Description
Technical field
The present invention relates to increases material manufacturing technology field, specifically a kind of laminated construction solid phase increasing material manufacturing method.
Background technique
The design and manufacturing philosophy of increasing material manufacturing are increasingly to the trend development that light-weight, the service life is high, at low cost.Traditional
Components are manufactured, depend on traditional casting, forging, welding method complete, existing increasing material manufacturing mainly with
Based on the built-up welding for melting silk material or powder material, and solid phase increases material based on use strip, and single track " wall " body cannot achieve based on stacking
The integrated increasing material manufacturing of block and more complex component.
Existing fusing increases material manufacturing technology relies primarily on heat source fusing metal and directly manufactures, and product tissue generally is
As cast condition column crystal or dendrite and equiax crystal line and staff control, are presented apparent directionality and anisotropy.It is said from grain size, these
Problem is by shortage crystal grain refinement link, and without constraining freely micro- casting deposition forming institute Gu Te under the conditions of mobile heat and mass
Some thermodynamics, dynamics, geometry feature are determined.
The fusing increases material manufacturing technology carried out at present for metal material, not only the cost is relatively high, forming efficiency and property
Can aspect also it is difficult to ensure that, a large amount of low melting point element scaling loss especially in fusion process, need be directed to service performance to metal
Silk material or strip carry out secondary fusion, wherein the not foot point of micro- casting and welding increases in material in fusing and constantly accumulated, wherein depositing
The difference in product (plate, silk material, bar) performance is being manufactured with traditional industry, technique not only increases process,
And it increases manufacturing cost, while the product that the short slab in performance manufactures it is difficult to keep up with the need of modern industry progress
It asks.
And it is substantially to use strip and utilize moulding forming/diffusion connection method layer-by-layer that solid phase, which increases the method that material uses,
What the method for superposition was achieved, first, how to eliminate, the overlap joint that improves between two strips is the key that forming, forming
It is easy to the problem of penetrability hole, folding etc. can not be made up by forming continuous processing mode therefore forming process occur in the process
Middle forming mode, path processing, overlapping mode are extremely crucial.
Second, strip cost is high compared with silk material, this is also the main restricting factor for limiting its popularization and application.
Summary of the invention
The object of the invention is to solve the problems, such as the above technology, break through the increasing of existing fusing both at home and abroad material directly at
The formability of shape high-performance aerospace components technology is difficult to control and the insufficient practical bottleneck of performance reliability, and thus

The present invention inherits the advantage that solid phase increases material, while also having optimization solid phase to increase material process, can also eliminate, improve two
Overlap joint between strip is that forming is easy to the problem of penetrability hole occur, and the invention is changed to by improving forming mode
Shape folding method and device break through solid phase forming overlapped key technology, be it is a kind of without phase-change, stablize overlap joint, extruding/forging
The accurate and inexpensive solid phase increasing material manufacturing process of formula, dense structure, forming.Technical solution of the present invention can be in large and medium-sized aviation knot
It is widely applied in the short route of component, high-quality, efficient, entirety manufacture, breaks through existing fusing both at home and abroad and increase the high property of material direct forming
The formability of energy aerospace components technology is difficult to control and the insufficient practical bottleneck of performance reliability, is such big-and-middle
Practical new way is opened up in the high-quality and efficient direct whole manufacture of type, high-performance complex parts, for high performance turbine boat of new generation
Quickly exploitation provides technological reserve for it.
