Tube bending and forming mechanism

Abstract

The invention relates to a tube bending and forming mechanism which comprises a tube discharging mechanism and a tube bending mechanism, wherein the tube discharging mechanism comprises a shaft, the shaft is sleeved with roller wheels which can move along the shaft vertically, and annular concaved surfaces matched with a tube blank are formed in the roller wheels; the tube bending mechanism comprises a rotating cylinder, an outer circle of the cylinder is processed to be a spiral groove corresponding to the tube blank, and a clamp for fixing the end part of the tube blank is arranged at the lower end of the tube bending mechanism; and the moving speeds of the roller wheels on the shaft correspond to a rotating speed of the cylinder. According to the tube bending and forming mechanism, by means of effective matching of the tube discharging mechanism and the tube bending mechanism, compared with a conventional tube bending mechanism, continuous production is realized; and in order to realize smooth and fast production, the tube discharging mechanism can be inclined at a certain angle, so that tubes can be smoothly discharged.

Description

technical field [0001] The invention relates to a bending pipe forming mechanism, specifically, it is applied to forming a circular pipe such as a pressure equalizing ring from a straight pipe. Background technique [0002] In many occasions, it is necessary to use large-diameter pipe circles, such as anti-halo rings on power lines. Traditional anti-halation rings are generally welded by multiple arc circles, which makes the overall dimensional accuracy poor and affects the anti-halation effect. In addition, this anti-halation ring is complicated to manufacture and requires multiple welds. [0003] For this reason, the patent application number 2009100284318 provides a 360 ° pipe bender, which bends the pipe end when the straight pipe is fed, so that the straight pipe is plastically deformed according to the set center and radius. In order to bend the pipe into a complete 360°, the pinch roller group, guide roller 1, and guide roller 2 are respectively inclined to form a s...

Problems solved by technology

[0004] The 360° pipe bending machine provided by the above patent application can only form one round tube at a time. After the round tube is formed, the tube must be broken before the next round tube can be formed. The processing lacks continuity and the production efficiency is low, so it cannot meet the needs of large-scale production. The production demand needs to be further improved
