The application of aluminum alloy pipe in agricultural machinery is mainly sprinkler irrigation machinery, tractors, and other agricultural machinery aluminum water tank. In agricultural irrigation, spray irrigation and drip irrigation techniques are widely used to replace traditional furrow irrigation and immersion irrigation, which can improve the utilization rate of freshwater, save labor, increase production and save water, and can adapt to a variety of complex terrain. The sprinkler irrigation unit is composed of a sprinkler irrigation machine, main road, branch pipeline, riser pipe, connecting pipe fittings, and sprinkler head. According to the average calculation, each unit needs about 600m long water pipeline and 400m long water spraying pipeline, and the pipe material accounts for 69% of the total weight of the whole unit. In these pipes, mainly welded pipes, China has a special sprinkler pipe standard (GB5896-86), but its varieties are relatively simple, the nominal outer diameter of 40~60mm a total of 14 kinds, and only two kinds of pipe lengths are 5m and 6m.
The aluminum water tank for the tractor is made of a core and aluminum fins in series. The core is connected to the plate by the cooling water pipe. The cooling water pipe is made of pure aluminum and rust-proof aluminum with good corrosion resistance. In addition, aluminum alloy pipe in grain machinery, and other agricultural machinery, as well as food storage, and processing as the windpipe, and conduit, has also been widely used.
Processing technic
The quantity of the tool:5 tools
Tool type：∅40fly-cutter, ∅12mm butt mill,∅8mm butt mill,∅2.5 drill bit, M3 screw tap
In order to avoid unnecessary material waste and processing efficiency, we choose aluminum pipe material for processing. Because the annular parts are relatively thin and the outer diameter of the parts is relatively large, it is necessary to pay attention to prevent the parts from changing in the processing process and pay attention to the cutting amount and clamping of the tool.
Use ∅40 fly-cutter,∅12mm butt mill, and ∅8mm butt mill to machine parts shape.
Use ∅a 2.5 drill bit and M3 screw tap to machine the M3 thread.
Turn the head for processing, and use ∅40 fly-cutter to machining heights of 12mm and 1mm.
