Abstract

Disclosed is a complicated thin-walled workpiece formation system and method based on progressive formation and additive manufacturing. The system comprises a progressive forming system, a laser metal deposition system and a control system. The progressive forming system comprises a worktable, a three-dimensional movement platform and an electric spindle, wherein the electric spindle is mounted on the three-dimensional movement platform and provided with a tool bit, and the worktable is arranged below the electric spindle and provided with a clamp. The laser metal deposition system comprises a fiber laser, a laser head, a powder feeder and a nozzle. The formation method is to clamp the plate to the fixture of the worktable, the control system controls the electric spindle to drive the tool bit to form the sheet layer by layer and to form the thin-walled shell; and then through laser, metal powder is fused and deposited on the thin-walled shell, and the block-type characteristics are formed. The complicated thin-walled workpiece formation system can realize the small batch and efficient manufacture of the complicated thin-walled workpiece, and has the advantages of saving material, and eliminating the need of mold and the like, and the manufacturing cycle of the complicated thin-walled workpiece is shortened.

Description

technical field [0001] The invention relates to a compound forming system and method for progressive forming and additive manufacturing of complex thin-walled parts having both thin-wall shell and block features, and belongs to the technical field of compound processing. Background technique [0002] Metal thin-walled components are key structural components and important functional components for lightweight mechanical equipment, and are widely used in transportation (automobiles, rail vehicles, ships), aerospace, machine tools, medical and energy equipment and other fields. With the rapid development of the high-tech industry, higher requirements are put forward for the delivery time and product quality of high-performance, lightweight, variable-batch and complex-shaped thin-walled components, which challenges the existing forming technology. It is urgent to vigorously develop and research new composite digital manufacturing technology, which is an effective way to improve...
