粉末冶金零件的粉末成形压机、模架及成形能力发展趋向

成形复杂形状结构零件的粉末压机现在已和用于压制硬质合金刀片或简单形状零件的成形压机分开,清楚地形成了市场的一个组成部分.硬质合金产品要求压机的轴向精度非常高,而且拣拾-码放设备的生产率也要高.对于几何形状简单的结构零件与低密度零件,仍在很好地采用传统的压机设计,特别是快速、可靠地机械式压机.对于形状复杂、密度较高的零件...

TRENDS IN POWDER PRESSES,TOOLING AND SHAPING CAPABILITES FOR PM PARTS

Powder presses for complex structural parts have become a market sector clearly separated from presses for hardmetal inserts or simple parts.For hardmetal products extreme axial precision is re-quired at high productivity with pick-and-place equipment.For geometrically simple structural parts and low densities traditional press designs are still rendering good service,especially the fast and reli-able mechanical types.For complex higher density components multilevel die set presses have been accepted by the...
