Abstract

The invention discloses a round tube bending machine which comprises a machine body, a force transfer arm and a drive gear, wherein a fixed die is arranged on a projection at the upper part of the machine body, the force transfer arm is hinged with the machine body, one end of the machine body, which is far away from the fixed die, is provided with a locating shaft, the drive gear and the machine body are hinged with the locating shaft, a drive handle is fixedly connected onto the drive gear, the force transfer arm is of a bending structure and is divided into a vertical section and a horizontal section, the upper part of the vertical section of the force transfer arm is provided with a movable die, and the horizontal section of the force transfer arm is provided with a gear which is meshed with the drive gear. The machine can conveniently bend a round tube, is simple to operate, and is also lower in production cost.

Description

technical field [0001] The invention relates to a metal pipe processing machine, in particular to a round pipe arc pressing machine. Background technique [0002] In the modern machining process, a wide variety of processing types are often involved. For some commonly used processing methods, some pre-processing and pre-deformation methods are also required. For example, in the welding process of metal pipes, due to the Welding between the two surfaces, the contact point is small, usually one of the metal tubes needs to be pre-deformed to increase the contact area of ​​the two tubes and improve the welding effect. For this operation, the existing processing enterprises often use arc punching, CNC Plasma arc cutting machine tools are used to complete the arc shape required for welding the thick tube and thick-skinned tube head, but for small-scale enterprises, the number of welded tubes is not large, and the CNC equipment is expensive. It can only be processed with a grinder...
