Bending die with radial cam unit

摘要

An apparatus includes a backing surface that is operable to support a workpiece, and a mounting structure that is operable to move linearly between a first position and a second position. Movement from the first position to the second position is in a direction toward the backing surface. A first engaging part is fixedly connected to the mounting structure for movement in unison with the mounting structure, wherein the first engaging part is operable to engage a first portion of the workpiece. A second engaging part is rotatably connected to the mounting structure such that the second engaging part rotates with respect to the first engaging part in response to movement of the mounting structure from the first position to the second position, wherein the first engaging part is operable to engage a second portion of the workpiece.

1. An apparatus, comprising:
a backing surface that is operable to support a workpiece such that a supported portion of the workpiece is disposed on the backing surface, a first overhanging portion of the workpiece extends off the backing surface and is not supported by the backing surface, and a second overhanging portion of the workpiece extends off the backing surface and is not supported by the backing surface; a mounting structure that is operable to move linearly between a first position and a second position, wherein movement from the first position to the second position is in a direction toward the backing surface; a first engaging part that is fixedly connected to the mounting structure for movement in unison with the mounting structure, wherein the first engaging part is operable to engage the first overhanging portion of the workpiece during linear motion of the mounting structure from the first position to the second position; and a second engaging part that is rotatably connected to the mounting structure such that a rotational axis of the second engaging part moves in unison with the mounting structure and the second engaging part rotates with respect to the first engaging part in response to movement of the mounting structure from the first position to the second position, wherein the second engaging part is operable to engage the second overhanging portion of the workpiece during linear motion of the mounting structure from the first position to the second position, wherein the first engaging part and the second engaging part move past the supported portion of the workpiece during linear motion of the mounting structure from the first position to the second position, such that the first engaging part and the second engaging part are disposed entirely on a first side of the supported portion of the workpiece in the first position and the first engaging part and the second engaging part are disposed entirely on a second side of the supported portion of the workpiece in the second position.
