Abstract：

In order to meet the precision blanking requirement of LED lamp cooling holder spindle for 6061 aluminum alloy, the compound extrusion forming process scheme was designed according to the characteristics of the shape and structure of part. Then, the extrusion processes under different aluminum blank sizes and extrusion speeds were simulated by FEA software DEFORM-3D, and the simulation results of stroke-load curve and metal flow distribution for above different processes were researched. Finally, the relatively optimal size of Φ56 mm×43 mm and the extrusion speed of 30 mm·s-1 were selected, and the equipment debugging and production verification were conducted. The results show that the extruded parts are basically consistent with the simulation results, and the quality and performance are stable and improved. Compared with the original cutting process, the raw material is saved by 66%.
