Abstract
A rotary seal coupler belongs to the technical field of sealing. It is used to connect the fixed end (static body) and the rotating body (dynamic body) to prevent medium leakage, prolong service life and reduce production cost. I.e. for the mechanical sealing coupling between the fixed end and the rotating body.
The sealing gasket 4 in the shape of a discus is made of F-4 or filled with F4 and the like, can axially move along the static body 6 under the action of the spring 11, and has the function of axial and radial automatic compensation together with the compression deformation and the heating deformation. A plurality of seals are formed by the positioning nut 2, the aligning pad 3, the sealing gasket 4, the moving body 1 and the movable flange 5.
The moving body 1 and the static body 6 can be fixed respectively, the bearing capacity, rigidity and concentricity of the connector are improved, and the size of an inlet and an outlet is not limited.
Description
The present invention relates to utilize iron-manganese-aluminum alloy to produce and resemble the method for the thin-walled fine cast of Fe-Mn of the complicated shape of a golf ball metallic rod class and became uneven.
Resemble the fine cast of Fe-Mn of a metallic rod class of golf clubs in the prior art, using nickel-chromium (Ni-Cr) mostly is stainless steel etc.In addition, also just trying out high tenacity and mechanical strength height, corrosion resistance is superior, and the iron-manganese-aluminum alloy of wear resistance is arranged.
Yet, with the nickel-chromium (Ni-Cr) of above-mentioned prior art is the metallic rod head of the golf clubs made of stainless steel, the drumming surface strength deficiency that hits golf ball is arranged, the possibility that damage aforementioned metal bar head is arranged, because the shock absorption when hitting is poor, problems such as it is big to have percussive sounds, and proportion is also big.In addition, about iron-manganese-aluminum alloy aspect, because various researchs are arranged, though can know a little aforesaid advantages, still have that rates of thermal expansion is big, thermal conductivity is low, and when this alloy of melting, easily oxidation, the hindering factor on the casting process that has fragility to organize partial crystallization etc. is formed in crystallization, and it is still indeterminate that the cooperation of the technical material of this alloy casting, the management of casting process and the heat treatment of foundry goods etc. can influences the characteristic aspect of goods, and the not problem of establishment is still arranged on foundry engieering.
Because the problems referred to above, the objective of the invention is to propose to use than nickel-chromium (Ni-Cr) is the inexpensive iron-manganese of stainless cast steel part-aluminium (Fe-Mn-Al) alloy, and produces the casting method of complicated shape and the uneven thin section castings of foundry goods section thickness under the advantageous characteristic that does not undermine iron-manganese-aluminum alloy.
The casting method of iron-manganese of the present invention-aluminum alloy is to consist of carbon (C) 0.5～2.0 weight %, manganese (Mn) 25～36 weight %, aluminium (Al) 5～10 weight %, silicon (Si) 0.5～1.5 weight %, molybdenum (Mo) 0.5～1.5 weight %, on the casting process of the precision casting of the iron-manganese-aluminum alloy of the residual amount of iron (Fe), first rapid heating is fused the above-mentioned alloy to 1400～1420 ℃, inject and be preheated to 1300～1320 ℃ Tao Monei, casting assembly with the plural number of this Tao Mo gained welds in the TIG mode, welding current is 40～60 amperes, the foundry goods that has welded is done down solid melt processed 1～2 hours at 1030～1050 ℃, again through 1～2 hour ageing treatment of 450～550 ℃; The feature of above-mentioned Tao Mo is that thickness is about 5mm, and wet strength is that 350psi, bond strength are that 460psi and air penetrability are 6.5 * 10

2.aq Tao Mo, heating earlier remains on 1300～1320 ℃.Manage carbon (C) 0.5～2.0 weight %, manganese (Mn) 25～36 weight %, aluminium (Al) 5～10 weight %, silicon (Si) 0.5～1.5 weight %, molybdenum (Mo) 0.5～1.5 weight %, the residual amount of iron (Fe) of consisting of that make in addition, to cooperate alloy raw material.
When this alloy raw material of heating melting, prevent fused raw material because oxidation generates slag film (folder film), and be cast into shortcomings such as microstructure segregation that Tao Monei just causing or be full of cracks in the way of condensation, for making aforementioned fused raw material molten steel can flow in the aforementioned mold well, when melting arrives 1200 ℃, utilize rapidly mode of heating with about 20-25 minute heating fusion alloy to 1400～1420 ℃, when arriving 1400-1420 ℃, be cast into aforementioned Tao Monei immediately.
When the bottom periphery that splice the main body portion 3 and the bottom 5 of welding cooled and solidified, weld with adding material mode (no-file) not, if welding current is too little or too big, then can cause and to weld or to be soldered near hot tearing, this is the different events with the body material of scolder, so welding current is controlled at 40～60 amperes, does not add material with the TIG welding manner and weld.
When the metallic rod after the welding 1 is heat-treated, as Fig. 5 and shown in Figure 6, utilize metallic rod that the heat treated nitrogen type of cooling of vacuum furnace heat-treats 1, its surperficial oxide thickness is thin, and Rockwell Hardness (HRC) is HRC32～36 when vacuum furnace, when continuous oven HRC28～32, hardness is suitable, but toughness intensity and mechanical strength variation, therefore, as shown in Figure 4, put into the high temperature continuous oven that temperature is maintained at 1030～1050 ℃ and did constant temperature heat treatment 1～2 hour, and utilize shrend or oil quenching mode to give chilling, carry out solid melt processed, so that Rockwell Hardness becomes HRC8～12.
Thereafter, after carrying out processing operations such as hue angle, fraising, impose 450～550 ℃ 1～2 hour ageing treatment again, Rockwell Hardness can become HRC28～36.
The metallic rod of handling through this timeliness 1 can be utilized sandblast or bead ejection operation, removes the oxide layer of remained on surface, is coated with coating to make dry thickness of filming become 3～5 μ m, and carries out baking vanish and handle.
And the composition of aforementioned iron-manganese-aluminum alloy, with carbon (C) 0.5～2.0 weight %, manganese (Mn) 32～36 weight %, aluminium (Al) 6～8 weight %, silicon (Si) 0.5～1.5 weight %.Molybdenum (Mo) 0.5～1.5 weight %, the residual amount of iron (Fe) is advisable.
Below aforesaid Tao Mo is given explanation.
Aforementioned Tao Mo for the molten steel of the alloy raw material that makes aforementioned fusion does not generate slag, also prevents the crystalline structure segregation, makes Tao Mo can keep high temperature, need have can be high temperature resistant refractory nature.In addition, since the condensation systolic pressure that is generated in the low cooling of thermal expansion coefficient is big, thermal conductivity is low iron-manganese-aluminum alloy make generate be full of cracks or crack etc. on the metallic rod 1 before, this Tao Mo is had collapse diffusing character voluntarily.Therefore, the proportioning of this Tao Mo is as follows:
First layer slurry: 325mesh zirconium powder+25%SO
2Silicon acid glue
Facing sand: 100mesh zircon sand
Second layer slurry: 200mesh Malaysia powder+25%SO
2Silicon acid glue+4% plumbago
Floor sand: 0.25～0.5m/m burns mill soil
The 3rd layer of slurry: 200mesh Malaysia powder+25%SO
2Silicon acid glue+4% plumbago
Floor sand: 0.25～0.5m/m burns mill soil
The 4th layer of slurry: 200mesh Malaysia powder+25%SiO
2Silicon acid glue+6% plumbago
Floor sand: 0.5～1.0m/m burns mill soil
The castability that the shell mould that is formed by above 5 layers fireproof slurry sand dipping lining contacts with molten alloy is best.
The effect of the foregoing description is to consist of carbon (C) 0.5～2.0 weight %, manganese (Mn) 25～36 weight %, aluminium (Al) 5～10 weight %, silicon (Si) 0.5～1.5 weight %, molybdenum (Mo) 0.5～1.5 weight %, the residual amount of iron (Fe), manage the alloy material of cooperation, through being dissolved to 1400～1420 ℃ fast, inject and be preheated to 1300～1320 ℃ Tao Monei, can prevent the slag that metal at high temperature generates owing to oxidation, the alloy molten steel of aforementioned fusion flows good in this Tao Monei, can prevent the segregation of crystalline structure.Therefore, make aforementioned Tao Mo thickness and be about 5mm, wet strength is 350psi, and bond strength is that 460psi and air penetrability are 6.5 * 10
