Embodiment Construction

[0010] The technical scheme of the present invention is described in detail below in conjunction with specific embodiment:

[0011] Such as figure 1 A bell-jar sintering box protection device shown includes a base 1, a sintering box 2, and a graphite disc 3 inside the sintering box 2, and the sintering box 2 is welded by a shell head, a shell and a shell bottom welding point 6, There is a backing plate 4 with an inverted U-shaped cross-section at the bottom of the sintering box, and a water tank 7 is arranged at the corresponding position between the base 1 and the backing plate. The backing plate 4 is placed in the water tank 7, and there is sealing water 5 as a buffer between them.

[0012] When working, first apply a certain pressure to the sintering box 2, and keep it constant. When the sintering box 2 is subjected to external force, the force is transmitted to the backing plate 4, and then the sealing water is compressed, and the energy is converted into internal energy s...

Abstract

The invention discloses a bell-jar type sintering tank protecting device, and relates to bell-jar type sintering equipment. The device comprises a base (1), a sintering tank (2) and a graphite disc (3), wherein the graphite disc (3) is arranged in the sintering tank (2), the sintering tank (2) is provided with welding points (6), the edge of the base (1) is provided with a water tank (7), the bottom of the sintering tank (1) is provided with a cushion plate (4), the cross section of the cushion plate (4) is in an inverted U shape, the cushion plate (4) is arranged in the water tank (7), and sealing water (5) is arranged between the cushion plate (4) and the water tank (7) to realize the buffering function. The device has the advantages that by utilizing the compression and expansion of the sealing water (5), the phenomena of the cracking of the welding points (6), the lengthening of the jar body and the like due to the high-temperature expansion or low-temperature shrinkage of the sintering tank (2) are avoided, and the phenomena of the blocking of the resetting of a sintering transverse beam, the oxidization of products, the sintering of waste products and the like, caused by the gas leakage of the sintering tank (2) and the lengthening of the sintering tank body are avoided; the phenomenon of pressure not being applied to parts during sintering is avoided; meanwhile, multiple potential safety hazards are omitted.

Description

technical field [0001] The invention relates to a bell-type sintering box equipment, in particular to a bell-jar sintering box protection device. Background technique [0002] Sintering is one of the most important processes in the production of sintered metal friction materials. During the sintering process, the material is compacted. The commonly used equipment for sintered friction materials is a bell furnace. The sintered friction parts are placed on the base in one or several stacks. Put the pressure-transmitting sintered graphite discs on top of the sintered parts, then cover the sintering box (protective cover), and then cover the heating bell jar. Gas (explosive), energized for heating and sintering, usually the sintering temperature is 800-1040°C, after 2-3 hours of high-temperature sintering, the heating bell jar is removed, and then the cooling cover is put on pressurized water cooling, and the sintering box is sintered during the whole sintering process To prote...
