Four-head automatic brazing device for aluminum cooler

Abstract

The invention discloses a four-head automatic brazing device for an aluminum cooler. The four-head automatic brazing device further comprises a flame gun mounting table and workpiece clamping devices;two groups of workpiece clamping devices are arranged; the aluminum cooler is fixed to the workpiece clamping devices; the flame gun mounting table comprises a moving mechanism, a flame gun componentand a temperature control mechanism; the moving mechanism is installed on a pedestal; the temperature control mechanism is fixed to the bottom of the pedestal; the flame gun component communicates with the temperature control mechanism; four independent flame nozzles are simultaneously adopted for heating a workpiece so as to guarantee the consistency and uniformity of the temperature of outputted flame; moreover, the temperature of the workpiece is monitored at any time in a heating process so that the workpiece can be uniformly heated in a machining process; after reaching a welding temperature, a brazing wire enters a welding seam after being molten and heating is stopped immediately, so the welding reliability can be guaranteed, and the tube wall is also not burned through.

Description

technical field [0001] The invention belongs to the technical field of automatic welding, and in particular relates to a four-head automatic brazing device for an aluminum radiator. Background technique [0002] The brazing of the existing aluminum radiator water pipes is basically manual welding, the processing environment of the workers is relatively harsh, the product quality is unstable, and there are often cases of missing welding or insufficient welding sealing. In addition, workers have been operating in a high-heat and high-brightness environment for a long time, which is prone to fatigue, and it is difficult to guarantee long-term processing operations, and some equipment uses automatic welding with flame heads, and heats the aluminum radiator water pipes through the circular motion of the flame head Welding, but because the tube wall of the radiator is thin and the melting point of aluminum is low, it is easy to cause excessive heating of the workpiece or insuffici...
