Description
Technical field
The invention belongs to mould for forging technical field, be specifically related to a kind of mould structure for the production of large-scale mine wheel seat ring.
Background technology
Large-scale mine wheel seat ring forging products is complex-shaped, and product parts inner diametric step depth is very large, and for as far as possible close to part, reduce forging surplus, the depth of forging also wants large, and it is large to roll over ring difficulty, the press power that needs are larger like this, and needs preformed.At present, mostly traditional large-scale mine wheel seat ring forging process mode is first to be processed into mould for forging the forging that cross section is rectangular configuration, and then carry out fine finishining after the shape being cut into by forging close to product design, this mode exists that chipping allowance is large, waste material, shortcoming that processing cost is high.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provide that a kind of chipping allowance is little, stable performance, material-saving and the low mould structure for the production of large-scale mine wheel seat ring of processing cost.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of mould structure for the production of large-scale mine wheel seat ring of the present invention, it comprises core roller and main mould, forging is arranged between described core roller and described main mould, it is the cylindrical section of cylindrical structure in the middle part of described core roller, described cylindrical section is provided with convex shoulder and lower convex shoulder, groove is formed between described upper convex shoulder and described lower convex shoulder, the upper surface of described upper convex shoulder is downward-sloping, the lower surface of described upper convex shoulder is inclined upwardly, the upper surface of described lower convex shoulder is downward-sloping, the side of described lower convex shoulder is outward-dipping from top to bottom, the side of described main mould is vertical plane.
Further, swing to control forging, also be provided with and embrace roller arrangement, described armful of roller arrangement comprises embraces roll shaft, described armful of roll shaft one end is fixed on embraces on roll shaft holder, the described armful of roll shaft other end is fixedly connected with embraces roller, and described armful of roller top is provided with boss, and described armful of roll shaft can move up and down relative to described armful of roller bearing holder.
Further, downward-sloping 42 ° ~ 48 ° of the upper surface of described upper convex shoulder.
Further, the lower surface of described upper convex shoulder is inclined upwardly 22 ° ~ 28 °, downward-sloping 6 ° ~ 8 ° of the upper surface of described lower convex shoulder, outward-dipping 1 ° ~ 5 ° from top to bottom, the side of described lower convex shoulder.
Further, described upper convex shoulder and described cylindrical section joint are the circular arc of R50.
Further, the side of described upper convex shoulder and the joint of lower surface are the circular arc of R30.
Further, the side of described lower convex shoulder and the joint of lower surface are the circular arc of R20.
The present invention is operationally:
Main mould rotates, and utilizes the driven rotation of frictional force drives forging, and core roller does straight-line feed motion while driven rotation.Under the acting in conjunction of main mould, core roller, forging produces continuous local plastic distortion.Forging is in rolled process, and because of its local pressure, contact area is asymmetric, easily produces swing.For controlling the dancing in the forging operation of rolling, setting up and embracing roller arrangement.Embrace roller to contact with forging, driven rotation under the effect of frictional force.Diameter of forgings expands, and embraces roller and does setback.
Wherein, upper convex shoulder and the cylindrical section of described core roller form the first station, and upper convex shoulder and the lower convex shoulder of described core roller form the second station, operationally, first forging is processed as the first station, when forging rolles over ring to required internal diameter, then dropped to the second station and carry out reaming.
The beneficial effect that the present invention reaches is:
The large-scale mine wheel seat ring forging gone out by Mould Machining provided by the invention, forge monolateral surplus and be about 9-10mm, closer to the shape of product, save the use of material, raw material about 20 ~ 30% are saved than conventional rectangular forging, ratio than ever internal diameter has shape conservation 7%, and the cutting output of following process is little, and processing cost is low; Because forging surplus is little, for subsequent heat treatment is got ready, ensure that the quality and performance of product; Boss is provided with owing to embracing roller arrangement, boss serves the effect supporting forging, therefore, achieves and a core roller can be realized two station designs, save mould replacing time at least 1 hour, also save die cost, realize two stations and roll over ring, the secondary avoiding product melts down, reduce scaling loss 5%, simultaneously need not more mold exchange, directly can reach a pyrogene type, save the energy.
