SYT-MD-40

產(chǎn)品概述

該系列焊機(jī)是一夽先進(jìn)的焊接設(shè)備。應(yīng)用廣泛，焊接變壓器體積小而輸出能量大，三相交流電經(jīng)整流后轉(zhuǎn)換成為直流，再經(jīng)由IGBT組成的逆變電路逆變成為中頻1000HZ方波接入焊接變壓器的初級(jí)，經(jīng)焊接變壓器降壓整流成為脈動(dòng)很小的直流電供給電極對(duì)工件進(jìn)行焊接。逆變器通過(guò)反饋回來(lái)初級(jí)或者次級(jí)焊接電流進(jìn)行調(diào)整IGBT的占空比，從而達(dá)到焊接過(guò)程恒流的效果。

Description

Medium frequency inverter spot welding machine is an　advanced　welding　machine　wide　application．The　welding　transformer　is　in　small　size　but　the　output　energy　is　large．Three－phaseＡＣwill　be　converted intoDCafter　being　rectfied。Then theDC will be converted into medium frequency1000Hz square wave to be connected to　primary　welding　transformer　through　the inverter　circuit　which　is　composed　of　LGBT．The?。停啤quare　wave　will　become　small　pulseＤＣto　the　electrode　for　welding　work　Piece　through　the　depressurization　and　rectifying process in the　welding　transformer．The inverter　will　adjust　the duty　ratio of　IGBT　through　the feedback　primary　or　secondary　current so as to achieve current of the welding process．

性能特點(diǎn)

１.    二次焊接回路中流過(guò)的電流是直流，因此由于深入焊接工件中不同的次級(jí)長(zhǎng)度而產(chǎn)生的二次回路中的感抗對(duì)焊接電流的影響大大減小。

２.    三相平衡負(fù)載，減少對(duì)供電系統(tǒng)功率要求，功率因素接近１，無(wú)電感分量，無(wú)須調(diào)整功率因素。

３.    消除對(duì)供電電源的污染，屬綠色焊接，不必單獨(dú)提供電源可以和機(jī)器人焊接工裝控制系統(tǒng)在鏈接使用。

４.    減少電源消耗，節(jié)能降耗，還能減少電纜的需要和花費(fèi)及大量的維護(hù)成本。

５.    焊接變壓器的質(zhì)量大大減輕，輕便快捷，只有交流變壓器的質(zhì)量和體積的１／３，適用于機(jī)器人焊接系統(tǒng)。

６.    提高熱量輸入效率，焊接變壓器輸出的是直流電壓，沒(méi)有電感的煩擾，純直流電路沒(méi)有過(guò)零的缺點(diǎn)，熱量的效率大大提高。

７.    智能型數(shù)字全閉環(huán)控制，焊接控制電流更精確，調(diào)整精度和監(jiān)視精度比AC系統(tǒng)高２０倍?？梢詫?duì)逆變器和變壓器進(jìn)行保護(hù)。

８.    增加焊接工藝的穩(wěn)定性，直流焊接的工藝性好，焊接參數(shù)的可適應(yīng)范圍寬，次級(jí)電流可以真正保持恒流，比交流要有更廣泛使用的前景。

９.    數(shù)字化控制更加提高電流控制和測(cè)量精度，焊接時(shí)間精度為毫秒，可以對(duì)焊接的時(shí)間任意控制。

１０. 可以焊接鋁和鍍鋅金屬等材料，焊接結(jié)果良好。

１１. 尤其適合于三層板焊接、非常薄的材料的焊接以及精密焊接的要求。

１２. 精密逆變直流電流電阻焊，逆變頻率更高，電流控制更精確。

Features

１.    The current in secondary welding loop is DC.Dramatically reduce the impact to the welding current due to　the　inductive　reactance　in　secondary　loop　when　conducting　welding　to　the　work　piece．

２.    Three-phase　balanced　load　can reduce the requirement to the power supply system.The power factr is close to1.No electrical inductance,so no need to adjust the power factor.

３.    Eradicate the contamination to the power supply. Lt is a kind of environmentally friendly welding method.No need to provide power independently.lt is able to be used together with robotic welding ssystem.

４.    Reduce power consumption,energy saving.Reduce the requirement of cables and lots of maintenance cost.

５.    The weight of transformer is reduced greatly .lt is light and convenient.The weight and size of the MF transformer is only1/3 of theAC type transformer. Suitable for robot welding system.

６.  lncrease the heat input efficiency.The output of welding transformer isDC voltage,without the disturbance of inductance.Pure DC has no defect of zero passage.The efficiency of heat is enhanced dramatically.

７.  Lntelligent digital full-closed loop control.The welding control current will be more precise.The adjustment precision and monitoring precision is20 times higher than theAC system.Be able to protect the inverter and transformer.

８.  Lncrease the stability of the welding technology.DCwelding technology is good and the welding parameters are of wide application.The secondary current could achieve actual constant current.Have better using prospect thanAC.

９.   Digital control can better improve the current control and measurement accuracy.The welding time precision is ms which can help you control the welding time at random.

１０.         Be able to weld aluminum and galvanized metal with good weling quality.

１１.         Especially suitable for welding three-layer metal sheet or very thin material and precision welding requirement.

１２.         Precision inverterDCresistance welding.Higher inverter frequency,more accurate control of the current.
