s cited.. Key words: explosionproof belt forming machine hydraulic transmission system lateral stamping bending processing 1167。s explosionproof belt is formed on the basis of the problems exist in mechanical, according to the requirements of parts operating, design a kind of using hydraulic transmission system for the power of the explosionproof belt forming machine. The forming machine utilizes the side stamping to carry on the bending processing to the hook. The explosionproof zone is widely used in various imaging screens, so as to prevent the explosion of the picture tube, thus avoiding all kinds of safety hazard.. Its explosive proof belt forming machine is mature, simple in structure, low in manufacturing cost, and wide range of products..In explosionproof belt forming machine design, first of all, for explosionproof belt belt material selection and forming process analysis and design of suitable mechanical structure according to and select suitable machining process。 9167。設計一臺64cm防爆帶掛鉤成形機,防爆帶的上料采用全自動送料,角度控制和掛鉤的彎曲由成形機中凸模、凹模來進行確定和加工。 防爆帶成形機設計原理的分析、確定167。由以上的敘述可知,要完成零件的加工,最關鍵的就是有能夠彎曲力的機構。 F總總的工藝力;以上即為掛鉤進行彎曲加工時,液壓缸通過彎曲機構的轉化最終作用在掛鉤上的力,該力不能小于2. 9022KN。則液壓缸內(nèi)徑計算為根據(jù)《液壓技術實用手冊》取圓整得液壓缸內(nèi)徑為=125。本系統(tǒng)采用直動式溢流閥來調(diào)節(jié)系統(tǒng)的供油壓力。在剛開始面對這次防爆帶掛鉤成形機設計的時候,我是無從下手,腦子一片空白,但經(jīng)過工廠觀看一些類似的成形機和查閱一些相關的資料,遇到問題就不斷查找資料和詢問老師,問題解決為止,使得自己對這次設計有了新的認識,并對防爆帶成形機的機構有了新的了解。更重要的是,我學到了凡事要取得成功,必須有一個良好的心態(tài),一步步堅持不懈的努力,不可操之過急,也不可灰心喪氣。 設計總結經(jīng)過一段時間的防爆帶掛鉤成形機畢業(yè)設計,任務書上的任務現(xiàn)在基本已經(jīng)完成了,本次畢業(yè)設計的結束,意味著我們的大學生活也跟著結束。(1)換向閥:是利用閥芯和閥體間的相對位置的改變來控制油液的流動方向接通或關閉油路從而控制執(zhí)行元件的啟動、停止及換向。 167。查《沖壓手冊》可得U形件的計算公式為: 式中:校正彎曲力,單位為 N; B彎曲件
