Abstract

The utility model discloses a modular rolling -mill housing is optimized structure, the box -like rolling -mill housing of this species group is divided and is formed by entablature, bottom end rail, left stand, the right stand four bibliographic categories, and wherein the perpendicular buckle of upper and lower crossbeam boss is between coexistence post recess. The utility model discloses a change upper and lower crossbeam boss angle and reach the left and right stand recess angle of complex with it, make crossbeam and stand faying face become the inclined plane. At the rolling process, power is decomposed on the inclined plane, makes stand institute flexural square reduce, and can reduce the frame window in the rolling process is out of shape, reduces to roll the roll chock extrusion extent of damage, reduces crossbeam and stand faying face fracture clearance simultaneously, improves frame stability.

Description

Cimbination mill frame is optimized structure

Technical field

The utility model belongs to steel rolling equipment field, discloses a kind of cimbination mill rack construction.

Background technology

Along with the development of national economy, to the size of sheet material and quality requirement more and more higher, milling train volume is also day by day huge, adopts traditional integral casting difficulty of processing large, transport, installs difficulty; The appearance of combined frame efficiently solves an above difficult problem, becomes the development trend of wide and heavy plate mill frame; Existing cimbination mill frame window deflection in the operation of rolling is large, and and crossbeam and column faying face ftracture, greatly, roll chock is easily squeezed and damages in gap, and frame poor stability.

Summary of the invention

To there is window deflection to existing composite machine shelf structure in the utility model large in the operation of rolling, and crossbeam and column contact surface ftracture the large deficiency in gap, provide cimbination mill frame and optimize structure, effectively solve the problem.

The utility model comprises: cimbination mill frame is optimized structure, and comprises entablature 1, sill 2, left column 3, right column 4, upper and lower crossbeam boss is vertically buckled in left and right stake pocket, boss and groove fit place angle variable within the scope of 70 to 90 degree, namely mating surface is inclined-plane.

As preferably, A111, A112, A121, A122 are variable within the scope of 70 to 90 degree at entablature 1 boss angle, and angle A111 equals angle A121, and angle A112 equals angle A122.

As preferably, A211, A212, A221, A222 are variable within the scope of 70 to 90 degree at sill 2 boss angle, and angle A211 equals angle A221, and angle A212 equals angle A222.

As preferably, left column 3 fovea superior groove angle A311, A312 are respectively with entablature boss angle A111, A112 correspondent equal coordinated with it, and recessed groove angle A321, A322 are respectively with sill boss angle A211, A212 correspondent equal coordinated with it.

As preferably, right column 4 fovea superior groove angle A411, A412 are respectively with entablature boss angle A121, A122 correspondent equal coordinated with it, and recessed groove angle A421, A422 are respectively with sill boss angle A221, A222 correspondent equal coordinated with it.

The utility model is owing to adopting above technical scheme, technique effect: by changing angle, make crossbeam become inclined-plane with column faying face, can reduce framework window distortion in the operation of rolling, thus reduces roll chock extrusion damage degree; Frame can be reduced in the cracking gap of operation of rolling middle cross beam with column simultaneously, thus the stability of raising frame.

In figure: 1 is entablature, 11 is the left boss of entablature, and 12 is the right boss of entablature, and A111, A112, A121, A122 are respectively boss angle; Fig. 2 is sill, and 21 is the left boss of sill, and 22 is the right boss of sill, and A211, A212, A221, A222 are respectively boss angle; Fig. 3 is left column, and 31 is upper groove, and 32 is low groove, and A311, A312, A321, A3221 are FLUTE ANGLE; Fig. 4 is right column, and 41 is upper groove, and 42 is low groove, and A411, A412, A421, A4221 are FLUTE ANGLE.

Detailed description of the invention

Below in conjunction with Fig. 1 to Fig. 5, an embodiment of the present utility model is further described:

Cimbination mill rack construction, upper and lower crossbeam boss is vertically buckled between two stake pockets; Drawn by Optimization analyses, described entablature 1 boss A111, A121 get 74 degree of angles, and A112, A122 get an angle of 90 degrees; Sill 2 boss A211, A221 get 79 degree of angles, and A212, A222 get 87 degree of angles; Left column 3 upper groove A311 gets 74 degree of angles, and A312 gets an angle of 90 degrees, and low groove A321 gets 79 degree of angles, and A322 gets 87 degree of angles; Right column 4 upper groove A411 gets 74 degree of angles, and A412 gets an angle of 90 degrees, and low groove A421 gets 79 degree of angles, and A422 gets 87 degree of angles.The change of angle makes the faying face of crossbeam and column become inclined-plane, when bearing roll-force, power is decomposed on inclined-plane, the moment of flexure that column bears reduces, so framework window " necking down " amount reduces, and crossbeam and column mating surface ftracture, gap reduces, this reduces the roll chock extruding extent of damage caused because of window distortion, improve the stability of frame simultaneously.
