【摘要】：側(cè)圍外板是汽車的核心外覆蓋件,其特點(diǎn)是形狀復(fù)雜、工序內(nèi)容繁多且零件的表面質(zhì)量和尺寸精度要求較高。通過側(cè)圍外板的沖壓工藝方案分析,提出一種帶雙壓料的側(cè)整形工藝和結(jié)構(gòu),可以有效解決整形起皺和回彈,同時(shí)達(dá)到保證A面質(zhì)量的目的。重點(diǎn)介紹了側(cè)圍整形模結(jié)構(gòu)、雙壓料側(cè)整形機(jī)構(gòu)的設(shè)計(jì)要點(diǎn)及工作原理,完成了側(cè)圍外板緊湊合理的側(cè)整形模具結(jié)構(gòu)設(shè)計(jì)。實(shí)際生產(chǎn)表明,該側(cè)整形模具可有效解決整形起皺、回彈難題,提高零件成形質(zhì)量,提升A面品質(zhì),縮短調(diào)試周期,降低工裝開發(fā)成本。
[Abstract]:The side outer panel is the core outer panel of automobile, which is characterized by complex shape, various working procedures and high surface quality and dimension precision of the parts. Based on the analysis of the stamping process scheme of the side outer plate, a kind of side shaping technology and structure with double pressing material is put forward, which can effectively solve the problem of wrinkling and springback, and achieve the goal of ensuring the quality of the A face at the same time. This paper mainly introduces the structure of the side-girth shaping die, the design essentials and the working principle of the double-press side-shaping mechanism, and completes the design of the compact and reasonable side-shaping die structure of the side-girth outer plate. The practical production shows that the side shaping die can effectively solve the problems of wrinkling and springback, improve the forming quality of parts, improve the quality of face A, shorten the debugging period, and reduce the cost of tool development.
