七十年代以来,我国冷挤压技术有了很大的发展,目前在机械工业中已对低碳钢、中碳钢、低碳合金结构钢、轴承钢、纯铁等零件进行冷挤压,有色金属材料更普遍应用冷挤压,对少数不锈钢、高温合金也能进行挤压生产。据不完全统计,全国约有300~400种零件用该法生产,挤压件重量从几克到15公斤,年产量约2~3万吨。在冷挤压设备方面,我国仿梅氏挤压机有160吨、300吨、400吨;卧式肘杆式挤压机有200吨、315吨、500吨,还有630吨液压挤压机;2500吨液压挤压机业已投产。
Since the seventies, China’s cold extrusion technology has made great progress, at present in the machinery industry has low-carbon steel, carbon steel, low carbon alloy structural steel, bearing steel, pure iron and other parts for cold extrusion, Non-ferrous materials more commonly used cold extrusion, a small number of stainless steel, high temperature alloys can also be squeezed production. According to incomplete statistics, about 300 to 400 kinds of parts are produced by the method in the whole country. The weight of the extrusion is from several grams to 15 kilograms, and the annual output is about 2 to 30,000 tons. In the cold extrusion equipment, China’s Meixi extruder 160 tons, 300 tons, 400 tons; horizontal toggle extruder 200 tons, 315 tons, 500 tons, there are 630 tons of hydraulic extruder ; 2500 tons of hydraulic extrusion machine has been put into operation.
