Abstract
The present invention relates to one kind during hollow stabilizing rod is produced, closed forging technology is carried out to its termination.Mainly invented to solve the problem of during current hollow stabilizing rod manufactures, different degrees of oil leak situation occur after the forging of termination, cause the spraying effect of follow-up spraying process bad, directly affecting the service life of stabiliser bar.Take aluminum pipe, the caliber of aluminum pipe and the termination bore dia of hollow stabilizing rod are adapted, aluminum pipe is placed at the end holes of hollow stabilizing rod, aluminum pipe is set to be contacted with the end holes of hollow stabilizing rod, hollow stabilizing rod is heated using intermediate-frequency heating furnace, 700-800 DEG C are heated to, then utilizes end forging machine forging molding.Advantage is that hollow stabilizing rod inwall can be completely covered using aluminum pipe, can be very in the forging process of termination be sealed between the upper and lower wall of hollow stabilizing rod, reach the effect being completely covered, is not in oil leakage phenomenon.
Description
Technical field：
The present invention relates to one kind during hollow stabilizing rod is produced, closed forging technology is carried out to its termination.
Background technology：
Hollow stabilizing rod is that gradually a spring part of emerging automobile suspension system, its feature were automobile industry in recent years
Comfortableness by bus can be improved, reduce the amplitude that automobile rocks in automobile turning, simultaneously because it is hollow, vehicle can be mitigated
Weight so as to reduce oil consumption, reach the characteristics of not only economic but also economical.
At present there is a maximum difficult point --- termination oil leak in hollow stabilizing rod during manufacturing, the problem is present
There is different degrees of oil leak situation after termination forging on all hollow stabilizing rod manufacturing process, is mainly reflected in,
Cause the spraying effect of follow-up spraying process bad, directly affect the service life of stabiliser bar.
The content of the invention：
The technical problems to be solved by the invention are to provide a kind of forging technology closed to the progress of hollow stabilizing rod termination, utilize
The technique can ensure that hollow stabilizing rod termination is completely closed, oil-proof, and follow-up spraying process will not be impacted.
What above-mentioned purpose was realized in：Take aluminum pipe, the length of aluminum pipe is 100 ㎜, and the wall thickness of aluminum pipe is 0.2 ㎜, aluminum pipe
Caliber and the termination bore dia of hollow stabilizing rod be adapted, aluminum pipe is placed at the end holes of hollow stabilizing rod, make aluminum pipe with
The end holes contact of hollow stabilizing rod, is heated to hollow stabilizing rod using intermediate-frequency heating furnace, is heated to 700-800 DEG C, so
End forging machine forging molding is utilized afterwards.
The production process of hollow stabilizing rod：Blanking first, steel seal is printed on the raw material of selection, then workpiece is held
Workpiece, is sent in conducting furnace heats afterwards by head forging（Heating-up temperature is 960 DEG C）, the workpiece after heating is curved on curved machine
Song shaping, is then quenched in quenching tank, is tempered into tempering furnace, correction, using compressed air shotblasting machine shot-peening, is detected a flaw with defectoscope, is used
Injection machine is molded by injection ring, to spraying coating line on spray.
It is an advantage of the invention that：Hollow stabilizing rod inwall can be completely covered using aluminum pipe, forged in termination
Can be very in journey be sealed between the upper and lower wall of hollow stabilizing rod, plays filling effect, reaches the effect being completely covered,
It is not in oil leakage phenomenon.
Embodiment：
Closed forging technology is carried out to hollow stabilizing rod termination：Aluminum pipe is taken, the length of aluminum pipe is 100 ㎜, and the wall thickness of aluminum pipe is
0.2 ㎜, the caliber of aluminum pipe and the termination bore dia of hollow stabilizing rod are adapted, and aluminum pipe is placed in the end holes of hollow stabilizing rod
Place, is made aluminum pipe be contacted with the end holes of hollow stabilizing rod, hollow stabilizing rod is heated using intermediate-frequency heating furnace, is heated to
700-800 DEG C, then utilize end forging machine forging molding.
The production process of hollow stabilizing rod：Blanking first, steel seal is printed on the raw material of selection, then workpiece is held
Workpiece, is sent in conducting furnace heats afterwards by head forging（Heating-up temperature is 960 DEG C）, the workpiece after heating is curved on curved machine
Song shaping, is then quenched in quenching tank, is tempered into tempering furnace, correction, using compressed air shotblasting machine shot-peening, is detected a flaw with defectoscope, is used
Injection machine is molded by injection ring, to spraying coating line on spray.
