摘要：
A device for forming bow springs in a one-piece centralizer includes a swing arm that is configured to receive the one-piece centralizer. The device and process using the device include mechanically applying, with a press, an external load onto an un-formed bow spring positioned on a form of the swing arm. When the load is applied with the device, the un-formed centralizer is forced downward to allow the bow spring to take the desired form/shape/geometry, length, and height of a formed bow spring.
