Description

Technical Field

[0001] The utility model relates to the technical field of sintering furnaces, in particular to a pusher which is convenient for unloading and loading a sintering furnace. Background Art

[0002] A sintering furnace is a device used for the sintering process. In the metallurgical industry, it is often used to make powder sintered cutting tools, high-temperature alloys, cemented carbide and other blank materials. The materials prepared by high temperature and high pressure usually have higher strength, greater hardness, better high-temperature stability and good organizational stability.

[0003] At present, the main components of a sintering furnace include a furnace body, a furnace door, a heating mechanism, a temperature control device and a built-in swing rack. The furnace body forms a sintering cavity that is through-through from front to back and closed from top to bottom and left to right. The heating mechanism is used to heat the sintering cavity, and the temperature control device is used to control the temperature inside the furnace. The built-in swing rack is fixed in the sintering cavity, which forms several pallet placement layers for workers to place pallets with workpieces one by one into the corresponding pallet placement layers.

[0004] With this built-in swing frame and pallet structure, workpieces can only be loaded and unloaded into and out of the furnace chamber one by one by using the pallet, resulting in low loading and unloading efficiency and delays in the use of the sintering furnace. If the built-in swing frame is improved to a structure that can be used to unload the sintering furnace, the built-in swing frame and the pallet can be unloaded from the sintering furnace together, thereby improving the loading and unloading efficiency of the workpieces. However, there is still a lack of a structure that can be used with a removable built-in swing frame to support the built-in swing frame when unloading from the sintering furnace.
