Abstract

The invention relates to a device and a method for clamping a flexible curved surface of a metal plate in an incremental forming process. The device comprises a rigid base and a plurality of clamping units which are distributed on the rigid base and have modularized structures, each clamping unit comprises a height adjusting assembly used for achieving vertical height adjustment of the clamping unit. The hinge assembly is connected to the height adjusting assembly; the lower clamping head is installed on the hinge assembly, and space posture adjustment of the lower clamping head and the upper clamping head can be achieved through the hinge assembly; by independently adjusting the height of each clamping unit and the angle of the clamping head, a flexible supporting surface adaptive to the curved surface morphology of a target workpiece can be constructed, and the flexible supporting surface is used for fixedly clamping a metal plate. Compared with the prior art, the method has the advantages that the forming quality and the material utilization rate are improved, the machining efficiency and the track precision are improved, the flexibility and universality are high, and the production cost is reduced.
