電力機柜是機箱機柜的一種，主要用于電力行業和與此相關的，所以被稱之為電力機柜。電力機柜的生產加工完全按照鈑金加工的工藝流程操作。
Power cabinet is a type of chassis cabinet, mainly used in the power industry and related industries, so it is called power cabinet. The production and processing of power cabinets strictly follow the process of sheet metal processing.
在鈑金加工中，一般通過折彎來使板材具有合理的角度，已達到造型的需求。在鈑金加工折彎過程中，常常遇到許多問題，了解這些常見的問題及其處理辦法，可以幫助我們達到更好的工作效果。
In sheet metal processing, bending is generally used to make the sheet metal have a reasonable angle, which has met the requirements of the shape. In the bending process of sheet metal processing, many problems are often encountered. Understanding these common problems and their solutions can help us achieve better work results.
1.鈑金折彎后工件在折彎處變形，產生的原因是出現變形的原因是折彎速度快，而手沒有跟上工件折彎的速度導致的。解決辦法可以采用降低鈑金折彎速度，手扶工件與工件一同進行。
1. After the sheet metal is bent, the workpiece deforms at the bending point. The reason for the deformation is that the bending speed is fast, and the hand does not keep up with the bending speed of the workpiece. The solution can be to reduce the bending speed of the sheet metal and hold the workpiece together.
2.折彎較長的工件時會出現角度一頭大一頭小的情況。出現這種情況的原因一般有以下幾種：鈑金材料厚度不一致,一端厚一端薄；鈑金模具磨損不均,兩端高度不同；中間塊不平衡,不在同一水平上。解決的辦法可采用反饋給激光或NCT,讓其留意選料；換刀模；調整中間塊。
When bending longer workpieces, there may be situations where the angle is larger at one end and smaller at the other. There are generally several reasons for this situation: inconsistent thickness of sheet metal materials, with one end thick and one end thin; Uneven wear of sheet metal molds with different heights at both ends; The intermediate block is unbalanced and not at the same level. The solution can be to provide feedback to the laser or NCT to pay attention to material selection; Tool changing mold; Adjust the intermediate block.
3.在折彎Z字型時，某些工件會變形。出現這種情況首要是因為C處為后定規定位，折彎B處時，工件折曲上升運動，撞在后定規上，被后定規擠住。折彎成型后，D處就被擠變形。解決這個問題的方法就是采用后定規后拉功用。
When bending the Z-shaped shape, some workpieces may deform. The main reason for this situation is that position C is positioned by the rear fixing gauge. When bending position B, the workpiece bends and rises, hitting the rear fixing gauge and being squeezed by the rear fixing gauge. After bending and forming, D is extruded and deformed. The method to solve this problem is to use the back gauge and back pull function.
選擇合適的折彎方法和技術參數能夠又快又好的完成折彎任務，并能保證工件角度和尺寸的精度，為后續的組合加工提供方便。
Choosing appropriate bending methods and technical parameters can quickly and effectively complete bending tasks, and ensure the accuracy of workpiece angles and dimensions, providing convenience for subsequent combination processing.
