Molding process and quality evaluation of soft consolidated pressure grinding wheel

为达到软固结气压砂轮所具有的效率高、质量可靠、工艺简单、可控性强的生产要求,将气压砂轮成型制备系统技术应用到软固结气压砂轮的制作中,该系统由注料压模成型系统、取件输送系统和表面固化系统3个部分组成。开展了气压砂轮固有质量、加工质量和损失质量的分析,建立了气压砂轮质量概念模型,提出了气压砂轮质量评价方法;应用机器人辅助光整加工平台,对不同规格气压砂轮进行了光整加工试验研究。研究结果表明,该质量评价体系验证了气压砂轮的质量,为气压砂轮的产业化奠定了基础,具有明显的创新性与实用性。

In order to achieve the equipments of high efficiency, reliable quality, simple technology and better controllability in production requirements of soft consolidated pressure grinding wheel, the kind of molding preparation system for pressure grinding wheel was investigated, which including three parts of material feeding ＆ moulding system, taking ＆ conveyor system and surface curing system. After the analysis of the inherent quality, processing quality and loss quality, the quality conceptual model of pressure grinding wheel was established. A method was presented to evaluate the quality of pressure grinding wheel. With the robot auxiliary processing platform, pressure grinding wheel on different specifications was used to do experimental research in order to gain the quality evaluation standard for reference. The experimental results show that the quality evaluation system verifies the pressure grinding wheel and it lays the foundation for the quality of the industrialization of the pressure grinding wheel with the obvious innovation and practical applicability.
