    摘要： The invention relates to a closing unit for tools to be pressed together against opening forces having two tool carriers which can be displaced towards one another. In accordance with the invention, there are two jaws engaging over the tool carrier plates at the side in each case in a closed position while building up a bias. The closing unit is advantageously designed in the form of bias modules for tools.

    摘要： Internal high pressure forming at present takes place by exerting a pressure between sheet metal blanks fixed by a marginal weld. It has already been proposed to deform under high internal pressure sheet metal blanks merely placed on one another in a combined clamping and sealing die. Problems arise with regards to the sealing and material flow. Thus, to overcome the aforementioned disadvantages, the invention proposes a method for forming at least one workpiece under high liquid or hydraulic pressure, in which the workpiece, during pressure build-up, is initially marginally clamped in per se known manner and in the final phase of forming to the desired final shape of the workpiece (sizing) the marginal area of the workpiece is freed. It also proposes an apparatus (1) for the hydraulic forming of at least one workpiece by means of a forming die (21) having an upper and a lower part (26, 24), which clamp the workpiece in marginal areas whilst allowing an also differing material flow, the forming die (21) being surrounded by a pressure casing (2) separate therefrom.

    摘要： A sheet metal blank positioned upon a lower die is wrapped around an upper die as the upper die is moved down to a closed position by an outer slide, the blank being clamped between the upper and lower dies whereby the periphery of the blank is gripped between a male and female bead mounted all around a part print cavity in the upper and lower dies, respectively. The outer slide then dwells while an inner slide moves down, engaging and actuating cylinder assemblies, causing hydraulic fluid to be forced into a region between the clamped blank and the lower die, the blank being formed into a part print cavity defined in the upper die. The male bead exerts varying control on the sheet to allow it to stretch across portions of the cavity while flowing into other portions of the cavity. A locking mechanism prevents the bending of the dies and holds the dies in a closed position thereby assisting the engagement of the male bead with the female bead. As a safety feature, the mechanism is configured to automatically open when the die cavity is moved up. The locking mechanism allows the use of high pressures to make large parts, such as car hoods, doors, deck lids, and quarter panels in conventional currently available double action presses.

    摘要： A self-contained apparatus for forming metal sheet is adapted for operation within a standard double action press having a base and outer and inner vertically reciprocating slides and includes a basic die mountable to the press and specific tooling replaceably mountable to the basic die. The basic die includes an upper shoe mountable to the outer slide, a lower shoe mountable atop the base and hydraulic cylinder assemblies connected to the lower shoe and mechanically actuatable by the inner slide for providing pressurized fluid to the specific tooling. The specific tooling includes mating upper and lower dies connected to the corresponding upper and lower shoes and movable between open and closed positions. A sheet metal blank positioned upon the lower die is wrapped around the lower die as the upper die is moved down to a closed position by the outer slide, the blank being clamped between the upper and lower dies whereby the periphery of the blank is securely gripped by gripper steels mounted all around a part print cavity in the upper die. The outer slide then dwells while the inner slide moves down, engaging and actuating the cylinder assemblies, causing hydraulic fluid to be forced into a region between the clamped blank and the lower die, the blank being 100% stretch formed into the part print cavity defined in the upper die.

    摘要： The specification and drawings disclose a method and apparatus for forming dish-shaped metal elements through the use of a combined fluid pressure and sheet tensioning process. The disclosed method is particularly intended for forming dish-shpaed sheet metal elements having a length substantially greater than their width and includes applying a longitudinal tension to the sheet while permitting the lateral edges to move toward one another substantially unconstrained while the fulid pressure acts to bow the sheet. The disclosed apparatus includes a flexible frame of generally eliptical shape which clamps to the edge of the sheet. The frame is arranged so that as the sheet bows outwardly, the lateral sides of the frame are pulled inwardly driving the ends of the frame apart.
