在我国重型锻压机械的发展中,蒸-空自由锻锤是最早发展的产品。2吨和3吨蒸-空自由锻锤早在1950年就曾仿制成劝,随后不久“拱式结构和桥式结构”的自由锻锤自行设计制造完成并投入批量生产。这里简介的单臂蒸-空自由锻锤是沈阳重机厂在无产阶级文化大革命中,在毛主席革命路线指引下,深入使用现场,总结使用经验,为克服“拱式结构”锻锤一些缺点而于1671年自行设计制造的2吨和3吨单臂蒸—空自由锻锤。这两种规格新产品的特点是:锤机架采用C型单臂式结构,它较“拱式结构”有更
In the development of heavy forging machinery in China, the steam-air free forging hammer is the earliest development of products. 2 tons and 3 tons of steam - air free forging hammer had been imitated as early as 1950, followed by the “arch and bridge” free forging hammer design and manufacture completed and put into mass production. The single-leg steam-air free forging hammer introduced here is a heavy machine factory in Shenyang in the proletarian cultural revolution, under the guidance of Chairman Mao’s revolutionary line, the in-depth use of the site, sum up the use of experience, to overcome the “arch structure” forging hammer some shortcomings And in 1671 to design and manufacture of 2 tons and 3 tons of one-leg steam-air free forging hammer. These two specifications of the new product features are: Hammer rack with C-arm structure, it is more than “arch structure” have more
