Abstract
The invention relates to a hinge sleeve and a manufacturing method thereof. The method comprises the following steps: the manufacturing raw materials for the metal materials which are not handled are used for extrusion so as to form a main body that has a base, a supporting part and a containing groove through a first-time rolling processing; then a molding column is held into the containing groove of the main body and the main body which holds the molding column undertakes a second-time rolling processing so as to lead the inner edge of the supporting part to lean on the molding column to take a circular arc shape; later the main body which has the circular arc-shaped supporting part and holds the molding column undertakes heat treatment so as to strengthen the hardness of the main body, and is cut into appropriate length, and finally the molding column is removed so as to form the finished products of the hinge sleeve, thereby not only producing the hinge sleeve with required and stable friction coefficient, but also simplifying the hinge sleeve structure and effectively reducing the occurrence for the probability of unqualified products due to insufficiency or excess of the friction coefficient which is caused by the molding of the hinge sleeve owing to the application of force when in the manufacturing process.
Description
Technical field
The present invention relates to a kind of hinge shaft sleeve and manufacture method thereof, hinge shaft sleeve with containing groove and manufacture method thereof that especially a kind of raw material that utilizes metal material manufactures.
Background technique
Mobile computer, PDA Personal Digital Assistant (Personal Digital Assistant; PDA), 3C electronic equipments such as digital camera and mobile phone, mainly be to adopt hinge (Hinge) to be coupling the mode winding display device and main frame body, in use, as long as can use after will display device launching; If when not using, display device and the doubling of main frame body can be folded, to reduce volume, be convenient to collect and carry.
And the design of hinge mainly is: having provides torsion and makes the function that not only interconnects and can launch relatively between display device and the main frame body, and display device is relative with the main frame body when being deployed into special position, can not be subjected to external force easily and arbitrarily changes both relative positions.
In addition, prior art has disclosed a kind of pivot device of opening and closing movement of may command two objects as described in " pivot device " of TaiWan, China patent announcement M249418 number, and comprising: a surface has the pivot of bevel; And a plurality of pads with open axis hole, wear for pivot, and axis hole has the tangent plane of a corresponding pivot bevel, the frictional force that is produced when rotating in axis hole by pivot is to provide the torsion of two object foldings, and when the bevel of pivot just corresponds to the tangent plane of pad, torsion can be disengaged and has the effect of location.
Yet, the assembly of above-mentioned pivot device is more, include a plurality of pads and just can produce required torsion, and its location is the cooperating of tangent plane of bevel and pad by pivot, not only Ding Wei effect is limited, and because pivot is in the inner constantly rotation of the axis hole of pad, so bevel and tangent plane is all very easy is worn, even tightness degree between pivot and the pad is descended and influences the ability that it provides torsion.
In addition, prior art is as described in " multifunctional paper feeding machine and cover plate thereof and the Hinge connecting structure thereof " of TaiWan, China patent announcement M251049 number, its Hinge connecting structure is to utilize a junction to be located at an end of an elastic structure, and the other end of this elastic structure is located in a pin-joint part, and with rotating mode and cover plate main body pivot joint, has a gap between this pin-joint part and this joint, when this cover plate main body rotation is raised, it applies a thrust to this pin-joint part, and make this elastic structure utilize its elastic force, change the clearance distance between pin-joint part and this joint, make this cover plate main body can utilize this Hinge connecting structure to reach the purpose of folding.
But, two fixed positions that above-mentioned Hinge connecting structure can only provide this cover plate main body to open and cover, can not be required according to the user, be adjusted to any appropriate location, and this elastic structure is under long-term the use, easily produce the phenomenon of elastic fatique, or under improper behaviour in service, exceed the elastic range that this elastic structure can bear and cause this elastic structure fracture; Above variety of problems, real is at present relevant industry problem anxious to be solved.
Summary of the invention
For addressing the above problem, main purpose of the present invention is to provide a kind of hinge shaft sleeve and manufacture method thereof.
According to above-mentioned purpose, the present invention proposes a kind of hinge shaft sleeve manufacture method, comprises following steps:
One undressed metallic material is provided;
This metallic material is carried out rolling finishing one time through a roller, and formation has a main body of a base, a supporting portion and a containing groove;
One shaping column is placed in this containing groove of this main body;
This main body that is equipped with this shaping column is carried out secondary rolled processing through another roller, make this supporting portion inner edge be circular-arc against this shaping column;
After this main body that will have circular-arc supporting portion and ccontaining this shaping column is heat-treated in the lump, cut into suitable length;
Again this shaping column is taken out, form the finished product of a hinge shaft sleeve.
Another object of the present invention is to: provide a kind of hinge shaft sleeve when rotating, to produce frictional force and the structure of required torsion when providing drive end to launch with respect to Partner.
According to above-mentioned purpose, structure of the present invention comprises a main body, and this main body is provided with a supporting portion with opening and reaches a base adjacent with this supporting portion, and this inside, supporting portion roughly is circular-arc and is provided with a containing groove.
According to hinge shaft sleeve manufacture method of the present invention, be to utilize the preferable and lower-cost metallic material of ductility to carry out the production method of special processing, not only can produce hinge shaft sleeve with required and stable friction factor, more simplified the structure of this hinge shaft sleeve, effectively reduce in manufacture process because of the application of force makes hinge shaft sleeve and be shaped, and cause friction factor not enough or too cause the probability of defective products to take place.
