摘要： PROBLEM TO BE SOLVED: To provide an iron-based sintered alloy in which mechanical properties such as strength and dimensional stability before and after sintering can be secured while suppressing the use of Cu or Ni and also to provide its manufacturing method. SOLUTION: The iron-based sintered alloy is an iron-based sintered alloy obtained by sintering a powder compact prepared by compacting a raw-material powder composed mainly of Fe and has a composition consisting of, by mass, 0.1 to 1.0% C, 0.01 to 1.5% Mn, 0.02 to 3.5% (Mn+Si) and the principal balance Fe when the total is 100 mass%. It is found out that the use of proper amounts of Mn and Si can strengthen the iron-based sintered alloy and develop excellent dimensional stability. As the result, the use of Cu or Ni hitherto considered to be almost essential for the strengthening of the iron-based sintered alloy can be suppressed or eliminated and the recyclability of the iron-based sintered alloy can be improved, and further, cost reduction can be attained.

摘要： PROBLEM TO BE SOLVED: To provide an ultrahigh density sintered compact having excellent dimensional stability.
SOLUTION: The iron-based sintered alloy member is an iron-based sintered alloy member obtained by sintering a powder compact prepared by compacting a raw-material powder composed mainly of Fe and has a composition consisting of, by mass, 0.01 to 2% Si, 0.1 to 0.8% C and the principal balance Fe when the total is 100 mass%, and further, the density ratio of the sintered compact, as a ratio of bulk density to theoretical density, is made to a high density of ≥96%. Even in the case where a C-containing ultrahigh density powder compact is sintered, the occurrence of blister in the sintered compact can be suppressed by the incorporation of Si and the dimensional stability of the sintered compact can be secured.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method which inexpensively provides a Cu-free iron-based sintered alloy excellent in various properties. SOLUTION: The method for manufacturing the iron-based sintered alloy includes a molding step of compression molding a starting material powder of a mixture of an Fe-based powder and a reinforcing powder to form a powder compact, and a sintering step of heating and sintering the powder compact in an antioxidant atmosphere. The reinforcing powder is an Fe-Mn-Si-C powder of an Fe alloy or an Fe compound that contains 58-70% Mn, Si resulting in a composition ratio (Mn/Si) of Mn to Si of 3.3-4.6, and 1.5-3% C, relative to 100% of the total powder by mass. This Fe-Mn-Si-C powder can be procured relatively inexpensively, and various properties of the iron-based sintered alloy obtained using the powder are superior to those of a conventional iron-based sintered alloy. Accordingly, a reduction in the cost of the Cu-free iron-based sintered alloy excellent in various properties is achieved. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To feed a fixed amount of powder to a die of a powder molding press in a short period of time.
SOLUTION: A powder box 20 has a powder volume exceeding the amount of powder required for single molding. Thus, in a position P2 just above the cavity 26 of a die 24, even after the charge of the powder to the cavity 26, a state where the powder is left in the powder box 20 comes out. But, the remaining amount of the powder in the powder box 20 is affected by the leakage of the powder, or the like and is not fixed, the amount of the powder remaining in a subhopper 16 after the blowing-off of the powder to the powder box 20 is varied. The amount of the remaining powder in the subhopper 16 is detected by a powder amount detection sensor 22, and a powder weighing machine 14 is controlled in such a manner that, based on the detected result, the amount of the powder regulated based on the amount of the powder required for single molding is cut out. In this way, the amount of the powder in the powder box 20 is made stable, and the amount of the powder charged from the powder box 20 to the cavity 26 is made stable as well.

摘要： PROBLEM TO BE SOLVED: To provide the method for charging with the powder, by which charging a cavity uniformly with the powder is further secured. SOLUTION: By inserting a tube 3 into the powder 6 after charging the cavity 5, making gas flow out through the gas flowing-out ports 4 of the tube and giving again fluidity to the powder 6 in the cavity, the charging is made uniform. Next, by making the diameters of the gas flowing-out ports 4 formed on the tube 3 larger on the outlet side than those on the inlet side to make the flow rate of the gas at an outlet lower and controlling dispersion and flying up of the powder 6 in a powder box 2, the uniform charging is promoted.

摘要： PURPOSE:To perform extremely quickly the measurement of a molding and the stage from said measurement up to control by feeding back the packed amt. of raw material powder in accordance with the size value between top and bottom molds detected in the state of pressurizing the raw material powder. CONSTITUTION:An upper punch 2 is brought down to compress the raw material powder supplied into a cavity 6 between said punch and a lower punch 4. The distance between the punches 2 and 4, that is, the thickness H'0 of a molding 9, is measured with a detector 13 and a detecting element 14. The result thereof is inputted to a control circuit 17 where the discrimination of whether the error thereof with respect to the preset thickness (standard) Hs is within a prescribed range or not is accomplished. If the error is within the range, the molding is withdrawn, and if the error exceeds the range, whether the error is + or - is judged. In the case of +, a signal is sent from the circuit 17 to a motor 10 which moves a die 5 downward to decrease the substantial volume of the cavity 6. In the case of -, the volume is conversely increased, whereafter the molding 9 is withdrawn.
