Reinforcing steel cutting machine into mechanical transmission and hydraulic transmission of two. Mechanical transmission reinforced cutting machine, working mostly used as a V-belt drive motor and gear drive slow down after two, driven crankshaft rotation, promoting the crankshaft and connecting rod to move the slider blade in the frame of the chute in a reciprocating linear motion So that the activities of the blade and a fixed blade and cut off the wrong steel. GQ40B-steel cutter, cut its movement from one type of linkage to complete the crankshaft. However, due to cut off the small inner cavity of the body, in the assembly when the crankshaft link more difficult. Especially in the use of a fault in need of repair, demolition crank link more difficult to repair a big change, so do not change the function of the equipment under the circumstances, we crank linkage has made some improvement. The improved structure of the cam directly from the body of the aircraft registered in the hole and packed out. Without dismantling the link, greatly simplifies the assembly, reduce labor intensity of workers. But also greatly facilitate the maintenance, has also simplified the process of parts and achieved good economic returns.Keywords Reinforcing steel cutting machine Cam Crankshaft Linkage目錄1緒論11.1鋼筋切斷機(jī)的作用11.2鋼筋切斷機(jī)的機(jī)理11.2.1壓入變形階段11.2.2剪切滑移階段21.2.3剪切滑移階段作用力分析31.2.4剪切全過程剪力分析41.2.5綜合分析41.3鋼筋切斷機(jī)理分析71.3.1目前鋼筋切斷機(jī)存在的問題91.3.2鋼筋切斷機(jī)前景102電動機(jī)的選擇112.1計算剪切力P112.2切斷機(jī)匹配電動機(jī)功率理論計算113減速器的設(shè)計133.1傳動比的計算與分配133.2計算傳動裝置的運(yùn)動和動力參數(shù)133.3帶的選擇143.3.1帶的計算143.3.2帶的根數(shù)確定153.4齒輪的設(shè)計及模數(shù)的選擇153.4.1第一級齒輪傳動設(shè)計153.4.2第二級齒輪傳動設(shè)計方法同第一級設(shè)計173.5軸徑的選擇以及軸承的選擇193.5.1軸徑的計算193.5.2軸的校核203.6滾動軸承的選擇計算233.7標(biāo)準(zhǔn)件244連桿的設(shè)計255提高強(qiáng)度的幾種方法275.1機(jī)體強(qiáng)度提高的設(shè)計275.2改變壓刀結(jié)構(gòu)285.3其他部件的改進(jìn)設(shè)計286鋼筋切斷機(jī)強(qiáng)度計算參考306.1機(jī)體額口的強(qiáng)度計算306.2應(yīng)力計算316.2.1正應(yīng)力計算316.2.2計算剪切力P316.3計算剪切力P326.3.1計算正應(yīng)力326.3.2計算最大應(yīng)力326.3.3試棒326.4測試方法326.4.1剪切力的測量326.4.2應(yīng)力測量336.4.3測試結(jié)果和理論計算分析情況對比分析337機(jī)械式鋼筋切斷機(jī)調(diào)整及保養(yǎng)的使用357.1鋼筋切斷機(jī)的使用調(diào)整357.2保養(yǎng)377.3安全一般規(guī)定37結(jié)論38致謝39參考文獻(xiàn)40附錄41附錄141附錄2464
