【正文】 ed side machine’s system of the hydraulic pressureAbstractThe curved side machine belongs to the stamping engine equipments, it adoptions hydraulic pressure to spread to move, it mainly is apply to the side of curving material of the plank type, such as the exdoor of the refrigerator plank and so on, This curved side machine’s work purpose is to make mm the thick steel plate into a slot form, its work process is as follows: Receiving material(Be plete by the air cylinder)→Open the molding tool→Curving side in upright→Curving side in level→The level curved side urn retract→The upright curved side urn retract→Cose the molding tool, The whole work course requests pletion in 20 seconds. Its main work parameter have: The upright curved side urn and the level curved side urn route of travel all for the 100 mm。其中,豎直壓緊部件是彎邊裝置的重要組成部分,它的主要作用是壓料和進行第一次沖壓彎曲。此彎邊機的主要組成部分主要有泵站、床身、立柱、豎直和水平彎邊部件、豎直壓緊部件及定位模部件等。學士學位論文學士學位論文彎邊裝置液壓系統(tǒng)設計摘 要彎邊裝置屬于沖壓機械設備,它采用液壓傳動,主要應用于對板型材料彎邊,如冰箱的前門板等,其工作過程如下:接料(由氣缸完成)到模具上→開?!Q直彎邊→水平彎邊→水平彎邊缸縮回→豎直彎邊缸縮回→定位模合攏閉模,整個工作循環(huán)要求在20s之內(nèi)完成。它的主要工作參數(shù)有:豎直彎邊缸及水平彎邊缸行程均為100mm;定位模缸的行程為80mm。泵站總共有10個油缸組成,傳動是平穩(wěn)連續(xù)的。本彎邊裝置從結(jié)構(gòu)上看,元件單位傳遞的功率大,結(jié)構(gòu)簡單,布局靈活,能迅速換向和變速,元件易實現(xiàn)系列化和標準化。 the route of travel of the fixed position mold urn is 80 mm. This curved side machine mainly constitutes of the pump station,lathe bed and pillar,the upright and level curved side parts,the upright impaction parts and the fixed position mold parts etc. The pump station has 10 oil urns to constitute altogether,its spreading to move is steady and these the upright impaction parts is the curved side machine’s importance constitutes part. its main function is to squeeze material and carry on hurtling to press flection for the first time. According to the curved side machine’s structure, the power that the ponent unit deliver is high, the structure is simple, the layout is vivid, can change quickly the direction and speed, the ponent carries out spectrumizes and standardizes easily.Keywords Curving side in upright。 the impaction parts。我所進行的課題為《彎邊裝置液壓系統(tǒng)設計》,主要是泵站的設計,它屬于液壓傳動范疇。自1946年從國外引進一些液壓元件生產(chǎn)技術(shù),同時進行自行設計液壓產(chǎn)品以來,我國的液壓元件已從低壓到高壓形成系列化,在各種機械上的得到廣泛應用。本世紀60年代后原子能技術(shù)、空間技術(shù)和計算機技術(shù)的發(fā)展將液壓技術(shù)推向前進,是它發(fā)展成包括傳動、控制、監(jiān)測在內(nèi)的一門完整的自動化技術(shù)。它采用液壓傳動的程度已
