                              汽车制动卡钳的铸造工艺及其改进分析

                              时间:2020-04-20 16:04作者:曼切
                              本文导读:这是一篇关于汽车制动卡钳的铸造工艺及其改进分析的文章,铸造是保证汽车制动卡钳质量的重要途径,要在剖析制动卡钳故障问题基础上探索铸造的新思路、新方法,在改进铸造工艺的过程中保证汽车制动卡钳质量,能够在恶劣的工作环境中高效运转,将故障发生系数以及应用成本最小

                                摘    要: 制动卡钳是汽车制动系统必不可少的组成要素,工作时会受到较大的冲击振动荷载,在力学性能方面有着较高的要求,而这离不开合理化的铸造。因此,本文从不同角度入手客观阐述了汽车制动卡钳的铸造工艺,在有效的铸造过程中提高汽车制动卡钳整体性能以及运行效率。

                                (一)改进浇注系统

                                就该汽车制动卡钳来说,在原始铸造工艺作用下,冒口尺寸以及冒口颈横截面积都太小,铁水流动性以及补缩效果不高,铸件两端以及底部极易出现缩孔缩松情况,需要在具体分析缺陷问题的基础上立足铸造实际情况,科学改进对应的浇注系统。汽车制动卡钳的冒口是改进中不可忽视的一大关键点,可以将独立设在铸件两端的冒口改为共用的冒口,将其设置铸件合理位置,解决冒口颈横截面积太小的问题,将直浇道窝设在直浇道底部,有效控制铁水下流中产生的动能,也在一定程度上缩短铁水高速紊流区,确保在铸造过程中铸件能够被铁水顺利充满,在源头上将缩孔缩松缺陷问题的发生系数最小化。此外,在浇注系统改进过程中,要注重充型温度,充型完成时的温度范围为1271到1420摄氏度[3],有效控制温度的同时提高充型的平稳性,为铸件顺利凝固提供重要保障。针对铸件底部出现的缩孔缩松问题,可以在改进浇注系统过程中对砂芯进行合理化处理,规范化放置外冷铁,在解决铸件缩孔缩松这一缺陷问题的基础上最大化提高汽车制动卡钳的机械性能。
