汽车发动机生产过程中,对于缸体周围壁体的结构稳定有着严格的控制。在使用较为广泛的V22缸体中,对于铸造的上表面在热源升高的过程中会出现裂缝,随着温度不断升高,裂缝也相应增大,在缸体周围设置的散热网片进行架设使得排气口温度降低,利用冷铁的处理工艺,在根据实际的操作模式下得出V22缸体利用冷铁处理的方式将覆盖面的热量降低20%,同时在散热系统的帮助下改良缸体的裂纹情况,最终达到缸体局部热节的温度控制和缸体自身的稳定性。
In the process of automobile engine production, there is strict control over the structural stability of the wall body around the cylinder body. In the more widely used V22 cylinder, cracks will appear on the upper surface of the casting when the heat source is raised. As the temperature rises, the cracks will increase correspondingly, and the cooling net disposed around the cylinder body will be erected Making the exhaust port temperature decreased, the use of cold iron processing technology, based on the actual operating mode of V22 cylinder using cold iron treatment will cover the heat reduced by 20%, while the cooling system with the help of improved cylinder Of the crack situation, and ultimately reach the cylinder heat section temperature control and the stability of the cylinder itself.
