ABSTRACT:
An automatic tube shearing system of the type requiring no shearing blades comprising an automatic two-stage tube feed mechanism and a bladeless shear. The feed mechanism comprises a tube loader, a pinch roller type initial drive, a selectively engageable main roller drive and an intermittent drive including a gripper which operates in a precision fashion to feed tube through the shear apparatus. The shear apparatus is of the type requiring tooling, both externally and internally of the tubing to prevent deformation during the bladeless shear operation. The internal tooling comprises a mandrel having a position stabilization rod extending along the tube end feed path and equipped with a pair of spaced apart latches which operate in a complemental fashion to permit tube lengths to be fed onto the mandrel rod and later fed through the shear without ever unlocking the stabilization rod and losing the proper positioning of the mandrel. A unique tube clamp and several methods of using the apparatus to provide substantially continuous tube feed are disclosed.
