電氣系統

Electrical System

電氣系統包括焊接主電路和控制電路。

Electrical system includes welding main circuit and control circuit.

(1)焊接主電路由主開關QS、晶閘管開關KP和變壓器TC3等組成。主開關QS用于接通和切斷焊接回路供電電源，當調整變壓器級數或焊機長期不用時，應斷開QS。晶閘管開關在焊機工作時用于接通或關斷焊接電源。變壓器TC3用于提供不同電壓級別的焊接電壓，共8級。

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)控制電路由PLC的輸入/輸出電路、操作件、觸摸屏等組成。PLC是控制電路的核心，焊機按PLC的程序工作，旋轉編碼器經齒輪齒條與動板相接，用于檢測動板的位移，其精度為35脈沖/mm。PLC根據脈沖信號控制動板的變速和換向，觸摸屏用于監視焊機工作，并可按要求修改參數。

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.

液壓系統

Hydraulic System

液壓系統由液壓站、管路和主機上的油缸、閥等組成。液壓站用于提供系統壓力。主機上的閥組用于控制各油缸的工作，其中頂鍛壓力、夾緊壓力、預熱壓力均可單獨調節，并有壓力表顯示調節值，在頂鍛油缸裝有一杠桿調節閥，用于調節動板向前時的速度。

、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.
