Embodiment 1

[0017] A flange grinding method, comprising the steps of:

[0018] (1) Soaking: Soak the flange in a special solution for 20 minutes; specifically, the special solution is prepared by cleaning agent and water at a ratio of 1:40. After the preparation is completed, stir it with a mixer for 25 minutes before putting it into the Soak the flange; (2) Coarse grinding: take out the soaked flange and dry it with a cotton cloth, and then use 100# dry sanding paper for grinding; (3) Fine grinding: Rinse off the abrasive debris attached to the flange surface with water , then dry the flange, and use 400# dry grinding paper to grind the flange; (4) fine grinding: wash off the grinding debris attached to the surface of the flange after fine grinding with water, then dry the flange, use Grind the flange with 800# water grinding paper; (5) Water grinding: place the finely ground flange under the faucet, and grind the flange with 1000# water grinding paper until the surface of the flange is ...

Embodiment 2

[0021] A flange grinding method, comprising the steps of:

[0022] (1) Soaking: Soak the flange in a special solution for 30 minutes. Specifically, the special solution is prepared by cleaning agent and water at a ratio of 1:40. After the preparation is completed, stir it with a mixer for 25 minutes before putting it in Soak the flange; (2) Coarse grinding: take out the soaked flange and dry it with a cotton cloth, and then use 100# dry sanding paper for grinding; (3) Fine grinding: Rinse off the abrasive debris attached to the flange surface with water , then dry the flange, and use 400# dry grinding paper to grind the flange; (4) fine grinding: wash off the grinding debris attached to the surface of the flange after fine grinding with water, then dry the flange, use Grind the flange with 800# water grinding paper; (5) Water grinding: place the finely ground flange under the faucet, and grind the flange with 1000# water grinding paper until the surface of the flange is smooth...

Abstract

The invention discloses a flange grinding method, which comprises the following steps: (1) Soaking: Soak the flange in a special solution for 20-30 minutes; (2) Rough grinding: Take out the soaked flange and dry it with a cotton cloth, Then use 100# dry sandpaper for grinding; (3) Fine grinding: wash off the grinding debris attached to the flange surface with water, then dry the flange, and use 400# dry sandpaper to polish the flange; ( 4) Fine grinding: Rinse off the grinding debris attached to the surface of the flange after fine grinding with water, then dry the flange, and use 800# water grinding paper to polish the flange. The present invention soaks the flange in the solution before grinding, so that the grinding debris produced in the subsequent grinding process is not easy to fly, improves the surrounding air quality during the grinding operation, and reduces the damage to the health of the operator. , fine grinding, fine grinding, water grinding and drying treatment and other steps are reasonably set to make the flange surface smooth and flat after grinding.

Description

technical field [0001] The invention belongs to the technical field of flange processing, and in particular relates to a flange grinding method. Background technique [0002] Flanges are widely used in industrial production. Two pipes, pipe fittings or equipment can be fixedly connected together by two flanges. The upper flange pad, and finally the two flanges are fastened together with bolts to realize the fixed connection between the two objects. In addition, the flange connection is not only convenient to use, but also able to withstand greater pressure. However, the grinding process of the flange surface is not mature enough at present, and the grinding debris generated during grinding is easy to fly everywhere, and then the ambient air quality around the grinding workbench is poor, causing great harm to the operators. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a flange grinding method that...
