thereby, it will be advantageous to remove the formed metal sheet 12 from the second mold 13 and/or the molding cavity 131, and the time taken for the production and/or demolding of the metal sheet 12 can be effectively shortened.
然而在實際應用時，當第一模具11與金屬板材12之間為負壓時，將有可能會導致第一模具11不易與第二模具13分離，或者是可能在第一模具11與第二模具13分離的過程中，造成金屬板材12產生變形。為了避免上述的情形發生，在本創作另一實施例中，可透過流體輸入單元27再次將流體輸送至第一模具11與金屬板材12之間，使得第一模具11與金屬板材12之間的第三壓力P3略大於或等於外界的壓力，如第7圖所示。而後便可 將第一模具11及第二模具13分離，如第8圖所示。 However, in practical applications, when the first mold 11 and the metal sheet 12 are under negative pressure, it may cause the first mold 11 to be difficult to separate from the second mold 13, or may be in the first mold 11 and the second. During the separation of the mold 13, the metal sheet 12 is deformed. In order to avoid the above situation, in another embodiment of the present invention, the fluid may be again transported between the first mold 11 and the metal sheet 12 through the fluid input unit 27 such that the first mold 11 and the metal sheet 12 are The third pressure P3 is slightly greater than or equal to the external pressure, as shown in FIG. Then you can The first mold 11 and the second mold 13 are separated as shown in Fig. 8.
在本創作上述第4至8圖所述的步驟流程中，主要是以第3圖所述的構造進行說明。然而在實際應用時亦可以第1圖或第2圖所示的構造，進行上述第4至8圖所述的步驟流程，同樣可完成金屬板材12成型的步驟，並同樣有利於將成型的金屬板材12由第二模具13及/或成型腔131上取下。 In the flow of the steps described in the above-described fourth to eighth drawings, the structure described in FIG. 3 is mainly explained. However, in the actual application, the steps shown in the above FIGS. 4 to 8 can also be performed in the configuration shown in FIG. 1 or FIG. 2, and the step of forming the metal sheet 12 can be completed, and the formed metal is also favored. The sheet 12 is removed from the second mold 13 and/or the forming cavity 131.
第1圖及第2圖所述的流體輸送單元17可將流體輸送至第一模具11與金屬板材12之間，使得金屬板材12完整的貼附在第二模具13的成型腔131的表面。待完成金屬板材12的成型步驟後，流體輸送單元17更可將第一模具11與成型的金屬板材12之間的流體排出，使得第一模具11與成型的金屬板材12之間的壓力略小於外界的壓力，或者是使得第一模具11與金屬板材12之間的壓力略大於或等於外界的壓力。藉此有利於鬆動金屬板材12與第二模具13之間的連接關係，以利於將成型的金屬板材12由第二模具13及/或成型腔131上取下，及利於分離第一模具11與第二模具13。 The fluid delivery unit 17 described in FIGS. 1 and 2 can transport fluid between the first mold 11 and the metal sheet 12 such that the metal sheet 12 is completely attached to the surface of the molding cavity 131 of the second mold 13. After the forming step of the metal sheet 12 is completed, the fluid conveying unit 17 can discharge the fluid between the first mold 11 and the formed metal sheet 12, so that the pressure between the first mold 11 and the formed metal sheet 12 is slightly smaller. The external pressure is such that the pressure between the first mold 11 and the metal sheet 12 is slightly greater than or equal to the external pressure. Thereby, the connection relationship between the metal sheet 12 and the second mold 13 is loosened, so as to facilitate the removal of the formed metal sheet 12 from the second mold 13 and/or the molding cavity 131, and facilitate separation of the first mold 11 and The second mold 13.
