Abstract
The utility model discloses a conical roller die for a large-size flange ring rolling mill. The conical roller die comprises an upper conical roller body and a lower conical roller, wherein the upper conical roller body is inlaid with a conical roller die sleeve which is provided with an annular concave platform at the rear part of the sleeve; the conical roller die sleeve in front of the annular concave platform is provided with an inclination; and the annular concave platform is provided with an arc transition at corners thereof. Compared with the prior art, the conical roller die for the large-size flange ring rolling mill has such outstanding beneficial effects that the conical roller die reduces raw material consumption and processing cost, reduces labor intensity, saves time, has advantages of convenient use, simple structure and wide application range, and can be used for rolling annular parts with different specifications.
Description
Technical field
The utility model relates to a kind of process equipment of flange ring, is specifically related to the awl roller die on a kind of large scale flange ring milling train.
Background technology
At present, large scale flange ring milling train used roll when axial roll compacting is straight line awl roller, the annular forging piece of roll forming; Its upper and lower end face all is parallel planes; And for the workpiece that hub is arranged outside the end faces such as rolling wind power tower flange, also need again parallel plane is processed, be processed into the workpiece that there is hub in the outside; So just increase raw materials consumption and processing charges, but also increased labour intensity and time.At present, also there is not good solution.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, and the awl roller die on a kind of large scale flange ring milling train is provided, and this awl roller die has and reduced raw materials consumption and processing charges, reduces labour intensity, the characteristics of having saved the time.
For realizing above-mentioned purpose; The technical scheme of the utility model is the awl roller die on a kind of large scale flange ring milling train of design; Said awl roller die comprises the epicone roller body and bores roller down; It is characterized in that, on said epicone roller body, be inlaid with awl roller die cover, be provided with annular concave platform at the rear portion of said awl roller die cover.
Wherein optimized technical scheme is, the awl roller die cover of said annular concave platform front side is provided with gradient, is provided with arc transition at the edge of annular concave platform.
The advantage and the beneficial effect of the utility model are: the awl roller die on this large scale flange ring milling train compared with prior art; Has following outstanding beneficial effect: reduced raw materials consumption and processing charges, reduced labour intensity, saved the time; Easy to use; Simple in structure, applied widely, can be used for the characteristics such as annular element of rolling different size.
Description of drawings
Fig. 1 is the structural representation of the awl roller die on the big cun flange ring milling train of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
As shown in Figure 1, the utility model is the awl roller die on a kind of big cun flange ring milling train, and its awl roller die comprises awl roller body 1 and bores roller 5 down, on described awl roller body 1, is inlaid with awl roller die cover, is provided with annular concave platform 2 at the rear portion of said awl roller die cover.
The awl roller die cover of said annular concave platform front side is provided with gradient, is provided with arc transition 4 at the edge of annular concave platform.Make the end face outside that the hub place smooth transition of the workpiece of hub arranged, burr can not occur, use safer.
The large-scale ring rolling machine of a utility model awl volume mold work process: at first with workpiece 6 handlings to the collars machine, place awl roller body 1 and down between the awl volumes 5, start the collars machine and begin rolling; In radial rolling, axially also carry out rolling, through the position of adjustment workpiece 6 on awl roller body 1; The high neck portion in workpiece 6 outsides is positioned within the concave station 2; An awl volume body 1 presses down, and along with the carrying out of whole collars process, can roll out the annular forging piece that the outside has hub.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
