1、引言
弯管机是休闲用品及工艺装饰品生产行业中的重要设备，由于产品种类丰富，形状千变万化，相应弯管的形状、尺寸及大小半径各不相同，在以前生产中，主要有液压弯管机、手动弯管机、简易电动弯管机等，这对大批量生产以及产品尺寸的千变万化不相适宜。本文介绍的弯管机是根据实际生产需要，开发、研制而成，并已投入实际生产中，产生了显著的效益。
2、系统介绍
该弯管机的控制系统原理图如图1所示，主要由PLC、变频器、传感器、人机界面、主副电机等组成。该机的主体部位，由八组滚轮组成，如图2所示，一次可同时生产八根管子，提高了效率。主电机由变频器控制，通过HMI可调整滚轮的速度；管子弯曲半径由副电机通过涡轮副减速控制滑块下压和上升；弯管长度、半径及滚轮速度、滚压次数为调整参数，在人机界面上可以调整，非常方便，富有人性化，PLC内部程序是控制设备自动运行的关键部份。
