Assembly platform

The characteristics of gray cast iron parts: wear resistance and good shock resistance, because of graphite in the cast ironis conducive to lubrication and oil storage, so good wear resistance. Similarly, due to the existence of graphite, the shockresistance of gray cast iron is better than that of steel. Process performance is good, because of the high carbon content ofthe gray cast iron, close to the eutectic composition, so relatively low melting point, good fluidity, shrinkage of small, so it issuitable for casting of complicated structure or thin-walled castings, the graphite machining easy formation of chip breaking,so grey cast iron can machinability is superior to that of steel.

Product description

Assembly platform use: applied to the assembly and commissioning of power machinery and equipment, the surface with a T-shaped groove, can be fixed power machinery and equipment, require a larger assembly platform, can be assembled and used.

Assembly platform material: high-strength cast iron HT200-300.

The assembly platform has a working surface hardness of HB170-240and has been manually treated twice (manual annealing 600 degrees -700 degrees and natural aging for 2-3 years) make the product's accuracy stable and wear-resistant.

Assembly platform specifications:100 x 100 - 3000 x 6000,(largein the assembly platform of this specification can be assembled to use or custom-made by drawing) degree: press Standard measurement and verification procedures are implemented, 0,1,2,3 Four levels.

Technical requirements:

　　1,the assembly platform work surface shall not have serious impact on theappearance and performance of sand holes, pores, cracks, slag, shrink, scratches, bumps, rust spots and other defects.

　　2,the casting surface of the assembly platform should be cleared of sand and flat, painted firmly.

　　3,accuracy registered as level 0 -3 plate work surface, diameter less than 15mm The sand holes allow for clogging with the same material, and the hardness should be less than that of the surrounding material. No more than 4 sand holes should be blocked on the face and no less than 80mm spacing between the sand holes.

　　4,the assembly platform should be made of fine gray cast iron or alloy materials, the working surface hardness should be 170-220HB.

　　5,assembly platform work surface should usually use scraping process. For level 3 plate face with scraping, the large allowable value of surface roughness Ra is 5um .

　　6,flatness tolerances are shown in Table 2.

　　7,the use ofscraping process should be color-coated to research inspection. The ratio of contact point area displayed after research is shown in Table 3: or contact points by 25mm x 25mm square area see Table 3 and should be no greater than 5 points between contact points in any 25mm x 25mm.

Assembly platform (assembly platform) production process should generally strictly use the "People's Republic of China Machinery Industry Standard"JB/T 7974-2000 processing and production. But sometimes also have to adapt to the local, according to the design. In the assembly plate assembly plate standards and enterprise standards and assembly plate use requirements have out of, according to the actual needs of the assembly plate special design. The concept of designing and assembling plates should be based on a low cost to achieve good use effect, Good use effect also needs to achieve the production and use of both sides have the principle of mutual benefit. The assembly plate is usually rectangular or square in shape. The standard also provides for a circular, circular, but the round and ring assembly plate sits still need to be custom-made by the user.
