STRETCHING AND BENDING APPARATUS WHICH BENDS A FORMED BEAM AT A PREDETERMINED CURVATURE BY ROTATING A ROTARY MOLD IN TWO DIRECTIONS AROUND A FIXED MOLD

摘要

PURPOSE: A stretching and bending apparatus is provided to control spring back of a high-strength formed beam by stretching and bending the formed beam through a bending mod.;CONSTITUTION: A stretching and bending apparatus(100) comprises a bending die(10), a bending mold(30), and an operating unit(50). The bending mold comprises a fixed mold(33) and a pair of rotary molds(31) formed on a straight line extended from the fixed mold. The pair of rotary molds support a formed beam(1) and are rotated at both sides of the fixed mold. The bending mold is installed on the top of the bending die. The operating unit is installed in the bending die and connected to the rotary molds to rotate the rotary molds.;COPYRIGHT KIPO 2012
