山東大學(xué)生本科生畢業(yè)設(shè)計(jì)（論文）摘 要 本機(jī)器用于剪切厚度為16mm,寬度為2500mm的鋼板。 被剪切板料強(qiáng)度以450N/mm2為準(zhǔn),如需剪切其它強(qiáng)度的板料時(shí),應(yīng)相應(yīng)減薄被剪板料的厚度。 本機(jī)器采用鋼板焊接結(jié)構(gòu),液壓傳動(dòng),氮?dú)飧谆爻?電氣控制.工作平穩(wěn)可靠,機(jī)器體積小,重量輕,剛性好,操作方便等優(yōu)點(diǎn)。由于此機(jī)器設(shè)計(jì)工作量大，設(shè)計(jì)時(shí)間的限制，以及諸多因素的影響，故選其液壓控制部分作為我的設(shè)計(jì)內(nèi)容，它包括了：如何完成剪切，如何壓料及卸料的過程。 調(diào)整刃口間隙迅速方便,機(jī)器設(shè)有前后擋料,后擋料采用機(jī)械傳動(dòng),轉(zhuǎn)數(shù)器顯示數(shù)值,并能作手動(dòng)微調(diào),調(diào)節(jié)方便可靠.前擋料采用標(biāo)尺計(jì)數(shù),擋塊定位,另外還設(shè)有燈光照明,便于劃線剪切,通過時(shí)間繼電器可任意調(diào)節(jié)上刀架的行程,以提高剪切窄板料的效率。關(guān)鍵字：剪板機(jī)；液壓；繼電器； AbstractThe machine used to cut the thickness of 1 6mm, a width of 2500mm of steel.Material strength is the clipboard to 450N/mm2 prevail, For other strength of the sheet metal shear, should accordingly be shear thinning in the thickness of material.This machine adopts steel plate welded structure, hydraulic drive, nitrogen cylinder, stead, electrical control. Smooth and reliable, machine size, light weight, rigid, and easy operation.Because of this large machine design, design time constraints, as well as a number of factors, was chosen as part of its hydraulic control the content of my design, which includes: how to complete the cut, how to press materials and unloading process.Quickly and easily adjust the blade clearance, the machine has material before and after block after block material using mechanical transmission, transfer the number of displays values, and can be manually fine-tuning, reliable and easy to adjust. Before the block material using scale count, block positioning, in addition towith lighting, convenient crossed cut, by the time relay can be adjusted on the turret of his program to improve the efficiency of cutting narrow sheet.Keywords: Shearing; hydraulic; relay;目錄第1章 緒論11.1剪板機(jī)概述11.2 剪板機(jī)的背景11.3 剪板機(jī)在國內(nèi)外的研究狀況21.4 液壓技術(shù)的發(fā)展趨勢2第2章 剪板機(jī)介紹62.1 剪板機(jī)的基本參數(shù)62.2 剪板機(jī)的工作原理62.3 剪板機(jī)的用途和分類7第3章 剪板機(jī)液壓系統(tǒng)的設(shè)計(jì)93.1 液壓傳動(dòng)定義和發(fā)展概況93.2 液壓傳動(dòng)系統(tǒng)的工作原理103.3 液壓傳動(dòng)的工作介質(zhì)133.4 確定液壓執(zhí)行元件的形式173.5分析液壓執(zhí)行元件的主要參數(shù)173.6 選擇液壓元件203.7 擬定液壓系統(tǒng)圖253.8 液壓系統(tǒng)性能驗(yàn)算273.9 液壓傳動(dòng)的優(yōu)缺點(diǎn)和應(yīng)用27第4章 控制液壓系統(tǒng)工作的電氣設(shè)計(jì)304.1 課題概述和設(shè)計(jì)要求304.2設(shè)計(jì)理念304.3電動(dòng)機(jī)的選擇314.4電氣控制線路圖的設(shè)計(jì)314.5 電器元件的選擇334.6電氣接線圖的繪制35第5章 機(jī)器的使用和要求375.1機(jī)器的操作375.2機(jī)器的潤滑375.3機(jī)器的安全技術(shù)與維護(hù)38結(jié) 論40致 謝41參考文獻(xiàn)42
