[CN201811632543.X] Scrap shear cylinder stroke fuzzy control system and method
[CN201811632543.X] Scrap steel shearing machine shearing cylinder stroke fuzzy control system and method Title: Scrap steel shearing machine shearing cylinder stroke fuzzy control system and method Application number: CN201811632543.X Applicant: Jiangsu Huahong Technology Co., Ltd. Application date: 2018-12-29 Patent type: the fuzzy control system and method for the stroke of the shearing oil cylinder of the scrap steel shearing machine include a first displacement encoder installed on the pressing oil cylinder, a second displacement encoder installed on the shearing oil cylinder, and a pressure transmitter and a controller installed on the hydraulic system of the scrap steel shearing machine. The controller reads the real-time position of the pressing oil cylinder and the pressure data of the hydraulic system when the shearing material is pushed to the set pushing length and the pressing oil cylinder starts the pressing action, analyze and calculate the deformation variable coefficient of the sheared material through the change speed of the position data and pressure data, the position data and pressure data when the pressing cylinder finally stops, and simulate the real-time height of the sheared material according to the fuzzy control algorithm based on the position data when the pressing cylinder finally stops, the real-time position and deformation variable coefficient of the shearing cylinder and the set pushing forward length, based on the real-time height of the material to be cut and the total stroke of the shear cylinder, the position of the shear cylinder to be returned is automatically adjusted.
