Abstract
The utility model discloses a mould for producing an excavator rotary supporting seat ring forge piece. The mould comprises a core roller and a master mould body, the forge piece is arranged between the core roller and the master mould body, the mould is characterized in that a molded groove is formed in the master mould body, a step face is arranged in the molded groove, two openings of the molded groove are of an arc structure, and the bent position of the step face is of an arc structure. The forge piece closer to the shape of a product is processed by the mould for producing the excavator rotary supporting seat ring forge piece through a mould structure, the chipping allowance of subsequent processing is small, materials are saved, processing cost is low, meanwhile, certain rolling space is reserved for forge piece processing by the mould, and the quality and performance of the product are guaranteed.
Description
Technical field
The utility model belongs to mould for forging technology, relates in particular to a kind of mould that supports seat ring forging for the production of digger revolving.
Background technology
At present, mostly the processing mode that traditional digger revolving supports seat ring 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 purpose of this utility model is to provide a kind of mould that supports seat ring forging for the production of digger revolving, and it has material-saving and the low feature of processing cost, to solve digger revolving in prior art, supports the problems referred to above that seat ring forging process exists.
For reaching this object, the utility model by the following technical solutions:
A kind of mould that supports seat ring forging for the production of digger revolving, it comprises core roller and main mould, forging is arranged between core roller and main mould, wherein, on described main mould, offer forming tank, in described forming tank, be provided with a step surface, two opening parts of described forming tank are arc structure, and the bending part of described step surface is arc structure.
Especially, the downside of described forming tank is the inclined-plane of outward-dipping 8 °～10 °.
Especially, the circular arc that upper shed place of described forming tank is R25, the circular arc that its lower opening is R20, the circular arc that the bending part of described step surface is R40.
The beneficial effects of the utility model are, compared with prior art the described mould for the production of digger revolving support seat ring forging 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.
Accompanying drawing explanation
Fig. 1 be the utility model specific embodiment 1 provide for the production of digger revolving, support the structural representation of the mould of seat ring forging;
Fig. 2 be the utility model specific embodiment 1 provide for the production of digger revolving, support the profile of main mould of the mould of seat ring forging.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Fig. 1, in the present embodiment, a kind of mould for the production of digger revolving support seat ring forging comprises core roller 1 and main mould 2, forging 3 is arranged between core roller 1 and main mould 2, on described main mould 2, offer forming tank 4, in described forming tank 4, be provided with a step surface 5, and the downside of described forming tank 4 is the inclined-plane of outward-dipping 9 °.In addition, the circular arc that upper shed place of described forming tank 4 is R25, the circular arc that its lower opening is R20, the circular arc that the bending part of described step surface 5 is R40.
The above-mentioned mould for the production of digger revolving support seat ring forging is not only saved material, and processing cost is low, and mould is that forging process leaves certain calendering space simultaneously, has guaranteed the quality and performance of product.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
