Description
Technical field
The invention belongs to mould for forging technical field, and in particular to a kind of mould for being used to produce large-scale mine wheel seat ring
Lamps structure.
Background technology
Large-scale mine wheel is complex-shaped with seat ring forging products, and product parts inner diametric step depth is very big, is as far as possible
Close to part, forging surplus is reduced, the depth of forging is also big, and rolling ring difficulty is big, so needs larger press power, Er Qiexu
It is preforming.At present, traditional large-scale mine wheel is mostly first to be processed into section with mould for forging with seat ring forging process mode
For the forging of rectangular configuration, then forging is cut into again and finished close to after the shape of product design, this mode is deposited
Chipping allowance is big, waste of materials, the shortcoming of high processing costs.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect there is provided a kind of chipping allowance is small, performance stable, save
Material and the low mould structure for being used to produce large-scale mine wheel seat ring of processing cost.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
A kind of mould structure for being used to produce large-scale mine wheel seat ring of the present invention, it includes core roller and main mould, forging
It is arranged between the core roller and the main mould, is to be set on the cylindrical section of cylindrical structure, the cylindrical section in the middle part of the core roller
Convex shoulder and lower convex shoulder are equipped with, groove is formed between the upper convex shoulder and the lower convex shoulder, the upper convex shoulder
Upper surface is downward-sloping, and the lower surface of the upper convex shoulder is inclined upwardly, and the upper surface of the lower convex shoulder is downward-sloping, described
The side of lower convex shoulder is outward-dipping from top to bottom, and the side of the main mould is vertical plane.
Further, in order to control forging to swing, it is additionally provided with and embraces roller arrangement, described armful of roller arrangement includes embracing roll shaft, institute
State an armful roll shaft one end to be fixed in armful roll shaft fixed seat, the described armful of roll shaft other end, which is fixedly connected with, embraces a roller, at the top of described armful of roller
Be provided with boss, described armful of roll shaft can relative to described armful roll shaft fixed seat move up and down.
Further, downward-sloping 42 °~48 ° of the upper surface of the upper convex shoulder.
Further, the lower surface of the upper convex shoulder is inclined upwardly 22 °~28 °, the upper end of the lower convex shoulder towards
It is lower to tilt 6 °~8 °, outward-dipping 1 °~5 ° from top to bottom of the side of the lower convex shoulder.
Further, the upper convex shoulder and the circular arc that the cylindrical section joint is R50.
Further, the circular arc that the side of the upper convex shoulder is R30 with the joint of lower surface.
Further, the circular arc that the side of the lower convex shoulder is R20 with the joint of lower surface.
The present invention is operationally：
Main mould is rotated, and using the driven rotation of frictional force drives forging, core roller makees straight-line feed fortune while driven rotation
It is dynamic.Under main mould, the collective effect of core roller, forging produces continuous local plastic deformation.Forging is during rolled, because of it
Local pressure, contact area is asymmetric, easily produces swing.For the dancing in the control forging operation of rolling, set up and embrace roller
Device.Embrace roller to contact with forging, the driven rotation in the presence of frictional force.Diameter of forgings expands, and embraces roller and makees setback.
Wherein, the upper convex shoulder of the core roller and cylindrical section the first station of formation, the upper convex shoulder of the core roller and lower convex shoulder
Portion forms the second station, operationally, is first processed forging as the first station, when forging rolles over ring internal diameter needed for,
The second station will be fallen under it again and carries out reaming.
The beneficial effect that is reached of the present invention is：
The large-scale mine wheel seat ring forging that the mould provided by the present invention is processed, forges unilateral surplus about 9-
10mm, closer to the shape of product, saves the use of material, and raw material about 20~30% are saved than conventional rectangular forging, than
Internal diameter has shape to save raw material 7% than ever, and the cutting output of following process is small, and processing cost is low；It is follow-up because forging surplus is small
Heat treatment is got ready, it is ensured that the quality and performance of product；Boss is provided with due to embracing roller arrangement, boss serves support
The effect of forging, it is thereby achieved that a core roller can be realized that two stations are designed, saves mould replacing time at least 1 hour,
Die cost is saved, realizes that two stations roll over ring, it is to avoid the secondary of product melts down, scaling loss 5% is reduced, while without more changing the mold
Tool, can directly reach a fire shaping, save the energy.
