Abstract

A kind of diamond nozzle, the nozzle that particularly a kind of sandblast or shot blasting equipment are used.In the nozzle that common powdered metallurgical material is made, embedded superhard materials such as diamond, the wearability of nozzle is obviously improved,, reduced cost, boosted productivity to reduce nozzle consumption.Can produce in surface treatment and big petrochemical industry, shipbuilding, casting and other the mechanical industries of removing surface workload than the large economy benefit.

Description

The present invention relates to a kind of nozzle, the nozzle that particularly a kind of sandblast or shot blasting equipment are used.
Be unable to do without sandblast and shot blasting equipment in metal material surface processing and the cast(ing) surface scale removal process.Nozzle in this equipment is made (comprising common ceramic material in the said powdered metallurgical material) by powdered metallurgical material (as boron carbide, boron nitride, titanium carbide and alundum (Al etc.).Because blasting materials hardness height, so the consumption of nozzle is quite surprising, the frequent nozzle of changing makes productivity ratio reduce again in the use, and production cost improves.
Task of the present invention is: develop a kind of nozzle with high-wearing feature, by improving the consumption that reduces nozzle service life of nozzle, reduce production costs, boost productivity.
Task of the present invention is to adopt following scheme to realize: embed the superhard material of high rigidity, high-wearing feature in the nozzle of powdered metallurgical material, as diamond or cubic boron nitride etc., utilize powder metallurgy process machine-shaping.The bag embedding wearability of nozzle of superhard material obviously improve, if control as the hardness of the powdered metallurgical material of matrix at H RCBetween the 40-80, can obtain better result of use.
The present invention is applied to can further reduce product cost in the nozzle of segment type structure.
Details of the present invention is by providing in following examples and the accompanying drawing.
The structure of nozzle figure that accompanying drawing proposes for the present invention.See Fig. 1. Fig. 2.
Adopted diamond as superhard material in this example, diamond polycrystal (2) and monocrystal (1) are by powdered metallurgical material (3) embedding of wrapping as matrix.Diamond polycrystal (2) is in the tight in the form of a ring spread pattern of nozzle inner surface.Nozzle among the embodiment is to adopt pressure sintering machine-shaping.In view of the segment type structure helps reducing product cost, this example has adopted the segment type structure.Hardness as the powdered metallurgical material (3) of matrix in this example is controlled in H RCBetween the 40-80, have a better effect: the common nozzle of sand spraying machine life-span as a comparison is 0.5~1 hour, the diamond nozzle life that similarity condition uses down surpasses 6 hours, and the life-span has been plain nozzle more than 6 times, but also potential further raising.
The present invention improves the service life of nozzle greatly, production cost is obviously reduced, reduced the replacing number of times of nozzle, improved production efficiency, big in surface treatment or removing surface workload, sandblast, shot blasting equipment use many petrochemical industry, shipbuilding, casting and other machinery industries can produce bigger economic benefit.
