Abstract

The invention belongs to the technical field of plastic forming and welding, in particular to a device and method for forming and manufacturing a titanium alloy large-scale sheet-welding hatch cover. The present invention utilizes the manufacturing method combining resistance spot welding, electron beam penetration welding and electron beam butt welding to realize the forming and manufacturing of a large and complex sheet welding hatch cover composed of machined parts and sheet metal parts. Structural strength while achieving the greatest degree of lightweight design. After welding, the weld seam is well formed, and the surface has no defects such as cracks, pores and undercuts, which can meet the design requirements and use requirements. The pass rate and production efficiency of the product are high, and mass production can be realized.

Description

technical field [0001] The invention belongs to the technical field of plastic forming and welding, in particular to a device and method for forming and manufacturing a titanium alloy large-scale sheet-welding hatch cover. Background technique [0002] With the rapid increase of missile flight speed, the demand for lightweight heat-resistant load-bearing structures is increasing, and the application is becoming more and more extensive. Traditional hatch covers are generally single-curvature sheet metal parts or casting machine-added parts, which cannot meet the requirements of new missiles for lightweight structural design of complex hatch covers and as main load-bearing components. In addition, there are currently some multi-layer structure superplastic diffusion-connected flap parts. The overall manufacturing process of this type of parts is complicated, the manufacturing cost is high, there are many influencing factors, the production efficiency is low, and the product qu...
