Embodiment：
A kind of core roller for forging valve deck forging, referring to Fig.1 comprising work department 1 and interconnecting piece 2.Interconnecting piece 2 includes
Head rod 21 and the second connecting rod 22, work department 1 are arranged between head rod 21 and the second connecting rod 22.First connects
Extension bar 21 and the second connecting rod 22 can be with the supporting shaft hole on Ring Rolling Machine（It is not shown in figure）Cooperation, turn for enabling core roller to stablize
It is dynamic.Work department 1 includes coaxially connected shaft core 11 and circular shaft section 12, and the diameter of shaft core 11 is less than the diameter of circular shaft section 12, also small
In the diameter of head rod 21.The inner ring of valve deck forging can be rolled over using shaft core 11 and circular shaft section 12 and type is made, to have
Effect avoids the waste of the lot of materials generated in later stage turning process, and having can save material, reduce production cost
Advantage.
Referring to Figures 1 and 2, head rod 21 is fixedly connected close to one end of work department 1 with shaft core 11, shaft core 11 and
It is provided with transition arc 3 between one connecting rod 21.Pass through the setting of the transition arc 3, on the one hand, increase head rod 21
Bonding strength between shaft core 11.On the other hand, valve deck forging reduces valve deck forging internal diameter and core roller during rolling over processed
Between stress so that the non-uniform phenomenon of local pressure will not occur in spreading deformation process for valve deck forging, ensure that valve
The stabilization of grain structure inside lid forging effectively increases the structural strength of valve deck forging.
With reference to Fig. 2, the radius of transition arc 3 is 5mm can make the internal diameter and core of valve deck forging during carrying out rolling
Stress between roller is uniformly distributed.When the radius of transition arc 3 is too small, the intensity of core roller can be caused to decline, make core roller breakage.
When the radius of transition arc 3 is excessive, then it can make valve deck forging that cannot be quickly molded during compacting.In the present embodiment
In, according to the size of valve deck forging, the radius of transition arc 3 is preferably 5mm.When valve deck forging and core roller coordinate, valve deck forging
Part can generate vertical load to core roller.Under the action of vertical load, valve deck forging and the stressing conditions of core roller junction can be sent out
It is raw to change, to increase the local pressure of core roller.When vertical load is applied on transition arc 3, the work in vertical direction
It firmly can uniformly disperse to surrounding, reduce the stress concentration of valve deck forging end and core roller edge, and then ensure that valve deck
Forging is not in the problem of local stress is unevenly distributed during spreading so that valve deck forging is in entire roller compaction process
In, it can remain the state of uniform force.
Referring to Fig.1, second one end of connecting rod 22 far from work department 1 is provided with truncated cone-shaped guide pad 4, truncated cone-shaped guide pad
4 have guiding role so that the second connecting rod 22 is more easy to be inserted into the supporting shaft hole on Ring Rolling Machine（It is not shown in figure）In.First
The one end of connecting rod 21 far from work department 1 is provided with round estrade section 5, and round estrade section 5 can coordinate with the supporting shaft hole on Ring Rolling Machine,
Head rod 21 is fixed.The taper of round estrade section 5 is 5-7 degree.When the taper of round estrade section 5 is 5 degree, round estrade section
5 with Ring Rolling Machine on supporting shaft hole binding face be more than 65% so that core roller can reach relatively good cooperation with supporting shaft hole.When
When the taper of round estrade section 5 is 7 degree, the binding face of the supporting shaft hole on round estrade section 5 and Ring Rolling Machine is more than 75%, in this way can be with
Core roller is set to reach better cooperation with supporting shaft hole, to ensure that core roller can stablize work.
Referring to Fig.1, the one end of round estrade section 5 far from head rod 21 is provided with locating rod 6, and the diameter of locating rod 6 is small
In round estrade section 5 close to the diameter of one end of locating rod 6.Locating rod 6 has positioning action, and round estrade section 5 is inserted into support shaft
Kong Hou, locating rod 6 can be with the positioning shaft holes in supporting shaft hole（It is not shown in figure）Cooperation so that round estrade section 5 not will produce askew
Tiltedly.The one end of locating rod 6 far from round estrade section 5 is provided with location hole 7, and location hole 7 can be with the positioning shaft in positioning shaft hole（Figure
In be not shown）Cooperation.After locating rod 6 stretches into positioning shaft hole, locating rod 6 is located between positioning shaft hole inner wall and positioning shaft,
Further ensure round estrade section 5 not will produce it is crooked, effectively increase core roller work stability.
Referring to Figure 1 and Figure 3, round estrade section 5 is provided with elastic buffering pad 8, elastic buffering pad 8 close to one end of locating rod 6
With elasticity, round estrade section 5 and the supporting shaft hole on Ring Rolling Machine are avoided（It is not shown in figure）Rigid collision occurs for bottom wall, has
Cushioning effect.Elastic buffering pad 8 is internally provided with several bulging cavitys 81 so that elastic buffering pad 8 is more soft, buffering effect
Fruit is more preferably.
Operation principle is as follows：
After installation is complete, head rod 21 and the second connecting rod 22 coordinate core roller with the supporting shaft hole on Ring Rolling Machine, from
And the rotation that core roller is stablized.
When type is made in the inner ring rolling of valve deck forging using core roller, under the action of shaft core 11 and circular shaft section 12, it can make
The diameter of the blank of valve deck forging is constantly expanded, and the geomery of design is finally obtained, and effectively avoids later stage turning process
The waste of the lot of materials of middle generation has the advantages that save material, reduces production cost.
For valve deck forging during rolling over processed, transition arc 3 reduces the stress between valve deck forging internal diameter and core roller so that
The non-uniform phenomenon of local pressure will not occur in spreading deformation process for valve deck forging, ensure that valve deck forging internal grain knot
The stabilization of structure effectively increases the structural strength of valve deck forging.
