Abstract

The invention belongs to the technical field of pipe expanding equipment, and provides a calibration mechanism of a pipe expander. The calibration mechanism comprises a pressing device and a clamping device, the clamping device is provided with an abutting plate, and the pressing device is provided with a pressing plate capable of moving towards the abutting plate in the X-axis direction; and the abutting plate is provided with clamping arms for clamping the abutting plate from the two sides in the Y-axis direction, and the calibration mechanism is arranged on the pipe expander and can calibrate a plurality of heat exchange pipes placed on the pipe expander in batches in the X-axis direction and the Y-axis direction, so that the heat exchange pipes can be aligned with expansion rods on the pipe expander in the Z-axis direction. According to the invention, the heat exchange pipes in batches only need to be grabbed and placed on the pipe expander through mechanical arms, the calibration mechanism can conduct calibration and positioning treatment on the heat exchange pipes in batches, the heat exchange pipes in batches are matched with all expansion rods on the pipe expander in position, and the working efficiency of the pipe expander can be improved.

Description

technical field [0001] The application belongs to the technical field of tube expanders, in particular to a tube expander and its calibration mechanism. Background technique [0002] The heat exchange tube is one of the elements of the heat exchanger, which generally has a U-shaped pipe structure. During the processing of heat exchange tubes, tube expanders are usually used to process the heat exchange tubes to better contact the fins, thereby ensuring the heat exchange effect of the heat exchanger. In general, the tube expander needs to expand and flare the heat exchange tubes. Wherein, the tube expansion treatment is to insert an expansion rod with a sphere into the heat exchange tube, so as to increase the tube diameter, and then realize tube expansion of the heat exchange tube body. The flaring treatment is to insert a flaring piece of a specific size into the nozzle of the heat exchange tube, so that the diameter of the nozzle at the nozzle is further increased, and t...
