Analyze the hydraulic schematic diagram of sawing machine. The hydraulic system can realize three functions: the saw bow can be quickly retracted, the saw bow can be quickly driven in, and the feed motion of the saw bow (feed and lift motion) can be realized with the linear reciprocating motion of the saw bow.

Through analysis and two previous error handling, it is concluded that the reason why the tool cannot be fed appears on the feed cylinder. Then remove the feed cylinder for maintenance. Fill the lower chamber of the oil cylinder with half chamber oil, press the piston into the cylinder and slowly pressurize it. The hole in the middle of the piston rod injects oil, indicating that it is normal. Plug the hole with manual force and continue to press the piston to move towards the cylinder bottom. It is found that one of the two check valves at the piston rod emits a little oil, more and less for a while. The greater the pressure, the more oil, indicating that the upper and lower chambers of the oil cylinder collude during work progress, If the differential pressure tends to or equal to zero, of course, the normal feed cannot be carried out.

After removing the one-way valve emitting oil, it was found that a small steel ball with a diameter of 3mm was installed. After removing the small steel ball, clean the oil cylinder, reinstall it, start the hacksaw, and everything is normal.

Sawing machine is a relatively simple machine tool. Users will not require their own sawing machine to have the function of machining center. The computer-controlled sawing machine not only improves the sawing efficiency and quality for users, but also the network function of the computer, which will make the sawing more closely connected with other links of CIMS and more convenient management.

Before starting the lubrication system, oil must be added according to the requirements of the lubrication parts of the machine tool (wire brush shaft, worm gear box, driving bearing seat, worm bearing, upper and lower shafts of lifting oil cylinder, clamping screw rod on the sliding surface of movable vice). The worm gear and worm in the worm gear box are lubricated with No. 30 oil bath and injected by the oil plug hole on the upper part of the worm gear box. The box surface is equipped with an oil standard. When the saw beam is at the lowest position, the oil level should be between the upper and lower limits of the oil standard. The oil shall be changed after one month of trial use, and then every 3-6 months. An oil drain plug is set at the lower part of the worm gear box.

The saw blade drives the motor installed on the worm gear box, drives the worm and worm gear in the worm gear box through the belt pulley and triangular tape, drives the driving wheel to rotate, and then drives the saw blade around the active / passive rim for cutting rotation. The feed movement of saw blade is a hydraulic circulation system composed of lifting oil cylinder and speed regulating valve, which controls the falling speed of saw beam, so as to control the feed (stepless speed regulation) movement of saw blade. The saw brush rotates at the place where the saw blade produces chips and rotates with the direction of the saw blade. The cooling pump supplies coolant for cleaning to remove the chips on the sawtooth. The coolant is in the coolant tank on the right side of the base, which is directly driven by the water pump to supply coolant.

Press the emergency stop (stop) button, rotate clockwise, the oil pump motor works, the gear pump works, the oil enters the pipeline through the filter screen, and adjust the overflow valve to make the system working pressure meet the requirements. Conversely, press the button inward and all motors stop working. When the workpiece is clamped, press the clamping button, the solenoid valve works, the hydraulic oil enters the left of the clamping cylinder, the hydraulic oil returns to the oil tank on the right, and the left clamp is clamped to the workpiece.

When the saw beam is lowered, press the Tong, and the hydraulic oil enters the rod cavity of the lifting oil cylinder through the solenoid valve; The hydraulic oil in the rodless chamber returns to the oil tank through the solenoid valve and one-way speed regulating valve. When the saw beam drops quickly, press the drop button, the hydraulic pressure works through the solenoid valve, the oil enters the rod cavity of the lifting cylinder, and the oil without rod cavity returns to the oil tank through the solenoid valve. When the saw beam rises, press the rise button, and the hydraulic oil enters the rodless cavity of the lifting cylinder through the solenoid valve; The oil in the rod chamber returns to the oil tank through the solenoid valve. When the workpiece is released, press the clamp release button, and the hydraulic oil enters the right side of the clamping cylinder through the solenoid valve; The left hydraulic oil can return to the oil tank through the solenoid valve, the left jaw moves to the left and the workpiece is loosened.

The analog input and output module of the system makes the monitoring of the sawing process of a wide range of significance. For example, as long as the feedback of saw blade deformation is increased, the sawing speed can be adjusted adaptively. By adding servo valve, the speed and position control of sawing process can be optimized. The management function of the system makes the management of materials and workpieces more convenient. The Chinese interface and real-time graphical status display of the system make the operation more friendly and intuitive.

Spring wind is about to ring auspicious bell, we will be in the same frequency symphony resonance moment, placing a new hope.

At this moment of bidding farewell to the old and ushering in the new, Zhejiang Jinyun Hanli Saws Co., Ltd. would like to express our heartfelt thanks and best wishes to you on the arrival of the New Year in 2019.
