Description

The mould of forging elliposoidal Shell Forging Parts
Technical field
The utility model belongs to the technical field of forging in machine-building, particularly a kind of mould of forging elliposoidal Shell Forging Parts.
Background technology
In machine field, have inner chamber for inside, the classical production process of elliposoidal housing part in irregular shape be generally adopt forging solid forging mode shaping, and then by boring, the inner unnecessary surplus of turning is produced, the product that this mode is produced is cut off because of forging internal fiber direction, reduces its comprehensive mechanical property and service life; Or adopt casting straight forming, but interior tissue and mechanical property wayward, there is material structure problem pockety, cause comprehensive mechanical property not easily to meet the instructions for use of pressure vessel.
If pulsation damper typically has inner chamber, elliposoidal housing part in irregular shape, be pressure vessel one of key element, and pulsation damper is as the main pressed part of its equipment, very strict to its quality requirement, during work, pressurized is heavy and complicated, do not allow porosity defect, required very high to high pressure, anticorrosive, inner low defect, comprehensive mechanical property.
The shortcoming that existing two kinds of methods exist is: when machining removes excess metal, and machine-finish allowance is large, and the process-cycle is long, and waste of material is large, and manufacturing cost is high.
Utility model content
The purpose of this utility model is the feature manufacturing spheroid shape housing part Problems existing and drawback and product self for conventional method, a kind of mould of forging elliposoidal Shell Forging Parts is provided, utilize this mould that forging machine direction conformal can be made to distribute, machine-finish allowance is little, and product stable mechanical performance and service life extend.
The technical solution of the utility model is:
A kind of mould of forging elliposoidal Shell Forging Parts, primarily of preformed frock and forming frock composition, described preformed frock is by gooseneck boom plug, preforming mould forms, gooseneck boom plug is arranged on below preforming mould, preforming work face on the lug boss of the bulge shape that gooseneck boom plug is arranged and preforming mould forms preforming work district, described forming frock is by forming core rod, upper shaping mould, compacted under mould forms, upper shaping mould and compacted under mould form the outer shape die cavity of elliposoidal Shell Forging Parts, forming core rod is inserted in the die cavity that upper shaping mould and compacted under mould formed with manner.
Further, described preforming work face is provided with chevron shape's structure of arch in the horizontal, and preforming work face is circular shape on vertical.
Further, described gooseneck boom plug is fixedly installed on workbench.
Further, described forming core rod be inserted in shaping mould and compacted under mould the part formed in die cavity be tapered cylinder.
In the utility model, first raw material ingot heated and after being incubated, in forging temperature interval, carrying out repeated multiple times forging and stamping to change its structural state, seam internal flaw, and obtain cylindrical blank with drift punching, core bar drawing; Cylindrical blank is enclosed within gooseneck boom plug, then with preforming mould compacting also preformed; The preform that cylindrical blank obtains after preformed is enclosed within forming core rod again, then preform is placed between upper shaping mould and compacted under mould, upper shaping mould is suppressed downwards, preform is rotated by the rotation of forming core rod simultaneously, ensure that the periphery of preform can be subject to compacting and final molding, obtained elliposoidal Shell Forging Parts.
The beneficial effects of the utility model and advantage are:
Utilize mould of the present utility model can the elliposoidal Shell Forging Parts of forging different materials, obtain the distribution of its machine direction conformal of conical surface part, constant product quality, reliable, there are anti-high pressure and anticorrosion properties, and machining clout is little, material saving, process-cycle is short, low cost of manufacture.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but should not be interpreted as that the scope of theme described in the utility model is only limitted to following embodiment at this point, do not departing from the above-mentioned technological thought situation of the utility model, all make according to ordinary skill knowledge and customary means various amendments, replacement and change, include in scope of the present utility model.
As shown in Fig. 1 to 7, pulsation damper typically has inner chamber, elliposoidal housing part in irregular shape, conventional method manufactures spheroid shape housing part Problems existing and drawback, and the utility model design provides a kind of mould of forging elliposoidal Shell Forging Parts, and concrete structure is:
This device is made up of preformed frock and forming frock, described preformed frock is made up of gooseneck boom plug preforming mould 2, gooseneck boom plug 1 is arranged on below preforming mould 2, the lug boss 101 of the bulge shape that gooseneck boom plug 1 is arranged forms preforming work district with the preforming work face 201 on preforming mould 2, described forming frock is made up of forming core rod 3, upper shaping mould 4, compacted under mould 5, upper shaping mould 4 and compacted under mould 5 form the outer shape die cavity of elliposoidal Shell Forging Parts 7, and forming core rod 3 is inserted in the die cavity that upper shaping mould 4 and compacted under mould 5 formed with manner.
Described preforming work face 201 is provided with chevron shape's structure of arch in the horizontal, and preforming work face 201 is circular shape on vertical.
Described gooseneck boom plug 1 is fixedly installed on workbench.
