活門沖壓工藝及級進模具設計摘 要：本設計題目為活 門 件 沖裁模，體現(xiàn)了典型沖裁模的設計要求、內(nèi)容及方向，有一定的設計意義。通過對該模具的設計，加強了設計者對沖裁模設計基礎知識的理解和運用，為設計更復雜的沖裁模具做好了鋪墊。本設計運用沖裁工藝及模具設計的基礎知識，首先分析了板材的性能要求，為選取模具的類型做好了準備；然后計算了沖裁件的沖裁力，便于選取壓力機噸位及確定壓力機型號；最后分析了沖裁件的特征，便于確定模具的設計參數(shù)、設計要點及卸件裝置。本設計采用了沖孔—落料級進模成形活 門 制 件 。成形原理可劃分為兩個階段：首先沖孔凸模與凹模共同作用先沖出活門制件上的孔，而后利用第一步?jīng)_出的兩個 10mm 的半圓孔做精確定位使外形凸模與凹模共同作用使工?件落料成形。關鍵詞： 沖孔—落料級進模 沖孔凸模 凹模 壓力機噸位 The valve ramming craft and the level enter the mold designAbstract: This design topic for the valve punching die, has manifested the typical punching die design request, the content and the direction, has certain design significance.Through to this mold design, strengthened the designer to the punching die design elementary knowledge understanding and the utilization, for designed the more complex blanking mold to complete the upholstery.This design the elementary knowledge which designs using the blanking craft and the mold, first has analyzed the plate performance requirement, for selected the mold the type to prepare for; Then has calculated the blanking blanking force, is advantageous for the selection press tonnage and the definite press model; Finally has analyzed the blanking characteristic, is advantageous for determines the mold the design variable, the design main point and the shedder.This design used the punch holes - to fall the material level to enter the mold forming valve workpiece.The formed principle may divide is two stages: First the punch holes raised mold and the concave mold affect together run out on the valve workpiece first the hole, after but uses two 10mm half round hole which first step runs out to make the pinpointing to cause the contour raised mold and the concave mold affects together causes the work piece to fall the material forming.Key word: The punch holes - fall the material level to enter the mold punch holes raised mold Concave mold Press tonnage
