Round steel pipe bending machine

Abstract

The invention belongs to the field of steel pipe machining, and relates to a circular steel pipe bending machine which comprises a fixedly-installed base, a fixing module is fixedly installed on the base, and a bending module is arranged on the side, facing the fixing module, of the base. An auxiliary module making circular motion in the vertical direction of the geometric center is fixedly installed on the side, opposite to the fixing module, of the bending module and located on the base, and a clamping module is installed on the side face of the auxiliary module. When a short steel pipe is bent, in order to prevent the steel pipe from deflecting in the bending process, the steel pipe can be further reinforced through the fixing module and the clamping module. In the bending process, condensate can be sprayed to cool a steel pipe, and the situation that in the bending process, the bending effect is affected due to the fact that the temperature is too high is prevented. In the steel pipe bending process, external force does not need to be manually applied, and labor force is saved.

Description

technical field [0001] The invention belongs to the field of steel pipe processing, in particular to a round steel pipe bending machine. Background technique [0002] Commercially available steel pipes are generally straight pipes. When using a curved steel pipe of a specific specification, the straight pipe needs to be bent. At present, the bending method is generally to first heat the part of the straight pipe to be bent to a certain temperature by gas welding. , Bending manually or with the help of tools is inefficient, the bending angle is difficult to control, and the steel pipe is easy to crack after bending. Therefore, it is necessary to design a round steel pipe bending machine, which mainly aims at and achieves the following points: [0003] ①. When bending shorter steel pipes, in order to prevent the steel pipes from deflecting during the bending process, the steel pipes will be further reinforced by the fixing module and the clamping module. [0004] ②. During t...
