Electrode adjusting device and method for aluminum alloy solidification electric pulse treatment

Abstract

The invention provides an electrode adjusting device and method for aluminum alloy solidification electric pulse treatment, and belongs to the technical field of aluminum alloy casting. The problems that an existing electrode adjusting device is inaccurate in adjustment, poor contact between an electrode and molten aluminum alloy is prone to occurring, and disassembly is inconvenient after the molten aluminum alloy is solidified are solved. The device comprises a rack, Z-direction motors, lead screws, T-shaped nuts, a pulse power supply, an electrode insertion mechanism, a belt, a synchronous belt wheel and an X-direction motor, the left side and the right side of the rack are each provided with one Z-direction motor, the output end of each Z-direction motor is connected with one lead screw, and each lead screw is matched with one T-shaped nut; the two Z-direction motors synchronously rotate to drive the lead screw to rotate, and the lead screw rotates to drive the T-shaped nut to ascend and descend so as to drive the electrode insertion mechanism to ascend and descend. When the output shaft of the X-direction motor rotates, the two electrode insertion assemblies are driven to be close to or away from each other. The device is reasonable in structure, convenient to use, rapid, efficient and capable of achieving rapid adjustment of the distance and depth of the electrodes.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy casting, and in particular relates to an electrode adjustment device and method for electric pulse treatment of aluminum alloy solidification. Background technique [0002] In the 1990s, Nakada et al. applied the high-voltage electrical pulse generated by capacitive discharge to the solidification process of Sn-15%Pb alloy, and the solidification structure was significantly improved. In the following 20 years, electrical pulses have attracted much attention as a new metal refining technique. In recent years, with the development of technology, in the field of electric pulse refining metal technology, many scholars have begun to study the way electrodes act on the metal, the effect of electrode spacing and the depth of contact with aluminum alloy melt on the structure. However, the existing electrode adjustment device for electric pulse treatment of aluminum alloy solidification has problem...
