Description
Technical field
The utility model relates to shot peening device field, is specially a kind of ball stream restraint device for shot peening.
Background technology
Shot peening strengthening is under a state controlled completely, by countless small circular shot at a high speed and spray continuously, beat to piece surface thus produce the metal material cold-treating process of a residual compressive stress layer at piece surface, reducing part tired, improving one of the effective ways in life-span.In blade processing process; the situation only needing the tenon position of blade to be carried out to shot peening can be run into; and do not allow to carry out extra protection to blade profile in shot peening process; therefore just need the sputter area of conservative control shot-peening in the shot peening process of blade tenon, shot-peening is splashed on the profile position of blade as little as possible.In order to solve the problem, attempt adopting small-bore spray gun to carry out shot peening, but adopt small-bore spray gun to carry out the phenomenon occurring in shot peening process that shot-peening ball material blocks at shot-peening flexible pipe, thus normally cannot carry out shot peening to blade.
Summary of the invention
For the problems referred to above, the utility model provides a kind of ball stream restraint device for shot peening, it can carry out the sputter area effectively controlling shot-peening in shot peening process to blade, reduce shot-peening to the impact of blade profile not needing bead, meet the overall roughness requirements of blade.

Be connected by described connecting rod level is concentric between described spray gun adapter sleeve with the large baffle plate in described outside, and described connecting rod is positioned at outside the side face of described inner side small front apron;
Described rubber peel is arranged at the medial surface of the large baffle plate in described outside and is positioned at described inner side small front apron outer circumferential side.
The beneficial effects of the utility model are:
(1) its integral installation is on compressed air shotblasting machine spray gun, need by just can blade surface be sprayed to after the shot-peening spray-hole baffle plate from the ball material of spray gun ejection, the shot-peening not entering shot-peening spray-hole is then stopped cannot spray to blade surface by the inner surface of baffle plate, and thus baffle plate can play the effect effectively reducing shot-peening sputter area; And the rubber peel being arranged at baffle plate medial surface can play further buffering and rebound effect to the shot-peening not entering shot-peening spray-hole, particularly the area of rubber peel is greater than the area of baffle plate medial surface, can more effectively reduce shot-peening sputter area, thus meet the integral surface roughness requirements of blade;
(2) its baffle plate is made up of the large baffle plate in outside and inner side small front apron, the lug boss of inner side small front apron is chimeric to be with one heart installed on the large baffle plate in outside, the shot-peening sprayed by compressed air shotblasting machine spray gun sprays to blade via after the expansion through hole on the large baffle plate of shot-peening spray-hole and outside of inner side small front apron, the medial surface of the large baffle plate of medial surface and outside of inner side small front apron all can play barrier effect to the shot-peening not entering shot-peening spray-hole, thus effectively reduce the sputter area of shot-peening, simultaneously because baffle plate have employed the form of the large baffle plate in outside and the superimposed assembling of inner side small front apron, thus effectively increase the thickness of the shot-peening barrier zones around shot-peening spray-hole, ensure that the baffle plate in this region can not be out of shape even breakdown under the effect of impact of a large amount of shot-peening, and then meet the rear integral surface roughness requirements of blade shot-peening reinforcement process.
