AI Technical Summary
In the existing technology, the position and angle of the heat exchange tubes need to be manually adjusted during the heat exchanger winding process, which is time-consuming and labor-intensive, and can easily cause the heat exchange tubes to bend and deform. Real-time adjustment is not possible, which affects the performance of the equipment.
The tube winding machine is used as an auxiliary trolley. The position of the heat exchange tube coil is adjusted by the support components and lifting mechanism. Combined with the diagonal bracing components, the stability is improved, and the automatic adjustment and support are realized.
It enables automated adjustment of the position and angle of the heat exchange tubes, reduces manual operation, improves the efficiency and stability of the tube winding process, and avoids bending and deformation of the heat exchange tubes.
