我厂开关板电表有一根直纹t=0.5mm的轴(见图1所示)。技术要求:①直纹不允许有明显扭曲、乱扣;②搓花后的椭圆度在公差范围内;③不允许两端大、中间小。材料为LY12-Y,由φ1.6mm铝线搓成。原加工方法除下料外全部为手工作业,这种工艺劳动强度大,效率低,一个班只能生产300件左右,且质量不稳定,直纹花常发生扭曲、烂齿现象。为此我们设计制造了一台专机,经过几年的实践证明,完全能满足生产要求。
I plant switch board meter has a straight t = 0.5mm axis (see Figure 1). Technical requirements: ① straight lines are not allowed to have obvious distortion, chaos deduction; ② after rubbing the ovality within tolerance; ③ not allowed at both ends of the large, small in the middle. The material is LY12-Y, made of φ1.6mm aluminum wire. Except for the original processing method, all the manual work, the process of labor-intensive, low efficiency, a class can only produce about 300, and the quality is unstable, straight-wrought flowers often distorted, rotten teeth phenomenon. To this end, we designed and manufactured a special plane, after several years of practice has proved that fully meet the production requirements.
