    • Disclosed herein is a sheet metal stamping device and method for substantially inhibiting recoil from a neutral stamped position of a scrap part region. A sheet metal stamping device for stamping a sheet metal part comprising a first die body and a second is provided wherein the first die body and the second die body are in operable communication for forming the sheet metal part from a sheet metal blank. The sheet metal part includes at least one scrap region formed therein which is prone to recoil from a neutral stamped position. The first die body and the second die body have complementary elongate bead-forming regions located for forming an elongate bead region in the scrap region. And, the elongate bead-forming regions are configured such that the elongate bead substantially inhibits recoil or springback of the scrap region from the neutral stamped position when the scrap region is severed from the part. A method of stamping a sheet metal part having at least one scrap region prone to recoil formed therein utilizing the device and severing the scrap region is also disclosed.
    • 本文公开了一种用于从废料部分区域的中立冲压位置基本上抑制反冲的钣金冲压装置和方法。 提供了一种用于冲压包括第一模具本体和第二模具的金属片的金属板冲压装置,其中,第一模具主体和第二模具主体可操作地连接,用于从金属板坯形成金属片。 钣金件包括形成在其中的至少一个废料区域,其易于从中立的冲压位置反冲。 第一模具体和第二模具体具有互补的细长的胎圈形成区域,用于在废料区域中形成细长的胎圈区域。 并且,细长的胎圈形成区域被构造成使得当废料区域从该零件切断时,细长的胎圈基本上阻止废料区域从中立的冲压位置的后退或回弹。 还公开了一种使用该装置冲压具有至少一个容易发生反冲的废料区域的金属片部件的方法,并且切断废料区域。

    • Disclosed herein is a sheet metal stamping device and methods for reducing the size of a blank required for producing a stamped part therefrom than is conventionally possible. The device utilizes an intermediate clamp section with projections having clamping formations located thereon which complement clamping formations located on a first die section. The intermediate clamp section projections allow for the use of a smaller blank size as less addendum material is required to secure the blank during the stamping process. The blank is secured using the intermediate clamp section and the first die section prior to the second die section engaging the blank to stamp the part. In some embodiments, retention beads resultant from the clamping process may remain in the stamped part, that being inside a trim line. Furthermore, in some embodiments, a blank shifter may be provided to locate the blank between the die sections prior to clamping. In other embodiments, more than one complementary pair of clamping formations may be provided. Furthermore, in some embodiments a trim line cutter may be provided.
    • 本文公开了一种金属冲压装置以及用于从传统可能的方式减小制造冲压部件所需的坯料尺寸的方法。 该装置利用具有位于其上的夹持结构的突起的中间夹具部分,其对位于第一模具部分上的夹紧结构进行补充。 中间夹具部分突起允许使用较小的坯料尺寸,因为在冲压过程中需要更少的齿顶材料来固定坯件。 在第二模具部分接合坯件之前,使用中间夹紧部分和第一模具部分来固定坯件以压印该零件。 在一些实施例中,由夹紧过程产生的保留珠可以保留在冲压部分中,即在修剪线内。 此外,在一些实施例中,可以提供空白移位器以在夹紧之前将坯料定位在模具部分之间。 在其它实施例中,可以提供多于一对的互补的夹持结构对。 此外,在一些实施例中,可以提供修剪线切割器。
