Abstract
The hydraulic brake is one of the applied broadest equipment in the productions, and also the ideal forming technological equipment.Especially when the system of hydraulic brake realized the adjustment to the press, travelingscheduleand speed, the equipment not only completes the processing of the complex and asymmetrical work-pieces, and moreover the rate of its rejection is very low, comparing with the machine-finishing system, which has the enormous superiority.In the resent years, with the development of the microelectronic and hydraulic technology, the hydraulic brake has the further development, whose high-tech content is increasing, and the numerous types had controlled by the CNC or PC machine which increases the processingqualityand the productivity.
At first, this paper as a whole carries the design and the essential examination on the hydraulic brake.Second, it carries on the preliminary design to the entire hydraulic control system, and the computation to the main parameters of its master cylinder, then analyses the obtained results.Thus it enables the master cylinder of the hydraulic brake to satisfy the request of the product technique, and enhances its standard overall, which causes its design level on a new stair.This design is mainly in the view of different technological requests, according to the main structures of the equipment, the force sizes of the master cylinder and the request of the working conditions to choose the kinds of every part.At the same time, it involves the choices of hydraulic cylinder's support pattern and piston and active crossbeam connection pattern and guide sleeve and seal,enhancingthe hydraulic press whole use intensity and the lifeandcausingthe craft precision to conform to the request goal productions.
摘要
液压机是制品成型生产中应用最广的设备之一，也是理想的成型工艺设备，特别是当液压机系统实现具有对压力、行程、速度单独调整功能后，不仅能实现对复杂工件以及不对称工件的加工，而且，废品率非常低，与机械加工系统相比，有极大的优越性。近年来，随着微电子技术、液压技术等的发展，液压机有了更进一步的发展，其高技术含量增多，众多机型已采用CNC或PC机来控制，提高了产品加工质量和生产率。
首先，本论文从总体上对液压机本体结构，及主要结构部件进行设计及必要的校核。其次，对整个液压控制系统进行初步设计，对液压机主缸主要参数进行计算，并对所得结果进行分析、验算。从而力争使液压机主缸能够满足生产工艺要求，并从整体上提高液压机的工艺水准，使液压机设计水平更上一个新的台阶。本次设计主要针对不同工艺要求下，根据液压机总体结构，主缸的推力大小及工作条件的要求来对液压缸的部件类别进行选择，同时涉及到液压缸的支撑型式及活塞与活动横梁的连接型式和导套及密封件等进行选择，力求达到提高液压机整体使用强度及寿命，同时使工艺精度符合生产要求的目的。
