一、上海锻造行业的发展上海锻造行业是在五十年代中发展起来的。随着机械工业的发展,锻造行业经过多次调整、改组和改造,得到迅速发展。目前已初步形成比较完整的锻造生产体系,具备了一定的生产能力。据1980年统计,本市锻造生产厂点占全市机电工业企业总数的10.9%,其中市局系统占56%,郊县系统占44%.职工共有18000余人,占全市机电职工总数的1.4%。锻造设备拥有量占全市金切机床的15%,年产锻件能力约40万吨。本市也初步建立了大锻件生产厂点,锻件质量有所提高,如船用锻件已获国际船级社的认可。手工工具和手术器械是本市锻件制品的主要出口产品。近年来上海锻造生产中也采用了一些新工艺、新技术,如:年产量达25万件的精密模锻圆锥齿轮;汽
I. The development of the Shanghai forging industry The Shanghai forging industry was developed in the 1950s. With the development of the machinery industry, the forging industry has undergone many adjustments, reorganizations and transformations, and it has developed rapidly. At present, a relatively complete forging production system has been initially formed and has a certain production capacity. According to statistics from 1980, the city’s forging production plants accounted for 10.9% of the total number of mechanical and electrical industrial enterprises in the city, of which the municipal bureau system accounted for 56% and the suburban county system accounted for 44%. There were more than 18,000 employees, accounting for 1.4% of the total number of mechanical and electrical workers in the city. Forging equipment accounts for 15% of the city’s gold-cutting machine tools, and its annual capacity for forgings is about 400,000 tons. This city has also initially established a large forging production plant. The quality of forgings has been improved. For example, marine forgings have been approved by the International Classification Society. Hand tools and surgical instruments are the main export products of the city’s forging products. In recent years, some new processes and technologies have also been adopted in Shanghai forging production, such as precision die forging bevel gears with an annual output of 250,000 pieces;
