When the cutting cylinder moves to the upper side of the copper strip, the cutting cylinder is activated to drive the cutting knife along the The upper side of the copper strip is moved to remove bumps on the copper strip caused by high temperature.

The present invention further provides that: a leveling cylinder is arranged on one side of the frame, the leveling cylinder is connected with a concave plate, the concave plate is clamped with a connecting rod, and the connecting rod is sleeved with a leveling roller.

By adopting the above technical solution, the leveling cylinder is activated to drive the concave plate to move and then the connecting rod to move. The movement of the connecting rod can drive the leveling roller to roll on the top of the copper strip. Due to the unevenness of the welding seam, the surface of the copper strip can be increased. flatness.

To sum up, the present invention has the following beneficial effects:

The DC current passes through the rare earth copper welding wheel and the rare earth copper electrode strip to form a short-circuit current, which causes an instantaneous high temperature between the overlapped stainless steel strips, and the two copper strips are placed between the two stainless steel strips. The materials will be welded together due to high temperature, so as to achieve the purpose of copper strip welding. The rare earth copper welding wheel moves along the length direction of the rare earth copper electrode strip. After the rare earth copper welding wheel passes, the two copper strips on the path move. will be welded together to complete the welding of the two copper strips.
