Abstract

The utility model discloses a special-shaped core roller for a ring rolling mill. The core roller comprises a core roller body; the core roller body comprises a first cylinder segment, an annular groove, a second cylinder segment, smooth transition parts and a shaft shoulder, wherein the annular groove is perpendicularly formed between the first cylinder segment and the second cylinder segment, the smooth transition parts are arranged on the joint portion between the annular groove and the first cylinder segment and between the annular groove and the second cylinder segment, the shaft shoulder is arranged at the lower end of the second cylinder segment, the smooth transmission part is arranged on the outer side of the lower end of the first cylinder segment, and the smooth transition part is arranged on the outer side of the upper end of the second cylinder segment. Because the inner circle of an annular blank is rolled into a boss through the annular groove, machining work hours can be reduced, energy consumption is saved, cost is lowered, and production efficiency is improved; meanwhile, an annular forge piece is uniform in density, the quality of the annular forge piece is guaranteed, and the market competitiveness and the market occupancy of the annular forge piece are increased; the special-shaped core roller for the ring rolling mill is simple in structure and high in practicality and has high promotion and application value.

Description

Special-shaped core roller for a kind of ring rolls
Technical field
The utility model relates to metal forming machinery part technical field, particularly relate to special-shaped core roller for a kind of ring rolls.
Background technology
Forging process product is that current use amount is large, the industrial products of wide application.At present, the feature of relatively large ring forgings product is: wide in variety, few, different in batches.Along with the development of ring forging technology and fierce market competition, in order to save material, to reduce the cost that postorder is processed, start to produce forging special-shape ring, especially, in large-scale ring forging is produced, save lot of materials and also reduce the cost of postorder processing.In prior art, numerical control rolling machine is rolled over and made the core roller using in type is all straight core roller, by such shaped device unification, rolling ring is rolled over to the type of making, then by turning, to rolling over ring, process the shape of requirement, in process, can cause the waste of blank, roll over ring Density inhomogeneity, and long processing time, inefficiency, rolling ring is of low quality.
Therefore, for above-mentioned situation, design saving raw material, improve the special-shaped core roller for a kind of ring rolls of forging quality and production efficiency, just inventor's problem to be solved.
Utility model content
The technical problem that the utility model mainly solves is to provide special-shaped core roller for a kind of ring rolls, can save raw material, reduces process time, improves forging density, has guaranteed quality and the production efficiency of forging.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: special-shaped core roller for a kind of ring rolls is provided, comprise core roller main body, described core roller main body comprises the first shell portion, annular groove, the second shell portion, rounding off and the shaft shoulder, between described the first shell portion and the second shell portion, be vertically installed with annular groove, described annular groove and the first shell portion and the second shell portion junction are provided with rounding off, the described shaft shoulder is arranged at the lower end of the second shell portion, the lower end arranged outside of described the first shell portion has rounding off, the upper end arranged outside of described the second shell portion has rounding off.
In preferred embodiment of the utility model, the diameter of described the first shell portion is identical with the diameter of the second shell portion.
The beneficial effects of the utility model are:
The utility model can be rolled over ring blank inner ring to make boss-shaped by the annular groove of described core roller main body, the a large amount of wastes in turning process have been avoided, also reduced machining period, save significantly energy consumption, reduce costs, and effectively improved production efficiency, simultaneously, solved the problem of the ring blank processing capacity inequality that traditional handicraft processes, realize ring forging even density, guaranteed the quality of ring forging, increased the market competitiveness and the occupation rate of market of ring forging; This core roll structure is simple, practical, has stronger propagation and employment and is worth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be shown in the rolling process schematic diagram processed of forging special-shape ring;
Fig. 3 is forging special-shape ring schematic diagram;
In accompanying drawing, the mark of each parts is as follows: 1, core roller main body 2, the first shell portion 3, annular groove 4, the second shell portion 5, rounding off 6, the shaft shoulder.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1 to Fig. 3, the utility model embodiment comprises: core roller main body 1, described core roller main body 1 comprises the first shell portion 2, annular groove 3, the second shell portion 4, rounding off 5 and the shaft shoulder 6, between described the first shell portion 2 and the second shell portion 4, be vertically installed with annular groove 3, described annular groove 3 and the first shell portion 2 and the second shell portion 4 junctions are provided with rounding off 5, the described shaft shoulder 6 is arranged at the lower end of the second shell portion 4, the lower end arranged outside of described the first shell portion 2 has rounding off 5, the upper end arranged outside of described the second shell portion 4 has rounding off 5.
In preferred embodiment of the utility model, the diameter of described the first shell portion 2 is identical with the diameter of the second shell portion 4.
As shown in Figure 2, more prefabricated ring base is enclosed within to the outer shroud of annular groove 3, then Ring Rolling Machine is rolled over ring-rolling.In the operation of rolling, by the roll-force effect of king roller and core roller main body 1, ring base is subject to radial and axial spreading distortion, when radially growing up, progress into annular groove 3, its radial end face produces local plastic deformation, and diameter constantly expands, and finally obtains the geomery of design.
The utility model can be rolled over ring blank inner ring to make boss-shaped by the annular groove 3 of described core roller main body 1, the a large amount of wastes in turning process have been avoided, also reduced machining period, save significantly energy consumption, reduce costs, and effectively improved production efficiency, simultaneously, solved the problem of the ring blank processing capacity inequality that traditional handicraft processes, realize ring forging even density, guaranteed the quality of ring forging, increased the market competitiveness and the occupation rate of market of ring forging; This core roll structure is simple, practical, has stronger propagation and employment and is worth.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
