Abstract
The utility model discloses a kind of aluminum matrix composite liner plate, comprise liner plate matrix, the backing surface layer be overlying on liner plate matrix, liner plate matrix adopts aluminum based composite material enhanced by granules in situ, and backing surface layer is tungsten carbide hard alloy coating prepared by detonation flame spraying method.The problem of effective solution wear liner and sizing; have that wearability is good, Antisticking, long service life, installation and maintenance and the advantage such as reparation is convenient; liner plate is used as protection ceramic die, the inefficacy avoiding mould in use because the problems such as ceramic powder wearing and tearing and sizing cause.Significantly improve the mold use life-span, raise the cost rate.
Description
Technical field
The utility model relates to a kind of mould liner plate, relates more specifically to a kind of wear-resisting, antiseized aluminum matrix composite liner plate.
Background technology
In ceramic die industry, the wearing and tearing of mould liner plate and sizing are technical barriers, are also ubiquitous outstanding problems in whole industry.For a long time, domestic ceramic die factory adopts multinomial corrective measure, such as, change liner material quality, change lining plate structure, paste multinomial measure, solution wear liner all not yet in effect and the problems of sizing such as alloy bar at backing surface.On the one hand, the wearing and tearing of die surface can cause product size bigger than normal; On the other hand, sizing can make again the size of product less than normal or local produce defect, cause yield rate obviously to reduce.But by sticking the method for alloy bar at ceramic die liner plate, the wearing and tearing of mould can be slowed down to a certain extent, but production cost is very high, and in use due to the aging of bonding agent and the fragility of alloy bar, often there is the cracking of alloy bar and loosen, affect quality and the production efficiency of product, the alloy bar life-span sticked is general also shorter, and frequent replacing is wasted time and energy.
Therefore, how designing that a kind of wearability for ceramic die is good, the liner plate of Antisticking, long service life, is industry technical problem urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art; a kind of aluminum matrix composite liner plate is provided; have that wearability is good, Antisticking, long service life, installation and maintenance and the advantage such as reparation is convenient; liner plate is used as protection ceramic die, the inefficacy avoiding mould in use because the problems such as ceramic powder wearing and tearing and sizing cause.
The technical scheme in the invention for solving the above technical problem is: a kind of aluminum matrix composite liner plate, comprise liner plate matrix, it is characterized in that: also comprise the backing surface layer be overlying on liner plate matrix, liner plate matrix adopts aluminum based composite material enhanced by granules in situ, and backing surface layer is tungsten carbide hard alloy coating prepared by detonation flame spraying method.
The thickness of described tungsten carbide hard alloy coating is 1-2mm.
Described liner plate matrix offers for coordinating the screwed hole installed with mould.
Compared with prior art, the beneficial effects of the utility model: significantly improve the mold use life-span, raise the cost rate, and installation and maintenance and reparation are conveniently.The tungsten carbide hard alloy coating of backing surface is as working face, and tungsten carbide hard alloy coating has the antiseptic property of high rigidity, smooth surface and excellence, not only improves the wearability of liner plate, extends the service life of liner plate, also can effectively solve sizing problem.Liner plate matrix is obtained by light high-intensity aluminum base composite, and aluminum matrix composite has good thermal conductivity, high strength and endurance, improves heat radiation and the anti-vibrating and impact performance of liner plate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further.
Refer to Fig. 1, the utility model relates to a kind of aluminum matrix composite liner plate, and comprise liner plate matrix 1 and backing surface layer 2, backing surface layer 2 is overlying on liner plate matrix 1.Liner plate matrix 1 is obtained by in-situ authigenic particle enhanced aluminum-based composite material, by particle enhanced aluminum-based composite material prepared by situ synthesis techniques, there is good particle/matrix phase capacitive, eliminate wedge angle stress concentrate etc. advantage, make aluminum matrix composite while possessing high strength, high-modulus, there is the combination property of a series of excellence such as good toughness, plasticity and antifatigue, creep resistant, high damping, low bulk, and directly can carry out conventional casting, machine cut, welding and deformation processing.
The tungsten carbide hard alloy coating that backing surface layer 2 is prepared for detonation flame spraying method, the thickness of tungsten carbide hard alloy coating is preferably 1 ~ 2mm.Tungsten carbide hard alloy coating is as the working face of liner plate, tungsten carbide hard alloy coating has good mar proof, heat resistance and thermal conductivity, prevent friction between ceramic powder and mould from producing plucking phenomenon, and the hardness of tungsten carbide hard alloy coating is higher than the hardness of ceramic powder, in the process of press mold, ceramic powder has the effect of polishing to this coating, effectively can avoid the sizing problem because surface abrasion causes.Meanwhile, the fire damage of detonation flame spraying method to matrix is little, can not produce distortion and phase transformation; The thickness of coating easily controls, and allowance is little, and maintenance operation is convenient; In spraying process, tungsten carbide and tungsten carbide-base dusty material can not produce carbon and decompose and decarburization phenomenon, thus can ensure the uniformity of coating structure composition and powdered ingredients.When tungsten carbide hard alloy coating may wear to a certain degree, by detonation flame spraying method, liner plate is repaired, easy to operate.
In order to strengthen the shock resistance of liner plate and be convenient to installation and maintenance, liner plate matrix 1 offers screwed hole 3, be convenient to liner plate and coordinate with mould and install.
Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, and these distortion and change include within protection domain of the present utility model.
