The specific embodiment

Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.

A kind of outer installing rack of cold-rolling mill roller case that has rolling line adjusting device; Shown in Fig. 1～4; The innovation of the utility model is: comprise its interior frame 1 that the frame-type of top roll case 10 and lower roll case 12 is installed; Installation one is used to carry the base 7 of lower roll case bottom this frame, and the jack-up hydraulic cylinder 6 that is used for jack-up lower roll case is installed in the base, and frame upper end installation one is used to compress the last rolling line adjusting device of top roll case; Symmetry on the entablature 3 of frame two sides install two groups be used to regulate the top roll case on convexity adjusting device 2, symmetry is installed two groups of following convexity adjusting devices 5 that are used to regulate the lower roll case on the sill 16 of frame two sides.

In the present embodiment; Last rolling line adjusting device is shown in 5～10: comprise panel 20, oblique crushing block 8, intermediate mass 9, adjustment hydraulic cylinder 4; The adjustment hydraulic cylinder is installed in frame driving side upper end through suspension bracket 27; Its piston rod end connects the rear end of oblique crushing block, and the upper end of this oblique crushing block is crimped on the bottom surface of the frame upper end panel of adorning through connector 21, and the inclined-plane, lower end of this oblique crushing block 4 of intermediate mass through two parallel interval settings respectively compresses on the top roll case contiguously.

Tiltedly the skewback that a bottom surface descends from front end is to the back-end gradually respectively made in the front and back of crushing block, and the inclined-plane (seeing the upper end of Fig. 9 hatching fill area) that matches with the skewback bottom surface is made in the intermediate mass upper end, and two skewbacks are all identical with the syndeton of intermediate mass; Skewback both sides are all identical with the syndeton of intermediate mass both sides; Skewback one side with front end is that example describes below, and sliding way 25 and glide path 26 are made in the two sides of skewback, the tenon 31 of setting-in one contiguous block 22 in the sliding way; The upper end and the panel of this contiguous block are fixed; One positioning key 23 is installed on this contiguous block, and the lower end of this positioning key vertically is inlaid in the made groove in intermediate mass side 24, and promptly positioning key makes the play about intermediate mass can not occur; Inboard, intermediate mass end is shaped on a square groove 28; Through the fixing inverted L shaped slide block 30 of screw, in the glide path that the upper end of this L shaped slide block protruding 32 is inlaid on the skewback, promptly L shaped slide block makes intermediate mass play up and down can not occur in this square groove.

When the adjustment hydraulic cylinder advanced oblique crushing block to advance, owing to advance intermediate mass is pushed downwards in the skewback bottom surface, intermediate mass moved downward along positioning key; L shaped slide block slides along glide path simultaneously, intermediate mass is descended top roll case upper end is formed extruding force, and downward convexity 33 is all made at these two intermediate mass two ends; Making two intermediate mass form with top roll case upper end at 4 contacts; Even to the pressure of top roll case like this, avoided the roller case to be squeezed and to be out of shape the roll-force that causes inhomogeneous, and the effect of drawing in has been played by the system of the roller in the pair roller case; In order to reduce weight, on intermediate mass, also be shaped on lightening hole 29.

The convexity adjusting device of being adorned on the frame one side crossbeam is 14 (sums of upper and lower crossbeam); The both sides crossbeam is installed 28 altogether; The structure of a plurality of convexity adjusting devices of installing on the entablature of frame two sides is all identical; Be the example explanation with a convexity adjusting device below: comprise convexity regulator solution cylinder pressure 13, pull bar 14, tapered wedges 15 and middle crushing block 18; A plurality of convexity regulator solution cylinder pressures are installed in the entablature upper end at interval; Each convexity is regulated hydraulic cylinder piston rod and is driven the tapered wedges of setting-in in the entablature through the pull bar that installs in the entablature, saddle 19 crimping of being adorned on the bearing of being adorned on the end face of each tapered wedges 17 and the end face crimping mutually of middle crushing block, the other end of middle crushing block and the interior backing roll 11 of top roll case mutually.

The structure of a plurality of convexity adjusting devices of installing on the sill of frame two sides is all identical; Be the example explanation with a convexity adjusting device below: comprise convexity regulator solution cylinder pressure, pull bar, tapered wedges and middle crushing block; A plurality of convexity regulator solution cylinder pressures are installed in sill 16 bottom surfaces at interval; Each convexity is regulated hydraulic cylinder piston rod drives setting-in in the sill through the pull bar that installs in the sill tapered wedges; The saddle crimping of being adorned on the backing roll in the bearing of being adorned on one end face of each tapered wedges and the end face crimping mutually of middle crushing block, the other end of middle crushing block and lower roll case mutually.
