Description

Technical Field

[0001] The utility model relates to the technical field of metal sign surface treatment, in particular to a metal sign surface treatment device. Background Art

[0002] Metal signs are widely used in trademark identification, shop signs, advertising decorations and some guide signs with instructive nature, such as house numbers, building numbers, etc. In order to improve the appearance quality, increase wear resistance and enhance corrosion resistance, it is necessary to polish the surface. Use a polishing machine to polish the surface. Through grinding and polishing, the surface of the metal sign can become smooth and flat, and the surface particles, oxide scale, defects, etc. can be removed, thereby improving the overall appearance quality of the sign.

[0003] Specifically, when polishing is required, the surface fine polishing process is divided into three steps: coarse grinding, medium grinding and fine grinding. First, the macro-roughness of the surface is removed by coarse grinding, and then the scratches and particles generated by coarse grinding are further removed by medium grinding. Finally, the appropriate polishing wax is selected for fine grinding to achieve the ideal brightness. When polishing, irregular or small products are often encountered. The original fixture may not meet the fixing requirements. At this time, it is necessary to consider replacing the fixture. At the same time, the fixtures for placing metal signs are of fixed size and cannot adapt to metal signs of different sizes for fixing and polishing. Based on the above problems, we proposed a metal sign surface treatment device. Utility Model Content
