限位板沖壓成形工藝與模具設(shè)計摘 要：本設(shè)計題目為限 位 板 沖裁模，體現(xiàn)了典型沖裁模的設(shè)計要求、內(nèi)容及方向，有一定的設(shè)計意義。通過對該模具的設(shè)計，加強了設(shè)計者對沖裁模設(shè)計基礎(chǔ)知識的理解和運用，為設(shè)計更復雜的沖裁模具做好了鋪墊。本設(shè)計運用沖裁工藝及模具設(shè)計的基礎(chǔ)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(shè)計參數(shù)、設(shè)計要點及卸件裝置。本設(shè)計采用了沖孔—落料級進模成形墊 片 。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四個 30mm 的孔，而后利用第一步?jīng)_出?的 30mm 的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(guān)鍵詞：限位板、 壓力機、 級進模具、 沖孔、 落料Stamping process and die design of limit plankAbstract:This design topic hurtles to cut a mold for the limit plank, body now the typical model be blunt to cut design request, contents and direction of mold, there is certain design meaning.Pass the design to that molding tool, strengthenned a design to comprehension and usage which hurtles to cut the mold design foundation knowledge, for design more complicated of blunt cut a molding tool to have done cushion.This design usage is blunt to cut the foundation knowledge of craft and molding tool design, the function which analyzed a plank material first request, have done preparation for the type which selects by examinations a molding tool;Then computed to hurtle to cut a piece of blunt cut dint, easy to selection pressure machine tonnage and assurance pressure model number;Finally analyzed blunt cut the characteristic of piece, easy to assurance molding tool of design parameter, design important point and unload a device.This design adopted blunt bore-fall to anticipate class to enter a mold to take shape a mat slice.Take shape the principle can divide the line to two stages:Blunt bore convex mold rushes out 4 first with cave mold common function first the bore with 30 mms, and then make use of square one to rush out of the bore with 30 mms do an accurate fixed position to make the shape convex mold and cave mold common function to make a work piece to fall to anticipate to take shape.Keyword:The limit plank, pressure machine, class enters a molding tool, hurtle bore and fall to anticipate
