Electromechanical pipe bender ИВ3428П can be used in boiler and shipbuilding industries, in assembly billets, in the installation of water and gas pipelines, as well as in construction and installation sites of industrial and civil construction.
Pipe bending machine is designed for bending pipes in a cold state with a mandrel and without it by winding a pipe onto a bending roller with a minimum bending radius of 1.5 pipe diameters and a maximum bending radius of 320 mm.
Currently, for this pipe bending machine, a motor control scheme is used via a frequency drive, which allows you to control the bending process smoothly, at different bending speeds, with great precision working out the set parameters. The accuracy of the bending angle of 0.3-0.5 degrees (with repeated bends). The control panel based on the controller with the LCD indicator has a more advanced “user menu”: “Manual” and “Automatic” operating modes, “Program” operating mode – according to the specified program of sequential bends (up to 8 programs with 8 bending angles in each) .
Mandrel is used to reduce the formation of ovality and corrugations. According to GOST 17380-2001, the ovality is not more than 6%. It is possible to bend without a mandrel, if high requirements are not imposed on the shape of the pipe section in a bent section or the ratio of the wall thickness to its diameter is more than 0.1.
When bending pipes, it is necessary to take into account their springiness (is a consequence of the composition of the pipe and is determined empirically).
