Abstract

The invention relates to a thin-walled steel pipe bending machine. The thin-walled steel pipe bending machine comprises a pipe bending machine body, a rotary disc is arranged at the lower end of the pipe bending machine body, a steel pipe clamp is arranged on the pipe bending machine body, a steel pipe is placed in the steel pipe clamp, a roller base is arranged at the other end of the steel pipe, a rolling pinch roller and a guide roller are arranged on the roller base, handles which are connected through adjusting screws are arranged on the roller base, a pipe bending module is arranged on the pipe bending machine body, and a spindle which is connected in a key joint mode is arranged on the pipe bending module. The thin-walled steel pipe bending machine is simple in structure, and convenient to use, improves the strength and the bearing capacity of the steel pipe, reduces the uneven degree of the speed of a flow medium, vortex, dirt accumulation at the bending positions and the like in the steep pipe, and the qualification rate of products is improved.

Description

technical field [0001] The invention relates to a thin-wall steel pipe bending machine. Background technique [0002] Bending pipes are widely used in refrigeration, machinery, chemical and other industries. The mass production of thin-walled steel pipe bends is generally formed by cold bending on a pipe bending machine. Deformation defects such as shrinkage and wrinkle often appear in the part. These defects not only weaken the strength of the steel pipe and reduce its bearing capacity, but also easily cause uneven velocity of the flowing medium in the pipe, generation of eddy currents, and accumulation of dirt in the bending part, etc., which affect the normal use of the elbow. The biggest difficulty must be given great attention. During the bending process of the pipe, the resultant force of the tensile stress of the outer edge and the compressive stress of the inner edge acts on the middle, resulting in the increase of the diameter of the bending part of the pipe on th...
