Abstract
An improved cold rolling galvanized immersing roller connecting device belongs to the technical field of rolling mills, and aims to resolve the technical problem of providing an immersing roller connecting device capable of avoiding corrosion of liquid zinc to rollers, prolonging service life of the rollers and increasing product quality of the rollers. The technical scheme includes that the immersing roller connecting device consists of a half bearing, lateral baffle plates, a shaft-end arc-surface baffle block, an immersing roller shaft sleeve, a lining tile, a supporting arm and a bottom support. The improvement of the immersing roller connecting device includes that one end of the immersing roller shaft sleeve which is connected with an immersing roller shaft neck is provided with a convex circumferential flange, and the flange is in welding connection with the immersing roller shaft neck. Because the immersing roller shaft sleeve and the immersing roller shaft neck are in welding connection, the liquid zinc can not enter the shaft sleeve through a clearance between the immersing roller shaft sleeve and the immersing roller shaft neck, thereby avoiding corrosion to the root portion of the immersing roller, greatly reducing fracture of the shaft end of the immersing roller, decreasing economic loss caused by scrap coiling, band steel damages and the like because of changing rollers, increasing production efficiency and reducing cost.
Description
Technical field
The utility model relates to a kind ofly installs localized device with cold-rolling galvanization submergence roller, belongs to the steel rolling equipment technical field.
Background technology
In the production of cold-reduced sheet, the zinc-plated technological process that is absolutely necessary of cold-reduced sheet.By production practice, operator find that aborning there is the following shortcoming in the submergence roller that adopts at present:
1. submergence roller and submergence roll sleeve have axial linear expansion aborning, because swell increment difference, zinc liquid can enter in the slit of axle sleeve and roller end, form the corrosion of submergence roller root, cause the root strength reduction, produce stress concentration, in the process of operation, can produce the fracture of submergence roll shaft end;
2. the design of axle head cambered surface block is unreasonable, and this shape causes after producing for some time, can come off or produce big friction, makes the submergence roller amesiality, causes stuck or the scuffing of band steel;
3. the sleeve wall of submergence roll sleeve is thin, and the radial swelling ability that absorbs submergence roll shaft neck is low, in use ftractures easily;
4. what halfliner was done is thick partially, and making toos many or too much for use at every turn must change, and causes very big waste.
The existence of these shortcomings has had a strong impact on the quality of the stable and product of producing, and is necessary to take improved measure.
Summary of the invention
Technical problem to be solved in the utility model provides a kind ofly can avoid the work-ing life that zinc liquid pair of rollers burn into improves roller and the improved cold-rolling galvanization submergence roller coupling device of quality product.
The technical scheme that solves the problems of the technologies described above is:
A kind of improved cold-rolling galvanization submergence roller coupling device, it is made up of halfliner, side shield, axle head cambered surface block, submergence roll sleeve, lining tile, support arm, collet, its improvements are, its submergence roll sleeve be connected with submergence roll shaft neck an end have the projection circumferential flange, flange and submergence roll shaft neck are welded to connect.
Above-mentioned improved cold-rolling galvanization submergence roller coupling device, the surface of described axle head cambered surface block is whole global face shape.
This submergence roller coupling device is welded to connect because submergence roll sleeve and axle journal adopt, and zinc liquid can not enter in the axle sleeve by the gap of submergence roll sleeve and axle journal, has avoided the corrosion to submergence roller root, has significantly reduced the generation of submergence roll shaft end phenomenon of rupture; The axle head cambered surface changes whole global face into by hemisphere face, has eliminated because of the original design improper stuck or band steel scuffing problem that causes.After adopting this structure, reduced, reduced cost because the financial loss of generations such as the useless volume of roll change, roll change generation, the scuffing of band steel has improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Mark is as follows among the figure: halfliner 1, side shield 2, axle head cambered surface block 3, submergence roll sleeve 4, lining tile 5, support arm 6, location parting bead 7, collet 8, bearing shell welding block 9, submergence roller 10
Embodiment
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A sectional view of Fig. 1, and Fig. 1 also is the B-B sectional view of Fig. 2 simultaneously.
In embodiment of the present utility model, in order to prevent zinc liquid to immerse the root of axle journal, root at submergence roll sleeve 4 increases flange arrangement, weld in order to install and to be convenient to, increase submergence roller 10 two end axles electrical path length sizes, and carry out chamfering in submergence roller 10 two ends conical end, and so just can the shaft shoulder of flange periphery and roller is welded together. avoid the corrosion of axle journal being produced roll breakage because zinc liquid immerses to cause in the axle sleeve.
In order to have eliminated because of the original design improper stuck or band steel that causes scratches problem, also carried out corresponding modification for roller axle end cambered surface block 3, partial sphere is revised becomes whole sphere.
The cracking problem of the submergence roll sleeve 4 that the utility model causes for the compensate for coefficient of thermal expansion difference is at first made amendment to the wall thickness and the external diameter of axle sleeve, has strengthened wall thickness and external diameter.In addition in order to improve the service efficiency of halfliner 1, the thickness of halfliner 1 is reduced, because above-mentioned modification is constant for the central position that keeps submergence roller 10, the scantlings of the structure of lining tile 5 and collet 8 and side shield 2 has been carried out corresponding modification.The axle sleeve material has become cobalt base alloy by Si Taili alloy 12, saves cost, reduces spare parts consumption.
The halfliner 1 that shows in Fig. 1,2, side shield 2, lining tile 5, support arm 6, location parting bead 7, collet 8, bearing shell weld block 9, submergence roller 10 is all same as the prior art, repeat no more.
