Hydraulic technology is one of the fastest growing technology in mechanical equipment. Especially with the microelectronics, the combination of computer technology in recent years, so that the hydraulic technology has entered a new stage of development. Press slider drivens by the hydraulic cylinder, hydraulic parts used for punching processing, can realize the rapid decline of a slider punching down a stop rapid rise in a working cycle. Stamping technology is currently being one of the metal pressure processing method is widely used, it has the characteristics of high efficiency, good quality, energy saving, low cost, so the use of stamping technology more and more advanced industrial countries instead of cutting and other processing technology. Stamping technology is widely used in automobile, agricultural machinery, household appliances, electronic instruments, the defense industry and daily necessities such as production department. In recent years, hydraulic stamping press in improving stroke times fast technology, precision technology, active anti offset to improve the performance and reduce noise at lower cutting damping technology, energy saving hybrid drive technology installed power and synchronization technology multi-point pressure and sliding block position and transmission of NC technology progress soon, the past hydraulic and mechanical press in comparison of shortcomings is almost gone. Stamping processing equipment in the traditional, technical performance, and reliability and operation economy more and more cant adapt to the modern automobile industry, large-scale mass production automation needs.Keywords: hydraulic press hydraulic cylinder目 錄摘 要IAbstractII第1章 緒論11.1.1 液壓技術(shù)及其影響11.1.2 沖床液壓系統(tǒng)21.2 液壓傳動的工作原理及其組成部分21.2.1 液壓傳動的工作原理31.2.2 液壓傳動的組成31.3 液壓傳動的優(yōu)缺點41.3.1 液壓傳動的優(yōu)點41.3.2 液壓傳動的缺點51.5 沖壓設(shè)備發(fā)展概況及發(fā)展趨勢81.5.1 沖壓設(shè)備概述81.5.2 沖壓設(shè)備發(fā)展趨勢81.6 課題的來源及研究的目的和意義91.7 課題的研究內(nèi)容9第2章 沖床液壓系統(tǒng)分析102.1 高速沖床液壓系統(tǒng)分析102.1.1 沖床液壓系統(tǒng)圖102.1.2 高速沖床液壓系統(tǒng)工作過程112.2 系統(tǒng)基本工作參數(shù)112.2.1 最大沖載孔徑和沖載板厚的確定112.2.2 系統(tǒng)壓力選定122.2.3 周期和行程12第3章 確定執(zhí)行元件143.1 液壓缸基本參數(shù)確定143.1.1 缸筒的設(shè)計計算143.1.2 活塞桿163.1.3 液壓缸進油口尺寸173.1.4 液壓缸的密封173.1.5 液壓缸摩擦力的計算183.1.6 液壓缸基本結(jié)構(gòu)193.2 泵的選擇203.2.1 泵的排量203.2.2 泵的選用203.3 電機的選擇203.4 速度驗算203.4.1 空行時速度驗算203.4.2 沖壓板厚為1mm時速度驗算213.5 蓄能器223.5.1 蓄能器分類223.5.2 蓄能器充氣壓力P的確定223.5.3 蓄能器容量計算223.6 管路的選擇243.6.1 管路內(nèi)徑計算243.6.2 管道壁厚243.7 油箱設(shè)計253.8 冷卻器253.9 過濾器263.10 閥的選用263.10.1 比例伺服閥的選擇263.10.2 其他閥的選擇26第4章 沖床液壓系統(tǒng)結(jié)構(gòu)設(shè)計284.1 閥塊的總裝結(jié)構(gòu)圖284.2 閥塊結(jié)構(gòu)圖284.3 沖床液壓站結(jié)構(gòu)圖294.4 液壓缸結(jié)構(gòu)圖30第5章 液壓缸缸筒缸桿的有限元分析315.1 有限元基本理論分析315.1.1 有限元的發(fā)展介紹315.1.2 有限元分析的基本思想335.1.3 有限元分析基本過程345.2 ADNIA軟件介紹355.3 靜力分析365.4 總結(jié)與分析38第6章 沖床液壓站成本估算統(tǒng)計396.1 元件明細396.2 液壓站報價明細40結(jié) 論41致 謝42參考文獻43附 錄144附 錄2465
