Problems solved by technology

The bottom-loading material boat is detachably connected to the base, so that the porous metal material green body can be loaded above the base first, and then the boat is loaded from above the porous metal material green body, solving the problem of porous metal material. The material green body is loaded from the top of the boat, which is easy to cause broken or broken problems, and reduces the difficulty of loading the metal porous material green body, and improves the sintering efficiency

Embodiment 1

[0034] like figure 1 and figure 2 As shown, the bottom-loading material boat for sintering metal porous materials in this embodiment includes a base 1 and a boat tube 2 detachably connected to the base 1. Both ends of the boat tube 2 are openings, and the base 1 and the boat are open. A charging space is formed on the inner side of the boat barrel 2 , the charging space is used for accommodating the green porous metal material, and the charging space is used for accommodating the green porous metal material.

[0035] The existing sintering boat is generally an integrated structure of the base and the boat barrel, and the metal porous material green body is loaded into the sintering boat by loading it from the top of the boat barrel. There is a height difference between the bottom of the blank and the base of the sintering boat, which is easy to cause damage and fragmentation of the metal porous material green body after loading, especially the loading process of heavy or low...

Embodiment 2

[0045] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the base 1 is provided with an annular groove 1-2, and the bottom of the boat tube 2 is clamped in the annular groove 1-2 .

[0046] In this embodiment, the annular groove 1-2 is opened at the position close to the outside of the base 1, and the bottom of the boat tube 2 is clamped in the annular groove 1-2, so that the annular groove 1-2 is opposite to the boat tube. The bottom of 2 plays a limiting role to improve the stability of the boat 2 on the base 1, and further prevent the boat 2 and the base 1 from moving relative to each other, that is, to prevent the packing in the boat 2 from leaking out and prevent the metal porous The material blank moves in the boat barrel 2 to ensure the normal operation of the sintering work.

[0047] The working process of the bottom-loading boat for sintering metal porous materials of the present invention is as follows: place the base 1 on the...

Abstract

The invention discloses a bottom-loading material boat for sintering metal porous materials, which comprises a base and a boat tube detachably connected to the base. The material space is used to accommodate the metal porous material green body. In the present invention, the boat is detachably connected to the base, so that the porous metal material green body can be loaded above the base first, and then the boat is loaded from above the porous metal material green body, which solves the problem of the porous metal material green body Loading above the boat can easily cause the problem of breaking or fragmentation, and reduces the difficulty of loading the metal porous material green body, and improves the sintering efficiency.

Description

technical field [0001] The invention belongs to the field of sintered metal porous materials, in particular to a bottom-loading type boat for sintering metal porous materials. Background technique [0002] Sintered metal porous material is a kind of metal material with special functions that appeared at the beginning of the 20th century and developed rapidly after World War II. Sintered metal porous material is generally a metal porous material prepared by cold forming and high temperature sintering with metal powder as raw material. Because the sintered metal porous material has special pores and pore structure, in addition to the characteristics of the metal material itself, the material also has special functions such as purification and separation, noise reduction and weight reduction, adsorption and slow release, flame retardant and explosion-proof, and efficient heat conduction. At present, sintered metal porous materials have been widely used in filtration and separa...
