不锈钢冲压:304、316及弹簧钢设计要点
不锈钢冲压:304、316及弹簧钢设计要点

不锈钢冲压与碳钢相比,需要不同的工程方法,因为其屈服强度更高、加工硬化率更高,且回弹特性不同。对于304、316和弹簧钢(如301和17-7PH),成功生产的关键在于控制材料回火状态、模具间隙和冲压速度,以管理尺寸漂移和边缘质量。本文基于BQUQ 20年的大批量生产数据,为这三类材料提供了具体的公差、模具参数和成本基准...

级进模冲压详解:工艺、公差与成本效益
级进模冲压详解:工艺、公差与成本效益

级进模冲压是一种高速金属成形工艺,其中连续的金属卷料被送入单个模具内的多个工位,每个工位执行不同的冲裁、弯曲或拉深操作,在一次冲压行程中生产出成品零件。该工艺的生产速度可达每分钟1200次冲程,公差精度高达±0.01 mm,是制造大批量精密零件最具成本效益的方法。该工艺将冲孔、落料、压印和成形集成在一个同步模具中,消除...

冲压润滑详解:如何选择合适的油品以延长模具寿命
冲压润滑详解:如何选择合适的油品以延长模具寿命

金属冲压润滑是指在工件与模具表面之间受控地施加工程流体或薄膜,以减少摩擦、控制热量,并在剪切、拉深和成形操作中防止咬合或卡死。润滑剂的正确选择取决于材料类型、冲压严重程度和模具材料,可选范围从用于轻载落料的高流动性石油基油品,到用于深拉延的重型氯化或合成拉延油。使用错误的润滑剂可使模具寿命缩短高达40%,并将零件报废率...

金属冲压与CNC加工:小零件成本与质量对比
金属冲压与CNC加工:小零件成本与质量对比

对于直径小于50mm的小型零件,当产量超过10,000件时,金属冲压通常比CNC加工便宜30-70%,而CNC加工在尺寸精度上更优,可达±0.005mm,冲压则为±0.05mm。最佳选择取决于您的年产量、公差要求和零件几何复杂度。本指南提供数据驱动的对比,帮助您为特定应用选择正确的制造工艺。成本结构分析:您的钱花在哪里...

如何设计金属冲压零件:精密制造的10条规则
如何设计金属冲压零件:精密制造的10条规则

为金属冲压设计零件,需要从根本上从减材加工逻辑转变为大批量级进模思维。简而言之,您必须设计均匀的壁厚、充足的弯曲半径和一致的材料流动,才能在每分钟300件的生产速度下实现±0.05毫米的公差。遵循10条具体的设计规则,与BQUQ东莞工厂优化不佳的设计相比,您可以降低高达30%的模具成本,并将单件价格降低15-20%。#...
