Description
Technical field
The utility model is related to field of surface engineering technique more particularly to a kind of telescopic hollow cone abrator heads.
Background technology
Blasting craft metal surface brushing technical field needs before the brushing paint of metal surface to carry out sandblasting polishing pretreatment, with
Anvil cinder existing for removal metal surface and sand holes protrusion and the roughness for changing metal surface, roughness is controlled in certain model
It encloses.The change of Metal Surface Roughness causes metal surface to enhance during brushing paint the adhesion of coating, is not easy to flow
It hangs, applies brushing effects enhancing.Existing sand blasting unit nozzle is direct injection on the market, and spray angle is smaller, suitable for metal device
The sandblasting polishing of outer surface, but it is poor for the sandblasting polishing effect of different shape metal device inner wall, tube bank inner wall.For interior
Cavity space is small, and into the structure polishing for surrounding shape, existing sand blasting unit polishing has the easily long-pending sand in uneven thickness, dead angle of polishing, spray
The problem of firing angle degree is small low with sandblasting efficiency.
Utility model content
There is the easily long-pending sand in uneven thickness, dead angle of polishing, injection for existing sand blasting unit sandblasting polishing in the utility model
The problem of angle is small low with sandblasting efficiency provides a kind of telescopic hollow cone abrator head.
The technical solution that the utility model solves above-mentioned technical problem is as follows：
A kind of telescopic hollow cone abrator head, including nozzle, telescopic rod, diffusion tip and blast tube, which is characterized in that described
Nozzle is cone, and bottom surface is the spherical surface of indent, and bottom edge is fixedly connected with the sandblasting inside pipe wall, axle center with it is described
Blast tube center line overlap；Described telescopic rod one end is fixed on the vertex of the nozzle, and parallel with the axis of the nozzle,
The diffusion tip is cone, and the telescopic rod other end is pierced by from the diffusion tip vertex to plane perpendicular, is pierced by part and sets
There is nut.
Further, the diffusion tip side is hyperboloid or circular conical surface.
Further, the blast tube draw ratio is 10-15.
Further, the diffusion tip material is one kind in antifriction metal (AFM), ceramics or elastic wear-resisting rubber.Wear-resisting gold
Belong to and potassium steel, chrome alloy cast iron and high carbon complex alloy steel etc. can be selected, the optional silicon carbide ceramics of ceramics or aluminium oxide
Ceramics.
Nozzle may be used with telescopic rod and be welded to connect, and can also be connected by the way of integrated pressure injection, extruding or casting
It connects.
The beneficial effects of the utility model are：The utility model is designed using inner spray nozzle, is configured in blast tube exit
Adjustable tapered diffusion tip forms hollow cone sandblasting stream, sandblasting stream is made equably to spread apart, and reduces the close of central area sandblasting
Degree, strengthens the diffusion effect of sandblasting, increases sandblasting face, and to the polishing of metal evenly, grinding efficiency is also promoted.Spray
Mouth center is adjustment bar, carries out different location adjustment to diffusion tip by adjusting bar and nut, obtains different tapered injection sand flows,
It can polish the sandblasting of different-grain diameter and the metal device sandblasting of non-co-content, realize best sandblasting polishing effect.Diffusion
The conical surface of head is curved design, is bonded sandblasting flow trace, reduces impact of the sandblasting to diffusion tip.
