全自动磁粉探伤机
Full-automatic magnetic particle flaw detector
全自动磁粉探伤检测流水线是主要为大批量的工件检测而设计的，除人工观察裂纹外，其它动作均自动完成。采用固定流水式，主要由电器控制系统、机械流水线传输系统和输送式远离法退磁系统等组成。电器控制部分集中安装在电源控制柜内，由磁化周向电源系统、纵向磁化电源系统、电气控制系统（包含PLC控制系统）、复合磁化系统、紫外线灯及暗室系统，暗室照明系统构成；机械系统由流水线传输系统（由电机和输送带传输系统），电极夹持系统（气缸和磁化电极）、磁悬液喷洒、过滤及回收系统构成，远离法退磁系统由高场强退磁线圈、减速机电机、输送带传输系统组成。
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.
一次性复合磁化可检查出工件表面和近表面因锻造、热处理、机械加工和疲劳而引起的裂痕等细微缺陷，磁化喷淋后经过人工观察有无缺陷，设备探伤完毕后，由于批量较大，观察完毕后由输送带退磁，速度快、效率高。
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.
