轴承座冲压模具设计(含零件图,装配图)(含任务书,开题报告,毕业论文说明书9000字,cad图纸10张)
摘要
本课题研究的内容主要是设计一副生产轴承座的模具，采用复合模，该模具中落料凸模和凹模首先接触条料，并与推件块一起压住条料，先落料，再拉深冲孔同时进行，当上模回程时落料后的条料由刚性卸料板从凸凹模上卸下，成型零件由打料杆打下，手动取出制件，由于是手动取出，一定程度的影响了工作效率。本模具的材料利用率为63%，材料利用率一般。
制件的尺寸较大，对冲压设备和模架的要求较高，模具的结构也较为复杂，模具的制造成本也相应提高。
本模具能够满足生产要求。
关键词：复合模、刚性卸料、凸凹模
Abstract
This topic research content mainly is designs a production bearing seat the mold,Uses the superposable die,This mold declines the material raised mold and the concave mold first the contact bar material, And with pushes a block to suppress the strip material together,Falls the material first,Again also the drawing punch holes carries on, After top die return trip falls the material the strip material to unload the yard lumber by the rigidity to dismount from the convex-concave mold,Takes shape the components by to hit the material pole to overcome,Manual takes out the workpiece, Because is manual takes out,Certain degree influence working efficiency. This mold material use factor is 63%,The material use factor is ordinary. The workpiece size is big,Is high to the ramming equipment and a mold request,The mold structure is also complex,The mold production cost also correspondingly enhances.
This mold can satisfy the production request.
Key word:Superposable die, rigid ex-denning, convex-concave mold
零件图
此零件为轴承座，是典型的冲压件。工件尺寸步太大，表面质量要求不太高。材料厚度为2.5mm，为中批量生产，每月2000～4000件。所用材料为08钢，由于含碳量≤0.25％，属于极软低碳钢。强度、硬度很低，塑性、韧性极好，冷加工性好，淬透性、淬硬性差。
