Description
Technical field
The utility model belongs to high energy beam processing technique field, is specifically related to a kind of high energy beam and increases the equipment that material is manufactured large scale metallic element.The utility model is the increasing material manufacturing technology being synchronized with the movement based on high energy beam sweep generator and Powder spreader, and the high efficiency that is particularly useful for large-size and high performance, high accuracy and labyrinth metallic element is shaped.
Background technology
Increasing material manufacturing technology, claim again three-dimensional printing technology (3D-Printing), is a kind of emerging manufacturing technology.Be different from traditional waiting material manufacture (casting, forging, welding) and subtract material manufacture (machined), increase material manufacturing technology based on discrete-accumulation rule, according to the three-dimensional data of parts, pattern with layering stack links together material, until complete the shaping of whole part, the feature with high flexible, personalization is current manufacturing frontier development.According to the difference of raw material, the manufacture of increasing material can be divided into rapid prototyping manufacture (Rapid Prototyping-RP) and the near-net-shape (Rapid Manufacturing-RM) of the parts that can directly come into operation.It is raw material that RP technique be take the nonmetallic materials such as liquid resin, paraffin, paper and silk material, manufactures prototype exemplar and the model of non-densification, is usually used in design optimization, Product evaluation and publicity.By contrast, take metal dust or the silk material parts near-net-shape technology that can directly come into operation that is raw material, can directly complete the quick manufacture of various shaped pieces, load-carrying member, there is higher using value.
The process of near-net-shape has a variety of, different with the mode of material category and interpolation material according to adopted energy source (such as laser beam, electron beam, ion beam, electric arc etc.), can be subdivided into many types again.Current, in the 3D of metallic element printing-forming technique, with laser beam, electron beam (below both being generically and collectively referred to as to " high energy beam "), be shaped with fastest developing speed, also industrial quarters is accepted the most.According to the difference of raw metal supply mode, use maximum increasing material manufacturing technologies to comprise: the direct manufacturing technology of Laser Melting Deposition (the Laser Melting Deposition based on synchronous powder feeding system, hereinafter to be referred as LMD technology), electron beam fuse based on automatic feeding increases material manufacturing technology (Electron Beam Wire Melting, hereinafter to be referred as EBWM technology), the laser selective melting of laying based on powder bed increases material manufacturing technology (Selective Laser Melting, hereinafter to be referred as SLM technology) and electron beam selective melting increasing material manufacturing technology (Electron Beam Selective Melting, hereinafter to be referred as EBSM technology).
Laser beam or beam power that LMD and EBWM technology adopt are very high, spot diameter (or beam spot diameter) is large, and deposition efficiency is high, particularly adopts heavy duty machine tools as motion, therefore be applicable to shaping large scale hardware, but be difficult to realize the Precision Machining of complex component.
The mode that SLM and EBSM technology are laid based on powder bed, its process can be summarized as follows: first utilize paving powder system to lay one deck at substrate surface and have certain thickness powder, laser beam or electron beam carry out selective melting according to default track to powder bed subsequently, and cooling, solidify formation sedimentary deposit; By the substrate decline height identical with deposit thickness, again lay powder bed selective melting, until complete the shaping of whole parts.SLM and EBSM technology generally adopt laser instrument that power is lower or electron gun as energy source, and its focal beam spot or beam spot diameter are less, are generally 0.1～0.2mm.In process, high energy beam is only rapid scanning on the bisque of 0.02～0.2mm at thickness, forms small molten bath and solidifies rapidly, and heat accumulation is little, and parts precision and surface quality are high.Therefore, SLM and EBSM technology are particularly suitable for the manufacture of complicated shape metal parts.
Yet the maximum deficiency that SLM and EBSM technology exist is that its forming efficiency is low.Because the high energy beam power adopting is low, hot spot or beam spot diameter little, its forming efficiency is starkly lower than LMD and EBWM technology, is manufacturing large scale parts overlong time.Therefore the forming efficiency that, further improves SLM and EBSM technology becomes the task of top priority of this technology of development.
At present, existing some relating to, is improved the method for SLM/EBSM working (machining) efficiency and the patent of relevant device is open.Domestic patent documentation " for multiple laser scanning system and the method for laser fast forming process equipment " (publication number is CN 103358555A) discloses a kind of method and apparatus that can be used for improving SLM efficiency.This equipment utilization laser beam splitter, is divided into a branch of the first laser and a branch of the second laser by initial laser beam.Equipment comprises the first scanning element and the second scanning element, the first scanning element and the second scanning element under the control of control signal, adjust respectively the first laser and the second laser scans according to default track simultaneously, thereby improved to a certain extent SLM working (machining) efficiency.Yet owing to adopting the method for beam splitting, the power of the first laser and the second laser, lower than initial laser beam, for guaranteeing the abundant fusing of powder, certainly will will reduce lift height or reduce sweep speed, thereby greatly having limited the room for promotion of SLM working (machining) efficiency.
Domestic patent documentation " precinct laser fusion building mortion and the method for medical magnesium alloy metal part " (publication number: CN 101856724A) disclose equally a kind of SLM equipment.This equipment comprises control device, powder sending and laying device, laser transmission mechanism, gas cleaning plant and sealing working chamber, the paving that wherein powder sending and laying device comprises hopper and is installed on both sides, hopper below is whitewashed, the corresponding setting of feeding port above hopper top and working chamber, the below that paving is whitewashed is corresponding with the upper surface level of formation cylinder, in the hopper of powder sending and laying device, is provided with heater strip.Before metal dust is preset to formation cylinder substrate, utilize this heater strip by its preheating in advance, improve the absorptivity of metal dust to laser energy.Under same laser energy input condition, can obtain higher forming efficiency.But this equipment adopts " unidirectional paving powder " mode, preset one deck powder needs powder sending and laying device back and forth movement one week in working chamber, and the non-productive work time is too much, has hindered equally the remarkable lifting of SLM working (machining) efficiency.
Domestic patent documentation " a kind of electron beam selective melting manufacturing process of no-welding-seam metal beehive member " (publication number: CN 103273065A) disclose a kind of EBSM method, the equipment that the method adopts comprises electron beam fast forming machine and the computer joining with electron beam fast forming machine, wherein electron beam fast forming machine comprises lifting workbench, Chu Fenxiang, Powder spreader and electron beam generator, the slicing profile data that generate according to computer, thus electron beam successively scans and obtains metal beehive member metal dust bed.The involved storage powder case of the method is symmetrically arranged in the left and right sides of working chamber, thereby realizes " two-way powder laying ", has improved the efficiency of EBSM processing metal honeycomb structure.Yet in above-mentioned patent, this step of high energy beam scanning deposition must be treated can carry out after powder bed is laid, the stand-by period that paving powder operation causes is longer.
Except published Patents, the EOS company of Germany has released the SLM equipment of model for " EOS M 400 " in the recent period, and equipment adopts " two-way powder laying " structure, can realize the high efficiency manufacture of metallic element.Germany Fraunhofer laser technology Research Institute goes out the SLM equipment that a kind of spot diameter can regulate continuously.When shaping large scale parts, adopt the laser beam flying deposition part core of high power, large spot, adopt the laser beam flying deposition part shell of low-power, small light spot simultaneously, thereby on the basis that guarantees parts precision and surface quality, realized the lifting of forming efficiency.The Arcam company of Sweden develops the EBSM equipment that model is " Arcam Q-20 ", and equipment adopts " two-way powder laying " structure, can complete the processing of high-precision metal parts.
Yet the said equipment is in reality processing, it is independently in time that powder bed is laid with these two processes of high energy beam scanning deposition.Only have when powder is preset complete after, high energy beam just scans and forms sedimentary deposit according to default track to this layer of powder constituency.According to the difference of concrete paving powder mode (unidirectional paving powder or two-way powder laying), the time of the preset one deck powder of existing SLM/EBSM equipment is approximately 10～30s.When being shaped larger-size parts, Chang Gaoda is thousands of and even up to ten thousand for the deposition number of plies, because " stand-by period " that fore-put powder bed causes can seriously reduce the forming efficiency of SLM/EBSM up to tens hours, and limited can process component dimension limit." EOS M400 " is not only 400mmx400mmx400mm with the limit formed body integration of " Arcam Q-20 "
3with 350x380mm (Φ/H).
In sum, existing SLM/EBSM technology is not owing to can finely working in coordination with between paving powder craft process and high energy beam scanning forming process, and causing cannot be in the efficient shaping that truly realizes large scale, high-test metal parts.Therefore, inventing a kind of high energy beam that can produce efficiently large-size and high performance, high accuracy, labyrinth metallic element, to increase material manufacturing equipment significant.
