mf系列中頻逆變直流電阻焊接機(jī)
mf series middle frequency inverter dc welding machine
設(shè)備主要特點(diǎn)
1.電阻焊是靠焊接電流通過(guò)工件而工件本身的電阻產(chǎn)生的高溫?zé)醽?lái)熔合焊接的，因此可通過(guò)調(diào)整提高和改變焊接電流的頻率來(lái)使焊接過(guò)程更加優(yōu)化，焊接過(guò)程控制的更好，從而提高產(chǎn)品的焊接質(zhì)量。
中頻焊機(jī)就是在此原理基礎(chǔ)上研發(fā)產(chǎn)生，普通交流工頻焊機(jī)的頻率是50hz或者60hz，而中頻焊機(jī)的頻率是1000hz，時(shí)間控制精度高，功率因數(shù)達(dá)98%，無(wú)電磁感應(yīng)渦流干擾，焊接質(zhì)量相對(duì)提高很多。
2.但是并非所有工件的焊接電流**值都是1000hz，有些需要更大一些的焊接頻率，有些則需要小一些，我們公司在此基礎(chǔ)上又研發(fā)出焊接電流頻率可調(diào)可變的性能更優(yōu)良的vf系列變頻焊機(jī)。其原理是通過(guò)加有igbt的脈沖寬度可調(diào)的“焊接控制器”及輸出電壓v和變壓器匝數(shù)n可調(diào)的“焊接變壓器”一起實(shí)現(xiàn)焊接頻率可調(diào)。
3.然而這兩種焊接都不會(huì)根據(jù)工件的細(xì)微變化自動(dòng)調(diào)整焊接電流的大小，為了滿(mǎn)足汽車(chē)，飛機(jī)等高端產(chǎn)品對(duì)焊接質(zhì)量的更高需要，我們公司又在以上兩種焊機(jī)的基礎(chǔ)上加裝了“動(dòng)態(tài)電阻原理的中頻自適應(yīng)控制系統(tǒng)”，
該系統(tǒng)以恒流方式控制技術(shù)為基礎(chǔ)，根據(jù)工件板厚、工件表面污垢及銹蝕程度，操作人員個(gè)體差異性等因素的細(xì)微變化及焊點(diǎn)的分流等情況，自動(dòng)調(diào)整焊接過(guò)程中的每一個(gè)焊點(diǎn)的焊接電流，保證焊接質(zhì)量和焊接效果的高度一致性。
4.中頻電源及變頻電源都是由三相電網(wǎng)供電，而不是傳統(tǒng)的工頻交流焊機(jī)的兩相供電，不會(huì)造成電網(wǎng)的波動(dòng)，同時(shí)對(duì)電網(wǎng)自身的波動(dòng)，電壓的突然升降，適應(yīng)性也較強(qiáng)。電流輸出更**、更穩(wěn)定，更節(jié)能、更高效。
5.特別適合焊接導(dǎo)電率較高的鋁，銅材料，比較厚的工件，汽車(chē)，航天飛機(jī)，其他高端產(chǎn)品及行業(yè)的焊接。
main application and characteristic
1. resistance welding is one kind of welding technology which melt the bl material by the resistance heating energy which is generated by the welding current passing the workpiece itself.therefore by increase or adjusting the welding current frequency,it can change and improve the welding quality.
just basing on this theory,we develop the middle frequency inverter dc welding machine,its welding current frequency increase to 1000hz from common 50hz or 60hz.
the controlling time precision is much higher, the power factor is more than 98%,without eddy current electromagnetic induction interference, the welding quality is also improved a lot.
2. while not for all the workpiece,the current optimum value is all same as 1000hz,some need bigger welding frequency,others need less,just because this reason,basing on the middle frequency welding technology,we also develop vf series variable frequency welding machine which welding frequency is adjustable.
the principle is that by the added a igbt pulse b adjustable "welding controller" and the output voltage of v and transber turns n all adjustable "welding transber" to fulfill the function of adjustable frequency.
3. however, these two kinds of welding bs both can not adjust welding currecnt value of each welding automatically according to the subtle changes of workpiece.
in order to meet much higher request to welding quality,such as for the automotive,aircraft and other high-end products,we develop one kind of “dynamic resistance principle auto self adaptive control system”.it can install to both mf and vf welder,by this way they can adjust the welding current automatically basing different product.
this system is based on the constant current mode control technique, according to the workpiece thickness,different dirt surface of workpiece and the corrosion degree,current shunt,the operator’s individual difference factors,such as the subtle changes and solder joints, it can automatically adjust welding current during the welding process of each welding spot,ensure the consistency of the welding quality and effect.
4. middle frequency and variable frequency welder are both powered by three-phase power,compared to the traditional ac welder two-phase power supply,will not cause the fluctuation of power supply, also can adapt suddenly lifting voltage strongly.current output is also more accurate, more stable, more energy saving and more efficient.
5. these kinds of higher technology is specially suitable for welding higher conductive rate of material,such as aluminum,copper,silver,and so on. also good at welding much more thicker workpiece,automobile,aerospace,and other high request products and industry.
