Problems solved by technology

The bending construction of traditional galvanized steel pipes is mainly based on manual bending with a pipe bender. Due to the high rigidity of galvanized steel pipes, manual bending is time-consuming and laborious, and the size and angle of the bent pipe fittings cannot be accurately controlled, so it can only be constructed by experience. This leads to the uncontrollable quality of the bent pipes, and it often happens that the pipes are flattened due to the uneven force of the workers and cannot be used.

Abstract

The invention provides a steel pipe rapid bending device and method. The device comprises a machine tool, and a horizontal working disc arranged on a machine tool work platform. A fixed supporting wheel die is arranged on the machine tool work platform, and a bending die and a rotary supporting wheel die are arranged on the work disc and can rotate along with the work disc. The bending die comprises an arc-shaped groove, and the rotary supporting wheel die is provided with an arc-shaped concave face. The fixing positions of the bending die and the rotary supporting wheel die on the work disc are selected according to different steel pipe diameters, one end of a to-be-bent steel pipe abuts against the fixed supporting wheel die, the other end of the to-be-bent steel pipe abuts against the arc-shaped concave face of the rotary supporting wheel die, the to-be-bent part of the steel pipe is embedded into the arc-shaped groove of the bending die, and the work disc rotates anticlockwise to bend the steel pipe. Steel pipe bending operation is simple, forming is rapid, cost is low, equipment can be reused, and the bend-formed pipe is precise in size and angle.

Description

technical field [0001] The invention relates to the construction technical field of pipe fitting processing in electrical installation, in particular to a steel pipe rapid bending device and a bending method thereof, in particular to equipment and construction methods for rapid bending and forming of large quantities of galvanized steel pipes. Background technique [0002] In the construction of building electrical engineering, galvanized steel pipes are widely used as threading pipes. According to the needs of wiring, galvanized steel pipes need to be processed and bent. Usually, thousands of galvanized steel pipes need to be bent in one project. The bending construction of traditional galvanized steel pipes is mainly based on manual bending with a pipe bender. Due to the high rigidity of galvanized steel pipes, manual bending is time-consuming and laborious, and the size and angle of the bent pipe fittings cannot be accurately controlled, so it can only be constructed by ex...
