金属冲压中的公差是什么?按工艺和材料的典型公差
金属冲压中的公差是什么?按工艺和材料的典型公差

金属冲压中的公差是指为冲压件规定允许尺寸偏差的系统,通常以毫米或英寸的加/减数值表示。实际而言,这是工程师与制造商之间的约定,定义了某个特征在功能正常的前提下可以偏离标称设计的程度。典型公差范围从精密精冲的±0.05毫米到标准级进模冲压的±0.50毫米不等,材料类型、厚度和特征几何形状都会影响这些基准数值。金属冲压中标...

定制金属冲压件的最低起订量是多少?
定制金属冲压件的最低起订量是多少?

定制金属冲压件的起订量(MOQ)通常为:级进模冲压500至5,000件,而原型和小批量冲压可低至50至100件。具体起订量取决于零件复杂度、材料厚度、模具成本以及所采用的冲压工艺(级进模、多工位传递模或四滑道模)。对于大多数标准精密零件,BQUQ为量产提供1,000件的实用起订量,同时支持更低数量的初始打样和验证。零件...

冲压模具多少钱?完整模具价格解析
冲压模具多少钱?完整模具价格解析

一套典型的冲压模具价格在3,000至150,000美元之间,中等复杂程度的汽车支架量产模具通常为25,000至60,000美元。最终价格取决于零件尺寸、材料厚度、所需吨位和工站数量,其中级进模的价格比简单单冲模高出3至5倍。要获得精确报价,您必须提供3D模型和年产量,因为这些因素会使成本产生数量级的变化。不同类型的冲压...

冲压模具能用多久?模具寿命与维护指南
冲压模具能用多久?模具寿命与维护指南

冲压模具的使用寿命通常在50万至500万次冲程之间(硬质合金模具),而高速钢(HSS)模具在需要大修前平均可达到10万至100万次冲程。具体寿命取决于四个主要变量:工件材料(厚度和硬度)、模具材料等级、冲压速度以及预防性维护计划的有效性。在本指南中,我们根据BQUQ东莞工厂20年的生产数据,提供具体的冲程次数、单件成本...

金属冲压中的毛刺是什么?如何控制?
金属冲压中的毛刺是什么?如何控制?

金属冲压中的毛刺是指工件在切割或剪切过程后残留的不希望的凸起边缘或小块材料。当冲头和模具之间的间隙不正确、模具磨损或材料延展性超过断裂点,在切割边缘留下变形唇边时,就会形成毛刺。您可以通过优化模具间隙(通常为每侧材料厚度的5-10%)、保持模具锋利以及在对公差有要求时应用二次去毛刺工艺(如振动光饰或电化学去毛刺)来控制...
