A method and device for hot rolling and rolling of arc wire-feeding additive inclined roller combined wheel

Abstract

A manufacturing method and device for hot rolling of an arc-feeding wire-feeding additive oblique-roller combination wheel. The invention relates to the technical field of 3D printing. A skewed roller for arc wire-feeding additive manufacturing with compact structure, high processing efficiency and good processing effect is proposed, which can refine grains, increase density, reduce internal defects, and finally improve the mechanical properties of arc additive manufacturing formed parts. Combination wheel hot rolling manufacturing method and device. The technical solution of the present invention is: manufacture according to the following steps; 1), initialization; 2), arc wire feeding additive; 3), rolling processing; 3.1), inclined roller strong shear deformation; 3.2), preliminary flattening; 3.3), complete flattening; 4), cooling; 5), waste edge removal; complete. It can refine the grains, increase the density and reduce internal defects of the formed parts by arc wire feeding additive manufacturing, so as to finally improve the mechanical properties of the parts.

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
