在拉制裸铜丝、电阻丝等金属丝过程中常常面临测量其直径的误差问题,由于拉丝时金属丝的线速度很高,采用普通量具是无法进行测量的。虽然采用电子测量仪器能够满足生产要求,但是成本高,操作复杂,对于一般中小企业来说日前还不具备这样的条件。为此我们设计了与千分表配套的机械式测量装置。1.测量原理测量原理见图1。首先将高速移动的金属丝5嵌入导向轮4、8槽中,然后向上移动滑块7使测
In the process of drawing bare copper wire, resistance wire and other metal wire, it often faces the problem of measuring the error of its diameter. Since the wire speed of wire drawing is very high, ordinary measuring tools can not measure. Although the use of electronic measuring instruments to meet production requirements, but the high cost, complex operation, for the general SMEs have not yet have such a condition. To this end we have designed a mechanical measuring device that is equipped with a dial indicator. 1. Measuring principle Measuring principle shown in Figure 1. First of all the high-speed wire 5 embedded in the guide wheel 4, 8 slots, and then move the slider 7 up to the test
