这是BQUQ不锈钢螺旋压缩弹簧系列:采用302、316、17-7PH和Inconel X-750材料定制制造的螺旋弹簧,在中国通过CNC卷绕和全研磨工艺生产。您获得的弹簧外径公差为±0.01 mm,自由长度公差为±0.5%,最大工作硬度为72 HRC(适用于17-7PH)——原型标准交期为7天,批量生产为15天。无最小起订量,您可以订购一件或一百万件。

我们如何将自由长度和载荷控制在±0.5%以内

大多数弹簧失效源于自由长度不一致和载荷漂移。我们的CNC卷绕机采用闭环送线系统,每0.1秒进行激光测量。这使线径0.1 mm至12 mm的弹簧自由长度公差保持在±0.5%。50%压缩量下的载荷保持在您指定值的±3%以内。我们使用数字测力仪对每批产品进行验证——不是抽样,而是每件弹簧。

我们使用的耐腐蚀和抗疲劳材料及热处理工艺

我们从认证线材开始:AISI 302(基本耐腐蚀性)、AISI 316(海洋和化工环境)、17-7PH(沉淀硬化后最大硬度72 HRC的高强度材料)以及Inconel X-750(可连续工作至600°C)。每个弹簧根据材料不同,在260–430°C下进行去应力热处理。对于17-7PH,我们额外在480°C下进行1小时的沉淀硬化循环。这确保您的弹簧在循环载荷下不会松弛——已通过最大应力80%条件下1,000,000次循环测试。

表面处理和端部研磨:Ra 0.4和方形端面

粗糙边缘会导致应力集中和过早断裂。我们将两端研磨平整,端面与轴线的垂直度偏差在0.5°以内。研磨端面的表面粗糙度为Ra 0.4 µm。弹簧体表面可选择钝化处理(Ra 0.8)或电解抛光(Ra 0.4)。电解抛光去除0.002–0.005 mm的表面层,消除拉丝产生的微裂纹。如果您需要医疗或半导体用途的特定表面处理,请告知我们——我们有8种表面处理选项。

定制端部:闭合端、开口端、研磨端或猪尾端

标准弹簧采用闭合研磨端。但您的应用可能需要其他类型。我们制造用于动态载荷的开口端、用于静态压缩的闭合端以及用于弹簧导杆的猪尾端。我们还提供缩径外径端(适用于紧凑孔径)和锥形弹簧(每圈嵌套在下一圈内)。我们的工程师会根据您的载荷方向和空间限制建议端部类型——建议服务不收取额外费用。

每次发货前检验:100%尺寸检查

我们不发送随机样品。每件弹簧都使用视觉测量系统(精度±0.002 mm)测量自由长度、外径和线径。每批5%的弹簧使用5 kN万能试验机进行载荷测试。材料证书来自钢厂,包含化学成分和抗拉强度。如果您订购超过5,000件,我们将提供包含批次分布直方图的完整检验报告。这是标准服务,不是付费附加项。

出口包装和防腐蚀保护

不锈钢在盐雾或潮湿环境下仍会腐蚀。我们为弹簧轻涂润滑油(或使用干膜润滑剂用于洁净室环境),并用防静电袋和VCI(气相防锈)纸包装。出口时使用抗压强度15 kg的双层纸箱。如果您需要单个塑料袋包装或用于装配线的色标托盘,我们免费提供。每个箱子都贴有标签,标明您的零件号、批号和炉号。

我们的CNC加工如何支撑弹簧精度

仅靠弹簧本身无法解决装配问题。如果您的弹簧安装在机加工孔内或轴上,公差必须匹配。我们的内部CNC加工中心(20台设备,4轴和5轴)可以生产公差同样为±0.01 mm的配合零件。这意味着您可以从同一工厂获得完整组件——弹簧和壳体。有关影响弹簧性能的切削刀具几何参数,请参阅我们的CNC切削刀具选择指南。有关一般公差叠加,请阅读我们的CNC加工公差指南

可以。请将实物样品或包含外径、内径、自由长度、线径和指定高度载荷的图纸发送给我们——我们将进行逆向工程,生产出达到或超过原始规格的弹簧。

你们如何确保中国制造弹簧的质量?

我们对每件产品进行100%尺寸检验,每批5%进行载荷测试,并提供包含化学成分和抗拉强度的材料证书。我们的质量控制流程遵循ISO 9001:2015标准。

定制弹簧订单的典型交期是多久?

图纸确认后,原型在7天内发货。批量生产(最多10,000件)在15天内发货。对于紧急需求,原型可加急至3天,需加收10%费用。
