Abstract
The invention discloses a shaft sleeve forging die structure which comprises a core roller and a main die. A forging is arranged between the core roller and the main die. The shaft sleeve forging die structure is characterized in that a convex shoulder portion protruding outwards is arranged in the middle of the core roller, a forming groove is formed in the main die, a step face is arranged in the forming groove, and a side face of the convex shoulder portion inclines towards the inner side by 1-3 degrees. The forging more similar with a product in shape is processed through the die structure, so that cutting allowance of subsequent processing is small, materials are saved, and processing cost is low; a certain calendering space is reserved for forging processing by the die, so that quality and performance of the product are guaranteed.
Description
Technical field
The invention belongs to the mould for forging technology, relate in particular to a kind of axle sleeve mould for forging structure.
Background technology
At present, mostly traditional axle sleeve forging process 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 to the shape that approaches product design, this mode exists that chipping allowance is large, waste material, shortcoming that processing cost is high.
Summary of the invention
The object of the present invention is to provide a kind of axle sleeve mould for forging structure, it has material-saving and the low characteristics of processing cost, the problems referred to above that exist to solve prior art bottom bracket axle forging process.
For reaching this purpose, the present invention by the following technical solutions:
A kind of axle sleeve mould for forging structure, it comprises core roller and main mould, forging is arranged between core roller and main mould, wherein, the centre of described core roller is provided with the convex shoulder of outwardly convex, offer forming tank on described main mould, be provided with a step surface in described forming tank, the side of described convex shoulder tilts 1 °～3 ° to the inside.
Especially, the circular arc that the end face turning contacted with forging on described convex shoulder is R30.
Especially, the two ends of described forming tank and the joint of main mould are respectively arranged with first and second arc section, and the corner of described step surface is provided with the three-arc section.
Especially, the circular arc that described the first arc section is R15, the circular arc that described the second arc section is R40, the circular arc that described three-arc section is R15.
Beneficial effect of the present invention is, compared with prior art described axle sleeve mould for forging structure processes the forging that more approaches shape of product by mould structure, the chipping allowance of following process is little, save material, processing cost is low, mould is that forging process leaves certain calendering space simultaneously, has guaranteed the quality and performance of product.
The accompanying drawing explanation
Fig. 1 is the structural representation of the axle sleeve mould for forging structure that provides of the specific embodiment of the invention 1;
Fig. 2 is the profile of the main mould of the axle sleeve mould for forging structure that provides of the specific embodiment of the invention 1.
