Abstract
The utility model discloses a kind of valve cover forging molding blank frock, it is characterised in that：The frock includes pre-upset mould and mould, the mould of pre-upsetting is arranged to stair-stepping through hole, its big end a diameter of d upward, the mould is arranged to stepped throughhole, its big end upward a diameter of D, its small end diameter and the outside diameter of the mould of pre-upsetting mutually are all d down, and insert is set at the shaft shoulder of the small end.The beneficial effects of the utility model are：Using the process that the mould is forged, can by bonnet it is cylindrical on groove forge, so that forging shape is closer to finished form, material usage averagely reduces by 20%, greatly reduce cost of manufacture, with considerable economic benefit, while reducing follow-up mach workload, production efficiency is effectively increased.
Description
Technical field
The utility model is related to cylinder class ring forging stock technical field, more particularly, to a kind of valve cover forging molding blank
Frock.
Background technology
At present, in petrochemical system, valve is the important composition part of pipe-line system, and valve mass is related to whole system
The safety of system, valve will cause medium to reveal once breaking down, and cause environmental pollution or even cause fire, blast etc. pernicious
Security incident.Therefore it is especially high for the quality requirement of valve, forging valve with it dense structure, performance safety it is reliable and
Progressively occupy the bigger market share.Bonnet is the important feature part of valve, and being structurally characterized in that for bonnet is cylindrical fluted, recessed
From 40mm--150mm, general at present using the shaping of open die forging square-section, groove cannot be forged well width, cause material
Amount ratio is larger, not only increases production cost, and extend the following process time.
The content of the invention
The purpose of this utility model is to overcome shortcoming present in prior art, there is provided a kind of valve cover forging molding hair
Base frock, the frock saves material significantly, reduces cost, has saved the time of machining, and the technical scheme of use is：One
Plant valve cover forging molding blank frock, it is characterised in that：The frock includes pre-upset mould and mould, described to pre-upset
Mould is arranged to stair-stepping through hole, and its big end a diameter of d upward, the mould is arranged to stepped throughhole, its big end
Diameter is mutually all d with the outside diameter of the mould of pre-upsetting down for a diameter of D, its small end upward, and in the axle of the small end
Insert is set at shoulder.
Technical characteristic of the present utility model also has：The endoporus of the mould of pre-upsetting is provided with pattern draft.
Technical characteristic of the present utility model also has：The endoporus of the mould is provided with pattern draft.
Technical characteristic of the present utility model also has：The insert is combined by 3 pieces of eccentric circular rings.
Technical characteristic of the present utility model also has：It is complete circle after the insert combination, the external diameter of the annulus compares institute
State the small 1-2mm in mould inner chamber, endoporus and the valve body blank groove diameter d0It is equal.
The beneficial effect of this programme can be learnt according to the narration to such scheme, using the process of the forging dies, energy
By bonnet it is cylindrical on groove forge so that closer to finished form, material usage averagely reduces by 20% to forging shape, drops significantly
Low cost of manufacture, with considerable economic benefit, while reducing follow-up mach workload, effectively increases life
Produce efficiency.With forging stock quality is high, the advantage of good stability, low cost.
Brief description of the drawings
Fig. 1 is bonnet finished product,
Fig. 2 is open die forging bonnet blank,
Fig. 3 is blank after being forged using the frock,
Fig. 4 is the utility model heading die structural representation,
Fig. 5 is the utility model forming die structure schematic diagram,
Wherein 1 is mould of pre-upsetting, and 2 is insert, and 3 is mould.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is illustrated.The utility model discloses one kind
Valve cover forging molding blank frock, it is characterised in that：The frock includes pre-upset mould 1 and mould 3, described to pre-upset
The tool of mould 1 is arranged to stair-stepping through hole, and its big end a diameter of d upward, the mould 3 is arranged to stepped throughhole, and its is big
Diameter is mutually all d with the outside diameter for pre-upsetting mould 1 down to hold a diameter of D, its small end upward, and in the small end
Insert is set at the shaft shoulder.The blank shape forged by the frock is closer to product, has saved raw material.
The endoporus for pre-upsetting mould 1 is provided with pattern draft.So, blank forging is completed, and is easy to blank smoothly to go out
Mould.
The endoporus of the mould 3 is provided with pattern draft.Purpose is equally that blank forging is completed, and is easy to blank smooth
Depanning.
The insert 2 is combined by 3 pieces of eccentric circular rings.Insert 2 is placed in the inner chamber of mould 3, with the common structure of mould 3
Into die cavity.
The insert 2 combine after be complete circle, the external diameter of the annulus than the small 1-2mm of intracoelomic cavity of the mould 3,
Endoporus and the valve body blank groove diameter d0It is equal.
Operation principle, blank jumping-up small end d first in mould 1 of pre-upsetting, is then put into shaping by the blank after jumping-up
In mould 3, three ingredient inserts 2 are put into mould afterwards, upsetting upset D.After blank squeezes into mould completely, endoporus is rushed, it
Afterwards by die flip, bonnet blank and ingredient insert after shaping deviate from mould together, finally wash out blanking inner hole gross weight, hair
Base forging is completed, for ease of the smooth depanning of blank, it is noted that making pattern draft in shown position during Mold Making.
Certainly, described above is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
Change, remodeling, addition or replacement that the those of ordinary skill in art field is made in essential scope of the present utility model, also belong to
In protection domain of the present utility model.
