Description
Technical field
The present invention relates to shot peening device field, particularly for the ball stream restraint device of shot peening.
Background technology
Shot peening strengthening is in the state of being controlled completely at one, countless small circular shots high speed and continuous injection to be beaten
To piece surface so as to produce a metal material cold-treating process for residual compressive stress layer in piece surface, part is reduced tired
Labor, improves one of the effective ways in life-span.During blade processing, can run into only needs to spray the tenon position of blade
The situation of ball intensive treatment, and do not allow to carry out blade profile extra protection during shot peening, therefore
It is accomplished by rationally controlling the sputter area of shot-peening during the shot peening to blade tenon so that shot-peening is as little as possible
It is splashed on the type of blade face position.In order to solve the above problems, trial carries out shot peening using small-bore spray gun,
But carry out the phenomenon that shot-peening pellet is blocked in shot-peening flexible pipe occur during shot peening using small-bore spray gun, thus
Shot peening normally cannot be carried out to blade.
The content of the invention
Regarding to the issue above, the invention provides the ball stream restraint device for shot peening, it can be to blade
The effectively sputter area of control shot-peening is carried out during shot peening, shot-peening is reduced to not needing the blade type of bead
The influence in face, meets the overall roughness requirements of blade.
For the ball stream restraint device of shot peening, it is characterised in that：It includes spray gun adapter sleeve and baffle plate, described
Spray gun adapter sleeve center hollows out to form spray gun mounting groove, and the bottom land of the spray gun mounting groove is further opened with pacifying with the spray gun
The concentric through hole of tankage, the spray gun mounting groove is installed in the front end of compressed air shotblasting machine spray gun, is provided with the baffle plate and is passed through with described
The concentric shot-peening spray-hole of through hole, connects between the spray gun adapter sleeve and the baffle plate by the way that connecting rod level is concentric, and
The connecting rod is located at the outside of the through hole.
It is further characterized by：
The medial surface of the baffle plate is also equipped with rubber peel；
Area of the area of the rubber peel more than the baffle plate medial surface；
It is fastenedly connected by the trip bolt of radial direction between the compressed air shotblasting machine spray gun and the spray gun adapter sleeve.
It is further characterised by：
The baffle plate includes the big baffle plate in outside and inner side small front apron, and the big baffle plate in outside is provided with installation through-hole, described interior
The lateral surface of side small front apron is provided with lug boss, and the lug boss is chimeric to be installed in the installation through-hole, the small gear in inner side
Plate is provided with the shot-peening spray-hole concentric with the installation through-hole of the big baffle plate in the outside, and the lug boss of the inner side small front apron is opened
There are the expansion through hole concentric with the shot-peening spray-hole, the internal diameter of the internal diameter more than the shot-peening spray-hole of the expansion through hole；
Connected by the way that the connecting rod level is concentric between the spray gun adapter sleeve and the big baffle plate in the outside, and it is described
Connecting rod is located at the side face outside of the inner side small front apron；
The rubber peel is arranged at the medial surface of the big baffle plate in the outside and positioned at the inner side small front apron outer circumferential side.
The beneficial effects of the present invention are：
（1）In on compressed air shotblasting machine spray gun, the pellet sprayed from spray gun needs to be sprayed by the shot-peening on baffle plate for its integral installation
Blade surface can be just sprayed to behind hole, and the shot-peening for being introduced into shot-peening spray-hole then cannot spray to leaf by the inner surface stop of baffle plate
Piece surface, thus baffle plate can play a part of to effectively reduce shot-peening sputter area；And it is arranged at the rubber peel energy of baffle plate medial surface
Enough shot-peenings to being introduced into shot-peening spray-hole play further buffering and rebound effect, and the particularly area of rubber peel is more than baffle plate
The area of medial surface, can more effectively reduce shot-peening sputter area, so as to meet the integral surface roughness requirements of blade；
（2）Its baffle plate is made up of the big baffle plate in outside and inner side small front apron, and the lug boss of inner side small front apron is fitted together to one heart to be installed
In on the big baffle plate in outside, the shot-peening sprayed by compressed air shotblasting machine spray gun is via the big baffle plate of the shot-peening spray-hole of inner side small front apron and outside
On expansion through hole after spray to blade, the medial surface of the big baffle plate of the medial surface of inner side small front apron and outside can be to being introduced into spray
The shot-peening of ball spray-hole plays barrier effect, so as to effectively reduce the sputter area of shot-peening, simultaneously because baffle plate employs outside
The form that big baffle plate is assembled with inner side small front apron overlapping, so as to effectively increase the shot-peening barrier zones around shot-peening spray-hole
Thickness, it is ensured that the baffle plate in the region will not deform or even breakdown under the effect of impact of a large amount of shot-peenings, and then meet blade
Integral surface roughness requirements after shot-peening reinforcement treatment.
