【摘要】：纖維增強復合材料熔融沉積成型增材制造技術(FFP:FRP-FDM-3DP)是3D打印的前沿技術,可以有效提高FDM成型3D打印產(chǎn)品的強度和精度,增強產(chǎn)品的應用范圍。雖然FFP具有以上諸多優(yōu)勢,但是也存在一些關鍵問題,如:沒有專門針對FFP專用線材的生產(chǎn)擠出設備;粉末纖維增強效果有限,連續(xù)纖維增強材料拉絲現(xiàn)象嚴重、不易牽引和切斷、無法打印結(jié)構復雜的零部件以及鏤空件;工作效率低等問題。據(jù)此,本文在研究FFP關鍵裝備的基礎上,重點研究短切纖維增強復合材料熔融沉積成型增材制造裝備。主要研究內(nèi)容及結(jié)論如下:(1)研制微型低耗短纖維增強復合材料熔融沉積成型3D打印專用線材擠出設備。采用擠出成型原理結(jié)合3D打印專用線材擠出模具研制微型FFP專用線材擠出設備。用以制備不同種類、規(guī)格、含量的纖維及樹脂增強復合材料熔融沉積成型3D打印專用線材。(2)研制多頭高效FDM成型3D打印設備。為提高3D打印工作效率,提出3D打印技術的低成本、多頭高效打印的生產(chǎn)模式。依據(jù)熔融沉積成型原理設計了多打印頭3D打印機,并與單打印頭3D打印機進行對比實驗,結(jié)果表明據(jù)此設計的多頭3D打印機,能夠3-5倍提高工作效率和設備利用率,快速完成產(chǎn)品的打印生產(chǎn)工作。(3)結(jié)合案例介紹短纖維增強復合材料熔融沉積成型3D打印技術的應用情況。以團隊研制的第五套人民幣硬幣分揀機為案例簡要介紹短纖維增強復合材料熔融沉積成型3D打印技術的應用情況。
[Abstract]:Fiber reinforced polymer (FFP:FRP-FDM-3DP) is the leading technology of 3D printing. It can effectively improve the intensity and accuracy of FDM forming 3D printing products, and enhance the application scope of products. Although FFP has many advantages, but there are some key problems, such as: no specific FFP special wire extrusion equipment; powder reinforced effect is limited, continuous fiber reinforced material drawing phenomenon, not easy to traction and cutting, unable to print complex parts and hollow parts; the problem of low work efficiency. On the basis of the study of the key equipment of FFP, this paper focuses on the research of the equipment for the manufacturing of short cut fiber reinforced composites by molten deposition and deposition. The main contents and conclusions are as follows: (1) the development of 3D printing special wire extrusion equipment for micro low consumption short fiber reinforced composites by melting deposition molding. The extrusion molding principle combined with 3D printing special wire extrusion die was used to develop the micro FFP special wire extrusion equipment. It is used to prepare 3D printing special wire for fiber and resin reinforced composites with different kinds, specifications and content. (2) the development of multi head high efficiency FDM 3D printing equipment. In order to improve the efficiency of 3D printing work, the production mode of low cost and multi head high efficiency printing with 3D printing technology is put forward. According to the principle of fused deposition modeling design of multiple print head 3D printer, and is compared with a single print head 3D printer, long 3D printer results of this design can complete, 3-5 times to improve work efficiency and equipment utilization rate of finished products, print production work quickly. (3) the application of 3D printing technology for melt deposition of short fiber reinforced composites is introduced in the case of a case. In this paper, fifth sets of RMB coin sorting machines developed by the team are used as a case to introduce the application of 3D printing technology for short fiber reinforced composites.
