Description

Prevent the kink understructure of strip running deviation
Technical field
The utility model belongs to the steel rolling hot-rolling finishing mill operation of rolling and prevents the device with steel sideslip in frame, particularly prevents the kink understructure of strip running deviation.
Background technology
Be applied in the hot-rolling finishing mill operation of rolling at present and prevent to mainly contain vertical miller, these devices of flipper guide with steel device of sideslip in frame, these apparatus features all are before the band steel gets into milling train, to realize that the pilot tape steel gets into position accurately in advance.After the band steel gets into finishing mill because of the influence of each side factors such as milling train tilt quantity, the actual wedge shape of band steel cause in milling train, sideslip taking place with steel after just the device that does not have the correction effect dynamically accomplish the function that the band steel of sideslip is rectified a deviation, can cause rolling steel scrap accident generation after the appearance of this situation and be with gad shape greatly, glacing flatness, protrudingly all wait control of index of quality to be affected and restrict.
Summary of the invention
The purpose of the utility model is to provide a kind of kink understructure that prevents strip running deviation; Its frame for movement is simple, reasonable, and reliable working operation can realize the function that loop back roll laterally moves along axis direction; Play the dynamically effect of correction continuously; Prevent to improve the quality of products, reduce the generation of steel scrap accident with the problem of steel sideslip behind the finishing mill inner-threading.
The purpose of the utility model is achieved in that a kind of kink understructure that prevents strip running deviation; Comprise and be installed in two loop back rolls between the finishing mill; T shape guide groove is being set on its side of the beam base between two finishing mills; Shape of cross section is that the crossbeam of T shape matches with the T shape guide groove of beam base, affixed oil cylinder on the bearing that the beam base left end is provided with, and the oil cylinder piston boom end is connected with the left end of crossbeam; The left and right side kink arm of articulated two symmetries on the outer face of the T shape crossbeam that stretches out beam base T shape guide groove two ends; Affixed respectively left and right bearing block is installed with loop back roll through left and right bearing block in the outer end of left and right side kink arm, is installing two hoist cylinder bases of symmetry respectively at the two ends, bottom of crossbeam; Two hoist cylinders of the articulated symmetry of difference on two hoist cylinder bases of symmetry, two hoist cylinder piston rod ends of symmetry are hinged on respectively on the corresponding kink arm.
When the utility model device uses; After two adjacent finishing mill frames are passed by band steel toe portion; Between formation tension force effect lower roll surface between frame and band steel, formed the frictional force effect with band steel after the loop back roll fast rise; Act on the band steel cross section that causes because of various factors and make loop back roll when the direction of strip running deviation moves under the effect of power of loop back roll axis direction; Because of loop back roll is installed on the crossbeam through kink arm and bearing block; When strip running deviation, need realize the time spent is done in the correction of band steel, can drive crossbeam through the action that is installed in the oil cylinder between frame and the crossbeam and laterally move, thereby realize crossbeam is driven loop back roll along the traversing function of axis direction along the center line of loop back roll axial direction is next through the horizontal shift action of loop back roll; Finally realized the correction effect of loop back roll, the complex mechanical construction that has needed when having avoided loop back roll on the kink arm, laterally to move to sideslip band steel.
The utility model is simple in structure; The style of work that the thematic structure that does not need significantly to change original equipment is not lost former loop back roll yet can not cause the generation of secondary problem yet, can prevent to cause because of various factors with the problem of steel sideslip behind the finishing mill inner-threading on certain degree and can play dynamic correction effect continuously and fill up domestic this blank of technical field on the one hand.The utility model frame for movement is simple, reasonable, and reliable working operation has realized the function that loop back roll laterally moves along axis direction; Played the dynamically effect of correction continuously; Prevent the problem of band steel sideslip behind the finishing mill inner-threading, improved product quality, reduced the generation of steel scrap accident.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below,
Fig. 1 is the working face plan structure sketch map of the utility model;
Fig. 2 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of kink understructure that prevents strip running deviation; Like Fig. 1, shown in Figure 2; Comprise and be installed in two finishing mills 2, the loop back roll between 93; On two finishing mills 2, beam base 8 its sides between 9, T shape guide groove is being set; Shape of cross section is that the crossbeam 6 of T shape matches with the T shape guide groove of beam base 8, affixed oil cylinder 7 on the bearing that beam base 8 left ends are provided with, and oil cylinder 7 piston rod ends are connected with the left end of crossbeam 6; The left and right side kink arm 5,10 of articulated two symmetries on the outer face of the T shape crossbeam 6 that stretches out beam base 8T shape guide groove two ends; Affixed respectively left and right bearing block 4,11 is installed with loop back roll 3 through left and right bearing block 4,11 in the outer end of left and right side kink arm 5,10, is installing two hoist cylinder bases 12 of symmetry respectively at the two ends, bottom of crossbeam 6; Two hoist cylinders 13 of the articulated symmetry of difference on two hoist cylinder bases 12 of symmetry, two hoist cylinder 13 piston rod ends of symmetry are hinged on respectively on the corresponding kink arm 5,10.The axis of oil cylinder 7 is consistent with the length direction of crossbeam 6.During work;, band steel 1 sets up under the effect of tension force after wearing the band completion; The roll surface of loop back roll 3 has produced function of friction with the surface of band steel 1; When the band steel because of the effect that receives extraneous factor when generation is along to the left or to the right active force of loop back roll center line down; Oil cylinder 7 moves and has realized that crossbeam 6 drives the function that loop back rolls 3 in axial direction move through promoting crossbeam 6, thereby has realized 3 pairs of correction effects of being with the sideslip of steel 1 of loop back roll because of the lower end of kink hoist cylinder 13 is connected oscilaltion that has just realized loop back roll 3 on the crossbeam 6 and the combination holding function that laterally moves simultaneously.
