Abstract
The invention discloses a rotary forging die for a sealing nut. The rotary forging die comprises a bottom plate, a down pressing base with a center hole and an eccentric hole is arranged above the bottom plate, an ejection block is arranged on the periphery of the upper side of the center hole, a deviated rubber gasket is arranged in the eccentric hole, the top end of the deviated rubber gasket is higher than the eccentric hole, a center rubber gasket with the same height as the deviated rubber gasket is arranged in the center hole, a core bar is inserted in the part, above the center rubber gasket, of the center hole, a die sleeve is arranged above the deviated rubber gasket, a female die is arranged on the inner side of the die sleeve and comprises a lower female die body and an upper female die body, a square hole is formed inside the lower female die body, the outer side of the lower female die body is round, and the upper female die body is of a circular ring shape. Through the rotary forging die for an outer gear shaft, one-shot machining forming of the outer gear shaft is achieved, the axial density difference of a part is greatly reduced, the whole nut almost has the same compactness, and strength is greatly enhanced.
Description
Technical field
The invention belongs to mould applications, relate to a kind of sealing nut pendulum and roll over mould.
Background technology
Iron-copper bi-metal material is because its outstanding technology economy advantage, and all achieve successful application in a lot of field, as sealing nut, because the instructions for use of its high strength and high torsional forces, the performance of people to bimetal structure material there has also been higher requirement.Usual people adopt following several method to produce this class part, one, centrifugal casting; Two, the combined sintering of powder compact and steel bushing; Three, make iron-based and Cu-base powder global formation and integral sintered by conventional powder metallurgical method; Four, compression casting.This several method respectively has its pluses and minuses, the inside parts of casting always also exists casting flaw unavoidably, qualification rate is low, labour intensity is large, environment is poor, be difficult to large-scale production, and the combined sintering of Cu-base powder pressed compact and steel bushing, the bond strength of its faying face is the part of its weakness all the time, although ordinary powder metallurgy method method produces bimetallic part can overcome the defects such as mo(u)lded piece internal shrinkage and component segregation, and composition is adjustable, but unless employing extrudes, the densified means such as high temperature insostatic pressing (HIP) or forge hot, or use great tonnage press, otherwise be difficult to obtain satisfied density, and these follow-up densified means all need large fund input, technical process relative complex.
Summary of the invention
In order to solve above-mentioned technology Problems existing, the invention provides a kind of sealing nut pendulum and rolling over mould.
Technical scheme of the present invention is: a kind of sealing nut pendulum rolles over mould, comprise base plate, the down pressing seat with centre bore and eccentric orfice is provided with above described base plate, above described centre bore, periphery is provided with jacking block, the inclined rubber blanket that top exceeds eccentric orfice is provided with in described eccentric orfice, consistent with inclined rubber blanket height hollow rubber pad is provided with in described centre bore, plug is inserted in centre bore above described hollow rubber pad, die sleeve is provided with above described inclined rubber blanket, die is provided with inside described die sleeve, described die comprises inner side for square opening, outside is circular lower cavity die and circular upper cavity die.
Preferably, described upper cavity die diameter of bore is less than the length of side of lower cavity die endoporus, the equal and opposite in direction of described upper cavity die external diameter and lower cavity die external diameter, and it is all identical with the internal diameter of die sleeve, described lower cavity die is enclosed within described jacking block, the upper surface of described upper cavity die, die sleeve and plug is in same level, and the junction of described die sleeve and die is positioned at the top of inclined rubber blanket.
Preferably, the surface of described upper cavity die is cambered surface.
Beneficial effect of the present invention: output gear shaft pendulum of the present invention rolles over mould, and the time processing achieving output gear shaft is shaping, substantially reduces the density contrast of the axis of part, the packing of whole nut is almost consistent, and intensity strengthens greatly.
Detailed description of the invention
Embodiment provided by the invention is described in further detail:
A kind of sealing nut pendulum of the present invention is rolled over mould and is comprised base plate, the down pressing seat with centre bore and eccentric orfice is provided with above described base plate, above described centre bore, periphery is provided with jacking block, the inclined rubber blanket that top exceeds eccentric orfice is provided with in described eccentric orfice, consistent with inclined rubber blanket height hollow rubber pad is provided with in described centre bore, plug is inserted in centre bore above described hollow rubber pad, die sleeve is provided with above described inclined rubber blanket, die is provided with inside described die sleeve, described die comprises inner side for square opening, outside is circular lower cavity die and circular upper cavity die.
Preferably, described upper cavity die diameter of bore is less than the length of side of lower cavity die endoporus, the equal and opposite in direction of described upper cavity die external diameter and lower cavity die external diameter, and it is all identical with the internal diameter of die sleeve, described lower cavity die is enclosed within described jacking block, the upper surface of described upper cavity die, die sleeve and plug is in same level, and the junction of described die sleeve and die is positioned at the top of inclined rubber blanket.
Output gear shaft pendulum of the present invention rolles over mould, the time processing achieving output gear shaft is shaping, save man-hour, save material, for next processing is provided convenience, shorten integrated machine process time, improve working (machining) efficiency, and the draw ratio of foundry goods reaches 3.1 > 2.5.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description is regarded in an illustrative, rather than a restrictive.
