The configuration involves placing the right unit and the left unit facing each other, allowing work to be carried out simultaneously from both sides!
The "Counter-Type Expanding Machine for Heat Exchanger Cooling Tubes" is a machine that performs tube expansion by inserting an expanding tool into the cooling tubes assembled and set on the tube sheet, allowing the outer diameter of the tube to be fitted into the holes of the tube sheet. The fixture for assembling heat exchangers is placed in the center of the machine, with the right unit (3-axis NC control: XYZ) and the left unit (2-axis NC control: XY) arranged oppositely to perform work simultaneously from both sides. Additionally, it minimizes distortion of the tube sheet after expansion. 【Features】 ■ Inserts an expanding tool into the cooling tubes assembled on the tube sheet for expansion ■ Fits the outer diameter of the tube into the holes of the tube sheet ■ Places the fixture for assembling heat exchangers in the center of the machine ■ Arranges the right and left units oppositely to perform work simultaneously from both sides ■ Capable of minimizing distortion of the tube sheet after expansion *For more details, please refer to the PDF document or feel free to contact us.
