Abstract

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 impact on the clamp, eliminates stress concentration points of the device, avoids clamp breakage, improves the working efficiency, reduces the production cost and improves the economic benefits of enterprises when used for shearing the welded steel pipes.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing equipment, in particular to a processing device for shearing welded steel pipes. Background technique [0002] Steel pipes have a hollow section whose length is much greater than the diameter or circumference of steel. According to the cross-sectional shape, it can be divided into round, square, rectangular and special-shaped steel pipes; according to the production process, it can be divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot rolling and cold rolling (drawing), and welded steel pipes are divided into straight seam Welded steel pipes and spiral seam welded steel pipes. The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports c...
