The metal band sawing machine horizontal band saw rotates clockwise by pressing the stop (stop) button, the oil pump motor works, the gear pump works, the oil enters the pipeline through the filter, and the relief valve is adjusted to make the working pressure of the system meet the requirements. On the contrary, the button is pressed inward, and all the motors stop working. The workpiece clamping press the clamping button, the solenoid valve works, the hydraulic oil into the left side of the clamping cylinder, the right side of the hydraulic oil back to the tank, the left clamp to the workpiece clamping.
Saw machine saw beam down according to the work of the clamp, hydraulic oil through the solenoid valve into the lifting cylinder rod cavity; Rod – less hydraulic oil through the solenoid valve, one-way speed control valve back to the tank. Saw beam quickly down press the down button, the hydraulic pressure through the solenoid valve work, oil into the lifting cylinder rod chamber, no rod chamber oil through the solenoid valve back to the tank. Saw beam rise press the rise button, hydraulic oil through the solenoid valve into the lifting cylinder rod-free chamber; The rod chamber oil returns to the tank through the solenoid valve. Workpiece release press clamp loose button, hydraulic oil through the solenoid valve into the right side of the clamping cylinder; The left hydraulic oil can go back to the tank through the solenoid valve, and the left jaw moves to the left to loosen the workpiece.
The analog input and output module of the system makes the MONITORING OF the sawing process of a wide range of significance, for example: the sawing machine can adjust the sawing speed adaptively as long as the feedback of the blade deformation is increased. Speed and position control of the sawing process can be optimized by adding servo valves. The management function of the system makes the management of materials and workpieces more convenient. The Chinese interface and real-time graphical display of the system make the operation more friendly and intuitive.
