Abstract
The invention relates to a pressure casting device and method for producing a high-melting-point metal-coated potsherd material. The pressure casting device comprises a forming mold tank and a preheating mechanism. The forming mold tank and the preheating mechanism are arranged on one side of a crucible. A gravity pressure head capable of moving vertically is arranged above the preheating mechanism and provided with a vibrating mechanism and a lifting cylinder.

Description
Technical field
The present invention relates to material processing field, relate to a kind of die casting equipment for refractory metal coating ceramic chip material and forming method specifically.
Background technology
Traditional metal forming is mainly divided into two classes: a class is the liquid forming of metal, as casting, liquid forging, directly casting, continuous casting etc.; Another kind of is the solid molding of metal, as rolling, drawing, extruding, forging, punching press etc.A kind of new method of metal forming is proposed, i.e. semi-solid processing professor Flemimgs etc. of 20 century 70 Massachusetts Institute Technologies.Semisolid Metal Processing is exactly in metal solidification process, violent stirring action is imposed to it, the nascent solid phase of abundant break down dendritic, obtain the solid-liquid mixed slurry (solid phase components is generally about 50%) that left floating certain spherical nascent solid phase in a kind of liquid metal mother liquor equably, i.e. rheological slurry, the method utilizing this rheological slurry directly to form processing is referred to as the rheological molding (rheoforming) of semi-solid-state metal; If rheological slurry is frozen into ingot, connects and need this ingot to be cut into a certain size, then reheat (i.e. the post bake of blank) semi-solid temperature district to metal, ingot is at this moment commonly referred to as semisolid metal blank.Utilize the semi-solid blank of metal to form processing, this method is referred to as thixotropic forming (thixoforming).Above-mentioned two kinds of manufacturing process of semi-solid-state metal are collectively referred to as semi-solid-state shaping or the semi-solid processing (semi-solid forming or processing of metals) of metal, at present in the world, usually by semi-solid processing referred to as SSM (semi-solid metallurgy).
With regard to metal material, semisolid be its from liquid state to Solid State Transformation or from solid-state to the interstage of liquid state, especially for the interval wide alloy of crystallization temperature, the semisolid stage is longer.Metal material all presents visibly different physical characteristic at liquid, solid-state and semisolid three phases, utilizes these characteristics, creates various metals heat processing and forming methods such as solidifying processing, plastic working and semi-solid processing.
Solidify the good fluidity of processing and utilization liquid metal, to complete filling in forming process, feeding until solidify end.Its development trend adopts mechanical pressure to substitute gravity stowing, thus improves drip molding internal soundness and dimensional accuracy. but from freezing mechanism angle, it is extremely difficult for solidifying that processing wants to eliminate drip molding internal flaw completely, or even impossible.
The good plastic fluidity that plastic working utilizes solid metallic at high temperature to present, to complete deformation in forming process and structural transformation.With solidify compared with processing, the product quality adopting plastic working to be shaped is obviously good, but due to solid metallic resistance of deformation high, required deformation force is large, equipment is also very huge, therefore will consume mass energy, often needs multi-steps forming operation just can complete for complex parts.Therefore, the developing direction of plastic working reduces power consumption of polymer processing and cost, Reducing distortion resistance, raising size of formed part precision and surperficial and internal soundness.The modern plastic processing methods such as precision die forging, isothermal forging and superplasticity processing are there is thus.
Semi-solid processing utilizes metal from liquid state to Solid State Transformation or the method that forms from the solid-state characteristic had to liquid state (namely liquid-solid coexist) process.This new forming and machining method combines the strong point of solidifying processing and plastic working.Namely processing temperature than liquid low, resistance of deformation is less than solid-state, aximal deformation value can shape complex-shaped and precision and the higher part of performance quality requirements.So semi-solid processing is called 21 century the most promising material forming processing method by the expert abroad had.
In recent years, under the support that the researcher of China plans in state natural sciences fund, national " 863 ", " 973 " etc., in Semi-solid Processing Technologies for Aluminum Alloys development and application, good basis had been possessed.To the basic key technology of aluminium alloy semi-solid processing, comprise the aspects such as semi-solid material technology of preparing, post bake technology and semisolid pressure casting technology, possess the technical foundation transformed to industrialization.The basic research of ferrous materials semisolid direct forming has been carried out in University of Science & Technology, Beijing and the cooperation of metal Suo Deng unit of the Chinese Academy of Sciences under the support of state natural sciences fund, prepare at the semi-solid blank of the materials with high melting point such as cast iron, spring steel, stainless steel and high-carbon steel, semisolid spray to cast is shaped and carried out comparatively furtheing investigate in Direct Rolling etc., and achieving phasic results.Beijing Non-Ferrous Metal Research General Academy has made great progress on the investigation and application of Semi-solid Processing Technologies for Aluminum Alloys under the support of national " 863 " plan and institute's science fund, by cooperating with Dong Feng Auto Corporation, semisolid pressure casting technology is adopted to achieve the batch production of automobile air compressor connecting rod and air-conditioner turbine two kinds of auto parts in production scene.
But up to the present, also do not have the device of refractory metal coating ceramic fragment to report.
