支架沖壓工藝及模具設(shè)計(jì)
摘要
本設(shè)計(jì)題目為Z形彎曲模設(shè)計(jì)，體現(xiàn)了典型Z形彎曲模的設(shè)計(jì)要求、內(nèi)容及方向，有一定的設(shè)計(jì)意義。通過對(duì)該零件模具的設(shè)計(jì)，進(jìn)一步加強(qiáng)了設(shè)計(jì)者對(duì)彎曲模設(shè)計(jì)的基礎(chǔ)知識(shí)的了解與掌握，為設(shè)計(jì)更復(fù)雜的彎曲模具做好了鋪墊和吸取了更深刻的經(jīng)驗(yàn)。
本設(shè)計(jì)運(yùn)用彎曲成型工藝及模具設(shè)計(jì)的基礎(chǔ)知識(shí)，首先分析了板材的性能要求，為選取模具的類型做好了準(zhǔn)備；然后計(jì)算了彎曲件的彎曲力，便于選取壓力機(jī)噸位及確定壓力機(jī)型號(hào)；最后分析了彎曲件的特征，確定模具的設(shè)計(jì)參數(shù)、設(shè)計(jì)要點(diǎn)及頂出裝置的選取。
本設(shè)計(jì)采用了組合上下模成型Z形件，這種結(jié)構(gòu)能有效的防止坯料的偏移，成形機(jī)構(gòu)動(dòng)作靈活可靠，設(shè)計(jì)方便，非常適合在本副模具中使用。

Piank flection of models the foundation and the moiding tool desing
Abstract
This design topic is a Z form flection the mold design, body now the typical model Z form flection mold of the design request,contents and direction, there is certain design meaning.Foundation knowledge passed the design to the spare parts' molding tool, strengthenned the design flection a mold a design further, for design a more complicated bent molding tool to have done cushion and absorbed deeper experience.
This design usage flection models the foundation knowledge of the craft and the molding tool design, analyzing the function request of the plank material first, having done preparation for the type that selects by examinations a molding tool;Then compute the bent dint of the bent piece, the easy to selection pressure machine tonnage and make sure pressure model number;Analyzed the characteristic of the bent piece finally, make sure the design parameter of the molding tool and design the important point and crest selection for equip.
This design adopted the combination top and bottom mold to model a Z form piece, this kind of structure can keep from anticipate effectively of be partial to move, take shape organization to act vivid credibility, design convenience, suit to use in this vice- molding tool very much.
Keywords:Bent mold; composite punch; composite die
