20m/Min 12mm Water Down HRC Steel Pipe Production Line

Specification

LW1000-12 multi-functional cold bending steel welded pipe units

1,The production process introduction

LW1000-12 cold bending steel welded pipe production line, the production line to meet opening cold bend steel, square rectangle tube production process requirements.In hot rolled strip steel as raw material, through the method of cold bending forming and high frequency welding production required specifications of the opening cold bend steel, square,rectangle pipe and round pipe.Reproduction of a complete set of unit when opening cold bend steel rectangular pipe and adopts the most advanced international level of multipoint to combined bending, pipe when using popular titles include FFX forming technology in production.These two forming modes of deformation process make a force more reasonable, the unit of each frame material deformation by the original line contact into point contact.Two forming modes are used the world's advanced technology and the organic combination of both ,as also the cold bending steel and welding pipe technology product requirement.

Full unit set of significant features:
(1) square rectangle pipe and opening cold bend steel using a multipoint to bending roll, the round pipe in rough shape closed before using a set of popular titles include FFX forming roll ,the roll above the set without replacement, reduce the roll cost more than 90%.
(2) the unit each frame of the deformation of material section by a line contact into contacts the whole unit to reduce energy consumption by over 30%.Save the strip width 2.3 ~ 2.5%.

2, The control scheme introduction
Cold bending steel welded pipe production line normally need each single equipment, uncoiling, leveling, shearing butt welding, looping, forming, welding, sizing, high frequency, power, speed control cabinet, flying saw, chain control table, platform, etc.Speed and stable operation, achieve the goal of the normal production.
Every stand-alone equipment equipped with control work station, to the corresponding equipment start-stop, adjusted speed running state, two or more interfaces, and obligate output two passive contact, will run or fault signal, the signal to the work station and PLC system at the same time, set the emergency button on the operating table, in the loop, high frequency, flying saw, such as joint fault, any emergency button operation across the park.
