Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger coiling tubes, in particular to a rolling spiral tube forming device with axial limiting. Background Art

[0002] The coiled tube of the heat exchanger (also called spiral tube or spiral coil) is a key component for transferring heat in the heat exchanger. It is usually made of metal and wound in a spiral shape to increase the heat exchange area. The corresponding coiled tube forming device is needed in the production process. When the spiral tube is curled and formed, it is guided and curled with the help of a guide wheel to make the originally horizontal steel strip curled into a circle. For example, the authorized patent CN202321460703.3 is a spiral tube cold bending device, which can solve the forming problem well. However, if coiled tubes of different diameters are processed, the versatility still needs to be improved, and the clamping seat is located at the rear, which is inconvenient to operate. If it is not locked, there are still certain safety issues. Therefore, based on the above problems, a special forming device is designed. Utility Model Content
