In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the system architecture schematic diagram of Powder Metallurgy Injection Moulding manufacturing installation of a kind of tungsten alloy armor-piercing bullet square pellet of the utility model embodiment.
Fig. 2 is the process flow steps schematic diagram of Powder Metallurgy Injection Moulding manufacturing installation of a kind of tungsten alloy armor-piercing bullet square pellet of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, the technical process of the Powder Metallurgy Injection Moulding manufacturing installation of a kind of tungsten alloy armor-piercing bullet square pellet that the utility model embodiment provides, below take that to use tungsten alloy square be example, and the quantity of every mould is brought up to more than 1000 from tens, the steady quality of product, homogeneity is very good, and after sintering, dimensional stability improves greatly, and without push rod vestige and gate vestiges, omitted follow-up process for machining, the time of implementation is 20-30 hour, and benefit increases substantially:
1, alloy powder is selected the powder below granularity 10 μ m, mainly contains: Mo powder, Cr powder, W powder, Ni powder, Cu powder, C powder, Fe powder; Utilize mechanical alloy module to carry out mechanical alloy metallization processes, by above-mentioned alloy powder in high energy ball mill with specific rotating speed and rational ratio of grinding media to material, by impacting intensely for a long time, collide, rub between powder particle and abrading-ball, make powder particle repeatedly produce cold welding, fracture, cause the diffusion of powder particle Atom, thereby obtain alloying powder; In most cases, on point, line and the face that only makes each constituent element contact at those in limited Ball-milling Time, reach or convergence atom level distance, and just each constituent element very uniform mixture of distribution or compound of finally obtaining, when Ball-milling Time extends, also can pass through solid-state diffusion, make each constituent element reach combination between atom and form alloy or compound.This method has improved sintering power greatly, and very large effect is played in the diffusion during to sintering;
2, select twin-screw extrusion batch mixer, temperature is controlled at 180 ± 10 ℃, by technique, adds respectively metal dust, binding agent, and the order in accordance with regulations that adds of binding agent adds, mixing time 30-40min;
