The metal polishing tool comprises an air bag, the air bag has a polishing cloth as a working surface at the front end, the air bag is mounted in a holder; the holder is mounted on a rotating shaft, and the rotating shaft is sleeved a sleeve, the sleeve is airtightly connected to the rotating shaft, the sleeve is provided with an external air source inlet, the metal polishing tool comprises an air bag, and the front end of the air bag has a polishing cloth as a working surface. The airbag is mounted in a cage; the cage is mounted on a rotating shaft, the rotating shaft sleeves a sleeve, and the sleeve is airtightly connected to the rotating shaft, The casing is provided with an external air source inlet and an overflow valve; an air flow passage is formed in the rotating shaft in the sleeve, and the air flow passage is in communication with the airbag.
The invention provides a passive airbag pressure control mold curved flexible polishing tool with high polishing efficiency, high polishing quality, convenient on-line control and convenient local surface precision correction.
Metal polishing tools are divided into three types: hand polishing tools, electric polishing tools and new polishing grinding heads. This article describes the three polishing tools in detail.
(1) Hand polishing tools
1) Flat polisher. The material of the polisher handle is hardwood. On the polished surface of the polisher, a properly sized groove is cut with a knife, and a stop groove for winding the cloth product is engraved at a position slightly higher than the polished surface.
When grinding is performed using a coarse-grained abrasive, it is only necessary to apply the abrasive paste to the polishing surface of the polisher for polishing.
If polishing is carried out using very fine ultrafine powder (such as w1), the artificial leather can be wound on the grinding surface, and the abrasive grains are placed on the artificial leather and wrapped with nylon cloth, and the wire is tightly wrapped along the stopper groove. After polishing.
If polishing is carried out with finer abrasives, the abrasive can be placed on artificial leather wrapped with nylon cloth and then wrapped with coarse cotton or flannel for polishing. In principle, the finer the abrasive grains, the softer the fabric is wrapped. Only abrasive particles of the same particle size can be used for each type of polisher. Various polishers should not be mixed together and should be kept in a special sealed container.
2) Polishing machine for spherical surface. The spherical surface polisher is manufactured in substantially the same manner as the planar polisher. The polished surface of the polished convex workpiece must have a radius of curvature greater than the radius of curvature of the workpiece by 3 mm, and the polished surface of the polished concave workpiece has a radius of curvature smaller than the radius of curvature of the workpiece by 3 mm.
3) A polishing machine for free-form surfaces. For flat or spherical polishing operations, the size of the polisher is not concerned because of the positional relationship between the abrasive surface and the polisher. However, the free-form surface is continuously changed, and when the polishing device is too large, the shape of the surface of the workpiece is easily damaged. Therefore, for free-form surfaces, a small polisher should be used for polishing. The smaller the polisher, the easier it is to simulate the shape of a free-form surface.
(2) Electric polishing tools
Due to the large amount of manual polishing work on the mold part surface. Therefore, the application of electric polishing machines is being gradually expanded in the mold industry to improve polishing efficiency and reduce labor intensity. The electric polishing tool used is the grinding and polishing aid described above.
