在钛部件组装时需要使用大量同种的螺栓和螺母。而钛最大的缺点是材料成本高,与钢材相比高出20倍以上,为此,提高材料利用率显得尤为重要。日本阪村机械研究所开发了纯钛紧固件低成本锻造成形生产技术,其特点如下。(1)线性送料装置为了使高价的钛材得到100%的利用,采用了可使φ1 A large number of bolts and nuts of the same type need to be used when assembling titanium parts. The biggest disadvantage of titanium is the high cost of materials, compared with steel more than 20 times higher, therefore, to improve material utilization is particularly important. Sakamura Machinery Research Institute of Japan developed a titanium fasteners low-cost forging forming technology, which are as follows. (1) Linear Feeding Unit In order to make the high-priced titanium material obtain 100% utilization, it is possible to make φ1
