Abstract
The utility model discloses a kind of mould preparing multiple proportioning powder metallurgy self-lubricating joint inner ring.Mould comprises outer mold, inner mold, upper bed-plate, lower bottom base, seaming chuck, push-down head.The beneficial effects of the utility model are: (1) this mould selects graphite to be raw material, and mould structure is simple, with low cost, simple, convenient, long service life; (2) the self-lubricating knuckle bearing inner ring of the dusty material of three kinds of different ratio can be sintered out, and each proportioning can sinter out two self-lubricating knuckle bearing inner rings, improves sintering efficiency, reduces energy resource consumption at every turn simultaneously.
Description
Technical field
The utility model relates to powder metallurgy hot pressing and sintering technique field, particularly relates to a kind of mould preparing multiple proportioning powder self-lubricating metallurgical joint inner ring.
Background technology
Powder metallurgy self-lubricating joint inner ring is with metal dust and kollag for raw material, adopts cold moudling and hot extrusion briquetting technique, obtains the oscillating bearing inner ring of heterogeneity proportioning.Traditional casting and Machining Technology are difficult to manufacture self-lubricating knuckle bearing inner ring, and allowance is large, causes a large amount of manpowers, financial resources, waste of material.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model has supplied a kind of mould preparing multiple proportioning powder metallurgy self-lubricating joint inner ring.
The technical scheme that the utility model adopts is: a kind of mould preparing multiple proportioning powder self-lubricating metallurgical joint inner ring, comprises outer mold, inner mold, upper bed-plate, lower bottom base, seaming chuck, push-down head.
Described mould raw material is graphite, described inner mold is encased in outer mold, described powder loads in inner mold, upper push-down head is respectively charged into the two ends up and down of inner mold, described seaming chuck loads in the locating hole of upper bed-plate, push-down head loads in the locating hole of lower bottom base, and described lower bottom base is connected by boss with outer mold.
The internal diameter of described outer mold is equal with inner mold external diameter, has two cavitys in inner mold, and there is a pressure head each cavity one end.
The equal diameters that described upper bed-plate has three locating holes, lower bottom base has three locating holes and the diameter in hole and pressure head, locates time the effect of locating hole is pressurization, makes each pressure head uniform force.
Compared with prior art, the beneficial effects of the utility model are that this mould selects graphite to be raw material, and mould structure is simple, with low cost, simple, convenient, long service life; Can sinter out the self-lubricating knuckle bearing inner ring of the dusty material of three kinds of different ratio, and each proportioning can sinter out two self-lubricating knuckle bearing inner rings, improves sintering efficiency, reduces energy resource consumption at every turn simultaneously.

Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of mould preparing multiple proportioning powder self-lubricating metallurgical joint inner ring, comprises outer mold, inner mold, upper bed-plate, lower bottom base, seaming chuck, push-down head.Described inner mold 4 loads in outer mold 3, described powder is encased in inner mold 4, seaming chuck, push-down head are respectively charged into inner mold about 4 two ends, three described push-down heads 5 load in three locating holes of lower bottom base 6, described lower bottom base 6 is connected with outer mold 3 by boss, and three described seaming chucks 2 load in three locating holes of upper bed-plate 1.
As shown in Figure 4, two cavitys are had inside described inner mold 4.
During use, first mixed powder (metal dust and solid lubrication agent composition) to be loaded in inner mold 4 in upper plenum, again three seaming chucks 2 are loaded the upper end of three inner molds 4, then cold moudling on hydraulic pressure testing machine is placed on, the lower cavity of same method to inner mold 4 fills powder, cold moudling.Then be encased in outer mold 3 by three inner molds 4, three seaming chucks 2 are encased in three locating holes of upper bed-plate 1, and three push-down heads 5 are encased in three locating holes of lower bottom base.Then the mould assembled is put in vacuum sintering funace and carry out hot pressed sintering.
