The invention further discloses a multipurpose boat unit which is made by overlapping more than two boats.
Description
Technical field
The present invention relates to be used for the instrument of powder metallurgical sintering process, relate in particular to and be used for powder metallurgy sintered multipurpose boat.
Background technology
Sintering is one vital operation during powder metallurgy is produced, and it will give the certain shape of sintered metal product, size, microstructure and physical and mechanical properties.In sintered metal product, there are class length and width to differ bigger strip powder metallurgy product at high proportion, for example carbide alloy cuts off section groove blade, to prevent that in sintering process key position from contacting and being damaged with boat, therefore can not keep flat for this strip product, more can not uprightly put, common way is careful with its edge-on being placed in the dull and stereotyped boat, but in the process of transhipment and shove charge, still can topple over (domino effect) owing to vibration causes the edge-on adjacent product of putting to recur, cause product to collide mutually and damage.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and a kind of simple in structure, applied widely, powder metallurgy sintered multipurpose boat that is used for that can reduce the handling of goods and materials cost is provided, and the multipurpose boat group of being made up of this boat.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind ofly be used for powder metallurgy sintered multipurpose boat, comprise the plate-like graphite boat body that is surrounded by sidewall and base plate, described graphite boat body is provided with the some grooves that are used to place the powder metallurgy sintered body of strip in the outside of base plate.
Described some grooves layout that is parallel to each other.
Described some grooves are divided into many group groups of slots, 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.
Evenly be provided with several through holes on the described base plate.
A kind of multipurpose boat group, it is formed by stacking by the powder metallurgy sintered multipurpose boat that is used for above-mentioned more than two.
Compared with prior art, the invention has the advantages that:
Of the present inventionly be used for powder metallurgy sintered multipurpose boat, on the graphite boat body, be provided with some grooves in the outside of base plate, can be used to place must the powder metallurgy sintered body of the edge-on strip of putting for these grooves when the graphite boat body was inverted, this groove can be used for preventing that the powder metallurgy sintered body of the edge-on strip of putting from toppling in the process of transhipment and shove charge, avoid product to collide mutually and damage, therefore boat of the present invention both can be used for the conventional powder metallurgy sintered body of the general shape of sintering when the graphite boat body is normally placed, can when the graphite boat body is inverted, be used for sintering again and have the special powder metallurgy sintered body of strip of putting requirement, applied widely, be convenient to management, can reduce the handling of goods and materials cost.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 wider, and the groove of different in width can be set on same graphite boat body, to be used for the powder metallurgy sintered body of strip of the different sizes of sintering, further improve its adaptive capacity.On base plate, evenly be provided with several through holes, not only can satisfy in sintering process requirement, and make that the atmosphere Density Distribution of boat inside is even, thereby make product composition more even, more stable quality the atmosphere flowability.Multipurpose boat group of the present invention is formed by stacking by being used for powder metallurgy sintered multipurpose boat more than two, the conventional powder metallurgy sintered body that is used for the general shape of sintering when adopting conventional forward to superpose, be used for sintering when adopting the inversion stack and have the special powder metallurgy sintered body of strip of putting requirement, simple in structure, with low cost, applied widely.
