【正文】 AbstractCold shear machines are usually used to e to carry on the machine equipments that slices the head, slices the tail and to slice appointed dimension of the piece in the rolling metallurgy industry. The conduct and actions shears to slice the machine in of a kind of, cold shear the machine in the metallurgy, aviation, industry of defenses, and print the etc., the light industry all has the extensive application.Earlier period of cold shear the machine because the structure is more bulky and did not change the knife the device quickly, cause produce the efficiency lower, the quantity of the product is also not high. For this, we designed the structure to even connect the pole for the crank of the tightly packed up the inclined blade of slice type shears to slice the machine.This shear to slice the machine to mainly include to shear to slice the part and spread to move the part. Shear to slice the part adoption up the inclined blade razor blade of slice type shears to slice the way, lowering to shear to slice the dint consumedly. Spread to move the part adoption electrical engineering to arouse to decelerate the machine to replace through the adapter coupling to take to spread to move originally, avoid because of the power loss that the flexibility glide bring, adopt of a dish type friction clutch control deceleration machine and the open type wheel gear to leave to match, arouse to connect the top and bottom of the pole through the song stalk sport to plete to shear to slice the action.The characteristics of that anization lies in to replace the flywheel with the big wheel gear, the adapter coupling spreads to move to replace to take to spread to move.Should shear the production efficiency of slice the machine higher and the production cost is lower, being applicable to the medium small scaled and good material production line or no slot steel pipe billet to shear to slice.Keyword: A dish type of rubs clutch，Brace and link，Oblique blade，Shear machine，The adapter coupling transmission目 錄摘　 要 ....................................................................IAbstract.................................................................II1 緒論 ....................................................................1 剪切機的用途 ........................................................1 剪切機的分類 ........................................................1 斜刃剪切機.......................................................1 平行剪刃剪切機...................................................2 圓盤式剪切機.....................................................3 沖型剪切機.......................................................3 聯(lián)合剪切機.......................................................3 型材棒料剪切機...................................................3 剪切機常見事故 ......................................................4 傳動方案的選擇和評述 ................................................4 剪切機機械傳動裝置的作用及選擇...................................4 剪切機機械傳動裝置的防護.........................................5 剪切機機械傳動裝置的過載保護裝置.................................52 剪切機參數(shù)及電機容量的選擇 ..............................................7 設(shè)計的基本要求 ......................................................7 剪切機構(gòu) .............................................................7 主要參數(shù)的確定 ......................................................8 刀片傾斜角 α ....................................................8 刀片尺寸.........................................................8 剪刃行程.........................................................8 剪切次數(shù).........................................................9 剪切力的計算與校核 ..................................................9 電機功率的選擇 .....................................................12 靜力矩的組成....................................................13 ???fH?曲線 ...................................................14 剪切力矩 pM和摩擦力矩 f.......................................14 電動機功率的計算................................................183 傳動方案 ...............................................................193. 1 傳動步驟 ...........................................................19 電動機..........................................................19 聯(lián)軸器..........................................................19 齒輪............................................................20 離合器..........................................................20 曲軸............................................................21 曲柄連桿機構(gòu)....................................................21 壓板機構(gòu)........................................................22 上刀臺平衡機構(gòu)..................................................224 主要零件的強度校核 .....................................................23 聯(lián)軸器的計算 .......................................................23 聯(lián)軸器的類型的選擇..............................................23 聯(lián)軸器的載荷計算................................................23 齒輪強度的校核 .....................................................23 曲軸的強度校核 .....................................................295 潤滑方式的選擇 .........................................................31 潤滑 ...............................................................31 滑動軸承的潤滑..................................................31 大齒輪的潤滑....................................................31 離合器的潤滑....................................................31 減速器的潤滑....................................................31 上刀架曲柄連桿機構(gòu)滑塊的潤滑....................................32 添加劑及其作用 .....................................................32 滑方法 .............................................................32 潤滑脂的優(yōu)點和選擇注意事項 .........................................326 對控制系統(tǒng)的要求 .......................................................33 剪切力控制 .........................................................33 電動機的過載控制 ...................................................337 設(shè)備的環(huán)保與經(jīng)濟性分析..................................................34
