Continuous cold bending roll forming machine is actually a series of horizontal roller and vertical roll two-high rolling mill of alternative arrangement.Forming pattern number depends on steel pipe specification and material, generally for 5 ~ 12.
According to the forming roll on the rack installation fixed way is different, can be divided into the cantilever horizontal roller frame and gantry type, cantilever type forming machine structure is compact, roll change is convenient, but less stiffness, fluctuations in the product dimension tolerance is big, therefore only suitable for ∅ 56 mm below the production of small diameter thin wall pipe;Gantry forming machine is the reverse of cantilever, its stiffness, easy installation between frame fixed guide, product size precision, tolerance is small, but the structure is complex, roll change time consuming, and are now using the method of forming roll pre-installed overall change stand, so you must at least have a spare frame, its broad scope, tube welding ∅ 6 ~ 426 mm in diameter, can even be greater than the ∅ 660 mm diameter welded pipe.Cold roll forming machine in the aspect of structure is in constant improvement and perfect.In the new scheme, not all level high stand, transmission roller drive level under the roller and only first, seven, eight stand on the roller, thus more conducive to deformation and reduce the forming roll wear and tear.In addition, the new continuous cold bending roll forming machine adopts hydraulic motor drive and quick roll change device, greatly reduce the roll change time change specifications.
