Abstract
The invention discloses a kind of flange polishing process, comprise the following steps：（1）Remove flash removed：The burr of flange periphery and hole inwall is scraped off with scraper；（2）Corase grind：With 200# dry abrasive papers polish flange surface, and with wire brush polish hole inwall；（3）Fine grinding：Flange is placed on sander and polished, during polishing using 600# silicon carbide paper and open the tap on sander；（4）Fine grinding：Flange after will be finely ground is removed from sander, the sand paper on sander is replaced by after 1000# silicon carbide paper flange polished again.Flange surface after the reasonable setting polishing that the present invention passes through the steps such as deburring, corase grind, fine grinding and fine grinding is smooth, smooth.
Description
Technical field
The invention belongs to flange treatment technical field, more particularly, to a kind of flange polishing process.
Background technology
In the industrial production using quite varied, two pipelines, pipe fitting or equipment can be fixed flange by two flanges
Link together, be first individually fixed on a ring flange during connection, flange gasket then added between two ring flanges, finally
Two flanges are fastened together with bolt and are achieved that being connected between two objects, flange connection in addition is not used only
It is convenient, but also larger pressure can be born.But the polishing operation of flange surface is ripe not enough at present, polishing precision is not
It is enough.
The content of the invention
The present invention is for overcome the deficiencies in the prior art, there is provided a kind of flange that precision is high, surface is smooth of polishing is beaten
Mill method.
To achieve these goals, the present invention uses following technical scheme：A kind of flange polishing process, including following step
Suddenly：
（1）Remove flash removed：The burr of flange periphery and hole inwall is scraped off with scraper；
（2）Corase grind：With 200# dry abrasive papers polish flange surface, and with wire brush polish hole inwall；
（3）Fine grinding：Flange is placed on sander and polished, during polishing using 600# silicon carbide paper and open sander
On tap；
（4）Fine grinding：Flange after will be finely ground is removed from sander, and the sand paper on sander is replaced by 1000# water mill
Flange is polished again after sand paper.
The burr of flange surface is scraped off with scraper, is advantageous to the progress of next step polishing process,；Entered with 200# dry grinding paper
Row corase grind, it is smooth to be polishing to flange surface faster, is polished hole inwall with wire brush, can be so that inner wall smooth；By flange
Disk is placed on carries out fine grinding using the enterprising row of sander of 600# silicon carbide paper, and current are maintained on sander, can not only be timely
Rinse out flange surface and be polished the abrasive dust to get off, moreover it is possible to reduce temperature during flange polishing, further lift flange surface
Flatness and smoothness；Water mill is carried out to flange with 1000# water mill paper, caused abrasive dust can be direct by current in bruting process
Wash away, and then make it that the surface of flange is more smooth, smooth.
Further, before being roughly ground to flange, flange is first placed on immersion 30-40 minutes in water, taken after immersion
Go out flange and the moisture of flange surface is blotted with Water adsorption towel；Flange is placed on immersion in water and prevented in ensuing technique for grinding
The situation that the polishing bits of middle flange surface are flown upward everywhere occurs, and improves the air quality of surrounding environment, is advantageous to polishing personnel
Health.
Further, flange is placed on polished on sander when, keep the surface of flange parallel with silicon carbide paper；Method
Blue surface is parallel with silicon carbide paper, and smaller to the extruding force of silicon carbide paper, therefore while flange surface planarization is kept, subtract
Lack the cutting output to flange, reduce the waste of material.
In summary, after the reasonable setting polishing that the present invention passes through the steps such as deburring, corase grind, fine grinding and fine grinding
Flange surface is smooth, smooth.
Embodiment
In order that those skilled in the art are better understood from the present invention program, it is right below in conjunction with the embodiment of the present invention
Technical scheme in the embodiment of the present invention carries out clear, complete description.
A kind of flange polishing process, comprises the following steps：
（1）Remove flash removed：The burr of flange periphery and hole inwall is scraped off with scraper；
（2）Corase grind：With 200# dry abrasive papers polish flange surface, and with wire brush polish hole inwall；
（3）Fine grinding：Flange is placed on sander and polished, during polishing using 600# silicon carbide paper and open sander
On tap；
（4）Fine grinding：Flange after will be finely ground is removed from sander, and the sand paper on sander is replaced by 1000# water mill
Flange is polished again after sand paper.
Preferably, before being roughly ground to flange, first flange is placed in water and soaked 30 minutes, flange is taken out after immersion
And the moisture of flange surface is blotted with Water adsorption towel；Flange is placed on immersion in water and prevents the flange in ensuing technique for grinding
The situation that the polishing bits on surface are flown upward everywhere occurs, and improves the air quality of surrounding environment, is advantageous to the body of polishing personnel
Health.
Further, flange is placed on polished on sander when, keep the surface of flange parallel with silicon carbide paper；Method
Blue surface is parallel with silicon carbide paper, and smaller to the extruding force of silicon carbide paper, therefore while flange surface planarization is kept, subtract
Lack the cutting output to flange, reduce the waste of material.
Obviously, described embodiment is only the part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, it should all belong to the scope of protection of the invention.
