电阻点焊和缝焊机的改造,已成为当前焊接生产的主要研究课题之一,怎样进行改造?这是许多企业都在关心的问题。最近我公司从日本引进控制设备,经与老焊机配套调试和工艺试验证明,引进国外控制设备来改造国产老焊机,是目前焊机改造的一条捷径,下面介绍引进日本产CY2210恒流控制器与MTN型老焊机配套改造的效果。 1.CY2201恒流控制器的基本原理 CY2201点焊恒流控制器的控制程序简单,点焊过程中能实现自动反馈控制,使焊接电流保持恒定。其基本原理框图见图1。
Resistance spot welding and seam welding machine transformation, welding has become the current production of one of the major research topics, how to transform? This is a lot of businesses are concerned about. Recently, our company imported control equipment from Japan. After the matching with the old welding machine and the process test, it is proved that the introduction of foreign control equipment to transform the domestic old welder is a shortcut to the current welding machine transformation. The following introduces the introduction of the Japanese production CY2210 constant current control MTN-type and old welding machine supporting the transformation effect. 1.CY2201 constant current controller basic principle CY2201 spot welding constant current controller control program is simple, spot welding process can achieve automatic feedback control, so that the welding current remains constant. The basic block diagram shown in Figure 1.
