Abstract
A bottle for fire extinguisher is made up of 30CrMo steel pipe through clamping the steel pipe on machine-tool, heating its one end to 870-930 deg.C, rotating while squeezing the heated end to close it, heating its open end to 870-930 deg.C, squeezing the heated end to form a bottle neck, heating the pipe to 890-940 deg.C, putting it in mould, and aerating N2 to 9.5-10 MPa. Its advantage is high rate of finished products (more than 95%).
Description
Technical field: the present invention relates to a kind of fire extinguisher bottle and manufacture method thereof.
Background technology: the material of present carbon dioxide extinguisher bottle is 45
#Steel is because 45
#The Tensile strength of steel is lower, so the bottle wall thickness must make thicklyer, and the weight of bottle is also corresponding heavier, is not easy to use in the fire fighting process.Bottle is a roll forming in addition, and the yield rate of manufacture process is low.
Summary of the invention: for the fire extinguisher bottle body weight that overcomes prior art and the low defective of yield rate of manufacture process, provide a kind of bottle lighter fire extinguisher bottle, the present invention also provides a kind of manufacture method of fire extinguisher bottle.The present invention is achieved by following proposal: a kind of fire extinguisher bottle and manufacture method thereof, the material of the bottle of fire extinguisher bottle is 30CrMo.The present invention also provides the manufacture method of this fire extinguisher bottle.It is finished as follows: one, will be clipped on the chuck 2 of lathe as an end of the steel pipe 1 of blank, the other end of steel pipe 1 is heated to 870 ℃～930 ℃, then in rotation steel pipe 1, push the end of steel pipe 1 heating forward, make this end sealing with mould 3; Two, by hydraulic test 4 blind end of steel pipe 1 is squeezed into spill; Three, the blind end with steel pipe 1 is clipped on the chuck 6 of lathe, and the openend of steel pipe 1 is heated to 870 ℃～930 ℃, then in rotation steel pipe 1, pushes the end of the fire end of steel pipe 1, the bottleneck that this end formation is narrowed forward with mould 7; Four, steel pipe 1 integral body is heated to 890 ℃～940 ℃, heating back steel pipe 1 is put into mold 5, the shape and size of mold 5 inner chambers with make finished product after the profile and the size of fire extinguisher bottle of the present invention close, between the inner surface of the outer surface of steel pipe 1 and mold 5 gapped 8, with gas plug 9 openend of steel pipe 1 is blocked then, reach 9.5MPa～10MPa by the air flue in the gas plug 9 10 inflated with nitrogen to pressure in the steel pipe 1 in steel pipe 1, keep 3 to 5 seconds of this pressure; Five, steel pipe 1 is cooled off naturally, then the openend of steel pipe 1 is loaded onto bottle neck.Fire extinguisher bottle of the present invention is promptly made and is finished.Because the tensile strength of 30 CrMo is greater than 45
#Steel; even do very thinly so adopt the fire extinguisher bottle wall thickness of 30 CrMo materials; also can satisfy the pressure requirement of fire extinguisher bottle; because so the thick very thin bottle of fire extinguisher bottle body wall is lighter; people use the present invention not feel heavy in the disaster relief process of putting out the fire; physical demands is less, and the fire extinguishing that can bring into play fire extinguisher better is used for protecting public, private property.Simple, the easy row of the manufacture method of fire extinguisher bottle of the present invention, reliable, and yield rate can reach more than 95%.
Description of drawings: Fig. 1 is the schematic diagram of fire extinguisher bottle step of manufacturing one of the present invention, and Fig. 2 is the schematic diagram of step 2, and Fig. 3 is the schematic diagram of step 3, and Fig. 4 is the schematic diagram of step 4.
The specific embodiment one: specify the present invention below in conjunction with Fig. 1 to Fig. 4.It is steel pipe 1 manufacturing of 30 CrMo that the fire extinguisher bottle adopts material, its manufacture method realizes as follows: one, will be clipped on the chuck 2 of lathe as an end of the steel pipe 1 of blank, the other end of steel pipe 1 is heated to 921 ℃～930 ℃, then in rotation steel pipe 1, push the end of steel pipe 1 heating forward with mould 3, make this end sealing; Two, by hydraulic test 4 blind end of steel pipe 1 is squeezed into spill; Three, the blind end with steel pipe 1 is clipped on the chuck 6 of lathe, and the openend of steel pipe 1 is heated to 921 ℃～930 ℃, then in rotation steel pipe 1, pushes the end of the fire end of steel pipe 1, the bottleneck that this end formation is narrowed forward with mould 7; Four, steel pipe 1 integral body is heated to 931 ℃～940 ℃, heating back steel pipe 1 is put into mold 5, the shape and size of mold 5 inner chambers with make finished product after the profile and the size of fire extinguisher bottle of the present invention close, between the inner surface of the outer surface of steel pipe 1 and mold 5 gapped 8, with gas plug 9 openend of steel pipe 1 is blocked then, reach 9.5MPa～10MPa by the air flue in the gas plug 9 10 inflated with nitrogen to pressure in the steel pipe 1 in steel pipe 1, keep 3 to 5 seconds of this pressure; Five, steel pipe 1 is cooled off naturally, then the openend of steel pipe 1 is loaded onto bottle neck.
The specific embodiment two: the difference of present embodiment and embodiment one is, the other end of steel pipe 1 is heated to 901 ℃～920 ℃ in step of manufacturing one, the openend of steel pipe 1 is heated to 901 ℃～920 ℃ in step 3, steel pipe 1 integral body is heated to 921 ℃～930 ℃ in step 4, and other step is identical with embodiment one.
The specific embodiment three: the difference of present embodiment and embodiment one is, the other end of steel pipe 1 is heated to 870 ℃～900 ℃ in step of manufacturing one, the openend of steel pipe 1 is heated to 870 ℃～900 ℃ in step 3, steel pipe 1 integral body is heated to 890 ℃～920 ℃ in step 4, and other step is identical with embodiment one.
The specific embodiment four: the difference of present embodiment and embodiment one is, the other end of steel pipe 1 is heated to 890 ℃ in step of manufacturing one, the openend of steel pipe 1 is heated to 890 ℃ in step 3, steel pipe 1 integral body is heated to 900 ℃ in step 4, steel pipe 1 internal pressure reaches 10MPa, and other step is identical with embodiment one.
