Embodiment Construction

[0016] The metal forming process described herein can be used to form complex metal parts in an effective manner that reduces the amount of scrap metal while maintaining the structural integrity of the complex metal parts. Typically, multiple individual metal blanks are welded to one or more sheet metal coils to produce welded coil assemblies. The welded coil assembly (in coiled or uncoiled form) can then be fed through progressive stamping equipment to form complex metal parts. Although the following description is provided in the context of forming exemplary automobile parts, it should be understood that the metal forming process and welded coil assembly described below may alternatively be used to form non-automotive parts, including for aircraft, boats, ships, Parts of agricultural equipment, RVs, and facilities are not listed here.

[0017] reference figure 1 , Which shows an exemplary metal forming process 10, which can be used to manufacture automotive parts process, in t...

Abstract

A metal forming process and welded coil assembly (100, 130, 160) that may be used to form complex metal components in a manner that is efficient, reduces scrap material, and maintains the structural integrity of the components. Generally, a number of individual metal blanks (102, 132, 162) are welded to one or more sheet metal coils (104, 106, 134, 164, 166) in order to produce a welded coil assembly. The metal blanks may be welded along the length of the inner sides of two sheet metal coils, or the metal blanks may be welded along the length of the outer sides of a single sheet metal coil, to cite a couple of possibilities. The welded coil assembly can then be fed through a progressive stamping apparatus (180) or other machine to create a complex metal part (188, 190, 198, 200).

Description

[0001] References to related applications [0002] This application claims the benefits of U.S. Provisional Application No. 61 / 079,717 filed on July 10, 2008. Technical field [0003] The present invention relates generally to metal forming processes, and more specifically to metal forming processes related to welded coil assemblies. Background technique [0004] So-called tailor welded blanks have been developed, in which thin metal parts are welded or otherwise attached to thick metal parts before the welded components are stamped, drawn or otherwise Ways to form finished parts. Although sometimes you can enjoy material and weight savings by using tailor-welded blanks, certain applications and processes may not be optimized by processing materials provided in blank form. Summary of the invention [0005] According to one aspect, a metal forming process is provided. The metal forming process may include the following steps: (a) generating a plurality of individual metal blanks; (...
