Single rectangular parallelepiped structure, is welded by six blocks of sheet materials, a pumping connected with jacket inner chamber is fixed on one of sheet material
Pipe.Such wrapping structure is simple, and cost of manufacture is relatively low, but Shortcomings, in the environment of HTHP, the weldering at seamed edge
Socket part position is easy to be broken, or sheet material deforms, so that article shape changes, or the density of product reaches
Less than requiring, cause product unqualified.
Utility model content
In order to solve deficiency of the prior art, the utility model provides a kind of heat especially suitable for pipe fitting product sintering
Isostatic pressed one tubular sheath, the welded seal mode of end can ensure to keep stable under high temperature and high pressure environment, avoid simultaneously
Product deforms.
To achieve these goals, the concrete scheme that the utility model uses for：
A kind of high temperature insostatic pressing (HIP) one tubular sheath, including jacket wall and the exhaust tube that is fixedly installed on jacket wall, wherein wrapping
Jacket wall encloses out a raw material cavity for being used to accommodate powder, and exhaust tube connects with raw material cavity, and the jacket wall includes the outer of tubulose
The inwall of wall and the tubulose being arranged at outer wall center, the upper and lower ends of inner and outer wall are consolidated by upper blocking ring and lower blocking ring respectively
Fixed connection, inwall, outer wall, upper blocking ring and lower blocking ring enclose out the raw material cavity of tubulose jointly, and exhaust tube break-through is simultaneously arranged on stifled
On ring；The section of the lower blocking ring is in U-typed structure and outward opening, the vertical portion of U-typed respectively with inner and outer wall phase
It is bonded and is welded and fixed, the upper blocking ring is identical with the structure of lower blocking ring.
Columned plug is additionally provided with the middle part of the inwall, side wall and the inwall of plug fit.
The length of the plug is more than the length of the raw material cavity.
The lower blocking ring is also fixedly connected with lower cover, and lower cover is also fixedly connected with inner and outer wall.
The lower cover is welding with lower blocking ring, the connected mode of inner and outer wall.
Beneficial effect：
1st, the utility model is sealed to the both ends of jacket using section in the blocking ring of U-typed, when being both avoided that sealing
Welding process powder is had an impact, be also avoided that high pressure tear weld seam；
2nd, increase plug to be used to be supported jacket, avoid its deformation failure article construction；
3rd, it is simple in construction, easy to use, be advantageous to improve production efficiency.

Embodiment
Embodiment of the present utility model is illustrated below according to accompanying drawing.
As depicted in figs. 1 and 2, a kind of high temperature insostatic pressing (HIP) one tubular sheath, including jacket wall and be fixedly installed on jacket wall
Exhaust tube 1, wherein jacket wall encloses out one and is used to accommodate the raw material cavity of powder 6, and exhaust tube 1 connects with raw material cavity, described
Jacket wall includes the upper and lower ends of the inwall 2 of the outer wall 3 and the tubulose being arranged at the center of outer wall 3 of tubulose, inwall 2 and outer wall 3
It is fixedly connected respectively by upper blocking ring 4 with lower blocking ring 8, inwall 2, outer wall 3, upper blocking ring 4 and lower blocking ring 8 enclose out tubulose jointly
Raw material cavity, the break-through of exhaust tube 1 are simultaneously arranged in blocking ring 4；The section of the lower blocking ring 8 is in U-typed structure and outward opening,
The vertical portion of U-typed fits and is welded and fixed with inwall 2 and outer wall 3 respectively, the structure of the upper blocking ring 4 and lower blocking ring 8
It is identical.
The middle part of the inwall 2 is additionally provided with columned plug 5, and side wall and the inwall 2 of plug 5 fit.Plug 5 is used
Inwall 2 is supported in the space full of the middle part of inwall 2, prevents inwall 2 from being deformed in the environment of HTHP, causes product
Quality Down.Particularly, the length of the plug 5 is more than the length of the raw material cavity, to ensure the effect of support.
The lower blocking ring 8 is also fixedly connected with lower cover 7, and lower cover 7 is also fixedly connected with inwall 2 and outer wall 3, and connected mode is
Welding.
The specific method used is.
Inwall 2, outer wall 3, plug 5, lower blocking ring 8 and lower cover 7 are installed first, upper blocking ring 4 is not installed, afterwards will installation
Good straightened portion is set, and lower cover 7 is located at bottom to keep stable, and the position of blocking ring 4 on powder 6 then is filled into raw material
In chamber, then upper blocking ring 4 is put well, and the joint place between upper blocking ring 4 and inwall 2 and outer wall 3 is welded, then from upper stifled
Exhaust tube 1 on ring 4 is outwards evacuated, you can proceeds by high temperature insostatic pressing (HIP).
The structure of upper blocking ring 4 makes it, and solder joint has certain distance apart from powder 6, and welding can be avoided to produce when in welding
High temperature powder 6 is had an impact, cause this alteration of form of amount of powder 6 in hot isostatic pressing and shadow produced to whole product
Ring.And during follow-up high temperature insostatic pressing (HIP), pressure acts on the vertical portion and horizontal part of the U-typed structure of blocking ring 4 simultaneously
Point, compared with traditional direct mode sealed with sheet material, high pressure tear weld seam can be avoided and damage jacket and product.
