Abstract
The utility model relates a sintering accessory, which is characterized in that the interior of the accessory is hollow, one side the accessory is provided with an opening, a platform is arranged at the opening, a supporting block is arranged on the platform, and the supporting block is provided with a through groove. The sintering accessory has the advantages that the weaknesses of the long-straight operational knife handle which is deformed after being sintered can be effectively improved, the required planeness of the product can be ensured, the processing is simple, and the sintering accessory is applicable to the long straight product of mass production of the discontinuous sintering furnace.
Description
Technical field
The utility model relates to a kind of sintering accessory, relates in particular to a kind of powder injection forming sintering accessory that is used for long straight workpiece.
Background technology
Metal powder injection molded (MIM) is a new forming technique that develops rapidly in the world in recent years, it is advantageous that the small-sized parts that can form any complicated shape, and each position density of goods is even, excellent performance.General technological process is for to be uniformly mixed into fine metal dust and organic binder for having the material of rheological characteristic, the die cavity that adopts advanced injector injection to have part shape forms blank, new technology removes adhesive and through sintering, make its high compaction become metallic article, one of this critical process wherein is exactly with sintering after the injection unsticking of injection moulding.Sintering process is that first low temperature removes binding agent, forms the sintering neck during high temperature and also grow up gradually between metallic particles, shrinks the fine and close state that is bordering on zero hole that reaches at last.The shrinkage factor of whole process reaches 15%～20%, this has just caused build bigger, length is longer, when conducting oneself with dignity workpiece sintering heavier owing to reasons such as gravity, resistance cause sintering warpage, the easier generation of particularly long and straight workpiece, the length overall of powder injection-molded stainless steel knife handle can reach more than the 15cm, and commonsense method is put defectives such as sintering very easily occurs bending and deformation.
The utility model content
The technical problems to be solved in the utility model is: a kind of sintering accessory that overcomes the sintering warpage problem of long straight knife handle is provided.
In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical problem adopts and is: a kind of sintering accessory, this accessory inner hollow, one side has opening, opening part is provided with a platform, places a back-up block on the platform, and back-up block has through-hole groove.
According to another embodiment of the present utility model, the sintering accessory comprises that further described accessory is that graphite material is made.
According to another embodiment of the present utility model, the sintering accessory comprises that further described back-up block made by ceramic material.
The beneficial effects of the utility model are that employing the utility model can effectively improve long straight knife handle sintering warpage defective, has guaranteed the glacing flatness that product is required, the similar long straight product of simple, the suitable batch (-type) sintering furnace mass production of sintering accessory processing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the structural representation of back-up block in the utility model.
Wherein: 1, accessory, 2, opening, 3, platform, 4, back-up block, 5, through-hole groove.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1-2, a kind of sintering accessory 1, this accessory 1 inner hollow, a side has opening 2, and opening 2 places are provided with a platform 3, place a back-up block 4 on the platform 3, and back-up block 4 has through-hole groove 5.Accessory 1 preferred graphite material is made in the utility model, and back-up block 4 preferably ceramic materials are made.
During use, the injection base of knife handle is stretched into groove 5, and then be bearing on the ceramic support piece 4, thereby keep injection base integral hanging in accessory 1 by the additional hanging block in injection base both sides.So, whole injection base is vertical placement, the opening 2 of accessory 1 up, during sintering, gravity direction is consistent with product lowering direction, has effectively avoided the distortion that is caused by the deadweight of injection base, it is unsettled to inject base itself simultaneously, there is not contact-making surface, the sintering warpage of also having avoided deflation resistance to cause, thus guaranteed glacing flatness behind the product sintering.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
