内容简介：

华北科技学院毕业设计板料折弯机液压系统设计摘要：折弯机对折弯金属板料具有较高的劳动生产率和较高的折弯精度。当折弯不同厚度的板料时，应选择不同开口的V槽，若采用不同形状的上下模具，可折弯成各种形状的工件。本设计主要设计折弯机的液压系统，在整个设计过程中，不影响设计要求的情况下，本设计能用标准件的在尽量采用标准件，从而提高整个折弯机的性价比。因而本设计主要对液压系统中的液压缸和油箱进行了设计。在设计过程中我参考了很多设计手册。使我学会了很多知识，让我了解到作为一个设计工程师所必须作的事。而且我又在不影响液压缸性能的前提下进行了一些创新，使缸的制造成本有些降低。但对缸的某些复杂结构进行了简化，对于油箱的设计，我在遵守设计手册要求的前提下，增加了一些辅助功能，使油箱更趋于完善、合理。以使我在本次设计中得到更多的锻炼，更适应将来的工作。此次设计对于提高工作效率节约工作时间具有较好的意义，为向数控和智能化折弯机进行设计打好基础。关键词：液压系统；液压缸；油箱Abstract:The machine have high productivity and precision when it working on plank materials. When the machine breaking different thickness plank materials, we should select distinct molds, which have different V-groove. If use different shape up-down molds the break machine could turn plank materials into distinctive components.The design mainly relate to Hydraulic pressure system. Though the whole design, I try my best to use standard-part, if the use not effect the systems request, so that I could get higher property-price scale. So the design I do is mainly about the Hydraulic pressure vat and . Fuel tank of the Hydraulic pressure system.The design of the integrated use of the mechanical design and other courses of knowledge, analysis and mechanical design to solve the problem, further consolidate, deepen and broaden the knowledge acquired. When I design Hydraulic pressure vat and Fuel tank,I make the structure simpler and more reasonable. Of course, my change not only effect its function but also enhance it. I try my best to carry out best design.The design saves the operating time and improve the efficiency of working .It is have a better sense for us ,and build the foundation for us to design the numeric control and the intellectuali
