变压器上线圈打磨设备设计和控制

Design and Control of Coil Sanding Equipment for Transformer

针对变压器生产过程中,线圈在浇注完成后需要打磨时,受到空间的限制存在的工作效率低、打磨噪声大、粉尘飞溅多、变压器易受损等缺点,提出了一种新型基于PLC控制自动打磨线圈的方案。设计了线圈打磨设备机械结构的整体方案;采用西门子S7-1200系列PLC为控制核心设计了系统的总体控制模块,包括气动控制模块和电路控制模块;利用气动控制模块实现对变压器的夹紧功能,利用电路控制模块实现外部输入信号的接收和处理功能;采用伺服电机实现打磨装置的上下移动、左行和右行的功能;根据顺序动作的控制思想,设计了打磨设备的控制流程;采用Tia Portal V13软件实现打磨设备手动、回原点、单循环、自动、自行检测、报警等控制功能。应用结果表明打磨设备具有稳定性好、实用方便等特点,且可提高工厂变压器的调度管理能力。该系统能有效改善人工打磨线圈设备存在的工作效率低、打磨噪声大、粉尘飞溅、变压器易受损的状况,提高了变压器线圈的打磨效率。

According to the transformer production process, coil needs to be polished in the casting is completed, by the shortcomings of space constraints the work efficiency is low, grinding noise, dust and splash more easily damaged transformer, proposes a new PLC control scheme based on the automatic grinding coil. The overall design of the coil grinding equipment of mechanical structure; using the SIEMENS S7-1200 series PLC to control the core of overall design of the control module of the system, including the pneumatic control circuit module and a control module; the pneumatic control module to realize the clamping function of the transformer, using the circuit module to realize the receiving and processing function of the external input signal; the move, left and right for the realization of the function of the servo motor on the polishing device; According to the control theory of motion sequence, design the control process of grinding equipment; implement grinding equipment manual, back to the origin, single cycle, automatic, self detection and alarm control function using Tia Portal V13 software. The application results show that the grinding equipment has the advantages of good stability, practicability and convenience, and can improve the dispatching management ability of the plant transformer. The system can effectively improve the low efficiency, large grinding noise, dust splash and transformer damage, and improve the sanding efficiency of the artificial coil equipment.
