这些接头在您的装配线中替代什么

这些CNC加工的不锈钢接头和连接器是精密加工的替代品,用于替代标准气动、液压和传感器安装接头。我们提供±0.005毫米的位置公差,密封面0.008毫米的真实跳动,以及热处理后48 HRC的表面硬度。标准批次交货期为15个工作日,原型件为7天。这不是目录零件——每个尺寸都按照您的图纸加工,而非分销商的库存清单。

为什么304L和316L对腐蚀性介质至关重要

我们使用304L加工一般空气和水管接头,使用316L加工化工、海水和制药冲洗环境。L级意味着更低的碳含量(最大0.03%),可防止焊缝处铬碳化物析出。对于高磨损的快插接头本体,我们指定17-4 PH不锈钢,时效处理至44-48 HRC。该硬度可抵抗螺纹端的磨损,使您的连接器能够承受500次以上的插拔循环而不卡死。

我们内部加工的螺纹类型:NPT、BSPP、BSPT、公制

我们使用单点刀片在CNC车床上加工所有螺纹类型,而非丝锥。这使您的中径控制在6H/6g公差等级内。对于NPT和BSPT锥管螺纹,我们使用螺纹塞规在基准线处测量中径,并将数值记录在每份证书上。对于端面密封连接器(ORFS、JIC 37°),我们将座面角度加工至37°±0.5°,并抛光至Ra 0.4 µm,确保在300 bar压力下实现无气泡密封。无螺纹滚压,无二次攻丝——一次装夹,一条公差链。

密封面跳动控制:0.008毫米或更小

接头上的密封面是泄漏发生的地方。我们将密封面与螺纹中径之间的总指示跳动(TIR)控制在0.008毫米。这是典型航空航天接头公差的一半。我们通过在5轴铣车复合机床上同一次夹紧操作中加工螺纹和端面来实现这一点。我们不会切断后重新装夹。如果您的设计需要六角本体,我们在车削后拉削六角,然后重新切削端面以消除夹紧引起的变形。

我们如何避免交叉钻孔端口上的毛刺

交叉钻孔端口(例如,一个2毫米的感应端口与10毫米的孔相交)是接头常见的失效点。交叉处的毛刺脱落会污染您的系统。我们首先钻交叉端口,然后其次镗削主孔。镗刀会去除交叉处的毛刺。加工后,我们用0.3毫米的尼龙刷清洁每个端口。对于医疗或半导体接头,我们增加30分钟的陶瓷介质滚磨工艺,使所有内表面达到均匀的Ra 0.8 µm。这是标准工艺,而非额外收费选项。

每次发货前的检测:CMM和气动量仪

每批CNC加工的不锈钢接头和连接器都会附带完整的尺寸报告。我们使用蔡司CMM检测位置公差,使用三丰气动量仪检测孔径(重复性±0.001毫米),并为每种螺纹形式配备螺纹塞规组。我们不进行抽样检测——我们对首件进行100%关键尺寸检测,然后对剩余批次进行30%全尺寸检测。报告会随发货确认一起通过电子邮件发送给您。如果某个尺寸超差,该零件将被报废,而非返工。

无起订量,标准接头本体无设置费

我们在刀具库中储备了常见接头本体(直通、弯头、三通、四通)的刀具。这意味着您的第一件与第500件价格相同——无设置费,无最小起订量。您可以订购一个原型连接器来测试密封设计,我们将在7天内发货。对于具有非标准六角或端口角度的定制本体,需支付150美元的一次性编程费,但起订量仍为零。这是中国制造的精密加工,但具有本地加工车间的响应速度。

你们接受单件订单吗?

是的——我们没有起订量。单件也会被加工、检测,并附完整的CMM报告发货。

你们能匹配我现有库存中的螺纹形式吗?

将样品或带有螺纹标识的图纸发送给我们,我们将加工出相同中径等级的配合零件。

你们对密封面进行哪些质量控制?

我们使用0.001毫米千分表在精密旋转工作台上测量TIR,并对所有直径大于6毫米的孔进行气动量仪检测。

定制接头的最快交货期是多少?

对于简单的六角本体(一个螺纹和一个孔),如果您当天批准DXF文件,我们可以在5个工作日内发货。

如何为您的接头选择合适的刀具

如果您在内部加工接头,螺纹质量取决于刀具选择。我们的工程师在我们的CNC刀具选择指南中详细介绍了不锈钢加工的刀片几何形状和切削速度。关于公差定义,请在发送图纸前参阅我们的CNC加工公差指南

将您的图纸以STEP或DXF格式发送给我们。我们将在12小时内回复固定报价——包括材料成本、加工时间、热处理和检测报告模板。发送邮件至sc@bquq.com,或通过WhatsApp联系+86 13713157787。附上图纸,我们将立即开始DFM检查。无起订量,无隐藏刀具费用,无意外。
