Contact: Feng Gang Tel: 0317-8319626 Mobile: 15133799602 Work QQ: 545837729 platform assembly according to the type of gray iron castings, malleable iron and ductile iron, respectively, have different technical requirements, according to the conditions of the plant and the inspection and acceptance procedures inspection. In general, gray iron castings performed in GB976-67. Grade platform allowance, size deviation should meet the drawing requirements or comply with GB6414-1999 of. Ductile iron test can be performed GB1348-88. Material assembly platform for the pig iron charge usually selected according to GB718-82 selection, ductile pig iron by GB1412-78 selection. Standard installation according to the chemical composition of pig iron divided into several groups, class, grade, but does not consider the carbon content. Assembly platform / mounting plate Specifications Accuracy table: 200 * 200 ---- 3000 * 6000 (s special specification made to order) assembly platform / mounting plate material: high strength HT200-300. Face using scraping process, the working surface can be processed V-shaped, T-shaped, U-shaped groove, dovetail slots, holes, long holes and so on. Flat for workpiece detection or crossed the plane of the reference measuring tool. Assembly platform installation is raised to the level of the plate, the load being evenly distributed in the pivot. Ambient temperature (20 ± 5) ℃. Should be used to prevent vibration. Assembly platform for the production process in strict accordance with international standards, inspection standards a "People's Republic of China Machinery Industry Standard" JB / T 7974-1999. Inspection is generally divided into rough cast iron plate test, whether machining inspection and product testing twice a rough assembly platform appearance main test specifications can meet the technical requirements, and there is no internal defects rough; assembly platform machining cast iron plate test mainly aimed at testing There is no sand holes, pores, cracks, sand, shrinkage and processing errors, etc; product testing assembly platform is mainly Verify that the cast iron plate flatness and appearance can achieve the requirements and specifications. Assembly platform / assembly plate in the production process, will produce some theoretical weight deviation should be noted that the deviation of the cast iron plate iron plate is not affected by the use. Usually cast iron plate design should take into account the error of casting and machining error, cast iron plate weight error not normally exceed 10%, more than 10%, we want the quality of the cast iron plate of identification before they can make further determine the assembly platform whether you can put to use assembly platform / mounting plate Ordering step: Ordering assembly platform needs to be customized, the completion of our design (or your company) drawing confirmation, signed purchase and sale contracts.
