Description
Technical field
Coaxial compound multi-laser beam+electric heating silk material deposition method belongs to manufacturing field, specifically, relates generally to metal zero
A kind of DIRECT ENERGY deposition formation method that part increasing material manufacturing (3D printing), reparation remanufacture.
Background technique
Metal parts increasing material manufacturing and to remanufacture be the hot spot studied at present.Metal increases material manufacturing technology can be according to part
Three-dimensional CAD model, do not need mold, direct forming goes out metal parts.This techniques save die cost and manufacturing schedule,
It advantageously reduces product development cost, shorten the development cycle, rapidly adapt to market needs, and particularly suitable structure is complicated part
With the quick manufacture of mold, the unmanageable part of conventional method and single and mini-batch production part.It remanufactures with old machinery equipment
Or its components is blank, and using special technique and technology, primary new manufacture is carried out on the basis of original manufacture, and
Remanufacture the product either performance or quality come out and be all no less than original new product, and consume the energy, resource and
The pollutant of discharge is all fewer than manufacturing the process of new product.It is exactly the mistake for allowing old machinery equipment to shine vitality again
Journey is beneficial to energy conservation consumption reduction, reduces environmental pollution, significant to the development for pushing technological revolution and social economy.
Energy Direct precipitation is one of metal parts increasing material manufacturing and the main technique remanufactured, and it is heavy to occur laser at present
The various metals part increasing material manufacturing such as product, electron beam deposition, arc deposited and plasma deposition and remanufacture technique and its corresponding
Equipment；In addition, the melting of metal powder bed is also one of the main technique of metal increasing material manufacturing, but be not suitable for metal parts
It remanufactures.But there is also have many problems in application aspect for these techniques and equipment.
Currently, metal increasing material manufacturing and to remanufacture the outstanding problem showed in production be parts quality defect, cost mistake
Height, production efficiency are too low.It is not high as the consistency of the increasing material manufacturing of material or the metal parts remanufactured using powder, increased with silk material
The part consistency that material is manufactured or remanufactured is preferable.Often there is nodularization problem in metal powder bed smelting process, powdering movement by
To obstruction, forming technology cannot continue down；During powder-feeding laser deposits (cladding), usually because some technique is joined
Several fluctuations causes technical process that cannot continue, and workpiece is scrapped.Metal increasing material manufacturing, to remanufacture equipment price relatively high
It is expensive, for example, import metal powder bed fusion apparatus generally at 4,000,000 yuans or so, laser direct deposition equipment is also required to
2000000 yuan or so.Currently, laser price drops, whole equipment cost also accordingly declines, but still because of other important component prices
It is so more expensive, metal increasing material manufacturing and remanufacture equipment price or relatively high.It metal increasing material manufacturing and remanufactures used
Material, especially dusty material are more expensive, and increasing material manufacturing or the labour cost for remanufacturing investment are also high.In addition, current metal
It increasing material manufacturing and remanufactures that speed is very slow, and efficiency is extremely low, shapes a part sometimes and need tens day time.
Summary of the invention
In response to this, this patent analysis there is currently various metal increasing material manufacturing methods pros and cons basis
On, using the method learnt from other's strong points to offset one's weaknesses, and currently associated subject technology (such as laser technology) current situation is combined, has invented one kind
New DIRECT ENERGY deposition formation method, i.e., coaxial compound multiple laser+electric heating silk material deposition method, with improve deposition quality and
Efficiency reduces cost.
The invention patent solution to problem is: the multiple laser for being evenly distributed on the surrounding centered on silk material focuses
The coaxial recombination energy field of resistance thermosetting generated when being powered afterwards with silk material, heating fusing silk material, deposition formation metal component.Multi beam
Laser is imported from optical fiber, and " A myriad of stars surround the moon " formula is evenly distributed on using the center line of energization silk material as the rotational circle of axis after collimation
Convergence hot spot, convergence laser and the resistance that silk material generates when being powered are formed when reaching workpiece or substrate surface on the conical surface, after focusing
The coaxial recombination energy field of thermosetting.Converge light spot shape in addition to each Shu Jiguang self character, number of beams and optical delivery, standard
Straight and focusing parameter has the corner dimension for additionally depending on each beam laser center axis and workpiece or substrate surface product outside the Pass, thus
By adjusting the corner dimension between each beam laser center axis and workpiece or substrate surface, it can control multi beam and focus laser in work
Part or the light spot shape of substrate surface convergence, change the anisotropic character of deposition formation.In metal deposition process, molten bath,
The variation of silk material temperature, i.e. metal deposit state change, and resistance in circuit is caused to change, and cause the wave of heated current
Dynamic or even open circuit, and the fluctuation of electric current even open circuit is easy detection, so, this patent can electric current by detection stream through silk material
Signal monitors coaxial compound multiple laser+electric heating silk material deposition process state.
The beneficial effect of the invention patent is not only to have ensured the higher stock utilization of silk material and deposition efficiency, but also utilize more
Shu Jiguang with resistance heat is compound obtains high capacity usage ratio, also because available laser and its optical transmission component ten are divided into
Ripe, price is relatively inexpensive and the silk material price relatively inexpensive with respect to powder and reduces cost.
