    摘要： A forming tool apparatus is provided for forming an article having a negative draft angle that locks the formed article within the forming tool. An insert, which is disposed within a recess defined in a forming surface of the forming tool, has a surface that cooperates with the forming surface of the forming tool to shape a metal blank into a desired final shape. In particular, the surface of the insert is shaped to define the negative draft angle feature of the formed article. Subsequent to forming the article, a linear-drive mechanism is activated to withdraw the insert away from the formed article, and thereby unlock the formed article from the tool. The formed article is then extracted from the tool along an extraction direction that is other than parallel to the direction along which the insert is driven.

    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 reservoir pan mounted atop the base, and hydraulic cylinder assemblies mounted with the pan 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 upper shoe and base, respectively, 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.

    摘要翻译： 用于形成金属板的独立装置适于在具有基部和外部和内部和垂直往复滑动的标准双作用压力机中操作，并且包括可安装到压力机的基本模具和可替换地安装到基本模具的特定工具。 基本模具包括可安装到外部滑动件的上部滑块，安装在底部顶部的储存器盘以及安装有盘的液压缸组件，并且可由内部滑块机械地致动，用于向特定工具提供加压流体。 具体的工具包括分别连接到上鞋和底座的上模和下模，并可在打开和关闭位置之间移动。 当上模通过外滑动件向下移动到关闭位置时，位于下模上的金属板坯被卷绕在下模上，坯料夹在上模和下模之间，从而使坯料的周边牢固地夹紧 通过夹持器将钢丝安装在上模的一部分印刷腔周围。 然后，外滑块在内滑块向下移动时接合并致动气缸组件，导致液压流体被迫进入被夹紧的坯件和下模之间的区域中，坯件被100％拉伸成形成在部件印刷腔中 在上模。

    摘要： Each of the metallic units has a concave portion bounded by a peripheral edge which has a predetermined shape. The apparatus includes an upper member and a lower member and a tool is adapted to be mounted on the upper or lower member. The tool comprises a wall-like structure having a bottom edge which defines a shape corresponding with the predetermined shape. The upper member and lower member are arranged to be movable relative one to the other, and a workpiece is placed between the two members and the members are brought together until the tool is clamped abuts the workpiece so that the tool and workpiece are clamped together in airtight engagement. Air under pressure is applied under the workpiece to form the workpiece into a concave shape.
