Description
Technical Field
The utility model relates to a sintering technical field specifically is a MIM metalwork sintering tool.
Background
Sintering, which means to convert the powdery material into a compact, is a traditional process. This process has long been used to produce ceramics, powder metallurgy, refractory materials, ultra high temperature materials, and the like. Generally, after the powder is shaped, the dense body obtained by sintering is a polycrystalline material whose microstructure is composed of crystals, vitreous bodies and pores. The sintering process directly affects the grain size, pore size and grain boundary shape and distribution in the microstructure, thereby affecting the performance of the material.
When the metal piece is sintered, a jig is needed for improving the sintering safety and improving the forming rate of the metal piece, but many metal pieces have multiple structures or are polygonal at present, and the common planar sintering jig is difficult to meet the requirements and can cause the conditions of edge collapse, deformation and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a MIM metalwork sintering tool mainly comprises sintering tool body, first step face, second step face, third step face, and this sintering tool designs for the appearance of laminating metal spare, makes sintering tool and metalwork perfect laminating together, forms a whole, has effectually prevented to a certain extent that the metalwork from collapsing the limit, warping.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a MIM metalwork sintering tool, includes the sintering tool body, the external profile of sintering tool body sets up to one side phase-match with the metalwork, the top of sintering tool body is first step face, one side of first step face is equipped with the second step face, one side of second step face is equipped with the third step face.
Preferably, the sintering jig body is arranged in a step mode, and the cross section of the sintering jig body is arranged in a rectangular mode.
Preferably, one side of the metal piece is provided with three faces which are a first side face, a second side face and a third side face respectively, and included angles between every two three faces are 90 degrees.
Preferably, the first step surface is attached to the first side surface of the metal piece, and the horizontal length of the first step surface is greater than that of the first side surface.
Preferably, the second step surface is attached to the second side surface of the metal piece, and the horizontal length of the second step surface is consistent with that of the second side surface.
Preferably, the third step surface is attached to a third side surface of the metal piece, and the horizontal length of the third step surface is greater than that of the third side surface.
Compared with the prior art, the beneficial effects of the utility model are that:
the metalwork is when sintering, and wherein one side can laminate with the sintering tool body, forms a whole, and the opposite side of metalwork can guarantee that complete messenger sintering material fills in the mould when moulding like this, can make the metalwork at complete moulding like this, can not be uneven because of the atress to lead to the inside sintering material of mould to fill inhomogeneously, greatly reduced can appear when the metalwork shaping collapse the limit, the circumstances such as deformation, alleviateed back workshop section pressure, improved production efficiency.
