1000吨摩擦压力机结构简单,近年来在模锻方面得到较大的推广。上海地区一九六九年开始投产以来,已发展到14台。经过几年使用,陆续进入修理阶段。现将我厂在修理中遇到的一些问题,提出供大家参考。一、螺母的装拆螺母(图1)材料一般用ZQSn 6-6-3、ZQAl 9-4。和机身配合大都采用过盈配合,装一圆柱销承受扭矩,但亦有用键者。我厂采用的过盈是0.20～0.26。零件大又有过盈,装拆都很困难,过去装配先用千斤顶顶入一部分,再开反车顶入。而拆卸时却用撞块撞 The structure of the 1000-ton friction press is simple. In recent years, it has been greatly popularized in die forging. Since the start of production in 1969 in Shanghai, Shanghai has grown to 14. After several years of use, one after another into the repair phase. Now I plant some problems encountered in the repair, put forward for your reference. First, the nut nut (Figure 1) The material is generally used ZQSn 6-6-3, ZQAl 9-4. And the fuselage with most of the interference fit, install a cylindrical pin to bear the torque, but also useful keys. Our factory adopted the interference is 0.20 ~ 0.26. Large parts have interference, assembly and disassembly is very difficult, in the past the first jack into the top part of the assembly, and then open the anti-car into the roof. The demolition but hit with a collision block
