Abstract
The invention discloses a special-shaped core roller for a ring rolling mill, and belongs to the technical field of components of forging and pressing machinery. The special-shaped core roller comprises a core roller body. The core roller body comprises connecting portions and a working portion, the connecting portions are arranged at two ends of the working portion and mainly comprise mandrels, the working portion comprises a cylinder section and truncated cone sections, two ends of the cylinder section are connected to the bottoms of the truncated cone sections, and the tops of the truncated cone sections are connected to the connecting portions. Owning to the mode, the special-shaped core roller has the advantages that blanks of ring pieces can be rolled and formed by the aid of the special-shaped core roller, huge waste in turning procedures can be prevented, machining working hours can be reduced, energy consumption can be decreased to a great extent, the cost can be lowered, and the production efficiency can be effectively improved; the problem of uneven machining volumes of blanks of ring pieces machined by the aid of the traditional technologies can be solved, the ring forged pieces are uniform in density, and accordingly the quality of the ring forged pieces can be guaranteed; the special-shaped core roller is simple in structure and high in practicality and has high popularization and application value.
Description
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, manhole is made in the endoporus rolling of rolling over 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 connecting portion and operate portions, described connecting portion is arranged at the two ends of operate portions, and described connecting portion mainly comprises mandrel, and described operate portions is made up of shell portion and frustoconical section, the two ends of described shell portion are all connected to the bottom surface of frustoconical section, and the end face of described frustoconical section is connected to connecting portion.
In a preferred embodiment of the present invention, described frustoconical section is at least 2, and described frustoconical section is all parallel to shell portion; The stepped structure of described core roller main body.
The invention has the beneficial effects as follows:
1, compared to prior art in core roller, can reserve a large amount of allowance after roll off ring blank, the turning process needed for following process can spend longer process time, and wastes a lot of materials in turning process.And the rolling of the internal via shape of ring blank can be made type by the operate portions of described core roller main body 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 special-shaped core roll structure is simple, practical, has stronger propagation and employment and is worth.

Fig. 2 is shown interior forging special-shape ring schematic diagram;
Fig. 3 be depicted as Fig. 1 A to schematic diagram;
Fig. 4 is the B-B sectional structure schematic diagram being depicted as Fig. 1;
In accompanying drawing, the mark of each parts is as follows: 1, core roller main body 2, operate portions 3, connecting portion 4, shell portion 5, frustoconical section 6, mandrel.
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. 4, the embodiment of the present invention comprises: core roller main body 1, described core roller main body 1 comprises connecting portion 3 and operate portions 2, described connecting portion 3 is arranged at the two ends of operate portions 2, described connecting portion 3 mainly comprises mandrel 6, described operate portions 2 is made up of shell portion 4 and frustoconical section 5, and the two ends of described shell portion 4 are all connected to the bottom surface of frustoconical section 5, and the end face of described frustoconical section 5 is connected on mandrel 6.
In a preferred embodiment of the present invention, described frustoconical section 5 is at least 2, and described frustoconical section 5 is all parallel to shell portion 4; The stepped structure of described core roller main body 1.
Ring blank after heating is enclosed within core roller main body 1 by the present invention, described core roller main body 1 is tangent with ring blank inner edge, then described core roller main body 1 rotates together with ring blank, operate portions 2 contacts with ring blank and rolloff in the process of feeding, under the effect of operate portions 2, the wall thickness of ring blank reduces, and internal diameter expands, axial height is constant, and the endoporus of ring blank is rolled over and made type.The step structure of described core roller main body 1 can be saved raw material, reduce production cost.
Core roller compared to prior art, can reserve a large amount of allowance after roll off ring blank, and the turning process needed for following process can spend longer process time, and wastes a lot of materials in turning process.And the rolling of the internal via shape of ring blank can be made type by the operate portions 2 of described core roller main body 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 special-shaped 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.
