摘要： An apparatus for forming production parts under internal high-pressure conditions, has an internal high-pressure forming tool which includes a top and a bottom die half and also can produce a fluidic internal high pressure inside the closed die. A support plate is movable in a reciprocating manner relative to a head plate, and a supporting means is pushed into the intermediate space produced in the closed state of the die between the lowered support plate and the head plate (9) and supports the two plates against one another during the forming operation while maintaining the distance between them.

摘要： The invention relates to a method and a device for manufacturing T-pieces from an unbranched starting piece of pipe by means of internal high-pressure forming (IHF). For this purpose, the starting piece of pipe is placed in a two-part forming tool which gives the shape, can be opened and closed, surrounds the starting piece of pipe, and has a cutout corresponding to the desired shape of the T-shaped pipe branch. Placed in a sealing manner against the two open end faces of the inserted starting piece of pipe in each case is a plunger which is movable in the forming tool and can be pushed axially into the forming took in each case by a pressure cylinder. The interior of the starting piece of pipe is filled with pressure fluid by means of an opening in at least one of the plungers, prior to being placed on the plungers in a sealing manner. A fluid high-pressure is built up by pushing the plungers axially into the forming tool with high force and, thus initiated, by pushing pipe wall material axially towards the forming point, the pipe wall material is pressed into the cutout in the forming tool and the T-shaped branch is thus shaped. In order to be able to manufacture T-pieces with a curved branch, the end face of the T-shaped cutout for the pipe branch is supported with controllable force by means of a flexible mandrel.

摘要： The invention relates to a device for forming a peripherally closed hollow profiled element (1) by means of fluidic internal high pressure. The device contains an axial plug (4) for sealing off the hollow profiled element (1) on the end face, said axial plug possessing an axial passage duct (5) supplying pressure fluid. The axial plug (4) has a sealing body which possesses on its end face (19) a trough-like depression (20), the peripheral wall (21) of which can be spread open radially elastically, within the hollow profiled element (1), by means of pressure fluid, until said wall comes to bear sealingly against the inner wall (22) of the hollow profiled element (1). To maintain the sealability of the device permanently, the axial plug (4) is to have a plug head (8), formed by an annular collar (10) and a narrowed extension (11) adjoining the latter toward the end face (7) of the head (8), and, on its plug body (9), a radial peripheral stop for bearing against the closing edge (12) of the hollowed profiled element end (13). The sealing body, designed as a sealing ring (17), is fixed on the extension (11), the margin (28) of the annular collar (10) projecting peripherally beyond the outside (27) of the sealing ring (17) at least one point in the radial direction.
摘要翻译：本发明涉及一种用于通过流体内部高压形成外围封闭的中空型材元件（1）的装置。该装置包括用于密封端面上的中空型材元件（1）的轴向插头（4），所述轴向插塞具有供应压力流体的轴向通道导管（5）。轴向插头（4）具有密封体，该密封体在其端面（19）上具有槽状凹部（20），该凹槽可以在中空型材元件（1）内径向弹性地展开），通过压力流体，直到所述壁密封地抵靠中空型材元件（1）的内壁（22）。为了永久地保持设备的密封性，轴向插头（4）具有由环形套环（10）形成的插塞头（8）和与端子（7）相邻的插入头（11）的狭窄延伸部（11）的头部（8），并且在其塞体（9）上具有用于抵靠中空的异形元件端部（13）的闭合边缘（12）的径向外周止动件。被设计为密封环（17）的密封体固定在延伸部（11）上，环形套环（10）的边缘（28）周向地突出超过密封环（17）的外部（27）径向方向最少一点。
