Isostatic pressure forming device for preparing magnet by powder metallurgy method

Abstract

The invention discloses an isostatic pressure forming device for preparing a magnet by a powder metallurgy method. The isostatic pressure forming device comprises a static pressure forming tank body;a fixing base plate is arranged at the bottom of the static pressure forming tank body; the static pressure forming tank body is in sealing connection with the fixing base plate; a fixing end cover isarranged at the top of the static pressure forming tank body; sealing cushion blocks are arranged on the left side and the right side of the interior of the fixing end cover and are bonded with the static pressure forming tank body; fixing cushion blocks are arranged on the left side and the right side of the interior of the static pressure forming tank body; the fixing end cover and the fixing cushion blocks are buckled to achieve sealing; an isostatic pressure forming groove is formed in the static pressure forming tank body; a pressure valve block is arranged on the upper left side of theisostatic pressure forming groove; and the left side of the pressure valve block is connected with a fixing air pipe. The pressure and temperature of equipment are convenient to adjust and control integrally, the quality of a machined workpiece is relatively high, the machining efficiency is improved, the integral structure is simple, and the functionality is relatively high.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy equipment, in particular to an isostatic pressing forming device for preparing magnets by powder metallurgy. Background technique [0002] Isostatic pressing is to place the sample to be pressed in a high-pressure container, and use the incompressible properties of the liquid medium and the properties of uniform pressure transmission to uniformly pressurize the sample from all directions. When the liquid medium is injected into the pressure vessel through the pressure pump , according to the principles of fluid mechanics, its pressure is constant and uniformly transmitted to all directions. At this time, the pressure on the powder in the high-pressure container is uniform and consistent in all directions. The method of forming a dense body from barren powder through the above method is called isostatic pressing. [0003] In powder metallurgy, the principle of isostatic pressing is ofte...

Problems solved by technology

[0003] In powder metallurgy, the principle of isostatic pressing is often used to make workpieces. However, most of the traditional isostatic pressing devices are suitable for liquids and are not suitable for powder metallurgy. There is a lack of isostatic pressing devices for powder metallurgy on the market, and Traditional equipment is relatively poor in terms of pressure regulation and temperature control, and the quality of the produced workpieces is not good. The above problems need to be improved on traditional equipment, so how to design an isostatic press for the preparation of magnets by powder metallurgy Forming device, this becomes the problem we need to solve
