Abstract
The invention discloses a kind of mould structure for producing agricultural equipment Diesel engine bearing outer ring, it includes core roller and main mould, forging is arranged between described core roller and described main mould, it it is the cylindrical section of cylindrical structure in the middle part of described core roller, it is provided with convex shoulder on described cylindrical section, the upper surface of described convex shoulder is downward-sloping, and the lower surface of described convex shoulder is inclined upwardly；The end face of described convex shoulder is vertical plane；The side of described main mould is vertical plane.The agricultural equipment Diesel engine bearing outer ring that the mould provided by the present invention is processed, shape closer to product, convenient formation, saves the use of material, saves raw material about 10～15% than conventional rectangular forging, the cutting output of following process is little, properties of product are preferable, and processing cost is low, reduces machining procedure before a heat treatment, reduce last machining time, improve efficiency.
Description
Technical field
The invention belongs to mould for forging technical field, be specifically related to a kind of for producing agricultural equipment Diesel engine bearing outer ring
Mould structure.
Background technology
Agricultural equipment Diesel engine is complicated with bearing outer ring shape of product, and internal-and external diameter all has shape, and asymmetric, not easy-formation.Mesh
Before, traditional agricultural equipment Diesel engine bearing outer ring processing mode typically uses conventional rectangular to forge, and before carrying out heat treatment, machine adds
Work (reduces follow-up machining allowance, increase through hardening layer depth), then heat treatment, the most machining, uses material a lot, leads
Causing waste material, processing cost height, the forging price in turn resulting in race ring is the highest.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of convenient formation, material-saving and being processed into
This low mould structure for producing agricultural equipment Diesel engine bearing outer ring.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of mould structure for producing agricultural equipment Diesel engine bearing outer ring of the present invention, it includes core roller and main mould, forges
Part is arranged between described core roller and described main mould, is the cylindrical section of cylindrical structure, on described cylindrical section in the middle part of described core roller
Being provided with convex shoulder, the upper surface of described convex shoulder is downward-sloping, and the lower surface of described convex shoulder is inclined upwardly；Described convex shoulder
End face be vertical plane；The side of described main mould is vertical plane.
Further, the upper surface of described convex shoulder and the circular arc that joint is R18 of described end face.
Further, the lower surface of described convex shoulder and the circular arc that joint is R20 of described end face.
The present invention is reached to provide the benefit that:
The present invention, according to the feature of bearing outer ring, designs mould, it is achieved steel alloy non-rectangle rolles over ring.Steel alloy internal stress
Greatly, general only carbon steel and low alloy steel makes formed forgings.The present invention, according to metal fluidity and the feature of bearing outer ring, closes
Reason deisgn product die angle, forging shape and size are tried one's best close with product.The mould provided by the present invention is processed
Agricultural equipment Diesel engine bearing outer ring, closer to the shape of product, convenient formation, saves the use of material, forges than conventional rectangular
Part saves raw material about 10～15%, and the cutting output of following process is little, and properties of product are preferable, and processing cost is low, reduces once heat
Machining procedure before processing, reduces last machining time, improves efficiency.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, with the reality of the present invention
Execute example together for explaining the present invention, be not intended that limitation of the present invention.In the accompanying drawings:

As shown in Figure 1 to Figure 3, a kind of mould structure for producing agricultural equipment Diesel engine bearing outer ring of the present invention, its bag
Including core roller 1 and main mould 2, forging 3 is arranged between described core roller 1 and described main mould 2, is cylindrical structure in the middle part of described core roller 1
Cylindrical section 4, described cylindrical section 4 is provided with convex shoulder 5, the upper surface 501 of described convex shoulder 5 is downward-sloping, described convex shoulder
The lower surface 502 in portion is inclined upwardly；The end face 503 of described convex shoulder is vertical plane；The side 201 of described main mould 2 is vertical plane.
The upper surface 501 of described convex shoulder 5 and the circular arc that joint is R18 of described end face 503.
The lower surface 502 of described convex shoulder 5 and the circular arc that joint is R20 of described end face 503.
The present invention, according to the feature of bearing outer ring, designs mould, it is achieved steel alloy non-rectangle rolles over ring.Steel alloy internal stress
Greatly, general only carbon steel and low alloy steel makes formed forgings.The present invention, according to metal fluidity and the feature of bearing outer ring, closes
Reason deisgn product die angle, forging shape and size are tried one's best close with product.The mould provided by the present invention is processed
Agricultural equipment Diesel engine bearing outer ring, closer to the shape of product, convenient formation, saves the use of material, forges than conventional rectangular
Part saves raw material about 10～15%, and the cutting output of following process is little, and properties of product are preferable, and processing cost is low, reduces once heat
Machining procedure before processing, reduces last machining time, improves efficiency.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
