For reaching this purpose, the utility model by the following technical solutions:
A kind of deformed ring forging mould, comprise core roller and xenotype mold, wherein, the center of described xenotype mold arranges porose, periphery is provided with spill with definite shape/protruding circulus, described special-shaped mould is located on the core roller by the borehole jack that arranges on it, and described special-shaped mould becomes removable syndeton with the core roller.
As a kind of preferred, the periphery of described xenotype mold is provided with a fluted body circulus.
Preferred as another, be tight fit between described special-shaped mould and core roller.
As preferably, an end of described special-shaped mould is provided with pad, and an end of described pad is provided with retaining spare, and described retaining spare is fixedly connected with the core roller by securing member.
As preferably, described securing member is that screw or other can play the structure of fixation.
As preferably, described securing member is 8, and correspondence is installed on four direction in twos.
Further, described deformed ring forging is large-sized special-shaped ring forging.
The beneficial effects of the utility model are: the utility model is by being connected special-shaped mould with the core roller is removable, for convenience detach, can design corresponding xenotype mold according to the structure difference of processing annular forging piece, and need not to change the miscellaneous parts such as core roller, versatility and interchangeability are strong, effectively reduce the mould input cost; Simultaneously, the periphery of xenotype mold arranges the annular special groove structure, can largely reduce the raw material input cost; And this is simple in structure, and is easy to operate, increases work efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of deformed ring forging mould comprises core roller 1 and xenotype mold 5.The center of xenotype mold 5 arranges porose 51, periphery is provided with spill with definite shape/protruding circulus 52, special-shaped mould 5 is sheathed on core roller 1 in friction tight mode by the hole 51 that arranges on it, and 1 one-tenth removable syndeton of special-shaped mould 5 and core roller; One end of special-shaped mould 5 is provided with pad 4, and an end of pad 4 is provided with retaining spare 2, and retaining spare 2 is fixedly connected with core roller 1 by securing member 3.
As a kind of optimal way of the present embodiment, described securing member 3 can play the structure of fixation for screw or other, and described securing member is 8, and correspondence is installed on four direction in twos.
In the present embodiment, deformed ring forging is large-sized special-shaped ring forging.
In the present embodiment, be that example illustrates xenotype mold structure of the present utility model for the shaped rings part shown in Fig. 2.As Fig. 2, there is a shaped rings projection 61 inside of this shaped rings part 6, and should projection 61 be not to be symmetrical arranged.If use traditional straight-flanked ring design to add the cost of raw material that trade union increases 20-30%, so can adopt the shaped rings structure that the utility model proposes processes, according to the rolling deflection of forging and the height of projection, suitably add surplus, and with boss 61 apart near one the placing facing up of end face; Be the projection 61 in the above-mentioned shaped rings 6 of correspondence, the periphery of xenotype mold 5 is provided with a fluted body circulus 52, in rolling over the ring process, the blank extruding is entered the projection 61 that this groove 52 forms inside parts.Structure such as Fig. 3 of drawing thus xenotype mold 5 show, wherein, the parameters such as the degree of depth of groove 52 and residing position height can be adjusted according to actual parts.In addition, special-shaped mould 5 shown in Figure 3 is provided with corresponding chamfering in the edge of groove 52, corresponding, can reserve certain allowance on forging after rolling, in order to following process.
Be forging 7 after the processing of above-mentioned special-shaped mould rolling as Fig. 4, corresponding, in the edge of the projection of forging 7, certain chamfering surplus is arranged.After rolling, forging 7 is carried out other machinings again, remove the surplus that rolling processing reserves, will obtain part shown in Figure 2, this processing mode can reach the saving material, reduces the purpose of the workload of other machinings.
The forging making of the present embodiment is described below in conjunction with the course of work of Ring Rolling Machine.
King roller in Ring Rolling Machine rotates and the straight-line feed motion, is the drive roll of ring rolling.The core roller is driven voller, does the rolling motion of driven rotation under the drive of king roller.As shown in Figure 5, during Ring Rolling Machine work, first the core roller is fallen back on upper limit, special-shaped mould 5 be placed on work top and center and core roller center are placed, more prefabricated ring base 9 being enclosed within the outer shroud of special-shaped mould 5, at this moment, the core roller enters into interstitial hole 51 places of xenotype mold 5 downwards, and by the location of pad 4 with retaining spare 2, closely be fixed on the core roller, then Ring Rolling Machine is rolled over ring-rolling.In the operation of rolling, core roller 1 is close to king roller 8 gradually, by the roll-force effect of king roller 8 with core roller 1, ring base 9 is subject to radial and axial spreading distortion, progresses into when radially growing up in the groove ring 52 of xenotype mold 5, and its radial end face produces local plastic deformation, diameter constantly enlarges, finally obtain the geomery that designs, at this moment, what obtain is forging structure shown in Figure 4.After rolling over the loops bundle, the core roller is upwards pulled out special-shaped mould 5, and special-shaped mould and product can lightly take out.
This special-shaped mould structure, can differently according to product structure change, improve the operating efficiency nearly 15% of rolling deformed ring forging, and only change special-shaped mould and change the groove/land circulus, can realize easily having the production of the series of products of similar special-shaped forge parts, reduce mould input cost nearly 77%.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
