Installation and debugging of sawing machine
Installation and debugging of sawing machine
1. The hydraulic oil on the sawing machine should be added enough, and a layer of oil should be applied to the sliding and rotating parts.
2. Install the saw belt on the band saw, adjust the tensioning device (turn the left handle of the saw frame) to make the saw belt tension to an appropriate level, and adjust the travel switch contact just to touch the stopper, and it is in the open state.
3. Add enough coolant to the cooling water tank.
4. After the above preparations are done, connect the power supply, the grounding must be standard and reliable, turn on the power switch (on the electrical control box), start the saw and test the car, correct the wiring according to the rotation direction indicated on the sign, and listen to whether the sound is normal. . During the operation, let the saw bow automatically drop, so that the saw belt is lowered to 0.5~1mm lower than the worktable, and the limit switch head will automatically rise when it hits the collision block. When it reaches the limit position height, it will automatically stop, and the experiment will be carried out three times in a row. During the operation, adjust the tensioning device to be in a relaxed state, let the contact of the travel switch leave the bumper and shut down the power supply, and the experiment is performed three times in a row.
5. Check the lifting and lowering cylinder devices, check whether the saw bow is lifted and dropped, whether it is reliable and flexible.
6. Check the clamping and loosening cylinder device, check whether the clamping is reliable when clamping, and whether the loosening is flexible.
7. Adjust the speed control knob, adjust it to 1st gear (low speed) to run, then adjust the speed to 2nd gear (high speed) to run, repeat the experiment three times.
8. After the main motor power switch is turned on, the water pump will start at the same time, and the cooling system will operate normally. Debug the valve and check if the coolant is smooth.
9. After the above preparations are done, the loading is clamped and locked for trial sawing.
