Abstract
A technology for manufacturing shaped high-specific weight alloy parts includes such steps as mixing W-based powder containing Cu and Ni with binder, injection shaping, degreasing and sintering. Said binder is prepared from polyethene glycol, polyethylene, plasticizer and paraffin through mixing. Its advantages include uniform inner tissue, high density up to 99.5-100%, high mechanical performance and accurate size, high surface finish quality, integral shaping and low cost.
Description
It is metal powder injection molded to the present invention relates to a kind of usefulness, makes special-shaped high-density alloy machining parts.
The handset vibrator that communication is used, beeper oscillator, deep-sea fishing all is a little special-shaped high specific gravity metal parts with weight etc., requires density even, the dimensional accuracy height.Adopt the technology of powder pressing, produce handset vibrator, because draw ratio is big, density is even everywhere to be not easy to make goods, and it has the step of a 0.2mm simultaneously, needs back processing to obtain.The beeper oscillator has geometrical bodies such as circular arc and through hole, can not once extrude, and also needs following process.And high-density alloy hardness is big, processing difficulties, and the cost height, and be difficult for ensuring the quality of products.
Purpose of the present invention is that a kind of method with powder injection forming will be provided, and produces special-shaped high-density alloy part.
Abnormity high-density alloy machining parts is that the tungsten based powders of cupric 7-1%, nickeliferous 14-2% is mixed with binding agent, is machined to base through injection moulding, degreasing again, sintering.
Introduce the present invention in detail below in conjunction with embodiment.
The preparation of a, binding agent: by weight percentage, taking polyethylene glycol 10-40%, polyethylene 15-40%, plasticizer 1-10%, paraffin 10-74% puts in the vane type batch mixer, mixes hour through 1 under 140-160 ℃ of temperature.
B, batching: the tungsten based powders of binding agent and cupric, nickel, by volume 48-40: 52-60 cooperates, and mixes 1.5 hours under 140 ° of-160 ℃ of temperature in batch mixer.
C, injection moulding: above-mentioned batch mixing is placed in the injection machine, and with 140 °-150 ℃, injection pressure 40-80Mpa under 30 ° of-60 ℃ of conditions of mould temperature, is processed into blank.
D, degreasing: at first blank is put into water and be heated to 40 °-60 ℃, be detained 30 minutes, the polyethylene glycol component in the dissolving binding agent; Then blank is put into debinding furnace, under hydrogen shield, be heated to 260 ℃ with 5 ℃/min speed, the speed with 10 ° of-15 ℃/min is heated to 500 ℃ then.
E, sintering: earlier the degreasing blank is heated to 800 °-900 ℃ and does presintering, place molybdenum wire furnace again, at 1350 °-1400 ℃ of temperature, sintering 90 minutes.
Adhesive preparation of the present invention.
Embodiment 1: taking polyethylene glycol 20%, polyethylene 30%, plasticizer 5%, all the other are paraffin, put in the vane type batch mixer, mix 1 hour under 140 ° of-160 ℃ of temperature.
Embodiment 2: taking polyethylene glycol 10%, polyethylene 15%, plasticizer 1%, all the other are paraffin, put in the vane type batch mixer, mix 1 hour under 140 ° of-160 ℃ of temperature.
Embodiment 3: taking polyethylene glycol 40%, polyethylene 40%, plasticizer 10%, all the other are paraffin, put in the vane type batch mixer, mix 1 hour under 140 ° of-160 ℃ of temperature.
Use the processing profiled high-density alloy part of the present invention, interior tissue is even, and product density can reach 99.5-100%, good mechanical property, and the dimensional accuracy height, surface smoothness is good, and once-forming need not back processing, reduces cost greatly.
