System and manufacturing method.
Background technique
Increasing material manufacturing is a kind of advanced machining manufacture of modern concepts, is a kind of near-net-shape technology, and current grinds
Study carefully and increases material with electric arc using laser gain material is focused primarily upon.The characteristics of laser gain material is that size of formed part control is accurate, but lacks
Point is that forming speed is slower, is not suitable for processing medium-and-large-sized component, and equipment cost is higher.It is with electric arc for heat that electric arc, which increases material,
Source carries out layer-by-layer heap according to planning path and covers, and equipment is simple, and it is a kind of metal increasing material manufacturing side of low cost that heap, which covers high-efficient,
Method is more suitable for the processing and manufacturing of large-scale component, but forming accuracy difference is its main drawback.
According to above, electric arc increasing material manufacturing is actually a kind of method of layer-by-layer built-up welding, and later layer is all in preceding layer
On the basis of carry out, and do not supported before first layer, it is therefore necessary to have the presence of substrate, first layer must rely on baseplate material
Heap covers.
During increasing material, the outstanding problem that substrate most easily occurs is exactly welding deformation.Workpiece inevitably generates change when welding
Shape, and electric arc increases material actually layer-by-layer built-up welding, every layer heap, which covers metal, can generate different degrees of deformation, these deformation are gradually accumulated
Superposition, it will cause the deformation that substrate is bigger.Often occur during test frock clamp after the completion of workpiece heap covers be difficult to dismantle,
Even there is the problem of tooling fractures because of deformation.Moreover, substrate deformation will lead to the original path Inefficiency in planning that heap covers, forming
Part and model deviate seriously, and manufacture is caused to fail；If consideration removes excess metal by way of mechanically cutting, can continue
At forming process, and more accumulation a part on the basis of former drip molding, however, this is necessarily required to be adjusted in real time according to deformation size
Post forming path, is significantly increased workload, it is also difficult to realize automation.In general, how control base board deformation is electric arc
Technical problem urgently to be resolved during increasing material manufacturing.
During electric arc increases material, drip molding can also be deformed due to uneven heating.In order to control the deformation of drip molding,
It avoids heap from covering tissue simultaneously to become thick due to multiple thermal cycle, Normal practice is between road and certain cooling is added in interlayer
Time, temperature is roughly equal between controlling the road heap coating Jian He, but it reduce forming efficiencies.
The welding process of TIG weldering is stablized, and joint quality is excellent, is suitable for almost the welding of all metals, increases for electric arc
Material manufacture can obtain the higher high-quality drip molding of precision.However, when TIG is welded in for increasing material manufacturing, due to welding gun and welding wire
Split-type design 55-75 ° of angle need to be generally kept between welding gun and welding wire in order to smoothly be sent into welding wire, this is serious to hinder
Accessibility of the welding gun in labyrinth forming, limits the flexibility and adaptability of automatic TIG welding.In addition, using fixture
Fixed welding wire is often inevitable on welding gun, fixture is due to wire feed rate and current parameters mismatch in the welding process the problems such as
Appearance deviate or rotate, and then influence the accuracy and reliability of wire feed, welding quality caused to decline.
