鈑金加工成型加工工藝的設計方案涉及到許多要素,如磨具規(guī)格、毛胚樣子、鋼板薄厚、包邊條力、拉延筋抗力、磨擦、潤化這些。 鈑金屬板材材質材料生產加工叫鈑金加工。實際例如運用板才制做煙筒、不銹鋼桶、汽車油箱機油桶、通風風管、彎管大小頭、天園地區(qū)、型管形等,關鍵工藝流程是裁切、鈑金折彎扣邊、彎折成形、電焊焊接、鉚合等,必須必須幾何圖形專業(yè)知識。
1.進行方法要合,要便捷節(jié)約原材料及工藝性能
2.有效挑選空隙及包邊條方法,T=2.2下列問隙0.3,T=2-3問隙0.6,包邊條方法選用長邊包短邊(門邊框類)
3.有效考慮到尺寸公差尺寸:負差一直走,正差走一大半;孔形規(guī)格:正差一直走,負差走一大半。
5.毛邊方位
5抽牙、壓鉚、撕破、沖突點(包),等部位方位,畫出剖視圖
6.核查材料,板厚,以板厚尺寸公差
7獨特視角,折彎角內半經(通常R=0.6)要試折而定進行
8.有易錯誤(類似不一樣)的地區(qū)應重中之重提醒
10規(guī)格較多的地區(qū)得加變大圖
11. 需噴漆維護地區(qū)須表達
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
