Description

Technical Field

[0001] The present invention relates to the technical field of sintering, and more particularly to a sintering device and a method thereof. Background Art

[0002] An insulator is a device that is installed between conductors at different potentials or between conductors and grounded structures and is capable of withstanding voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting hardware.

[0003] Most of the existing processing and sintering devices are horizontal sintering furnaces, that is, a support frame for storing insulators is pushed into a flat cylindrical body (sintering furnace). However, the horizontal sintering furnace usually causes the support frame to be inextensible. When different types of insulators are placed in layers on the support frame, the distance between the middle partitions is too small, which can easily lead to uneven heating of the insulators. In addition, the sintering furnace usually adopts a heating tube heating method, and the traditional support frame is fixed in position, which leads to uneven heating of the insulators when they are statically placed in the sintering furnace.
