Embodiment 1
[0037] Taking A356 cast aluminum alloy as an example, the forming process of the metal rheological purification pressure forming equipment of the present invention is as follows: first, operate in the magnetic slag purification device 1, and pour the A356 melt onto the inclined runner 104 of the magnetic slag purification device 1 , the A356 melt flows along the inclined runner 104 to the outlet located at the bottom of the side wall of the box body 101, and under the magnetic force of the NdFeB permanent magnet plate 108, the magnetic slag in the A356 melt will be attracted to the inclined runner In the groove 105 on the surface of 104, the solid-liquid separation of the magnetic slag is completed. When the A356 melt is close to flow, the inclined runner 104 is lifted by the handle 103, and the remaining A356 melt flows to the direction of the discharge port until it is inclined The sprue 104 is close to the side wall where the outlet is located, and the excess A356 melt will ...

A metal rheological purification pressure forming equipment, belonging to the field of metal material processing technology, including a magnetic slag purification device, a shear filter slag device and a forming device, the outlet of the magnetic slag purification device and the inlet of the combined flow channel of the shear filter slag device The outlet of the combined flow channel of the shearing and filtering device is connected to the feed inlet of the forming device; this equipment can process various types of metals, continuously remove magnetic impurities, filter slag inclusions and shear metal fluids in one process. The bottom of the cavity is filled and the movable mold at the top is pressed downwards to finally prepare metal parts and plates with uniform and fine grains. Installing or removing the NdFeB permanent magnet plate can control whether the inclined plate sprue has the function of purifying magnetic impurities. Installing or removing the titanium alloy screen can add or remove the shear filtering function. The shape of the part can be changed by installing molds with different cavities. , modular design, short process flow, and production efficiency is much higher than traditional liquid slag removal and then forming processing equipment.
Description
technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a metal rheological purification pressure forming equipment. Background technique [0002] The rheological forming process is to directly shape the semi-solid slurry, so it has the advantages of energy saving, short process, low production cost, high production efficiency, simple equipment, and a wide range of alloys suitable for semi-solid processing. Compared with high-pressure casting, vacuum die-casting, and squeeze-casting, rheological deformation can effectively reduce defects, and the utilization rate of material properties is higher than that of similar castings. Compared with isothermal die forging or superplastic forging, the mass utilization rate of rheological forming materials is close to that of high pressure casting materials, which is much higher than that of isothermal die forging or superplastic forging. It can form parts with compl...
