The laser-assisted shearing spinning device comprises a spinning assembly and a laser adjusting assembly, whereinthe laser adjusting assembly comprises a laser device, the laser device is mounted on the spinning assembly through an adjustable connecting assembly, the laser device is used for irradiating a workpiece to be machined, the irradiation position of the laser device on the workpiece to be machined can be corrected through the adjustable connecting assembly, and the spinning assembly is used for spinning the workpiece to be machined. According to the laser-assisted shearing spinning device, the structural design is refined, a laser heat source is accurately input, spinning machining of a small half-cone-angle cylinder can be achieved with a multi-pass or one-pass technology, and the problem of difficulty in forming of the metallic small half-cone-angle thin-walled cylinder which is difficultto deform is solved; and compared with the prior art that only the laser heating circumferential position of the plate is determined, through combination of radial and circumferential positioning with accurate regulation and control of the heating position of the plate, simultaneous heating of a stretch bending area and a shearing area can be achieved, a laser heat source can be accurately loadedto the whole deformation area, and a better forming machining effect is achieved.

Description

technical field [0001] The invention relates to the technical field of metal plate spinning forming, in particular to a laser-assisted shearing spinning device and a forming method. Background technique [0002] Lightweight alloy conical thin-walled components are a typical product widely used in aerospace vehicles. Currently, multi-pass shearing and spinning processes are used to complete the integral forming of such high-precision equal-wall-thickness thin-walled components. Due to the severe work hardening of materials caused by multi-pass cold shear spinning, the hard-to-deform light alloy materials will crack, resulting in processing failure, and the interspersed annealing process will bring long process chains, poor geometric accuracy of parts, and microstructure. Difficult to control etc. [0003] Shear spinning is to apply a force load to a certain point on the sheet through the rotary wheel, and the sheet has a strong plastic flow in a small local area, and the thi...

Problems solved by technology

However, there are obvious deficiencies in the existing laser spinning process: the laser heat source does not irradiate the maximum tensile deformation zone, and there is a lack of precise position control parameters
