设计简介
摘 要
本次 设计包括编写汽车转向节锻造加工工艺规程和设计锻造模具，是对我四年本科学习的一次考察，也是自己运用所学知识进行实践的一次好机会。该次设计，完成了轻型卡车转向节锻造的工艺流程安排、工艺编制及锻造模具设计的技术说明，制件的材料是40Cr.
转向节锻造的工艺设计，完成的是材料的自由锻制坯、模锻锤预锻和终锻、切边压力机切边工艺。本文首先对产品图及成型工艺特点进行了分析，确定采用电液模锻锤进行锻造，使用带有预锻型槽和终锻型槽的模具机型终锻的工艺方法，根据零件的尺寸形状确定了加工面的预留加工余量、根据材料查表确定了加热温度、始锻温度、终锻温度，确定了锻件重量、进行了锻造力的估算，并根据锻造打击力进行了锻造设备的选择、对切边模具的凸模，凹模刃口尺寸进行了计算，最后利用CAD软件按工程制图标准画出锻造工步图、锻造胎模图、锻造模具图、切边模具图，编制了完整的锻造工艺。

ABSTRACT
The graduation design including compilation automotive steering knuckle forging process planning and design for forging die of undergraduate study four years, but also his trip knowledge learned a good oppotunity to carry on the practice. The Times design, completed the light trucks steering knuckle forging process arrangement, process Compilation and forging die design technical specification, the product's material is 40Cr.
Steering knuckle forging process design, complete is material of free forging blocking, forging hammer forging and eventually gets forging, trimming press trimming process. This paper firstly product image and molding process characteristics are analyzed, sure to use electro-hydraulic forging hammer forging, use with pretensioners on forging type slots and end the mould forging type slot machine forging process method, end according to determine the size of parts machining surface shape to reserve machining allowance, according to materials look-up table determined the heating temperature, temperature, final forging beginning temperature of forging, determines the weight of the forging of forgings, according to the estimate, and force the forging stroke forging equipment choice, the punch molds for trimming blade, concave die size, finally, using the calculated according to the engineering drawing standards CAD tools software draw forging tool graph, forging die step womb graph, forging die figure, trimming mould figure, compiled the complete forging process.
Keywords: Free Forging Blocking; Tire Mold; Machining Allowance; The Blade Size Calculation; Forging; Eventually Gets Forging; Forging Work Steps
