Description
Technical field
The utility model relates to a kind of device preventing strip running deviation from affecting flying shear shearing, belongs to continuous hot-rolling mill manufacture field.
Background technology
Hot continuous rolling production line flying shear major function is by the strip steel head of roughing mill rolling, the irregular Partial Shear of afterbody, ensures that band steel is at the good profile of mm finishing mill unit and normal threading.In process of production, due to plate shape difference or finishing mill strip running deviation in the operation of rolling of upper operation supplied materials, be with steel to exceed cutting edge when causing flying shear to be sheared and shear scope, cause shearing unclean.Occur this type of fault, rolling line can be caused on the one hand to produce steel scrap, the opposing party wears steel toe and causes the serious accident of other equipment (as mill's main drive shaft is damaged) to cause long disorderly closedown with being with steel to enter milling train.
Summary of the invention
The utility model provides a kind of device preventing strip running deviation from affecting flying shear shearing, can when being with steel to occur sideslip, and pilot tape steel runs within the scope of the shearing of flying shear blade.In flying shear shear history, avoid occurring that the phenomenon of adhesion, magnetic tape trailer sheared by flying shear, thus the pernicious fault of milling equipment reducing rolling line steel scrap and cause therefrom.
The technical solution adopted in the utility model is: a kind of device preventing strip running deviation from affecting flying shear shearing, it is characterized in that: comprise guide plate support, two guide plate supports are separately positioned on cutting edge working face both sides, and guide plate support welding is on the memorial archway of flying shearing machine outlet both sides; Guide plate bracket cross section is trapezium structure, and centre is hollow, and the swash plate on guide plate support is guided plate, is provided with wearing plate, contacts with the strip outside the vertical short slab of guided plate and below thereof, and the angle of guided plate and vertical direction is 39 °.
In such scheme, the mounting distance of described two guide plate supports is 1510mm, and guide plate support is of a size of: long 500mm, wide 305mm, thick 300mm, and the width of guided plate is 160mm.
The utility model according to the actual size of the state around scene and flying shear body, shaping-orientation board mount.The part that guide plate rack surface contacts with the strip, adopts the good 16Mn of wearability to make, and simultaneously for avoiding the device top steel increased newly to cause rolling line steel scrap, design gradient in guide plate support front portion is the guided plate (i.e. described swash plate) of 39 °.After guide plate supporting frame prefabrication, be fixed on the memorial archway surface of flying shear outlet both sides.After installation, the distance of two guide plate supports is 1510mm, 40mm less of the width (1550mm) of cutting edge, one-sided little 20mm.Meet the requirement (the maximum rolling width 1410mm of product) of maximum rolling width on the one hand; Ensure on the other hand, in band steel running, not exceed the width range of cutting edge.
What the utility model provided prevents strip running deviation from affecting the device of flying shear shearing, the beneficial effect brought:
(1) when being with steel to occur sideslip, pilot tape steel runs within the scope of the shearing of flying shear blade, avoids occurring that strip running deviation causes flying shear to shear unclean phenomenon;
(2) avoid occurring that the phenomenon of adhesion, magnetic tape trailer sheared by flying shear in flying shear shear history, thus the pernicious fault of milling equipment reducing rolling line steel scrap and cause therefrom;
(3) shear precision that flying shear runs is improved.
Below in conjunction with drawings and Examples, the utility model is described further.

Detailed description of the invention
Embodiment:
As shown in Figure 1, a kind of device preventing strip running deviation from affecting flying shear shearing, it is characterized in that: comprise guide plate support 3, two guide plate supports 3 and be separately positioned on cutting edge 2 working face both sides, guide plate support 3 is welded on the flying shearing machine memorial archway 1 of flying shearing machine outlet both sides; Guide plate support 3 cross section is trapezium structure, and centre is hollow, and the swash plate on guide plate support 3 is guided plate, is provided with wearing plate, contacts with the strip outside the vertical short slab of guided plate and below thereof, and the angle of face, swash plate place and vertical direction is 39 °.
The mounting distance of described two guide plate supports is 1510mm, and guide plate support is of a size of: long 500mm, wide 305mm, thick 300mm, and the width of guided plate is 160mm.
Concrete preparation method is:
According to the actual size of the state around scene and flying shear body, shaping-orientation board mount.The part that guide plate rack surface contacts with the strip, adopts the good 16Mn of wearability to make, and simultaneously for avoiding the device top steel increased newly to cause rolling line steel scrap, design gradient in guide plate support front portion is the guided plate of 39 °.After guide plate supporting frame prefabrication, be fixed on the memorial archway surface of flying shearing machine outlet both sides.After installation, the distance of two guide plate supports is 1510mm, 40mm less of the width (1550mm) of cutting edge, one-sided little 20mm.Meet the requirement (the maximum rolling width 1410mm of product) of maximum rolling width on the one hand; Ensure on the other hand, in band steel running, not exceed the width range of cutting edge.
Guide plate support efficiently solves because of strip running deviation after dropping into and trying out, and causes flying shear to shear unclean phenomenon, avoids the rolling line steel scrap and fault time that cause thus.
Frequently similar phenomenon is there is during in October, 2014 ~ December.Add up to cause steel scrap 60 tons, rolling line fault 150 minutes, amount to loss: 1, spoiled time 150 minutes × 0.03 ten thousand yuan/minute=0.45 ten thousand yuan; 2, steel finished product per ton and steel scrap price difference 0.3 ten thousand yuan, namely steel scrap loses 60 tons × 0.3 ten thousand yuan/ton=180,000 yuan.Trial edition utility model realizes economic benefit and amounts to 18.45 ten thousand yuan.
