摘要 |
A device for the cold deformation of a metal tube section comprises a hydraulic press with two columns in the closed press frame in which are arranged an upper compression cylinder operating against a lower thrust integral with the press frame and a lateral compression cylinder operating against a lateral thrust, the upper compression cylinder, the lower thrust, the lateral compression cylinder and/or lateral thrust being fitted, at their compression ends, with tool elements together form a complete forming toola nd the lateral compression cylinder as well as the lateral thrust being equipped with supplementary attachements for the section. The lateral thrust is made up of a supplementary compression cylinder and at least one of the two lateral compression end with fluid feed and evacuations conduits able to be connected to a regulated source of fluid emerging inside the tube section attachment.
