Abstract
The invention discloses a kind of axle sleeve forging piece molding die, it includes die ontology, centre bore is offered at the center of the die ontology, wherein, the die ontology is disposed with the first cylindrical section, second cylindrical section, 3rd cylindrical section and the 4th cylindrical section, first cylindrical section is equal with the external diameter of the 4th cylindrical section, the external diameter of second cylindrical section is less than the external diameter of the first cylindrical section, the external diameter of 3rd cylindrical section is less than the external diameter of the second cylindrical section, at the bottom surface outer rim of first cylindrical section, at the bottom surface outer rim of second cylindrical section, arc chord angle is disposed as at the top surface outer rim of 4th cylindrical section.Above-mentioned axle sleeve forging piece molding die can process the forging closer to shape of product, and the chipping allowance of following process is small, save material, and processing cost is low, while mould is that forging process leaves certain calendering space, ensure that the quality and performance of product.
Description
Technical field
The present invention relates to a kind of mould for forging, more particularly, to a kind of axle sleeve forging piece molding die.
Background technology
At present, existing axle sleeve forging process mode is mostly first to be processed into rectangular cross-section structure with mould for forging
Forging, then forging is cut into close to after the shape of product design again and finished, it is clear that it is this plus
The shortcomings that big chipping allowance, waste of materials, high processing costs be present in work mode.
The content of the invention
It is an object of the invention to provide a kind of axle sleeve forging piece molding die, it has, and chipping allowance is small, material-saving
The characteristics of low with processing cost, existing above mentioned problem during solving prior art bottom bracket axle forging process.
To use following technical scheme up to this purpose, the present invention：
A kind of axle sleeve forging piece molding die, it includes die ontology, offered at the center of the die ontology
Centre bore, wherein, the die ontology is disposed with the first cylindrical section, the second cylindrical section, the 3rd cylinder
Section and the 4th cylindrical section, first cylindrical section is equal with the external diameter of the 4th cylindrical section, second circle
The external diameter of shell of column is less than the external diameter of the first cylindrical section, and the external diameter of the 3rd cylindrical section is less than the second cylindrical section
External diameter, at the bottom surface outer rim of first cylindrical section, at the bottom surface outer rim of the second cylindrical section, the 4th circle
Arc chord angle is disposed as at the top surface outer rim of shell of column.
Especially, the length of first cylindrical section and the equal length of the 3rd cylindrical section, second cylinder
The length of section and the equal length of the 4th cylindrical section, and the length of first cylindrical section is more than the second cylindrical section
Length.
Especially, used at the bottom surface outer rim of first cylindrical section and at the bottom surface outer rim of the first cylindrical section
R15 circular arc, R40 circular arc is used at the top surface outer rim of the 4th cylindrical section.
Especially, the sidewall symmetry of the die ontology is provided with two fins.
Especially, several screw threads for being used for fixing mould body are offered on the one side of the die ontology
Hole.
Beneficial effects of the present invention are that the axle sleeve forging piece molding die can process compared with prior art
Closer to the forging of shape of product, the chipping allowance of following process is small, saves material, processing cost is low, together
When mould be forging process leave certain calendering space, ensure that the quality and performance of product.
Brief description of the drawings
Fig. 1 is the structural representation for the axle sleeve forging piece molding die that the specific embodiment of the invention 1 provides.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1, Fig. 1 is the axle sleeve forging piece molding die that the specific embodiment of the invention 1 provides

In the present embodiment, a kind of axle sleeve forging piece molding die includes die ontology 1, in the die ontology 1
Offer centre bore 2 at the heart, the die ontology 1 be disposed with the first cylindrical section 3, the second cylindrical section 4,
3rd cylindrical section 5 and the 4th cylindrical section 6, the external diameter phase of first cylindrical section 3 and the 4th cylindrical section 4
External diameter Deng, second cylindrical section 4 is less than the external diameter of the first cylindrical section 3, the 3rd cylindrical section 5
External diameter is less than the external diameter of the second cylindrical section 4, the length of first cylindrical section 3 and the length of the 3rd cylindrical section 5
Spend equal, the length of second cylindrical section 4 and the equal length of the 4th cylindrical section 6, and first circle
The length of shell of column 3 is more than the length of the second cylindrical section 4.
R15 is used at the bottom surface outer rim of first cylindrical section 3 and at the bottom surface outer rim of the second cylindrical section 4
Circular arc, R40 circular arc is used at the top surface outer rim of the 4th cylindrical section 6.
The sidewall symmetry of the die ontology 1 is provided with two fins 7, and the one side of the die ontology 1
On offer several be used for fixing mould body screwed hole 8.
Above example is to elaborate the general principle and characteristic of the present invention, and the present invention is not limited by above-mentioned example
System, without departing from the spirit and scope of the present invention, the present invention also have various change and change, these
Changes and modifications all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended power
Sharp claim and its equivalent thereof.
