Description
Technical field
The present invention relates to the instrument for powder metallurgical sintering process, particularly relate to for powder metallurgy sintered Multipurpose boat.
Background technology
Sintering is one vital operation during powder metallurgy is produced, and it will give sintered metal product certain shape, size, microstructure and physical and mechanical properties.The strip powder metallurgy product that a class length, width and height ratio difference is larger is had in sintered metal product, such as carbide alloy cuts off section groove blade, to prevent key position from contacting with boat in sintering process and damaged, therefore can not keep flat for this strip product, more can not uprightly put, common way careful is edge-only placed in dull and stereotyped boat by it, but transhipment and shove charge process in, or can topple over (domino effect), cause product mutually collide and damage because vibration causes the edge-on adjacent product put to recur.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provide a kind of structure simple, applied widely, can reduce handling of goods and materials cost for powder metallurgy sintered Multipurpose boat, and the Multipurpose boat group be made up of this boat.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
For a powder metallurgy sintered Multipurpose boat, comprise the plate-like graphite boat body surrounded by sidewall and base plate, described graphite boat body is provided with the some grooves for placing strip PM sintered materials in the outside of base plate.
Described some grooves are parallel to each other layout.
Described some grooves are divided into organizes groups of slots more, and the groove in each groups of slots is parallel to each other, the mutual arranged crosswise of each groups of slots.
The width of described groove is 1 ~ 10mm.
The degree of depth of described groove is 1 ~ 5mm.
The spacing of described groove is 4 ~ 20mm.
Described base plate is evenly provided with several through holes.
A kind of Multipurpose boat group, it is by above-mentioned being formed by stacking for powder metallurgy sintered Multipurpose boat of two or more.
Compared with prior art, the invention has the advantages that:
Of the present invention for powder metallurgy sintered Multipurpose boat, graphite boat body is provided with some grooves in the outside of base plate, when being inverted by graphite boat body, these grooves may be used for placing the strip PM sintered materials that must edge-only put, this groove can be used for preventing the edge-on strip PM sintered materials put from toppling in the process of transhipment and shove charge, product is avoided mutually to collide and damage, therefore boat of the present invention both can when graphite boat body is normally placed for sintering the conventional powder metallurgical sintered body of general shape, the special strip PM sintered materials putting requirement can be had for sintering again when graphite boat body is inverted, applied widely, be convenient to management, handling of goods and materials cost can be reduced.Groove can be arranged in parallel, also can be divided into many groups and will organize the mutual arranged crosswise of groups of slots more, the size range of groove is comparatively wide, can arrange the groove of different in width on same graphite boat body, for the strip PM sintered materials of the different size of sintering, improve its adaptive capacity further.Base plate is evenly provided with several through holes, can not only meets the requirement to atmosphere mobility in sintering process, and make the atmosphere Density Distribution of boat inside even, thus make product composition more even, quality is more stable.Multipurpose boat group of the present invention is used for powder metallurgy sintered Multipurpose boat by two or more and is formed by stacking, for sintering the conventional powder metallurgical sintered body of general shape when adopting conventional Downward addition, adopt when being inverted superposition and have the special strip PM sintered materials putting requirement for sintering, structure is simple, with low cost, applied widely.
