Process and apparatus for hydroforming a vehicle manifold |
摘要 |
A hydroforming process and apparatus for manufacturing components of a vehicle exhaust or intake manifold. The hydroforming process is utilized to form a tubular member to the desired configuration for use in a manifold. The tubular member is loaded into a hydroform press and filled with a suitable liquid. The liquid within the tube is pressurized in order to maintain a predetermined internal fluid pressure which prevents collapse and crimping of the tube during forming. The hydroform press includes two sets of dies to form a compound bend in the pressurized tube. Upper and lower dies close on the tube first to bend the tube in a vertical plane. Horizontal dies are wedged inwardly spreading the first die set and bending the tube in a horizontal plane. As a result, a compound configuration may be placed on the tube making it suitable for use in a vehicle manifold. |
