本文对称为外板的汽车面板和称为内板的结构零件,从制订工艺到冲压完成的全过程中各种缺陷逐一地作简要叙述。外板以小轿车的后面板为例,内板以前门柱下段为例。 简单地说,缺陷受零件的形状及功能、工艺方案、模具设计、模具制作的优劣等多种因素的影响,所以条件不同缺陷也就不同。 后面板的加工 后面板的概略形状如图1所示。A点至B点的部分,除了要求装上汽车之后外观漂亮、尺寸精确之外,尤其不能有皱纹、伤
In this paper, the outer panel of the car panel and called the inner parts of the structural parts, from the development process to the completion of the stamping of the various defects one by one for a brief description. The outer panel to the car’s rear panel, for example, the inner plate to the lower section of the front door as an example. Simply put, the defects by the shape and function of the parts, process options, mold design, the advantages and disadvantages of mold making and other factors, so the conditions of different defects are different. Rear panel of the processing of the general shape of the panel shown in Figure 1. A point to point B part, in addition to require the appearance after loading the car beautiful, accurate size, in particular, can not have wrinkles, injuries
