一、概述零件图是加工和检验零件的依据,零件图上的尺寸标注应满足以下要求: (1) 正确——尺寸注法符合国家机械制图标准; (2) 清晰——尺寸布局整齐清晰,一目了然,便于读图; (3) 齐全——尺寸不错、不漏,既不重复也不矛盾; (4) 合理——所注尺寸既能保证设计要求,又能适合加工工艺。冲孔落料连续模的凹模是整副模具中的关键零件,它的尺寸标注工作量大而繁复,为了全面达到上述四点要求,往往要求设计者具备丰富的专业知识和加工经验,並且要耗大量的
I. Overview The part drawing is the basis for machining and inspection of parts. The dimension drawing on the part drawing should meet the following requirements: (1) Correct - the dimensioning is in accordance with the national mechanical drawing standard; (2) Clear - the dimension layout is neat and clear, (3) complete - good size, no leakage, neither repeated nor contradictory; (4) reasonable - Note the size of both to ensure that the design requirements, but also for the processing technology. Punching blanking continuous die die is the key part of the whole vice mold, the size of the workload of its large and complicated, in order to fully meet the above four requirements, designers often require a wealth of expertise and processing experience, and To consume a lot
