Cast iron platform included : Three-dimensional flexible welding base platform, crossed platform, the basic platform, grinding platform, riveting platform, standard crossed platform, fitter platform clamp, T-slot platform (T-slot plate), rail trough iron platform cast iron rail , Inspection platform, assembly level, welding platform

Cast iron platform is widely used in the construction industry, printing industry, hydraulic equipment, construction industry, railway locomotive, instrument production, electronics industry, petrochemical, automotive, ceramic industry, railway locomotive, etc. in the course of the use of local wear should be avoided Too much, scratches and bumps, and the impact of flatness and service life, the life of the cast iron test platform under normal conditions should be long. After use should be cleaned, do a good job of anti-rust work to maintain the service life The

Cast iron platform technical requirements:

1, the platform must be twice after the stress stress aging treatment to prevent the deformation of the stress memory distortion and the future use of the platform in the occurrence of cracks in the phenomenon of elimination of casting stress, roughing the purpose of stress, stress relief of more than 90%

2, the face of processing at the end of sharp angle;

3, casting the external surface of the rough surface to be tired, polished, the inner surface are required to apply anti-rust paint;

4, flat face can not have a serious impact on the appearance and performance of sand holes, stomata, cracks, slag, shrink loose, scratches, bumps, rust and other defects.

3, the precision level of 0 to 3 on the flat face, the diameter of less than 15mm sand hole allows the same material to block, the hardness should be less than the same material hardness of the face of the sand hole should be no more than 4 And the distance between the sand holes should be not less than 80mm.

4, the plate should be used high-quality fine gray cast iron or alloy cast iron and other materials, the face hardness should be 170 ~ 220HB.

5, flat face is usually used in the use of scraping processing. For the use of scraping the processing level of the three flat face, the surface roughness Ra maximum allowable value of 5 ч m.

7, flat face with scraping process should be carried out on the color of the test. The post-show contact area ratio shown in Table 3, or by 25mm × 25mm in the contact points should not be greater than 5 points. Controversial, according to the ratio of contact area for the assessment basis.

8, flat on the two sides, there should be installed handle or ring device screw hole (or cylindrical hole), and the device location should be designed to minimize the deformation caused by handling.

9, if the flat face set on the working hole (or groove), the location should not be higher than the face.
