公制UNC/UNF和NPT管螺纹的螺纹尺寸、攻丝钻头、过孔和钻头

螺纹和攻丝钻 API FAQs

在您所需的螺纹百分比(默认75%)的理想孔附近的标准钻头,以及在另一系统中最接近的钻头。每个钻头都附带它实际提供的螺纹百分比,并且/tapdrill列出了从50%到90%的每个钻头,以供您选择

没有 主要 牙距 和 次要 直径 是根据基本的 螺纹 轮廓 公式 为每个 请求 计算的 所以 非标准 牙距 (M6x0.5) 也可以 使用 并 被 标记 为 标准:错误

还没有:尺寸是基本大小。标识中写的类别被接受并被忽略

最小标准孔位于或超过螺钉直径的2%(紧密)、6%(常规)或12%(松动),最小值较小。公制孔遵循标准的紧密、常规和松动系列

不 每个调用都在内存中计算 并且没有任何日志记录

是的,NPT锥形管螺纹尺寸从1/16到2英寸(获取/npt/{size}):的螺距直径、长度和螺纹高度根据锥形管螺纹公式计算。不包括干密封NPTF、直螺纹NPS和英制BSP螺纹。不适用于气体、压力或其他安全关键工作

管螺纹攻钻是车间实践,不属于标准,图表的尺寸差异为一号尺寸 API给出的是在手紧平面下小直径下的最大钻头(大多数图表显示的尺寸,1/2 NPT为23/32)以及在螺纹的细端(一号小,11/16,是在锥形铰刀之前的起始尺寸)

每个端点返回有关螺纹尺寸、攻丝钻头、间隙孔和钻头的详细信息。例如 GET /thread 端点提供大直径、螺距和小直径,而 GET /tapdrill 端点根据螺纹规格提供推荐的钻头尺寸

关键字段包括“名称”、“系统”、“公称直径”、“螺距”和“标准”。对于攻牙钻的响应,像“推荐”、“理想直径”和“线程百分比”这样的字段对于理解钻头尺寸建议至关重要

参数因终端不同而异 例如 GET /thread 接受 "designation" 来指定螺纹类型 而 GET /tapdrill 需要 "percentRequested" 来定义所需的螺纹嵌合百分比 用户还可以按 "system" 和 "series" 进行过滤

响应数据采用JSON格式结构化,以便清晰展示。例如“线程”对象包含“公称直径”和“螺距”等详细信息,而“攻钻”对象包含“推荐”钻头尺寸及其规格

每个端点提供特定信息:GET /thread 提供螺纹尺寸 GET /tapdrill 给出钻孔大小建议 GET /clearance 提供过孔尺寸 NPT 端点详细说明管螺纹尺寸和攻丝指南

用户可以通过指定参数来定制请求,例如线程的“指定名称”、钻头的“请求百分比”或NPT线程的“尺寸”。这允许根据特定需求或标准进行量身定制的响应

典型的用例包括为丝攻应用选择合适的钻孔尺寸 确定紧固件的间隙孔尺寸 以及参考管道螺纹规格用于管道工程 工程师和机械师经常使用这些数据

数据准确性通过基于既定线程轮廓公式的计算来保持 每个请求生成实时计算 确保尺寸反映当前标准和实践 而不是依赖静态图表

一般常见问题

Zyla API Hub 就像一个大型 API 商店,您可以在一个地方找到数千个 API。我们还为所有 API 提供专门支持和实时监控。注册后,您可以选择要使用的 API。请记住,每个 API 都需要自己的订阅。但如果您订阅多个 API,您将为所有这些 API 使用相同的密钥,使事情变得更简单。
价格以 USD(美元)、EUR(欧元)、CAD(加元)、AUD(澳元)和 GBP(英镑)列出。我们接受所有主要的借记卡和信用卡。我们的支付系统使用最新的安全技术,由 Stripe 提供支持,Stripe 是世界上最可靠的支付公司之一。如果您在使用卡片付款时遇到任何问题,请通过 [email protected]

此外,如果您已经以这些货币中的任何一种(USD、EUR、CAD、AUD、GBP)拥有有效订阅,该货币将保留用于后续订阅。只要您没有任何有效订阅,您可以随时更改货币。
定价页面上显示的本地货币基于您 IP 地址的国家/地区,仅供参考。实际价格以 USD(美元)为单位。当您付款时,即使您在我们的网站上看到以本地货币显示的等值金额,您的卡片对账单上也会以美元显示费用。这意味着您不能直接使用本地货币付款。
有时,银行可能会因其欺诈保护设置而拒绝收费。我们建议您首先联系您的银行,检查他们是否阻止了我们的收费。此外,您可以访问账单门户并更改关联的卡片以进行付款。如果这些方法不起作用并且您需要进一步帮助,请通过 [email protected]
价格由月度或年度订阅决定,具体取决于所选计划。
API 调用根据成功请求从您的计划中扣除。每个计划都包含您每月可以进行的特定数量的调用。只有成功的调用(由状态 200 响应指示)才会计入您的总数。这确保失败或不完整的请求不会影响您的月度配额。
Zyla API Hub 采用月度订阅系统。您的计费周期将从您购买付费计划的那一天开始,并在下个月的同一日期续订。因此,如果您想避免未来的费用,请提前取消订阅。
要升级您当前的订阅计划,只需转到 API 的定价页面并选择您要升级到的计划。升级将立即生效,让您立即享受新计划的功能。请注意,您之前计划中的任何剩余调用都不会转移到新计划,因此在升级时请注意这一点。您将被收取新计划的全部金额。
要检查您本月剩余多少 API 调用,请参考响应标头中的 "X-Zyla-API-Calls-Monthly-Remaining" 字段。例如,如果您的计划允许每月 1,000 个请求,而您已使用 100 个,则响应标头中的此字段将显示 900 个剩余调用。
要查看您的计划允许的最大 API 请求数,请检查 "X-Zyla-RateLimit-Limit" 响应标头。例如,如果您的计划包括每月 1,000 个请求,此标头将显示 1,000。
"X-Zyla-RateLimit-Reset" 标头显示您的速率限制重置之前的秒数。这告诉您何时您的请求计数将重新开始。例如,如果它显示 3,600,则意味着还有 3,600 秒直到限制重置。
是的,您可以随时通过访问您的账户并在账单页面上选择取消选项来取消您的计划。请注意,升级、降级和取消会立即生效。此外,取消后,您将不再有权访问该服务,即使您的配额中还有剩余调用。
为了让您有机会在没有任何承诺的情况下体验我们的 API,我们提供 7 天免费试用,允许您免费进行最多 50 次 API 调用。此试用只能使用一次,因此我们建议将其应用于您最感兴趣的 API。虽然我们的大多数 API 都提供免费试用,但有些可能不提供。试用在 7 天后或您进行了 50 次请求后结束,以先发生者为准。如果您在试用期间达到 50 次请求限制,您需要"开始您的付费计划"以继续发出请求。您可以在个人资料中的订阅 -> 选择您订阅的 API -> 定价标签下找到"开始您的付费计划"按钮。或者,如果您在第 7 天之前不取消订阅,您的免费试用将结束,您的计划将自动计费,授予您访问计划中指定的所有 API 调用的权限。请记住这一点以避免不必要的费用。
7 天后,您将被收取试用期间订阅的计划的全额费用。因此,在试用期结束前取消很重要。因忘记及时取消而提出的退款请求不被接受。
当您订阅 API 免费试用时,您可以进行最多 50 次 API 调用。如果您希望超出此限制进行额外的 API 调用,API 将提示您执行"开始您的付费计划"。您可以在个人资料中的订阅 -> 选择您订阅的 API -> 定价标签下找到"开始您的付费计划"按钮。
付款订单在每月 20 日至 30 日之间处理。如果您在 20 日之前提交请求,您的付款将在此时间范围内处理。
您可以通过我们的聊天渠道联系我们以获得即时帮助。我们始终在线,时间为上午 8 点至下午 5 点(EST)。如果您在该时间之后联系我们,我们将尽快回复您。此外,您可以通过 [email protected]
