摘要
为克服普通剪板机加工精度不高,人工操作繁琐、容易出错,能耗大,效率低的不足,提出了剪板机升级为自动控制的实现方案:以PLC可编程控制系统为核心,实现多台电机的同步协调运转;再经过变频调速器控制喂料电机,实现频繁的启动、制动及精确定长。在喂料电机及自动定长单元设计中,提出了Pang-Pang控制与谨慎控制相结合的设计思路,兼顾了生产效率和定长精度两者的需求。经实验室模拟调试,系统的控制功能及控制精度达到了设计要求。该剪板机具有自动化程度高、定长精确、能耗低、喂料电机能适应频繁的启动、制动等优点。
To overcome the deficiencies of current plate shearing machine, which are the bad machining precision, complex artificial operation, easy errors, energy-wasting and inefficient, this paper puts forward such a realization scheme for the plate shearing machine to update it to automatic controlling, which is to take PLC programmable control system as its core to realize the synchronous operation coordinately with multi electric machinery. Then, frequent starting, braking and accurate fixing length will be realized through the controlling of the feeding motor by frequency converter. In the modular design of the feeding motor and automatic fixing length, put forward a design idea of integrating Pang-Pang control with conservative control to take both the productivity and accurate length-fixing into consideration. After analogue debugging in laboratory, both the control function and the control precision of the system meet design requirements. Such plate shearing machine enhances production efficiency and cutting quality of the plates with its advantages of high automation, accurate length fixing, lower energy-wasting, and also the frequent starting and braking of the feeding motor.
