The invention discloses a jacket type composite additive manufacturing device. The jacket type composite additive manufacturing device comprises a sealed forming cabin and a base arranged in the sealed forming cabin, wherein a jacket deposition forming device is arranged on one side of the base, a
casting forming device is arranged on the other side of the base, an extruding /
forging / rolling mechanical auxiliary device is arranged over the base, the
casting forming device is connected with a
metal smelting device through a flow guide
pipe, the
metal smelting device communicates with the flow guide
pipe through a flow control element, and when
metal liquid in a jacket is cooled to the proper pressure
machining temperature, the metal liquid in the jacket is subjected to combined
machining through the device. According to the jacket type composite additive manufacturing device, through the
casting forming device, conventional wire and
powder base metal is replaced with large-block
base metal, the sufficiency of metal
metallurgy is improved through the metal
smelting device, a deposited blank is subjected to three-way
extrusion stress, the action mode of an existing deposition and one-dimensional composite additive forming device is changed, the consistency and stability of a structure and performance of a formed component are greatly improved, the
manufacturing efficiency is greatly improved, and the manufacturing cost is reduced.
