摘要： A metal forming apparatus characterized by rapid cooling includes a forming tool having a first portion defining a forming surface and a second portion defining a cavity for a working gas. A plurality of fins are in conductive heat transfer relationship with the forming tool. The metal forming apparatus enables a high thermal efficiency mode of operation when the effect of the fins is negated for use during metal forming operation, and a rapid cooling mode for use in preparing for tool maintenance. A corresponding method is also provided.
摘要翻译：特征在于快速冷却的金属成形设备包括具有限定成形表面的第一部分和限定工作气体的空腔的第二部分的成形工具。多个翅片与成形工具具有导热性传热关系。当在金属成形操作期间不使用翅片的效果以及用于准备工具维护的快速冷却模式时，金属成形装置能够实现高热效率的操作模式。还提供了相应的方法。

摘要： Work hardened sheets of formable metal are annealed by thermal conduction and heated to a forming temperature. In a preferred embodiment, the sheet is placed on a flat surface of a heated lower platen to partially heat and soften the sheet and an opposing heated upper platen is brought close enough to the sheet to contribute heat but not to constrain the sheet as it expands. The platens are then both brought close to the sheet to heat it to its forming temperature largely by thermal conduction.
摘要翻译：成形金属的加工硬化片材通过热传导退火并加热至成形温度。在优选实施例中，片材被放置在加热的下压板的平坦表面上以部分地加热和软化片材，并且相对的加热的上压板足够靠近片材以产生热量，但是不会在片材膨胀时限制片材。然后将压板两者都靠近板材加热，以通过热传导将其加热到其成形温度。

摘要： Lightweight grids for lead-sulfuric acid type storage batteries are characterized by their laminated reticulated open meshed portions for retaining chemically active, lead-based paste materials. The laminated portions comprise a support layer of a rigid or semi-rigid plastic, an electrically conductive lead foil layer coextensive with the plastic layer, and a sulfuric acid resistant adhesive bonding layer between the plastic support and foil layers. In a preferred embodiment, the grid wires and nodes are twisted relative to the principal plane of the grid so that the lead foil layer is oriented to face the grid header portion and act as a ledge for retaining a desired battery paste. Such laminated grids may be rapidly and inexpensively formed by expanded metal processes of the type used to make battery grids made entirely of lead.
摘要翻译：铅酸蓄电池的轻质网格的特征在于它们的层叠网状开口网状部分，用于保留化学活性的铅基糊料。层压部分包括刚性或半刚性塑料的支撑层，与塑料层共同延伸的导电铅箔层以及在塑料支撑体和箔层之间的耐硫酸粘合层。在优选实施例中，栅格线和节点相对于栅格的主平面扭曲，使得引线箔层被定向成面对栅格集管部分并且用作用于保持期望的电池浆料的壁架。这种层压网格可以通过用于制造完全由铅制成的电池网格的类型的扩展金属工艺快速且廉价地形成。
