Description

Technical Field

[0001] The utility model relates to the technical field of hole expansion, in particular to a hole expansion device. Background Art

[0002] The automobile radiator is an important part of the water-cooled engine. As an important component of the water-cooled engine cooling circuit, it can absorb the heat of the cylinder and prevent the engine from overheating. At present, during the production and processing of automobile radiators, the heat pipes and the mainboard are fixed by welding. In order to ensure the welding quality, after assembling the core, it is necessary to use a hole expansion device to expand the pipe opening of the heat pipe so that the pipe opening and the through hole on the mainboard fit better.

[0003] When the existing reaming device is reaming the heat dissipation tube, a worker is required to place the heat dissipation tube on a positioning station, and then press and fix the heat dissipation tube by a downward pressing fixing mechanism, and then reaming is performed by the reaming mechanisms on both sides. After the reaming is completed, the fixation needs to be released, and then the worker takes out the heat dissipation tube and places it in the set position. Only then can the heat dissipation tube to be reamed be placed on the positioning station, which makes the loading and unloading time longer, which undoubtedly increases the time required for reaming. In large-scale operations, the loading and unloading will definitely take up a lot of processing time, and therefore, the reaming efficiency of the heat dissipation tube will be reduced. For this reason, a reaming device is proposed. Utility Model Content
