Abstract
The utility model discloses a support forging jumping -up mould structure, wherein, comprises an upper die and a lower die, go up the mould with the installation closed relatively of lower mould opening, wherein, it has the cavity to go up mould inner wall department, the utility model discloses a support forging jumping -up mould structure produces a cavity in the place that the blanking groove corresponds forging installation base position to hold more metals, thereby guarantee that thereby the place that has abundant material to gather the die cavity installation base is full of the die cavity, avoid forming folding defect, improved the qualification rate of forging.
Description
Technical field
The utility model relates to a kind of mould structure of support forge piece of excavator transmission mechanism, especially for a kind of support forge piece heading die structure.
Background technology
Support forge piece on excavator transmission mechanism is a kind of forging of high complexity coefficient, as shown in Figure 1 and Figure 2, it comprises a base plate 1 and a vertical plate part 2, and vertical plate part 2 is perpendicular with base plate 1, vertical plate part 2 is provided with gross weight 20, and gross weight is by the excision of follow-up punching operation.Place near vertical plate part 2 in base plate 1 has one for being arranged on the boss B on excavator transmission mechanism.This forging die joint in a mold is generally in the position shown in A-A line in Fig. 2.This forging is deteriorated large due to cross section, and the metal that base plate 1 place needs is few and metal that is that need at vertical plate part 2 is many, and generally need first to carry out base, object is that the needs of metal material by forging are distributed.Preforming is generally carried out in base die cavity, to reduce the requirement to workman's technical merit.Base die cavity is generally designed to the shape of Fig. 3, and combined by patrix 11 and counterdie 12, patrix comprises upper cavity 111, and counterdie comprises lower mode cavity 121, and the cavity of the centre of upper die and lower die composition is revolving body.This structure fills out the demand of punching at the installation base B place more metals of needs owing to not considering, cause the metal at installation base B place not enough, often need the metal flow in other place to come to supplement, therefore often form fold defect.
Utility model content
Above-mentionedly need the metal flow in other place to come to supplement when forging to solve, therefore often form the problem of fold defect, the utility model provides a kind of support forge piece heading die structure.
For achieving the above object, the utility model provides a kind of support forge piece heading die structure, wherein,
Comprise upper die and lower die, the closed installation relative to described lower die open of described patrix, wherein,
Described patrix inwall place has cavity.
Above-mentioned support forge piece heading die structure, wherein, described patrix has upper cavity.
Above-mentioned support forge piece heading die structure, wherein, described counterdie has lower mode cavity.
Above-mentioned support forge piece heading die structure, wherein, the wall thickness of described patrix is slightly larger than the wall thickness of described counterdie.
Above-mentioned support forge piece heading die structure, wherein, described cavity is positioned at described patrix inwall tip position.
Above-mentioned support forge piece heading die structure, wherein, described patrix inwall tip position place arc transition.
The beneficial effects of the utility model are:
Support forge piece heading die structure of the present utility model produces a cavity in the place of the corresponding forging installation base position of blanking groove, to hold more metal, thus ensure abundant material and gather the place of die cavity installation base thus be full of die cavity, avoid the formation of fold defect, improve the qualification rate of forging.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the structural representation of support forge piece in prior art;
Fig. 2 is the side view of support forge piece in prior art;
Fig. 3 is the structural representation of the mould making support forge piece in prior art;
Fig. 4 is the structural representation of support forge piece heading die structure of the present utility model.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Embodiment
Shown in Figure 4, a kind of support forge piece heading die structure of the present utility model, wherein,
Comprise patrix 11 and counterdie 12, patrix 11 closed installation relative to counterdie 12 opening, wherein,
Patrix 11 inwall place has cavity 13.
The utility model also has following embodiment on the basis of the above, please continue shown in Figure 4,
In further embodiment of the present utility model, patrix 11 has upper cavity 111, and counterdie 12 has lower mode cavity 121, and upper cavity 111 and lower mode cavity 121 are two independent moulds respectively, and the opening of two moulds can be relatively closed, forms turned cavities between two die cavitys.
In further embodiment of the present utility model, according to the structure of forging in Fig. 1, the wall thickness of patrix 11 is slightly larger than the wall thickness of counterdie 12, and cavity 13 is positioned at patrix 11 inwall tip position, patrix 11 inwall tip position place arc transition.
User can further be familiar with characteristic of the present utility model and function according to following explanation,
The utility model provides a kind of feature of support forge piece heading die structure to be, and patrix 11 inwall tip position place offers cavity 13 structure, cavity 13 can make base die cavity hold more metal at installation base B (as depicted in figs. 1 and 2) place, ensures that installation base B can filling be full can't form fold defect.
A cavity B ' is produced in the place at the corresponding forging installation base B place of blanking groove, to hold more metal, thus ensure abundant material and gather the place of die cavity installation base B thus be full of die cavity, avoid the formation of fold defect, improve the qualification rate of forging.
The foregoing is only the utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilization the utility model descriptions and diagramatic content and apparent change obtain in protection domain of the present utility model.
