五金冲压的工作流程

什么是金属冲压?

Metal stamping technology is a processing method that uses metal stamper to apply mechanical pressure to flat metal床单。是一种高效、高精度的成形工艺。 利用预先设计的模具形状,结合压力机向下的挤压力,使金属板材在室温下发生塑性变形或脱离,从而快速制造出所需的三维零件。整个过程涉及精密的金属成型、弯曲、切割等工艺,适合制造从简单到复杂的部件。

In terms of metal stamping, the stamp metal process first involves fixing the metal sheet in place.操作人员将一块平坦的金属板放置在模具的下模上,上模(即金属压模)在压力机的驱动下垂直向下运动。上下模具闭合后,模具的切削刃或成形结构对金属施加压力,使其拉伸、弯曲或断裂。该工艺的优点是能够一次完成多道工序,显着提高生产效率,特别适合精密零件的批量生产。

五金冲压的基本工艺有哪些?

金属冲压技术是通过金属冲压件将金属板材冲压成特定形状的一系列技术。以下四个工艺体现了其在复杂零件制造中的精细化应用:

1.渐进式冲压

通过多组相连的金属桩,在一条流水线上逐步完成冲孔、弯曲、成型等多道工序。JS company adopts the advanced mould technology developed by itself to achieve efficient mass production through the mould of different workstations continuously.

For example, a car radiator grilles can be made by stamping step by step, bending and rotating at the same time.The precision of die connecting rod can be ±0.005mm to ensure part consistency and increase production speed by 40%.

2.传递模具冲压

Suitable for large or intricately shaped parts, metal billets transported between workstations by robotic arms or conveyor belts.JS伺服压力机与自动化系统无缝配合,精确控制钢坯定位。For example, in aerospace component manufacturing, a combination of transfer molding and heat treatment ensures that titanium alloy parts remain structurally stable after multiple deformations and reduce scrap rates by 60%.

3.滑动模具冲压

Specially designed for multi angle bending, complex curve forming is achieved through horizontally sliding metal stamps.JS's flexible mold system supports online adjustment of bending angles.例如,在电子元件支架的生产中,一次冲压即可完成三个不同方向的弯曲,材料利用率提高15%。特别适合小批量定制订单。

4.深度绘图

By stretching the metal stamp, metal sheets is made into a deep cavity parts.凭借先进的模具组合和液压模具组合补偿,JS的深度拉伸技术可以成功成型直径1.5m、表面光洁度≤0.8μm的大型容器,满足医疗器械对表面无瑕疵的严格要求。

金属冲压工艺的关键步骤是什么?

1.材料预处理及模具匹配

根据零件要求选择金属板材(如铝、钢、铜合金等),并通过整平、清洗等预处理使表面光滑。JS公司利用激光测量技术校准金属板材的厚度公差(±0.05mm),用于高精度金属的成形参数冲压模具。

2.模具设计与调试

基于零件3D模型,设计五金冲压模具的几何形状和冲压路径,并通过CAE模拟优化模具的应力分布。例如深拉模具需要渐变R角设计以防止开裂,JS的独立模具加工中心可以完成微米级边缘抛光以保证表面粗糙度Ra≤0.4μm。

3.冲压成型阶段

将金属板放置在冲压台上,通过金属冲压模具和液压/伺服压力机的配合完成塑性变形。例如拉伸过程中模具的渐进间隙设计可以控制材料流动并防止起皱或开裂,JS的实时压力反馈系统可动态调整边缘压力,使成品率提高至99.2%。

4.后处理和表面优化

金属冲压产品经过修整、镶边或电解抛光,以去除毛刺并提高光洁度。JS的自动化去毛刺设备可以处理尺寸达0.1mm的微小零件,结合PVD涂层技术,提高零件的耐腐蚀性,满足汽车电池外壳等高耐用性要求。

5.质量检验和数据闭合

使用CMM或光学扫描验证金属冲压件的尺寸精度(例如孔距≤0.01mm),并通过MES系统跟踪模具参数和生产数据。JS的AI视觉检测系统可以实时识别0.02mm级别的缺陷,保证批量一致性。

五金冲压模具有哪些类型?

金属冲压模具是制造业的核心工具。主要分为以下几类:

1.按流程类型分类

打孔模具:用于分离金属板材,完成切割、冲孔、切割等工序,以获得所需的轮廓或孔。模具的核心是凹模和凹模的组合。模具间隙的精度决定了模具断面的质量。广泛应用于硬件和电子元件的生产。

弯曲模具:将金属板以特定角度或形状(如U型、V型)弯曲,通过加压凸凹模组合完成弯曲,并考虑回弹补偿。

深化模具:通过凸压凹模将扁坯拉伸成空心三维零件(如杯子或圆柱体)需要控制起皱和裂纹。适合生产炮弹、坦克等

成型模具:用于金属板材的局部塑性变形,如胀形、撕裂、颈缩等,将材料拉伸或压缩成特定形状,适合加工复杂曲面或钢筋钢结构。

复合模具:在一次冲压中完成冲压、切削、成型等多个步骤,并通过凸模结构的组合实现高效加工。适合高精度、多工序批量生产中小型零件。

输入模具(连续模具):通过多次连续对带材进行冲压、冲压、弯曲、成型等,最终对成品进行高效切割,适合小型精密零件的大规模生产。

2.按模具结构分类

  • 单轨模具:只需一次冲压(如冲压或切削),结构简单,成本低,适合小批量生产或简单零件加工。
  • 组合模具:

复合模具:多个流程(例如切割和拉伸)在同一工作站进行。

Progressivemold: Continuous processing (冲压→弯曲→切割)在不同的工作位置。

  • Transfer mold:used for the transfer of blank of multiple presses and robotic arm, suitable for large parts such as automobile overlay.

摘要

In the metal stamping industry, the performance of metal stamp is closely related to the accuracy and quality of the final product, and to achieve this goal, it must rely on high-precision pre-processing technology.

Through steps such as surface cleaning, deburring, annealing, andsurface modification(such as phosphating and lubricating coatings), not only can the ductility of metal materials be significantly improved and the risk of cracking or oxidation during stamping be reduced, but it can also lay a solid foundation for subsequent metal stamping operations.

JS combines high-precision CNC machining technology with environmentally friendly processes, incorporating the concept of sustainable development into the pre-processing stage, ensuring that metal stamping parts can maintain consistency whether they are structurally complex or mass-produced.

This full process optimization from material preparation to finished product delivery not only improves production efficiency (reducing project cycle by 15%), but also promotes the industry's transformation towards high efficiency, low consumption, and high added value through technological innovation.
