Description

Automobile lampshade mould body surfaces mirror polishing method
Technical field
The present invention relates to a kind of automobile lampshade mould body surfaces mirror polishing method.
Background technology
Lamp shade forming die main body surface does not generally reach minute surface requirement in the market, and detailed process generally all adopts craft sand paper echelon to enter a grade mode sanding.Which operator first selects 180 order sand paper to carry out preliminary sanding to profile, then selects 240 order sand paper sand thin, then adopts 360 orders, 600 orders, the sanding step by step like this of 800 order sand paper successively, finally receives light with 1200 order sand paper.The polished surface smoothness of which is poor, and fineness still cannot reach requirement.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of automobile lampshade mould body surfaces mirror polishing method improving lampshade product surface quality.
The technical solution used in the present invention is: a kind of automobile lampshade mould body surfaces mirror polishing method, comprises the steps,
Step one, first checks before polishing that die main body machining surface processes the vestige stayed;
Step 2, granularity is adopted to coordinate polishing fluid sander to process the vestige stayed at the oilstone of 400-600, polishing direction becomes 25 °-30 ° to throw back and forth with vestige direction, and then oppositely become 25 °-30 ° to throw back and forth with vestige direction, realize intersecting polishing, until can't see the vestige that machined stays;
Step 3, adopts the vestige that granularity coordinates polishing fluid polishing step 2 to stay at the oilstone of 800-1000;
Step 4, adopts 600 orders, 800 orders, 1200 order sand paper cooperation polishing fluid sandings step by step successively, finally coordinates polishing fluids to receive light with 1500 order sand paper;
Step 5, the cotton textiles flower with 100% is drawn alcohol and is cleaned die main body surface, checks polishing situation, coordinates polishing fluid along the direction polishing of die main body straight flange again as also having darker tool marks with 1500 order sand paper;
Step 6, adopt be provided with wool bat High Rotation Speed polishing machine be stained with grain size number be W3 abrasive pastes to die main body surface glazing;
Step 7, then with wool sheet be stained with grain size number be W1 abrasive pastes to die main body surface glazing;
First throw mouth R angle, body surfaces limit and corner portions when step 2 and step 3 polishing, then throw vertical part, finally throw plane; When throwing R angle or corner portions, first oilstone is worn into and throw again with R angle or corner matching form.
First oilstone is worn into throw again with R angle or corner matching form and refer to, first intercept one section of sand paper and be attached to R angle or corner, then by oilstone facing to sand paper mill, until after oilstone and R angle or corner matching form, then sand paper of tearing, throw with oilstone.
In step 4 and step 5 when polishing R angle or corner, sand paper is pasted onto polishing again on rubber blanket.
The invention has the beneficial effects as follows: a kind of automobile lampshade mould of the present invention body surfaces mirror polishing method, the progressive mode of first rough polishing fine polishing is again adopted to carry out polishing, automobile lampshade mould body surfaces minute surface is allowed to reach minute surface requirement, for the lifting of downstream lampshade quality provides solid condition.
Detailed description of the invention
Be below present pre-ferred embodiments, but therefore do not limit protection scope of the present invention.
A kind of automobile lampshade mould of the present invention body surfaces mirror polishing method, comprises the steps,
Step one, first checks before polishing that die main body machining surface processes the vestige stayed;
Step 2, adopts granularity to coordinate polishing fluid sander to process the vestige stayed at the oilstone of 400-600, adopts during oilstone polishing and needs to coordinate polishing fluid polishing together, avoid dry throwing, mainly prevent die surface to produce heat, prevent orange peel phenomenon from producing.Polishing direction becomes 25 °-30 ° to throw back and forth with vestige direction, and then oppositely becomes 25 °-30 ° to throw back and forth with vestige direction, realizes intersecting polishing, until can't see the vestige that machined stays; What is it about the intersection polishing that now for example bright place of the present invention refers to, polishing direction becomes 25 °-30 ° to throw back and forth with vestige direction for the first time, namely with trace line clockwise (or counterclockwise) become 25 °-30 ° to throw back and forth, be upper right and lower-left is thrown back and forth; After having thrown, second time is when throwing, more oppositely becomes 25 °-30 ° to throw back and forth with vestige direction to refer to that counterclockwise with trace line (or clockwise) becomes 25 °-30 ° to throw back and forth, be upper left and bottom right and throw back and forth; The benefit of intersection polishing can effectively all remove former vestige and not leave new vestige exactly.The angle simultaneously chosen the main cause of 25 °-30 ° is, under this angle, polishor can see former vestige track smoothly, throws also more smoothly simultaneously.
Step 3, adopts the vestige that granularity coordinates polishing fluid polishing step 2 to stay at the oilstone of 800-1000; Coordinate polishing fluid, the same with object in step 2.
Step 4, adopts 600 orders, 800 orders, 1200 order sand paper cooperation polishing fluid sandings step by step successively, finally coordinates polishing fluids to receive light with 1500 order sand paper; Coordinate polishing fluid, the same with object in step 2.
Step 5, the cotton textiles flower with 100% is drawn alcohol and is cleaned die main body surface, checks polishing situation, coordinates polishing fluid along the direction polishing of die main body straight flange again as also having darker tool marks with 1500 order sand paper; What die main body straight flange direction was finished to is exactly after polishing, and the trickle lines in die main body surface can be made more consistent.
Step 6, adopt be provided with wool bat High Rotation Speed polishing machine be stained with grain size number be W3 abrasive pastes to die main body surface glazing;
Step 7, then with wool sheet be stained with grain size number be W1 abrasive pastes to die main body surface glazing;
First throw mouth R angle, body surfaces limit and corner portions when step 2 and step 3 polishing, then throw vertical part, finally throw plane; When throwing R angle or corner portions, first oilstone is worn into and throw again with R angle or corner matching form.During polishing, order throws R angle and corner portions, the vertically peaceful face of part, such as, when having boss.If not polishing like this, such as last throwing is put at R angle and corner portions, after easily causing R angle and corner portions polishing, impact to plane or face directly, must again to plane or face polishing directly, wearing and tearing causing die main body unnecessary and increase polishing time.
First oilstone is worn into throw again with R angle or corner matching form and refer to, first intercept one section of sand paper and be attached to R angle or corner, then by oilstone facing to sand paper mill, until after oilstone and R angle or corner matching form, then sand paper of tearing, throw with oilstone.The shape of oilstone and R angle or corner matching form, be so more conducive to the polishing effect of R angle or corner, if directly thrown with a bit of oilstone, oilstone edge can cause R angle or corner to produce darker vestige, runs counter to desire.
In step 4 and step 5 when polishing R angle or corner, sand paper is pasted onto polishing again on rubber blanket, because sand paper is thinner, and need to carry out polishing to each place of die main body, especially not the place of plane, there is rubber blanket, can be more tight, stressed also more even when sand paper and die main body are fitted.
According to above-mentioned step polishing, automobile lampshade mould body surfaces minute surface can be allowed to reach minute surface requirement.
