I圓盤式剪切機(jī)的設(shè)計(jì) 摘 要現(xiàn)在各國(guó)工業(yè)迅猛發(fā)展,鋼鐵企業(yè)是國(guó)民經(jīng)濟(jì)的主要支柱,它的發(fā)展?fàn)顩r很大程度上可以反映出國(guó)家的實(shí)力。現(xiàn)代鋼鐵冶金業(yè)發(fā)展的一個(gè)著眼點(diǎn)就是在對(duì)鋼材的處理速度。圓盤剪切機(jī)就是其中的一臺(tái)重要設(shè)備。圓盤剪切機(jī)通常設(shè)置在精整作業(yè)線上,用來(lái)將運(yùn)動(dòng)著的鋼板的縱向邊緣切齊或切成窄帶鋼。根據(jù)其用途可分為兩種類型:剪切板邊的圓盤剪和剪切帶鋼的圓盤剪。本文中對(duì)圓盤剪切機(jī)的設(shè)計(jì)計(jì)算是在對(duì)鞍山鋼鐵集團(tuán)公司冷軋廠 1700 橫切機(jī)組大量調(diào)研的背景下進(jìn)行的。通過(guò)對(duì)圓盤剪切機(jī)及相關(guān)設(shè)備結(jié)構(gòu)進(jìn)行了深入了解,并從材料力學(xué)、動(dòng)力學(xué)和經(jīng)濟(jì)學(xué)的角度出發(fā),對(duì)圓盤剪切機(jī)的主傳動(dòng)系統(tǒng),壓下系統(tǒng)、側(cè)間隙調(diào)整機(jī)構(gòu)進(jìn)行了設(shè)計(jì)。重點(diǎn)包括電動(dòng)機(jī)的計(jì)算選取、軸和齒輪的設(shè)計(jì),以及其他傳動(dòng)裝置和執(zhí)行機(jī)構(gòu)的設(shè)計(jì)等,同時(shí)對(duì)部分主要零部件進(jìn)行了強(qiáng)度校核。本次設(shè)計(jì)的改進(jìn)點(diǎn):首先,在徑向間隙調(diào)整機(jī)構(gòu)連桿機(jī)構(gòu),其二,側(cè)向間隙調(diào)整增加自鎖裝置。其三,寬度調(diào)整采用行星齒輪減速機(jī)。最后增加了測(cè)速機(jī)構(gòu)。本圓盤剪切機(jī)可普遍用于橫切機(jī)組、酸洗機(jī)組等。關(guān)鍵詞:圓盤剪切機(jī),帶鋼,壓下裝置,強(qiáng)度校核IIThe disc alligator shears design AbstractThe industry of various countries develops rapidly now, the steel, as the main pillar of industry, its development can reflect the national strength to a great extent. Modern steel metallurgy industry one starting point that develop in to processing speeds. Disc shears is an important equipment among them.Disc shear machine set up in finishing production line. It usually uses to cutting neat the movement steel plate longitudinal edge and cut the strip into narrow one. It can be divided into two kinds according to its use: disc shears of cut stencil plate’s side and disc shears of cut strip.The disc shears design calculation is taken in makes the massive investigation to the ANSHAN steel group Cold-rolling mill 1700 transverse cutting aircrew as the background. We have thorough understanding to the disc shears and the correlation equipment. We had very designed to the main transmission system, depress the system and gap adjustment organization, we are carry on these designs from the materials mechanics angle, dynamics and economic. The main content including electrical machinery selection, Axis and gear design, Implementing agency design and so on, and the same time, we make the optimized improvement and the intensity examination to the major parts. This design improvement spot: First, in radial clearance adjusting mechanism link motion gear, second, backlash adjustment increase self-locking installment. Third, the width control uses the planet gear speed reducer. Finally increased has measured the fast organization. This disc shears may use in the transverse cutting unit, the acid pickling unit generally and so on.Key words: Disc shear, strip, depress the system, the intensity examinationIII目 錄第一章 緒論………………………………………………………………………11.1 我國(guó)窄帶鋼生產(chǎn)現(xiàn)狀及產(chǎn)品結(jié)構(gòu)的調(diào)整…………………………11.1.1 我國(guó)窄帶鋼行業(yè)的發(fā)展現(xiàn)狀………………………………………11.1.2 產(chǎn)品結(jié)構(gòu)的調(diào)整…………………………………………………… 31.2 我國(guó)窄帶鋼生產(chǎn)狀況與市場(chǎng)演變趨勢(shì)分析………………………31.3 我國(guó)帶鋼市場(chǎng)未來(lái)發(fā)展特點(diǎn)分析……………………………………51.3.1 提高軋機(jī)的裝備水平………………………………………………61.3.2 提高廠(車間)的總體裝備水平…………………………………61.3.3 加強(qiáng)和應(yīng)用現(xiàn)代化的檢測(cè)手段……………………………………71.3.4 精整機(jī)組………………………………………………………… 71.4 圓盤剪的類型和作用…………………………………………………81.4.1 圓盤剪的類型………………………………………………………81.4.2 圓盤剪的作用………………………………………………………81.5 圓盤剪的結(jié)構(gòu)………………………………………………………… 91.6 中小型帶鋼縱剪機(jī)組設(shè)備組成…………………………………… 91.6.1 縱剪機(jī)組的設(shè)備組成……………………………………………… 91.6.2 典型設(shè)備的作用以及結(jié)構(gòu)參數(shù)的確定…………………………… 91.7 圓盤剪的類型與作用……………………………………………… 101.7.1 圓盤剪的分類…………………………………………………… 10IV1.7.2 圓盤剪的結(jié)構(gòu)分析……………………………………………… 11第二章 圓盤剪的主要參數(shù)…………………………………………………152.1 圓盤刀片尺寸………………………………………………………… 152.2 刀盤材料……………………………………………………………… 172.3 刀盤的重合量和側(cè)向間隙…………………………………………172.3.1 刀盤重合量 S………………………………………………………172.3.2 刀盤側(cè)向間隙…………………………………………………… 18第三章 圓盤剪力能參數(shù)的計(jì)算………………………………………… 193.1 剪切機(jī)構(gòu)合理性分析……………………………………………… 193.1.1 剪切力 ………………………………………………………… 193.1.1.1 理論基礎(chǔ)……………………………………………………… 193.1.1.2 剪切力計(jì)算過(guò)程 ………………………………………………213.1.1.3 剪切力矩的計(jì)算……………………………………………… 223.2 電動(dòng)機(jī)的選擇…………………………………………………………233.3 帶傳動(dòng)的設(shè)計(jì)計(jì)算……………………………………………………24第四章 圓盤剪傳動(dòng)系統(tǒng)的設(shè)計(jì)………………………………………… 264.1 傳動(dòng)方案的確定………………………………………………………264.2 傳動(dòng)齒輪的設(shè)計(jì)………………………………………………………264.2.1 選擇齒輪材料,確定許用應(yīng)力……………………………………264.2.2 確定許用彎曲應(yīng)力 ……………………………………………26FP?4.2.3 齒輪名義轉(zhuǎn)矩 T1的計(jì)算……………………………………………27V4.2.4 載荷系數(shù)的選擇………………………………………………… 274.2.5 齒輪參數(shù)的確定……………………………………………… 274.2.6 校核齒面的接觸強(qiáng)度…………………………………………… 274.2.7 幾 何 尺 寸 的 計(jì) 算………………………………………… 284.3 減速器的確定…………………………………………………………28第五章 刀軸的設(shè)計(jì)………………………………………………………… 305.1 選擇軸的材料…………………………………………………………305.2 初步估算軸徑……………………………………………………… 305.3 軸上零件的軸向定位……………………………………………… 305.4 確定各段軸徑和長(zhǎng)度……………………………………………… 315.5 軸的強(qiáng)度驗(yàn)算…………………………………………………………315.5.1 刀盤上作用力大小的確定……………………………………… 315.5.2 軸承的支反力…………………………………………………… 315.5.3 彎矩大小的確定………………………………………………… 325.5.3.1 垂直面上的彎矩……………………………………………… 325.5.3.2 計(jì)算彎矩……………………………………………………… 32第六章 其它零部件的選擇與校核………………………………………346.1 剪刀軸上的鍵的強(qiáng)度校核…………………………………………346.1.1 軸端鍵的校核…………………………………………………… 346.1.2 鍵 28X32 的校核……………………………………………………346.1.3 齒輪軸上鍵的校核……………………………………………… 346.2 聯(lián)軸器的選擇…………………………………………………………34第七章 PLC 的控制系統(tǒng)…………………………………………………367.1 關(guān)于 PLC 的總論述……………………………………………………3VI67.2 關(guān)于主控制器 CPU 的選擇和 plc 的選擇………………………367.3 關(guān)于 plc 控制器邏輯控制器的電路的設(shè)計(jì)……………………367.4 輸入輸出……………………………………………………………… 367.1 程序流程電路設(shè)計(jì)……………………………………………………367.1 關(guān)于 PLC 的程序控制………………………………………………36第八章 結(jié)束語(yǔ)………………………………………………………………… 37
