钣金加工成型加工工艺的设计方案涉及到许多要素，如磨具规格、毛胚样子、钢板薄厚、包边条力、拉延筋抗力、磨擦、润化这些。 钣金属板材材质材料生产加工叫钣金加工。实际例如运用板才制做烟筒、不锈钢桶、汽车油箱机油桶、通风风管、弯管大小头、天园地区、型管形等，关键工艺流程是裁切、钣金折弯扣边、弯折成形、电焊焊接、铆合等，必须必须几何图形专业知识。

1.进行方法要合，要便捷节约原材料及工艺性能

2.有效挑选空隙及包边条方法，T=2.2下列问隙0.3，T=2-3问隙0.6，包边条方法选用长边包短边(门边框类)

3.有效考虑到尺寸公差尺寸：负差一直走，正差走一大半;孔形规格：正差一直走，负差走一大半。

5.毛边方位

5抽牙、压铆、撕破、冲突点(包)，等部位方位，画出剖视图

6.核查材料，板厚，以板厚尺寸公差

7独特视角，折弯角内半经(通常R=0.6)要试折而定进行

8.有易错误(类似不一样)的地区应重中之重提醒

10规格较多的地区得加变大图

11. 需喷漆维护地区须表达

The design scheme of sheet metal forming process involves many factors, such as the specification of the abrasive tool, the shape of the blank, the thin thickness of the steel plate, the edge-binding force, the resistance of the draw bead, the friction and the lubrication. Sheet metal material material production processing is called sheet metal processing. In practice, for example, plates are used to make smoke pipes, stainless steel drums, oil drums for automobile oil tanks, ventilation pipes, elbow heads, pipe shapes, etc. The key processes are cutting, bending, forming, welding, riveting and so on, which must have the professional knowledge of geometry. 1. The method should be combined to save raw materials and process properties. 2. T 2.2 the following clearance 0.3, t 2-3 clearance 0.6, the method of using long side-pack and short side-door frame 3. Effective consideration of dimensional tolerance dimensions: negative difference always go, positive difference go more than half; Hole Size: positive difference always go, negative difference go more than half. 5. BURR bearing 5 extraction, pressure riveting, tearing, conflict point package, and other parts of the direction, draw a profile 6. Check material, plate thickness, with plate thickness dimension Tolerance 7 unique angle of view, bending angle inside half through usually r 0.6 to be tested and fixed 8. Error-prone areas with similar differences should be top of the list. 10 areas with more specifications should be enlarged. 11. Painting areas to be maintained shall be described
