Abstract
The invention provides a vertical roll stressing structure of a universal mill. The vertical roll stressing structure comprises left and right brackets, a lateral compression cross beam, a window cross beam and a vertical roll, wherein the vertical roll is connected with the lateral compression cross beam; the lateral compression cross beam is connected with a bracket through a first stud; and the left and right brackets are connected with the window cross beam arranged between the left and right brackets through second studs. The vertical roll stressing structure has the beneficial effects that: by adopting the technical scheme, window deformation can be reduced, the rigidity of the vertical roll can be enhanced, waist height of H steel can also be accurately controlled, and constant strength design concept is met.
Description
Technical field
The present invention relates to universal mill, especially relate to universal mill edger roll force structure.
Background technology
Because H shaped steel has excellent mechanical property, on industrial building and civil buildings, obtained to use widely.H shaped steel has parallel shank, is convenient to machining and installation, not only elegant in appearance but also labor and material saving.H shaped steel is used in the architectural construction weight that can make and alleviates 30%, is used in ability weight reduction 15% on the bridge, all uses H shaped steel to replace original gradient I-steel in many countries.Be accompanied by H shaped steel in each item extensive applications; The H shape rolling mill also develop gradually perfect; Develop into the board-like universal mill of present connection, short-stress path universal mill, be with prestressed UC universal mill by original memorial archway formula universal mill; These milling trains universal mill more in the past has higher rigidity, better, the more economical light and thin type H shaped steel of the rolling mechanical property of ability; Also these universal mills are come by use widely in each country Just because of this, have replaced old-fashioned memorial archway formula universal mill gradually.
The short-stress path universal mill is present most popular a kind of high rigidity universal mill; Edger roll is the important composition parts of universal mill, and it is arranged symmetrically in the milling train both sides, and its suffered roll-force is about the half the of horizontal roller roll-force; The strain that the stressed back of the stress of edger roll and associated part thereof produces is extremely important equally to the influence of product precision; On traditional universal mill (Fig. 1), edger roll 7 is when rolling, and roll-force at first passes to the side pressure nut through the side pressure screw; The side pressure nut passes to side pressure crossbeam 2 with roll-force again, and side pressure crossbeam 2 couples together itself and support 1, window crossbeam 5 through bolt (being hydraulic bolt 8 among this figure).As can be seen from Figure 1, edger roll 7 suffered roll-forces finally act on the window crossbeam 5, because edger roll 7 symmetric arrangement; The 5 stressed back distortion of window crossbeam; The window distortion when receiving roll-force of this structure edger roll is bigger, causes the rigidity of edger roll to reduce, and the waist height of H shaped steel can not get accurate control.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of and can reduce window distortion, enhancing edger roll rigidity, can accurately control the high universal mill edger roll force structure of H shaped steel waist again.
Technical scheme of the present invention is: universal mill edger roll force structure; Comprise left and right sides support, side pressure crossbeam, window crossbeam and edger roll; Said edger roll links to each other with the side pressure crossbeam; Said side pressure crossbeam links to each other with support through first double-screw bolt, said left and right sides support pass through second double-screw bolt with wherein between the window crossbeam link to each other.
Said first double-screw bolt is identical with the diameter of second double-screw bolt.
Advantage and good effect that the present invention has are: adopt technique scheme, can reduce the window distortion, strengthen edger roll rigidity, it is high accurately to control H shaped steel waist again, satisfies the equal strength design concept.
Description of drawings
Fig. 1 is the structural representation of prior art universal mill;
Fig. 2 is a structural representation of the present invention.
Among the figure:
1, support 2, side pressure crossbeam 3, first double-screw bolt
4, locking nut 5, window crossbeam 6, second double-screw bolt
7, edger roll 8, hydraulic bolt
The specific embodiment
As shown in Figure 2; Universal mill edger roll force structure of the present invention; Comprise left and right sides support 1, side pressure crossbeam 2, window crossbeam 5 and edger roll 7, edger roll 7 links to each other with side pressure crossbeam 2 through side pressure screw, side pressure nut, and side pressure crossbeam 2 links to each other with support 1 through first double-screw bolt 3; Left and right sides support 1 through second double-screw bolt 6 with wherein between window crossbeam 5 link to each other, first double-screw bolt 3 and second double-screw bolt 6 pass through locking nut 4 respectively and lock.
Edger roll of the present invention 7 is stressed as shown in Figure 2, and the roll-force of edger roll 7 at first acts on the side pressure crossbeam 2 through side pressure screw, side pressure nut, and side pressure crossbeam 2 links to each other with support 1 through first double-screw bolt 3; Like this, edger roll 7 roll-forces are delivered on the support 1, and are last; Through second double-screw bolt 6 with left and right sides support 1 and wherein window crossbeam 5 couple together; Because edger roll 7 left-right symmetric, the roll-force of edger roll 7 is all born by second double-screw bolt 6 at last, and this structure changes into the stretcher strain of window the stretcher strain of double-screw bolt; Its distortion obviously reduces; Bear identical roll-force owing to first double-screw bolt 3 with second double-screw bolt 6 simultaneously, and its diameter is identical, so this structure satisfies the equal strength design concept.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
Claims (2)
1. universal mill edger roll force structure; Comprise left and right sides support (1), side pressure crossbeam (2), window crossbeam (5) and edger roll (7); Said edger roll (7) links to each other with side pressure crossbeam (2); It is characterized in that: said side pressure crossbeam (2) links to each other with support (1) through first double-screw bolt (3), said left and right sides support (1) pass through second double-screw bolt (6) with wherein between window crossbeam (5) link to each other.
