钢筋切断机主要用于剪切建筑钢筋及圆钢下料。我国于60年代初,开始生产GQ40型钢筋切断机。该机型结构简单,无离合器机构、无送料装置、能耗和材耗都高、效率低(测试与计算值见表1)。其性能指标,对照国家标准GB8521-87钢筋切断机,差距较大,属于淘汰产品。为加速更新换代,我厂与中国建筑科学研究院建筑机械化研究所,参照国外同类样机共同研制出GQ40型钢筋切断机及GQ40L型立式钢筋切断机。我厂参加这两种机型的研制,分
Rebar cutters are mainly used to cut construction steel bars and round steel blanks. In the early 60s, China started to produce GQ40 steel cutters. The model has simple structure, no clutch mechanism, no feeding device, high energy consumption and material consumption, and low efficiency (see Table 1 for test and calculation values). Its performance index, compared with the national standard GB8521-87 steel cutting machine, has a big gap and is a phase-out product. In order to speed up the replacement, our factory and the Institute of Construction Mechanization of the Chinese Academy of Building Research jointly developed a GQ40 steel bar cutting machine and a GQ40L vertical steel bar cutting machine with reference to similar foreign prototypes. I plant to participate in the development of these two models, points
