Abstract
Description
Technical Field
[0001] This utility model belongs to the field of brazing equipment technology, specifically relating to a brazing machine that maintains the cleanliness of its internal cavity. Background Technology
[0002] Brazing is a method of joining workpieces by using a filler metal with a lower melting point than the base metal, heating the workpiece and filler metal to a temperature higher than the filler metal's melting point but lower than the base metal's melting temperature, and using the liquid filler metal to wet the base metal, fill the joint gap, and diffuse with the base metal. A brazing machine is a device that provides the necessary energy to achieve this process, melting the filler metal through different heating methods to complete the welding.
[0003] In existing brazing processes, taking liquid cooling plates for new energy vehicles as an example, the material is mostly aluminum alloy, and the main process is nitrogen continuous brazing, using single or double composite plates with brazing filler metal on the surface. Due to the presence of an oxide film on the surface of the brazing filler metal and its poor fluidity, flux needs to be sprayed onto the surface of the brazing filler metal to remove the oxide film and enhance the fluidity of the brazing filler metal. The 3-series aluminum alloy composite material is changed from a conventional composite material to a pre-embedded flux material to reduce the introduction of flux during brazing. On the other hand, when spraying flux onto the 6-series aluminum alloy composite material, the weight of flux on the surface of the part is controlled, and as little flux as possible is sprayed while meeting the brazing requirements, so as to meet the cleanliness control requirements.
[0004] A hydrogen-oxygen brazing machine, disclosed in patent publication number CN221064746U, includes a base and a drive plate. The drive plate is located at the top of the base, and one side of the drive plate is connected to a spring. The drive plate is connected to a welding station, which is fixedly mounted on the top of the base. Several sliding clamps are provided on the welding station, and the sliding clamps are also connected to the drive plate. A support frame is installed at the top of the base, and a lead screw is installed inside the support frame. The top of the lead screw is connected to a motor. A lifting platform is located on one side of the support frame and is connected to the lead screw. One side of the lifting platform is connected to a gas pipe, and a welding torch is installed at the bottom of the lifting platform. During the brazing process, welding slag and debris easily fall and accumulate, which not only affects the cleanliness of the work area but may also adversely affect the operation of the equipment and increase manual cleaning costs.
