Problems solved by technology

The disadvantage of this structure is that this kind of pipe bender only has three pressure rollers and one bending roller, so it can only bend steel pipes at one angle at a time. For a steel pipe that requires multiple bending points, This kind of

Embodiment Construction

[0014] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. Such as figure 1 and figure 2 As shown, a multi-angle bending machine includes a workbench 1, a pressure roller 2, a bending roller 3 and a controller. The controller is a PLC controller. Each pressing roller is driven to rotate by a variable frequency motor fixed at the lower part of the workbench, and the lower end of each pressing roller is keyed with gears that mesh with each other, one of which is meshed with the driving gear on the reducer, and the reduction The converter is connected to the output terminal of the variable frequency motor.

[0015] The side wall of the workbench is provided with an adjustment wheel 4 for adjusting the lateral movement of the pressure rollers. By rotating the adjustment wheel, two adjacent pressure rollers can clamp steel pipes with different diameters.

Abstract

The invention relates to the technical field of pipe benders, in particular to a multi-angle bender which comprises a bench, press rolls, a bending roll and a PLC (programmable logic controller). The press rolls are sequentially disposed at the top of the bench. Adjusting wheels for adjusting transverse movement of the press rolls are arranged on one side wall of the bench. The bending roll is in sliding connection with a guide on the bench. The bending roll is driven to move on the guide by a step motor disposed on one side of the bench. A first position sensor and a second position sensor are arranged on one side of the guide. An output end of the PLC is connected with a signal end of the step motor. A third sensor is arranged between two adjacent pairs of press rolls. The multi-angle bender is simple in structure and low in manufacturing cost. The motor controls the position of the bending roll on the guide to obtain required bending angles. Different bent angles can be made at different positions on one steel pipe by the multi-angle bender, and work efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of pipe bending machines, in particular to a multi-angle bending machine. Background technique [0002] At present, when manufacturing the skeleton on the plastic greenhouse, it is necessary to bend the round pipe to a certain arc shape. In the prior art, there is a hydraulic steel pipe bending machine, which mainly includes a turntable mechanism for bending steel pipes, a turntable travel mechanism and a turntable. The stroke control mechanism bends the steel pipe through the rotation of the turntable. According to the different bending angles required by the steel pipe, the turntable is controlled to rotate at a corresponding angle to achieve the purpose of bending the steel pipe. After the bending is completed, the turntable returns to the initial position. The disadvantage of this structure is that this kind of pipe bender only has three pressure rollers and one bending roller, so it can only bend steel ...
