    • The apparatus and method for vacuum forming a film employs a vacuum forming apparatus to form a raw film material into a patterned film material having a concavo-convex pattern. An apparatus for vacuum forming a film comprises a hollow cylindrical roller having an inner surface, an outer surface, and a plurality of vacuum passageways defined therein between the inner and outer surfaces. A mesh layer is disposed around the outer surface of the roller, forming an intermediate layer between the roller and an outer forming layer disposed around the backing layer. The forming layer is a sheet layer of a material having a having a pattern-forming array of apertures defined therethrough. A vacuum applied to an area of the inner surface of the roller draws areas of a heated film material inward against the mesh layer, forming the film material into a concavo-convex pattern.
    • 用于真空成膜的装置和方法采用真空成型装置将原料薄膜材料形成为具有凹凸图案的图案化薄膜材料。 用于真空成型薄膜的设备包括具有内表面,外表面和限定在其内表面和外表面之间的多个真空通道的中空圆柱滚子。 网格层设置在辊的外表面周围,在辊和设置在背衬层周围的外部成形层之间形成中间层。 形成层是具有通过其形成的图案形成阵列的材料的片层。 施加到辊的内表面的区域的真空将加热的膜材料的区域向内抵靠网格层,将膜材料形成为凹凸图案。

    • There are provided an apparatus and an associated method for manufacturing superplastically formed structural assemblies from preforms. The apparatus includes first and second co-operable dies structured to define a die cavity therebetween for at least partially receiving the preform, at least one heater in thermal communication with the die cavity for heating the preform to a forming temperature, and at least one injector in fluid communication with the die cavity. The injector is structured for injecting pressurized gas into the die cavity to urge the preform against one of the dies to form the preform into the structural assembly. Further, at least one of the injectors is structured for injecting a quenchant into the die cavity to thereby heat treat the structural assembly while distortion of the structural assembly is being at least partially restrained by at least one of the dies.
    • 提供了一种用于从预制件制造超塑性结构组件的装置和相关方法。 该装置包括第一和第二可共同操作的模具,其被构造成在其间限定模腔,用于至少部分地容纳预成型件;至少一个与模腔热连通的加热器,用于将预成型件加热至成形温度;以及至少一个喷射器 与模腔流体连通。 喷射器构造成用于将加压气体注入模腔中,以将预成型件推压到模具中的一个上,以将预制件形成到结构组件中。 此外,喷射器中的至少一个被构造用于将淬火剂喷射到模腔中,从而热处理结构组件,同时结构组件的变形至少部分地被至少一个模具限制。
