摘要： The invention relates to a forming tool for forming sheet blanks in a diaphragm press (1) of the kind comprising a openable, closed pressure chamber (4), which is divided in a gas and liquid tight manner by means of a flexible diaphragm (5). The forming tool (6) is adapted to be arranged on one side of the diaphragm and a sheet blank (11) to be formed is adapted to be arranged between the forming tool and the diaphragm. The opposite side of the diaphragm is adapted to be pressurised by a fluid being supplied at high pressure to cause the flexible diaphragm to deform and, thus, the sheet blank to be pressed against the forming tool. The forming tool (6) comprises an elongate cutting and flanging tool (7) along at least part of its periphery and/or around an intended opening in the sheet blank (11). The cutting and flanging tool (7) has a cutting edge and is displaceable, with the aid of actuating means, in an elongate slot in the forming tool towards and away from the plane of the diaphragm (5). At a first pressing pressure, the sheet blank is caused to be cut off against the cutting edge and, as the pressure is continuously increased, the cutting and flanging tool is caused to be displaced into the slot in the forming tool, so that the peripheral edge of the sheet blank is deformed towards the interior of the slot during forming of a flanged edge.
摘要翻译：本发明涉及一种用于在隔膜冲压机（1）中形成板坯的成型工具，该隔膜压制机包括一个可打开的封闭压力室（4），其通过柔性隔膜（5）以气液密封的方式被分开）。成形工具（6）适于布置在隔膜的一侧，并且待成形的板坯（11）适于布置在成形工具和隔膜之间。隔膜的相对侧适于由在高压下供应的流体加压，以使柔性隔膜变形，并因此使板坯压靠在成型工具上。成形工具（6）沿着其周边的至少一部分和/或围绕板坯（11）中的预期开口包括细长的切割和折边工具（7）。切割和凸缘工具（7）具有切割边缘，并且可借助于致动装置在成形工具中的细长槽中朝向和远离隔膜（5）的平面移动。在第一按压压力下，使片材坯料相对于切割边缘切断，并且随着压力不断增加，使得切割和翻边工具移位到成形工具中的狭槽中，使得外围在形成法兰边缘的过程中，片材坯料的边缘朝向槽的内部变形。

摘要： A device for pressure treatment of wood elements comprises a pressure chamber (1) for accommodating the wood elements (5a, 5b, 5c) which are to be treated. The pressure chamber also accommodates a pressure medium which surrounds the wood elements on more than one side and, at least before the pressurization, a secondary medium in the form of a fluid. When the pressure medium is pressurized, the wood elements are subjected to a multilateral pressure, whereby they are permanently compressed. Further, the pressure chamber is provided with means (11a, 11b) for controlling the quantity of secondary medium which penetrates into the wood during the treatment. These means may consist of evacuating valves (11a) or of casings (11b) which surround the wood elements and which are impenetrable to the secondary medium.

摘要： The invention relates to a method for forming of sheet metal parts, wherein above or below a fixed tool there is placed a sheet, against the outer parts of which, at the initial stage of a sheet-forming sequence, a force (FH) is applied from a force generating means (4). The invention is characterized in that the initial force (FH) (the blank holder force) is applied through an elastic diaphragm (5) and is given such a magnitude that the formation of folds on the sheet (1) is avoided at the initial stage, when a hydraulic force (Fp) is applied to the sheet (1) through the elastic diaphragm (5). When the latter force (FP) has reached a suitable pressure, the former force (FH) is gradually decreased.

摘要： A method for treatment of one or more wood elements (4) by pressurization comprises the steps of embedding the wood elements into a pressure medium (8), of increasing the pressure in the pressure medium, whereby the wood element is compressed by transmitting the pressure via the pressure medium to the wood elements, and of reducing the pressure in the pressure medium, whereby the wood element is relieved. During the treatment, liquid present in the wood elements (4) is driven out therefrom. The pressure medium (8) comprises a plurality of solid bodies with intermediate spaces. The solid bodies transmit the pressure to the wood elements such that a pressure difference arises between the wood elements and said spaces, which pressure difference drives out the liquid. During the relief phase, the wood elements substantially resume their original shape. The method can also be used for introducing impregnating liquid into the wood elements after the liquid expulsion.
摘要翻译：通过加压处理一个或多个木质元件（4）的方法包括以下步骤：将木材元件嵌入压力介质（8）中，增加压力介质中的压力，从而通过传递压力来压缩木质元件通过压力介质到达木质元件，并降低压力介质中的压力，由此木材元件被释放。在处理期间，存在于木质元件（4）中的液体被驱出。压力介质（8）包括具有中间空间的多个固体。固体将压力传递到木质元件，使得木材元件和所述空间之间产生压力差，该压力差驱出液体。在浮雕阶段期间，木质元素基本恢复其原始形状。该方法还可用于在液体排出之后将浸渍液引入木质元素中。

摘要： A device for holding, in a braking manner, a preferably sheet-formed blank (31) when forming the blank in a fluid cell press. During the forming, a hydraulic forming pressure is applied, via an elastic diaphragm (4), to one side of the blank. The device comprises first means (18) for generating a hydraulic blank holder pressure and second means (15, 16, 17a) for supplying this pressure to a movable member (14) and maintaining this pressure. The movable member is adapted, as long as the blank holder pressure is maintained, to hold part of the blank in a braking manner against a support (13). To improve the forming result, the device comprises means (20) which, under the direct influence of the forming pressure, reduce the blank holder pressure when the forming pressure attains a predetermined value.
