Description

汽车转向节叉立式锻造方法
技术领域 本发明涉及汽车转向系统的转向节叉零件。
背景技术 在汽车转向系统中， 转向节叉的结构由杆部、 法兰盘、 法兰盘 上对称的叉耳形成一个整体， 转向节叉通过锻造成形， 零件在毛坯制 造中， 采用卧式锻打工艺， 沿转向节叉的轴向方向（水平方向）分型， 这样由于锻打中必须存在的拔模角及飞边问题， 造成内档底部余量 大， 飞边大， 在锻打中需经过两次制坯工序才能有效地保证零件的成 形， 因而形成材料利用率低， 产品成本高。 发明内容 本发明的目的是提供一种汽车转向节叉锻造工艺方法，在保证提 供合格零件的情况下， 提高材料利用率， 以解决零件成本高的问题。 为此， 本发明的技术方案如下： 汽车转向节叉立式锻造工艺方 法， 所述的汽车转向节叉由杆部、 法兰盘、 法兰盘上对称的叉耳形成 一个整体， 其特征在于具体内容为： a、 从汽车转向节叉法兰盘、 兼 顾两侧叉耳进行立式分模， 立式分模的分模面与杆部垂直； 对汽车转 向节叉的叉耳内档进行补料， 形成拔模角； b、 然后在锻造机上进行 立式锻打成形； 所述叉耳内档底部直接锻打成形。 有益效果： 由于改变了分模形式， 对零件加工部位进行了补料， 优化了制坯工序， 实现立式锻打； 分模面积减少， 飞边减少， 提高材 料利用率 20%以上，减少卧式锻打中的二次制坯环节，提高锻造效率， 降低生产成本。所述叉耳内档底部直接锻打成形， 消除内幵档底部加 工余量。 附图说明
图 1为汽车转向节叉的结构示意图。 具体实施方式 结合图 1 所示的汽车转向节叉， 进一步描述本发明如下： 所述 的汽车转向节叉由杆部 1、 法兰盘 2、 法兰盘上对称的叉耳 4形成一 个整体。 立式锻造工艺方法的具体内容为： a、 从汽车转向节叉法兰 盘 2、 兼顾两侧叉耳 4进行立式分模， 立式分模的分模面 3与杆部垂 直： 对汽车转向节叉的叉耳内档 6进行补料， 形成拔模角； b、 然后 在锻造机上进行立式锻打成形； 所述叉耳内档底部 5直接锻打成形。
所述的拔模角一般为 2 ° 〜3 ° 。
