Abstract

The invention discloses an air protection heating brazing furnace, comprising furnace body and welding room constituted by furnace. The welding room is divided into a group of control regions with different temperature. In each temperature control region internal thermal cycling fan, temperature sensor, electrical heater and temperature controller are set. Preheated protection air is connected with wind cavity of internal thermal cycling fan through pipes so that the internal thermal cycling fan with uniform temperature and protection air is set above the whole welding room and electrical heaters are set above and under workpeice properly. The data received by temperature controller from the temperature sensor is compared with setting parameters and the temperature controller controls electrical heaters in all temperature controlling regions. The invention can heat the brazing region in furnace accurately so that the temperature in the whole brazing region is uniform, the protection air is uniform and the workpeice welding quality is high.

Description

1. Technical field [0001] The invention relates to a component in an intermittent gas shielded brazing furnace, in particular to a gas shielded heating brazing furnace. 2. Background technology [0002] The intermittent gas shielded brazing furnace is a kind of equipment for effectively connecting the various parts of the aluminum heat exchanger. It is welded by using the characteristic that the melting point of the aluminum brazing material Al-Si alloy is lower than the melting point of the metal material of the part AL. Most of the existing brazing furnaces are continuous type. The brazing furnace with this structure has a large installed capacity and is suitable for processing large quantities of workpieces. However, the flexibility is poor, and it is difficult to meet the requirements for workpieces of different specifications and types. When changing the specifications and types of workpieces, it is difficult to adjust each parameter and the adjustment period is long. ...
