Abstract
The invention provides a die-free sheet metal forming process and a die-free sheet metal forming system.The die-free sheet metal forming process is used for machining sheet metal parts of an automobile sample, and the die-free sheet metal forming process comprises the following steps that S1, formability analysis and design are conducted on the sheet metal parts; s2, a mold and a forming blank holder are manufactured according to the result of formability analysis, and the peripheral shape for sheet metal forming of the sheet metal part is designed; s3, developing a process processing path of the plate, matching a die-free forming device and a processing positioning coordinate system of the plate, and counting a compensation value of the thickness of the plate; s4, the plate is machined through die-free forming equipment; and S5, cutting pre-positioning and cutting are conducted on the plate machined in the step S4.
Description
technical field [0001] The invention relates to a dieless sheet metal forming process and a dieless sheet metal forming system, in particular to a dieless sheet metal forming process used for the processing of automobile prototype car parts. Background technique [0002] At present, some parts of automobiles, such as floor panels, are high-precision thin-walled parts with complex parts characteristics, which are difficult to form and the dimensional accuracy will affect the dimensional chain of the entire vehicle. At present, in the auto parts manufacturing industry, steel or zinc-aluminum alloy molds are generally used for stamping and forming when manufacturing such parts. The process of manufacturing such parts includes digital and analog design, forming analysis, mold design, mold processing, mold trial and mold repair, part forming, laser cutting, manual shaping and other links. [0003] The dieless sheet metal forming technology is suitable for the processing of small...
