电气系统

Electrical System

电气系统包括焊接主电路和控制电路。

Electrical system includes welding main circuit and control circuit.

(1)焊接主电路由主开关QS、晶闸管开关KP和变压器TC3等组成。主开关QS用于接通和切断焊接回路供电电源，当调整变压器级数或焊机长期不用时，应断开QS。晶闸管开关在焊机工作时用于接通或关断焊接电源。变压器TC3用于提供不同电压级别的焊接电压，共8级。

Welding main circuit is composed of the main switch QS, thyristor switch KP and transformer TC3. The main switch QS is used for switch-on and turn-off the power supply of welding circuit, it shall be turn off if adjust welding transformer series or long time on use. The thyristor switch KP is used for switch-on or turn-off the welding power when welder is running. The transformer TC3 is used for supplying different welding voltage which is total 8 series for this model.

(2)控制电路由PLC的输入/输出电路、操作件、触摸屏等组成。PLC是控制电路的核心，焊机按PLC的程序工作，旋转编码器经齿轮齿条与动板相接，用于检测动板的位移，其精度为35脉冲/mm。PLC根据脉冲信号控制动板的变速和换向，触摸屏用于监视焊机工作，并可按要求修改参数。

Control circuit is composed of PLC input/output circuit, operation element and touch screen etc. The PLC is the core of control circuit, and the welder will run according to the programs of PLC. The rotary encoder is connected with movable plate through pinion and rack which is used to detect displacement of movable plate, with accuracy of 35pulse/mm. PLC will control the speed and reversing of movable plate according to the pulse signal. Touch screen is used to monitor welding operation, amend parameter in line with welding requirements.

液压系统

Hydraulic System

液压系统由液压站、管路和主机上的油缸、阀等组成。液压站用于提供系统压力。主机上的阀组用于控制各油缸的工作，其中顶锻压力、夹紧压力、预热压力均可单独调节，并有压力表显示调节值，在顶锻油缸装有一杠杆调节阀，用于调节动板向前时的速度。

、The hydraulic system is composed of hydraulic station, piping, oil cylinder and valve of host. Hydraulic station supplies the system pressure. The valves of host control the oil cylinders. The upsetting pressure, clamping pressure and pre-heating pressure can be adjusted separately which display the adjustment value by pressure gauge. And the upsetting oil cylinder is equipped with a lever regulating valve which is used for adjusting the forward speed of movable plate.
