自动焊接专机的电气系统介绍

来源:http://www.tayfsk.com/  发布时间:2021-03-24 浏览次数:

自动焊接专机是用于自动化生产的,要求人工或者机械手上下工件,焊接工装夹具自动将工件固定,定位,自动启动焊接电源的电弧,自动送丝和焊枪或工件的自动移动,焊接完成后自动退回,人工或机械手取下工件,其组成主要由焊接系统、机械系统、电气控制系统构成。

Automatic welding machine is used for automatic production, which requires manual or manipulator to move up and down the workpiece, welding fixture to automatically fix and position the workpiece, automatically start the arc of welding power, automatically feed wire and move the welding gun or workpiece, automatically return after welding, and manually or manipulator to take down the workpiece. It is mainly composed of welding system, mechanical system and electrical control System composition.

电气控制系统主要控制夹具的装夹和定位,焊机的启动和停止,焊枪或工件的运动,输送装置的进出等等。含自动/手动转换,收弧有无控制,焊接速度的调整和显示,焊接电源的开关及急停开关等。
The electrical control system mainly controls the clamping and positioning of the fixture, the start and stop of the welding machine, the movement of the welding gun or workpiece, the in and out of the conveying device, etc. Including automatic / manual conversion, arc control, welding speed adjustment and display, welding power switch and emergency stop switch, etc.

电气控制系统一般由继电器、PLC可编程控制器、单片机、数控系统、计算机控制。在焊接生产现场,由于焊接飞溅多,水电气线路复杂,电磁干扰大,所以最常使用的继电器、PLC、数控系统。而PLC由于兼顾了继电器的功能,又可以实现编程控制。
Electrical control system is generally controlled by relay, PLC programmable controller, single chip microcomputer, numerical control system and computer. In the welding production site, because of the welding spatter, water and electrical circuit complex, electromagnetic interference, so the most commonly used relay, PLC, CNC system. PLC can realize programming control because it takes into account the function of relay.
随着技术的发展和新产品的出现,现在的PLC还能实现更加复杂的功能,如部分数控功能,如圆弧插补等。所以PLC控制技术在自动焊接专机里得到了最广泛的应用。
With the development of technology and the emergence of new products, now PLC can achieve more complex functions, such as some CNC functions, such as arc interpolation. So PLC control technology in automatic welding machine has been the most widely used.
