Abstract
The utility model discloses a PCD integrated nozzle for a water-jet-cutter cutting machine. The PCD integrated nozzle comprises a hard alloy base body and a polycrystalline diamond compact layer. The hard alloy base body is in a circular-truncated-cone shape, the polycrystalline diamond compact layer is arranged on the large end face of the hard alloy base body, a water passing hole is formed in the middle of the polycrystalline diamond compact layer, a water outlet hole communicated with the water passing hole is formed in the middle of the hard alloy base body, and the diameter of the water passing hole is smaller than the diameter of the water outlet hole. The PCD integrated nozzle is simple in structure and good in centering performance; when being used, the PCD integrated nozzle is matched with a cutting head of the water-jet-cutter cutting machine, the high concentricity is achieved, the hard alloy base body has the supporting effect, and the polycrystalline diamond compact layer mainly has the abrasion resisting effect; in the working process of a water jet cutter, water at the ultrahigh pressure is jetted out at a high speed through the water passing hole, and due to the fact that diamond has the excellent abrasion resistance and is resistant to scouring of high-pressure water flow, the service life of the nozzle can be effectively prolonged.
Description
Technical field
The utility model belongs to superhard material applied technical field, particularly PCD one nozzle for a kind of water-jet cutting machine.
Background technology
At present, the cutting of water cutter is a kind of cold cut segmentation method with fastest developing speed in recent years, and it is to utilize high-pressure water as cutting tool, and high-pressure water flows out fast the high-pressure water jet forming workpiece is cut from nozzle.Because the pressure of the high-pressure water of water-jet cutting machine is 30MPa～600MPa, and high-pressure water ejection fast from nozzle, thereby require the nozzle can be high pressure resistant, wear-resisting.But, the defect that the nozzle using now exists and wears no resistance, centering is poor, shorter in washing away in the lower service life of high-pressure water, use cost is high.
Utility model content
The utility model provide a kind of simple in structure, centering good and the water-jet cutting machine of long service life PCD one nozzle.
For achieving the above object, the technical solution of the utility model is: PCD one nozzle for a kind of water-jet cutting machine, comprise hard alloy substrate and dimond synneusis compact layer, hard alloy substrate is truncated cone-shaped, and dimond synneusis compact layer is arranged on the large end face of hard alloy substrate; Dimond synneusis compact layer middle part is provided with water hole, and hard alloy substrate middle part is provided with the apopore communicating with water hole, and water hole diameter is less than apopore diameter.
The cone angle of described hard alloy substrate is 30 °～60 °.
Described water hole and apopore coaxially arrange, and the water side of apopore is provided with horn mouth, and bell-mouthed large mouthful is positioned on hard alloy substrate small end face.
The thickness of described dimond synneusis compact layer is 1～4mm.
Compared with prior art, the utility model has the advantages that: the utility model comprises hard alloy substrate and dimond synneusis compact layer, hard alloy substrate is truncated cone-shaped, and dimond synneusis compact layer is arranged on the large end face of hard alloy substrate; Dimond synneusis compact layer middle part is provided with water hole, hard alloy substrate middle part is provided with the apopore communicating with water hole, water hole diameter is less than apopore diameter, it is simple in structure, and centering is good, when use, match with the cutting head of water-jet cutting machine, have high concentricity, hard alloy substrate plays a supportive role, and dimond synneusis compact layer mainly plays wear-resisting effect; In the water cutter course of work, high-pressure water is through water hole ejection at a high speed, and because diamond has good anti-wear performance, high pressure resistant current scour, can make the life-span of nozzle effectively be extended.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
PCD one nozzle for water-jet cutting machine as depicted in figs. 1 and 2, it comprises hard alloy substrate 1 and dimond synneusis compact layer 2, hard alloy substrate 1 is that cone angle is the truncated cone-shaped of 30 °～60 °, dimond synneusis compact layer 2 is arranged on the large end face of hard alloy substrate 1, and the thickness of dimond synneusis compact layer 2 is 1～4mm.Be provided with water hole 5 at dimond synneusis compact layer 2 middle parts, hard alloy substrate 1 middle part is provided with the apopore 3 communicating with water hole 5, and water hole 5 coaxially arranges with apopore 3, and the diameter of water hole 5 is less than the diameter of apopore 3.Be provided with horn mouth 4 in the water side of apopore 3, large mouthful of horn mouth 4 is positioned on the small end face of hard alloy substrate 1.
In the present embodiment, dimond synneusis compact layer 2 forms through grinding and punching, and its thickness is 2mm, and the granularity of dimond synneusis compact layer 2 is Monosized powder or combination grain; The cone angle of hard alloy substrate 1 is 50 °.
When use, the utility model matches with the cutting head of water-jet cutting machine, has high concentricity, and centring property is good, and hard alloy substrate 1 plays a supportive role, and dimond synneusis compact layer 2 mainly plays wear-resisting effect.In the water cutter course of work, high-pressure water is through water hole 5 ejection at a high speed, and because diamond has good anti-wear performance, high pressure resistant current scour, can make the life-span of nozzle effectively be extended.
