    摘要: The invention is directed to a forming device, especially internal high-pressure forming device, with a multiple-part forming tool and a clamping device which holds the parts of the forming tool together against the deforming action. In the novel forming device, according to the invention, the clamping device and/or the forming tool have/has at least one counter-clamping device which compensates at least partially for deformations of the mold cavity during forming. The possibility of compensation according to the invention makes it possible to construct the clamping and/or forming tool parts in a less solid manner.

    摘要: A method and apparatus using pneumatic pressure and reduced, controlled clamping pressure to provide reliable, high speed pneumatic forming of thin foil workpieces at ambient temperatures without lubricants or cull plates. Forming elements are provided which incorporate a combination of surfaces and features which enable the reduced, controlled net clamping pressures for forming thin foil workpieces, and control of material slip during forming. Thin foil workpieces formed therewith have reduced incidence of tearing and wrinkling of the foil material. The method is capable of fast cycle times and produces minimal waste.

    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. A basic die is mountable to the press and specific tooling is replaceably mountable to the basic die. The basic die includes a riser, a manifold and hydraulic cylinder assemblies. A sheet metal blank is positioned on the lower die and is 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. The cylinder assemblies cause hydraulic fluid to be forced into a region between the clamped blank and the lower die and form the blank in the part print cavity. 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 double action presses.

    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。 基本模具可安装到压机上,特定的模具可更换地安装到基本模具上。 基本模具包括立管,歧管和液压缸组件。 金属板坯被定位在下模上并且被夹在上模和下模之间,由此坯料的周边被夹在安装在零件印刷腔周围的阳和阴珠之间。 气缸组件使得液压流体被迫进入被夹紧的坯件和下模具之间的区域中并在部件印刷腔中形成坯件。 凸形凸起对片材进行变化的控制,以允许其在流入空腔的其它部分的同时在空腔的一部分上拉伸。 锁定机构防止模具的弯曲并将模具保持在关闭位置,从而有助于凸形凸缘与凹形凸缘的接合。 作为安全特征,该机构配置成当模腔向上移动时自动打开。 锁定机构允许使用高压来制造大型部件,例如传统的双作用压力机中的汽车罩,门,甲板盖和四分之一片。

    摘要: A method of bonding and shaping a plurality of pieces of material disposed in a fluid tight container includes providing a housing having components with different coefficients of thermal expansion. The container is positioned between upper and lower sections of the housing. The housing is then enclosed in an autoclave. The fluid in the autoclave and housing is heated with a resulting increase in the fluid pressure in the autoclave and housing. As the temperature and pressure in the housing is increased, the joint between the container and the housing sections is sealed by pressing the upper and lower sections of the housing against the container under the influence of forces resulting from different amounts of of thermal expansion of components of the housing. Thereafter, the fluid pressure in the autoclave is increased. Since the joint between the housing and the container has been sealed, the further increase in fluid pressure is applied to only the upper side of the container. This forces the container downwardly against a forming surface having a configuration corresponding to a desired configuration of the pieces of material.

    摘要: Apparatus and method for forming a peripheral skirt on a workpiece of metal or other ductile material with reduced pleating of its peripheral edge. The concentric mating male and female dies of the prior art are provided, and in addition at least one drawbar concentric with, outside of, and generally beside the male die guides the outer periphery of the workpiece as the dies are urged together, preventing the outer margin of the workpiece from being folded under and propagating pleats. The drawbars also assist in clamping the outer margin of the workpiece between the dies when the central portion of the workpiece is to be expanded by the application of fluid forming pressure.

    摘要: A multiple groove pulley is formed from a cup-shaped blank by an apparatus and method in which axially displaceable segmental shaping rings are positioned at axially predetermined positions along the wall of the blank. Fluid pressure communicated to the interior of the blank expands the wall of the blank into contact with the shaping rings and at least one of the shaping rings is independently movable in an axial direction while the blank is compressed for simultaneous formation of the grooves. A sleeve member is movable axially over at least one of the shaping rings to resist radial movement of the segments while at the same time permitting full compression of the blank.
