Sawing machine in the daily use of the process will be some common faults, sawing machine users may wish to grasp some of the common faults that may occur and troubleshooting, so that a more in-depth understanding of the use of sawing, but also for production and processing to win more time , For enterprises to create more benefits. The following is a common sawing machine failure and troubleshooting methods:
First, band saw blade drop: The reason may be sawtooth is too loose, or the main, driven wheel is not parallel. Remedy: Adjust the saw band tensioner to maintain the proper tension of the saw band; adjust the three sets of adjustment screws behind the driven wheel so that the main and driven wheels are parallel to ensure that the saw blade is in place.
Second, the worm gear box sound abnormalities: the reason may be worm gear axial clearance is too large or two teams bearing wear is too large. Remedy: Adjust worm shaft axial clearance or replace the bearing.
Third, sawing saw frame does not rise: Need to check whether the oil pressure reaches the rated pressure, the solenoid valve is working, the upper limit switch is reset, whether the air into the air or blocked. Remedy: Oil pressure, regulating relief valve to the required pressure; check the circuit, the oil is unobstructed; check the limit trip switch; cleaning or replacement of oil filters and solenoid valves.
Fourth, sawing belt does not drop: Need to adjust the valve plugging; may be down solenoid valve does not work; check the lower limit switch is reset; check whether the back pressure is too large transfer. Remedy: Check the cleaning speed control valve; check the circuit, the oil passage is; check the limit trip switch; adjust the back pressure to achieve the required value.
Fifth, sawing sawing, sawing frame severe vibration or abnormal noise: the column may be too large gap with the sliding sleeve; or sawing material and the speed of the wrong choice; or saw with the guide block clearance is too large. Remedy: Replace the copper sleeve; re-select the saw blade speed; adjust the guide block.
Sixth, the workpiece is seriously skewed: the main reason is too large feed; serrated passivation or sub-tooth asymmetry; the distance between the two guide arm is too large; saw band has been tightened; two guide block has been tightened; Countertops, fixed vices and saw not vertical. Remedy: make the feed rate appropriate; replace the band saw blade; the distance between the two guide arms and the workpiece line; make the saw blade to maintain proper tension; tighten the two guide blocks; adjust the guide arm and the fixed vise, table vertical.
