中国建筑科学研究院建筑机械化研究所分别与沈阳市建筑施工机械厂、合肥工业大学机电厂共同研制的GW_32型、GW_40型钢筋弯曲机(图1为GW_32型),于一九八六年十一月相继在沈阳和合肥通过了部级技术鉴定。这两种新型的钢筋弯曲机都是在参照国外样机的基础上并结合我国的具体国情研制成功的换代新产品。其中GW_32弯曲机填补了我国钢筋弯曲机系列产品的空白。这两种弯曲机能满足建筑施工现场及混凝土
Institute of Construction Mechanization, China Academy of Building Research, and GW_32 and GW_40 steel bending machines jointly developed by Shenyang Construction Machinery Plant and Hefei Industrial University Machine Power Plant (Fig. 1 GW_32), 1986 On a monthly basis, it passed the ministerial technical appraisal in Shenyang and Hefei. These two kinds of new steel bending machines are based on the reference of foreign prototypes and combined with our country’s specific national conditions to successfully develop new products. One GW_32 bending machine to fill the gap in China’s steel bending machine series. Both bending machines can meet the construction site and concrete
