Description
Technical field
The utility model belongs to the spray gun fittings technical field, relates to a kind of wear-resisting spray tip, and upper kettle rifle, lower kettle rifle, side kettle rifle or automatic gun are all applicable.
Background technology
Spray gun is generally that it comprises the body of a gun, rifle head by material spray being sprayed to the instrument of device surface under certain pressure, and this body of a gun is connected by a bindiny mechanism with the rifle head; This rifle head comprises a nozzle, and this nozzle interior plug welding has some metal round steels; Bindiny mechanism comprises flange and chain pin, and nozzle manufactures flat.
In prior art, no matter be manual spray gun or automatic spray gun, nozzle is nearly all to adopt stainless steel material, and spray gun uses half a year to one year, and nozzle will wear and leakage, and spray gun damages, and whole nozzle all needs to be changed.If a kind of nozzle can be arranged, split into rifle pin and nozzle head, and adopt high hardness material, wear prevention and leakage, just can lengthen service life of spray gun greatly, greatly reduce costs, in the spray gun fittings technical field, will be a revolutionary innovation.
Summary of the invention
No matter the utility model, in prior art, is manual spray gun or automatic spray gun, and nozzle is nearly all to adopt stainless steel material, spray gun uses half a year to one year, nozzle will wear and leakage, and spray gun damages, and whole nozzle all needs the defect of being changed, a kind of spray tip is provided, split into rifle pin and nozzle head, and adopt high hardness material, wear prevention and leakage, just can greatly lengthen the service life of spray gun, greatly reduce costs.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of wear-resisting spray tip, comprise rifle pin and nozzle head, and the head end of rifle pin is located in nozzle head, and the bore of nozzle head is 1～10mm.In prior art, mouth is integrative-structure, can only whole nozzle exchange after damage, and cost is high, and whole nozzle difficulty of processing is large, the precision deficiency, easily wear and tear and the generation leakage while causing nozzle to use, reduce the service life of spray gun, so form vicious circle, be difficult to solve.Spray tip in the utility model, splitting into two structural members of rifle pin and nozzle head is assembled, except independent processing greatly reduces difficulty of processing, guarantee high accuracy, make nozzle more wear-resisting, outside preventing from revealing, also only need to change the rifle pin during replacing, nozzle head can be reused, and more saves cost.
As preferably, the material of rifle pin and nozzle head is glass hard steel or high-hardness ceramic.Wolfram steel (carbide alloy) has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, particularly its high rigidity and wearability, even also substantially remain unchanged, still have very high hardness in the time of 1000 ℃ at the temperature of 500 ℃.Wolfram steel belongs to carbide alloy, is referred to as again tungsten-titanium alloy.Hardness can reach 89～95HRA, and just because of this, the product of wolfram steel (common are the wolfram steel wrist-watch), have and be difficult for being worn, hard characteristic of not being afraid of annealing.The pottery that Rockwell hardness is HRA80-90, hardness is only second to diamond, considerably beyond abrasion-resistant stee and stainless anti-wear performance, becomes wear-resistant ceramic.Wear-resistant ceramic is to take aluminium oxide as primary raw material, take rare metal oxide as flux, the extraordinary corundum ceramic formed through 1,700 degree high-temperature roastings, then the product formed by specific rubber and high-intensity organic/inorganic binder combination respectively.Except hardness is large, and also there is the characteristic that anti-wear performance is fabulous, lightweight, bonding firmly, heat resistance is good, its wearability is equivalent to 266 times of manganese steel, 171.5 times of rich chromium cast iron.Under equal operating mode, at least extension device service life is more than ten times, density is 3.6-3.9g/cm3, be only half of iron and steel, can greatly alleviate machine utilization, the mill potsherd preferably adopts the high-strength ceramic structure glue to paste, and can guarantee that at high temperature operation for a long time of pottery does not come off, and can move for a long time not aging under 350 ℃.
As preferably, the material of rifle pin and nozzle head is the pottery that steel that Rockwell hardness is HRC40～65, wolfram steel that hardness is HRC89～93 or hardness are HRC80～90.High rigidity and high-wearing feature be Leakage prevention effectively, greatly the service life of prolonging nozzle, from the 0.5-1 of prior art, extends to 7-8, easy to maintenance.
As preferably, more than rifle pin and nozzle head surface treatment all reach HRC40.
As preferably, there is inclined-plane the nozzle head inboard, and the rifle pin is provided with the conical surface matched with inclined-plane.Effective Leakage prevention.
As preferably, between inclined-plane and the conical surface, be sealed and matched.More effectively Leakage prevention is sealed and matched.
As preferably, nozzle head is connected to nozzle body by the nozzle headstock.
As preferably, the material of nozzle headstock is copper or stainless steel.
The utility model provides a kind of wear-resisting spray tip, splits into rifle pin and nozzle head, and adopts high hardness material, wear prevention and leakage, just can greatly lengthen the service life of spray gun, greatly reduce costs, overcome in prior art, no matter be manual spray gun or automatic spray gun, nozzle is nearly all to adopt stainless steel material, and spray gun uses half a year to one year, and nozzle will wear and leakage, spray gun damages, and whole nozzle all needs the defect of being changed.The utility model will have a good application prospect in the spray gun fittings technical field.
