Abstract

The utility model discloses a special-shaped core roller for a ring rolling mill and belongs to the technical field of parts of forging machines. The core roller comprises a core roller body. The core roller body comprises connecting parts and a working part, wherein the connecting parts are arranged at the two ends of the working part; each connecting part mainly comprises a mandrel; the working part is composed of a cylinder segment and a truncated cone segment, both the two ends of the cylinder segment are connected to the bottom surface of the truncated cone segment, and the top surface of the truncated cone segment is connected to the connecting parts. Through the method, an annular blank can be formed in a rolling mode, a large amount of waste can be avoided in the turning process, machining work hours are also reduced, energy consumption is saved and cost is lowered to a large extent, and production efficiency is effectively improved; meanwhile, the core roller solves the problem that an annular blank machined through the traditional technology is not uniform in machining amount, an annular forge piece is uniform in density, and the quality of the annular forge piece is guaranteed; the special-shaped core roller 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, the endoporus of rolling over ring is rolled over and made manhole, 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.
Summary of the invention
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 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 comprised of shell portion and frustoconical section, the two ends of described shell portion are all connected in the bottom surface of frustoconical section, and the end face of described frustoconical section is connected in connecting portion.
In preferred embodiment of the utility model, 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 beneficial effects of the utility model are:
1, the core roller in compared to prior art, can reserve a large amount of allowance after roll off ring blank, and the required turning process of following process can spend longer process time, and in turning process, has wasted a lot of materials.And the utility model can be rolled over the interior hole shape of ring blank by the operate portions of described core roller main body the type of making, 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 abnormal shape 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 forging special-shape ring schematic diagram;
Fig. 3 is depicted as the A of Fig. 1 to schematic diagram;
Fig. 4 is the B-B sectional structure schematic diagram that is 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.
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. 4, the utility model embodiment 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 comprised of shell portion 4 and frustoconical section 5, and the two ends of described shell portion 4 are all connected in the bottom surface of frustoconical section 5, and the end face of described frustoconical section 5 is connected on mandrel 6.
In preferred embodiment of the utility model, described frustoconical section 5 is at least 2, and described frustoconical section 5 is all parallel to shell portion 4; Described core roller main body 1 stepped structure.
The utility model is enclosed within the ring blank after heating in core roller main body 1, described core roller main body 1 is tangent with ring blank inner edge, then described core roller main body 1 is rotated 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 the type of making.The step structure of described core roller main body 1 can be saved raw material, reduce production costs.
Core roller compared to prior art, can reserve a large amount of allowance after roll off ring blank, and the required turning process of following process can spend longer process time, and in turning process, has wasted a lot of materials.And the utility model can be rolled over the interior hole shape of ring blank by the operate portions 2 of described core roller main body the type of making, 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 abnormal shape 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.
