Abstract
The invention discloses a forming bearing roller of a forming machine of a helical weld pipe unit. The forming bearing roller of the forming machine of the helical weld pipe unit is characterized in that a bearing roller outer ring, two end face check rings, a bearing roller inner ring and a plurality of cylindrical rollers are included. The cylindrical rollers are arranged between the bearing roller outer ring and the bearing roller inner ring. The inner side of the bearing roller outer ring is of a raised-shaped structure, one face of each end face check ring protrudes outwards, the convex faces of the two end face check rings are both inward, and the two end face check rings are mounted on the two sides of the bearing roller inner ring. When the forming bearing roller of the forming machine of the helical weld pipe unit works, stress of all the components of the forming bearing roller is greatly improved, the service life of the single forming bearing roller is prolonged, unit production cost can be controlled, meanwhile, product quality is guaranteed, and the requirement for producing spiral seam submerged-arc welding steel tubes with high strength and thick walls can be met.
Description
Technical field
The present invention relates to a kind of format roll of spiral weld-pipe mill former, relate in particular to a kind of shaping axle runner of spiral weld-pipe mill composing type device.
Background technology
Spiral seam steel pipe submerged arc is with the forming angle of determining, to bend to the pipe of determining caliber with the steel band of certain width through three-roll bending machine, carry out again the steel pipe that inside and outside submerged arc welding forms, in manufacturing spiral welded pipe process, the effect of former is that steel band continuous cold bending deformation is become to spiral pipe, steel pipe type body size (caliber, misalignment, stick up chew, ovality etc.) all in this process, form, tube quality is played to conclusive effect, so former is extremely important; What in former, bear steel band flexural deformation power is moulding pony roll, the assembly that the little roll structure originally using is roller shell and bearing, but along with the needs of client to high strength, thick walled steel tube, pony roll is stressed increasing, shorten service life, after breaking down, to steel pipe's production and product quality, all will impact.
Summary of the invention
Object of the present invention is just to provide in order to address the above problem a kind of shaping axle runner of spiral weld-pipe mill composing type device.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of shaping axle runner of spiral weld-pipe mill composing type device, comprise bearing roller outer ring, two end face back-up rings, bearing roller inner ring and a plurality of cylindrical rollers, a plurality of described cylindrical rollers are arranged between described bearing roller outer ring and described bearing roller inner ring, the inner side of described bearing roller outer ring is convex structure, an evagination of described end face back-up ring, the convex surface of two described end face back-up rings is all inside, and is arranged on the both sides of described bearing roller inner ring.
The present invention unites two into one the roller shell and the outer bridge of bearing that are arranged on outside bearing, outside former plain bearing, on Bridge Foundation, strengthens, and each parts of whole bearing is strengthened simultaneously, thereby obtained a reinforced bearing roller, and its intensity is greatly improved.
Particularly, described shaping axle runner also comprises a plurality of steel balls, and a plurality of described steel balls are evenly arranged on the end that contacts of described bearing roller outer ring and described end face back-up ring, and described steel ball can be assisted and be born axial force; A plurality of described cylindrical rollers divide two rows to be arranged between described bearing roller outer ring and described bearing roller inner ring, the active force bearing to reduce single roller.
Particularly, described shaping axle runner also comprises a plurality of O RunddichtringOs, is provided with groove ring on the circumference of described end face back-up ring, and a plurality of described O RunddichtringOs are arranged in described groove ring.
Beneficial effect of the present invention is:
The shaping axle runner of spiral weld-pipe mill composing type device of the present invention is when work, each parts of shaping axle runner stressed obtained larger improvement, improved the service life of single shaping axle runner, make the unit cost of production controlled, make product quality have assurance simultaneously, can meet the demand of the spiral seam steel pipe submerged arc of production high strength, thick walled steel tube.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the shaping axle runner of spiral weld-pipe mill composing type device of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described in detail:
As shown in Figure 1, the shaping axle runner of spiral weld-pipe mill composing type device of the present invention, comprise bearing roller outer ring 1, two end face back-up rings 2, bearing roller inner ring 3 and a plurality of cylindrical rollers 4, a plurality of cylindrical roller 4 compactnesses are arranged between bearing roller outer ring 1 and bearing roller inner ring 3 uniformly, the inner side of bearing roller outer ring 1 is convex structure, an evagination of end face back-up ring 2, the convex surface of two end face back-up rings 2 is all inside, and is arranged on the both sides of bearing roller inner ring 3.
Shaping axle runner also comprises a plurality of O RunddichtringOs 5, is provided with groove ring on the circumference of end face back-up ring 2, and a plurality of O RunddichtringOs 5 are arranged in groove ring.
The present invention unites two into one the roller shell and the outer bridge of bearing that are arranged on outside bearing, outside former plain bearing, on Bridge Foundation, strengthens, and each parts of whole bearing is strengthened simultaneously, thereby obtained a reinforced bearing roller, and its intensity is greatly improved; From reducing cost, by the structural design of whole shaping axle runner, be detachable, dismounting lower surface back-up ring 2 can be changed all parts of shaping axle runner simultaneously, and a plurality of O RunddichtringOs 5 can guarantee the sealing to shaping axle runner simultaneously.
Shaping axle runner also comprises a plurality of steel balls 6, and a plurality of steel balls 6 are evenly arranged in the end that contacts of bearing roller outer ring 1 and end face back-up ring 2, and steel ball 6 can be assisted and be born axial force; A plurality of cylindrical rollers 4 between bearing roller outer ring 1 and bearing roller inner ring 3 are set to double, the active force bearing to reduce single roller; Simultaneously because the load that shaping axle runner bears is low-speed heave-load, so the lubricating grease that shaping axle runner adopts is the wear-resisting lubricating grease of high viscosity.
The installing space of shaping axle runner is limited, very narrow and small, so it bears very large normal pressure, the very severe that simultaneously its working environment becomes because of the impact of steel plate iron rust and solder flux dust etc., what adopt that shaping axle runner of the present invention can make its each parts has stressedly obtained larger improvement, can be reduced to a certain extent the width of profile shaft runner simultaneously, in equal length scope, with respect to common format roll, can arrange more shaping axle runner, make the whole stressed improvement obtaining to a certain extent of shaping axle runner.
