Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature electric furnace industry, in particular to a material loading platform rotating structure of a degreasing sintering furnace. Background Art

[0002] Debinding and sintering furnace is a key equipment used in the powder metallurgy process, mainly used to complete the two important steps of debinding and sintering. Debinding refers to the process of removing the added lipid substances in the pressed green body before sintering, usually by heating to near the volatilization point of the lipid to volatilize the lipid substances. Sintering is to consolidate the debinded powder at high temperature to form a product with the required properties.

[0003] The existing HTCC sintering furnace adopts static sintering, where the material tray is placed at the bottom of the furnace and sintered motionlessly. In order to enable all the material trays on the entire loading platform to rotate continuously during the debinding sintering process, the product can be evenly exposed to the atmosphere and the temperature can be more uniform. In view of this, we propose a rotating structure of the loading platform of the debinding sintering furnace. Utility Model Content

[0007] An active cavity is provided in the inner cavity of the loading platform.

[0008] Preferably, an extrusion block is slidably connected in the movable cavity, and the extrusion block penetrates the outer wall of the loading platform. When the material is placed on the loading platform, the extrusion block protruding from the loading platform is forced to be squeezed downward.

[0009] Preferably, the extrusion block is fixedly connected to a folding plate, and a sliding column is slidably connected between the extrusion block and the folding plate, and the downward pressure of the extrusion block drives the folding plate to slide toward the bottom.

[0010] Preferably, the sliding column is fixedly connected to the bottom wall of the inner cavity of the loading platform, and the sliding column is elastically connected to the folding plate through a spring, and the spring realizes the downward pressing and resetting activities of the folding plate.

[0011] Preferably, an outer wall of the folding plate is provided with an oblique groove, in which a sliding rod is slidably connected, and when the folding plate moves downward, the sliding rod slides obliquely upward along the oblique groove.

[0012] Preferably, the sliding rod is fixedly connected to a hinge plate, and the hinge plate is rotatably connected in the arc groove via a connecting shaft. The hinge plate is fixedly connected to a clamping block, and the sliding of the sliding rod drives the flipping of the hinge plate, and the rotation of the hinge plate drives the clamping block to gather inward to achieve a limiting effect.

[0013] The utility model provides a rotating structure of a loading platform of a degreasing sintering furnace. It has the following beneficial effects:

[0014] (1) The rotating structure of the loading platform of the degreasing sintering furnace is provided with a high-temperature flat thrust bearing. The loading platform is designed on the high-temperature flat thrust bearing, and the bearing is placed in a water-cooling structure to avoid high-temperature jamming. Then the shaft on the water-cooled magnetic fluid and the loading platform are fixed.

[0015] (2) The rotating structure of the loading platform of the degreasing sintering furnace is equipped with a gravity clamping device. When the material placed on the loading platform rotates, the material is pressed downward against the extrusion block. The downward pressure of the extrusion block drives the folding plate to slide to the bottom. During the downward movement of the folding plate, the sliding rod slides obliquely upward along the inclined groove. The sliding of the sliding rod drives the hinged plate to flip. The rotation of the hinged plate drives the clamping block to gather inward, which can adapt to the needs of different materials and loads, thereby ensuring that the material remains stable during the rotation process.
