Full-automatic magnetic particle flaw detector
The full-automatic magnetic particle inspection assembly line is mainly designed for mass inspection of workpieces, and all other actions are automatically completed except manual observation of cracks. Fixed flow type is adopted, which mainly consists of electrical control system, mechanical flow line transmission system and conveying type remote demagnetization system. The electric appliance control part is centrally installed in the power control cabinet and consists of a magnetization circumferential power supply system, a longitudinal magnetization power supply system, an electric control system (including a PLC control system), a composite magnetization system, an ultraviolet lamp, a darkroom system and a darkroom lighting system. The mechanical system consists of assembly line transmission system (composed of motor and conveyor belt transmission system), electrode clamping system (cylinder and magnetized electrode), magnetic suspension spraying, filtering and recovery system. The remote demagnetization system consists of high-field demagnetization coil, reducer motor and conveyor belt transmission system.
One-time composite magnetization can check out minor defects such as cracks on the surface and near surface of the workpiece caused by forging, heat treatment, mechanical processing and fatigue. After magnetization spraying, manually observe whether there are any defects. After equipment flaw detection is completed, due to large batch size, the conveyor belt demagnetizes after observation, with high speed and efficiency.
