冲裁是利用冲模在压力机上使板料分离的一种冲压工艺,包括切断、落料、冲孔、修边和切口等多种上序,广泛地应用于机械加工行业。冲裁件的工艺性,是指冲裁件对冲压工艺的适应性。为了很好地完成冲裁工艺,设计合理、经济的冲裁模是关键。尤其在冲裁力大于冲床公称压力时,选用最优方案或采取措施,设计结构合理、经济可行的冲裁模是关键。本人结合冲裁模设计的经验,以实际案例为基础谈谈冲裁力大于冲床公称压力时冲裁模的设计。 相似文献

The kinematic design of a reconfigurable miniature parallel kinematic machine is dealt with. It shows that the reconfigurability may be realized by packaging a tripod-based parallel mechanism with fixed length struts into a compact and rigid frame with which the different configurations can be formed. Utilizing a dual parameter model, the influences of the geometrical parameters on the dexterous performance and the workspace/machine volume ratio are investigated. A novel global performance index for the dimensional synthesis is proposed and optimized, resulting in a set of dimensionless geometrical parameters. 相似文献

Adaptable design aims to extend the utilities of design and product. The specific methods are developed for practical applications of adaptable design in the design of mechanical structures, including adaptable platform, interface and module designs. Adaptable redesign problems are formulated as adaptable platform design under adaptability bound constraints. Analysis tools are then suggested for the implementation of the redesign of machine tool structures, including variation techniques based sensitivity analysis, similarity-based commonality analysis, performance improvement, and adaptability measures. The specific measure of adaptability for machine tool structures is measured through the quantification of the structural similarity and performance improvement gained from adaptable design. The method provides designers with an approach that brings adaptability into the design process, with considering the cost and benefits of such adaptability. The redesign of CNC spiral bevel gear cutting machine structures has been included to illustrate these concepts and methods. 相似文献

Using virtual reality to design a new type of hydraulic support is discussed. That is how to make use of the virtual design to develop coal mining machine in practice. The advantages of virtual design are studied and the simple virtual reality system is built. The 3D parts and elements of hydraulic support are modeled with parametric design in CAD software, then exported to VR environment, in which the virtual hydraulic support is assembled, operated and tested. With the method, the errors and faults of design can be fined easily, many improvements are made and the new hydraulic support is developed successfully. 相似文献
