The hydraulic oil on the sawing machine should be fully added, and the sliding and rotating parts should be coated with a layer of oil.
Install the saw blade on the metal band sawing machine horizontal band saw, adjust the tightening device (turn the left handle of the saw frame) to make the band saw blade tighten to an appropriate degree, and adjust the travel switch contact to just touch the block iron and be in the open state.
Add enough coolant to the cooling water tank of the sawing machine.
After the above preparations, connect the power supply, the band saw machine itself must be grounded reliably, turn on the power switch (on the electrical control box), and start the sawing machine trial. According to the sign of the saw machine rotation correction wiring, while listening to its sound is normal. In the process of operation, the saw frame automatically drops, so that the saw belt falls below the table 0.5~1mm, the limit opening moment meets the bump block automatically rises, when the height of the limit position is automatically stopped, continuous experiments for three times. During operation, the adjusting tension device is in a relaxed state, so that the travel switch contact leaves the collision block to power off and shut down, and the experiment is carried out for three consecutive times.
Check the lifting and lowering cylinder devices of the band saw machine, and check the lifting and falling of the saw bow, whether it is reliable and flexible. Check the reported clamp mouth device, check whether the clamping is reliable, flexible release.
Adjust the speed regulating knob of the sawing machine to the 1st gear (low speed) and then to the 2nd gear (high speed). Repeat the experiment three times. When the power switch of the main motor of the sawing machine is turned on, the water pump will start at the same time, and the cooling system will operate normally. Adjust valve to check coolant flow.
After the above preparation work, the loading clamp is locked, and the test cutting is carried out.
