Description
Technical field
The utility model relates to mould applications more particularly to a kind of mould structures for promoting triple-valve body forging quality.
Background technique
As shown in Fig. 2, the shape of the flowing of metal and forging, blank shape and size, mode of texturing, change in multi-ram forging
Shape speed, deformation temperature and lubricating condition have relationship.And the mobility status of metal is to forging Forming Quality, die life, power energy
Consumption has large effect.In the production process of certain high pressure valve body, always occur that flange thickness is uneven, flange fills not
Completely, the phenomenon that fillet is big, the accumulation of flange base oxide skin increases rejection rate, reduction company's benefit so as to cause that can not process
The problem of.
Utility model content
The utility model mainly solving the technical problems that provide it is a kind of promoted triple-valve body forging quality mould structure,
It without changing technique, is improved, can be got a desired effect by simple mould structure.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of promotion triple valve
The mould structure of body forging quality, including the accumulation of upper mold die cavity, lower die die cavity, not full Rouno Cormer Pregrinding Wheel ectype chamber, oxide are different
Joint match, the not full Rouno Cormer Pregrinding Wheel ectype chamber are in up and down for normal type chamber, radial concave surface, the upper mold die cavity and lower die die cavity
Now it is present in upper mold cavity surface for inverted right-angle structure, the right angle knot set that is positive is presented in the oxide accumulation ectype chamber
Structure is present in lower die cavity surface, and the not full Rouno Cormer Pregrinding Wheel ectype chamber is provided with radial concave surface, keeps not full Rouno Cormer Pregrinding Wheel different
For the angle of normal type chamber less than 90 degree, the oxide accumulation ectype chamber is provided with dreg collecting slot pit, keeps oxide accumulation abnormal
The angle of type chamber is less than 90 degree.
The beneficial effects of the utility model are: a kind of mold for promoting triple-valve body forging quality provided by the utility model
Structure is improved without changing technique by simple mould structure, can be got a desired effect.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is a kind of knot of a preferred embodiment of the mould structure for promoting triple-valve body forging quality of the utility model
Composition；
Fig. 2 is an a kind of preferred embodiment background of the mould structure for promoting triple-valve body forging quality of the utility model
The structure chart of technology.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
As shown in Figs. 1-2, the utility model embodiment includes:
A kind of mould structure promoting triple-valve body forging quality, including upper mold die cavity 1, lower die die cavity 2, not full great circle
Angle ectype chamber 3, oxide accumulation ectype chamber 4, radial concave surface 5, dreg collecting slot pit 6, the upper mold die cavity 1 and lower die die cavity
About 2 joint matchs, the not full Rouno Cormer Pregrinding Wheel ectype chamber 3 are rendered as inverted right-angle structure and are present in 1 table of upper mold die cavity
Face, the oxide accumulation ectype chamber 4 is presented the right-angle structure set that is positive and is present in 2 surface of lower die die cavity, described not full
Rouno Cormer Pregrinding Wheel ectype chamber 3 is provided with radial concave surface 5, makes the angle of not full Rouno Cormer Pregrinding Wheel ectype chamber 3 less than 90 degree, the oxidation
Object accumulation ectype chamber 4 is provided with dreg collecting slot pit 6, makes the angle of oxide accumulation ectype chamber 4 less than 90 degree.
Easily there is uneven flange thickness as shown in Figure 2, the not full Rouno Cormer Pregrinding Wheel of flange and flange bottom in high pressure valve body when producing
Accumulate the phenomenon that oxide in portion.It finds that the flow resistance expected when squeezing flange is big because of the uneven of blank distribution through analysis, becomes
Shape drag is big, so there is phenomenon in uneven thickness, and because flange Rouno Cormer Pregrinding Wheel is last molding position, when blank circulates
Resistance can reduce the fillibility of metal so as to cause Rouno Cormer Pregrinding Wheel phenomenon when big；When extrusion deformation, the oxide skin meeting that falls off on blank
The phenomenon that falling into lower mode cavity, be pushed at oxide accumulation then as the blank of deformation, therefore forming oxide accumulation.
Therefore increasing the mold cavity size at 5 reduces the uniform fillet of flange thickness to reduce the flow resistance of metal；
Pit (dreg collecting slot) is processed at 6, concentrates oxide skin slag all here, reduces pit caused by oxide skin on flange.
In conclusion the utility model provides a kind of mould structure for promoting triple-valve body forging quality, without change
Technique is improved by simple mould structure, can be got a desired effect.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
