摘要： 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.

摘要： An overload protection device for the clamping portion of a tube cutoff die set. The overload protection device is used to prevent destructive overload forces in the event a mechanical obstruction prevents the tube clamping die jaws from fully closing in response to the forces applied by a control cam. The overload protector comprises a wedge mounted between rollers. If overload occurs the wedge is squeezed out of position against the operation of a compression spring. After the overload condition is eliminated the wedge is returned to position by the compression spring.

摘要： Method for cutting heavy wall steel tubing. The tubing is notched and cut through along a vertical axis but the blade is narrower than the interior diameter so as to leave the side walls uncut. A side wall is preferably notched during the first cut. Thereafter, a second blade is driven horizontally through the side notch to complete the cut.

摘要： A feed apparatus for tubing in which a pair of arms are mounted in scissors fashion and a feed roller and drivingly connected pulley are mounted at each free end of each arm. An endless drive belt is trained around the pulleys and a motor drivingly engages the belt so as to drive the pulleys and thereby the feed rollers. As the arms move in scissors fashion to move the feed rollers into and out of driving engagement with the tubing, the length of the path of the drive belt is shortened but a belt tensioning mechanism operates to compensatingly increase the length of the belt path to maintain a constant tension on the belt and thereby a constant drive to the feed rollers. The tensioning mechanism includes an air cylinder and a tensioning roller secured to the free end of the pistion rod of the air cylinder. A constant air pressure is maintained in the air cylinder so that the tensioning roller is automatically moved outwardly or inwardly to maintain a constant tension on the drive belt as the feed rollers move toward or away from the tubing.

摘要： An apparatus for handling tubing as the tubing is fed to a severing blade for severing into cut sections of predetermined length. The tube handling apparatus includes clamping jaws positioned at the location of the severing blade and a feed tunnel which is arranged rearwardly of the clamping jaws. The feed tunnel includes fingers at its front end which are telescopically received in drilled slots formed on the internal periphery of the clamping jaws so that even very short remnants of tubing occurring after the last full length section of tubing is cut will be maintained in alignment with the tube feed axis by the fingers of the feed tunnel to preclude movement of the remnant tubing into a position of disorientation or dislodgment where it would interfere with the operation of the tube handling apparatus.

摘要： Tube cutoff apparatus of the double cut type wherein a horizontal blade passes across and notches a section of tube wall prior to the entry of a vertical severing blade. The horizontal blade holder assembly comprises a carriage which is interconnected with the base by means of a pair of parallelogram links. In one embodiment the horizontal blade holder assembly is driven through an arcuate path of travel by a depending dogleg cam which is mounted on the upper platen assembly of a die set. In a second embodiment the horizontal blade holder assembly is driven by a linkage including a triangular link and a drive link connected to the upper platen assembly. The result in both cases is to drive the horizontal blade holder assembly through an arcuate path which carries it downwardly and away from the path of the vertical blade in a minimum vertical stroke length. In both embodiments, means are provided for adjusting the vertical position of the notching blade relative to the tube section to accommodate tubes of varying diameter.
