Problems solved by technology

Among the powder metallurgy products, there is a kind of elongated powder metallurgy products with large ratio of length, width and height, such as cemented carbide cutting and grooving blades. During the sintering process, key parts should be prevented from being damaged by contact with the boat. Long strip products cannot be placed flat or upright. The usual practice is to carefully place them on their sides in a flat boat. The adjacent products of adjacent products are dumped continuously (domino effect), causing the products to collide with each other and be damaged

Embodiment Construction

[0022] figure 1 with figure 2 It shows an embodiment of a multipurpose boat for powder metallurgy sintering of the present invention, the boat includes a disc-shaped graphite boat body surrounded by side walls 2 and bottom plate 1, and the graphite boat body is circular The graphite boat body is provided with several grooves 11 on the outside of the bottom plate 1. When the graphite boat body is turned upside down, these grooves 11 can be used to place the elongated powder metallurgy sintered body 3 that must be placed sideways. The groove 11 can be used to prevent the elongated powder metallurgy sintered body 3 placed sideways from toppling during the process of transfer and furnace loading, so as to avoid the products being damaged due to mutual collision. Therefore, the boat of the present invention can be used when the graphite boat body is normally placed It is used to sinter conventional powder metallurgy sintered bodies with general shapes, and can also be used to sin...

Abstract

The invention discloses a multipurpose boat for powder metallurgical sintering, which comprises a disk-shaped graphite boat body surrounded by a side wall and a base plate, wherein a plurality of grooves for accommodating the strip-shaped powder metallurgical sintering body are formed outside the base plate of the graphite boat body. The multipurpose boat for powder metallurgical sintering has the advantages of simple structure and wide application range, and is capable of reducing the handling cost of material. The invention further discloses a multipurpose boat unit which is made by overlapping more than two boats.

Description

technical field [0001] The invention relates to a tool for powder metallurgy sintering process, in particular to a multipurpose boat used for powder metallurgy sintering. Background technique [0002] Sintering is a crucial process in powder metallurgy production, which will endow powder metallurgy products with certain shape, size, microstructure and physical and mechanical properties. Among the powder metallurgy products, there is a kind of elongated powder metallurgy products with large ratio of length, width and height, such as cemented carbide cutting and grooving blades. During the sintering process, key parts should be prevented from being damaged by contact with the boat. Long strip products cannot be placed flat or upright. The usual practice is to carefully place them on their sides in a flat boat. The adjacent products of the adjacent products are continuously dumped (domino effect), causing the products to collide with each other and be damaged. Contents of th...
