| Abstract: | The backward extrusion forming of micro-component has a higher requirement for the data acquisition equipment. Based on the process characteristics of backward extrusion for micro-component, a set of data acquisition equipment was developed, and its principle was stated. The equipment enabled a real-time acquisition of punch load and displacement data and a precision control of forming temperature. Experimental study on the backward extrusion of semisolid ZL101 aluminum alloy billets verified the data acquisition equipment. |
