摘要： Provided is a bending apparatus which can solve the problems of the prior art which carries out two-dimensional or three-dimensional bending of a long metal blank having a closed cross section.
A bending apparatus has (a) a first manipulator (27) which constitutes a feed means which feeds a hollow metal blank (25) having a closed cross section in its lengthwise direction, (b) a second manipulator (29a) which supports a first support means which is disposed at a first position and supports a metal blank while feeding it, a heating means (5) which is disposed at a second position downstream of the first position in the feed direction of the metal blank (25) and which heats all or part of the circumference of the metal blank (25) being fed, and a cooling means (6) which is disposed at a third position downstream of the second position in the feed direction of the metal blank (25) and which cools the portion of the metal blank (25) being fed which was heated by the heating means (5), and (c) a third manipulator (28) which constitutes a second support means which is disposed at a fourth position downstream of the third position in the feed direction of the metal blank (25) and which imparts a bending moment to the heated portion of the metal blank (25) by moving two-dimensionally or three-dimensionally while supporting at least one location of the metal blank (25) being fed to bend the metal blank (25) into a desired shape.
摘要翻译：提供一种弯曲装置，其可以解决现有技术中对具有闭合截面的长金属坯料进行二维或三维弯曲的问题。弯曲装置具有（a）第一操纵器（27），其构成供给装置，该进给装置沿长度方向进给具有闭合截面的中空金属坯料（25），（b）第二操纵器（29a）支撑装置，其设置在第一位置并在供给金属坯料的同时支撑金属坯料;加热装置（5），其设置在金属坯料（25）的进给方向上的第一位置下游的第二位置，并且加热供给金属坯料（25）的全部或部分圆周;以及冷却装置（6），其设置在金属坯料（25）的进给方向上的第二位置下游的第三位置，并且冷却被加热的金属坯料（25）的一部分被加热装置（5）加热，和（c）构成第二支撑装置的第三操纵器（28），该第三操纵器构成第三支撑装置，该第二支撑装置设置在第三位置下游的第四位置金属坯料（25）的进给方向和whi 通过二维或三维地移动来向金属坯料（25）的加热部分施加弯曲力矩，同时支撑进给金属坯料（25）的至少一个位置以将金属坯料（25）弯曲成为所需形状。
