Embodiment 1

[0017] Such as figure 1 and figure 2 A hook-type spring protection device for a bell-type sintering box is shown, including a base 1, a sintering box 2 and a graphite disc 3 inside the sintering box 2, wherein the bottom of the sintering box 2 has a backing plate with an inverted U-shaped cross section 4. There is a water tank 11 at the opposite position of the base 1, and the backing plate 4 is placed in the water tank 11, and there is a hook spring 5 between them.

[0018] In order to prevent the hook type spring 5 from turning over when being subjected to force, the hook type spring 5 is designed to be composed of a spring base 10, a spring 12, a support plate 8 and a hook frame 9.

[0019] In order to ensure that the springs are balanced when they are under the pressure of the sintering box 2, there are three hook-type springs 5, which are evenly distributed in the water tank 11.

Embodiment 2

[0021] In order to enhance the effect of the hook type spring and play a double protection role, the water tank 11 shown has sealing water 6, and other structures are the same as the first embodiment.

Embodiment 3

[0023] There are four hook-type springs 5, which are evenly distributed in the water tank 11, and other structures are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a hook-type spring protection device for a bell-type sintering box, which belongs to bell-type sintering box equipment, and includes a base (1), a sintering box (2) and a graphite disk in the sintering box (2) (3), mainly through the hook spring (5) and sealing water (6) to store and release energy to protect the sintering box (2), avoiding the expansion and cracking of the sintering box, or being affected by its own gravity when shrinking Effect, elongation of the sintering box and cracking of welding points.

Description

technical field [0001] The invention relates to a bell-type sintering box equipment, in particular to a hook-type spring protection device for a bell-type sintering box. 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, and 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, and the sintered graphite disks that transmit the pressure are placed on the sintered parts. , then cover the sintering box (protective cover), and then cover the heating bell jar. The two covers sink into the sealed water pool under the action of their own weight, pass the protective gas (explosive), and energize for heating and sintering. Usually the sintering temperature is at 800-1040°C, after 2-3 hours of high-temperature sintering, the heating bell jar is ...
