Technical standard for quality inspection of steel wheel
1. The appearance is smooth, the steel wire is distributed evenly, and there is no local silk missing.
2, 100*10*20 cup type steel wire wheel, center cover 3mm thick A3 steel material.
3, the highest work line speed of 60 meters / sec, work speed of 11465 RPM / min, high-speed rotary machine test by 1.5 times.
4, wire wheel nonconcentricity is less than or equal to 0.40mm.
5, plywood: material 08F board, 1.2mm thickness.
6, the steel wire wheel specifications:? 0.3~0.4mm mixed ratio in production. Material: mechanical properties with YB248-64 II alpha group, 0.3~0.4mm?. The tensile strength of steel (1 b) =225~270kg/mm2; 0.4 steel?
(1 b) =220~265kg/mm2. The breaking force of steel wire tie test is 50% of the breaking force.
