不言而谕,模具的磨损对锻件质量有着严重的影响,模具费用一般占生产成本的7～10％,生产中由于模具磨损和产生故障而进行的模具修理、模具更换等所损失的时间约占实际生产时间的10、13％。影响模具寿命的因素很多,诸如模具设计、模具制造质量、锻造温度、所采用的锻造设备种类、操作工人的技术熟练程度、模具润滑、模具材料等。一、模具磨损分析 1.模具磨损的机理模具磨损的机理以A·Kannappan的分析为准来加以说明。图1是环形模锻件,其中:
It goes without saying that mold wear has a serious impact on the quality of forgings, mold costs generally account for 7 to 10% of the cost of production, due to mold wear and failure of the mold repair, mold replacement, lost about time Accounting for the actual production time of 10,13%. Die life affect many factors, such as mold design, mold manufacturing quality, forging temperature, the type of used forging equipment, skilled workers, mold lubrication, mold materials. First, the mold wear analysis 1 die wear mechanism Die wear mechanism to A. Kannappan analysis subject to be described. Figure 1 is an annular die forging in which:
