There must be precise flatness. To have precise flatness, the following conditions must be met: 1. Thickness requirements: mainly include the thickness of the working surface on the platform, the thickness and height of the side panels, and the thickness and height of the bottom rib plate and density.
2. Material requirements: high-strength cast iron H, hardness: HB.
3. Annealing: After excessive high temperature annealing and aging treatment in the tempering kiln.
4. Natural aging: According to the national standard, it should be one year of natural aging. Since this process takes too long, companies cannot wait that long due to the impact of capital turnover, so they often use exciters to pass vibration aging instead. Although the effect of this process is not yet clear, it is commonly used internationally.
5. Trachoma and pores: Trachoma and trachoma are not allowed on the level and level platforms. The pores and trachoma can be filled with solid materials of the same material as the platform. Note: The hardness of the filler must be lower than the hardness of the platform itself.
6. Scraping process: Scraping is the most important process in the processing of cast iron platforms. It determines the flatness error and the number of contact points on the working surface. A grade plate platform shall be no less than a point grade plate platform within a range of ㎜ square on each side. A grade plate platform shall be no less than a point grade plate platform within the range of ㎜ square on each side. It shall be no less than a point grade plate platform within the range of ㎜ square on each side. There shall be no less than one point within the range of mm square on each side. After the scraping is completed, the four edges of the platform will be blunt.
7. Sand cleaning and painting: The bottom surface of the platform must be thoroughly sanded, clean and sprayed with red anti-rust paint. The sides should be flat before painting, usually with basket paint or green paint.
8. Packaging requirements: Mainly wooden packaging, try to use thick wood to cover the working surface of the platform, and make fully enclosed packaging if necessary. Anti-rust measures must be taken on the platform working surface before packaging.
9. Transportation requirements: After loading the platform, check whether there is any suspension. If there is any suspension, pad it firmly to avoid vibration. Do not stack the platforms too high to avoid squeezing and deformation.
10. Selection of accessories: Mainly the selection of brackets. The brackets are made of square steel and angle iron with a wall thickness of m. The welding density and structure must be reasonable, and the adjusting bolts must rotate smoothly.
11. Installation and debugging: Generally, a frame level is used for leveling first, and then an optical level or an electronic level is used to measure the flatness error. If there are any problems, please ask the platform manufacturer to come to the site to correct the problem.
