开篇

您的图纸决定产品规格。我们的工作就是精确按图制造,并在发货前提供验证。

系列02涵盖用于电气接触和机械固定的不锈钢触摸弹簧。我们根据您的图纸生产,而非按目录供货。每一圈弹簧均经过卷绕、热处理,并按您指定的载荷和变形量进行测试。

概览: 线径公差±0.02 mm,自由长度公差±0.05 mm。打样交期7-12天,批量生产交期15-20天。无起订量。发货前100%全检。

规格参数

我们采用CNC卷簧机和精密冲压生产线制造不锈钢触摸弹簧。下表列出标准生产能力。如果您的需求超出这些范围,请照常发送图纸——我们每周都会承接特殊定制报价。

参数能力范围
线径0.10 mm – 8.00 mm
材料SUS 301、SUS 304、SUS 316、SUS 631 (17-7PH)
卷绕工艺CNC卷簧(线径≤4.0 mm),CNC冲压成型(线径>4.0 mm)
自由长度公差±0.05 mm(标准),±0.02 mm(精密)
外径公差±0.05 mm
载荷公差工作高度处规定载荷的±3%
表面处理钝化、电解抛光或原态拉丝
热处理去应力退火或淬硬至洛氏硬度C 40–48
批量范围1件至1,000,000件
检验关键尺寸100%全检,每批次载荷测试

定制不锈钢拉伸弹簧

每根弹簧至少经过两道质量关卡:成型后一道,热处理后一道。我们在批次卡上记录实际线材批号。

客户选择向我们发送图纸的三个理由

1. 批次可追溯的质量。 每个生产批次均带有唯一批次代码。该代码关联线材证书、机器参数、热处理曲线和检验结果。如果发生现场失效,您可以精确追溯到对应线卷和操作班组。我们保存记录长达10年。

2. 每批次附带检验报告。 您无需仅凭信任。我们随每次发货附上尺寸报告和载荷测试数据。报告列出自由长度、外径和工作高度处载荷的实测值。对于关键弹簧,我们还附带三坐标测量(CMM)检测报告。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器。 您的触摸弹簧通常安装在包含冲压接触片、CNC加工外壳和散热器的组件中。当您将整个组件图纸发送给我们时,我们可在同一厂区内协调全部四道工艺。这意味着只需一份采购订单、一套质量体系、一个交货日期。供应商之间无需互相推诿。

这些零件的应用领域

凡是在反复压缩下需要可靠电气接触的场景,都会用到不锈钢触摸弹簧。常见应用包括:

  • 手持设备、电动工具和医疗监护仪中的电池触点。
  • 汽车ECU和LED照明模块中的接地夹。
  • 测试治具和连接器中的弹簧探针。
  • 薄膜开关和控制面板中的触觉反馈弹簧。
  • 需要同时具备导电性和压缩力的EMI屏蔽衬垫。

在这些应用中,弹簧在特定高度下的载荷比其自由长度更为关键。因此我们在每个批次上不仅检测尺寸,更测试载荷。

客户下单前常问的问题

问:真的没有起订量吗? 答:是的。我们打样从1件起做。批量生产时,根据线径和数量按件计价。小批量单件成本较高,因为调机时间是固定的,但您绝不会被迫订购超出需求的数量。

问:你们如何控制公差和质量? 答:我们使用带闭环送线控制的CNC卷簧机。成型后,弹簧通过载荷测试机验证在您指定高度下的力值。尺寸检测使用数显千分尺和光学投影仪。每批发货均附带批次检验报告。

问:定制弹簧的交期是多久? 答:图纸确认后,打样产品7-12个工作日内发货。批量生产需15-20个工作日,具体取决于数量和热处理要求。如有紧急需求,我们可以分批发货——先发首批10%以保障您的生产线不停顿。

问:你们能提供材质证明吗? 答:可以。每批线材均附带钢厂材质证明,显示化学成分和力学性能。我们会将副本附在批次卡上并纳入发货文件。对于SUS 316或17-7PH材料,我们还可根据要求提供腐蚀测试报告。

发送您的图纸

将您的PDF或STEP文件发送至 sc@bquq.com。请注明材料牌号、载荷要求和任何表面处理说明。您将在12小时内收到正式报价——不是估算,不是区间,而是包含交货日期的确定价格。

更倾向于电话沟通?请通过WhatsApp联系我们:+86 13713157787。北京时间周一至周六,我们在一个工作小时内回复。

精密制造的本质是消除不确定性。将您的图纸发送给我们,我们将向您展示这在实践中意味着什么。
