Abstract
The invention discloses a structure of a water jet blade. The blade expands from a back part toward a front part to form a conical body; a conical cavity gradually expanding from the back to the front is formed in the body; and a plurality of water outlets communicated with the front end of the body are formed on the bottom part of the cavity. The formation of the conical cavity in the body of the blade ensures that both the lengths of the water channels of the water outlets and the pressures of he water flows sprayed out from the water outlets are similar and that the effluent pressure of the water jet blade is uniform; the formation of the cavity promotes the formation of a reservoir in the blade, water enters the reservoir under the action of the pressure applied on a water source is buffered in the reservoir and the pressures provided by the reservoir for the water outlet are uniform, so the working performance of the blade is improved effectively; the reservoir has a bigger volume than the cylindrical cavity in the traditional blade, so the bland is casted with less material; and thus, the material cost of the use of the blade is reduced effectively and the water jet blade is more competitive in the market.
Description
Technical field
The relevant a kind of water cutter facility that stone material is polished and processed of the present invention is meant a kind of structure of water jet blade especially.
Background technology
For the process water cutter of stone surface matsurface, it need be distributed with the cutter head high speed rotary work of apopore.And cutter head is to be formed by the plurality of high voltage waterline, promptly forms a plurality of apopores on cutter head, have certain impulsive force and constitute polishing water cutter thereby utilize the water source pressurization to form the high pressure waterline, so cutter head need have certain voltage endurance capability.
Shown in the structural representation of cooperation Fig. 1, traditional cutter head is the whole cutter head 1 ' that is processed into by whole stainless steel block, carrying out apopore 12 ' again on cutter head 1 ' processes with the secondary mechanical of inlet opening 11 ', inlet opening 11 ' extends to a post chamber by the cutter head rear portion in cutter head, and each apopore 12 ' communicates with post chamber 13 ' respectively again, this shows, the water inlet 121 ' of each apopore 12 ' is to be distributed on the post chamber 13 ', then the length of each water outlet is had nothing in common with each other, post chamber 13 ' anterior hydraulic pressure must be the hydraulic pressure greater than sidepiece, will inevitably cause the hydraulic pressure of each apopore inhomogeneous, this is one of not good defective of present cutter head performance; In addition, the distributed architecture of this kind apopore 12 ' has also determined that whole cutter head 1 ' material requested is more, and two processing modes in each apopore 12 ' post chamber 13 ', also can produce more processing waste material, so the material cost height, and the complexity of secondary operations operation also is the reason place that present cutter head holds at high price.Described many defectives are demanded the dealer urgently and are improved.
Summary of the invention
The purpose of this invention is to provide a kind of cutter head hydraulic pressure and be evenly distributed, and the structure of water jet blade that decreases of whole cutter head material requested.
For achieving the above object, solution of the present invention is:
A kind of structure of water jet blade, this cutter head by the rear portion to the tapered body of anterior gradually expanded form, wherein: in body by after form the taper chamber of flaring forward, form a plurality of apopores that communicate with the body front end in the bottom of chamber.
Described taper chamber forms in response to the conical body profile, and is even to guarantee the wall thickness between body and the chamber.
After adopting such scheme, the formation of taper chamber in the cutter head body of the present invention is to guarantee that the water channel length of each apopore is close, and then the pressure of the current of each apopore ejection is also close, so makes the discharge pressure of water jet blade even; The formation of chamber herein is to have constituted the formation of reservoir in the cutter head, then the water that enters the cutter head from the water source pressurization has cushioning effect in this reservoir, supply with the isostasy of each apopore again by reservoir, and the uniformity that each water hole hydraulic pressure of its existing relatively cutter head distributes can improve 100%, so can effectively improve the service behaviour of cutter head; Moreover, cylindrical chamber volume in the existing relatively cutter head of this reservoir is big, therefore required material reduces to some extent when cutter head is cast, in addition, the structure of water jet blade of this structure is to adopt casting to form, thereby the manufacturing procedure simplification, and can utilize the stainless steel waste material to add the material that corresponding nickel element just can be used as the water jet blade moulding, therefore effectively reduce the material cost that cutter head uses, make it on market, have more competitiveness.
Description of drawings
Fig. 1 is for commonly using the cutter head structure cutaway view;
Fig. 2 is a cutter head structure cutaway view of the present invention;
Fig. 3 is a cutter head structure upward view of the present invention.
The specific embodiment
Shown in Fig. 2,3, a kind of structure of water jet blade that the present invention discloses, this cutter head by the rear portion to the tapered body 1 of anterior gradually expanded form, simultaneously in body 1 by after form the taper chamber 11 of flaring forward, this taper chamber 11 is to form in response to conical body 1 profile, and is even to guarantee the wall thickness between body 1 and the chamber 11; The a plurality of apopores 12 that communicate with body 1 front end are formed on the bottom at chamber 11, and the front end of each apopore 12 is formed with vertical correcting portion, to guarantee current direction ejection down.
The formation of chamber 11 herein is to guarantee that the water channel length of each apopore 12 is close, and then the pressure of the current of each apopore 12 ejection is also close, so makes the discharge pressure of water jet blade even; The formation of chamber 11 herein is to have constituted the formation of reservoir in the cutter head, then the water that enters the cutter head from the water source pressurization has cushioning effect in this reservoir, supply with the isostasy of each apopore 12 again by reservoir, and the uniformity that each water hole hydraulic pressure of its existing relatively cutter head distributes can improve 100%, so can effectively improve the service behaviour of cutter head; Moreover, cylindrical chamber volume in the existing relatively cutter head of this reservoir is big, therefore required material reduces to some extent when cutter head is cast, in addition, the structure of water jet blade of this structure is to adopt casting to form, thereby the manufacturing procedure simplification, and can utilize the stainless steel waste material to add the material that corresponding nickel element just can be used as the water jet blade moulding, therefore effectively reduce the material cost that cutter head uses, make it on market, have more competitiveness.
Claims (2)
1. structure of water jet blade, this cutter head, be is characterized in that to the tapered body of anterior gradually expanded form by the rear portion: in body by after form the taper chamber of flaring forward, form a plurality of apopores that communicate with the body front end in the bottom of chamber.
