Abstract
The utility model provides a superhard material sand mixing pipe. The superhard material pipe is inlaid inside a metal pipe, and provided with a through hole; and a horn mouth is formed in the inlet part of the sand mixing pipe. The metal pipe can be made of steel, alloy steel, a hard alloy and the like; and the superhard material pipe can be made of a diamond glomerocryst, a natural diamond, an artificial diamond, a CVD (Chemical Vapor Deposition) diamond, a CVD diamond coating or cubic boron nitride, so that the superhard material sand mixing pipe is formed. The superhard material sand mixing pipe overcomes the shortcoming that the existing superhard material sand mixing pipe is incapable of meeting the actual requirement of water cutting. The superhard material sand mixing pipe provided by the utility model is capable of meeting the actual requirement of water-jet cutting, and the service life of the superhard material sand mixing pipe is more than ten and even dozens of times longer than the service life of a hard alloy sand mixing pipe.
Description
Technical field
The utility model relates to a kind of superhard material mulling pipe, belongs to superhard material technology, water jet cutting technique field.
Background technology
When using water jet to carry out cutting processing; use the power that pomegranate sand strengthens water jet through regular meeting; so just must use the mulling pipe; English name: Abrasive Nozzle; present mulling pipe is that material is made with the high-anti-friction hard alloy, penetrates the back through the water after the supercharging of high-pressure water-jet cutting machine tool equipment booster at a high speed by jewel nozzles and strengthens cutting effect by husky mixing of mulling pipe and abrasive material.The mulling pipe is the most critical part of water cutting, reach good cutting effect, do not disperse the high speed water sand drift that ejects in the mulling pipe must gather, the water cutter has determined the high standard parasexuality of its material and technology for the high concentricity of endoporus, best bright finish, the high-wearing feature of sandpipe.Carbide alloy mulling pipe normal service life is 100 hours, is difficult to satisfy the actual needs of water jet cutting.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides a kind of superhard material mulling pipe, a kind of superhard material mulling pipe that can be improved tens times even tens times the service life of mulling pipe.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of superhard material mulling pipe, and the superhard material pipe is embedded in metal tube inside, and the superhard material pipe has through hole, and the mulling tube inlet partly has horn mouth.
The superhard material pipe of mulling pipe exit portion and the syndeton of metal tube are seam, are threaded or directly welding.
The superhard material pipe of mulling tube inlet part and the syndeton form of metal tube are threaded or directly weld.
Be connected to hot edge, welding or high temperature sintering between metal tube and the superhard material pipe.
The external diameter of superhard material pipe and the internal diameter of metal tube have tolerance fit.Adopt methods such as hot edge, welding, high temperature sintering that metal tube and superhard material pipe are linked together.
The beneficial effects of the utility model: because the high-wearing feature of superhard material, the superhard material mulling pipe of making has long service life, advantage that comprehensive benefit is good, than the life-span that present carbide alloy mulling pipe improves tens times even tens times, satisfy the actual needs of water jet cutting.
Description of drawings
When considered in conjunction with the accompanying drawings, by the reference following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide further understanding of the present utility model, constitute a part of the present utility model, illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute to improper restriction of the present utility model, wherein:
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 1.
Below in conjunction with drawings and Examples the utility model is further specified.
The specific embodiment
Obviously, the many modifications and variations done based on aim of the present utility model of those skilled in the art belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, superhard material pipe 2 is embedded in metal tube 1 inside, and superhard material 2 has through hole, and the mulling tube inlet partly has horn mouth 3.
Embodiment 2: as shown in Figure 2, the superhard material pipe 2 of mulling pipe exit portion and the syndeton form of metal tube 1 have seam, be threaded or directly welding etc.
Embodiment 3: as shown in Figure 3, and the superhard material pipe 2 of mulling tube inlet part and the syndeton form of metal tube 1 is threaded or directly welding etc.
Embodiment 4: a kind of superhard material mulling pipe studs with superhard material pipe 2 in metal tube 1; Described metal tube 1 can be steel, steel alloy or carbide alloy etc.;
Described superhard material pipe 2 can be dimond synneusis, natural diamond, diamond, CVD diamond, CVD diamond coatings or cubic boron nitride.
Syndeton form between metal tube 1 and the superhard material pipe 2 can have multiple mode, and metal tube 1 plays protection and supporting role outside, has through hole to play effect wear-resisting, the polymerization mixed flow in the middle of the superhard material pipe 2.
The methods such as hot edge, welding, high temperature sintering that are connected between metal tube 1 and the superhard material pipe 2.
As mentioned above, embodiment of the present utility model is explained, but as long as not breaking away from inventive point of the present utility model and effect in fact can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the present utility model.
