Description
Technical field
The present invention relates to the manufacturing technology of automobile stabilizer bar more particularly to the inner-wall reinforced techniques of hollow stabilizing rod.
Background technology
Stabiliser bar is an important part in automobile suspension system, its effect is to prevent vehicle body from occurring in turning
Big lateral inclination, so as to improve comfort by bus.With enhancing of the automobile industry to environmental protection and energy-saving and emission-reduction requirement, automobile
It is also higher and higher to light-weighted requirement, there are more and more automobiles to have begun using hollow stabilizing rod.
In order to improve the fatigue life of stabiliser bar, generally there is the step of outer surface ball blast during stabiliser bar is manufactured
Suddenly, in order to the stress of stably dispersing rod outer surface and the corrosion of clear outer surface.However for hollow stabilizing rod and
Speech, the intensive treatment for only carrying out stabiliser bar outer wall is inadequate, it is necessary to it is also contemplated that carrying out intensive treatment to stabiliser bar inner wall.
Invention content
The technical problems to be solved by the invention are to provide a kind of surface quality for improving hollow stabilizing rod inner wall, improve
The inner-wall reinforced method of hollow stabilizing rod of hollow stabilizing rod inner wall fatigue resistance.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：
A kind of inner-wall reinforced method of hollow stabilizing rod, includes the following steps：
A, pellet is put into hollow stabilizing rod, then seals the nozzle at hollow stabilizing rod both ends；
B, hollow stabilizing rod is obliquely located in high frequency vibrating motivation, concentrates on the pellet inside hollow stabilizing rod hollow steady
The high stress areas of fixed pole one end；
C, start high frequency vibrating motivation, high-frequency vibration is carried out to hollow stabilizing rod, is shut down after preset time of vibration t1；
D, the hollow stabilizing rod in high frequency vibrating motivation is repositioned, the pellet inside hollow stabilizing rod is made to concentrate on hollow stabilization
The high stress areas of the bar other end；
E, high frequency vibrating motivation is again started up, high-frequency vibration is carried out, and after preset time of vibration t2 to hollow stabilizing rod
It shuts down.
After adopting the above technical scheme, the present invention has at least the following advantages：
The present invention is by by hollow stabilizing rod high-frequency vibration so that the pellet for being collected at hollow stabilizing rod inner wall high stress areas touches
It hits, rub, impact inner wall surface, so as to generate beneficial residual compressive stress in inner wall high stress areas and improve inner wall quality,
So as to improve the fatigue resistance of hollow stabilizing rod inner wall, the service life of hollow stabilizing rod is extended.
Description of the drawings
Fig. 1 is the flow diagram of the inner-wall reinforced method of hollow stabilizing rod according to an embodiment of the invention.
Fig. 2, Fig. 3 and Fig. 4 show the schematic diagram of inner-wall reinforced process according to an embodiment of the invention.
Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
It please refers to Fig.1.The manufacturing process of a kind of high stress hollow stabilizing rod according to an embodiment of the invention, including following
Step：
Step a, pellet is put into hollow stabilizing rod, then seals the nozzle at hollow stabilizing rod both ends.In the present embodiment, such as
It is the both ends that hollow stabilizing rod 1 is respectively fitted over using a pair of socks 2, so as to seal the pipe at hollow stabilizing rod both ends shown in Fig. 2
Mouthful.The pellet 3 being placed in hollow stabilizing rod 1 is also shown in Fig. 2.Pellet 3 can be shot, ceramic pellet or glass ball.
Step b, as shown in Figure 3.Hollow stabilizing rod 1 is obliquely located in high frequency vibrating motivation（It is not shown in figure）On, make
Pellet 3 inside hollow stabilizing rod 1 concentrates on the high stress areas of hollow stabilizing rod one end.In the present embodiment, high stress areas
By the mobile jib body 11 of hollow stabilizing rod and the boundary bending part 13 in lateral bending portion 12 and near 13 both sides of boundary bending part
Region is formed.
Step c, start high frequency vibrating motivation, high-frequency vibration is carried out to hollow stabilizing rod, after preset time of vibration t1
It shuts down.
Step d, as shown in Figure 4.Hollow stabilizing rod 1 in high frequency vibrating motivation is repositioned, is made inside hollow stabilizing rod 1
Pellet 3 concentrate on the high stress areas of the hollow stabilizing rod other end.
Step e, high frequency vibrating motivation is again started up, high-frequency vibration is carried out to hollow stabilizing rod, and passing through preset vibration
It is shut down after time t2.
Vibration frequency f >=20Hz of high-frequency vibration described in the present embodiment.Preset vibration described in the present embodiment
The value range of time t1 and preset time of vibration t2 are 3~10 minutes, and t1 and t2 can be equal, can not also wait.
Step f, the protective case at hollow stabilizing rod both ends is removed, recycles pellet.
The present invention is by by hollow stabilizing rod high-frequency vibration so that is collected at the ball of hollow stabilizing rod inner wall high stress areas
Grain collision, friction, impact inner wall surface, so as to generate beneficial residual compressive stress in inner wall high stress areas and improve inner wall matter
Amount, so as to improve the fatigue resistance of hollow stabilizing rod inner wall, extends the service life of hollow stabilizing rod.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
