工具电极是电加工用的“刀具”。电极制造质量直接影响电加工型腔模的质量。现以上海牌2吨汽车上的右转向节(见图1)为例,就石墨电极的制造介绍如下:一、电极套样板的制造首先,根据热锻件图(如图1。假如设放收缩率就不要热锻件图),做电极外形的套样板一块。套样板材料可用1～1.5毫米厚的铁皮。轮廓大小按锻件外形尺寸,每边放大40～50毫米,成长方形。铁皮经调整平直、表面砂光后,作一角尺基准面,并涂上墨汁,以便划出各部分名义尺寸的轮廓线。然
The tool electrode is a “tool” for electrical processing. Electrode manufacturing quality directly affects the quality of cavity mold. Now Shanghai 2 ton motor vehicle on the right steering knuckle (see Figure 1), for example, the manufacture of graphite electrodes are described below: First, the manufacture of the electrode sleeve model First, according to the hot forgings diagram (Figure 1. If the set shrink Do not rate the hot forgings map), to do a set of electrode shape of a sample. Set of sample materials available 1 ~ 1.5 mm thick sheet metal. Outline size by forgings dimensions, each side enlarge 40 ~ 50 mm, grow square. After adjustment of the metal sheet, the surface is sanding, make a square reference surface, and coated with ink, in order to draw the outline of the nominal size of each part. Of course
