Description

一种送浆式金属部件増材制造方法及装置 One kind of paste type metal member manufacturing method and apparatus zo sheet feeding

技术领域 FIELD

[0001] 本发明属于增材制造技术领域,涉及一种金属部件增材制造方法及装置,更具体地说,涉及一种送浆式金属部件的增材制造方法及装置。 [0001] The present invention belongs to the additive manufacturing technical field relates to a method of manufacturing a sheet metal part and by apparatus and, more particularly, relates to additive manufacturing method and apparatus for metal slurry feed member. 背景技术 Background technique

[0002] 增材制造技术是近年来材料科学、机械科学、信息科学等多学科交叉而快速发展起来的一项新兴制造技术,具有低成本、高性能、短周期、不受部件几何形状影响、无需模具等特点,被誉为有望产生“第三次工业革命”的代表性技术,是大批量制造模式向个性化制造模式发展的引领技术。 [0002] The additive manufacturing technology in recent years, multidisciplinary materials science, mechanical, information science, etc. intersect a new manufacturing technology has developed rapidly, with low-cost, high-performance, short cycle, not the effect of geometrical shape member, no need to mold and other characteristics, known as expected to have a "third industrial revolution" representation technology, high-volume manufacturing model to personalized manufacturing model to lead the development of technology. 对于金属增材制造,目前的主要方法是依据CAD数据,利用热源(如激光、等离子弧、电子束等)加热金属材料,使其熔化再凝固,通过逐层累加材料熔层制造实体零件,材料由点、线、面、体顺序累积成型,实现自下而上构件制造。 For the metal additive manufacturing, it is currently the main method is based on the CAD data, using a heat source (e.g., laser, plasma arc, electron beam, etc.) heating the metal material, melted and then solidified layer by layer manufacturing entity accumulating part fusible material layer, material by points, lines, surfaces, sequential accumulation molded body, to achieve bottom to top member manufactured.

[0003] 而金属构件增材制造采用的同步添加材料主要有两种:粉末和丝材。 [0003] and the metal member using additive manufacturing synchronization There are two main additive: powder and wire. 其中,粉末材料加工成本相对较低,受材料性能影响较小;同时,易于熔化,对热源能量密度要求低,熔池形态易于控制,加工过程稳定,但采用粉末进行填充时有如下缺点: Wherein the powder material is relatively low processing costs, less impact by material properties; also, easily melted, the low energy density of the heat requirement, pool geometry easy to control, process stability, but with the following disadvantages by powder filling:

[0004] (1)粉末在输运过程中以及同热源交互作用的烧损过程容易导致粉末利用率低, 仅为20 %-30 %。 [0004] (1) the powder during transport and interaction with the burning heat source powder easily lead to low utilization of the process, only 20% -30%.

[0005] (2)存在粉尘污染,对环境及工人身体健康造成危害。 [0005] (2) the presence of dust pollution, damage to the environment and workers' health.

[0006] (3)送粉过程对粉末的外形和粒度要求较高,只有具有接近圆形粒度始终的粉末才能获得较为稳定的送粉过程,当采用纳米材料时由于材料本身较高的团聚和吸附性能, 粉末常常会吸附在管壁上造成送粉过程的失败。 [0006] (3) the shape of the powder feeding process and the powder particle size required higher only nearly circular having a particle size of the powder in order to obtain always stable powder-feeding process, when using nanomaterials material itself and higher agglomeration adsorption properties, the powder will often result in failure of the adsorption process on a powder feed tube wall.

[0007] ⑷送粉量调节响应效果差,从送分量调整到喷嘴出粉需要一定响应时间。 [0007] ⑷ powder feed amount adjusting poor response, adjust the sending component to the nozzle from the powder needs a certain response time.

[0008] 相比较于粉末材料,采用丝材时,材料利用率高,可达90%以上,而且送丝调节响应快,无粉尘污染,但其同样存在有如下缺点: [0008] Compared to the powder material, when using wire, material utilization, up to 90%, and the wire feed adjusting fast response, no dust pollution, but there are also the following disadvantages:

[0009] (1)采用丝材需要较高成本的丝材制造设备进行丝材拉拔。 [0009] (1) The wire requires a high cost wire drawing wire manufacturing equipment.

[0010] (2)塑性较差的金属合金难以制造成丝材。 [0010] (2) a metal alloy is difficult to fabricate into a poor plastic wire.

[0011] (3)丝材添加时对位置适应性差,一般仅适用于水平位置。 When adding a poor adaptability to the position of [0011] (3) wire, generally only in a horizontal position.

[0012] (4)丝材金属难于熔化,需要较高能量密度热源,且热源与送丝的协调性要求严格,易出现粘丝、顶丝等问题。 [0012] (4) difficult to melt a metal wire, a higher energy density heat source, and the source wire feed coordination demanding wire prone to stick, the top wire and so on.

[0013] 综上可见,常用的送粉式和送丝式金属增材制造技术各有优缺点,但共同的是都无法较好地适应实际生产要求。 [0013] Fully visible, conventional powder feeding metal wire and additive manufacturing techniques have advantages and disadvantages, but are not common is better adapted to the actual production requirements. 而将金属粉末与粘结剂及有机溶剂调制为浆状材料,作为金属增材制造的添加材料,则可克服粉末与丝材的缺点,同时又可综合两者的优点,具有材料利用率高、材料制作成本相对较低、无粉尘污染、送料过程稳定可控且调节响应快等特点。 And the metal powder with a binder and an organic solvent as a slurry modulation material, a metal material produced by adding material, can overcome the disadvantages of powder wire, while at the same advantages of both integrated, have a high material utilization , relatively low cost materials, no dust pollution, stable and controllable feeding process and adjusting quick response characteristics. 目前浆状材料主要用于金属粉末注射成形技术,但该技术是首先将料浆注入模具成形, 然后对成形后的材料进行脱脂、烧结来制造金属部件;其对注浆设备要求较高,且部件成形仍需借助模具。 The slurry materials are mainly used at present metal powder injection molding technique, but the technology is first injected into a mold forming a slurry, and then the material after molding was degreased and sintered to manufacture a metal member; the higher its grouting equipment requirements, and still by shaping the mold member. 而将浆状材料应用于三维金属部件增材制造的研究尚未开展,也未见提出或进行相似工作的相关报道。 The slurry material is applied to the study of a three-dimensional sheet metal part produced by not started, and no reports proposed or similar work. 发明内容 SUMMARY
