【摘要】：粉末成型机是粉末冶金中重要的设备之一,随着我国粉末冶金行业的高速发展,粉末成型机的智能化程度低已经成为制约其发展的重要原因。为了提高粉末成型设备的智能化程度,急需一套能实现该设备远程监控与服务的系统,在线监控设备的运行状态,及时发现故障并提供远程服务。本文以HPP8500型粉末成型机为研究对象,研发了大型粉末成型设备的远程监控与服务单元。文中分析了远程监控、粉末成型机调模和下冲回弹装置的研究现状,对大型粉末成型设备的远程监控与服务单元进行了总体设计。研发了基于STM32微控制器的下位机现场监控前端,该监控前端可以获取粉末成型机的机器参数、压制参数、运行参数并通过3G通讯方式,传输到远程服务平台,而上位机远程服务平台利用C#进行开发,整个系统实现了远程辅助调模、电控下冲回弹、远程状态监测、远程控制等功能。在远程监控和服务单元的基础上,针对粉末成型设备在使用中遇到的调模困难问题,提出了基于优选法和模糊控制相结合的调模算法;对粉末成型设备在脱模过程中,出现的产品开裂问题,设计了电控下冲回弹装置。并最终在HPP8500型粉末成型机上对上述调模方法和电控回弹装置进行了验证。结果表明,上述方法有效地提高了调模效率,降低了调模难度,提高了产品的合格率。研究设计的远程监控与服务单元已经在粉末成型机上得到了初步应用,实现了对HPP8500型粉末成型机远程监控与服务的预期目标,提高了传统机械式粉末成型压力机的智能化水平,对大型粉末成型压机及其他制造装备的监控与服务都具有一定的实际参考价值。
[Abstract]:Powder forming machine is one of the important equipment in powder metallurgy. With the rapid development of powder metallurgy industry in China, the low degree of intelligence of powder forming machine has become an important reason to restrict its development. In order to improve the intelligence of powder forming equipment, a system is urgently needed to realize the remote monitoring and service of the equipment, to monitor the running state of the equipment online, to detect faults in time and to provide remote service. Taking HPP 8500 powder forming machine as the research object, the remote monitoring and service unit of large powder forming equipment is developed in this paper. In this paper, the research status of remote monitoring, mould adjustment and down impact springback device of powder forming machine is analyzed, and the overall design of remote monitoring and service unit of large powder forming equipment is carried out. Based on STM32 microcontroller, the field monitoring front end of lower computer is developed. The monitoring front end can obtain machine parameters, pressing parameters, running parameters of powder forming machine and transmit them to remote service platform through 3G communication mode. The remote service platform of the host computer is developed with C #. The whole system realizes the functions of remote auxiliary mold adjustment, electronic control and springback, remote state monitoring, remote control and so on. On the basis of remote monitoring and service unit, aiming at the difficult problem of mould adjustment encountered in powder forming equipment, this paper puts forward an adjustment algorithm based on the combination of optimization method and fuzzy control. In order to solve the problem of product cracking, an electrically controlled down-impact springback device is designed. Finally, the control method and electronic springback device are verified on HPP8500 powder forming machine. The results show that the method can effectively improve the efficiency of mould adjustment, reduce the difficulty of mould adjustment, and improve the qualified rate of the product. The research and design of remote monitoring and service unit has been applied in powder forming machine, and the expected goal of remote monitoring and service of HPP8500 powder forming machine has been realized, and the intelligence level of traditional mechanical powder forming press has been improved. It has certain reference value for monitoring and service of large powder forming press and other manufacturing equipment.
