The working roll traversing device is characterized by comprising a fixed block, traversing hydraulic cylinders, a movable block, and a lock hydraulic cylinder; the fixed block is connected with the traversing hydraulic cylinders; the traversing hydraulic cylinders are hinged with the movable block; the axial central lines of the traversing hydraulic cylinders and the movable block are on the same straight line; the integrated lock hydraulic cylinder is arranged in the movable block; and a displacement sensor is arranged in each traversing hydraulic cylinder. Compared with the prior art, the working roll traversing device has the advantages that: 1) the axial central lines of the traversing hydraulic cylinders are coaxial with the axial central line of the movable block in the device, so moment is effectively avoided in the running process of equipment, the abrasion of parts of the equipment is reduced, and maintenance fund is saved; therefore, product yield is improved; 2) the integrated lock hydraulic cylinder is adopted in the device, so the phenomenon of oil leakage of the lock hydraulic cylinder can be effectively avoided, and the working roll traversing device has long service life, is convenient to maintain and replace, and saves time and labor; and therefore, production efficiency is improved.
Description
Technical field
The utility model relates to hot-strip production equipment field, particularly a kind of work roll shifting device of strip finishing mill.
Background technology
In hot rolling line,, need to adopt the work roll shifting device to guarantee hot rolled strip dimensional accuracy of products and strip shape in the finishing stand, but there is following drawback in traditional work roll shifting device in order to control product percent of pass and cost:
1) traversing hydraulic cylinder axis and movable block axis disalignment produce side direction moment when traversing, make between movable block and fixed block to exist extruding force to cause jam, cause the main parts size wearing and tearing very fast, and maintenance cost is higher, influences final product quality.
2) split type working roll is laterally locked hydraulic cylinder has oil leakage phenomenon, makes traversing hydraulic cylinder push-pull effort unstable, the corresponding hysteresis of working, the locking hydraulic cylinder is low service life, maintenance is wasted time and energy, pollutes bigger, the maintenance cost height.
Therefore, need a kind of simple in structure, practical, safe and reliable device on the hot rolling frame, and then improve the quality of products.
Summary of the invention
The purpose of the utility model provides a kind of work roll shifting device of strip finishing mill; This device has effectively solved the problem that traversing hydraulic cylinder and movable block disalignment cause producing when traversing moment; And this device is simple and practical, and is reasonable in design, effectively raises product quality.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of work roll shifting device of strip finishing mill; Comprise fixed block, traversing hydraulic cylinder, movable block, locking hydraulic cylinder; Described fixed block is connected with traversing hydraulic cylinder; Traversing hydraulic cylinder and movable block are hinged, and the longitudinal center line of traversing hydraulic cylinder and movable block point-blank, are provided with whole locking hydraulic cylinder in the described movable block.
Be provided with displacement transducer in the described traversing hydraulic cylinder.
Compared with prior art; The utility model has the advantages that: 1) traversing hydraulic cylinder is coaxial with the longitudinal center line of movable block in this device, effectively prevents in the equipment moving process, to produce moment, reduces the wearing and tearing of equipment part; Practice thrift maintenance fund, and then improved product percent of pass; 2) the locking hydraulic cylinder adopts monoblock type in this device, has effectively prevented locking hydraulic cylinder oil leakage phenomenon, and the life-span is long, and convenient maintenance and replacement, and is time saving and energy saving, and then improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the traversing hydraulic cylinder 3-of 1-fixed block 2-movable block 4-locks hydraulic cylinder
The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
Embodiment one, and a kind of work roll shifting device of strip finishing mill is seen Fig. 1; Comprise fixed block 1, traversing hydraulic cylinder 2, movable block 3, locking hydraulic cylinder 4; Fixed block 1 is connected with traversing hydraulic cylinder 2, and traversing hydraulic cylinder 2 is hinged with movable block 3, and the longitudinal center line of traversing hydraulic cylinder 2 and movable block 3 point-blank; Be provided with whole locking hydraulic cylinder 4 in the movable block 3, be provided with displacement transducer in the traversing hydraulic cylinder 4.
This installs in use, and fixed block 1 is fixing closing with rolling-mill housing, and movable block 3 is accepted working roll system and can be driven working roll and ties up in the fixed block 1 traversing.Traversing hydraulic cylinder 2 is installed in fixed block 1 inboard, makes traversing hydraulic cylinder 2 center lines coaxial with movable block 3 center lines, and traversing hydraulic cylinder 2 piston rods are fixed on the fixed block 1 with the sphere cover; Traversing hydraulic cylinder 2 bodies and movable block 3 spheres are hinged; Guaranteeing in the traversing process can automatic aligning, subsidiary displacement transducer, the accurately traversing amounts of feedback operation roller in the traversing hydraulic cylinder 2; If recording the displacement and the setting value of traversing hydraulic cylinder 2, displacement transducer is not inconsistent, then compensation automatically.In movable block 3, adopt whole locking hydraulic cylinder 4, adopt static seal to prevent hydraulic fluid leak between locking hydraulic cylinder 4 drum outer walls and the movable block 3, and locking hydraulic cylinder 4 can be from movable block 3 inboard integral disassembly, assemblies.In the normal rolling course of work; Locking hydraulic cylinder 4 piston rod front ends put in the working roll bearing block; Making locking hydraulic cylinder 4 drive working roll is to be synchronized with the movement to realize laterally moving of working roll; When changing working roll, locking hydraulic cylinder 4 piston rods retraction is thrown off with working roll bearing block, and working roll and movable block break away from gets in touch.
