Abstract
The utility model relates to a short stress universal rolling mill, and in particular to a short stress universal rolling mill with a deviated vertical roll, which comprises a vertical roll, horizontal rolls, a bearing seat, a middle framework, a connection pipe and a depress screw rod, wherein the quantity of the horizontal rolls is two, and the horizontal rolls are vertically installed on the rolling mill through the bearing seat; the vertical roll is installed between the upper and the lower horizontal rolls, two ends of the vertical roll are fixed on the milling roll respectively through the middle framework of the rolling mill, the middle framework on two ends of the vertical roll is connected with each other through the connection pipe, the depress screw rod acts on the bearing seat of the upper and the lower horizontal rolls so as to close the upper and the lower horizontal rolls, and is characterized in that the circular center vertical line of an end surface circle of the vertical roll is deviated from the circular center vertical line of the end surface circle of the horizontal roll, and the deviation distance is e. The short stress universal rolling mill is modified on the basis of the original rolling mill, so the re-investment on the rolling mill is small, and the quality of the product and the service life of the rolling mill can be effectively improved.
Description
Technical field
The utility model relates to a kind of short stress universal mill, especially a kind of short stress universal mill of edger roll skew.
Background technology
H shaped steel is good because of its mechanical property, modulus of section is big, in light weight, the saving metal, and welding, the advantage that the riveting work amount is little, it is big to be usually used in the requirement bearing capacity, the heavy construction of cross section good stability, as factory building, skyscraper, and be used for bridge, boats and ships, hoisting and conveying machinery and equipment, basis, support, foundation pile.The short stress universal mill of domestic widely-used Italian Danieli Off Mecc is produced H shaped steel at present, this milling train becomes needed H shaped steel with horizontal roller with strip-rolling by edger roll, horizontal roller is two, be installed in the milling train upper and lower position by bearing block respectively, edger roll is arranged between two horizontal roller, the edger roll two ends are fixed on the milling train by the central frame of milling train, connect by tube connector between two central frames, milling train gives bearing block pressure by depressing leading screw, with upper and lower horizontal roller closure, it depresses the leading screw diameter is 165mm.This equipment has certain superiority in production practices, therefore be widely used, but also there are some problems, at first be that this equipment is in the operation of rolling, because the central frame tube connector at edger roll two ends is a hollow pipe, therefore reduce mill stiffness, caused in the operation of rolling edger roll to beat greatly, thereby reduced the stability of shaped steel shank rolling deformation; Secondly, edger roll adopts the plane bolt to be connected with central frame, makes that the edger roll location is inaccurate, and it is lower that roll gap is adjusted precision, influenced dimensional accuracy of products, causes product quality to reduce; The 3rd, its axle center was on same straight line when the edger roll of this milling train and horizontal roller were installed, therefore, at first be subjected to the roll-force from edger roll after shaped steel enters rolling interval, the shaped steel shank is stress and deformation at first, web contacts with horizontal roller more then, in edger roll and horizontal roller, form needed product under the effect,, make that the shaped steel distortion is unstable because web and shank are not to be subjected to roll-force simultaneously, the inner defective that produces, product quality is affected.
Summary of the invention
To be solved in the utility model is exactly that present short stress rolling mill roll is beated greatly, the rolling deformation problem of unstable, and a kind of short stress universal mill that can reduce the edger roll skew that roll is beated, rolling deformation is stable is provided.
The short stress universal mill of edger roll skew of the present utility model comprises edger roll, horizontal roller, bearing block, central frame, tube connector and depresses leading screw that horizontal roller is two, is vertically mounted on the milling train by bearing block; Edger roll is installed between the upper and lower horizontal roller, the edger roll two ends are fixed on the milling train by the central frame of milling train respectively, connect by tube connector between the central frame at edger roll two ends, depress on the bearing block that leading screw acts on upper and lower horizontal roller, with upper and lower horizontal roller closure, the center of circle vertical line that it is characterized in that the center of circle vertical line offset level roller end face circle of described edger roll end face circle is installed, and its offset distance is e.
Described is 10mm～15mm apart from e.
Described tube connector is a solid hopkinson bar, improves the fastness of milling train, increases mill stiffness.
Described edger roll uses bolt to be connected with central frame, improves the positioning accuracy of edger roll.
The described leading screw diameter of depressing is 180mm.
Short stress universal mill of the present utility model, the edger roll position is offset, make the web of shaped steel when rolling and shank can be subjected to edger roll simultaneously and horizontal roller is rolling, reduced web because of being out of shape the internal flaw that shakiness causes, use solid hopkinson bar simultaneously instead and depress the diameter of leading screw as tube connector, increase, improve the bonding strength of milling train, increased the rigidity of milling train, effectively reduced beating of roll when rolling, for the shape defect that reduces product positive role is arranged, can also reduce the wearing and tearing of milling train because of beating and producing; Edger roll adopts bolt to connect, and can improve the adjustment precision of roll gap, strengthens the control to the product size precision.
Short stress universal mill of the present utility model is transformed on the basis of original milling train, and is little to the input again of milling train, can also effectively improve the quality of product and the service life of milling train.

The specific embodiment
Embodiment 1: a kind of short stress universal mill of edger roll skew comprises edger roll 1, horizontal roller 2, bearing block, central frame, tube connector and depresses leading screw that horizontal roller 2 is two, is vertically mounted on the milling train by bearing block respectively; Edger roll 1 is installed between the upper and lower horizontal roller 2, and edger roll 1 two ends are fixed on the milling train by central frame respectively, connects by solid hopkinson bar between the central frame at upright rod 1 two ends; Depress on the bearing block that leading screw acts on upper and lower horizontal roller 2, upper and lower horizontal roller 2 closures; The center of circle vertical line horizontal range of the center of circle vertical line of edger roll 1 end face circle and horizontal roller 2 end faces circle is e, adjust according to the contact arc length difference of rolled section steel 3 apart from e, when contact arc length difference is 15mm, its offset distance e is 15mm, guaranteed that shaped steel 3 is subjected to the rolling of edger roll 1 and horizontal roller 2 simultaneously this moment, increase the stability of shaped steel 3 rolling deformations, reduced the shaped steel 3 inner defectives that produce, guaranteed its quality.The tube connector that connects between the central frame is selected solid hopkinson bar for use, improve the fastness of milling train, increase mill stiffness, it is 180mm that the diameter of depressing leading screw that acts on bearing block is increased by original 165mm, the stable of leading screw, beating when reducing mill milling are depressed in increasing.Edger roll 1 is used bolt instead and is connected with central frame, improves the positioning accuracy of edger roll 1, strengthens the adjusting range of roll gap, better the geomery of product is controlled.The utility model is transformed on the basis of original milling train, and the improvement expenses with lower just can improve the quality of products effectively, just operates left-hand seat fast nor need to be familiar with again milling train.
