近几年来,多工位板料冲压自动压力机(以下简称多工位压力机)有所发展,并正在向大吨位方向发展,但一般认为发展速度并不快。到目前为止,世界最大的是美国维尔森(Verson)公司生产的4600吨三滑块(600、2000、2000吨)四柱结构形式,工位数最多达16个,工位间距最大为1000毫米。西德舒勒(Schuler)公司从1900年开始生产小吨位简单的多工位压力机,1955年发展了三柱结构形式,1960年制成了3000吨三柱结构形式,具有八工位,行程为350毫米,工位间距为750毫米,生产率
In recent years, the multi-station sheet metal stamping automatic press (hereinafter referred to as the multi-station press) has been developed and is being developed toward a large tonnage. However, it is generally believed that the development speed is not fast. So far, the world’s largest is the 4,600-ton three-block (600,2000,2000 tons) four-post version produced by the U.S. company Verson with up to 16 stations and up to 1,000 mm of station spacing. Schuler started production of small-tonnage simple multi-station presses from 1900, developed a three-column structure in 1955 and a 3,000-ton three-column structure in 1960 with eight stations, 350 mm, station spacing 750 mm, productivity
