3. Product Structure and Working Principle of Type III Internal Combustion Rail Cutting Machine
Working Principle: Based on the toothless saw cutting principle, the swing mechanism is used to make the axis of the rotating sheet grinding wheel follow a certain trajectory around the axis of the rail. Oscillating back and forth, the sheet grinding wheel cuts the rail. The contact length between the rotating plane of the lamella grinding wheel and the rail section is small, thereby reducing the wear of the lamella grinding wheel and improving the utilization rate and work efficiency of the lamella grinding wheel.
Main movement: The main shaft (thin grinding wheel) is rotated by the engine through the clutch and drive belt.
. Feeding movement: The relative swing of the cutting arm and the swing arm is used, and the weight of the rail cutting machine is used to realize the feeding and cutting movement of the thin grinding wheel. The rotating surface of the thin grinding wheel of the cutting arm spindle is beside the center plane of the swing arm (rail clamping mechanism), and the cantilever is long, so the saw blade can cut to the bottom of the rail.
Basic structure:
There is rolling friction between the swing arm shaft and the sleeve, which reduces wear and extends life.
The swing arm, cutting arm and pulley are made of cast aluminum alloy structure, which is light in weight and high in strength.
The clamping mechanism has the function of preventing derailment. The rail cutting machine is placed on the rail. The center of gravity of the rail cutting machine coincides with the central axis of the rail. Even if the clamping screw is loosened, the rail cutting machine will not tilt.
The internal combustion engine base is made of split cast aluminum alloy to reduce weight.
The running mechanism is equipped with auxiliary wheels to ensure smooth operation on the ground.

4. How to use type III internal combustion rail cutting machine
First install the lamella grinding wheel and load the flakes Before installation, check whether the lamella grinding wheel has cracks, whether it is deformed by moisture, and whether both sides are straight. Uneven surfaces may cause the incision to deflect and clamp. After installing the lamellae, tighten the locking nut, but the torque should not be too large to avoid crushing the lamella grinding wheel.
. Install the rail cutting machine on the rail and pull out the positioning rod installed on the fixture. At this time, the position indicated by the end face of the positioning rod is the cutting position of the grinding wheel. Move the rail cutting machine to the preset position as needed. Cutting position. Then make the inner surface (convex surface) of the clamp close to the top surface of the rail and the lower part of the rail palate, tighten the fixing bolt, and the rail cutting machine is in working condition.
Pull the joystick with one hand to keep the rail cutting machine above the rail, while holding the other joystick with the other hand to prevent the sheet grinding wheel from hitting the rail.
After installing the rail cutting machine, pull the starting handle to start the internal combustion engine. After the internal combustion engine is started, run it at idle speed for no less than 3 seconds. Check whether all parts of the machine are normal. If there is any abnormality, stop it and eliminate it. Increase the throttle and observe whether the thin grinding wheel runs smoothly, whether it deflects or jumps, and whether all parts are normal. If any abnormality is found, the machine should be shut down to replace the grinding wheel or troubleshoot. Before cutting, adjust the throttle and damper to meet cutting needs.
When cutting, the feeding of the thin grinding wheel mainly depends on the dead weight of the rail cutting machine and the swing of the joystick. Therefore, when holding the joystick with both hands, do not exert downward force and swing the joystick rhythmically as needed.
During the cutting process, the joystick must be kept swinging back and forth and must not stop somewhere. When pinching occurs, slowly lift the lamella grinding wheel, and then continue cutting. If pinching still occurs, stop the machine to check the cause or replace the lamella grinding wheel. When re-cutting, the thin grinding wheel must completely match the original incision, otherwise, the cutting position should be changed.
During the cutting process, if the cut is tilted, the machine should be stopped to check the cause, troubleshoot or replace the thin grinding wheel, change the cutting position, and cut again.
Usually, the top of the rail is cut first, then the waist, and then the bottom until it is cut off.
When the thin grinding wheel is worn to a certain extent (the diameter of the grinding wheel is about less than 3), it may not be possible to cut the rail from one side of the rail. At this time, the grinding wheel needs to be moved to the other side to cut the rail in half until it is cut. When the diameter of the grinding wheel is less than about 10% after wear, the grinding wheel will accelerate wear due to the reduction of the linear speed of the grinding wheel. At this time, even if the rail is cut in half, the rail may not be completely cut. It is recommended to replace the thin slice grinding wheel to avoid not cutting the rail. Replacing the grinding wheel will cause the new grinding wheel to be separated from the rail. The original incision does not match.
5. Maintenance and repair of machine tools
The swing arm and the long shaft should be kept lubricated, and lubricating oil should be injected into the oil injection nozzle regularly.
After the rail cutting machine has been running for accumulated hours, the main shaft bearing should be disassembled and cleaned, and the grease should be replaced.
The swing arm and the cutting arm are connected by threaded pins, which have been adjusted before leaving the factory. When they become loose after wear, the locking nut can be loosened, the threaded pins are rotated, and the axial clearance of each part is adjusted. Make sure they can rotate with each other without axial movement, and then tighten the nut.
The tension of the belt drive is adjusted by turning the two hexagonal bolts.
, Do not throw or drop during use and transportation.
If not used for a long time, it should be placed in a ventilated, dry, and corrosive-free warehouse. The internal combustion engine should release fuel.
The thin grinding wheel should be moisture-proof, anti-collision and anti-pressure.
The recommended operating environment temperature of the machine is between -℃~℃.
It is recommended to use lead-free products with an octane number or higher. When refueling, the engine should be stopped and kept away from fire sources. Refueling should be done in an appropriate amount. After refueling, the surface of the machine should be wiped clean of residues.
Frequently check whether the lubricating oil of the machine is sufficient and whether the air filter is clean.
. Do not let the machine and tools get exposed to rain. If they are exposed to rain, dry the machine and all parts of the machine.
