Description
Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, in particular to an internal thread pipe forming machine with a replaceable core head. Background Art
[0002] Internally threaded tubes are also called dry steam tubes, internal rib tubes or internal fin tubes. In central air conditioners, they are mainly used in dry evaporators. During heat exchange, the water outside the tube is cooled by the refrigerant that evaporates and expands inside the tube; they are also used in heat exchangers for household and commercial air conditioners or for high heat pipes.
[0003] When processing internal threaded pipes, the core head needs to be fixed in size first, so the fixation of the core head is very important. Traditional internal threaded pipe processing generally fixes the core head, but this brings inconvenience. If you want to process and form core heads of multiple sizes, you will not be able to operate it. You can only disassemble the device to replace core heads of different sizes, which will slow down the progress of internal thread processing. Even improper operation will cause errors and make the product scrapped. For this reason, we propose an internal threaded pipe forming machine with replaceable core heads. Utility Model Content
