Sawing machine blanking, the length of general leave how much processing allowance?
Generally the length of unilateral 2-5mm, the greater the diameter, processing allowance should be appropriate to put a little more, because the cutting time, the cutting surface is not necessarily perpendicular to the axis, the raw material diameter is an integer (80,90100) Do not drop the material to a diameter of 97, should be 100 (to be laughed at), pipe material is generally diameter + wall thickness.Sawing machine is a metal cutting equipment, the machining accuracy is generally not high, is a rough machine tool, mainly for the task of blanking.
Check the lifting and lowering cylinder device, check the bow bow lift and fall, is reliable and flexible.Check the clamping and loosening the cylinder device, check whether the clamping is reliable, and relax the flexibility.Adjust the speed control knob, adjust to the 1 gear (low speed), then speed up to the 2 gear (high speed) operation, repeated experiments three times.After the main motor power switch is switched on, the water pump starts at the same time and the cooling system works normally. Adjust the valve and check if the coolant is flowing.After the above preparation work, the loading, clamping, locking, and trial sawing.
Installation and test machine of saw machine:The hydraulic oil on the saw machine should be added enough to apply a layer of oil to the sliding and turning parts.The band sawing machine is equipped with a saw belt to adjust the tensioning device (to rotate the left handle of the saw frame) so that the saw band is tightened up to a suitable level, and the switch is adjusted at the same time. The contact is just touching the stop iron and is in the open state.Add enough coolant to the cooling water tank.Do the above preparations, connected to the power supply, grounding must be reliable, open the power switch (electrical control box), started sawing test, indicated on the label according to the rotation correction wiring, while listening to the sound is normal. During operation, the saw bow is automatically lowered, so that the saw belt falls below the worktable 0.5~1mm, the limit switch head meets the bumping block and automatically rises. When the limit position is reached, the height is stopped automatically, and the experiment is conducted three times continuously. During the operation, the adjusting tightening device is in a slack state, so that the switch of the travel switch contacts the block and shuts down the power supply, and the utility model is continuously tested for three times.
If you get on the train, it's better to go down to 20mm, and leave a larger diameter.
