Description
Technical Field
The utility model relates to a powder metallurgy injection moulding field, in particular to novel notebook pivot.
Background
With the development and progress of society, people have higher and higher requirements for materials, especially consumer electronics products are gradually turning to aspects of lightness, thinness, portability and the like, so that parts of parts are continuously adjusted in structure to meet new changes. Compared with the prior art, the product has a complex structure, the product assembly structure and the product volume are greatly different from those of the prior art, and the structure is gradually developed into a normal state under the current development situation.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art's defect, provide a neotype notebook pivot, adopt the metal alloy material to replace, improve product hardness and toughness through carburization thermal treatment, make its realization carry out mass production.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a novel notebook pivot, including pivot body and connecting axle, the pivot body is "P" font structure, the one end of pivot body is provided with the connecting axle, just the connecting axle is hollow structure, the connecting axle excircle is provided with the oil groove, just the intermediate position of connecting axle extends a little boss on the surface and is used for the location be provided with two circular through-holes on the pivot body platform, the cavity position of connecting axle is the threading groove.
As a novel notebook pivot preferred technical scheme of the utility model, the whole that pivot body and connecting axle are constituteed is hollow structure and the department of buckling is the circular arc transition.
As the utility model discloses a novel notebook pivot preferred technical scheme, pivot body and connecting axle adopt the powder metallurgy shaping.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses the part internal organization is even, and density can reach 98-99.5%, and intensity, hardness, toughness, wear resistance can both satisfy the requirement, and size precision is high, and the surface finish is good, and the mould once takes shape, and key dimension is guaranteed in the machining, satisfies the customer's requirement.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:
FIG. 1 is a block diagram of the present invention;
in the figure: 1. a rotating shaft body; 2. a connecting shaft; 3. an oil sump; 4. a small boss; 5. a circular through hole; 6. a threading groove.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention. Wherein like reference numerals refer to like parts throughout.
In addition, if a detailed description of the known art is not necessary to show the features of the present invention, it is omitted. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Example 1
As shown in fig. 1, the utility model relates to a novel notebook pivot, including pivot body 1 and connecting axle 2, pivot body 1 is P font structure, and pivot body 1's one end is provided with connecting axle 2, and is provided with oil groove 3 on the connecting axle 2, and the intermediate position of connecting axle 2 extends a boss 4 for the location is provided with two locks on pivot body 1 is close to the platform of recess and attaches countersunk hole 5, and the assembly line all passes from hollow wire casing 6.
The bending part of the rotating shaft body 1 is in arc transition.
The rotating shaft body 1 and the connecting shaft 2 are formed by powder metallurgy injection molding, and raw materials comprise a binder and metal powder.
The utility model discloses with binder and metal powder, arrange the blendor in and evenly mix, prepare out required feed
The utility model discloses the product structure is complicated, and the mould structure that relates is also fairly complicated, and the slider is more and increased the side mechanism of loosing core. Compared with plastic, the metal feeding is poor in flowability and toughness, so that the forming and demolding are difficult, the product can be scratched, the scratch and the like, in order to ensure smooth demolding after injection molding, the demolding structure starts to be integrally ejected by a sliding block, then the ejection is carried out by an ejector pin, an ejection mechanism returns, and mold assembly is carried out for the next injection. Through the improved die structure, the product can be smoothly ejected out of the die without damaging the product.
Firstly, will the utility model discloses a blank is put neatly and is carried out the catalytic degreasing, after a period, takes off the partial paraffin among the binder, arranges the degrease piece in vacuum sintering stove again and heats to 800 and give precalcining to adding well 900 ℃, carries out high temperature sintering and obtains required goods, and the easy tail end warp of sintered product warp and warp, through back processing procedure plastic frock adjustment at last, corrects it to required size, carries out thermal treatment and electroplates, obtains required goods.
The utility model has the advantages of uniform internal organization of the parts, high strength, hardness and wear resistance which can reach 98-99.5%, high size precision, good surface smoothness, one-step forming, no need of post-processing and greatly reduced cost.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
