At present the control system is mainly crane mechanical hydraulic control,Along with the hydraulic ponents, puter technology and information technology, the development of the intelligent hydraulic crane are ing in. Then the giant can replace people do harder work for human development have can39。t estimate role. In paring the large and plex hydraulic system, the chip can take full advantage of the use of a variety of hydraulic ponents, enabling a more pact structure, seal brtter, easy to install and debug. However, a dedicated chip is strong, suefacemount hydraulic ponents and more plex holes in valve body, therefore, in accordance with the hydraulic schematic diagram of the logic of the requirements of reasonably correct chip design is a difficult and require high accuracy job.before the integrated block processing, Perform calculations on integrated block hydraulic diameter draw out the integrated block processing maps, including each side view and each Layer cutaway view, aperture, hole depth and the number of hole and hole connection is drawn into a table, convenient processing. Selection of 45 steel as blank material, determine the processing allowance, blank dimensions and tolerances. Choice processing methods reasonably, develop a process route。 draw out the machining process card and processing process card. Determine the amount of cutting, design a reasonable jig. Processing, in order to the surface after the first hole coarse and fine apart first thick hind fine the principle on integrated block surface processing and hole machining.This design has been all the teachers carefully pointing and teachings, for integrated block portion of the clear design, explain fully, but there are many flaws, such as integrated block of oil on the pipe joint and a corner impact problem, without considering the overall；Integrated block in machine installation also does not take into account.Keywords:hydraulic Manifold Block, manifold design,processing technology目錄第一章 緒論 １ １ ２ ２ ２ ２第二章 叉車的液壓系統(tǒng)原理圖 ３ ３ 叉車液壓系統(tǒng)主要參數(shù)表 ３ ４第三章 液壓系統(tǒng)的參數(shù)計(jì)算與元件的確定 ２ ２ ２ ２ 轉(zhuǎn)向缸的參數(shù)確定 ３ ３ 液壓元件的選擇內(nèi)容 ３ ３ ５第四章 液壓系統(tǒng)集成塊的結(jié)構(gòu)設(shè)計(jì) １ １第五章 液壓集成塊的加工工藝 １ １ １ １ １ ２ ２ ２ ２ ３ ３，刀具及其夾具的選擇 ５參考文獻(xiàn) ２致謝 １ 學(xué)
