【摘要】：为提高大采高液压支架结构件和机械加工件质量以及装配后整机的力学性能和使用寿命,对现有液压支架生产制造工艺进行改进。以ZY15000/29/63大采高液压支架为研究对象,分析了现有液压支架生产制造工艺在自动化控制、实时监测方面的不足,据此制定了合理的液压支架结构件选材、自动整版下料、先进坡口加工和焊接工艺,大直径立柱、缸筒、活柱等机械加工件加工工艺以及支架的装配、检验试验工艺。研究表明:制定的板材整体喷丸、整版下料切割、焊接实时监测以及焊前、焊后处理等方法,能有效提高结构件性能,刮削、滚光复合加工方法能显著提高缸筒加工精度,样机压架试验技术能促进产品设计优化。
[Abstract]:In order to improve the quality of structural parts and mechanical workpieces of hydraulic support for large mining height and the mechanical properties and service life of the whole machine after assembly. The production and manufacturing process of the existing hydraulic support is improved. Taking the ZY15000/29/63 large mining height hydraulic support as the research object, the automatic control of the production and manufacture process of the existing hydraulic support is analyzed. According to the shortcomings of real-time monitoring, reasonable material selection of hydraulic support structure, automatic plate cutting, advanced groove processing and welding technology, large diameter column, cylinder cylinder are established. The machining process of mechanical workpiece such as movable column and the assembly and test technology of support. The research shows that: the whole plate shot peening, whole plate cutting, welding real-time monitoring, pre-welding, post-welding treatment and so on. It can effectively improve the performance of structural parts. The machining accuracy of cylinder can be improved significantly by the combined machining method of scraping and rolling. The test technology of the prototype press frame can promote the optimization of product design.
