Description
Technical field
The present invention relates to ball blast technique technical field, more particularly to a kind of Shot Blasting technique.
Background technology
Ball blast is a kind of title of the process of surface treatment of mechanical aspects, and similar to sandblasting and shot-peening, its principle is electricity consumption
Machine impeller body rotates, and by the effect of centrifugal force, a ball is thrown to the surface of workpiece, the surface of workpiece is reached certain thick
Rugosity, workpiece is set to change the appearance, or the welding tension of change workpiece is compression, improves the service life of workpiece.Almost
For machinery most of fields, such as build ship, auto parts and components, aircraft components, firearms tank surface, bridge, steel construction,
Glass, steel pipe etc..
The thickness of some workpiece various pieces is different, when carrying out Shot Blasting to workpiece, because thickness is different, and throws
The parameters all same of ball processing, the ball blast effect that this results in workpiece each several part is inconsistent, so as to have impact on the thick of workpiece
Rugosity and service life.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of Shot Blasting technique, by adjusting the rotating speed of impeller head,
So as to adjust the initial velocity of pill, different pill initial velocity is used for the different various pieces of thickness in workpiece, makes workpiece
The ball blast effect of various pieces is consistent substantially, so as to extend the service life of workpiece.
In order to solve the above technical problems, technical scheme is as follows：
A kind of Shot Blasting technique, comprises the following steps：
S1：Measure the thickness of workpiece each several part；
S2：Put the workpiece in degreasing agent solution, carry out ungrease treatment, then put the workpiece in clear water, washed, then will
Workpiece is taken out, and the water of workpiece surface is blown away using compressed air, places into drying chamber and is dried, until the water content of workpiece
Less than 0.3wt%；
S3：After shot-blast apparatus is debugged, the workpiece after drying is placed in shot blast room, according to workpiece towards impeller head portion
The thickness divided, the rotating speed of impeller head is adjusted, carry out Shot Blasting, after the part ball blast terminates, workpiece is overturn, by workpiece
Another part adjusts the rotating speed of impeller head further according to the thickness of the part, carries out Shot Blasting, then incite somebody to action towards the nozzle of impeller head
Workpiece turning, until Shot Blasting is passed through in all parts of workpiece；
S4：Ball blast is cleared up the pill of workpiece surface after terminating using round brush；
S5：Workpiece is tested, check workpiece surface whether oil-free, rustless, non-scale, check workpiece surface roughness be
It is no to meet the requirements.
Technique effect:The various pieces different to thickness in workpiece carry out Shot Blasting respectively, and according to the thickness of the part
The rotating speed of degree regulation impeller head, so as to adjust the initial velocity of pill, makes the ball blast effect of workpiece various pieces be consistent substantially,
So as to extend the service life of workpiece.
Further, degreasing agent solution is previously heated to 40-65 DEG C between workpiece is put into S2.
Preceding described a kind of Shot Blasting technique, for thickness of workpiece in 4-5mm part in S3, by the rotating speed of impeller head
1500-1700r/min is adjusted to, for thickness of workpiece in 5-6mm part, the rotating speed of impeller head is adjusted to 1700-2000r/
Min, 6mm part is more than for thickness of workpiece, the rotating speed of impeller head is adjusted to 2000-3000r/min.
A kind of preceding described Shot Blasting technique, the pill of Shot Blasting uses cast steel ball in S3.
A kind of preceding described Shot Blasting technique, cast steel ball include 3 kinds of specifications, respectively particle diameter 0.8mm, particle diameter 1.0mm
With particle diameter 1.2mm.
A kind of preceding described Shot Blasting technique, particle diameter 0.8mm, particle diameter 1.0mm and particle diameter 1.2mm ratio in cast steel ball
For 2:1:1.
A kind of preceding described Shot Blasting technique, the nozzle of impeller head and the distance 200-300mm of workpiece surface in S3.
A kind of preceding described Shot Blasting technique, the angle of the injection direction and workpiece surface normal of impeller head is in S3
15°-30°。
The beneficial effects of the invention are as follows：
(1) in the present invention, first the thickness of workpiece each several part is measured, further according to the thickness of workpiece each several part, to impeller head
Rotating speed adjusted, so as to adjust the initial velocity of pill, to workpiece carry out Shot Blasting when, avoid because thickness of workpiece is small
And pill speed height causes workpiece deformation serious, also avoid due to thickness of workpiece is big and pill speed not enough causes ball blast effect poor
The problems such as, the ball blast effect of workpiece various pieces is consistent substantially, improve the shot-blasting quality of workpiece, make the use of workpiece
Life 55-60%；
(2) in the present invention, using pill of the cast steel ball as Shot Blasting, caused dust is few, and non-friable, service life
Longer, cost performance is higher, in addition, using the cast steel ball of three kinds of particle diameters, the big pill cleaning ability of particle diameter is strong, but coverage rate compared with
It is low, and particle diameter it is small pill cleaning ability it is general, but coverage rate is higher, after the pill using mixing particle diameter, not only increases ball
The cleaning ability of grain, and coverage rate is high, the efficiency of ball blast is improved 12-15%；
(3) in the present invention, between the distance of the nozzle of impeller head and workpiece surface is maintained at into 200-300mm, and impeller head
The angle of injection direction and workpiece surface normal is 15 ° -30 °, the shot that impeller head sprays is reached the ball blast effect of workpiece
Most preferably, shot-blasting quality is not only increased, and ball blast efficiency is improved 20-24%.
Embodiment
