More Information
Summary:The utility model belongs to the field of pipe expanding dies, and particularly relates to a novel pipe expanding device which comprises a base. A driving assembly is arranged outside the base, the lower end of the driving assembly is connected with a reset assembly, and the upper end of the base is connected with a pipe expanding mold assembly. Through the structural design of the driving assembly, when a hydraulic cylinder breaks down, a screw is detached, an output rod is separated from a pressing plate, and a balancing weight is placed on a fixing frame, so that the pressing plate can be driven to move downwards, pipe fittings can also be expanded, shutdown caused by faults of driving parts such as the hydraulic cylinder is avoided, and the working efficiency is improved. And a limiting piece has the functions of limiting a balancing weight and preventing a wedge block from being stressed unevenly, so that the problems that an existing pipe expanding mold is mostly driven in a hydraulic mode during use, a
