AI Technical Summary
Existing metal ingot blanking methods suffer from low yield, uneven microstructure, and processing difficulties. In particular, difficult-to-deform metals are prone to microstructural defects and surface inhomogeneity of extruded bars during forging and extrusion processes.
A bidirectional extrusion blanking device is adopted, which drives the metal ingot blank to be bidirectionally extruded through a "Y"-shaped combined channel and a power plate. Combined with the upward force provided by the magnetic field generator, the bidirectional extrusion blanking of the metal ingot blank is realized. The power protrusions are distributed on the power plate according to a specific pattern to promote rotation and uniform extrusion.
It improves the yield and microstructure uniformity of metal ingots, reduces the residue from risers in traditional extrusion processes, lowers operational difficulty, and improves the production efficiency and material utilization of powder metallurgy components.
