METHOD OF MANUFACTURE OF CHANNELED PROFILES AND PROFILE MILL FOR ITS REALISATION Russian patent published in 2008 - IPC B21D5/06 

FIELD: technological processes.

SUBSTANCE: shape direct channeled profiles on a strip consequently to transitions with flat sites between them. On last transition the cross-section corrugations are shaped on flat sites between direct corrugations with alternate step on all width of a profile. The profile mill contains two-high stands sequentially located on a bed work with calibers of the main instrument. Calibers of the stands on the first transitions are executed in the form of the packages containing the upper and lower main rollers, established between two pairs of the upper and lower gauging rollers. Packages in the stands are established due to amount of corrugations and linked among themselves with corresponding distant sleeve in each subsequent stand. The caliber of the stand of last transition is executed in the form of rollers placed on all length, a set from the upper and lower first gauging rollers established with step direct corrugations, and from the upper and lower second gauging rollers established between the first gauging rollers. Thus the upper second gauging rollers have built in two main punches, and the lower second gauging rollers have round-nose grooves corresponding to punches. The upper roller of the last stand it is driven, and its rotation is synchronised with rotation of the lower roller due to gear, the lower rollers are linked with a drive.

EFFECT: increased assortment of the profiles produced due to obtaining of a new relief of a profile.
