摘 要
摘要:屏屏板工件采用沖孔落料級進模制造，級進模是一種工位多、效率高的沖模。在一副級進模上，根據沖壓件的實際需要，按一定順序安排了多個沖壓工序（在級進模中稱為工位）進行連續(xù)沖壓?？傊夁M模比單工序模生產率高，減少了模具和設備的數(shù)量，工件精度較高，便于操作和實現(xiàn)生產自動化。對于特別復雜或孔邊距較小的沖壓件，用簡單?；驈秃夏_制有困難時，可用級進模逐步沖出。但級進模輪廓尺寸較大，制造較復雜，成本較高，一般適用于大批量生產小型沖壓件。

Abstract:The screen screen board work piece uses the punch holes to fall the material level to enter the mold manufacture, the level enters the mold is one kind of location are many, efficiency high dying. Enters on the mold in a level, according to the pressing part actual need, arranged many ramming working procedure according to the certain order (to enter in mold in level to be called location) to carry on the continual ramming. In brief, the level enters the mold compared to the single working procedure mawson production rate high, reduced the mold and the equipment quantity, the work piece precision is high, is advantageous for the operation and the realization production automation. Regarding is specially complex or the hole edge distance small pressing part, stamps out with the Jan single model or the superposable die when has the difficulty, may use the level to enter the mold gradually to run out. But the level enters the mold overall size in a big way, manufacture complex, the cost is high, is suitable generally for the mass production small pressing part.
