The device comprises a male die, a female die, two heating electrodes, a male die returning piece, a boosting coil assembly, a driving plate, a heating piece and an electromagnetic driving piece, wherein the heating electrodes are fixed on the female die; a plate to be formed is fixed on the heating electrodes; the male die comprises a fixing part and a forming part; the forming part is matched with the female die; the driving plate is fixed above the fixing part; the boosting coil assembly is electrically connected with the electromagnetic driving piece; the boosting coil assembly is fixedly arranged on the inner wall of an outer fixing frame and faces the driving plate; and the forming part penetrates out of the outer fixing frame to carry out blanking on the plate to be formed. According to the current assisted electromagnetic blanking device, current heating assists in electromagnetic blanking, and the problem that blanking on amorphous alloy cannot be implemented by the traditional process at present can be solved.

Description

technical field [0001] The invention relates to the technical field of plastic forming of amorphous alloy materials, in particular to a current-assisted electromagnetic blanking processing device and a control method thereof. Background technique [0002] Amorphous alloy is a new kind of engineering material, which has the characteristics of high strength, high elasticity, corrosion resistance and processability in molten state. The atomic structure arrangement of amorphous alloys is not the long-range order pattern of crystalline alloys. Amorphous materials are generally obtained by cooling molten alloys from above the melting temperature of the crystalline phase to below the "glass transition temperature" of the amorphous phase at a "sufficiently fast" cooling rate so as to avoid nucleation and growth of alloy crystals. The "critical cooling rate" of early amorphous materials was extremely high. Therefore, conventional machining techniques are not suitable for such high ...

Problems solved by technology

However, at present, the difficulty of its processing and forming has limited its application to a certain extent. Now, the method of heating the amorphous alloy to the "processing temperature" by current-assisted heating combined with electromagnetic boosting punching is used to process the amorphous alloy material.
