Description

The continuous shaping device of metal injection moulding part roll extrusion
Technical field
The utility model relates to metal powder injection molding improvement opportunity, especially the continuous shaping device of metal injection moulding part roll extrusion.
Background technology
Metal injection moulding (Metal Injection Molding, be called for short MIM) be a kind of Novel powder metallurgy near-net-shape technology of extending out from injection molding of plastics industry, metal injection moulding is the forming method that a kind of plasticising compound by metal dust and its binding agent is injected in model.It is the constitutional detail utilizing mould injection moldable blank and manufactured high density, high accuracy, high strength, three-dimensional complex shapes by sintering fast, especially some planform complexity utilize method processing or unmanageable miniature parts such as machining, metal powder injection molding can complete freely, there is the advantage that cost is high, efficiency is high, uniformity is good, easy formation batch production, is described as " parts forming technique the most popular now ".
The basic process steps of metal injection moulding is: be first choose the metal dust and binding agent that meet MIM requirement, then adopt suitable method that powder and binding agent are mixed into uniform feeding at a certain temperature, at injection moulding after granulating, shaping base sintering densification after ungrease treatment of acquisition becomes final finished.The object of injection moulding be obtain the zero defect of required form, uniform particles row by MIM shaping base substrate.As shown in Figure 1, first granular feeding is heated to necessarily high temperature and makes it to have mobility, being then injected in die cavity cools down obtains the base substrate with certain rigidity of required form, then it is taken out from mould and obtains MIM shaping base.This process is consistent with traditional injection molding of plastics process, but due to the high content of powder of MIM feeding, makes its injection moulding process there is very big difference on technological parameter and in some other, controls improperly then easily to produce various defect.Sintering is the final step operation in MIM technique, sinters the hole eliminated between powder particle. make MIM product reach complete fine and close or close entirely densified.MIM product is due to complex-shaped, and sintering shrinkage is large, still needs to carry out sintering post processing after most of product has sintered, heat treatment, fine grinding, ionic nitriding, plating, the peening surface treatment etc. such as comprise shaping, carburizing, nitriding, carbon one nitrogen ooze altogether.
But conventional shaping operation technique, needs to be placed on the counterdie that pre-sets with hand by product after sintering, then repeatedly piecemeal carry out shaping, need to waste a large amount of time, not only inefficiency, the labour intensity of workman is large, the automaticity of equipment is low, and, adopt manual operation, the stability of product in process and precision can not be guaranteed, there is certain potential safety hazard, very easily causing because operating the security incident caused lack of standardization.
On the other hand, present stage is badly in need of the part in the product of the large batch of manufacture that the short time pays for the big customer extensively existed, delivery every day amount is huge, after MIM processing procedure, all has deformation of products problem, if in artificial mode, do shaping with tool to correct and detect, according to existing condition hand-manipulated, even if the manpower correcting and detect is 24hr two classes of about 40 people, 40000 can only be accomplished at most, still far can not meet the interim emergency requirement of client.If only so manually enhanced production capacities to increase to join, unrealistic.
