Description

一种逆变数字化多功能焊机 技术领域
本实用新型涉及焊接设备领域，具体为一种逆变数字化多功能焊机。
背景技术
焊接：也称作熔接、镕接，是一种以加热、高温或者高压的方式接合金属或其他热塑性材料如塑料的制造工艺及技术。焊接通过下列三种途径达成接合的目的：
1、熔焊——加热欲接合之工件使之局部熔化形成熔池，熔池冷却凝固后便接合，必要时可加入熔填物辅助；
2、压焊——焊接过程必须对焊件施加压力；
3、钎焊——采用比母材熔点低的金属材料做钎料，利用液态钎料润湿母材，填充间隙，并与母材互相扩散实现链接焊件。
焊机就是为焊接提供一定特性的电源的电器，焊接由于灵活简单方便牢固可靠，焊接后甚至与母材同等强度的优点广泛用于各个工业领域，如航空航天，船舶，汽车，容器等。
电焊机实际上就是具有下降外特性的变压器，将220V和380V交流电变为低压的直流电，电焊机一般按输出电源种类可分为两种，一种是交流电源的；一种是直流电的。直流的电焊机可以说也是一个大功率的整流器，分正负极，交流电输入时，经变压器变压后，再由整流器整流，然后输出具有下降外特性的电源，输出端在接通和断开时会产生巨大的电压变化，两极在瞬间短路时引燃电弧，利用产生的电弧来熔化电焊条和焊材，冷却后来达到使它们结合的目的。焊接变压器有自身的特点，外特性就是在焊条引燃后电压急剧下降的特性。
传统的焊机在操作过程中需要提供稳定的电压，当电压有轻微变化时则会导致这个焊机系统由于误判而断电，同时传统的焊机只针对特定的丝盘，在应用过程中造成了一定的局限性。
