3 mechanical principles
Presses are usually driven by a motor through the friction disc flywheel rim leaving the flywheel rotates, so this press known as friction press, China's largest cattle friction press is 25 megabytes. Larger size presses with hydraulic system drives the flywheel, called hydraulic screw press, the maximum size of 125 megabytes cattle. Later appeared with an electric motor directly drives the flywheel presses, It's compact, less transmission links, due to the frequent change of control of the higher electrical requirements, and requires special motors.
Rotary presses no fixed lower dead point of the larger die forgings, can repeatedly blow molding can be singles, and even play jog. Strike force and deformation of the workpiece on large deformation hitting power, small deformation (such as cold hit) when combating force. In these respects, it is similar to the hammer. But it's a slider low speed (about 0.5 m / sec, 1/10 only hammer), the striking force through a closed rack, so smooth, vibration is much smaller than the hammer, do not need a great foundation. Presses equipped with skid insurance agencies, the maximum impact force limited to two times the nominal pressure to protect the safety equipment.
The lower forging presses are equipped with top of the device. Both screw press forging hammer, forging machinery and other mechanical presses role, universal and strong, can be used for forging, stamping, deep drawing processes. Furthermore, screw press, friction press particularly simple structure, easy to manufacture, it is widely used. Screw press drawback is lower productivity and mechanical efficiency.

3.機(jī)械原理
壓力機(jī)通常由電動(dòng)機(jī)通過(guò)摩擦盤(pán)帶動(dòng)飛輪輪緣而使飛輪旋轉(zhuǎn)，所以這種壓力機(jī)又稱摩擦壓力機(jī)，中國(guó)最大的摩擦壓力機(jī)為25兆牛。更大規(guī)格的壓力機(jī)用液壓系統(tǒng)驅(qū)動(dòng)飛輪，稱為液壓螺旋壓力機(jī)，最大規(guī)格的有125兆牛。后來(lái)又出現(xiàn)用電機(jī)直接驅(qū)動(dòng)飛輪的電動(dòng)壓力機(jī)，它的結(jié)構(gòu)緊湊，傳動(dòng)環(huán)節(jié)少，由于換向頻繁，對(duì)控制電器要求較高，并需要特殊電機(jī)。
旋壓力機(jī)無(wú)固定下死點(diǎn)，對(duì)較大的模鍛件，可以多次打擊成形，可以進(jìn)行單打、連打和寸動(dòng)。打擊力與工件的變形量有關(guān)，變形大時(shí)打擊力小，變形?。ㄈ缋鋼簦r(shí)打擊力大。在這些方面，它與鍛錘相似。但它的滑塊速度低（約0.5米/秒，僅為鍛錘的1/10），打擊力通過(guò)機(jī)架封閉，故工作平穩(wěn)，振動(dòng)比鍛錘小得多，不需要很大的基礎(chǔ)。壓力機(jī)裝有打滑保險(xiǎn)機(jī)構(gòu)，將最大打擊力限制在公稱壓力的2倍以內(nèi)，以保護(hù)設(shè)備安全。
壓力機(jī)的下部都裝有鍛件頂出裝置。螺旋壓力機(jī)兼有模鍛錘、機(jī)械壓力機(jī)等多種鍛壓機(jī)械的作用，萬(wàn)能性強(qiáng)，可用于模鍛、沖裁、拉深等工藝。此外，螺旋壓力機(jī)，特別是摩擦壓力機(jī)結(jié)構(gòu)簡(jiǎn)單，制造容易，所以應(yīng)用廣泛。螺旋壓力機(jī)的缺點(diǎn)是生產(chǎn)率和機(jī)械效率較低。

一臺(tái)干凈的壓力機(jī)能使操作者或維護(hù)人員在問(wèn)題發(fā)生時(shí)就能很快發(fā)現(xiàn)。比如漏油，漏氣，斷裂等等，如果壓力機(jī)是清潔的，那么很簡(jiǎn)單就能找出其位置。
5.4 確保壓力機(jī)處于平衡位置
得到精密平衡的壓力機(jī)能夠更好地工作，因而最好每年進(jìn)行一次檢查。氣動(dòng)系統(tǒng)擔(dān)負(fù)著氣動(dòng)制動(dòng)器和平衡系統(tǒng)的運(yùn)轉(zhuǎn)，需要檢查是否存在氣體泄漏，因?yàn)椴壳‘?dāng)?shù)臍鈮耗苡绊懼苿?dòng)器及平衡系統(tǒng)的性能，而他們控制著壓力機(jī)的停止時(shí)間，一旦出現(xiàn)問(wèn)題將會(huì)使操作者和設(shè)備陷入危險(xiǎn)。此外，所有的氣動(dòng)系統(tǒng)都有調(diào)節(jié)器，潤(rùn)滑器和儲(chǔ)水器。在氣體管線中積累的水，應(yīng)該每天排除.
5.5 一段時(shí)間更換潤(rùn)滑油和濾網(wǎng)
對(duì)壓力機(jī)潤(rùn)滑系統(tǒng)不適當(dāng)?shù)木S護(hù)也是發(fā)生壓力機(jī)停機(jī)的主要原因之一，出于一些原因，許多壓力機(jī)操作員在對(duì)配有帶濾網(wǎng)的循環(huán)油料系統(tǒng)操作時(shí)不定期更換濾網(wǎng)。應(yīng)該確保在更換油料的同時(shí)更換濾網(wǎng)，平時(shí)也需經(jīng)常更換。
5.6 機(jī)械壓力機(jī)維護(hù)的關(guān)鍵
對(duì)于一項(xiàng)機(jī)械壓力機(jī)日常維護(hù)項(xiàng)目來(lái)說(shuō)，哪方面是最重要的呢？答案是操作員。所有的壓力機(jī)維護(hù)及問(wèn)題查找到開(kāi)始于操作員，操作員經(jīng)常能夠很早地發(fā)現(xiàn)壓力機(jī)的問(wèn)題，防止對(duì)壓力機(jī)部件產(chǎn)生的重大，持續(xù)破壞。操作員能夠通過(guò)注意壓力機(jī)發(fā)出的奇怪聲響；不正常的溫升，煙霧，某些部分出現(xiàn)的碎屑或金屬顆粒；以及泄漏的管線發(fā)現(xiàn)其問(wèn)題。每天操作員應(yīng)該自問(wèn)一些問(wèn)題，通過(guò)檢查后記錄回答，從而保持長(zhǎng)期的維護(hù)記錄。
6 安裝方法
用戶將壓力機(jī)運(yùn)到安裝地點(diǎn)后，打開(kāi)包裝箱，然后根據(jù)說(shuō)明書(shū)來(lái)進(jìn)行安裝工作，將壓力機(jī)放在已打好的水泥地基上，用水平儀在機(jī)身工作臺(tái)上左右前后進(jìn)行檢驗(yàn)，水平度要求每1 000 毫米的長(zhǎng)度上允許0 . 20 毫米，如有不平用料鐵進(jìn)行調(diào)整，直到符合要求為止。地基圖見(jiàn)圖十。待水泥凝固后，應(yīng)均勻的擰緊地腳螺打螺經(jīng)理（M24 ) ，用水平儀檢查機(jī)身工作臺(tái)的水平度，壓力機(jī)必須在基礎(chǔ)徹底凝固才能開(kāi)始工作。壓力機(jī)安裝完畢后，應(yīng)仔細(xì)地用煤油將壓力機(jī)加工表面上的銹油洗去
煤油不要落在油漆表面上，以免油漆受損。應(yīng)小心的將凸肩和凹陷處清洗干凈，清洗后用棉紗擦干，涂上一層薄薄的潤(rùn)滑油。并檢查各潤(rùn)滑孔是否暢通，不得堵塞現(xiàn)象。安好后，壓力機(jī)應(yīng)裝上可靠的接地線
