Mechanical press movements smooth, reliable, widely used in stamping, extrusion, fing and powder metallurgy processes. The content of this research for Fing Machine intermittent transmission case, and its working principle is: by the triangle belt drive motor through the large pulley (usually doubles as a flywheel), after Globoidal cam indexing drive and clutch plates, so that the slider crank drive and convex downlink linear mode. Fing a return after the pletion of the slider upward, the clutch was torn off and the brake at the same time connected to the slider to stop dead in the vicinity. In order to achieve intermittent drive, require the use of space and subdegree Globoidal cam disk, that is, a rotating cam to every point of view only a certain work. Mechanical Press is the impact of the load, that is, a working cycle in the work of fing a short time. Shortterm maximum power than the big ten times more than average power, and therefore need to set the flywheel in the transmission system. By the power of choice to start the motor, the flywheel to the rated speed operation, energy savings. Contact punch began fing billet work, the drive motor power less than the load, lower speed, the flywheel kiic energy released from savings to pensate. Upon pletion of fing, reaccelerate the flywheel energy savings, to prepare for the next use. Mechanical press on the clutch and brake linkage between the device has to ensure that a certain brake clutch engagement before the release, brake before the clutch brake a certain detachment. The operation of the mechanical press is divided into continuous, singleand microtrip, mostly by controlling the clutch and brake to achieve. Production over the possibility of a work force that presses the public phenomenon. In order to ensure equipment safety, in press overload protection device installed.Key words: Mechanical press。 生產(chǎn)中，有可能發(fā)生超過壓力機(jī)公稱工作力的現(xiàn)象。 機(jī)械壓力機(jī)上的離合器與制動(dòng)器之間設(shè)有連鎖裝置,以保證離合器接合前制動(dòng)器一定松開,制動(dòng)器制動(dòng)前離合器一定脫開。凸模接觸坯料開始鍛壓工作后，電動(dòng)機(jī)的驅(qū)動(dòng)功率小于載荷，轉(zhuǎn)速降低，飛輪釋放出積蓄的動(dòng)能進(jìn)行補(bǔ)償。短時(shí)的最大功率比平均功率大十幾倍以上，因此在傳動(dòng)系統(tǒng)中需設(shè)置飛輪。 為了實(shí)現(xiàn)間歇傳動(dòng)，需要采用空間弧面凸輪和分度盤，即凸輪每旋轉(zhuǎn)一轉(zhuǎn)只有一定的角度參加工作。本課題研究的內(nèi)容為鍛壓機(jī)的間歇傳動(dòng)機(jī)構(gòu)，其工作原理為：由電動(dòng)機(jī)通過三角皮帶驅(qū)動(dòng)大皮帶輪（通常兼作飛輪）,經(jīng)過弧面凸輪帶動(dòng)分度盤,驅(qū)動(dòng)曲軸使滑塊直線下行。聊城大學(xué)東昌學(xué)院本科生畢業(yè)論文（設(shè)計(jì)） 題 目： 鍛壓機(jī)間歇傳動(dòng)機(jī)構(gòu)設(shè)計(jì) 專業(yè)代碼： 0 8 0 2 5 1 作者姓名： 董 志 飛 學(xué) 號(hào)： 20220020452 單 位： 聊城大學(xué)東昌學(xué)院 指導(dǎo)教師： 崔 傳 輝 2022 年 5 月 15 日目 錄 言 ...................................................1 發(fā)展史及近幾年來國內(nèi)外發(fā)展?fàn)顩r .................................1 設(shè)計(jì)方案的可行性分析和預(yù)期目標(biāo) .................................2 設(shè)計(jì)方案的技術(shù)參數(shù) .............................................3 ...........................3 電動(dòng)機(jī)的選用 ...................................................3 帶輪的設(shè)計(jì)計(jì)算 .................................................4 帶輪的計(jì)算方法 .............................................4 帶輪的材料選用 .............................................5 帶輪的結(jié)構(gòu)設(shè)計(jì) .............................................5 小帶輪連接件的選用 .........................................5 弧面凸輪及分度盤設(shè)計(jì)計(jì)算 .......................................6 弧面凸輪及分度盤運(yùn)動(dòng)參數(shù)計(jì)算[4] ............................6 弧面凸輪及分度盤主要幾何尺寸計(jì)算 ...........................7 弧面凸輪的結(jié)構(gòu)圖 ...........................................8 離合器及制動(dòng)器的選用 ...........................................8 離合器的選用 ...............................................8 制動(dòng)器
