連桿半自動(dòng)熒光磁粉探傷機
Semi-automatic fluorescent magnetic particle flaw detector for connecting rod
流水線(xiàn)為固定式機電分離結構、半封閉結構，主要由機械系統、磁化電源、電氣控制系統、電極夾持系統、磁化機構（周向通電、縱向線(xiàn)圈）、磁懸液噴灑回收系統、熒光照明系統、退磁系統、整體暗室等幾部分組成。適用于以濕式磁粉法檢測連桿工件的表面及近表面因材料、鍛壓、淬火、加工、疲勞等原因引起的裂紋和各種細微缺陷。
The assembly line is of a fixed electromechanical separation structure and a semi-closed structure, and mainly consists of a mechanical system, a magnetizing power supply, an electrical control system, an electrode clamping system, a magnetizing mechanism (circumferential electrification and longitudinal coils), a magnetic suspension spraying recovery system, a fluorescent lighting system, a demagnetizing system, an integral darkroom and other parts. It is suitable for detecting cracks and various minor defects on the surface and near surface of connecting rod workpieces caused by materials, forging, quenching, processing, fatigue and other reasons by wet magnetic particle method.
該流水線(xiàn)設備具有自動(dòng)、手動(dòng)兩種運行模式，由可編程邏輯控制器（PLC）對設備集中控制。手動(dòng)時(shí)，可進(jìn)行每個(gè)動(dòng)作的單步獨立操作；自動(dòng)時(shí)，該設備自動(dòng)執行PLC內部程序，根據連桿工件，采用不同的輔助工具（托架及夾具）。該設備采用交流磁化方式，帶斷電相位控制，具有較高剩磁穩定度，既適用于連續法探傷檢測，又適用于剩磁法探傷檢測。復合磁化在工件上形成疊加磁場(chǎng)，一次性顯示磁跡，具有較高的檢測效率。同時(shí)配置合格的退磁機，將穩定的剩磁退干凈。
The pipeline equipment has two operation modes of automatic and manual, and is controlled centrally by a programmable logic controller (PLC). For manual operation, single-step independent operation of each action can be performed; When automatic, the equipment automatically executes PLC internal programs, and different auxiliary tools (brackets and clamps) are adopted according to connecting rod workpieces. The equipment adopts AC magnetization mode with power-off phase control and has high remanence stability, which is suitable for both continuous flaw detection and remanence flaw detection. The composite magnetization forms a superimposed magnetic field on the workpiece and displays magnetic traces in all directions at one time, thus having higher detection efficiency. At the same time, a qualified demagnetizer is configured to clean up the stable remanence.
