Background technology
Precision and the surface roughness of the spherical bearing size adopting powder metallurgy die to produce all do not include too high, in order to obtain precision and the surface roughness of required size, need to suppress again sintered part, sintered part surface is made to produce plastic deformation, to correct its size and distortion, Here it is finishing mold, finishing mold of the prior art adopts finishing mode in outer hoop, the pressure that this method mould bears is little, favourable to mould, but the press needing tonnage large.The utility model proposes a kind of finishing mold of powder metallurgy spherical bearing of band oil nozzle newly.
Utility model content
In order to solve Problems existing in background technology, the utility model provides a kind of finishing mold of the powder metallurgy spherical bearing with oil nozzle, this finishing mold adopts the mode finishing mold of outer hoop internal expanding, have and use press tonnage little, the advantages such as the dimensional accuracy of the sintered part of finishing improves greatly, surface roughness reduction.
For achieving the above object, the utility model adopts following technical scheme:
A finishing mold for powder metallurgy spherical bearing with oil nozzle, comprises base, cope match-plate pattern, lower bolster and frame, it is characterized in that,
Base is arranged on the ground, base is fixed with prop liner by base fixed block, prop liner is fixed with pillar, the middle part of pillar is arranged with back-up block, back-up block is provided with buffer stopper, buffer stopper is fixed with low punch by low punch fixed block, low punch is the cylindrical shape of hollow, it is set on pillar, bottom low punch, there is stage portion, low punch fixed block is provided with the projection corresponding with stage portion, after projection engages with stage portion, low punch is fixed on buffer stopper, between the inner chamber of low punch and pillar, there is space, plug is inserted in this space, plug top is provided with bolt hole, after bolt inserts this bolt hole, plug is fixed on pillar,
The circumferential side wall of low punch is fixed with lower bolster, and lower bolster is provided with along the sidewall of low punch the lower plastic chamber caved inward, and lower plastic chamber is provided with oil nozzle in the bottom of lower bolster side;
Frame is fixed with cope match-plate pattern by cope match-plate pattern fixed block, and the central authorities of cope match-plate pattern have cavity, are provided with plastic chamber in cavity, and the bottom of upper plastic chamber has accent, and the diameter of accent is greater than the diameter of plug.
The connected mode of described pillar and prop liner is: pillar inserts in prop liner, and prop liner bottom surface is inserted with bolt to length, and bolt extend in pillar and fixed by pillar.
The top of cope match-plate pattern has stage portion, and cope match-plate pattern fixed block has protuberance corresponding with it, and after protuberance engages with stage portion, cope match-plate pattern is fixed in frame.
The beneficial effects of the utility model are: this finishing mold adopts the mode finishing mold of outer hoop internal expanding, have and use press tonnage little, the advantages such as the dimensional accuracy of the sintered part of finishing improves greatly, surface roughness reduction.
Accompanying drawing explanation
