REXROTH繼電器操作說明: 首先用于安全保護時,將壓力繼電器設(shè)置在夾緊液壓缸的一端,液壓泵啟動后,首先將工件夾緊,此時夾緊液壓缸的右腔壓力升高,當(dāng)升高到壓力繼電器的調(diào)定值時,壓力繼電器動作,發(fā)出電信號使2YA通電,于是切削液壓缸進刀切削。在加工期間,壓力繼電器微動開關(guān)的常開觸點始終閉合。若工件沒有夾緊,壓力繼電器2斷開,于是2YA斷電,切削液壓缸立即停止進刀,從而避免工件未夾緊被切削而出事故。 其實用于控制執(zhí)行元件的順序動作時,液壓泵啟動后,首先2YA通電,液壓缸左腔進油,推動活塞方向右移。當(dāng)碰到限位器(或死擋鐵)后,系統(tǒng)壓力升高,壓力繼電器發(fā)出電信號,使1YA通電,高壓油進入液壓缸的左腔,推動活塞右移。這時若3YA也通電,液壓缸的活塞快速右移;若3YA斷電,則液壓缸的活塞慢速右移,其慢速運動速度由節(jié)流閥調(diào)節(jié)。 再次用于液壓泵卸荷時,壓力繼電器不是控制液壓泵停止轉(zhuǎn)動,而是控制二位二通電磁閥,將液壓泵5輸出的壓力油流回油箱,使其卸荷。 最后用于液壓泵的啟閉時,有兩個液壓泵,高壓小流量泵,低壓大流量泵。當(dāng)活塞快速下降時,兩泵同時輸出壓力油。當(dāng)液壓缸活塞桿抵住工件開始加壓時,壓力繼電器在壓力油作用下發(fā)出動作,觸動微動開關(guān),將常閉觸點斷開,使液壓泵停轉(zhuǎn)。在加工過程中減慢液壓缸的速度,同時減少動力消耗。
