Embodiment 1
[0025] Step 1: Use -100 mesh iron powder soft magnetic material with a Fe purity content of 98.5%, add a forming agent zinc stearate accounting for 0.4% of the total mass, fully mix in a V-shaped mixer, and loosely pack the powder The density is controlled at 2.6g / cm3,
[0026] Step 2: Use FWCuSn6Zn6Pb3-Ⅲ tin bronze powder, add a forming agent zinc stearate accounting for 0.5% of the total mass, and mix well in a V-type mixer, and the bulk density of the material is controlled at 3.5g / cm3.
[0027] Step Three: See figure 1 , figure 2 , put the powder material in step 1 into the female mold cavity of the mold, and the unit pressing pressure is 5-7T / cm 2 Under the conditions of pressing and forming, the blanks A1 and A2 are made, and the density of the blank is controlled at 6.4-6.6g / cm 3 ,
[0028] Step 4: The blanks A1 and A2 are sintered in a continuous sintering furnace under a protective atmosphere of a mixed gas of 40% liquid nitrogen gas and 60% ammonia decomposition...
Embodiment 2
[0034] Step 1: Use -100 mesh iron powder soft magnetic material with a Fe purity content of 99.5%, add a forming agent accounting for 0.6% of the total mass, and fully mix it in a V-type mixer, and the bulk density of the powder is controlled at 2.8 g / cm3,
[0035] Step 2: Use FWCuSn6Zn6Pb3-Ⅲ tin bronze powder, add 0.7% of the total mass of forming agent, fully mix in a V-shaped mixer, and control the bulk density of the material at 4.4g / cm3,
[0036] Step Three: See figure 1 , figure 2 , put the powder material in step 1 into the female mold cavity of the mold, press and form under the condition of unit pressing pressure 7T / cm2, and make blanks A1 and A2, and the density of the pressed blanks is controlled at 6.6g / cm3,
[0037] Step 4: The blanks A1 and A2 are sintered in a continuous sintering furnace under a protective atmosphere of a mixed gas of 40% liquid nitrogen gas and 60% ammonia decomposition gas. The blanks first enter the pre-sintering zone, the pre-sintering t...
Embodiment 3
[0043] Step 1: Use -100 mesh iron powder soft magnetic material with a Fe purity content of 99.%, add a forming agent zinc stearate accounting for 0.5% of the total material, and mix well in a V-shaped mixer until the powder is loose The packing density is controlled at 2.7g / cm3,
[0044] Step 2: Use FWCuSn6Zn6Pb3-Ⅲ tin bronze powder, add 0.6% of the forming agent zinc stearate in the total material, and fully mix in a V-shaped mixer to obtain a powder material. The bulk density of the material is controlled at 4g / cm3.
[0045] Step Three: See figure 1 , figure 2 , put the powder material in step 1 into the female mold cavity of the mold, press and form under the condition of unit pressing pressure 6T / cm2, and make blanks A1 and A2, and the density of the pressed blanks is controlled at 6.5g / cm3,
[0046]Step 4: The blanks A1 and A2 are sintered in a continuous sintering furnace under a protective atmosphere of a mixed gas of 40% liquid nitrogen gas and 60% ammonia decompos...
