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 sunshading board rotating shaft.
Background technology
The sunshading board rotating shaft is one of vitals in the sunshading board the inside, and it is related to the function and the operational stability of whole sunshading board.In the prior art, the rotating shaft of processing sunshading board generally comprises following steps: corase grind, punching press plane, polishing plane, correct grinding, bend pipe.The sunshading board rotating shaft that this traditional handicraft is made though also can rotate sunshading board preferably, can make its shaft bending because subpunch flattens face; And two limits, plane protrusion; Need carry out the secondary reconditioning to the place, plane, cause difficulty not only for the processing of centerless grinder, and can not guarantee the R angle of circular arc; Cause the anglec of rotation unstable, abnormal sound takes place when rotating shaft is cooperated with jump ring; Simultaneously, because the secondary reconditioning makes the pipe thickness attenuation of rotating shaft, rotating shaft is weakened in the intensity of the R of circular arc angle, shorten service life, so the processing method of this sunshading board rotating shaft also needs further to improve.
Summary of the invention
Technical problem to be solved by this invention is to provide to above-mentioned prior art present situation that a kind of long service life, rotate effect are good, the processing method of the simple sunshading board rotating shaft of operating procedure.
It is the processing method of this kind sunshading board rotating shaft that the present invention solves the problems of the technologies described above the technical scheme that is adopted, and it is characterized in that including following steps:
One, corase grind roughly grinds rotating shaft to specification;
Two, correct grinding finish grindes the rotating shaft after the corase grind to permissible accuracy;
Three, bend pipe is with the angle of the shaft bending behind the correct grinding to regulation;
Four, punching press stamps out one section plane that can make itself and jump ring cooperatively interact and rotate with the rotating shaft side after the bending, and axial punch goes out the groove of bar shaped at the middle part on plane in the punching press plane.
Five, electroplate, rotating shaft electroplating surface last layer stainless steel layer.
As improvement, corase grind carries out on centerless grinder in the said step 1.
Improve, correct grinding carries out on centerless grinder in the said step 2 again.
Improve again, in the said step 3 bend pipe in the mould of bending by hand bending form.
Improve, in the said step 4 during punching press, being provided with in the rotating shaft both sides and making plane and rotating shaft formation arc radius is the mould of R1 and R2 again.
Compared with prior art; The invention has the advantages that: first bend pipe, punching press plane and groove again: first bend pipe; Can come the angle of control plane with the bend pipe angle, guarantee the accuracy of Plane Angle, thereby reach the convenience of the stable and bend pipe processing of the anglec of rotation; Punching press plane and groove can not cause shaft bending and both sides, plane arc chord angle protrusion, i.e. during punching press then; The rotating shaft body is partly changed into from central slot by outwards expanding, thereby need not carry out the 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 both sides, plane circular arcs is unaffected, makes the anglec of rotation more stable, abnormal sound can not take place when rotating shaft cooperates with jump ring; Simultaneously, the arc tube wall thickness of both sides, plane R angle is constant, and the intensity of both sides, plane circular arc R angle is not suffered a loss, and has prolonged the service life of rotating shaft effectively.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
The processing method of this sunshading board rotating shaft includes following steps:
One, roughly grinds, rotating shaft is placed roughly grind on the centerless grinder to specification;
Two, finish grind, the rotating shaft after the corase grind is continued to place finish grind on the centerless grinder to precision prescribed;
Three, bend pipe, the rotating shaft after will finish grinding again are placed on the angle that is bent to regulation in the crooked mould by hand;
Four, punching press; Rotating shaft side after the bending is stamped out one section plane 2 that can make itself and jump ring cooperatively interact and rotate; And 2 middle part axial punch goes out the groove 4 of one section bar shaped on the plane; When punching press plane 2, both sides, 2 front and back are provided with mould on the plane, and both sides formed arc radius R1 and the R2 that sets before and after this mould can make rotating shaft.
Five, electroplate, rotating shaft electroplating surface last layer stainless steel layer.
Below sunshading board rotating shaft that this processing method is made be described further:
