Embodiment Construction

[0015] The contents represented by the part numbers marked in the attached drawings are as follows: 1. Extruder 2. Distributing hole 3. Upper die 4. Welding chamber 5. Lower die 6. Air cooling ring 7. Air outlet 8. Fan 9. Working belt of lower die 10. Working belt of upper die 11 die hole 12 shunt bridge

[0016] The first embodiment is to make a diameter of 76 mm sprinkler pipe. In this example, magnesium alloy rods with a diameter of 110 mm are selected, and an 800-ton extrusion machine is used, and the shift production is expected to be 3 tons of formed pipes. The structure and basic size of the forming die are the same as the extrusion dies for the corresponding aluminum alloy sprinkler irrigation pipes, except that the shunt bridge, welding chamber, working belt and die hole gap of the die are changed; in addition, the extrusion pipe is added to the equipment Air-cooled ring for cooling. Such as figure 1 -5, the specific content is as follows.

[0017] In this example...

Abstract

The invented magnesium alloy thin-wall anti-corrosion spray irrigation pipe is one made up by using magnesium alloy as raw material with thin-wall and making it undergo the process of anti-corrosion treatment. Said invention adopts the following measures: changing local size of extruding die, increasing thickness of flow distribution bridge and axial size of welding chamber, reducing gap of die holes and width of working bant, adding air-cooling ring and making surface anti-corrosion treatment so as to obtain the invented spray irrigation pipe.

Description

technical field [0001] The invention belongs to sprinkler irrigation equipment, and mainly relates to a manufacturing method of sprinkler irrigation pipes. Background technique [0002] The known sprinkler irrigation equipment widely uses aluminum pipes, and various aluminum and aluminum alloy sprinkler irrigation pipelines constitute the main part of the sprinkler irrigation equipment, and produce good results in use. Magnesium alloy, which is about 20% lighter than aluminum alloy, has also been reported as sprinkler irrigation pipe, and it can indeed further reduce the cost of equipment, but it has not been used in practice, and its anti-corrosion and further optimized processing methods have not yet been seen. public. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a technical scheme for implementation of the magnesium alloy thin-walled anti-corrosion sprinkler irrigation pipe. [0004] The content of the te...
