Description

A metal rheological purification pressure forming equipment

technical field

The invention belongs to the technical field of metal material processing, and particularly relates to a metal rheological purification pressure forming device.

Background technique

The rheological forming process is to directly form 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, and parts with complex shapes and large sizes can be formed. And reduce the tonnage and energy consumption of the forming equipment. Therefore, rheological forming is known as one of the most potential forming technologies for metal materials in the 21st century. The raw material used in rheological forming is a semi-solid slurry with thixotropy, which can achieve smooth filling and effectively avoid the involvement of gas, oxides and coatings; the semi-solid slurry contains 40% to 60% of solid phase, The solidification shrinkage is small; the size of the inner gate section of the mold is large, which is conducive to the transfer of pressure and the feeding of the liquid metal, avoiding shrinkage holes and reducing thermal cracking.

In theory, rheologically formed materials have the advantages of low defects, high density, high mechanical properties and high consistency. But the huge difference between theory and practice stems from the problems of rheological deformation involving defects and intergranular segregation. Involvement defects mainly occur in the preparation stage of semi-solid slurry, and intergranular segregation occurs in the forming stage of semi-solid slurry. The essential difference between rheological deformation and traditional forging and casting is that the raw material used is a semi-solid slurry with thixotropy, while the entrainment defects and intergranular segregation are caused by the semi-solid slurry. Therefore, the present invention is used for The purification process of metal rheological forming, and the uniform fine-grained, slag-sparse plates, parts, etc. are prepared by pressure forming. The metal rheological purification pressure forming equipment has compact structure, modular design, strong versatility, good expansibility, high integration, saving and environmental protection, and high production efficiency, and can continuously remove magnetic impurities, filter slag inclusions and shear in one process. The metal fluid is cut to break the dendrites, and finally the required parts and plates are produced by a pressure die.

Installing or removing the NdFeB permanent magnet plate can control whether the inclined plate runner has the function of magnetic impurity purification. Installing or removing the titanium alloy screen can add or remove the shear filter function. The shape of the part can be completed by installing molds with different cavities.
