Abstract

The invention discloses a composite gradual plate forming device and method, belonging to the technical field of plate processing. The device comprises a five-axis processing and forming unit, a plate clamping workbench, a hydraulic cylinder, a six-axis parallel robot-assisted processing platform and other components, wherein the five-axis processing and forming unit is arranged on the main body bed body of a machine tool; the plate clamping workbench is arranged on a machine tool workbench through the hydraulic cylinder; and the six-axis parallel robot-assisted processing platform is arranged below the plate clamping workbench and arranged on a machine tool workbench surface. By adopting the device, optional combination of forming tools can be realized on the five-axis processing and forming unit and the six-axis parallel robot-assisted processing platform, forming of a single forming head, forming of double forming heads and combined forming of a forming head and a supporting mold are completed, a plate and a mold can be cut at the early and later stages of forming, and composite forming of complex curved surface metal plates with various characteristics is realized. The device is a high-flexibility gradual plate forming device.

Description

technical field [0001] The invention relates to a device and method in the technical field of sheet material processing, in particular to a sheet material composite progressive forming device and a sheet material forming method thereof. Background technique [0002] Metal sheets are widely used in aviation, aerospace, automobile, shipbuilding and other manufacturing industries. The traditional sheet metal stamping forming method is suitable for mass production and processing, but for small batches, multi-variety and sample trial production processing, a new technology has emerged in recent years. A method for incremental forming of sheet metal. This method does not need to make a special stamping die for the product, has the characteristics of flexible processing methods, high forming limit, and low processing cost, and is especially suitable for the processing and production of small batches of metal sheets. [0003] After searching the existing incremental forming technol...
