Description
Technical field
The utility model relates to the roller surfaces surfacing equipment, relates in particular to thin-walled and the major diameter roller surface overlaying equipment of being applicable to.
Background technology
The reparation of general hollow built-up welding roller or making all adopt the mode of inner support web to control welding deformation.Inner fagging is connected by weld seam with body of roll cylindrical shell, thereby built-up welding finishes after the back gas cutting is removed fagging mandrel making finished product roller to be installed again.There is following shortcoming in such fagging form: can not utilize once more after 1) fagging cuts off, cause waste; 2) fagging quantity is difficult for too much the Deformation Control ability being restricted; 3) there are adverse effects such as distortion in the welding process of the fagging and the body of roll to the body of roll; 4) few support makes body of roll built-up welding distortion big, and the welding material demand that reaches requirement built-up welding size increases, and causes the welding material cost to increase.Be head it off, on the design of reusable roller disc, people once did many trials, but applicable scope all is limited, and especially the support disc for thin-walled or the practicality of major diameter roller does not have good solution.
Summary of the invention
The utility model is intended to address the deficiencies of the prior art, and provides a kind of thin-walled and the surface overlaying of major diameter roller reusable disc supporting construction.The utility model is fit to the built-up welding of thin-walled or major diameter roller, and enough support forces can be provided, and can realize does not have installation, the dismounting that destroys, reusable, reduction manufacturing cost.
The utility model is achieved in that
The reusable disc supporting construction of a kind of thin-walled and the surface overlaying of major diameter roller, elongated to support that the roll surface mode is arranged on roller inside, it comprises some circular disc, adjacent disc external diameter position is fixedly connected by location-plate, and it also comprises steel pipe and the some wedges that is arranged on the disc center;
Described circular disc is put together by some identical fanning strips, each fanning strip comprises two support bar and arc sections with certain angle, and being provided with a wedge between the relative joint face of per two each and every one fanning strip arc section amalgamations, described steel pipe passes center and fixedly connected each disc of the circular disc that each fanning strip pieces together.
The reusable disc supporting construction of described thin-walled and the surface overlaying of major diameter roller,, described fanning strip has the annular sector structure, and the arc surface of center is spliced into a circle, with the inner surface of this circle described steel pipe that is fixedly connected, and their connect opposite face and also are provided with wedge.
The reusable disc supporting construction of described thin-walled and the surface overlaying of major diameter roller, described fanning strip have three to eight, and each fanning strip is provided with the reinforcement that is provided with along radial direction.
The reusable disc supporting construction of described thin-walled and the surface overlaying of major diameter roller, described each wedge is connected with the weldering of secter pat arc end millet cake.
The reusable disc supporting construction of described various thin-walled and the surface overlaying of major diameter roller, its, described fanning strip is a sheet material, the be spliced full circle of a support rollers inner surface of each fanning strip and wedge.
The utility model uses wedge structure to regulate the fagging diameter cleverly and the support force of the body of roll is provided, inner fagging is by the identical assembly of a plurality of structures, be that a plurality of covering of the fans are connected and form, but in actual applications, can be according to the difference of roll body physical dimension, come the quantity and the size of adjusting part, to satisfy instructions for use.Different with the web pattern form of routine, the cylindrical of this support (each assembly) is by several plectane faces (roll and form) and be stitched together (comprise inner reinforcing plate structure).This design form has increased lifting surface area (having increased Area of bearing), and the problem of the body of roll curve deformation that is caused for the web pattern form of routine has good improvement.The structure of internal side diameter, then steel pipe and the corresponding reinforcing plate structure by each sector constitutes.Noticing the structure home position, is a steel pipe, and the disc modular construction of this steel pipe and both sides is fixed together.When work, the internal side diameter structure ring is buckled on the steel pipe of the center of circle, wedges wedge afterwards between adjacent two sector structures of internal side diameter, circumferentially playing fixing effect on the one hand, on the other hand, make the external diameter of sector structure increase, guarantee the excellent support of the body of roll.Simultaneously, also wedge wedge, guarantee circumferential fixing at outside diameter.It should be noted that after the wedge wedging, need spot welding, in order to avoid wedge comes off when the body of roll must expand with heat and contract with cold.When body of roll welding finishes, only need take off wedge, total just is easy to pull down.And be not damaged, when carrying out the built-up welding of same specification roller class next time, can reuse.
