【摘要】：自上世紀(jì)五十年代推出螺桿式塑料注射成型機(jī)至今，由注射成型工藝生產(chǎn)的塑料制品已經(jīng)占據(jù)塑料制品總數(shù)的80%之多，注射成型機(jī)作為一種重要的塑料加工設(shè)備，其產(chǎn)量仍在逐年增加。近年來(lái)，隨著全球能耗問(wèn)題的日漸突出和人們環(huán)保意識(shí)的逐漸增強(qiáng)，具有節(jié)能、精密及高速穩(wěn)定等優(yōu)勢(shì)的全電動(dòng)注塑機(jī)已經(jīng)打破了傳統(tǒng)液壓注射成型機(jī)壟斷行業(yè)的局面。而在這一領(lǐng)域，我國(guó)目前尚不具有完全自主知識(shí)產(chǎn)權(quán)的研發(fā)生產(chǎn)能力。 本課題圍繞“華中8型”高檔數(shù)控系統(tǒng)展開(kāi)工作，通過(guò)數(shù)控系統(tǒng)二次開(kāi)發(fā)的方式嘗試突破全電動(dòng)注塑機(jī)專用數(shù)控系統(tǒng)中的若干關(guān)鍵技術(shù)，本文主要針對(duì)全電動(dòng)注塑機(jī)專用數(shù)控系統(tǒng)的鎖模機(jī)構(gòu)運(yùn)動(dòng)控制以及料筒加熱溫度控制這兩個(gè)關(guān)鍵技術(shù)進(jìn)行了深入的研究工作。 本文在完成控制系統(tǒng)整體設(shè)計(jì)的基礎(chǔ)上對(duì)肘桿式開(kāi)鎖模機(jī)構(gòu)進(jìn)行了力學(xué)分析，采用狀態(tài)機(jī)編程對(duì)開(kāi)鎖模機(jī)構(gòu)的功能實(shí)現(xiàn)方案進(jìn)行了詳細(xì)的分析和研究，完成了開(kāi)鎖模機(jī)構(gòu)的壓力控制及運(yùn)動(dòng)控制，實(shí)現(xiàn)了全電動(dòng)注塑機(jī)生產(chǎn)需要的若干特殊功能；在料筒加熱模塊的溫度控制方面，通過(guò)模糊PID的控制方法達(dá)到了較為理想的實(shí)際效果，，提出了PWM信號(hào)均勻輸出的算法，并對(duì)料筒的解耦控制和熱力學(xué)特性進(jìn)行了初步的分析。實(shí)驗(yàn)表明，本文所做的工作已初步了滿足全電動(dòng)注塑機(jī)實(shí)際生產(chǎn)的基本要求。
[Abstract]:Since the introduction of the screw plastic injection molding machine in the 1950s, the plastic products produced by the injection molding process have accounted for more than 80% of the total number of plastic products. The injection molding machine is an important plastic processing equipment. Its output is still increasing year by year. In recent years, with the increasing global energy consumption and the increasing awareness of environmental protection, the all-electric injection molding machine with the advantages of energy saving, precision and high speed stability has broken the monopoly situation of traditional hydraulic injection molding machine. But in this field, our country does not have completely independent intellectual property right research and development production capacity at present. This paper focuses on the high-grade CNC system "Huazhong 8", and attempts to break through some key technologies in the special NC system of all-electric injection molding machine by the way of secondary development of CNC system. In this paper, the motion control of the locking mechanism and the temperature control of the cylinder heating in the NC system of all-electric injection molding machine are studied in depth. Based on the whole design of the control system, the mechanical analysis of the locking mechanism with elbow rod is carried out in this paper, and the function realization scheme of the locking mechanism is analyzed and studied in detail by state machine programming. The pressure control and motion control of the locking mechanism are completed, and some special functions for the production of all-electric injection molding machine are realized. The fuzzy PID control method is used to achieve ideal practical results. An algorithm for uniform output of PWM signals is proposed, and the decoupling control and thermodynamic characteristics of the barrel are preliminarily analyzed. The experimental results show that the work done in this paper has met the basic requirements of the practical production of all-electric injection molding machine.
