国产HB—3000型布氏硬度计在我国使用比较广泛。是测定一般钢材或锻件硬度的一种有效的仪器。但在使用中,我们发现原设备本身的一些缺点,如备件短缺,故障频繁,维修困难,加载、卸荷信号不明显等,给生产带来一定的影响。我们车间经过两个多月的努力,用了很少的经费,将一台老式硬度计进行了改装,在硬度计的操作过程中实现了集成电路程序控制。即从电机启动到加载,试验力保持时间,卸荷
Domestic HB-3000 Brinell hardness tester is widely used in our country. Is to determine the hardness of a typical steel or forging an effective instrument. However, in use, we found that the original equipment itself some shortcomings, such as spare parts shortage, frequent failures, maintenance difficulties, loading, unloading signal is not obvious, to produce a certain impact. After more than two months of hard work in our workshop, with a small amount of funding, an old-fashioned hardness tester was retrofitted and the integrated-circuit process control was implemented during the operation of the durometer. That is, starting from the motor to load, test force to maintain time, unloading
