Abstract

The invention provides a pipe expander base structure and a pipe expander with the same. The pipe expander base structure comprises a base body, a rotational connecting structure and a rotating driving device. The rotational connecting structure comprises an inner ring and an outer ring which can be rotated relatively. The outer ring sleeves the inner ring. Gear teeth are arranged at the outer peripheral face of the outer ring. The inner ring is connected with the base body. The outer ring is used for being connected with a pipe expander body. The rotating driving device is arranged on the base body. The rotating driving device comprises a driving gear. The driving gear is meshed with the gear teeth so as to drive the outer ring to drive the pipe expander body to rotate. The pipe expanderbase structure solves the problem that the using reliability of a pipe expander base structure in the prior art is poor.

Description

technical field [0001] The invention relates to the field of tube expansion equipment, in particular to a tube expander base structure and a tube expander with the same. Background technique [0002] At present, tube expanders are widely used in the processing of heat exchangers for tube expansion operations. [0003] The tube expander in the related art includes a tube expander base structure and a tube expander body installed on it for performing tube expansion operations. Figure 4 As shown, it includes a base body 1 and a rotating connection structure 2 installed thereon. The rotating connection structure 2 has an inner ring 21 and an outer ring 22 that can rotate relatively. The driving gear 31 on the device 3 cooperates with the inner teeth to drive the inner ring 21 to rotate relative to the outer ring 22 , and then drive the tube expander body to rotate relative to the base body 1 . [0004] During the actual use of the tube expander, the applicant found that the tu...
