Abstract
The utility model discloses a kind of mould structure for the production of train driven gear, it comprises core roller and main mould, forging is arranged between described core roller and described main mould, described core roller middle part is the cylindrical section of cylindrical structure, on described cylindrical section, be provided with He Xia convex shoulder, convex shoulder, between described upper convex shoulder and described lower convex shoulder, form groove, the lower surface of described upper convex shoulder is inclined upwardly, the upper surface of described lower convex shoulder is inclined upwardly, the side of described upper convex shoulder is outward-dipping from top to bottom, the side of described lower convex shoulder is outward-dipping from top to bottom, the side of described main mould is vertical plane.The train driven gear forging piece that the Mould Machining providing by the utility model goes out, more approaches the shape of product, the use of having saved material, the cutting output of following process is little, and processing cost is low, because of forging surplus little, for subsequent heat treatment, get ready, guaranteed the quality and performance of product.
Description
Technical field
The utility model belongs to mould for forging technical field, is specifically related to a kind of mould structure for the production of train driven gear.
Background technology
Train driven gear forging piece shape of product is complicated, and internal-and external diameter all has shape, and asymmetric, not easy-formation.At present, mostly traditional train driven gear forging piece processing mode is first with mould for forging, to be processed into the forging that cross section is rectangular configuration, and then carry out fine finishining after forging being cut into the shape that approaches product design, this mode exists that chipping allowance is large, waste material, shortcoming that processing cost is high.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, provides that a kind of chipping allowance is little, stable performance, material-saving and the low mould structure for the production of train driven gear of processing cost.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of mould structure for the production of train driven gear of the utility model, it comprises core roller and main mould, forging is arranged between described core roller and described main mould, described core roller middle part is the cylindrical section of cylindrical structure, on described cylindrical section, be provided with He Xia convex shoulder, convex shoulder, between described upper convex shoulder and described lower convex shoulder, form groove, 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 upper convex shoulder is outward-dipping from top to bottom, the side of described lower convex shoulder is outward-dipping from top to bottom, the side of described main mould is vertical plane.
Further, the lower surface of described upper convex shoulder is inclined upwardly 42 °～48 °, downward-sloping 28 °～32 ° of the upper surface of described lower convex shoulder.
Further, outward-dipping 1 °～5 ° from top to bottom of the sides of described upper convex shoulder, and outward-dipping 1 °～5 ° from top to bottom of the sides of described lower convex shoulder.
Further, the circular arc that the joint of the Yu Qi lower surface, side of described upper convex shoulder is R50.
Further, the circular arc that the joint of the Yu Qi upper surface, side of described lower convex shoulder is R40.
The beneficial effect that the utility model reaches is:
The train driven gear forging piece that the Mould Machining providing by the utility model goes out, more approaches the shape of product, and the use of having saved material is saved raw material approximately 10～15% than conventional rectangle forging, and the cutting output of following process is little, and processing cost is low; Because forging surplus is little, for subsequent heat treatment, get ready, guaranteed the quality and performance of product.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of mould structure for the production of train driven gear of the utility model, it comprises core roller 1 and main mould 2, forging 3 is arranged between core roller 1 and main mould 2, the cylindrical section 4 that core roller 1 middle part is cylindrical structure, on cylindrical section 4, be provided with convex shoulder 5 and lower convex shoulder 6, between upper convex shoulder 5 and lower convex shoulder 6, form groove 7, the lower surface of upper convex shoulder 5 is inclined upwardly, the upper surface of lower convex shoulder 6 is downward-sloping, the side of upper convex shoulder 5 is outward-dipping from top to bottom, the side of lower convex shoulder 6 is outward-dipping from top to bottom, the side of main mould 2 is vertical plane.
Wherein:
The lower surface of upper convex shoulder 5 is inclined upwardly 45 °, downward-sloping 30 ° of the upper surface of lower convex shoulder 6;
Outward-dipping 2 ° from top to bottom of the sides of upper convex shoulder 5, and outward-dipping 2 ° from top to bottom of the sides of lower convex shoulder 6;
The circular arc that the joint of the Yu Qi lower surface, side of upper convex shoulder 5 is R50;
The circular arc that the joint of the Yu Qi upper surface, side of lower convex shoulder 6 is R40.
The train driven gear forging piece that the Mould Machining providing by the utility model goes out, more approaches the shape of product, and the use of having saved material is saved raw material approximately 10～15% than conventional rectangle forging, and the cutting output of following process is little, and processing cost is low; Because forging surplus is little, for subsequent heat treatment, get ready, guaranteed the quality and performance of product.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.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.
