Abstract

The invention discloses a special-shaped core roller for a ring rolling mill. The special-shaped core roller comprises a core roller body. The core roller body comprises a first cylinder section, an annular groove, a second cylinder section, smooth transition sections and a shaft shoulder, the annular groove is perpendicularly formed in a position between the first cylinder section and the second cylinder section, the corresponding smooth transition sections are arranged at joints of the annular groove, the first cylinder section and the second cylinder section, the shaft shoulder is arranged at the lower end of the second cylinder section, the corresponding smooth transition section is arranged on the outer side of the lower end of the first cylinder section, and the corresponding smooth transition section is arranged on the outer side of the upper end of the second cylinder section. The special-shaped core roller has the advantages that inner rings of blanks of ring pieces can be rolled by the aid of the annular groove to form bosses, accordingly, machining working hours can be reduced, energy consumption can be decreased, the cost can be lowered, and the production efficiency can be improved; the ring forged pieces are uniform in density, accordingly, the quality of the ring forged pieces can be guaranteed, the market competitiveness of the ring forged pieces can be improved, and the market share of the ring forged pieces can be increased; the special-shaped core roller is simple in structure and high in practicality and has high popularization and application value.

Description

The special-shaped core roller of a kind of ring rolls
Technical field
What the present invention relates to is metal forming machinery part technical field, particularly relates to the special-shaped core roller of 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, and batch is few, different.Along with development and the fierce market competition of ring forging technology, in order to save material, reduce the cost of postorder processing, start to produce forging special-shape ring, especially in large-scale ring forging is produced, save lot of materials and reduce the cost of postorder processing.In prior art, numerical control rolling machine is rolled over and made the core roller used in type is all straight core roller, by such shaped device unification, type is made in the rolling of rolling ring, then by turning, rolling ring is processed to the shape of requirement, the waste of blank can be caused in process, roll over ring Density inhomogeneity, and long processing time, inefficiency, rolling ring is of low quality.
Therefore, design saving raw material for above-mentioned situation, improve the special-shaped core roller of a kind of ring rolls of forging quality and production efficiency, inventor's problem to be solved just.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the special-shaped core roller of a kind of ring rolls, can save raw material, reduces process time, improves forging density, ensure that quality and the production efficiency of forging.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of ring rolls special-shaped core roller, comprise core roller main body, described core roller main body comprises the first shell portion, annular groove, second shell portion, rounding off and the shaft shoulder, annular groove is vertically installed with between described first shell portion and the second shell portion, 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 outside of described first shell portion is provided with rounding off, the upper end arranged outside of described second shell portion has rounding off.
In a preferred embodiment of the present invention, the diameter of described first shell portion is identical with the diameter of the second shell portion.
The invention has the beneficial effects as follows:
Ring blank inner ring can be rolled over by the annular groove of described core roller main body and be made boss-shaped by the present invention, avoid a large amount of wastes in turning process, decrease machining period, save energy consumption significantly, reduce costs, and effectively improve production efficiency, simultaneously, solve the problem of the ring blank processing capacity inequality that traditional handicraft processes, achieve ring forging even density, ensure that the quality of ring forging, add 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 invention;
Fig. 2 is the rolling process schematic of shown 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, first shell portion 3, annular groove 4, second shell portion 5, rounding off 6, the shaft shoulder.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises: core roller main body 1, described core roller main body 1 comprises the first shell portion 2, annular groove 3, second shell portion 4, rounding off 5 and the shaft shoulder 6, annular groove 3 is vertically installed with between described first shell portion 2 and the second shell portion 4, described annular groove 3 and the first shell portion 2 and the second shell portion 4 junction 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 outside of described first shell portion 2 is provided with rounding off 5, the upper end arranged outside of described second shell portion 4 has rounding off 5.
In a preferred embodiment of the present invention, the diameter of described 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 the outer shroud of annular groove 3, then Ring Rolling Machine rolles 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, annular groove 3 is progressed into while radially growing up, its radial end face produces local plastic deformation, and diameter constantly expands, and finally obtains the geomery designed.
Ring blank inner ring can be rolled over by the annular groove 3 of described core roller main body 1 and be made boss-shaped by the present invention, avoid a large amount of wastes in turning process, decrease machining period, save energy consumption significantly, reduce costs, and effectively improve production efficiency, simultaneously, solve the problem of the ring blank processing capacity inequality that traditional handicraft processes, achieve ring forging even density, ensure that the quality of ring forging, add 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 embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; 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 invention.
