解放前,我国的鍛压生产处于极为落后的状态。解放后,在党和毛主席的英明領导下,和全国其他部门一样,鍛压生产才得到了迅速的发展。同时,苏联帮助我国建設了156項企业,更加全面地推动了我国鍛压生产的发展。在这些企业里,有着現代化的采用最新技术設备的鍛压車間。但目前在为数众多的中批生产的工厂里,大多数还采用着比较落后的鍛压加工方法——自由鍛。这样的工艺方法和装备,根据目的鍛压生产发展的水平来看,已經是落后了。目前,鍛压生产的发展趋势是不断扩大模鍛的使用范围,促使所得到的制件与成品零件的尺寸和形状接近或完全一致,以便最大限度地节約金屬材料,并以实現机械化与自动化来代替繁重的手动操作。实現这样比较完善的生产面貌,起而代之的,显然是一些比較先进的鍛压机械。目前,除了在制造和供应上存在着問題以
Before liberation, China’s forging production was extremely backward. After the liberation, under the wise leadership of the Party and Chairman Mao, like other parts of the country, forging production has developed rapidly. At the same time, the Soviet Union helped China build 156 enterprises and promoted the development of forging production in China more comprehensively. In these companies, there are modern forging workshops using the latest technology equipment. However, at present, most of the factories that are mass-produced are still using a relatively backward forging process—free forging. Such process methods and equipment are already lagging according to the level of purpose of forging and production development. At present, the development trend of forging and press production is to continuously expand the use of die forging, to promote the resulting parts and finished parts to the size and shape of close to or completely consistent, in order to maximize the savings of metal materials, and to achieve mechanization and Automation replaces heavy manual operations. To achieve such a relatively complete production appearance, replaced by, obviously, some of the more advanced forging machinery. Currently, there are problems with manufacturing and supply
