Abstract
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.关键词
