1、可调式钢筋弯曲机的设计摘 要：本文在充分了解现在国内外钢筋弯曲机的基础上，分析各种弯曲机的优缺点，利用已有的样品及技术，通过鉴定改进，设计确定出了一种单人操作的可调式钢筋弯曲机。首先通过对现有两种钢筋弯曲机传动方案的分析与比较，再结合具体实例，确定了全齿轮转动方案，然后对所设计钢筋弯曲机的工作原理进行了描述，并对钢筋弯曲机的结构进行了详细的分析解释，在整个的设计中，对于结构的分析是非常重要的，它是本次设计的关键内容。其次在对结构分析清楚之后通过对 GW-40 钢筋弯曲机机构位置和动力参数的简单计算，参照现有工作台面的尺寸，制定了所设计钢筋弯曲机工作表面的各部件参数，由此计算出弯曲钢筋所需的扭矩
2、从而确定了适合本弯曲机的电动机.其次根据电动机的参数分配好传动比并进行大量的计算确定了 V 带、各个齿轮以及轴的主要参数，来完成整体设计。对于可调式钢筋弯曲机的设计而言，角度的可调性也是设计的一个重要方面，它主要是靠控制设备来实现，故在本篇的最后两章对控制设备的选择和电机的选择作了简要的说明，由此完成了 GW-40 型可调式钢筋弯曲机的设计。关键词：钢筋弯曲机，全齿轮传动，结构分析，可调性太原工业学院毕业设计The design of the adjustable steel bending machineAbstract：On the basis of fully understanding
