Description

Technical Field

[0001] The utility model belongs to the technical field of the production and processing of molybdenum disilicide heating elements, and particularly relates to a high-temperature bending device for molybdenum disilicide. Background Technique

[0002] Molybdenum disilicide material belongs to cermet and has soft plasticity above 1000°C. The processing of various shapes of molybdenum disilicide is completed under high-temperature conditions.

[0003] The existing molybdenum disilicide bending uses the whole material rod to be energized to reach a high-temperature state, and then a bending machine is used for bending operations. Since the resistance of the molybdenum disilicide element is small, the power-temperature change of the element caused by the voltage fluctuation during the energized bending process is likely to cause bending cracks and overheating. Especially for longer product specifications, the two ends of the molybdenum disilicide straight rod are energized, and the overall temperature is maintained at a high-temperature state. After processing, the shapes of the bent part and other parts are not standardized, and local stretching is likely to occur during the bending process. For this reason, we propose a high-temperature bending device for molybdenum disilicide to solve the above-mentioned problems. Summary of the Utility Model
