Abstract
A rotating shaft of a sun-shading board includes a rotating shaft body (1), wherein the rotating shaft body (1) includes a head part (11) and a main body (12) that are connected in a zigzag form, and an inward concave plane (2) capable of enabling the rotating shaft body (1) and a clamp spring to rotate in a mutual fit manner is arranged on the main body (12). The rotating shaft of the sun-shading board is characterized in that a strip-shaped groove (4) is arranged in the axial direction on the plane (2), and has the advantages that the strip-shaped groove is arranged in the axial direction on the plane; the groove prevents the plane from presenting the phenomenon that arc chord angles are protruded on both sides during the stamping, so that secondary grinding is avoided; as a result, not only are the machining links reduced, but also the operation is convenient and easy, and further, the angle degree of the plane is prevented from being influenced, the rotating angle is enabled to be more stable, and the match of the rotating shaft and the clamp spring makes no abnormal sound; and at the same time, the width of the pipe wall of the rotating shaft at the plane remains unchanged, and the service life of the rotating shaft is efficiently prolonged.
Description
Technical field
The utility model relates to a kind of automotive sunshade panel manufacture technology field, especially refers to a kind of automotive sunshade panel rotating shaft.
Background technique
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 existing technology, 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 tratitional technology 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 grinding machine, and can not guarantee the R angle of circular arc; Cause angle of swing 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 working life, so the structure of this sunshading board rotating shaft also needs further to improve.
Summary of the invention
The utility model technical problem to be solved is that a kind of long service life, sunshading board rotating shaft that rotate effect is good are provided to above-mentioned existing technology present situation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the rotating shaft of this sunshading board; Include the rotating shaft body; Said rotating shaft body is formed by connecting head and main body; Be bending-like between said head and the main body, said main body is provided with the plane that can make rotating shaft body and jump ring cooperatively interact and rotate, and it is characterized in that: the groove that on said plane, axially is provided with bar shaped.
As improvement, said groove is the plane, front and back with plane separation, and said frontal plane and main body side form circular arc, and its radius is R1, and said back plane and main body side also form circular arc, and its radius is R2.
Improve, said groove is arranged on the middle part on plane, and R1=R2 again.
Improve, said groove is arranged on the eccentric position on plane, and R1>R2 or R2>R1 again.
Improve, said plane is arranged on the middle part of main body again.
Improve, the concrete structure that is bending-like between said head and the main body is: said head is vertical each other with main body, and joint is curved again.
Improve the overall structure that said head and main body form for the integral tube single use deflectable again.
Improve, said rotating shaft body is the hollow tubular that surface electrical is coated with one deck stainless steel lining again.
Compared with prior art, the advantage of the utility model is: axially be provided with the groove of bar shaped on the plane, phenomenon is outwards protruded on the both sides that this groove makes the plane when punching press, eliminate the rotating shaft body; When being punching press; The rotating shaft body is partly changed into from central slot by original outwards expanding, so need not carry out the secondary reconditioning, 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 angle of swing 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 working life of rotating shaft effectively.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1 to 5, the rotating shaft of this sunshading board includes rotating shaft body 1, and rotating shaft body 1 is coated with the hollow tubular of one deck stainless steel lining for surface electrical.Rotating shaft body 1 includes head 11 and main body 12; Head 11 and 12 mutual vertical and curved connections of main body; Main body 12 is provided with the plane 2 that can make rotating shaft body 1 and jump ring cooperatively interact and rotate, and plane 2 is arranged on the middle part of main body 12, on plane 2, axially is provided with the groove 4 of bar shaped. Plane 21,22 before and after groove 4 is divided into plane 2, frontal plane 21 forms circular arc with main body 12 sides, and its radius is R1, and back plane 22 forms circular arc with main body 12 sides, and its radius is R2.Groove 4 can be arranged on the middle part on plane 2, and R1=R2, and groove 4 also can be arranged on the eccentric position on plane 2, and R1>R2 or R2>R1.The overall structure that head 11 and main body 12 form for the integral tube single use deflectable.Also be provided with one section Baltimore groove that caves inward 3 in the end of main body 12.
Below this rotating shaft processing method is described further:
The processing method of this sunshading board rotating shaft includes following steps:
One, roughly grinds, rotating shaft is placed roughly grind on the centerless grinding machine to specification;
Two, finish grind, the rotating shaft after the corase grind is continued to place finish grind on the centerless grinding machine to permissible accuracy;
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 stamps out one section plane 2 with the rotating shaft side after the bending, and 2 middle part axial punch goes out the groove 4 of one section bar shaped on the plane, and this punching press is carried out in that plane 2 is formed in the mould that radius of arc is R1 and R2 with rotating shaft body 1;
