Abstract
The utility model provides a kind of special straightener of cross-shaped steel, straightening mechanism including engine base and in engine base, wherein, the straightening mechanism includes the corresponding upper straightening roll in several groups of positions and lower straightening roll, symmetrical concave structure is equipped at aligning roll gap between upper straightening roll and lower straightening roll, the shape which is formed is consistent with the shape of cross-shaped steel to be aligned；The upper straightening roll and lower straightening roll are connected by transmission mechanism with motor drive, and upper straightening roll and the straightening roll lifting axis connection in engine base, manual adjustment wheel are used to adjust the height of upper straightening roll with straightening roll lifting axis connection.The utility model is transformed straightening roll on the basis of the straightening functions such as square steel, round steel, the band steel of rule are met, and two kinds of different railway freight-car skidding beam cross-shaped steels can be aligned.
Description
Technical field
The utility model is related to a kind of special straighteners of cross-shaped steel, belong to Section Steel Production equipment technical field.
Background technology
Cross-shaped steel（Railway freight-car skidding beam）After hot rolling, different degrees of bending and torsion, shadow can be generated
Further processing is rung to use, it is necessary to be aligned.Existing roll leveller is single straightening function, is being changed without rectifying
It is poor to the leveling effect of cross-shaped steel on the premise of straight roller.
Utility model content
For above deficiency, the purpose of this utility model is to provide a kind of special straightener of cross-shaped steel, realizes not more
On the premise of changing straightening roll, irregular cross-shaped steel can be met（Railway freight-car skidding beam）Aligning.
The utility model is implemented by the following technical programs：A kind of special straightener of cross-shaped steel, including engine base and
Straightening mechanism in engine base, wherein, the straightening mechanism includes the corresponding upper straightening roll in several groups of positions and lower straightening roll,
Symmetrical concave structure is equipped at aligning roll gap between upper straightening roll and lower straightening roll, what which was formed
Shape is consistent with the shape of cross-shaped steel to be aligned；The upper straightening roll and lower straightening roll pass through transmission mechanism and motor drive
Connection, and upper straightening roll and the straightening roll lifting axis connection in engine base, manual adjustment wheel lift axis connection with straightening roll
For adjusting the height of upper straightening roll.
Preferably, the aligning roll gap becomes smaller successively according to order from front to back, it is therefore an objective to eliminate material to the greatest extent
Stress inside material.
The technique effect of the utility model：The utility model is meeting the straightening functions such as square steel, round steel, the band steel of rule
On the basis of, straightening roll is transformed, two kinds of different railway freight-car skidding beam cross-shaped steels can be aligned.
Description of the drawings
Fig. 1 is straightener direct-view figure.
Fig. 2 is aligning side view.
Fig. 3 is upper and lower straightening roll plan view.
Fig. 4 is two kinds of cross-shaped steel sectional views to be aligned.
Specific embodiment
The special straightener of a kind of cross-shaped steel as depicted in figs. 1 and 2, the straightener including engine base 1 and in engine base 1
Structure, wherein, the straightening mechanism include the corresponding upper straightening roll 7 in several groups of positions and lower straightening roll 6, upper straightening roll 7 and it is lower rectify
It is equipped with symmetrical concave structure at aligning roll gap 5 between straight roller 6, which cuts according to two kinds of cross-shaped steels
Face shape carries out concave surface processing to straightening roll, i.e., the shape that symmetrical concave structure is formed and the shape of cross-shaped steel to be aligned
Unanimously, two kinds of different models railway freight-car skidding beam cross-shaped steel provided in this embodiment, as shown in Figure 3；It is described strong
Straight roller 7 and lower straightening roll 6 are sequentially connected by transmission mechanism 9 and motor 8, and upper straightening roll 7 and rectifying in engine base 1
Straight roller lifting shaft 4 connects, and manual adjustment wheel 3 is connected to adjust the height of upper straightening roll 7, the electricity with straightening roll lifting shaft 4
Machine 8 is mounted in cement platform 10, and cement platform 10 is used to support motor 8.
Two kinds of railway freight-car skidding beam cross-shaped steels as shown in Figure 4 are when carrying out straightening operation, 7 He of upper straightening roll
Concave structure on lower straightening roll 6 is symmetrically placed, and when upper straightening roll 7 and lower straightening roll 6 close up, two kinds of cross-shaped steels can be with
It " inlays " at aligning roll gap 5, as shown in Figure 3.When in use, manual adjustment wheel 3 is first adjusted, adjusts straightening roll lifting shaft
Upper straightening roll 6 is reduced to suitable position by 4, and can meet aligning needs with lower straightening roll 7 " joint close ".It is electromechanical to start aligning
After machine 8, cross-shaped steel to be aligned is inserted by aligning roll gap 5, and cross-shaped steel will travel forward with the rotation of upper and lower straightening roll,
Then it is driven out to aligning region.In order to the internal stress of maximum elimination material, aligning roll gap 5 should be added by succession
Sternly.Cross-shaped steel is then turned and is inserted into aligning roll gap 5 and carries out if there is torsional bending phenomenon by cross-shaped steel after aligning end to end
Aligning is once, you can eliminates material major part internal stress, no longer bends, reverses.
