Flash Butt Welding Machine for Rebar Small Resistance Wire Joint Machine

Flash butt welding machine for rebar small resistance wire joint machine
Structure and working principle of butt welding machine
1,Construction The welding machine is mainly composed of welding transformer, left electrode, right electrode, AC contactor, feeding mechanism and control elements.
The feeding mechanism is to realize the melting and extrusion process required in the welding process, it mainly includes dry in the tank, sliding plate and adjusting screw. The maximum working stroke of the electrode can be obtained when the joystick is moved in a two-stage limit position.
The control of the element is programmed by pressing the contactor button, which turns on the relay and causes the AC contactor to act, so the welding transformer is Turn on. Move the lever so that the two welding parts are pressed tightly, and power heating.
2,Working principle. The electrodes of the butt welding machine are mounted on the fixed plate and the sliding plate, the sliding plate can be moved along the rail on the body, the current is passed through the transformer and the electrodes can be moved on the sliding plate. secondary coils to the electrodes, which, when the pushing pressure mechanism brings the two bar ends together, causes a short-circuit resistance to generate heat. Heat the ends of the bar, and when heated to high plasticity, squeeze with additional force to achieve a firm butt at both ends.
