In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.
[0033] As Figs. 1-3As shown, in the embodiment, the hot isostatic pressing sleeve includes a sleeve body and two sealing plates 4. The sleeve body includes a top plate 1, a bottom plate 2, and two side plates 3. The bottom plate 2 is arranged in a spaced-apart manner with the top plate 1. The side plates 3 are in a concave structure. The two side plates 3 are arranged in a spaced-apart manner and surround the top plate 1 and the bottom plate 2 to form a rectangular closed structure. The two sealing plates 4 are arranged at the two end openings of the sleeve body. Specifically, the top plate 1, the bottom plate 2, and the two sealing plates 4 are all planar plates. The two side plates 3 are bent into a concave structure through a bending process. The two side plates 3 are respectively arranged on the two sides between the top plate 1 and the bottom plate 2 and surround the top plate 1 and the bottom plate 2 in sequence to form the sleeve body in a rectangular closed structure. The sleeve body has openings at the two ends. The two sealing plates 4 are fixedly connected with the two end openings of the sleeve body and seal the openings. The hot isostatic pressing process is to place the product into a closed container, apply isotropic pressure to the product, and apply high temperature at the same time. Under the action of high temperature and high pressure, the product can be sintered and densified. The hot isostatic pressing can directly form a powder. The powder is loaded into the sleeve. The sleeve can be made of metal or ceramic. Then, nitrogen or argon is used as a pressurizing medium to make the powder directly sintered and formed through a powder metallurgy process. During the hot isostatic pressing process, the side plates 3 are in a concave structure to provide deformation amount in the shrinkage process. That is, the two side plates 3 in a concave structure provide a larger deformation amount in the sintering process, so as to prevent the sleeve from being easily broken. At the same time, the stress in each direction is more uniform during the shrinkage process. The extended part of the side plate 3 can play a good supporting role to effectively prevent the sleeve from being bent and reduce the abnormal rate of the sleeve.
[0034] Further, with reference to Figs. 1-3 , the side plate 3 includes an intermediate portion 31 and two side edge portions 32. The two side edge portions 32 are respectively connected to the two sides of the intermediate portion 31, and the two side edge portions 32 are respectively fixedly connected with the top plate 1 and the bottom plate 2. Specifically, the two side plates 3 are arranged in parallel with each other. The two side edge portions 32 are respectively welded to the extended portion of the top plate 1 and the extended portion of the bottom plate 2, that is, the two side edge portions 32 are fixedly connected through welding. After welding, the welding slag needs to be removed through a distributed cleaning technology. The two side end portions of the top plate 1 and the two side end portions of the bottom plate 2 are flush with the end faces of the side edge portions 32, so as to provide a good deformation amount in the shrinkage process and prevent the sleeve from being broken. The sleeve body and the sealing plate 4 are both made of stainless steel material, which has high structural strength and good welding effect.
[0035] Further, with reference to Figs. 1-3The sealing plate 4 is fixedly connected to the sleeve body by welding, and the sealing plate 4 seals the opening of the sleeve body. During the shrinkage process, the force is more evenly distributed in all directions. The extended part of the side plate 3 can provide good support and effectively prevent the sleeve from bending. The sleeve body has an "I" shaped structure, and the end face of the sealing plate 4 is flush with the opening end face of the sleeve body, which makes the sealing plate 4 provide better support for the sleeve body and more evenly distributed in all directions during the shrinkage process. The sealing plate 4 has a through hole 41, which allows the heat inside the sleeve to be dissipated in time during the hot isostatic pressing sintering process, achieving a good heat dissipation effect.
