Thin-wall steel tube bending machine

Abstract

The invention discloses a thin-wall steel tube bending machine which comprises a fixing key, a steel tube, a steel tube clamp, a hinge pin, a handle, a spring, an adjusting screw, a wheel seat, a spindle, a guide wheel, a rolling press wheel, a rotating disc and a tube bending module. The fixing key is embedded in the tube bending module, and the outer portion of the tube bending module is tightly connected with the steel tube. The steel tube penetrates through the steel tube clamp. One end of the steel tube is provided with a wheel seat, and the guide wheel and the rolling press wheel are fixedly mounted in the wheel seat. The adjusting screw is arranged at the top end of the wheel seat and fixedly mounted at the tail end of the handle. The handle is fixed through the hinge pin. The thin-wall steel tube bending machine can stably bend tubes, the cost is low, the bending requirements of workpieces of different sizes can be met, the application range is expanded, and tube forming consistency in the batched tube bending process can be guaranteed; and time and labor are saved, the bending angle of the tube can be conveniently adjusted, the production procedure is shortened, the production cost is lowered, and work efficiency is improved.

Description

technical field [0001] The invention relates to a pipe bending machine, in particular to a thin-walled steel pipe bending machine. Background technique [0002] With the development of society and the continuous progress of the manufacturing industry, pipe bends are widely used in refrigeration, machinery, chemical and other industries. The mass production of thin-walled steel pipe bends is generally cold-formed on a pipe bender. Due to the thin-walled The critical force for instability of steel pipe wall support is low, and deformation defects such as wrinkle often appear in the bending 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 highly heavy. [0003] The new type can perform the bending work ...
