Description
[technical field]
The invention belongs to surface-coated guard technology, relate to aero-engine and gas turbine engine component shielded area spraying institute
A kind of frock needed, a kind of spraying bounce-back frock for shielded area.
[background technology]
The raising required along with aero-engine performance, the quantity of various accurate complex components progressively increases, and its structure
Also become increasingly complex.This patent for there is the precision of shielded area, complex parts surface needs to be coated technique and designs
A kind of frock.
Frequently with compressed air as granule driving force in spraying process, thus granule reversely launch or splashing effect is past
Toward the waste and the pollution of operation room environment that cause powder.Simultaneously as piece surface has the structure spy such as groove, flat shape face
The defects such as point, easily causes piece surface drain spray, coating binding force difference occur.
[summary of the invention]
It is an object of the invention to solve the problems referred to above, it is provided that a kind of spraying bounce-back frock for shielded area.
For reaching above-mentioned purpose, the present invention is achieved by the following technical solutions:
A kind of spraying bounce-back frock for shielded area, including base and bounce-back rubber；Bounce-back rubber is installed on base
Upper surface, and bounce-back rubber upper surface distance spray-coating surface vertical dimension be 5～7mm.
The present invention is further improved by:
Described bounce-back rubber is fixed by screws on base, and base offers internal thread hole, corresponding on bounce-back rubber
Through hole is offered in position, and screw is stretched into by through hole, and its external screw thread coordinates with internal thread hole, is fixed with base by bounce-back rubber.
Described bounce-back rubber is fixed with base by least two screw.
Bounce-back particle flux is not disturbed in the position of the screwed hole on described base.
The shape and size of described bounce-back rubber are identical with the shape of part shielded area and base.
Described bounce-back rubber uses heat-resistant silicon rubber, and heat resisting temperature is 180～220 DEG C.
The thickness of described bounce-back rubber is 2-3mm.
Compared with prior art, the method have the advantages that
Present configuration is simple, low cost, making, easy accessibility；Can according to part difformity and be sized to
The bounce-back frock of its coupling, applied widely；It is strong that bounce-back rubber impact hits ability, be hardly damaged, ageing resistance good, paste with part
Close good；The high resiliency of rubber can be avoided particle deposition and adhere to, and frock repeat usage is high, need not clear up, environment friendly and pollution-free；
After spraying, silastic surface deposits almost without granule, follow-up maintenance easy maintenance；Frock makes full use of bounce-back caoutchouc elasticity structure
Feature, can realize the preparation of Special-Shaped Surface coating, and the quality of part shielded area coating has been effectively ensured.
[accompanying drawing explanation]
Fig. 1 is the overall structure schematic diagram of the present invention；
Fig. 2 is the structural representation that the present invention is applied to ring-shaped work pieces.
Wherein, 1-base；2-rebounds rubber；3-screw.
[detailed description of the invention]
Below in conjunction with the accompanying drawings the present invention is described in further detail:
Seeing Fig. 1, the present invention spraying bounce-back frock for shielded area, including base 1, bounce-back rubber 2, screw 3.Base
Depending on the shape of 1 and size are according to concrete part, it is desirable to coupling is firm, it is impossible to relative motion occurs, and the height of base 1 is necessary
After ensureing itself and bounce-back rubber 2 combination, the vertical dimension of bounce-back rubber rebound surface distance spray-coating surface meets 5-7mm.For shape
Complicated loop-like part etc., can carry out segment design by base, i.e. ensures the convenient dismounting again of base Fast Installation, improves part
Spray efficiency.Designing screwed hole, screwed hole size and quantity on base 1 to determine according to accessory size size, screwed hole is used for pacifying
Cartridge screw 3, connects base 1 and bounce-back rubber 2, should be advisable not disturb bounce-back particle flux in the position of screwed hole.Bounce-back rubber 2 is adopted
With the bigger heat-resistant silicon rubber of elastic modelling quantity, heat resisting temperature is 180～220 DEG C.According to part shielded area and base shape, cutting
Become corresponding shape and size.For complex-shaped irregular part, bounce-back rubber can be split into a few part, be combined
Assembling.Position processing through hole corresponding with base threaded hole on bounce-back rubber, is fixed on base 1 by screw by bounce-back rubber
On.Screw 3 is external screw thread, for firm banking 1 and bounce-back rubber 2.After fixing first, follow-up without fixedly mounting again, can be straight
Connect use.
Embodiment:
As in figure 2 it is shown, for following bounce-back frock can be used in ring-shaped work pieces narrow regions to carry out the spraying of shielded area, this
The shape of base 1 of invention may be designed as annular, is divided into three sections, and each section is arc profile as shown in Figure 2, and angle is
120 °, after the height of base 1 ensures itself and bounce-back rubber 2 combination, the rubber rebound surface vertical dimension away from spray-coating surface is left at 5-7mm
Right.Bounce-back rubber 2 uses the heat-resistant silicon rubber that elastic modelling quantity is bigger to make, and heat resisting temperature is 180～220 DEG C.Will bounce-back rubber 2
It is cut into the shape identical with base 1 axial surface.The bounce-back rubber of the equal supporting one piece of respective shapes of cutting on each section of base
2.Screwed hole at 3, screwed hole size and position is designed not disturb bounce-back particle flux to be advisable, by screw 3 through bounce-back on base 1
Rubber 2 is screwed in the screwed hole on base 1 and makes bounce-back rubber 2 be fixed on base 1 surface.Then bounce-back frock combination completed
Load part spraying opposite, can spray.
The principle of the present invention:
The present invention uses rubber frock, utilizes " light line reflection " principle, when sprayed particle " clashes into " rubber with certain kinetic energy
Behind glue surface, there is elastic-plastic deformation in rubber due to the resilient characteristic of himself, will spray while it recovers original deformation
It is coated with the piece surface of particle bounce extremely required spraying.The granule kinetic energy rejection reversely ejected is little, almost without loss, and the only side of moving
To there occurs change.By the regulation and control to angle of gun and jet length etc., realize part gap, each corner and parallel surface with this
Etc. the spraying of shielded area so that part shielded area or Special-Shaped Surface can obtain the coating meeting a performance requirement.
Above content is only the technological thought that the present invention is described, it is impossible to limit protection scope of the present invention with this, every presses
The technological thought proposed according to the present invention, any change done on the basis of technical scheme, each fall within claims of the present invention
Protection domain within.
