It is mainly composed of base, oil cylinder, hydraulic station, flaring adjusting device, workpiece clamping device and electric control box. The electric control part adopts PLC control and touch screen display, so it is safe and reliable to operate.

The secondary flaring length device is driven by the motor reducer, chain wheel and chain to rotate the screw, so as to realize the secondary expansion, convenience and hydraulic locking of the lower limit block of different length workpieces.

Features and functions of vertical tube expander:

(1) The equipment can perform the functions of primary expansion, secondary expansion and three flanging at the same time.

(2) Tube expander body has enough strength and rigidity to ensure no deformation during long-term operation.

(3) The machining accuracy of all template holes should be controlled within 0.01mm.

(4) The equipment is equipped with buffer device when expanding the bell mouth to avoid wrinkling at the bottom of u-coil.

(5) Aluminum alloy fixture, easy to adjust, easy to expand and join products of different specifications.

(6) The expanding rod is made of spring steel, which has enough rigidity and strength; the expanding head is made of tungsten steel, the hardness of heat treatment can reach more than hrc85, the surface is ground and polished, the consistency error is less than 0.01mm, and the wear loss within 4 years under normal use condition is not more than 0.01mm.

(7) After the expansion, the fins of the evaporator are arranged evenly and orderly without distortion and skewness. It is convenient to adjust the bell mouth, the shape of flanging mouth is uniform and uniform, and the expansion force is uniform, and there is no crack or crack.

(8) The U-shaped bearing seat is easy to be assembled and disassembled, and the positioning is reliable and accurate.

(9) The hydraulic system has no leakage during normal operation.

(10) All mechanisms of the equipment shall ensure the safety and reliability in the process of installation, commissioning and normal operation, and ensure the personal safety of the operator when operating normally according to the equipment operation regulations.
