Abstract
The present invention proposes the finishing method of a kind of plastic spraying layer, uses the corundum abrasive pastes of proportioning to be voluntarily polished, and surface roughness reaches Ra0.8；Finally using toothpaste to repair polishing light cavity surface, surface roughness can reach Ra0.4.Toothpaste soft granules, fine uniform, thinner than corundum abrasive pastes particle, polishing effect can be improved further.After mould cavity surface spraying fluorine 46 plastics; hardness is the lowest; the fine particle of corundum abrasive pastes can be retained in coating; finally use toothpaste as polishing medium; raising surface roughness can be polished; can also play the effect of cleaning coating, practical effect is the best, has reached mold surface roughness requirement.
Description
Technical field
The present invention relates to a kind of die face painted plastic coating the method being polished, belong to mechanical processing technique skill
Art field, relates to the super-fine processing process of piece surface.
Background technology
In modern mechanical manufacturing engineering, in order to meet performance and application, the roughness for piece surface proposes more
High requirement, but it is limited to the factor of the aspects such as design of part, material, manufacturing process and process, often difficult
To reach preferable surface roughness requirements.
The head of torpedo needs to vulcanize one layer of rubber, to meet its sound translative performance parameter, but its head profile and sulfuration
The contact area of mould is big, and absorption affinity is very big, and the demoulding for convenience can improve again sulfidised surfaces quality simultaneously, sulfuration
The roughness of die face must reach more than Ra0.4.The profile of steel mould is relatively inaccessible to roughness requirements, steel
Mould is extremely hard to separate with the sound transmitting rubber on thunder head.The vulcanizing mold of integral plastics can reach roughness requirements, but
It is that the intensity of mould can not meet again use requirement.
Summary of the invention
For solving the problem that prior art exists, meeting the requirement of intensity and roughness, the present invention proposes a kind of plastics
The finishing method of sprayed coating, uses the mode of plastic spraying.
Plastic spraying is the coat at one layer of plastics of metal parts surface spraying so that it is obtain each of existing metal itself
Item feature, such as mechanical property and electric property etc.；Have again the special performance that plastics are had, as corrosion-resistant, wear-resisting,
Self lubricity, high-insulativity, be a kind of novel technological method being improved surface roughness by polishing coat.
The technical scheme is that
The finishing method of described a kind of plastic spraying layer, it is characterised in that: comprise the following steps:
Step 1: by mould cavity surface through lathe operation machine-shaping, then grind through repairing, polish so that mould cavity surface table
Surface roughness reaches Ra1.6；
Step 2: use flame spraying in mould cavity surface even application " fluoro-46 "；Described flame spraying is: use
The flame molten plastic powder " fluoro-46 " of plastic spray gun, is injected into preheating 120 DEG C～the mould cavity surface of 150 DEG C,
Form certain thickness plastic spraying layer；
Step 3: use oilstone repair grind, polishing plastic sprayed coating so that plastic spraying layer surface roughness reaches Ra3.2；
Step 4: the mould cavity surface after using corundum abrasive pastes to polish step 3 is repaiied and ground, polishes so that type
Face, chamber surface roughness reaches Ra0.8, and is cleaned up by mould cavity surface；Described corundum abrasive pastes grain size number is W5,
Its composition includes micro mist, mixing fat, oleic acid, and micro mist, mixing fat, the mass percent of oleic acid are 40:32:28；Just
Beautiful abrasive pastes also include kerosene, kerosene quality be not more than micro mist, mixing fat, the 5% of oleic acid mixing gross mass；
Step 5: use toothpaste to add proper amount of clear water and carry out as polishing medium, the mould cavity surface after step 4 is polished
Repair polishing light so that cavity surface roughness reaches Ra0.4.
Beneficial effect
The plastic coating that the present invention proposes is repaiied and is ground polishing process method, uses the corundum abrasive pastes of proportioning to be voluntarily polished,
Surface roughness reaches Ra0.8；Finally using toothpaste to repair polishing light cavity surface, surface roughness can reach Ra0.4,
Toothpaste soft granules, fine uniform, thinner than corundum abrasive pastes particle, polishing effect can be improved further.Mould
After cavity surface sprays fluoro-46 plastics, hardness is the lowest, and the fine particle of corundum abrasive pastes can be retained in coating, finally
Use toothpaste as polishing medium, raising surface roughness can be polished, additionally it is possible to play the effect of cleaning coating, real
Border using effect is the best, has reached mold surface roughness requirement.
Detailed description of the invention
Below in conjunction with specific embodiment the present invention described:
The present embodiment processing Torpedo head mould tool, it is desirable to the roughness of sulfurizing mould profile must reach more than Ra0.4,
Concrete method step is:
Step 1: by mould cavity surface through lathe operation machine-shaping, then grind through repairing, polish so that mould cavity surface table
Surface roughness reaches Ra1.6；
Step 2: use flame spraying in mould cavity surface even application " fluoro-46 "；Described flame spraying is: use
The flame molten plastic powder " fluoro-46 " of plastic spray gun, is injected into preheating 120 DEG C～the mould cavity surface of 150 DEG C,
Form certain thickness plastic spraying layer；
Step 3: use oilstone repair grind, polishing plastic sprayed coating so that plastic spraying layer surface roughness reaches Ra3.2；
Step 4: the mould cavity surface after using corundum abrasive pastes to polish step 3 is repaiied and ground, polishes so that type
Face, chamber surface roughness reaches Ra0.8, and is cleaned up by mould cavity surface；Described corundum abrasive pastes grain size number is W5,
Its composition includes micro mist, mixing fat, oleic acid, and micro mist, mixing fat, the mass percent of oleic acid are 40:32:28；Just
Beautiful abrasive pastes also include kerosene, kerosene quality be not more than micro mist, mixing fat, the 5% of oleic acid mixing gross mass；
Step 5: use toothpaste to add proper amount of clear water and carry out as polishing medium, the mould cavity surface after step 4 is polished
Repair polishing light so that cavity surface roughness reaches Ra0.4.
