Manufacturing 深拉组件 with consistent quality and fast turnaround starts with expertise in deep draw tooling design. ATACO is the industry leader in 深拉冲压 and die design. ATACO toolmakers have decades of metal forming experience and optimize deep draw tooling design based on engineering data, material properties, press speed and many other factors.

Deep draw tooling includes all the hard tooling components used to shape flat sheet metal into a 深拉零件:
模具和冲头由工具钢制成，而压边圈和顶出筒通常由合金钢制成。冲头和拉伸环的边缘是圆形的，因此金属板坯在模具的边缘上平滑成型。
液压和机械深拉压力机 are used to produce deep drawn stampings. Deep draw presses have customizable configurations to accommodate different tooling requirements, and can have single or multiple stations.
ATACO can provide deep drawing along with secondary operations such as trimming, piercing, and forming. If volume is too low to justify tooling for these additional operations, we can trim and pierce via 5轴激光切割.
冲头位于冲压床上，模具直接位于其上方。压边器（带有冲头开口的板）将毛坯的边缘固定在模具上，以帮助控制材料流入模具的腔体。这有助于最大限度地减少成品零件中的缺陷。
当上模将坯料向下压时，金属材料会在冲头上成型。在拉拔过程中，缓冲压力垫使毛坯与冲头末端保持接触，以减少可能导致撕裂的拉应力。
工件成型后，顶出缸用刚好足够的力将零件顶出以将其释放从模腔中取出，而不会造成损坏。
设计深拉模具需要金属成型专业知识。有许多不同的因素需要考虑，这些因素会影响零件质量、交货时间和最终成本。
Depth of draw and draw ratio determine the shape of the punch and die cavity, as well as the diameter of the metal blank.
Part complexity determines the number of stations needed. The toolmaker also has to incorporate elements that move the workpiece from one station to the next.
Production volume and drawing force determine which material is used for the punch and die.
Workpiece material knowledge is crucial for successful tooling design. Material type, grade, heat treating, and anisotropy (directional properties) affect flow and therefore tooling requirements. Softer materials are easier to draw and require less force. Some metals have more springback than others. The desired thickness of the blank and finished part also affect tool design.
ATACO 工具制造商在设计深拉零件的工具时会考虑这些和许多其他因素。
ATACO uses state-of-the-art production simulation software for 深拉模具设计. FASTFORM® Advanced allows our engineers to quickly assess deep drawn part feasibility, blank shape and springback, as well as identify potential forming issues. Simulation data on formability risks and optimal material usage is then sent to our tooling department.
ATACO toolmakers use the software in the 深拉模具设计 phase to evaluate component and tool geometry, incorporate material properties, and account for predicted production effects resulting from friction, blank holder force, pad pressure and more.
设计过程包括许多影响最终成本的因素。使用专门的软件来优化模具设计和成本效益可以提高我们的大批量制造客户的投资回报率。
