The invention can effectively improve the shape and quality of strip steel, can prolong the service life of the bending cylinder block, and is beneficial to the improvement of cold-rolling mill yield. The bending cylinder block of the invention is applicable to six-roller cold rolling mills, four-roller cold rolling mills and temper mills.
Description
Technical field
The present invention relates to a kind of six-roll cold mill working roll, particularly relate to a kind of bending cylinder block of six-roll cold mill working roll.
Background technology
Bending cylinder block is one of vitals of cold-rolling mill.In cold rolling production, bending cylinder block presses working roll and backing roll, prevents that working roll and backing roll from skidding when unloaded and startup; If the pressure of bending cylinder block is increased, can realize the effect of positive and negative roller, all be vital for plate shape and the quality of controlling steel plate.
Following steel rolling production is towards high speed, heavy duty, high strength, high rigidity, high accuracy, serialization and automation direction development, and this also has higher requirement to bending cylinder block.Therefore, the bending cylinder block of designing high quality and low cost is extremely important.
Existing bending cylinder block is integrative-structure mostly, bending cylinder block two roller hydraulic cylinders are respectively arranged up and down, the head of roller hydraulic cylinder is equipped with guide pad, guide pad inserts in the groove of working roll bearing block.Play the roller effect by roller hydraulic cylinder flexible during work.
The deficiency that existing bending cylinder block structure exists is:
1, upper and lower two roller hydraulic cylinders are difficult to be synchronized with the movement, and cause the working roll bearing block unbalance stress, influence belt plate shape and quality.
2, the cylinder bar of roller hydraulic cylinder is vulnerable to impact when milling train is worked; The working roll slide plate is installed on the bending cylinder block, impacts the cylinder body of bending cylinder block during milling train work, and these all can influence the service life of bending cylinder block and the plate shape and the quality of band steel.
The cylinder bar of roller hydraulic cylinder can rotate at random when 3, working, and delays the roll changing time of cold-rolling mill, influences the output of cold-rolling mill.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of bending cylinder block, can effectively improve the plate shape and the surface quality of steel plate, increases the service life the raising of favourable cold-rolling mill output.
For solving the problems of the technologies described above, bending cylinder block of the present invention comprises: go up bending cylinder block, following bending cylinder block and roller hydraulic cylinder; Last bending cylinder block is connected by the roller hydraulic cylinder with following bending cylinder block, and along with roller hydraulic cylinder flexible done relative motion; Last bending cylinder block and following bending cylinder block can move up and down on the bearing support cylinder cylinder body; Also comprise two guide posts, be arranged between bending cylinder block and the following bending cylinder block, be individually fixed on the upper and lower bending cylinder block of bending cylinder block.
Each fixes a thicker guide post on the upper and lower bending cylinder block among the present invention, and to the impact of upper and lower bending cylinder block, guide post is difficult for deforming in the time of well bearing mill milling, thereby has improved the plate shape and the surface quality of band steel.
In addition, after adopting bending cylinder block of the present invention, the roller hydraulic cylinder that connects between the upper and lower bending cylinder block can adopt articulated manner to be connected with last bending cylinder block, in the time of eliminating mill milling effectively to the impact of roller hydraulic cylinder, improve the service life of roller hydraulic cylinder, reduced the maintenance cost of equipment.
Bending cylinder block efficient work of the present invention, is accurately safeguarded simple and easyly, and cost is reasonable.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is the bending cylinder block structure chart;
Fig. 2 is the enlarged drawing of bending cylinder block.
Description of reference numerals among the figure:
The 1st, last bending cylinder block, the 2nd, following bending cylinder block, the 3rd, crossbeam,
The 4th, the roller hydraulic cylinder, the 5th, guide post, the 6th, the hinged securement pin,
The 7th, clamp.
The specific embodiment
Shown in Fig. 1,2, bending cylinder block of the present invention comprises: go up bending cylinder block 1, following bending cylinder block 2 and roller hydraulic cylinder 4.On the bending cylinder block 2, its upper end was equipped with anchor bearing, is connected with last bending cylinder block 1 by hinged securement pin 6 under described roller hydraulic cylinder 4 was fixed in; 2 of last bending cylinder block 1 and following bending cylinder blocks are done relative motion by roller hydraulic cylinder 4 flexible.
Last bending cylinder block 1 and following bending cylinder block 2 are stuck on the bearing support cylinder cylinder body by dismountable clamp 7 respectively, and bending cylinder block 1 and following bending cylinder block 2 can only move up and down along described bearing support cylinder cylinder body in the assurance.
Per two of described bending cylinder block is a cover, establishes two covers altogether, lays respectively at the fore side and the driving side of cold rolling mill work roller; The corresponding setting about two bending cylinder blocks in every cover; The last bending cylinder block 1 that is positioned at fore side and driving side both sides is connected by crossbeam 3, and the following bending cylinder block 2 that is positioned at fore side and driving side both sides is connected by crossbeam; Adjusting by hydraulic system can realize that 1,2 motions of bending cylinder block up and down of fore side and driving side are consistent.
During positive roller, the lever withdrawal of roller hydraulic cylinder 4, last bending cylinder block 1 descends bending cylinder block 2 to move downward relatively, and the drive double-working is drawn close, and plays positive roller effect under the supporting of backing roll.
When bearing roller, the lever of roller hydraulic cylinder 4 stretches out, and last bending cylinder block 1 descends bending cylinder block 2 to move upward relatively, drives double-working separately, plays negative roller effect under the supporting of backing roll.
Crossbeam 3 between fore side and the driving side bending cylinder block plays the effect of supporting track when work roll changing.
What installed the upper end of roller hydraulic cylinder 4 is anchor bearing, hinged securement pin 6 is inserted the anchor bearing of going up bending cylinder block 1 and roller hydraulic cylinder 4 upper ends, roller hydraulic cylinder 4 is connected with last bending cylinder block 1, can when working, effectively eliminate bending cylinder block the stress between roller hydraulic cylinder 4 and the last bending cylinder block 1, improve the stressing conditions of roller hydraulic cylinder 4 greatly, increase the service life.
Bending cylinder block of the present invention also can be used for 4-roller cold rolling mill and planisher.
More than by the specific embodiment the present invention is had been described in detail, but these are not to be construed as limiting the invention.Under the situation that does not break away from the principle of the invention, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection scope of the present invention.
