Abstract

The invention discloses a rapid and flexible forming method and flexible tool for a large-curvature thin-wall plate with the irregular surface. The flexible tool comprises a supporting base, a fixed support, a movable support, two layers of supporting plates and a plurality of unit pressing rods, wherein the fixed support and the movable support are assembled on the supporting base; the two layers of supporting plates are installed on the fixed support and the movable support through fixing frames; each layer of supporting plates comprise two opposite I-shaped supporting plates and two opposite II-shaped supporting plates; the two opposite I-shaped supporting plates and the two opposite II-shaped supporting plates are used as edges to define a rectangular or square cavity; the unit pressing rods are provided with external threads; the I-shaped supporting plates and the II-shaped supporting plates are provided with through holes; and internal threads are formed in the through holes. The unit pressing rods are assembled on the I-shaped supporting plates and the II-shaped supporting plates through the external threads and the internal threads to form two sets of upper and lower movable unit pressing rod arrays which are opposite in a one-to-one mode, so that the clamping problem in rapid reshaping and remanufacturing of a complex large-curvature irregular curved plate is solved.

Description

technical field [0001] The invention belongs to the technical field of robot flexible forming, and in particular relates to a method for rapid flexible forming of thin-walled sheets with irregular and large curvature surfaces and flexible tooling. Background technique [0002] Flexible Forming Technology of Robot (FFTR) is an efficient formless flexible forming technology for sheet metal based on computer-aided modeling technology, computer-aided processing technology and the principle of metal plastic forming. The basic idea of ​​rapid prototyping is to separate the outer contour of the processing model along the vertical direction according to a certain layer spacing to separate a series of two-dimensional contour lines at each level, and use CAM (ComputerAided Manufacturing) software to generate each two-dimensional contour line The trajectory loading path, the forming tool head follows the generated loading path under the control of the robot, and performs continuous loa...
