Abstract

The invention provides a hot air circulation oven, which comprises a thermal insulation box, a thermal insulation door, a driving motor, a temperature measuring tube and at least two U-shaped heating tubes, and the thermal insulation door is rotatably installed at the front opening of the thermal insulation box through a hinge There is a "door"-shaped cavity in the heat preservation box, and the gas can be heated in the heat preservation box by heating the gas in the "door"-shaped cavity and driving the impeller through the driving motor. The hot air circulation oven has good heating uniformity and high temperature control precision.

Description

technical field [0001] The invention relates to an oven, especially an oven used for heat treatment of small devices. Background technique [0002] Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. Metal heat treatment is one of the important processes in mechanical manufacturing. By changing the microstructure inside the workpiece or changing the chemical composition of the workpiece surface, it can endow or improve the performance of the workpiece. With the development of science and technology, people's requirements for heat treatment process are also increasing. The existing furnace temperature uniformity is low, which cannot meet the heat treatment requirements for high-precision objects. The oven has a large volume and high cost and is not suitable for heat treatment of ...
