FIELD: process engineering.
SUBSTANCE: set of inventions relates to metal forming and can be used for producing bumper beam by bending. Proposed computer-controlled device can configure bumper beam from various lengthwise sectional rods during rolling. Device bending workstation comprises main roll in tangential contact with continuous beam along the level of lines and moving part designed to press continuous beam to said main roll at the distance that allows partial grip for bend formation. Note that actuating mechanisms allow adjusted transfer of said moving part at least partially, around main bending roll side between first and second positions to produce multiple shapes in continuous beam in its lengthwise direction. In compliance with one version, proposed device comprises also synchronised cutting device to allow, after cutting continuous beam into parts, larger bend compared with central parts of the beam separate parts.
EFFECT: higher quality.
