钢筋弯曲机设计说明书 摘要 钢筋弯曲机是建筑业常用的工程机械之一，主要用于各种型号的钢筋的弯曲，以用于工程施工工地上。通过强度计算分析，认为现有弯曲机的大部分零件有较大的设计裕量，需要改变个别零部件及电动机功率即可大幅度提高加工能力，满足ф40钢筋的弯曲加工。.本文所设计的半自动可调速钢筋弯曲机适用于弯曲Φ6-Φ40毫米钢筋之用，本机的传动机构采用全封闭式，变速杆换挡，可使工作盘得到两种转速，钢筋的弯曲角度由工作盘侧面的挡块调节，机械部分通过电器控制实现半自动。钢筋弯曲机适用于建筑行业弯曲Φ6—Φ40钢筋之用。本机工作程序简单，弯曲形状一致，调整简单，操作方便，性能稳定，它能将Q235Φ40圆钢或Φ8—Φ32螺纹钢筋弯曲成工程中所需要的各种形状。 关键词钢筋弯曲机；弯矩；主轴扭矩 Abstract Steel be
