Description

一种螺旋锥齿轮主动齿车螺纹加工工艺
技术领域
本发明涉及机械加工技术领域,具体为一种螺旋锥齿轮主动齿车螺纹加工工艺。
背景技术
传统的汽车主减速器螺旋锥齿轮螺纹加工工艺有两种,一种是对工件热处理前加工螺纹,热处理后对螺纹进行修整;另一种是在工件上先车出螺纹,热处理后再进行螺纹磨削,在磨削的过程中需要添加磨削油,这样废油就会对环境造成污染。采用第一种的方式加工螺纹,其工艺复杂,效率低下,且在没有经过热处理时就形成螺纹,由于螺纹硬度低,在产品的流转过程中极易形成磕碰伤,此工艺生产的螺纹经过热处理的修整后,外观的质量较差,而采用第二种加工工艺,则加工时间较长,效率低且成本高,对环境的污染较大。为此,我们提出了一种螺旋锥齿轮主动齿车螺纹加工工艺投入使用,以解决上述问题。
发明内容
本发明的目的在于提供一种螺旋锥齿轮主动齿车螺纹加工工艺,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种螺旋锥齿轮主动齿车螺纹加工工艺,该加工工艺具体包括以下步骤:
S1:按照设计要求,将金属坯料放入锻压机械工作区域中,将金属坯料锻造冲压成具有一定机械性能、一定形状和尺寸的锥齿轮锻造件;
S2:对锻造件进行正火处理,使其硬度HB达到180--240之间,随后再进行退火处理;
S3:退火后的锻造件再加热到500--650℃,保温3--4h,随后自然冷却至室温;
S4:将锻造件置入盛有活性炭介质的容器中,再加热至900--980℃,保温6--7h后,使渗碳介质分解出的活性炭原子渗入锻造件的表层,以增强其表面硬度和耐磨度;
S5:待锥齿轮锻造件冷却后,随后将锥齿轮锻造件固定在车床的固定夹具上,利用铣刀对锥齿轮锻造件表面进行车螺纹加工;
S6:对表面形成螺纹的锥齿轮锻造件进行螺纹研磨,修正螺纹的螺距,提高螺距的精度;
S7:在锥齿轮的螺纹槽处进行电镀处理,随后用涂抹防锈油并用塑料薄膜包裹。
优选的,所述步骤S2中,将锻造件加热到900--1000℃,并保温3--4h。
优选的,所述步骤S4中,渗碳处理过程中采用井式炉对锻造件进行加热,锻造件表面形成的碳层厚度在1--1.5mm。
优选的,所述步骤S4中,渗碳处理在氮气保护气氛下进行,其在渗碳处理前要清除锥齿轮锻造件的表面杂质。
优选的,所述步骤S6中,螺纹研磨采用铸铁制作的螺母型研磨轮进行,同时研磨轮具备正反转的功能。
优选的,所述步骤S7中,电镀处理采用热浸镀锌工艺,即将锥齿轮浸没在温度500--600℃的融化锌溶液中,在锥齿轮的表面形成一层1--2mm厚的镀锌层。
与现有技术相比,本发明的有益效果是:本发明通过对工件表面进行正火以及高温回火,增加工件的硬度以及耐磨度,在车螺纹后通过铸铁等软性材料对螺纹槽进行研磨,提高螺距的精度,最后采用镀锌工艺使锥齿轮表面形成保护层,延长锥齿轮的使用寿命。
