自动折弯机输送机构设计（机械cad图纸） 大学学位论文.doc

摘要：随着中国经济的快速发展，各行各业也跟随其后发展起来，基础设施建设如火 如荼地进行着。厂房、设备、交通设施需求急剧增加，各种金属管的需求已远远不 能满足，许多金属管的形状要求也不断复杂化，从而催生了弯管机系统设计和开发。 本文设计的是经济性能较好且精度较高的管材折弯机，主要针对的是直径20mm 以下的管材。 此弯管机主要是用夹紧机构把管材压紧在主轴上的成型轮模的槽中， 然后通过主轴的旋转来实现管材的折弯，这种折弯是二维的。优点是经济性好性好， 制造使用简单，而且适用范围广，缺点就是精度较低，这种物理折弯还会产生一定反弹。传统的手工折弯很难控制角度和距离，而且精度太低，往往很难满足需求，相反现代化的全自动数控折弯机各方面性能都比较好，但是非常昂贵，不适合中小企业，而我这个折弯机就能既保证一定的精度，也有很好的经济性，具有广泛的运用空间。 关键词：管材 折弯机 折弯 夹紧 液压 Abstract：With the rapid development of Chinese economy,every walk of china developed quickly.Many basic foundation is to be built.We need more workship,facility and transportation.The steel tube couldn抰 satisfy need of.For some curling tubes are required,弯many engineers begin to design the curling machine. The machine which I design is a kind of good presicion and proper price. It抯 used for curling the tube which抯 diameter is under 20mm. The curling process is very simple:firs the clamp equipment clamp the tube,then principal xis go round and round.The machine is easy for using and making.Also the cost is proper and it could be used in many circumstance.But the precision is not high,and this kind of curling shall have bring a bit rebound. Taditionnal byhand curling hardly could control the curling angel and space.It has poor presicion .With the development of the industry ,traditional curling method couldn抰 satisfy the presicion requirement .In the other hand,the CNC curling machine has a very good presicion ,but it抯 very expensive.As my design has a good presicion and a proper price.It抯 could be used in many factory. Keywords:steel tube curling machine curl clamp hydraulic pressure 目 录 中文摘要................................................1 英文摘要................................................1 引言 1.1折弯机的概述.......................................4 1.2折弯机的分类.......................................4 1.3国内外发展情况.....................................4 自动折弯机输送机构的组成部分及运动过程 2.1自动折弯机输送机构的结构...........................5 2.2自动折弯机输送机构的动作过程.......................5 2.3自动折
