The invention relates to the field of electroplating equipment, in particular to a magnetic conductance type barrel plating device. The magnetic conductance type barrel plating device comprises an electroplating tank, an anode block, cathode plates, a stand column, internal magnetic modules, external magnetic modules, a first motor, a second motor, a drying module and a controller, wherein the anode block is located at the bottom of the electroplating tank; the cathode plates are installed on the inner walls of the electroplating tank; the stand column is coaxial with the electroplating tank; the internal magnetic modules and the external magnetic modules are installed on the stand column through a support and can rotate around the stand column in the opposite directions; the internal magnetic modules are located on the inner side of the electroplating tank, and the external magnetic modules are located on the outer side of the electroplating tank; the first motor is used for driving the internal magnetic modules to rotate, and the second motor is used for driving the external magnetic modules to rotate; and the drying module is used for drying electroplated parts. According to the magnetic conductance type barrel plating device, the to-be-plated parts are driven to move by alternate magnetic fields, the traditional mode that the to-be-plated parts are driven to move by rollers is replaced, and the problem that electroplating liquid is distributed unevenly can be solved. Meanwhile, the magnetic conductance type barrel plating device can perform electroplating on different to-be-plated parts simultaneously, and the electroplating effect is good.
