【摘要】：下料往往影響著生產(chǎn)線效率和后續(xù)工序的質(zhì)量。與傳統(tǒng)下料方法相比，應(yīng)力斷料法有低能耗、高效率、節(jié)約原材料、減少刀具損耗等優(yōu)點。本文設(shè)計了一種針對塑性材料的折斷機構(gòu)。 本文以應(yīng)力斷料法和裂紋技術(shù)為基礎(chǔ)，利用虛擬樣機技術(shù)，探討了塑性材料折斷機構(gòu)的工作原理，完成機構(gòu)的初步設(shè)計，在此基礎(chǔ)上進行虛擬建模和裝配。最后對其進行了運動學(xué)和動力學(xué)分析。在本文中主要做了以下工作： 1.分析了傳統(tǒng)下料方式存在的問題，論述了虛擬開發(fā)技術(shù)的優(yōu)勢，在此基礎(chǔ)上，探討了塑性材料折斷機構(gòu)的的工作原理，介紹其斷裂判據(jù)，建立疲勞壽命的估算模型。 2.應(yīng)用傳統(tǒng)設(shè)計方法，對塑性材料折斷機構(gòu)中的主要機構(gòu)-切槽機構(gòu)和預(yù)荷機構(gòu)進行結(jié)構(gòu)設(shè)計，完成其裝配圖；分析出機構(gòu)的薄弱環(huán)節(jié)，在后續(xù)部分對其進行運動學(xué)和動力學(xué)分析。 3.應(yīng)用Pro/E軟件對切槽機構(gòu)和預(yù)荷機構(gòu)進行虛擬虛擬建模和裝配,對其進行干涉分析，修改并完善尺寸缺陷。 4.應(yīng)用ADAMS軟件對機構(gòu)進行運動學(xué)分析，得出的結(jié)論驗證了機構(gòu)運動原理的合理性；以刀具運動平穩(wěn)為目標，以斜面傾角為變量，對機構(gòu)進行優(yōu)化。 5.應(yīng)用有限元分析方法，，使用ANSYS軟件對主軸進行靜力學(xué)分析，結(jié)論驗證了強度和剛度符合要求；使用ANSYS對主軸進行模態(tài)分析，找出所存在的問題，為優(yōu)化設(shè)計提供依據(jù)。
[Abstract]:Cutting often affects the production line efficiency and the quality of subsequent processes. Compared with the traditional cutting method, the stress cutting method has the advantages of low energy consumption, high efficiency, saving raw materials and reducing tool loss. In this paper, a fracture mechanism for plastic materials is designed. Based on stress cutting method and crack technology, this paper discusses the working principle of plastic material fracture mechanism and completes the preliminary design of the mechanism by using virtual prototyping technology. On this basis, virtual modeling and assembly are carried out. Finally, kinematics and dynamics are analyzed. In this paper, the following work has been done: 1. This paper analyzes the problems existing in the traditional blanking method and discusses the advantages of the virtual development technology. On this basis, the working principle of the plastic material fracture mechanism is discussed, the fracture criterion is introduced, and the fatigue life estimation model is established. 2. By using the traditional design method, the structural design of the main mechanism in the plastic material fracture mechanism, the slot cutting mechanism and the preloading mechanism, is carried out, the assembly drawing is completed, and the weak links of the mechanism are analyzed. In the following part, kinematics and dynamics are analyzed. 3. Virtual modeling and assembly of slot cutting mechanism and preload mechanism were carried out by using Pro/E software. The interference analysis was carried out to modify and perfect the dimension defect. 4. The kinematics analysis of the mechanism is carried out by using ADAMS software, and the conclusion verifies the reasonableness of the mechanism's motion principle, and the mechanism is optimized by taking the tool motion stationary as the target and the inclined angle as the variable. 5. The static analysis of the spindle is carried out by using the finite element analysis method and the ANSYS software. The conclusion is that the strength and stiffness meet the requirements, and the modal analysis of the spindle is carried out by using ANSYS to find out the existing problems, which provides the basis for the optimization design.
