本科毕业设计(论文)题目：数控弯曲机的结构设计院 （系）： 机电工程学院 专 业： 机械设计制造与其自动化 班 级： 学 生： 学 号： 指导老师： 2024 年 6 月数控弯曲机的结构设计摘 要钢筋弯曲机是建筑施工场地必不可少的机械，能有效的提高生产效率，减少工人劳动强度，提高钢筋弯曲精度。本文所设计的钢筋弯曲机适用于弯曲Φ4-Φ12 毫米的钢筋。相比于市场上常用的其他钢筋弯曲机，本机可弯曲建筑用钢中的长钢筋，解决了目前大多数弯曲机不能装夹、送料、弯曲连续作业的问题。本机先通过矫直机构对盘状钢筋进行矫直，再通过弯曲装置对钢筋进行弯曲，满足弯曲要求之后，切断装置进行切断，最后卸料装置进行卸料。钢筋的弯曲角度由 PLC 通过控制步进电机来实现，能实现弯曲角度的自动化本文对 V 带轮、轴和一些关键零部件进行了设计计算，并对轴、键和带等关键部件进行了力学分析计算和强度校核，表明该钢筋弯曲机完全符合设计要求。关键词：钢筋弯曲机；钢筋矫直机构；钢筋卸料机构；自动化A Structure Design of Numerical Control Bending MachineAbstractRebar bending machine is essential for construction machinery, can effectively improve the production efficiency, reduce the workers labor intensity and improve the bending precision.Thisarticle rebar bending machine is suitable for the design of bending Φ4-Φ12 mm reinforcement pared with the practical application of all kinds of steel bar bending machine, this machine has one big characteristic wicth is able to bend steel of long bar,and solve the problem that most bending machine can't make clamping, feeding and bending a continuous operation.First through straightening device for wire rod steel bar straightening and then bending device for steel bar bending ,and steel cutting device cut it to meet a certain length,at last,steel unloading device unload steel bar bent. The angle is realized by PLC wicth controlling the step motor , automatically.In this paper, the V belt wheel, shaft and some key parts are designed an...
