摘要： A device for sequentially stretched straightening a tube and bending same into a U-shape. The device includes a track for guiding a tube. A hold clamp is fixedly positioned on the track. A feed clamp is movably positioned on the track. A feed clamp is movably guided along the track between a first position adjacent the hold clamp and a second position at a stop mechanism. The stop mechanism is reciprocally shiftable along the track and is adapted to control the final increment of travel of the feed clamp during a movement thereof toward the second position. A tube cutting mechanism is oriented adjacent the hold clamp. A control activates the hold clamp to grip the tube while simultaneously effecting a movement of the feed clamp, when the clamping structure thereon is deactivated, away from the hold clamp toward the second position until it reaches the stop mechanism. Thereafter, the clamping mechanism on the feed clamp is activated to grip the tube and the feed clamp is moved to the second position thereof to cause the tube to be stretch straightened. The clamping mechanism on the feed clamp is deactivated following an arrival of the feed clamp at the second position to release the tension accumulated in the tube followed by a reactivation thereof and a deactivation of the clamping structure on the hold clamp.

摘要： A method and apparatus for controlling the orienting of the ends of a finite length segment of tube following a bend thereof through a predefined angle. A supplying and delivering device supplies at least one straight finite length segment of tube to a tube bender for bending the tube about a bend axis. A first end of the finite length segment is oriented a predetermined distance from a bend axis about which the finite length segment is to be bent. The finite length segment is clamped to the bend arbor for movement therewith. The bend arbor is moved through the predefined angle to effect a bending of the finite length segment while simultaneously pushing the first end of said finite length segment toward a location whereat the finite length segment is clamped to the bend arbor. A rate of movement and distance through which the first end is moved is controlled to a ratio of the distance to be moved divided by the number of degrees in the predefined angle, the predetermined distance equalling the ratio multiplied by the number of degrees in said predefined angle.

摘要： A method and apparatus for controlling the orienting of the ends of a finite length segment of tube following a bend thereof through a predefined angle. At least one straight finite length segment of tube is supplied to the tube bender for bending the tube about a bend axis. The two ends of the tube, following the bend, are measured to determine the distance between the end face of each leg to the bend axis. Appropriate adjustment is made to a pushing member to keep the ends of the tube in a generally coplanar relation. Additional measurement is performed to facilitate adjustment between the tube supply device and the tube bending mechanism.

摘要： A mechanical tube expander having a construction which facilitates a machine setup prior to coil assembly without necessitating the machine operator to leave a control panel, this being due to all setup and locking features being accomplished from the control panel. Thus, an operator climbing on ladders to various and remote locations on the machine are not necessary. This feature is accomplished by orienting a pre-size clamp and a strip clamp on opposite sides of the stripper plate and tracking the position of the stripper plate relative to the receiver in order to enable the pre-size clamp to be correctly positioned and clamped to a piston rod driven upwardly by pressurized air. Any retraction of the piston rod will cause oil to be drawn into the upper end of the piston and cylinder assemblies so that at the bottommost stroke of the mechanical tube expander, a valve will be activated to block outflow of oil at the same time that the stripper clamp is clamped to allow bullets to be removed from the tubes in an assembly of fins, after the withdrawal of such bullets the stripper clamp is unclamped to allow the mechanical tube expander to return to a predetermined position to enable another operative sequence to take place.
