Abstract

The invention discloses a steel pipe heating space bending method and a heating space pipe bending machine. A steel pipe clamping device is pushed to move horizontally by using a hydraulic propelling cylinder, wherein one end of the steel pipe is clamped by a steel pipe propelling chuck; the other end of the steel pipe is clamped by a rocker arm chuck; a steel pipe bent part is heated by using a heating device; temperature of the steel pipe bent part is measured by using a temperature control system; in comparison with a set temperature value of the steel pipe bent part corresponding to a set bent pipe semi-diameter, when the temperature of the steel pipe bent part reaches the set temperature value, the hydraulic propelling cylinder is adjusted in time and used for pushing a steel pipe and / or a rocker arm to bend along a rocker arm rotation shaft according to a set rocker arm semi-diameter; a first bent head is bent by automatically stopping after reaching a set bent angle; the steel pipe is rotated by a steel pipe rotating device; the bending step of the first bent head is repeated after reaching a set rotation angle, so that the bending of the rest of bent heads is achieved; and finally, the precise space bending of the steel pipe is achieved.

Description

technical field [0001] The invention relates to a space multi-dimensional pipe bending method and a pipe bending device, in particular to a steel pipe hot-simmering space bending method and a pipe bending device. Background technique [0002] In aerospace, nuclear industry, petrochemical, shipbuilding, electric power, container manufacturing, steel structure and other industries, it is necessary to use a large amount of space to bend pipes. Under the current technical level, the steel pipes can only be bent in a plane and then welded. Processing, or use three-dimensional pipe bending equipment for bending. Among them, the hot simmering pipe bending equipment existing on the market is mainly suitable for plane bending, and it is more difficult for 3D space bending of steel pipes. [0003] After searching, it is found that the application number is "2011203362078" and the name is "three-dimensional pipe bending machine". The device transports the pipeline according to preset...
