The square or rectangular shaping is formed out before the tube welding, with important advantages in terms of power and material cost reduction.
Detail
Double cantilever gear drives, the producing width of machine is adjust continually, it is possible to change the width and height.
Adopts separated stander, machine base adopts welded structure, feeding and guiding device goes through distressing dealing; fine carbon steel roller shaft; with strengthener to make sure the products' precision.
The Slitting Line is used to slit the steel strip in coil into several narrow strips of certain size. The slit strips are then rewound into coils, from which welded pipes, cold-formed sections and presswork are manufactured.
The Cut To Length Line used for processing cold rolled and hot rolled carbon steel, silicon steel, tinplate, stainless steel and other different kinds of surface plated metal.
The accumulator is installed between the shear & welder and the forming line. Its purpose is to give enough time for feeding the new coil from uncoiler to shear & welder and for the shear & welder to cut and join front end of the new coil with tail end of previous coil.
Rolls are manufactured out of AISI D2, D3 or equivalent steel. Material is annealed, hardened and tempered to get hardness of 60 ± 2 HRC. Rolls profiles are precisely turned at high speed on CNC Turning machine using ceramic tips to get the desired surface finish.
