Abstract
The invention discloses a kind of metal powder injection molding assembling parts application, the principle that will be reduced by product after being sintered after metal powder injection molding, together by two part combinations, it is set not need the subsequent auxiliary processes such as welding, and can guarantee the stability of workpiece connection, comprising steps of a. prepares manufactured rotating part；B. the connector blank of metal powder injection molding is made；C. it combines connector with rotating part, and fixes the position of connector and rotating part；D. the connector after fixed Combination is sintered, sintered connector, which reduces and then carries out ring set to rotating part, to be locked.
Description
Technical field
The present invention relates to metal powder injection molding fields, more specifically more particularly to a kind of metal powder injection at
Application of the type in assembling parts.
Background technique
During part assembles, carried out during product group matches for the part material of non-resilient material, mutual connection side
Formula is attached after selecting fractionation part mostly using screw or other modes, and is attached using screw or other methods
Reliability it is mostly not high, and step is complicated.
Summary of the invention
The object of the present invention is to provide a kind of metal powder injection moldings in the application of assembling parts, passes through metal powder
Different shrinkage after the injection moulding sintering of end meets part and assembles clearance fit, crosses win cooperation, the effect that welding is confined, and even
Connect reliability height.
To achieve the above object, the invention provides the following technical scheme: a kind of metal powder injection molding is in assembling parts
Application, comprising the following steps:
A. prepare manufactured rotating part；
B. connector blank is made using the method for metal powder injection molding；
C. connector and rotating part are combined, and fix the position of connector and rotating part；
D. the connector after fixed Combination is sintered, sintered connector reduces and then carries out ring to rotating part
Set is locked.
Further: the fusing point of the rotating part is greater than the connector sintering temperature of metal powder injection molding.
Further: part orifice diameter is greater than rotating part connector diameter, connector before the connector is sintered
The part orifice diameter that rear connectors are completed in sintering is less than rotating part connector diameter.
Compared with prior art, the beneficial effects of the present invention are:
The present invention makes the part after metal powder injection molding reduce the group for reaching different parts by sintering process
Match, and may be implemented mold cannot molding component, by combination be made into one-piece parts, the latter linked reliability of part combination
It is high.
Detailed description of the invention
Fig. 1 is three-dimensional explosion views of the invention；
Fig. 2 is main view explosion views of the invention.
Specific embodiment
The present invention is elaborated in conjunction with attached drawing below, so that advantages and features of the invention can be easier to by ability
Field technique personnel understand, apparent explicitly define to make to protection scope of the present invention.
According to Fig. 1-2, the present invention provides a kind of technical solutions: a kind of metal powder injection molding is in part group
The application of dress, comprising the following steps:
A. prepare manufactured rotating part；
B. connector blank is made using the method for metal powder injection molding；
C. connector and rotating part are combined, and fix the position of connector and rotating part；
D. the connector after fixed Combination is sintered, sintered connector reduces and then carries out ring to rotating part
Set is locked.
Embodiment one:
In production, by advance getting out rotating part to be connected, the fusing point of this rotating part is greater than for we
Then the sintering temperature of connector to be sintered is calculated the connector size of metal powder injection molding by deploying,
That is: part orifice diameter is larger than rotating part connection multiplied by shrinkage size after the connector sintering of metal powder injection molding
Head diameter, make part connector that connector hole in piece part can be inserted, by after assembling rotating part and connector fix, to even
Fitting is sintered process, and after the completion of sintering process, the part orifice diameter of connector is less than the connector diameter of rotating part,
It is fixedly mounted on the connector of rotating part in the hole in piece part of connector.
Embodiment two:
In production, we mix the part blank of the metal powder injection molding of two kinds of different shrinkages according to drawing,
Respectively rotating part and connector the hole in piece part ring set of connector are fixed on the connector of rotating part, then
Process is sintered to fixed rotating part and connector, because the sintering shrinkage of rotating part and connector is different, make its
The connector for reaching rotating part after the completion of sintering is fixedly mounted in the hole in piece part of connector.
It should be understood that the rotating part, connector and attached drawing in the present invention are used for the purpose of making technical staff convenient
Understand the contents of the present invention, it is not limited to application of the invention.
The foregoing is merely better embodiment of the invention, protection scope of the present invention is not with above embodiment
Limit, as long as those of ordinary skill in the art's equivalent modification or variation made by disclosure according to the present invention, should all be included in power
In the protection scope recorded in sharp claim.
