Patent

CA 2336503

A device for positioning stock within a metal forming machine has a body containing a pusher arm. The device may use interchangeable standard and reverse pusher arms. The pusher arms mount on pivot pins and have position restoring springs. The springs exert force on the pusher arms at a distance from the pivot pins, thereby inducing a moment in the pusher arm. The pusher arm translates this moment into a lateral force exerted by the pusher arm on a piece of stock metal. The body may be mounted in either a reverse or standard configuration resulting, in combination with the use of either the standard or reverse pusher arm, in the ability to exert a lateral force in different directions depending on the configuration used. The device may also have a single pusher arm which may be used in either configuration.
