问题的提出图1零件是注塑机上的合模油缸,由于加工不妥,造成在φ230~(+0.02)mm内孔左端有两处出现多处凹痕见图1A、B段),其深度单边分别为0.81和1.23mm,因此无法用一般电镀方法修复。但该油缸价值在万元以上,如报废经济损失大,而且严重影响了生产进度。为此,我们决定采用快速电镀法进行修复。因被镀部位面积大,镀层厚(直径方向要镀1.62～2.46mm),涂镀时间长,容易在被镀部位与不镀部位出现交接线。这些都给快速电镀带来了困难。
The problem is presented in Figure 1 parts injection mold clamping cylinder, due to improper processing, resulting in φ230 ~ (+0.02) mm hole at the left there are two multiple dents appear in Figure 1A, B), the depth Unilateral 0.81 and 1.23mm, respectively, and therefore can not be repaired with the general plating method. However, the fuel tank worth more than 10,000 yuan, such as scrap economic loss, but also seriously affected the progress of production. To this end, we decided to use the rapid plating method for repair. Due to the plating area, coating thick (diameter direction to be plated 1.62 ~ 2.46mm), coating a long time, easy to be plated parts and unplated parts appear intersection line. These have brought difficulties for rapid plating.
