AI Technical Summary
In the production of asymmetric cross-section curved profiles, existing technologies suffer from uneven material flow and significant frictional losses, leading to instability in the extrusion process and affecting product quality and dimensional accuracy.
Design an extrusion device with multiple flow channels inside the flow channel component. The curvature of the second channel is greater than that of the third channel. The central axis of the flow channel outlet is inclined. The die covers the flow channel outlet and has an opening. The height of the outlet end of the opening is greater than that of the inlet end. By controlling the feed speed of the extruder, the material flow direction is adjusted to achieve shear deformation and uniform flow of the material.
It improves the uniformity of material flow and the stability of the extrusion process, enhances the dimensional accuracy and welding quality of extruded parts, reduces frictional loss, and optimizes the microstructure.
