Abstract: A method and device for checking clearance between a stamping die includes a template representative of relative movement between the stamping die and end tool. A template including a surface representing movement of the end tool relative to the stamping die is positioned relative to the stamping die. The position is indicative of a location of the end tool during operation of the stamping die. Contact between the template and the stamping die along the surface representing movement indicates potential contact between the end tool and the stamping die during operation.

Abstract: A rotary cam assembly for a bending die includes first and second arms pivotally attached to an actuator. Linear movement of the actuator causes rotation of the rotary cam relative to a bending cam. A rotatable element is supported between the first and second arms and guides along a cam surface of a fail-safe element mounted on an upper die. In the absence of actuator movement, the fail-safe element cause rotation of the rotary cam from a released position to a bending position ensuring proper position of the rotary cam relative to a bending cam.
