Abstract
The invention discloses a powder metallurgy guide seat and a manufacturing method thereof. Copper powder, graphite, lubricants, sulfur and reduced iron powder are used as materials, and the materials are uniformly mixed, pressed on a press and then sintered. Components of the materials are adjusted, the green strength of the guide seat is improved by the aid of the reduced iron powder, the sulfur is added into the materials, on one hand, excessive carbide can be suppressed to improve the rigidity and the roughness of the guide seat by the aid of the sulfur, so that the guide seat is not easily broken, on the other hand, parts of sintered products form iron sulfide with a self-lubricating function, the self-lubricating property and the anti-seizure property of the guide seat can be improved, the service life of the guide seat is prolonged, and a mating plate-piston rod is effectively protected.
Description
Technical field
The present invention relates to a kind of manufacture method of powdered metal parts, relate in particular to a kind of powder metallurgy guide seat and manufacture method thereof.
Background technology
Guide holder is parts important in automobile, motorcycle vibration absorber, all there is to strict requirement the aspects such as its intensity, self-lubricating property, its intensity index of guide holder of using on market is now in 350MP left and right, hardness is at HB60-IIO, can substantially meet instructions for use, but be also often damaged, and pull the phenomenon of piston rod, to user, bring very big inconvenience.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of powder metallurgy guide seat and manufacture method thereof that can improve guide holder intensity, hardness and self-lubricating property.Technical scheme of the present invention is: it is take copper powder, graphite, lubricant, sulphur and reduced iron powder as material, and the percentage by weight of each material is: copper powder 1%-2%, graphite 1.5%-2%, lubricant 0.6%-0.8%, sulphur 0.3%-0.5%, all the other are reduced iron powder.
Each mixing of materials is stirred, then place it on press compressingly, then under 1083 ℃ of-1100 ℃ of conditions, sintering forms.
Beneficial effect of the present invention: for the present invention adjusts in the component of material; iron powder is used reduced iron powder; improved the green strength of guide holder; and in material, added sulphur; sulphur can suppress the too much generation of carbide on the one hand; rigidity and the toughness of guide holder have been improved; make it to be difficult for rupturing; product section after sintering forms iron sulfide on the other hand; iron sulfide has self-lubricating function; can improve self-lubricating property and the anti-bite axle performance of guide holder, improve the service life of guide holder, effectively protect mating plate---piston rod.
The specific embodiment
Embodiment 1
The present invention is take copper powder, graphite, lubricant, sulphur and reduced iron powder as compound, and the percentage by weight of each material is: copper powder 1%, graphite 1.59%, lubricant 0.6%, sulphur 0.3%-0.5%, all the other are reduced iron powder.Each mixing of materials is stirred, then place it on press compressingly, then under 1100 ℃ of conditions, sintering forms.
Embodiment 2
The present invention is take copper powder, graphite, lubricant, sulphur and reduced iron powder as compound, and the percentage by weight of each material is: copper powder 2%, graphite 2%, lubricant 0.8%, sulphur 0.3%-0.5%, all the other are reduced iron powder.Each mixing of materials is stirred, then place it on press compressingly, then under 1083 ℃ of conditions, sintering forms.
Claims (2)
