The spot welder system consists of three parts: mechanical device, power supply device and control device. In order to meet the requirements of the welding process, the welding mechanism (welding tongs) adopts a two-stroke fast pneumatic transmission mechanism. By changing the opening of the welding tongs by switching the stroke control handle, it can be divided into large opening and small opening to meet the welding operation requirements. The normal state is that the welding tongs are opened for a short stroke. When the control button is switched to the "energized" position, the handle switch is clamped and the welding tongs are clamped and pressurized, and the current is restored to the short stroke after completing a welding cycle under the control of the control system. Open state.
Power supply unit
The main power circuit is composed of a resistance welding transformer, a thyristor unit, a main power switch, a welding circuit and the like. At present, the welding equipment we use is a single-phase power frequency AC resistance welder with a power of 200kVA and a secondary output voltage of 20V--40V. Due to the collinear production of various models, the welding tongs are to be welded with high-strength steel and low-carbon steel sheets. The welding tongs must transmit large mechanical force and welding current. Therefore, the strength, rigidity and heat of the welding tongs must meet certain requirements. And to have good electrical and thermal conductivity, and at the same time requires the welding tongs to use water cooling, so choose the welding tongs electrode arm can withstand 400kg pressure of the new welding tongs.
Control device
The control device mainly provides signal control resistance welder action to turn on and off the welding current, control the welding current value, and perform fault monitoring and processing.
