Description
一种气动内外牙接头毛胚的制造工艺技术领域[0001] 本发明涉及一种气动内外牙接头毛胚的制造工艺领域。背景技术[0002] 气动内外牙接头毛胚是快速接头上的一个重要配件，因为不需要工具就能实现管路连通或断开快速接头在人们日常生活中被普遍使用，随着快速接头的需求量越来越大， 市场对快速接头相关配套零部件产品的需求量及质量的大幅提高，目前国内对此产品制造多采用断料、车修的加工方式，其工艺设备以及产品的各项综合性能无法满足国内外市场的要求，其生产不仅浪费材料，而且工序繁杂、加工难度大、效率低，质量也得不到相应的保证。发明内容[0003] 本发明要解决的技术问题是提供一种气动内外牙接头毛胚的制造工艺，采用冷镦机一次成型，在加工过程中原材料几乎无损失，不仅节省了原材料、降低成本、提高生产效率及产品的机械性能，而且精度高确保了产品的质量。[0004] 为解决上述问题，本发明的技术方案如下：[0005] 一种气动内外牙接头毛胚的制造工艺，将钢坯原料制成盘圆料，然后对盘圆料进行磷酸盐表面处理，再将粗抽后的盘圆料分别经过球化退火、磷酸盐皮膜处理、精抽定径处理，最后在冷镦成型机内进行气动内外牙接头毛胚的成型工序，具体包括以下步骤：[0006] (I)、将精抽定径后的盘圆料于冷镦机内自动剪切成单个的气动内外牙接头毛坯件；[0007] (2)、利用机械夹具夹持将所述的气动内外牙接头毛坯件，送到冷挤压模具的一号模模口，由一号模的冲具将气动内外牙接头坯件顶入凹模内，由于凹模后端顶堵有顶杆，凹模底部的内壁有倒角，在冲具施加压力的挤压下，将气动内外牙接头坯件镦挤压成带有圆角的六角形状并镦平，同时镦出内倒角；[0008] (3)、将一号模成型后的气动内外牙接头坯件利用机械夹具翻转到二号模模口，由二号模的冲具将气动内外牙接头坯件顶入凹模内，由于冲具前端有凸起台阶，在冲具施加压力的挤压下，在气动内外牙接头坯件前端面镦出第一定位孔，并且镦出内倒角；[0009] (4)、将二号模成型后的气动内外牙接头坯件利用机械夹具横移到三号模模口，由冲具将气动内外牙接头坯件顶入凹模内，由于顶杆前端有凸起锥体，气动内外牙接头坯件上的第一定位孔与冲具前端凸起锥体配合，在冲具施加压力的挤压下，将气动内外牙接头坯件前端面冲出第一沉孔；[0010] (5)、将三号模成型后的气动内外牙接头坯件利用机械夹具自动翻转到四号模模口，由冲具将气动内外牙接头坯件顶入凹模内，气动内外牙接头坯件上的第一沉孔与凹模内顶杆的凸起锥体配合，冲具前端有凸起台阶，在冲具施加压力挤压下，将气动内外牙接头毛胚前端带有圆角的六角形状挤压成倾角的六角形状，并镦出第二定位孔；[0011] ¢)、将四号模成型后的气动内外牙接头坯件利用机械夹具自动横移到五号模模口，由冲具将气动内外牙接头坯件顶入凹模内，气动内外牙接头坯件上的第一沉孔与凹模内顶杆的凸起锥体配合，冲具前端凸起锥体与第二定位孔配合，在冲具施加压力的挤压下，将气动内外牙接头坯件前端面冲出第二沉孔；
[0012] (7)、将五号模成型后的气动内外牙接头坯件利用机械夹具自动翻转到六号模模口，由冲具将气动内外牙接头坯件 顶入凹模内，同时用凹模内顶杆的凸起锥体与第二沉孔配合直接穿过气动内外牙接头坯件的第一沉孔将残留铁屑通出，制成最终成型的气动内外牙接头毛胚。
[0013] 与已有技术相比，本发明的有益效果如下：
[0014] (I)、本发明主要利用冷挤压的方法，利用金属塑性变形的原理，在常温下对挤压模具腔内的金属施加强大的压力，使之从模孔或凹凸模的间隙中挤出，在不破坏金属性质的前提下使金属体积作塑性变形，从而获得所需零件的一种少切削或无切削的加工方式，且容易实现机械化和自动化生产；
[0015] (2)、气动内外牙接头坯件的表面经过处理和润滑，以及成型过程工艺方案及模具设计上的控制，利用多功位成型冷挤压模具的六模六冲分担产品变形过程中产生的变形抗力及模具承载能力，并利用机械夹具使坯件可连续成型不间断的特点，直接通过六模六冲成型出气动内外牙接头坯件，使其生产速度可达每分钟70-80只；
[0016] (3)、本发明采用冷挤压的方法制造，使得坯件的耗材量大幅下降，材料利用率达95%，且经过冷挤压得材料组织结构更加紧密，抗拉、屈服、伸长、冲击各项机械性能都优于机加工，确保了产品质量。
