Problems solved by technology

[0002] Flash butt welding is widely used in the longitudinal connection of steel bars and the welding of prestressed steel bars and screw end rods. The principle of flash butt welding of steel bars is to use a butt welding machine to make the two ends of the steel bars contact. After softening at a certain temperature, carry out axial pressure upsetting to form a butt welded joint. Continuous flash welding, preheating flash welding and flash-preheating-flash welding are commonly used in the flash butt welding process of steel bars. Afterwards, heat treatment is carried out with electricity, but the current flash butt welding machine may have sparks splashing during the welding process, which will cause damage to the staff. Compared with the design provided by the application number 201721801446. Welding, but this design cannot completely cover the sparks during welding, which is easy to cause sparks to splash forward

Abstract

The invention discloses a flash butt welding machine with a safety shield. The flash butt welding machine with the safety shield comprises a base and a power unit; wherein an impurity holding groove is formed in the upper side of the base, an auxiliary support rod is fixed in the impurity holding groove, and a welding machine main body is fixed at the upper side of the base; two fixed bases are fixed at the upper side of the base, the welding machine main body is located between the two fixed bases, and two outer baffle frames are fixed at the upper side of the base; an inner attached frame isfixed between the lower ends of the sides of the two outer baffle frames closed to each other, an outer attached frame is fixed between the upper ends of the sides of the two outer baffle frames closed to each other, the inner frame is located in the outer frame, and middle attached frame is movably inserted between the inner attached frame and the outer attached frame. The flash butt welding machine with the safety shield can fix welded parts conveniently and firstly; and when welding the welded parts, a protective cover is used to cover a welding place completely to avoid spark splash, protect an operator, reduce the risk of work and collect impurities after welding.
