Description
Technical field
The utility model relates to rolling mill lower roll adjusting device, especially relates to a kind of vertical wedge-type manual adjusting device of lower roll that is used for rolling mill.
Background technology
In general, the rolling of bar and shaped steel is to realize by the hole shape that designs on the roll, and roll gap is one of parameter of hole shape design, owing to wearing and tearing and other reason of roll, roll gap will often be adjusted when producing, and in down roll gap mainly realize by adjusting the lower roll position.Present such lower roll adjusting device mostly is electricity greatly and drives or hydraulic-driven, and not only cost is higher, and energy consumption is bigger, is unfavorable for environmental protection requirement.
The utility model content
The purpose of this utility model is to provide a kind of lower roll that is used for rolling mill simple in structure and convenient manual operation vertical wedge-type manual adjusting device.
For achieving the above object, the utility model can be taked following technical proposals:
The vertical wedge-type manual adjusting device of lower roll that is used for rolling mill described in the utility model, comprise the roll elevating bracket that is horizontally set on the roll chock below, level is coaxially arranged with two lifting units between described roll elevating bracket and rolling mill frame, and the opposite end of described two lifting units is connected with the lifting axis by shaft coupling respectively; Described lifting axis is connected with the roll elevating bracket by bearing support block, in described two lifting unit outer setting dirt-proof boot is arranged; Described two lifting units are horizontally disposed screw mandrel, the branch body structure that described screw mandrel is structure as a whole or connects by shaft coupling, and described screw mandrel outer end is provided with the adjustment handwheel, and inner and described shaft coupling is connected; Be set with the wedge shape screw on described screw mandrel, described wedge shape screw top and described roll elevating bracket are slidingly connected; Described rolling mill frame is provided with base, and described base is provided with the stationary wedge piece, and the upper surface of described stationary wedge piece and wedge shape screw lower surface are slidingly connected, and the gradient phase coadaptation of contact-making surface.
Be provided with abrasion-proof backing block below described roll elevating bracket, described abrasion-proof backing block and described wedge shape screw are slidingly connected.
Be provided with the adjustment bolt in described stationary wedge piece one side, be provided with the adjustment backing plate in stationary wedge piece bottom.
The screw mandrel at described two lifting unit two ends is connected with the roll elevating bracket by bearing block respectively.
Be provided with the adjustment spring in described bearing support block, bearing block and roll elevating bracket junction.
Advantage of the present utility model is not only simple in structure, and is easy to manufacture; And the operator only needs with the hands to regulate lifting simultaneously about the roll elevating bracket easily, need not electricity consumption driving or hydraulic-driven, has saved the energy, and its cost is reduced.During use, the operator rotates the adjustment handwheel at two ends, make the screw mandrel rotation at two ends, driving the wedge shape screw moves in or out, owing to the gradient of wedge shape screw with the relative sliding surface of stationary wedge piece, make lifting simultaneously about the roll elevating bracket to drive roll chock, realize the roll gap adjustment together with the roll lifting.Be provided with abrasion-proof backing block below the roll elevating bracket, described abrasion-proof backing block and wedge shape screw are slidingly connected, and have improved anti-wear performance greatly, have improved the service life of roll elevating bracket.Be provided with the adjustment bolt in described stationary wedge piece one side, be provided with the adjustment backing plate,, can adjust the levelness of roll elevating bracket, to guarantee roll silk seam evenly by two adjustment bolts about adjusting in stationary wedge piece bottom; Can adjust the oscilaltion amplitude of roll by the thickness of adjusting backing plate.The screw mandrel at described two lifting unit two ends is connected with the roll elevating bracket by bearing block respectively, has strengthened the support strength between screw mandrel and the roll elevating bracket.Because the distortion in machining accuracy and the use, feasible difficult assurance of concentricity that is used for each fulcrum of screw rod and the left and right nut of bearing support block, bearing block and roll elevating bracket junction, adjust the position that spring then can be finely tuned each fulcrum by being provided with in roll elevating bracket junction, thereby guarantee the concentricity of fulcrum, more smooth and easy during manual operation.
