Processing device for shearing welded steel pipe

The invention relates to the technical field of steel pipe processing equipment, in particular to a processing device for shearing welded steel pipes. The processing device comprises a base, upright posts are symmetrically and fixedly connected to the surface of the base, a cross beam is fixedly connected to the end parts of the upright posts, and an air cylinder is fixedly connected to the bottomsurface of the cross beam and is connected with a connecting piece; and the connecting piece is fixedly connected with a protective cover, and the protective cover is rotatably connected with a knifeflywheel. The processing device solves the problems that according to an existing shearing machining device for welded steel pipes, the clamping effect is not ideal, a clamp is prone to breakage, theproduction efficiency of companies is seriously affected, and the production cost is greatly improved, and the processing device is reasonable in structural design, and convenient to use, improves the clamping effect, reduces
