Vacuum high temperature brazing furnace with rapid cooling

Abstract

The invention discloses a vacuum high temperature brazing furnace with rapid cooling. The vacuum high temperature brazing furnace with rapid cooling comprises a furnace body, a sealing door is arranged on one side of furnace body, and the furnace body is internally provided with a brazing chamber, a heating chamber and a cooling circulation chamber. The brazing chamber is internally provided witha brazing platform, a heating chamber with an open upper end is arranged under the brazing platform, the cooling circulation chamber is arranged above the brazing platform, and the cooling circulationchamber is internally provided with two or more groups of semiconductor cooling components. Cold conducting fins are connected with a grid plate, heat conducting fins are connected to one ends of circulation pipes, and the other ends of the circulation pipes are connected with the bottom of the brazing chamber in a communicating mode. A vacuum chamber is arranged above the furnace body. Accordingto the vacuum high temperature brazing furnace with rapid cooling, temperature and noise are reduced effectively, noise is reduced, and the working environment is improved; and meanwhile, recycling of heat in the high temperature brazing furnace is realized.

Description

technical field [0001] The invention relates to an industrial furnace, in particular to a rapidly cooling vacuum high-temperature brazing furnace. Background technique [0002] Brazing furnace is a kind of equipment used for metal brazing and bright heat treatment. It is suitable for mass production of small and medium-sized stainless steel parts (tableware, knives, hardware, etc.), such as bright quenching and tempering of martensitic stainless steel, and bright annealing of austenitic stainless steel. The vacuum high-temperature brazing furnace is the most commonly used one of the existing brazing furnaces, with high working efficiency and good brazing effect. [0003] The brazing furnace in the prior art has the following problems in use: 1. The vacuum degree is relatively poor, and the vacuum gauge is easily polluted at the same time. Due to the high-temperature calcination and brazing process, waste gas will be generated, which is easy to pollute the vacuum gauge; 2. ...

Problems solved by technology

[0003] The brazing furnace in the prior art has the following problems in use: 1. The vacuum degree is relatively poor, and the vacuum gauge is easily polluted at the same time. Due to the high-temperature calcination and brazing process, waste gas will be generated, which is easy to pollute the vacuum gauge; 2. In the prior art, the air-cooling system is generally used for cooling treatment. The noise generated by the air-cooling system is relatively large. Although the noise reducer will be enhanced to reduce the noise, the noise is still relatively large, causing noise pollution, and the entire workshop is buzzing. 3. The problem of heat recovery and utilization, the cooling method in the prior art is difficult to effectively recover heat, resulting in heat loss
