【摘要】:隨著國(guó)家對(duì)新型墻材產(chǎn)業(yè)的鼓勵(lì)支持,液壓磚機(jī)正向大型化、高精度和自動(dòng)化方向發(fā)展。針對(duì)大型液壓磚機(jī)對(duì)于結(jié)構(gòu)輕量化的要求,本文采用現(xiàn)代設(shè)計(jì)方法,研制1300T全自動(dòng)雙向液壓磚機(jī)。首先對(duì)液壓磚機(jī)的需求進(jìn)行分析,確定總體設(shè)計(jì)方案,并采用現(xiàn)代設(shè)計(jì)方法完成對(duì)上橫梁、下橫梁、主油缸等部件的結(jié)構(gòu)設(shè)計(jì)。然后采用ANSYS對(duì)各主要部件的強(qiáng)度和剛度進(jìn)行校核,分析結(jié)果表明部件的剛度和強(qiáng)度均符合設(shè)計(jì)要求。針對(duì)下橫梁材料過(guò)剩、結(jié)構(gòu)笨重的問(wèn)題,采用DesignXplorer優(yōu)化模塊,對(duì)下橫梁進(jìn)行輕量化設(shè)計(jì),優(yōu)化后的下橫梁減重10.21%,且應(yīng)力和變形的分布更加合理,從而降低成本。為了解決主油缸疲勞損壞的問(wèn)題,通過(guò)疲勞壽命分析,得到應(yīng)力集中是影響主油缸壽命的主要因素,并在此基礎(chǔ)上,提出一種外斜直線圓角過(guò)渡線,使主油缸的壽命達(dá)到設(shè)計(jì)要求。為了探索工作頻率和外界環(huán)境對(duì)液壓磚機(jī)的影響,對(duì)機(jī)身進(jìn)行模態(tài)分析,由前六階的振型分析可知,機(jī)身中部的剛度較弱,在分析了提高剛度方法的基礎(chǔ)上,提出一種加強(qiáng)塊結(jié)構(gòu),一定程度上提高了整機(jī)的穩(wěn)定性。最后根據(jù)設(shè)計(jì)結(jié)果制作樣機(jī),現(xiàn)場(chǎng)調(diào)試及試運(yùn)行表明:該液壓磚機(jī)運(yùn)行平穩(wěn),壓制的磚坯符合生產(chǎn)要求,本文的研究成果對(duì)實(shí)際工程設(shè)計(jì)有一定的參考價(jià)值。
[Abstract]:With the encouragement and support of the new wall material industry, hydraulic brick press is developing towards large scale, high precision and automation. Aiming at the requirement of lightweight structure of large hydraulic brick press, this paper develops 1300T automatic bidirectional hydraulic brick machine with modern design method. Firstly, the requirements of hydraulic brick press are analyzed, and the overall design scheme is determined, and the structural design of upper beam, lower beam and main cylinder is completed by modern design method. Then the strength and stiffness of the main components are checked by ANSYS, and the results show that the stiffness and strength of the components meet the design requirements. Aiming at the problem of material surplus and bulky structure of the lower beam, the design Xplorer optimization module is used to design the lower beam lightweight. The weight of the optimized lower beam is reduced by 10.21, and the distribution of stress and deformation is more reasonable, thus reducing the cost. In order to solve the problem of fatigue damage of main cylinder, through the analysis of fatigue life, it is concluded that stress concentration is the main factor affecting the life of main cylinder. The life of the main cylinder meets the design requirements. In order to explore the influence of working frequency and external environment on the hydraulic brick press, the modal analysis of the fuselage is carried out. According to the analysis of the first six vibration modes, the stiffness of the middle part of the fuselage is weak. Based on the analysis of the method of improving the stiffness, A kind of strengthening block structure is proposed, which improves the stability of the whole machine to some extent. Finally, the prototype is made according to the design results, and the field debugging and trial operation show that the hydraulic brick press runs smoothly and the pressed brick blank meets the production requirements. The research results of this paper have certain reference value for the practical engineering design.
