Description
Technical field
The invention belongs to the part method for fast mfg.
Background technology
The direct metal part is made the international forward position that (Direct Rapid Metal Manufacturing) become the RP technical research fast, has occurred the multiple method of directly making metal parts fast at present.Wherein, can obtain the high method of density mainly contain powerful laser near-net forming technology (LaserEngineering Net-Shaping, LENS), electron beam deposition technology, plasma deposition method etc.See H.Muller, J.Sladojevic.Rapid tooling approaches for small lotproduction of sheet-metal parts, Journal of Material ProcessingTechnology, 2001,115:97-103; Wang Huaming. metal material laser surface modification and high-performance metal part laser fast forming Research progress. aviation journal, 2002,23 (5): 473-478.The LENS method is to adopt high power laser successively will deliver to fusion of metal powder on the substrate, and rapid solidification finally forms workpiece, and the density of workpiece is higher than the selective laser sintering method.But problems such as there is not high, the inaccessible full density of forming efficiency in this technology, equipment investment is big, surface accuracy is not high.The electron beam deposition method adopts powerful electron-beam melting dusty material, applies electromagnetic field according to computer model, and the motion of control electron beam successively scans until the whole part shaping and finishes.Yet its process conditions are strict, need carry out in a vacuum, cause forming dimension to be restricted, the equipment manufacturing cost costliness.The metal dust that the beam-plasma fusing that it is good that the plasma deposition method is employing high compression, convergence is supplied with synchronously, on substrate, successively pile up the technology that forms metal parts or mould, have than LENS method and electron beam deposition method forming efficiency height, be easy to obtain full density, characteristics such as equipment cost is low are seen Bai Peigang, Shi Yuhong, Cheng Jun etc. three-dimensionally shaped welding Rapid Manufacturing Technology, solder technology, 1998 (6): 39-40.But the forming accuracy of this technology is not high, when the high part of deposition forming required precision, is to improve precision to adopt micro arc plasma, but its energy shortage, and needs to improve the stability and the convergence of arc column.
Summary of the invention
The invention provides the direct manufacture method of no mould of a kind of part and mould, in forming process with beam-plasma and low-power laser Shu Fuhe, both can bring into play plasma arc deposition forming efficient height, easily obtain full density, advantage that cost is low, can bring into play the higher strong point of the better laser forming precision of convergence again.
The direct manufacture method of no mould of a kind of part of the present invention and mould comprises the steps: (1) requirement according to part forming, the three-dimensional CAD model of design elements; (2), three-dimensional CAD model is carried out slicing treatment according to part shape and dimension precision requirement; (3) carry out path planning according to the characteristics of individual-layer data and every layer of shape, generate the every layer of required numerical control code that is shaped; (4) adopt the plasma deposition spray gun of numerical control, with the silk material or the powder of alloy, intermetallic compound, cermet or pottery, on substrate according to every layer numerical control code deposition forming; (5) in the deposition forming process, that plasma arc and laser beam is compound, make laser beam focus on the zone of beam-plasma effect; (6) according to above-mentioned steps (3)～(5) deposition forming successively, reach the requirement of accessory size shape until formed body.
The direct manufacture method of no mould of described part and mould, can be in forming process or after the shaping end, with ultrasonic wave, dry type spark machined, milling or laser ablation formula method, formula fine finishining is removed on the formed body surface, or carry out surface treatment with laser and plasma, to reach required surface quality.
The compound laser beam of the direct manufacture method of no mould of described part and mould and plasma arc can be CO
2The laser beam that laser instrument, YAG solid state laser or Q-switched laser send, CO
2The mean power of laser instrument, YAG solid state laser or Q-switched laser is in the 1000w.
The present invention is mutually compound with laser beam with beam-plasma in forming process, promptly make laser beam focus on the zone of beam-plasma effect in the coaxial of beam-plasma or a side, materials such as metal that will be higher than material melting point such as existing paper, photosensitive resins, intermetallic compound successively are melted on the substrate.The present invention is that the plasma deposition method of feature is melted on the matrix stack shaping successively with a shaping powder or a silk material apace with high efficiency, densification, low cost; Compound low-power laser bundle in forming process, for deposition forming increases shaping heat energy,, in plasma arc, add laser the magnetic compression effect of plasma arc is strengthened to obtain fine and close and the good formed body of structure property, arc column is compressed, and forming accuracy improves.In forming process or after the end that is shaped, according to the requirement of product surface quality and the surface condition of accumulation horizon, sometimes need the fine finishining of surface removal formula to be carried out on the formed body surface with ultrasonic wave, dry type spark machined, milling or laser, or carry out surface treatment with laser and plasma, to reach required surface quality.
The present invention keeps plasma deposition shaping cost low, forming efficiency height, formed body are easy to reach the advantage of full density, and generally are shaped under the atmospheric environment condition, and only additional low-power laser bundle when being shaped, equipment and operating cost are lower than laser cladding and electron beam forming technique.Therefore, adopt the present invention can obtain the part or the mould of the good high-melting-point materials such as metal of organization mechanics performance and surface quality fast, at low cost.
