Abstract
A processing method for a rotating shaft of a sunshading board includes the following steps: 1 rough grinding, roughly grinding the rotating shaft to a required specification; 2 accurate grinding, accurately grinding the roughly-grinded rotating shaft to a required precision; 3 pipe bending, bending the accurately-grinded rotating shaft to a required angle; 4 stamping, stamping the side of the bended rotating shaft to be a section of flat surface capable of being matched with a jump ring to rotate; and 5 electroplating, electroplating a stainless steel layer on the surface of the rotating shaft. The processing method for the rotating shaft of the sunshading board is characterized in that a strip-shaped groove is stamped axially in the middle of the flat surface while the flat surface is stamped in step 4. The processing method for the rotating shaft of the sunshading board has the advantages of bending the pipe first and stamping the flat surface and the groove later, ensuring accuracy of the angle of the flat surface due to bending the pipe first because the angle for bending the pipe can be used for controlling the angle of the flat surface so as to achieve stability of the rotation angle and convenience for bending the pipe, causing no bending of the rotating shaft or protruding of two sides of the flat surface due to stamping the flat surface and the groove later and thereby enabling processing of centerless grinder to be convenient, and ensuring size stability because no secondary processing is required at the position of the flat surface.
Description
Technical field
The present invention relates to a kind of manufacture technology field of automotive sunshade panel, especially refer to a kind of processing method of rotating shaft of sunshading board.
Background technology
Rotating shaft of sunshading board is one of vitals in sunshading board the inside, and it is related to function and the operational stability of whole sunshading board.In prior art, processing rotating shaft of sunshading board generally comprises following steps: corase grind, punching press plane, polishing plane, fine grinding, bend pipe.The rotating shaft of sunshading board that this traditional handicraft is made, although also can rotate preferably sunshading board, but because flattening face, subpunch can make its shaft bending, and protrude on plane two limits, need to carry out secondary reconditioning to plane place, cause difficulty not only to the processing of centerless grinder, and can not guarantee the R angle of circular arc, cause the anglec of rotation unstable, abnormal sound occurs when rotating shaft is coordinated with jump ring; Meanwhile, because secondary reconditioning makes the pipe thickness attenuation of rotating shaft, can make rotating shaft at the remitted its fury of the R of circular arc angle, shorten service life, so the processing method of this rotating shaft of sunshading board also needs further improvement.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned prior art present situation, to provide that a kind of long service life, rotate effect are good, the processing method of the simple rotating shaft of sunshading board of operating procedure.
The present invention solves the problems of the technologies described above the processing method that adopted technical scheme is this kind of rotating shaft of sunshading board, it is characterized in that including following steps:
One, corase grind, roughly grinds rotating shaft to specification;
Two, fine grinding, refines the rotating shaft after corase grind to permissible accuracy;
Three, bend pipe, the angle by the shaft bending after fine grinding to regulation;
Four, punching press, stamps out one section of plane that can make itself and jump ring cooperatively interact and rotate by the rotating shaft side after bending, in punching press plane, in the middle part of plane axial punch, goes out the groove of bar shaped.
Five, electroplate, by rotating shaft electroplating surface last layer stainless steel layer.
As improvement, in described step 1, corase grind carries out on centerless grinder.
Improve, in described step 2, fine grinding carries out on centerless grinder again.
Improve again, in described step 3 bend pipe in crooked mould by hand bending form.
Improve again, in described step 4 during punching press, in rotating shaft both sides, be provided with that to make plane and rotating shaft form arc radius be the mould of R1 and R2.
Compared with prior art, the invention has the advantages that: first bend pipe, punching press plane again and groove: first bend pipe, can by bend pipe angle, carry out the angle of control plane, guarantee the accuracy of Plane Angle, thereby reach the convenience of the stable of the anglec of rotation and bend pipe processing; Then punching press plane and groove, can not cause shaft bending and plane both sides arc chord angle to protrude, while being punching press, rotating shaft body is partly changed into from central slot by outwards expanding, thereby does not need to carry out secondary reconditioning and make centerless grinder processing more convenient, and this has not only reduced processing link, make more convenient operation, easier, and the R angle that has guaranteed plane both sides circular arcs is unaffected, makes the anglec of rotation more stable, when rotating shaft coordinates with jump ring, abnormal sound can not occur; Meanwhile, the arc tube wall thickness of plane both sides R angle is constant, and the intensity of plane both sides circular arc R angle is not suffered a loss, and has effectively extended the service life of rotating shaft.
