摘   要
 汽車電機(jī)爪極是汽車電機(jī)的關(guān)鍵部件, 一般采用傳統(tǒng)的鑄造工藝，工步繁多，性能較低，研究新型工藝進(jìn)行加工，降低成本，對(duì)提高質(zhì)量有著重要的意義。
 本文對(duì)汽車電機(jī)爪極采用液態(tài)模鍛工藝。經(jīng)過(guò)對(duì)該零件工藝分析和計(jì)算，確定合理的液態(tài)模鍛工藝方案，設(shè)計(jì)出液態(tài)模鍛工序的整套模具，使用UG,AutoCAD等繪圖軟件繪制模具零件圖和裝配圖。
 通過(guò)對(duì)汽車爪極模具設(shè)計(jì)，鞏固和深化了所學(xué)知識(shí)，取得了比較滿意的效果，達(dá)到了預(yù)期的設(shè)計(jì)意圖。

Squeeze Casting Design of Automotive Longitudinal Beam

Abstract
 Automotive Claw mold design and manufacturing is the critical part of the automotive industry, and the traditional casting process owns complex mold and various steps. research new technology for processing, reduce costs and improve product quality.
 In this paper, automotive Claw using squeeze casting process. After analysis of the components and calculation process to determine a reasonable scheme of squeeze casting process. design a complete set of mold of squeeze casting craftwork and use UGAutoCAD and other graphics software to draw maps and mold parts,
 By designing the automotive ,the author has strengthened and deepened those learned knowledge and acquired very pleasant result, also achieved the expected intention of designing.
