技術(shù)特色

閃光對焊機(jī)是車輪輪輞焊接的專用設(shè)備，焊接參數(shù)由觸摸屏設(shè)定，自動(dòng)化程度高、工作可靠、調(diào)整方便等特點(diǎn)。有效解決了高強(qiáng)板焊接牢固及焊口強(qiáng)度。

智能化：由伺服閥控制頻閃燒化的過程，使焊接穩(wěn)定，響應(yīng)速度快。針對厚度不同的輪輞，可以選擇相應(yīng)的焊接檔位。

發(fā)展方向：實(shí)現(xiàn)無人化生產(chǎn)，組件自動(dòng)上下料機(jī)構(gòu)，實(shí)現(xiàn)相應(yīng)配套。

電氣系統(tǒng)

Electrical System

電氣系統(tǒng)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(guān)QS、晶閘管開關(guān)KP和變壓器TC3等組成。主開關(guān)QS用于接通和切斷焊接回路供電電源，當(dāng)調(diào)整變壓器級數(shù)或焊機(jī)長期不用時(shí)，應(yīng)斷開QS。晶閘管開關(guān)在焊機(jī)工作時(shí)用于接通或關(guān)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(jī)按PLC的程序工作，旋轉(zhuǎn)編碼器經(jīng)齒輪齒條與動(dòng)板相接，用于檢測動(dòng)板的位移，其精度為35脈沖/mm。PLC根據(jù)脈沖信號控制動(dòng)板的變速和換向，觸摸屏用于監(jiān)視焊機(jī)工作，并可按要求修改參數(shù)。

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(tǒng)

Hydraulic System

液壓系統(tǒng)由液壓站、管路和主機(jī)上的油缸、閥等組成。液壓站用于提供系統(tǒng)壓力。主機(jī)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(yù)熱壓力均可單獨(dú)調(diào)節(jié)，并有壓力表顯示調(diào)節(jié)值，在頂鍛油缸裝有一杠桿調(diào)節(jié)閥，用于調(diào)節(jié)動(dòng)板向前時(shí)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.
