Abstract
The invention discloses a device for forging a forge piece with an ellipsoidal shell. The device mainly comprises a pre-forming device and a forming device, wherein the pre-forming device is composed of a goose-head-shaped core rod and a pre-forming mould; the goose-head-shaped core rod is arranged below the pre-forming mould; a bump type protruding part arranged on the goose-head-shaped core rod and a pre-forming working surface on the pre-forming mould form a pre-forming working area; the forming device is composed of a forming core rod, an upper forming mould and a lower forming mould; the upper forming mould and the lower forming mould form the external cavity of the forge piece with the ellipsoidal shell; and the forming core rod is movably inserted into the cavity composed of the upper forming mould and the lower forming mould. The device for forging the forge piece with the ellipsoidal shell disclosed by the invention can be utilized for forging the forge piece with the ellipsoidal shell, made of different materials; the fibre direction of the obtained forged piece with the conical surface is distributed in a conformal manner; and the device for forging the forge piece with the ellipsoidal shell disclosed by the invention is steady and reliable in quality, material-saving, short in machining period and low in manufacture cost, and machining excess materials are few in quantity.
Description
Technical field
The invention belongs to the technical field of forging in machine-building, particularly a kind of forging device of elliposoidal Shell Forging Parts.
Background technology
In machine made field, having the classical production process of inner chamber, elliposoidal housing part in irregular shape for inside is generally to adopt the mode moulding of forging solid forging, and then by boring, the inner unnecessary surplus of turning is produced, the product that this mode is produced, because forging internal fiber direction is cut off, has reduced its comprehensive mechanical property and service life; Or adopt casting straight forming, but interior tissue and mechanical property are wayward, have material structure problem pockety, cause comprehensive mechanical property to be difficult for meeting the instructions for use of pressure vessel.
If pulsation damper is typically to have inner chamber, elliposoidal housing part in irregular shape, be pressure vessel one of key element, and pulsation damper is as the main pressurized part of its equipment, very strict to its quality requirement, when 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 is removed excess metal, machine-finish allowance is large, and the process-cycle is long, and waste of material is large, and manufacturing cost is high.
Summary of the invention
The object of the invention is to manufacture the problem of spheroid shape housing part existence and the feature of drawback and product self for conventional method, a kind of forging device of elliposoidal Shell Forging Parts is provided, utilize this device can make forging machine direction conformal distribute, machine-finish allowance is little, and product stable mechanical performance and service life extend.
Technical scheme of the present invention is:
A kind of forging device of elliposoidal Shell Forging Parts, mainly formed by pre-shaping device and shaped device, described pre-shaping device is by gooseneck boom plug, preforming mould composition, gooseneck boom plug is arranged on preforming mould below, preformed working face on lug boss and the preforming mould of the bulge shape arranging on gooseneck boom plug forms preformed workspace, described shaped device is by forming core rod, upper shaping mould, compacted under mould composition, upper shaping mould and compacted under mould form the external shape die cavity of elliposoidal Shell Forging Parts, forming core rod is inserted in the die cavity of upper shaping mould and compacted under mould formation with manner.
Further, described preformed working face is provided with the herringbone shape and structure of arch in the horizontal, and preformed working face is circular shape on vertical.
Further, described gooseneck boom plug is fixedly installed on workbench.
Further, to be inserted in the part that shaping mould and compacted under mould form in die cavity be tapered cylinder to described forming core rod.
In the present invention, after first raw material ingot being heated and being incubated, in forging temperature interval, carry out repeated multiple times forging and stamping to change its structural state, seam internal flaw, and obtain tubular blank with drift punching, core bar drawing; Tubular blank is enclosed within on gooseneck boom plug, then with preforming mould compacting preformed; The preform that tubular blank obtains after preformed is enclosed within on forming core rod again, then preform is placed between upper shaping mould and compacted under mould, upper shaping mould is suppressed downwards, preform rotates by the rotation of forming core rod simultaneously, the periphery that ensures preform can be subject to compacting final molding, makes elliposoidal Shell Forging Parts.
Beneficial effect of the present invention and advantage are:
Utilize the elliposoidal Shell Forging Parts that device of the present invention can forging different materials, obtained its machine direction conformal of conical surface part and distributed, 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 present invention is described in further detail, but the scope that should at this point not be interpreted as theme of the present invention only limits to following embodiment, without departing from the idea case in the present invention described above, all various amendments, replacement and changes of making according to ordinary skill knowledge and customary means, include within the scope of the invention.
As shown in Fig. 1 to 7, pulsation damper is typically to have inner chamber, elliposoidal housing part in irregular shape, conventional method is manufactured problem and the drawback that spheroid shape housing part exists, and the present invention's design provides a kind of forging device of elliposoidal Shell Forging Parts, and concrete structure is:
This device is made up of pre-shaping device and shaped device, described pre-shaping device is made up of gooseneck boom plug preforming mould 2, gooseneck boom plug 1 is arranged on preforming mould 2 belows, the lug boss 101 of the bulge shape arranging on gooseneck boom plug 1 forms preformed workspace with the preformed working face 201 on preforming mould 2, described shaped device 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 external 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 form with manner.
