Arc wire feeding additive oblique roller combined wheel hot rolling manufacturing method and device

Abstract

The invention discloses an arc wire feeding additive oblique roller combined wheel hot rolling manufacturing method and device, and relates to the technical field of 3D printing. The wire feeding additive oblique roller combined wheel hot rolling manufacturing method and device are exquisite in structure, high in processing efficiency and good in processing effect, and can refine crystal grains ofan arc additive manufacturing formed part, improve compactness and reduce internal defects, thereby finally improving mechanical properties. The technical scheme of the invention is as follows: the manufacturing method comprises the following steps: (1) initialization; (2) arc wire feeding and material adding; (3) rolling; (3.1) strong shear deformation of an oblique roller; (3.2) primary flattening; (3.3) full flattening; (4) cooling; and (5) cutting of waste edges. The crystal grains of the arc wire feeding additive manufacturing formed part can be refined, the compactness is improved, internal defects are reduced, and the mechanical properties of the part are finally improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to the improvement proposed for the refinement of the crystal grains, the improvement of the density, and the reduction of internal defects of formed parts produced by arc additive manufacturing. Background technique [0002] At present, cutting-edge manufacturing fields such as aviation, aerospace, and shipbuilding are developing towards large-scale and integrated equipment. The size of key components is increasing, the structure is becoming more and more complex, and the performance requirements are increasing. Using traditional manufacturing technologies such as casting, forging, and machining to produce large, integral, high-performance alloy components requires not only heavy casting, forging, and machining equipment and large molds, which is technically difficult, but also has a large amount of material cutting and low material utilization. The cycle is long and the cost i...

Problems solved by technology

However, this patent only considers the temperature of the material roll, and does not consider the cooling of the material after the roll

In fact, the temperature of the deposited layer is very high after arc material addition, and then heating the substrate may not only lead to poor forming accuracy of the material, but also cause coarse grains in the hot stacking area, and the patent uses straight rolls, and the deformation in the hot rolling area is insufficient
