Jianxin Casting is a professional manufacturer of cast iron platforms. Supply Dalian cast iron platform, cast iron flat plate, iron floor and other cast products in stock or customized.
Jianxin Casting recently produced a batch of cast iron platforms for customers in Dalian, which have been packed and shipped. Thank you friends in Dalian for your trust and support.
The cast iron platform is produced according to the GB / 4986-85 standard. The products are made of ribbed plate and box type. The working surface has a square shape. The selected material is HT200. The working surface uses a scraping process. The working surface can be processed into V-shaped, T-shaped, U-shaped. Grooves and round holes, long holes, etc. The cast iron platform is a flat reference tool for workpiece inspection or scribing. The flat plate assembly should be set horizontally and the load is distributed on each fulcrum. When indoor temperature is used, vibration should be prevented.
2500 × 6000 × 300mm T-slot cast iron platform six pieces with attachment adjustment horn
2000 × 4000 × 200mm T-slot cast iron platform six pieces with attachment adjustment horn
In order to facilitate the adjustment, the horn should be exposed about 25-30 mm outside the cast iron platform. The distance between the two horns should be about 1 meter. The stability of the cast iron platform is relatively reduced. In order to accurately adjust the level and elevation of the platform, when the foundation is uneven, thin steel plates of 0.3, 0.5, 1 and 2 mm can be used to pad the horns. It has sufficient rigidity and stability. The top surface of each group of horns should be at the same level. The placement must be neat. The adjusted angle should be solid, stable, and then adjusted. , Avoid vibration during use.
First, the thickness meets the requirements: it mainly includes the working surface thickness, side wall thickness and height on the platform, as well as the thickness, height and density of the bottom ribs.
Second, the selected material meets the requirements: high-strength cast iron HT200-300, hardness: HB170-240.
Third, artificial annealing: annealing in the tempering kiln through a high temperature of 600-700 degrees.
Fourth, natural aging: According to international standards, it should be 2-3 years natural aging, because this process takes too long, and manufacturers can't wait that long due to working capital, and most of them are replaced by vibration aging. Although the effect of this process has not been established, it has been widely used internationally.
Five, trachoma and stomata: Level 0 and 1 platforms are not allowed to have pores and trachoma. Levels 2 and 3 can be filled with stomatal trachoma with the same material as the platform. Note: The hardness of the filler must be lower than the hardness of the platform itself.
6. Scraper process: Manual scraping is the most critical process in the production of cast iron platforms. It determines the flatness error of the cast iron platform and the number of accessible points on the working surface. The level 0 platform is not less than 25 points in the range of 25㎜ square on each side; the level 1 platform is not less than 20 points in the range of 25 每 square on each side; the level 2 platform is 25 on each side The range of ㎜ square is not less than 16 points; the level 3 flat platform is not less than 12 points in the range of 25 ㎜ square on each side. After the scraping is completed, the four edges of the platform are dull.
Seven, sand cleaning and painting: the bottom surface of the platform should be completely clean, clean and sprayed with red rust-proof paint. The side should be leveled before painting, generally painted with basket paint or green paint.
Eight, packaging meets the requirements: the main packaging is wooden boxes, as far as possible to use thick wood to cover the working surface of the platform, if necessary, do fully closed packaging. The anti-rust measures on the working surface of the platform must be done before packaging.
Nine, the transportation meets the requirements. After the platform is packed, check whether there is a suspension. If there is a suspension, it should be solidified to prevent vibration. The platform must not be placed too high to prevent crushing.
X. Selection of accessories: The main choice is the bracket. The bracket is made of square steel and angle iron with a thickness of 1.5-2mm. The welding density and structure must be scientific and reasonable. The adjustment bolts must be rotated smoothly.
