安装式仪表包括数字显示和指针显示两种型式,指针式仪表,内有一个指针机构,用来作为直接显示之用。所以,指针加工质量的好坏,对仪表质量和精确程度有着重要的影响。指针的结构型式,一般有两种:一种是用δ0.15—L4(y)铝箔直接通过落料→冲鼓→弯曲等工序加工而成;另一种是用ф0.4—LF2实心铝针管与弯曲成型的平衡锤杆零件,通过包接→冲扁→截尖等工序加工而成。我们厂曾对产量大、使用范围广、
Installation of the instrument includes two types of digital display and pointer display, pointer instrument, there is a pointer mechanism, used as a direct display purposes. Therefore, the quality of the pointer processing quality is good or bad, on the instrument quality and accuracy have an important impact. The structure of the pointer type, there are two general: one is δ0.15-L4 (y) aluminum foil directly through the blanking → drum → bending processes such as processing; the other is ф0.4-LF2 solid aluminum Barrel and bending the formation of the balance bar parts, through the package then → flat → flat-cut truncated cone and other processes. Our factory had a large output, the use of a wide range,
