Abstract
The invention provides a polishing method for a plastic spraying coating; a corundum abrasive paste prepared automatically is used for polish, wherein the surface roughness reaches Ra0.8; then toothpaste is used to repair and grind the polishing type cavity surface, wherein the surface roughness can reach Ra0.4. The toothpaste particles are soft, small and uniform, and thinner than the corundum abrasive paste particles, thus being capable of further improving the polishing effect. After the mold cavity surface is sprayed and coated with fluorine-46 plastic, the hardness is very low, the small particles of the corundum abrasive paste are left on the coating, finally, the toothpaste is used as a polishing medium which can polish to improve the surface roughness and also can play a role in cleaning the coating, and thereby the actual use effect is very good, and the requirement on the surface roughness of the mold is achieved.
Description
Technical field
The present invention relates to a kind of die face painted plastic coating and carry out the method for polishing, belonging to mechanical processing technique technical field, relate to the super-fine processing process of piece surface.
Background technology
In modern mechanical manufacturing engineering, in order to meet performance and application, roughness for piece surface is had higher requirement, but is limited to the factor of the aspects such as design of part, material, manufacturing process and process, is often difficult to reach desirable surface roughness requirements.
The head of torpedo needs sulfuration one deck rubber, and to meet its sound translative performance parameter, but the contact area of its head profile and sulfurizing mould is large, absorption affinity is very large, the conveniently demoulding, can improve sulfidised surfaces quality again, the roughness of sulfurizing mould profile must reach more than Ra0.4 simultaneously.The profile of steel mould is more difficult reaches roughness requirements, and steel mould and the sound transmitting rubber on thunder head are extremely difficult to be separated.The vulcanizing mold of integral plastics can reach roughness requirements, but the intensity of mould can not meet instructions for use again.
Summary of the invention
For solving prior art Problems existing, meeting the requirement of intensity and roughness, the present invention proposes a kind of finishing method of plastic spraying layer, adopt the mode of plastic spraying.
Plastic spraying is the coat at metal parts surface spraying one deck plastics, makes it obtain every feature of existing metal itself, as mechanical property and electric property etc.; Having again the special performance that plastics have, as corrosion-resistant, wear-resisting, self lubricity, high-insulativity, is a kind of novel technological method being improved surface roughness by polishing coat.
Technical scheme of the present invention is:
The finishing method of described a kind of plastic spraying layer, is characterized in that: comprise the following steps:
Step 1: by mould cavity surface through the machine-shaping of lathe operation, then grind through repairing, polishing makes mould cavity surface surface roughness reach Ra1.6;
Step 2: adopt flame spraying in mould cavity surface even application " fluoro-46 "; Described flame spraying is: with the flame melting plastic powders " fluoro-46 " of plastic spray gun, be ejected into the die surface of preheating 120 DEG C ~ 150 DEG C, form certain thickness plastic coating layer;
Step 3: adopt oilstone repair grind, polishing sprayed coating, make sprayed coating surface roughness reach Ra3.2;
Step 4: adopt corundum abrasive pastes to repair mould cavity surface to grind, polishing, makes cavity surface surface roughness reach Ra0.8, and is cleaned up by mould cavity surface; Described corundum abrasive pastes grain size number is W5, and its composition comprises micro mist, mixing fat, oleic acid, and the mass percent of micro mist, mixing fat, oleic acid is 40:32:28; Also comprise kerosene in corundum abrasive pastes, kerosene quality be not more than micro mist, mixing fat, oleic acid mixing gross mass 5%;
Step 5: adopt toothpaste to add proper amount of clear water as polishing medium, polishing light is repaiied to the mould cavity surface after step 4 polishing, makes cavity surface roughness reach Ra0.4.
Beneficial effect
The plastic coating that the present invention proposes is repaiied and is ground polishing process method, and adopt the corundum abrasive pastes of proportioning voluntarily to carry out polishing, surface roughness reaches Ra0.8; Finally adopt toothpaste to repair polishing light cavity surface, surface roughness can reach Ra0.4, toothpaste soft granules, fine uniform, thinner than corundum abrasive pastes particle, can improve polishing effect further.After fluoro-46 plastics of mould cavity surface spraying; hardness is very low; the fine particle of corundum abrasive pastes can be retained in coating; finally adopt toothpaste as polishing medium; polishing can improve surface roughness; can also play the effect of clean coating, practical effect is very good, reaches mold surface roughness requirement.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described:
The present embodiment processing Torpedo head mould tool, require that the roughness of sulfurizing mould profile must reach more than Ra0.4, concrete method step is:
Step 1: by mould cavity surface through the machine-shaping of lathe operation, then grind through repairing, polishing makes mould cavity surface surface roughness reach Ra1.6;
Step 2: adopt flame spraying in mould cavity surface even application " fluoro-46 "; Described flame spraying is: with the flame melting plastic powders " fluoro-46 " of plastic spray gun, be ejected into the die surface of preheating 120 DEG C ~ 150 DEG C, form certain thickness plastic coating layer;
Step 3: adopt oilstone repair grind, polishing sprayed coating, make sprayed coating surface roughness reach Ra3.2;
Step 4: adopt corundum abrasive pastes to repair mould cavity surface to grind, polishing, makes cavity surface surface roughness reach Ra0.8, and is cleaned up by mould cavity surface; Described corundum abrasive pastes grain size number is W5, and its composition comprises micro mist, mixing fat, oleic acid, and the mass percent of micro mist, mixing fat, oleic acid is 40:32:28; Also comprise kerosene in corundum abrasive pastes, kerosene quality be not more than micro mist, mixing fat, oleic acid mixing gross mass 5%;
Step 5: adopt toothpaste to add proper amount of clear water as polishing medium, polishing light is repaiied to the mould cavity surface after step 4 polishing, makes cavity surface roughness reach Ra0.4.
