Abstract
The utility model belongs to an improvement on a K2 gate outlet guide structure of a rough rolling mill used in a multi-line slit rolling process adopted in round steel bar rolling production, and particularly provides a torsional guide for round steel bar slit rolling. The torsional guide comprises a torsional guide wheel, wherein an elliptical groove-shaped wheel groove is formed in a wheel surface of the cylindrical torsional guide wheel; the circular arc radius R1 of the elliptical groove-shaped wheel groove ranges from 13.5 to 14.7 mm; the depth H of the elliptical groove-shaped wheel groove ranges from 2.5 to 3.5 mm; the intersection between the upper end of the elliptical groove-shaped wheel groove and the cylindrical surface of the torsional guide wheel adopts circular arc transition; and the circular arc radius R2 of the intersection ranges from 4.8 to 5.2 mm. The torsional guide has the advantages that the requirements of round steel bar production can be met; the rolling stability is high; the torsional accuracy of a rolled piece is improved; the torsional angle of the rolled piece is controlled effectively; the steel piling up accidents is reduced; and the yield is improved.
Description
Technical field
The utility model belongs in the multi wire cutting rolling technology of milling round steel production employing, the improvement of roughing milling train K2 passage outlet guide structure, and particularly a kind of Round Steel Slit Rolling is reversed guide and guard.
Background technology
Present domestic screw-thread steel is produced widespread usage multi wire cutting rolling technology, and the flat upright convertible milling train of finish rolling employing, and K2 passage outlet guide generally is designed to reverse guide wheel.Exploitation round steel multi wire cutting rolling; Because the K2 pass is different from screw-thread steel; It reverses the accurate torsion angle that guide and guard can not be satisfied oval rolled piece, and red changes greatlyyer parallel reverse in the guide wheel, wherein have a rolled piece torsional deflection to occur when four lines are rolling; Rolled piece is frequently piled steel before promptly causing finished product, needs a kind of guide wheel that reverses that is exclusively used in round steel cutting technology of design.
Summary of the invention
The purpose of the utility model is to provide a kind of Round Steel Slit Rolling to reverse guide and guard, can satisfy the requirement that round steel is produced, and rolling good stability improves the precision of reversing of rolled piece, and the rolled piece windup-degree is effectively controlled, and reduces heap steel accident, improves lumber recovery.
The purpose of the utility model is achieved in that a kind of Round Steel Slit Rolling reverses guide and guard, comprises and reverses guide wheel, the race of oval flute profile is being set, the arc radius R of oval flute profile race on the cylindric wheel face that reverses guide wheel
1Be 13.5-14.7mm, the depth H of oval flute profile race is 2.5-3.5mm, and oval flute profile race upper end is an arc transition with the intersection, the face of cylinder of reversing guide wheel, the arc radius R at this place
2Be 4.8-5.2mm.
Screw-thread steel K2 shape of rolling piece and reverse situation, because the parallel-segment effect of pass bottom land, it reverses introduction and is designed to the column guide wheel, its torsion angle can be according to α=π (L-(l
1-l
2)) the 2L setting, rolled piece is 90 ° of in stable condition operations when getting into the K1 clamping plate.But K2 rolled piece and guide wheel grip rolled piece torsion angle are 3 ° during round rolling; Rolling situation is following: K2 is an elliptical rolled piece; Though when windup-degree accurately calculates entering K1 clamping plate according to theoretical formula in reversing guide wheel is vertical condition of such, same under the condition of the gap of 0.6mm, rolled piece rotates rotating freely for angles and reaches 12 °; Rolled piece might the steel accident must occur frequently piling to get into clamping plate for 45 ° less than horizontal sextant angle in this scope.The utility model is designed to oval flute profile race with guide wheel; Its arc radius is less than the arc radius of rolled piece 14.8mm; The upper surface and intersection, the guide wheel face of cylinder transition arc R5mm circular arc of the oval race of guide wheel are helped four diagonal angles of rolled piece; Grip reaches the effect of screw-thread steel under the identical gap, and the torsion angle of round steel rolled piece is controlled at about 3 °, and the rolled piece windup-degree is effectively controlled.The utility model has satisfied the requirement that round steel is produced, and rolling good stability has improved the precision of reversing of rolled piece, and the rolled piece windup-degree is effectively controlled, and has reduced heap steel accident, has improved lumber recovery.
