Increasing material manufacturing system mainly includes article carrying platform, more electric arc work compound modules, electric arc camera detection unit, forming dimension three-dimensional
The components such as measuring unit, stack shaping digital monitoring platform and negative-feedback monitoring unit below specifically solve it one by one
Release explanation.
The article carrying platform includes portal frame 12, workbench 6 and guide rail 7, wherein the main body of the portal frame 12 as system
Frame structure is equipped with 2 high-precision six-joint robots above.It can be along guide rail 7 relative to below article carrying platform
Workbench 6 execute Y direction namely perpendicular to the movement on the direction of paper, its crossbeam then can along Z-direction namely
The movement of upper and lower vertical direction (X-direction is then as shown, be left and right horizontal direction).In addition, on the crossbeam of the portal frame also
First six-joint robot 13 and the second six-joint robot 14 are installed；This two robot is moved in addition to that can complete six axis of itself
Outside, it can also control, move up and down on the gantry.
On the first six-joint robot 13, integral installation has more electric arc work compound moulds as one of key component
Block.The module via electric arc gun body clamping device 1 equipped with multiple mutually independent arc gums (being as shown in Figure 4 for example 5),
These arc gums respectively both can execute linear movement along X-axis, Y-axis and Z-direction, also can be performed using Z axis as rotation axis for example
The angle adjustment in [0 °, 60 °] range occurs, so that the relative position and operating attitude between them occur freely
Change.

Range, also further preferably each arc gum for example can be in relative to the angle of Z axis at this time (10 °, 30 °] interval range
When, it is now in part molten bath operating mode；In such a mode, arc heat is in the heat accumulation of deposit component between congruent melting pond
Between not congruent melting pond, cooling velocity of the deposit component from 800 DEG C to 300 DEG C also between congruent melting pond and not congruent melting pond it
Between；Further investigation revealed that being suitable for low-alloy steel under this operating mode, it is possible to form the metal component of martensitic structure
Electric arc increasing material manufacturing.
