Multifunctional transformer pipe bending machine

Abstract

The invention discloses a multifunctional transformer pipe bending machine which comprises a frame formed by a frame upper plate, a frame lower plate and a frame side plate. A driving wheel and a driven wheel are arranged in the frame, wheel teeth of the driving wheel and the driven wheel are matched with each other, the driven wheel is connected with the frame upper plate and the frame lower plate through a driven wheel shaft, the driving wheel is connected with the upper plate, the frame lower plate frame and a bottom plate through a driving wheel shaft, a limiting rod is arranged on the bottom plate, adjusting blocks are arranged at the connecting portions of the two ends of the driven wheel shaft, the frame upper plate and the frame lower plate, two fixing plates are arranged on the bottom of the frame lower plate, the two ends of a supporting shaft are erected on the fixing plates and are provided with supporting shaft sleeves, a supporting roller is arranged on the supporting shaft and is in contact with the bottom plate in a rolling mode, and an operation rod is connected to the frame side plate. The multifunctional transformer pipe bending machine is simple in operation and can be suitable for multi-specification multi-point multi-angle bending, practical using shows that the deformation amount of a copper pipe after bending is not larger than 5%, and the requirement of primary thin-wall copper pipe bending in the transformer industry can be met completely.

Description

technical field [0001] The invention relates to equipment for transformer production, in particular to a pipe bender used for bending copper pipes connected to the primary line outside the transformer. Background technique [0002] With the acceleration of the urbanization process, the demand for epoxy resin cast dry-type transformers is increasing, but as the copper tube connected to the external primary line of the transformer, there are many specifications coexisting, and the wall thickness is very thin, ranging from 0.8 to 1 mm. etc., and the bending angle and quantity are not the same. All of the above situations often cause serious deformation or even cracking of the copper tube after bending, thus causing safety hazards to the transformer. In view of the above situation, there is an urgent need to develop a machine that can make thin copper tubes bend without obvious deformation, and is suitable for simultaneous use of multiple specifications, and can simultaneously m...
