毕业设计论文3000T自由锻液压机本体设计全套图纸.docVIP

摘 要 本设计为自由锻液压机，主缸的最大的负载设计为15000KN，该液压机主要有工作缸、回程缸、上横梁、下横梁、滑块、工作台等组成。本文重点介绍了液压机的本体设计，通过给定的参数进行计算，然后进行总体的设计方案。由于液压机的公称压力比较大，所以在选用工作缸的时候选用柱塞缸，由于工作缸是柱塞式，所以要加提升缸。采用预应力框架式结构。此外，本文对液压机进行了总体布局设计，对重要机器原件进行了结构、外形、工艺设计。 通过对液压机各个零部件的强度校核计算，保证了液压机在实际生产中的各项强度要求。 关键词　液压机；液压；毕业设计 全套图纸加153893706 Abstract The Prestressed frame type large-scale hydraulic press, the greatest master cylinder is designed to load 15000KN, the main work machine hydraulic cylinder, a return tank, on the beams, the beams, the side beams, This article focuses on the body design of the hydraulic machine, through the parameters of a given calculation and then proceed to the overall design. The nominal pressure as a result of hydraulic pressure more, so the work in the selection of choice when the cylinder piston cylinder, as a result of the piston cylinder, the cylinder to increase the return. The use of pre-heating the structure column. In addition, the hydraulic machine of the overall layout of the original machines have been an important structure, shape, process design. Through various parts of the hydraulic calculation of the intensity of checking to ensure that the hydraulic pressure in the actual production of the strength.
