Abstract

The invention discloses a pipe bender. The pipe bender comprises a fixed disc, and the fixed disc comprises a top disc and a bottom disc; ceramic pieces are fixedly welded at the middle part of the top of the bottom disc and the middle part of the bottom of the top disc; ceramic pillars are fixedly welded at the middle parts of the tops of the ceramic pieces; first butt joint holes are formed in the top and the bottom of the outer side of the fixed disc at equal intervals; first coils are connected in inner cavities of the first butt joint holes in an interpenetrating manner; a mounting bolt is connected in the middle part of the top of the fixed disc in an interpenetrating manner; a force arm plate is connected to the top of the outer side of the mounting bolt in a sleeving manner; and abending mechanism is arranged at the bottom of the force arm plate. According to the pipe bender, a metal pipe is bent when atoms in the metal pipe are in an extremely active state, bent parts can becompensated under irregular motion and are more smooth and natural, shaping after bending in a burning state is more stable, the bent parts are not liable to rebound, and error values of bent corner parts are decreased.

Description

technical field [0001] The invention relates to the technical field of pipe bending, in particular to a pipe bending machine. Background technique [0002] At present, in industries such as industrial production and construction industries, various metal materials are often used, and the requirements for the shape and curvature of metal materials required for the production of different products or in different locations are also different, and With the continuous progress and development of science and technology, both the quality of metal materials and the requirements for product quality are getting higher and higher. Among them, there is equipment for bending metal materials, that is, pipe benders, which are not only It can bend hollow metal pipes at a certain angle, and can also perform deformation work on some solid metal materials. The existing pipe bending machines include manual, electric and air pressure. [0003] For example, the Chinese patent discloses "a pneum...
