Summary of the invention

In order to solve the prior art problem, to the drawback of above processing method, the present invention provides a kind of method of practicing thrift the machined steel section bar of cost, environmental protection.

The processing method of a kind of steel profile provided by the invention comprises processing steps such as the uncoiling of band coil of strip, smoothing, sanding, paint roller coating, oven dry, roller moulding, length shearing, finished product stacking, and is specific as follows:

(1) uncoiling: behind the raw material band coil of strip material loading with the machined steel section bar, through uncoiler the band coil of strip is carried out uncoiling and handle, obtain long and narrow steel band;

(2) smoothing: the long and narrow steel band that step (1) is obtained uses levelling machine to smooth processing;

(3) sanding: the steel band after the smoothing in the step (2) is carried out the ball blast sanding with sand shaker handle;

(4) paint roller coating: the steel band after the processing of step (3) sanding is carried out surface paint roller coating through coating roller;

(5) oven dry: the steel band after the paint roller coating that step (4) is obtained gets into the drying room oven dry;

(6) roller moulding: the steel band after the oven dry that step (5) is obtained is through the moulding of roller machine roller;

(7) length is sheared: the steel profile after step (6) the roller moulding is carried out cut-to-length by cutter;

(8) finished product stacking: the typing workpiece after step (7) shearing is used the piling bed stacking.

Among the present invention, the coating roller that uses in the step (4) is single face coating roller or two-sided coating roller.

Among the present invention, during step (6) middle roller moulding, process the profile member of various different cross section shapes.

The manufacturing approach of steel profile can be widely used in the fields such as automobile making, building and container manufacturing among the present invention.

Among the present invention, because steel band is a sanding under the dull and stereotyped state, so cover than being easier to; Thereby can reduce the ramming head quantity of sanding, generally can reduce the ramming head more than 40%, this has just reduced the input of equipment; Energy consumption when having reduced the equipment operation has also alleviated the pressure of dedusting.Simultaneously, because workpiece is to carry out paint application at dull and stereotyped state, so can use the method for roller coating; And the paint roller coating can be basically without diluent; The basic not waste of paint, general paint can reduce more than 80% with the amount ratio method for paint spraying of diluent, and the amount ratio method for paint spraying of paint can reduce about 40%; Simultaneously because dirty treatment facility is not just coated with lacquer in the dirty generation of lacquer yet.Thereby reduced pollution, reduced equipment investment, improved workman's work situation environment.
