这是BQUQ冲压电缆夹及导管夹系列——涵盖单耳、双耳和马鞍式夹子,全部在25吨至80吨高速冲床上成型。您在安装孔上可获得±0.05毫米的稳定平整度,回弹补偿后的折弯角度为±0.5°,外圆角表面光洁度为Ra 1.6 µm。标准尺寸的典型交货期为12个工作日;定制模具需增加7天。所有零件均在中国制造,采用连续退火带材,可选镀锌镍处理,通过72小时中性盐雾试验。

我们的级进模如何在耳部保持±0.05毫米公差

本系列中的每个夹子均在6至10工位的单套级进模中生产。先冲导正孔,然后通过凸轮驱动顶料器成型耳部,以防止回弹。这一工序将关键耳高锁定在±0.05毫米,从而确保您的线束不会产生异响。我们不采用二次折弯工序——这正是大多数冲压厂失去公差精度的环节。我们的模具维护周期为每50,000次冲程一次,实测冲头磨损极限为0.02毫米,超过即需重新刃磨。

带材材料选项及可指定的硬度

您不会被限制在单一金属上。本系列我们使用三种基础材料:304不锈钢(硬度最高80 HRB)、65Mn弹簧钢(淬火至40–45 HRC)和6061-T6铝(硬度95 HB)。对于高张力导管夹,65Mn选项在冲压前进行预回火处理,因此最终夹子在10,000次插入循环后仍能保持夹持力。如果您需要导电性,我们提供镀锡铜带(C11000),锡层厚度5 µm,接触电阻保持在0.5 mΩ以下。

可承受72小时盐雾试验的表面处理及电镀

冲压毛边通过振动研磨机去毛刺,最大圆角半径0.05毫米。然后我们提供三种表面处理之一:透明镀锌(厚度8 µm,72小时盐雾试验)、黄锌(12 µm,96小时)或发黑处理(适用于弹簧钢,48小时)。对于户外导管夹,我们推荐黄锌选项——每件成本增加$0.02,但耐腐蚀性提高一倍。如果您的装配线使用电泳涂装,我们还提供涂装前的磷化底层。

每批导管夹的夹持力测试

我们不仅检查尺寸。每批1,000件产品均需在液压拉力测试机上进行夹持力测试。夹子必须能夹持8毫米导管,标准尺寸的最小轴向拔出力为45 N,重型系列为70 N。测试夹具记录峰值力和0.5毫米位移量。如果五个样品的平均值低于规格要求,整批产品将被拒收并返工。此结果记录在您的批次追溯报告中。

适用于您装配线的包装和标签

夹子采用防静电塑料托盘独立分格包装——不会缠绕在一起。每个托盘可装200件,每个纸箱装10个托盘。我们打印标签,包含您的零件号、我们的批号、材料炉号和日期代码。如果您使用自动化贴片机,我们可以将较小夹子(宽度最大20毫米)按4毫米间距卷装到330毫米卷盘上。这消除了您生产线上的手动分拣工序。

每次发货前检验——高度规和三坐标测量机

在纸箱封箱前,我们使用分辨率为0.5 µm的三坐标测量机(CMM)进行最终检验。我们检查耳高、导管开口内径和安装片的平整度。在2倍放大下进行目视检查,以发现任何毛刺或模具痕迹。每次发货您都会收到一份合格证书,列出该批次的实际测量值,而不仅仅是标称值。

我们与普通冲压厂的区别

大多数工厂报价±0.1毫米公差就算完事。我们将公差控制在±0.05毫米,因为我们的模具使用坐标磨床而非平面磨床进行研磨。我们还使用冲程深度可编程至0.01毫米的伺服冲床,因此长时间生产中折弯角度不会漂移。如果您需要比±0.05毫米更严格的公差,我们可以增加精压工位——这可将公差提升至±0.02毫米,但模具成本增加15%。如需深入了解我们如何为模具加工选择切削刀具,请参阅我们的CNC切削刀具选型指南。如果您正在设计配套支架,请查阅我们的CNC加工公差指南,以确保孔位匹配。

如何确保夹持力的一致性?

我们每1,000件抽取5个样品进行拉力测试;如果力值低于规格要求,整批产品将被拒收,并检查模具磨损情况。

重复订单的交货期是多久?

图纸无变更的重复订单在10个工作日内发货,我们会在模具库中为您保存模具长达5年。

请发送您的图纸,我们将在12小时内提供正式报价。发送邮件至sc@bquq.com或WhatsApp +86 13713157787。附上PDF或STEP文件——我们的工程师将在您确认前核实模具工位和电镀成本。
