Preparation machine of high-temperature structural ceramic

Abstract

The invention discloses a high-temperature structural ceramic preparation machine, which structurally comprises a placement box, a supporting plate, a workbench, a preparation box, a handle and a boxdoor, wherein the bottom of the placement box is welded to the top of the supporting plate, and the lower end of the supporting plate is welded to the upper surface of the workbench. According to theinvention, heat is conducted into a transmission pipe through a pipeline and is conducted through hot air of a conduction rod in a sealed mode, so that the outer side of a forming cavity is subjectedto high temperature more uniformly, and the overall calcining temperature of a ceramic sealing ring is increased; after an extrusion mechanism completely enters a box body, and an opening and closingplate is automatically closed, so that the high-temperature loss in the forming device is reduced; an extrusion round block is subjected to extrusion buffer adjustment through a spring, so that the extrusion round block is prevented from generating excessive extrusion force on the formed ceramic sealing ring; and a sliding outer ring abuts against the ceramic sealing ring through upward lifting ofan air cylinder and downward pressing of the sliding outer ring, and the ceramic sealing ring is prevented from falling off from the extrusion round block, so that the ceramic sealing ring is prevented from being embedded in the outer side of the extrusion round block.

Description

technical field [0001] The invention relates to the field of high-temperature structural ceramic equipment, and more specifically, relates to a preparation machine for high-temperature structural ceramics. Background technique [0002] Ceramic materials have high wear resistance, high temperature resistance and chemical corrosion resistance. At present, they have been applied to high-speed engine bearings, sealing rings and other components that require high speed and high matching precision. Carry out calcination and then solidify the finished product by extrusion, but in the process of calcination and extrusion molding of the ceramic sealing ring, when the heating mechanism inside the preparation machine heats the ring-shaped ceramic sealing ring, the overall heating degree of the ceramic sealing ring is different, At the same time, it is necessary to move the extrusion mechanism, resulting in heat loss on the outside of the ceramic sealing ring, reducing the degree of hea...

[0002] Ceramic materials have high wear resistance, high temperature resistance and chemical corrosion resistance. At present, they have been applied to high-speed engine bearings, sealing rings and other components that require high speed and high matching precision. Carry out calcination and then solidify the finished product by extrusion, but in the process of calcination and extrusion molding of the ceramic sealing ring, when the heating mechanism inside the preparation machine heats the ring-shaped ceramic sealing ring, the overall heating degree of the ceramic sealing ring is different, At the same time, it is necessary to move the extrusion mechanism, resulting in heat loss on the outside of the ceramic sealing ring, reducing the degree of heating of the ceramic sealing ring, resulting in a lower local calcination temperature of the ceramic sealing ring, affecting the overall molding of the ceramic sealing ring, and the ceramic sealing ring It is easy to expand after being exposed to high temperature, and excessive extrusion force will be generated with the extrusion mechanism inside the preparation machine. After the preparation is completed, the ceramic sealing ring is easily nested on the extrusion mechanism and it is difficult to take it out.
