【摘要】 根据深小锥孔开式冷挤压的变形特点和影响因素,设计并完成了深小锥孔开式冷挤压内孔参数的实验。通过实验得到了深小锥孔开式冷挤压后内孔的母线型式,并通过实验分析得到了挤压后内孔锥度与挤压前坯料外锥度的比值(相对锥度)与坯料原始参数的关系曲线,为工程应用和理论分析奠定基础。更多还原

【Abstract】 Based on the characteristic distortion and the influence factors of the deep-thin and cone hole open-die cold extrusion,the experiment on hole parameters of the deep-thin and cone hole open-die cold extrusion is designed and completed,then the generatrix of the hole on the parts by extruded is obtain,the curves on the relation between the angle on the rough and the angle of the hole on the part by extruded are built更多还原
