Abstract
The utility model discloses a blade sintering tool in metal injection forming technology, including the blade product, the blade product include slim portion of slice and shaft -like thick type portion, still including the support of putting the blade product, the support include base and a plurality of and blade product shape and big or small assorted step hole, step hole upper portion is placed the slim portion of slice and is the supporting part, shaft -like thick type portion is placed to step hole lower part is through -hole portion, the lower surface in close contact with of the slim portion of upper surface and slice of supporting part, the support have a supporting legs, supporting legs bottom to the surperficial height that highly is greater than shaft -like thick type portion of the slim troops under one's command of slice. Through using the mode that the tool satisfies blade product sintering, when overcoming in the MIM technology difficult point, also with the aid of MIM technology, make it obtain more extensive application, no matter be on the cost or in the aspect of the benefit, all to be superior to other processing channel, also contributed strength with improveing for automobile industry's development.
Description
Technical field
This utility model relates to a kind of sintering auxiliary fixture, is specially the blade sintering tool in a kind of metal injection moulding technique, belongs to metal powder injection technical field.
Background technology
Metal injection moulding MIM (MetalinjectionMolding, MIM) is a kind of manufacturing process being injected in model by the plasticising compound of metal dust Yu its binding agent.It is first to be mixed with binding agent by selected powder, the shape required for the injection moulding that then undertaken compound granulating again.The feature of its VISCOUS FLOW is given compound by polymer, and contributes to the uniformity of shaping, mould filling and powder packing.Get rid of binding agent after shaping, then defat base is sintered.Some sintered products are also possible to carry out further densification, heat treatment or machining.Sintered products not only has the complicated shape the same with injection molding of plastics method resulting product and high accuracy, and has the physics close with forging, chemistry and mechanical performance.This Technology be suitable for producing in enormous quantities small-sized, accurate, 3D shape is complicated and has the manufacture of metallic element that property requires.
Along with deepening continuously of MIM research and constantly improving of the exploitation of novel binders, powder-making technique and degreasing process, realize industrialization to the beginning of the nineties.Through the effort of more than 20 years, current MIM become international field of powder metallurgy quickly grow, the novel near-net-shape technology of the most promising one, be described as one of " international the most popular metallic element forming technique ".
In the MIM technique produced, for structure is complicated and also product that profile wall is relatively thin, sintering warpage is always up a difficult point, is directed to this series products, makes special tool when sintering, can have very great help.Slim portion and the thicker portion of not easily sintering warpage that leaf product is generally deformed by easy-sintering form.At present in process of production, it does not have applying special sintering tool, after sintering, slim portion is yielding, revising followed by by the way of artificial shaping.This mode wastes very big manpower, and production efficiency is very low, and unstable, and the yield of finished product is low, affects productivity effect.
The mode of leaf product sintering is met by application fixture, overcome in MIM technique while difficult point, also by way of MIM technique, make it be more widely used, it no matter it is on cost or benefit aspect, will being better than other processing channel, development and improvement for automobile industry have also contributed to strength.
Utility model content
The purpose of this utility model is to provide for the blade sintering tool in a kind of metal injection moulding technique, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions:
Blade sintering tool in a kind of metal injection moulding technique, including leaf product, described leaf product includes the slim portion of lamellar and shaft-like thicker portion；Also including the support putting leaf product, described support includes pedestal and several stepped holes matched with leaf product shape and size, and it is support portion that the slim portion of lamellar is placed on described stepped hole top；It is through-hole section that shaft-like thicker portion is placed in stepped hole bottom；The lower surface in the upper surface of described support portion and the slim portion of lamellar is in close contact；Described support has spike, supports the foot bottom height to the slim lower surface of lamellar more than the height in shaft-like thicker portion.
In general, support portion and slim portion have more large access area, then the sintering warpage of slim portion is more few, but this also means that the slim portion of abnormity needs the support portion of abnormity to support, and this is clearly and adds the difficulty making sintering tool, adds cost.Therefore this utility model adopts the method finding slim portion trunk portion, finds balance between easily making and playing a supporting role.Therefore, closer, the upper surface of described support portion and slim portion have maximum contact surface in the horizontal plane.To ensure that leaf product places balance, uniform force on sintering tool (support).
This utility model method by arranging special support for leaf product, especially carries out large-area setting off to the slim portion of leaf product, so as to be unlikely to deform in sintering process.Shrink according to the pattern of tool, it is possible to solve the problem on deformation that causes of high temperature sintering easily, it is possible to save the operation of artificial shaping, and the good stability of product, efficiency is improved, it is possible to save cost, improves productivity effect.
Accompanying drawing explanation
Fig. 1 is mounting structure schematic diagram of the present utility model；
In figure: 1, the slim portion of lamellar 2, shaft-like thicker portion 3, support 4, support portion 5, through-hole section.
Detailed description of the invention
Of the present utility model construction features is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Blade sintering tool in a kind of metal injection moulding technique as shown in Figure 1, including leaf product, described leaf product includes the slim portion of lamellar 1 and shaft-like thicker portion 2；Also including the support 3 putting leaf product, described support 3 includes pedestal and several stepped holes matched with leaf product shape and size, and it is support portion 4 that the slim portion 1 of lamellar is placed on described stepped hole top；It is through-hole section 5 that shaft-like thicker portion 2 is placed in stepped hole bottom；The lower surface in the upper surface of described support portion 4 and the slim portion 1 of lamellar is in close contact；Described support 3 has spike, supports the foot bottom height to lamellar slim portion 1 lower surface more than the height in shaft-like thicker portion 2.
During use, leaf product to be sintered is placed on the support 3 of coupling, in sintering process, leaf product shrinks according to the pattern of support 3, it is possible to solve the problem on deformation that high temperature sintering causes easily, it is possible to save the operation of artificial shaping, and the good stability of product, efficiency is improved, it is possible to save cost, improves productivity effect.
