我所设计的KD—500型点焊机同期控制箱由华东光学仪器厂试制。经过用户试用和生产考验,已于81年5月下旬正式通过鉴定,并由该厂投入生产。一、电路的特点该控制箱用于控制气压或液压传动的200 KVA及以下的单相交流点焊机,它对焊机有如下的控制作用: (一)实现点焊各工序(加压、焊接、维持、停息)无触点地自动转换; (二)根据焊接规范的要求,对各工序的时期分别进行调节; (三)在焊接工序时间内,通过对可控硅管触发相位调节,可实现对焊接热量的均匀调 I designed KD-500 spot welding control box by the East China Optical Instrument Factory trial production. After user trial and production test, it has passed the appraisal in late May, 2001 and put into production by the factory. First, the circuit features The control box for the control of pressure or hydraulic transmission of 200 KVA and below the single-phase AC spot welder, which has the following control of the welding machine: (A) to achieve the spot welding processes (pressure, Welding, maintenance, rest) non-contact automatic conversion; (two) according to the requirements of the welding specifications, respectively, during the adjustment of the process; (three) during the welding process, through the thyristor trigger phase adjustment, Can achieve uniform heat transfer welding
